# Polyester Yarn for Hoodies & Sweatshirts. **Fiber Guide · B2B Sourcing · Data-Driven** --- ## Hero Polyester has quietly taken over the hoodie market. Walk through any streetwear trade show or college bookstore and the majority of blanks on display — Champion, Gildan HeavyBlend, Next Level, dozens of white-label OEM fleeces — are either 100% polyester or polyester-dominant blends. The reason isn't corner-cutting; it's that polyester fleece delivers a specific performance profile — controlled pill resistance, consistent GSM, sublimation-ready surface, and predictable wash stability — that cotton fleece simply doesn't match in B2B volume production. The data point that anchors this: polyester fleece achieves Martindale pilling grade 4–5 at 2,000 cycles versus cotton fleece's grade 2–3 at the same test standard. For a streetwear brand ordering 2,000 hoodies and selling them at ₹1,800–2,500 retail, pill resistance at six months of wear is a direct returns driver. Polyester solves that problem structurally, not through finishing chemistry. --- ## At a Glance **The comparison, summarised.** | Dimension | Rating | Why | |---|---|---| | Softness / Hand Feel | 7/10 | Modern micro-denier polyester fleece (0.5–1.0 dpf) achieves a genuinely soft hand that surprises buyers expecting a synthetic feel; not identical to cotton fleece but comfortable for all-day wear | | Durability / Abrasion Resistance | 9/10 | Polymer chain structure resists fibre breakage and abrasion; pilling grade 4–5 at 2,000 Martindale cycles — the key metric for hoodie longevity | | Colour Retention / Colorfastness | 8/10 | Disperse-dyed polyester holds grade 4–5 wash fastness at 40–60°C; critical for sublimation-printed hoodies where colour is the entire product proposition | | Breathability / Moisture Management | 5/10 | Polyester fleece traps more heat than cotton fleece; acceptable for casualwear layering but honest limitation for athletic hoodies intended for warmup use | | Stretch & Recovery | 6/10 | Standard polyester fleece offers 15–20% elongation without elastane; adequate for relaxed hoodie fits, insufficient for athletic-cut designs | | Cost Efficiency | 9/10 | Polyester fleece yarn at ₹130–170/kg versus cotton equivalent at ₹210–290/kg — 35–45% raw material saving at volume | | Sustainability / Eco Credentials | 4/10 | Virgin polyester is petroleum-derived; rPET (GRS-certified recycled polyester) is the credible upgrade path and increasingly expected by university/brand buyers | | Ease of Care / Wash Durability | 9/10 | Machine wash at 40°C, tumble dry low, no ironing needed — consumer-friendly care that supports the casualwear positioning | --- ## Why Polyester for Hoodies & Sweatshirts **What makes polyester the right choice for hoodies & sweatshirts.** **01. Pill Resistance — The Metric That Defines Hoodie Quality** Pilling is the failure mode that kills hoodie brand reputation. A consumer who pays ₹2,000 for a branded hoodie and watches it pill into a fuzzy mess after three months of wear doesn't just return the product — they talk about it. The mechanism is straightforward: pilling occurs when short fibre ends on the fabric surface tangle together under friction and abrasion, forming visible fibre balls. Cotton fleece, with its natural fibre length of 25–35mm (even with long-staple Pima at 35–40mm), generates more free fibre ends per unit surface area than polyester filament or high-tenacity spun polyester. Polyester's structural advantage: high-tenacity polyester fibres have a breaking tenacity of 5.5–7.5 cN/dtex, meaning they resist the tensile stress that would normally cause fibre ends to break free and tangle. When pilling does initiate on polyester, the pills remain anchored (attached pilling) rather than dropping off, which paradoxically looks worse in the short term — but this is addressed by specifying anti-pill finish or tightly napped constructions. The Martindale data is unambiguous: polyester fleece grades 4–5 versus cotton fleece's grade 2–3 at 2,000 cycles. For streetwear and college merch buyers, this is the primary specification checkpoint. **02. Sublimation Printing — Polyester's Exclusive Advantage** Sublimation printing — dye-sublimation transfer where ink converts directly from solid to gas under heat (180–210°C) and bonds permanently with polyester polymer chains — is only possible on polyester or polyester-coated substrates. A cotton hoodie cannot be sublimation printed; it requires screen printing, DTG (direct-to-garment), or heat transfer, each with limitations on colour graduation, photographic detail, and edge-to-edge coverage. Polyester hoodies, by contrast, accept sublimation prints with photographic resolution, 100% surface coverage including over seams (when cut-and-sew sublimation process is used), and wash fastness equivalent to the base fabric's disperse dye performance — grade 4–5 at 40–60°C. This makes polyester the mandatory substrate for all-over-print (AOP) hoodies, which represent a significant and growing segment of the streetwear and college merch market. Brands specifying AOP designs have no technically credible alternative to polyester. For brands wanting sublimation on cotton-feel fabric: poly-cotton blends above 65% polyester content accept sublimation with slight colour muting (15–20% lower saturation than 100% polyester) — viable but the polyester content must be confirmed at fabric sourcing stage. **03. Warmth-to-Weight Ratio in Fleece Construction** Polyester fleece achieves its warmth through trapped air in the pile structure, not through fibre mass. A well-constructed 280 GSM polyester polar fleece creates a deeper pile with more air pockets per unit weight than a 280 GSM cotton fleece — which relies on denser yarn structure to achieve equivalent warmth, adding weight without proportionate warmth gain. The engineering comparison: polyester's thermal resistance (CLO value) of approximately 0.15–0.18 per mm of fabric thickness versus cotton's 0.10–0.12 per mm means polyester fleece delivers 25–40% more warmth per millimetre of fabric thickness. In practical hoodie terms: a 300 GSM polyester polar fleece provides warmth equivalent to a 380–400 GSM cotton fleece. The weight saving of 80–100 grams per garment matters for fast fashion and casual streetwear where heavy garments are a comfort negative, and it also reduces shipping cost per unit — a relevant factor at 2,000+ unit order scales. This advantage narrows in French terry constructions (280–320 GSM) where the looped interior primarily serves moisture management rather than insulation, but remains material for mid-layer and outer hoodie applications. **04. Dimensional Stability — Consistent Sizing Across the Programme** Cotton hoodies shrink. The industry standard expectation is 4–8% shrinkage in length and 3–6% in width after the first wash for ring-spun cotton fleece, even after commercial pre-shrink finishing. This is manageable when it's predictable, but it creates customer service challenges: a size L hoodie that shrinks to a size M after washing is a return, not a sizing variation. Pre-shrinking (Sanforization) reduces but doesn't eliminate this — Sanforized cotton typically shrinks 1–3% residually. Polyester fleece, properly heat-set at the mill, shrinks less than 2% in both dimensions after the first wash at 40°C and accumulates less than 3% total dimensional change after 20 washes. For college merch buyers managing name-drop programmes across multiple universities — where consistent sizing is a compliance requirement and returns are expensive — polyester's dimensional stability simplifies production QC and reduces post-sale service overhead. Streetwear brands also benefit from size grading consistency: when a customer buys a second hoodie in a different colourway 6 months later, the fit should match. With polyester, it does. --- ## Technical Specifications **Manufacturing specs for polyester hoodies & sweatshirts.** **GSM Range** - Lightweight hoodie / spring-weight sweatshirt: 240–280 GSM - Standard casual hoodie (the majority of the market): 280–320 GSM - Heavyweight / premium streetwear hoodie: 320–380 GSM - Ultra-heavyweight / structured drop-shoulder: 380–450 GSM - Note: Polyester achieves equivalent warmth at lower GSM than cotton — a 300 GSM polyester is roughly equivalent in warmth to a 360–380 GSM cotton fleece **Yarn Count** - Ground yarn (body of knit): 20s–30s Ne spun polyester for standard hoodies; 16s–20s Ne for heavyweight - Pile yarn (fleece interior): Lower twist, higher denier for softer hand — 150D–300D polyester typically used in polar/micro fleece; 20s–30s Ne for French terry loops - Sublimation-specific: Higher polyester content in face yarn (minimum 92% polyester on face); inner can be cotton-blend if comfort is priority **Knit Construction** - French terry: Most common for mid-weight hoodies (280–320 GSM) — flat face for print/embroidery, looped reverse for comfort and moderate warmth - Polar fleece: Napped both sides for warmth; better pile construction from double-knit base at 300–380 GSM - Interlock: Higher dimensional stability, less stretch — used for structured silhouettes - Single jersey hood panel: Some constructions use jersey for hood while fleece for body — common in athletic-cut hoodies **Shrinkage** - Heat-set polyester fleece: Length <2%, Width <2% after wash at 40°C - Non-heat-set: Length 3–5% — always specify heat-set - After 10 washes at 40°C: Cumulative <3% for properly finished fabric **Pilling Resistance** - Standard polyester fleece: Grade 4 at 2,000 Martindale cycles (ISO 12945-2) - Anti-pill polyester fleece: Grade 4–5 at 2,000 cycles — achieved through tighter pile construction and/or finishing treatment - Cotton fleece for comparison: Grade 2–3 at 2,000 cycles **Colorfastness** - Disperse dyed solid colours — Wash (ISO 105-C06 at 40°C): Grade 4–5 - Sublimation printed — Wash (ISO 105-C06 at 40°C): Grade 4 - Light fastness (ISO 105-B02): Grade 4–5 (important for outdoor-worn hoodies) - Rubbing dry/wet (ISO 105-X12): Grade 4/3 **Tensile Strength** - Standard spun polyester fleece: Warp/weft tensile 250–400 N (ASTM D5034) - This is adequate for casual garment applications; not a primary spec driver for hoodies **MOQ Guidance** - Stock polyester fleece (commodity colours): 200–500 metres from Tirupur mills - Custom solid colour: 500–1,000 metres minimum - Sublimation-ready white base fabric: Often available from 100–200 metres (high demand item) - Finished blank hoodies OEM: 300–500 pieces per style-colour; 500–1,000 pieces for custom construction --- ## Manufacturing & Sourcing Considerations **What to know before you source.** **Machine Requirements** Polyester fleece is produced on circular knitting machines — typically 3-thread fleece machines or interlock machines for tighter constructions. Standard 18–24 gauge circular knitting handles spun polyester yarn well; yarn tension settings require calibration versus cotton because polyester elongates differently. French terry construction on circular machines produces the looped reverse; polar fleece requires additional napping/raising on Goff or Garnett machines post-knitting to raise the pile on both sides. For cut-and-sew sublimation AOP hoodies, fabric must be knitted in open-width (rather than tubular) to enable flat printing before cutting. This is a critical sourcing requirement — confirm open-width capability with knitting mill for sublimation programmes. **Dyeing Compatibility** Solid-colour polyester hoodies: Disperse dye at 130–135°C under HT/HP conditions in jet dyeing machines. Batch-to-batch shade variation in jet dyeing is the primary QC risk for multi-lot orders — request shade bands from mill and test against Pantone standard before production approval. Sublimation-printed hoodies: The base fabric is typically dyed white (optical white) or a light ground colour. The sublimation ink is then transferred at 180–210°C under pressure using a rotary or flatbed calender press. Critical requirement: polyester content on the print face must be minimum 90–95% for full colour saturation. Confirm with print supplier — many sublimation print shops specify fabric requirements in their tech packs. **Finishing Processes** - Heat-setting: Mandatory — stenter at 175–195°C stabilises GSM and dimensions - Napping/raising: Polar fleece requires mechanical raising to achieve soft pile; specify pile height and both-side vs single-side napping - Anti-pill finish: Enzymatic or mechanical anti-pill treatment on fabric face; specify requirement upfront — not a standard default - Softener: Silicon softeners improve hand feel on polyester fleece; specify wash-off softeners for sublimation substrates to avoid coating interference with ink transfer - Pre-shrink: Less critical for polyester than cotton but still recommended as a QC standard **Quality Control Checkpoints** - Yarn certification: Breaking tenacity minimum 4.5 cN/dtex for standard applications - GSM: Within ±5% of specification — fleece constructions are more variable than single jersey - Pilling: Martindale test at 2,000 cycles minimum grade 4 before production sign-off - Sublimation colour check: Print a test panel before committing to full fabric production; polyester content variation between fabric lots changes colour output - Dimensional stability: Wash 3 fabric samples before CMT approval **Common Production Pitfalls** - GSM variation in fleece: Raising/napping process affects final GSM; fleece is inherently more variable than woven — accept ±7% tolerance or tighten at additional cost - Pile direction in sublimation: Consistent pile direction required for even colour; mark warp direction on all fabric rolls going to print - Seam puckering: Polyester fleece's low elongation at seams requires appropriate needle size (90/14 ballpoint), stitch length (2.5–3.0mm), and compatible polyester thread — cotton thread on polyester fleece causes differential shrinkage puckering - Shade variation between back and face yarn: In two-yarn constructions (separate face/back yarn), ensure consistent dye lot **Lead Times** - Yarn to finished fabric: 3–5 weeks (fleece constructions slightly faster than complex wovens) - Sublimation printing lead time (after fabric receipt): 1–2 weeks for standard AOP - Garment CMT (cut, make, trim): 3–5 weeks for standard hoodie construction - Total new style cycle: 8–12 weeks; sublimation AOP hoodies add 1–2 weeks for print - Blank polyester hoodies from stock inventory: 2–3 weeks **Key Sourcing Regions** - Polyester fleece fabric: Tirupur (India) for knit fleece; Zhejiang (China) for polar/high-GSM fleece - Sublimation printing: Tirupur has significant sublimation print capacity; Dhaka, Bangladesh growing - Finished blank hoodies: Bangladesh dominant for volume; Tirupur for India-domestic; Vietnam for premium --- ## Trade-Offs — Honest Assessment **Every fibre has limits. Here's the full picture.** **Strengths** - **Pilling resistance is structurally superior to cotton.** Grade 4–5 at 2,000 Martindale cycles is a specification that directly reduces returns and extends visible garment quality over a 1–2 year wear cycle. Cotton fleece at grade 2–3 pills visibly within 3–6 months of regular wear. - **Sublimation printing capability is exclusive to polyester.** AOP, photographic-quality prints, full-surface colour, edge-to-edge coverage — none of these are achievable on cotton. For brands with print-heavy identity propositions, polyester isn't a compromise; it's the only substrate. - **Dimensional stability simplifies size management.** Less than 2% shrinkage after heat-setting means consistent sizing across the garment's life and across multiple reorder production runs — a significant operational simplification for college merch and uniform buyers. - **Warmth-to-weight advantage.** A 300 GSM polyester polar fleece is meaningfully warmer than a 300 GSM cotton fleece while weighing the same — relevant for lightweight but warm hoodie propositions and for reducing per-unit shipping cost at volume. - **Cost efficiency at scale.** 35–45% lower raw material cost versus cotton creates margin headroom for investment in better construction details (YKK zippers, reinforced kangaroo pocket seams, ribbed cuffs) without increasing landed cost. - **Colour consistency across large runs.** Disperse dye on polyester achieves tighter batch-to-batch ΔE than reactive-dyed cotton, reducing colour dispute risk on multi-thousand-unit corporate programmes. **Limitations** - **Cotton fleece hand feel is genuinely different.** Premium cotton fleece (420–500 GSM, ring-spun, brushed interior) has a softness and drape that polyester hasn't replicated. Consumers who specifically seek cotton hoodies will notice the difference. This matters most for premium lifestyle brands where tactile experience is part of the product positioning — for these, a tri-blend (50% cotton / 25% polyester / 25% rayon) or cotton-poly blend is a more honest recommendation than 100% polyester. - **Heat retention in active use is a real limitation.** Polyester fleece's lower MVTR (moisture vapour transmission rate) means wearers get hot faster during light physical activity. For hoodies positioned as athletic warmup layers or gym-to-street products, moisture-wicking engineered constructions with mesh panels or open-back knit structures are necessary — adding ₹40–70 per metre in fabric cost over standard fleece. - **Microplastic shedding is increasing scrutiny from B2B buyers.** Polyester fleece sheds more microplastic fibres than woven polyester due to the larger surface area of raised fibres. Research cites 700,000–1,500,000 fibres per wash cycle. While not yet a procurement disqualifier in most markets, university sustainability offices and corporate ESG procurement teams are beginning to ask for data. rPET specification partially addresses brand narrative without solving shedding. - **Static and cling in dry environments.** Polyester's high electrical resistivity causes static cling against other garments and skin. Antistatic finishing mitigates this for 15–25 washes; conductive yarn is overkill for casualwear. Most buyers accept this as a minor consumer experience negative and don't specify actively against it. --- ## Cost Analysis **The economics of polyester for hoodies & sweatshirts.** **Yarn Cost** - Standard spun polyester (20s–30s Ne): ₹130–170/kg - Micro-denier polyester (for soft-hand fleece): ₹160–210/kg - Recycled polyester GRS-certified: ₹155–200/kg - Comparison: Ring-spun cotton equivalent: ₹210–290/kg; tri-blend (cotton/poly/rayon): ₹240–320/kg blended cost **Estimated Cost-Per-Garment Impact** For a standard 300 GSM hoodie (size M, approximately 500–550g fabric weight including ribbing): - Polyester fabric cost at fabric stage: ₹95–130 - Cotton fleece equivalent: ₹150–200 - Tri-blend equivalent: ₹175–235 - Fabric cost saving (polyester vs cotton): ₹55–70 per garment — at 2,000 units, this is ₹110,000–140,000 raw material saving **Cost-Per-Wear Calculation** Assumptions: ₹850 manufacturing cost (fabric + CMT for a quality streetwear hoodie), worn 2× weekly, washed weekly, 2-year service life: - Polyester hoodie pilling grade 4–5: Maintains presentable appearance through 2 years of weekly washing (100+ wash cycles); cost per wear = ₹850 ÷ 208 wears = ₹4.09/wear - Cotton fleece pilling grade 2–3: Visibly pilled at 3–6 months, often retired or worn only at home after 12 months; effective service life 12–18 months; cost per wear = ₹850 ÷ 130 wears = ₹6.54/wear - Polyester delivers 37% lower cost-per-wear from superior pilling performance alone **Comparison to Alternatives for Hoodies** - vs. 100% cotton fleece: Polyester 35–45% lower material cost + longer service life = clear economics winner; cotton wins on hand feel - vs. tri-blend (50/25/25): Tri-blend costs 15–25% more than polyester but achieves superior hand feel and a premium retail positioning — justified for lifestyle brands at ₹2,500+ retail price point - vs. cotton-poly blend (80/20): Minimal cost saving over 100% cotton; moderate pilling improvement; sublimation not viable — a middle-ground that satisfies neither performance camp fully **ROI for Streetwear Brands** Lower return rates are the key ROI driver: if pilling-related returns represent 8–12% of cotton hoodie units (industry-reported range for mid-price casualwear), and polyester reduces this to 2–4%, the saving on a 2,000-unit run at ₹1,800 average selling price is ₹72,000–144,000 — exceeding the raw material cost saving. For college merch buyers, consistent sizing reduces the exchange overhead that consumes post-event inventory management budgets. --- ## Sustainability Profile **Environmental and ethical considerations.** **Carbon and Water Footprint** Virgin polyester fleece carries approximately 5.5–6.0 kg CO₂e per kg of fibre — higher than cotton (1.5–2.5 kg CO₂e/kg excluding irrigation water) on a carbon basis, but cotton's water footprint (10,000–20,000 litres/kg including field water) dwarfs polyester's 17 litres/kg. These trade-offs don't resolve cleanly; the relevant question for a brand is which environmental metric their customer base weights most heavily. Recycled polyester (rPET) from post-consumer bottles reduces carbon footprint to approximately 2.5–3.0 kg CO₂e per kg, and GRS certification provides the chain-of-custody documentation needed for verified sustainability claims. For college and university merch buyers operating under institutional sustainability policies, GRS-certified rPET is increasingly a programme requirement rather than an optional upgrade. **Available Certifications** - OEKO-TEX Standard 100: Harmful substance testing for skin-contact comfort wear — foundational requirement - Global Recycled Standard (GRS): For recycled content claims; required for any "made with recycled materials" marketing - bluesign: Chemical management in dyeing and finishing — relevant for brands with premium sustainability positioning - WRAP (Worldwide Responsible Accredited Production): Social compliance certification for manufacturing facilities — increasingly requested by university procurement offices **Biodegradability / End-of-Life** Polyester fleece is not biodegradable. Post-industrial yarn and fabric scrap from mills is mechanically recyclable through established rag-to-yarn recovery systems in Tirupur and Panipat. Post-consumer hoodie recycling is nascent — brands can support take-back programmes but the downstream processing infrastructure is limited. Chemical recycling (depolymerisation) is emerging at commercial scale in Europe and will likely be relevant within 5 years. **Consumer Perception in Streetwear and College Merch** The sustainability conversation in streetwear is accelerating — driven by younger buyers (18–25 demographic) who actively research brand supply chains. rPET is the accessible, credible story: "Made from X recycled bottles" is a concrete claim that resonates in this audience. Cotton's natural origin still carries premium perception, but the narrative is shifting as awareness of cotton's water footprint grows. Brands that specify rPET and back it with GRS documentation are positioned ahead of the regulatory and consumer expectation curve. --- ## FAQ **Polyester for hoodies & sweatshirts — answered.** **1. What makes polyester better than cotton fleece for hoodies at B2B volume?** Two things dominate: pilling resistance and sublimation capability. Cotton fleece grades 2–3 on the 5-point Martindale pilling scale at 2,000 cycles; polyester grades 4–5. At volume, pill-related returns at 6–12 months are a significant cost — polyester eliminates most of this. For print-heavy propositions, sublimation on polyester achieves photographic resolution, edge-to-edge coverage, and grade 4 wash fastness that screen printing on cotton can't match. Where cotton genuinely wins is premium hand feel — if tactile softness is your brand differentiator, a tri-blend or brushed cotton fleece is more honest. **2. What's the minimum order quantity for polyester hoodie fabric?** Stock polyester fleece in commodity colours (black, white, grey, navy) is available from 200 metres at most Tirupur and Chinese mills. Custom solid colours require 500–1,000 metres for accurate shade matching in HT dyeing. Sublimation-ready white base fabric is high-volume stock and often available from 100 metres. For finished blank hoodies from OEM factories, minimum 300–500 pieces per style-colour. For custom sublimation AOP hoodies (cut-and-sew from printed panels), minimum 200–300 pieces per design is typical at established Tirupur print-and-sew operations. **3. How does polyester fleece hold up after 30+ home wash cycles?** Properly finished polyester fleece is essentially unchanged at 30 washes at 40°C. Pilling grade remains at 4–5 if anti-pill construction was specified; colour holds at grade 4 wash fastness (slight tonal deepening is common, not fading); dimensions stay within ±3% cumulative from the original heat-set geometry. The degradation modes that do appear: ribbed cuffs and waistband lose stretch recovery slightly (4–6% at 30 washes, more with elastane addition), zipper pull cords abrade the adjacent fabric on cheaper constructions (specify coated zipper pulls or protective placket), and sublimation prints on poly-cotton blends show colour shift if washed above 60°C — specify 40°C wash in consumer care labels. **4. What GSM should I specify for a streetwear hoodie?** Most successful streetwear hoodies in the ₹1,800–3,500 retail segment use 300–340 GSM. Below 280 GSM feels lightweight and cheap in hand; above 380 GSM starts to feel heavy and structured, which suits specific drop-shoulder or oversized silhouettes but not the broader market. The sweet spot: 300–320 GSM polyester fleece with a micro-denier face yarn (0.7–1.0 dpf) for softness and a French terry or polar fleece construction. For college merch where price is more constrained, 260–280 GSM is commercially accepted. Confirm GSM on received fabric rolls with in-house testing — fleece constructions vary more than woven fabrics. **5. Is 100% polyester suitable for sublimation all-over-print hoodies?** Yes — it's the only substrate that works properly. Sublimation dye converts to gas at 180–210°C and bonds with polyester polymer chains; on cotton or linen this bond doesn't form and the print washes off. For full-saturation AOP with photographic quality, specify 100% polyester base fabric, optical white ground, open-width knitting (for flat panel printing before cut-and-sew), and a smooth face construction (French terry rather than raised polar fleece — pile interrupts print sharpness). For cut-and-sew AOP, account for 15–20% fabric wastage in nesting patterns versus non-AOP hoodies. **6. What certifications should I look for when sourcing polyester hoodie fabric?** For product safety and chemical compliance: OEKO-TEX Standard 100 (confirm Class I or II for direct skin contact). For recycled content claims: GRS (Global Recycled Standard) — chain of custody from PET bottle to finished yarn. For social compliance on factory audits: WRAP or BSCI certification is commonly accepted by institutional buyers. For sublimation printing specifically: confirm ink supplier OEKO-TEX compliance — sublimation inks contain disperse dye chemistry that needs substance testing. For EU market: REACH compliance on all chemical inputs. Request actual test reports with issue dates, not just certificates. **7. How does polyester fleece handle sublimation printing compared to cotton blend fabrics?** 100% polyester achieves the highest colour saturation in sublimation — vibrant, accurate colour with photographic resolution. At 65/35 polyester-cotton, colour saturation drops by roughly 15–20% (the cotton fibres don't accept sublimation dye, so the ground shows through slightly in pale areas). At 50/50 poly-cotton, sublimation is marginal — possible but noticeably muted; most print suppliers won't accept fabric below 60% polyester content. The lesson: if sublimation is your primary printing method, commit to 95–100% polyester construction. If you want a blend for hand-feel reasons, accept the print quality trade-off and test on your specific fabric before committing to a print run. **8. What's the typical lead time for polyester hoodie orders?** For stock fabric + new cut-and-sew construction: 8–11 weeks total (2 weeks pre-production sampling, 3–4 weeks fabric production, 3–5 weeks CMT). For sublimation AOP hoodies, add 1–2 weeks for print production after fabric receipt. For reorders of established constructions in stock fabric: 4–6 weeks CMT-only. Blank hoodie stock programmes (pre-agreed fabric specs with scheduled delivery): lead time can compress to 3–4 weeks for in-season replenishment. College merch buyers: order at minimum 10–12 weeks ahead of event dates — the autumn semester rush (August–September) stresses Tirupur CMT capacity significantly; orders placed in May–June receive better pricing and scheduling. --- ## Related Links **Related Applications for Polyester** - [T-Shirt Manufacturing](/yarn/polyester-t-shirt-manufacturing) - [Activewear](/yarn/polyester-activewear) - [Sportswear](/yarn/polyester-sportswear) - [Workwear](/yarn/polyester-workwear) - [Polo Shirts](/yarn/polyester-polo-shirts) - [Athleisure](/yarn/polyester-athleisure) **Alternative Fibers for Hoodies & Sweatshirts** - [Cotton Hoodies & Sweatshirts](/yarn/cotton-hoodies-sweatshirts) - [Tri-Blend Hoodies & Sweatshirts](/yarn/tri-blend-hoodies-sweatshirts) - [Cotton-Poly Blend Hoodies & Sweatshirts](/yarn/cotton-poly-blend-hoodies-sweatshirts) **Glossary** - [GSM — What It Means for Fabric Weight](/glossary/gsm) - [Colorfastness — Wash, Light, and Rub Ratings Explained](/glossary/colorfastness) - [Pilling — Martindale Scale and Prevention](/glossary/pilling) **Compare** - [Polyester vs. Other Fibers — Full Comparison](/compare/polyester)
