# Cotton Yarn for T-Shirt Manufacturing **Fiber Guide · B2B Sourcing · Data-Driven** --- ## Cotton Yarn for T-Shirt Manufacturing. Cotton remains the dominant fiber in global t-shirt production for reasons that go beyond tradition — its natural staple structure (20–32mm for standard grades, 32–38mm for premium long-staple) creates a yarn architecture that behaves predictably across every stage of cut-and-sew production. For t-shirt manufacturing specifically, the single-jersey knit construction amplifies cotton's natural properties: moisture absorption up to 8.5% of its dry weight, thermal regulation that keeps the fabric comfortable across a 15–35°C ambient range, and a surface receptivity to reactive dyes that polyester and synthetics simply cannot match. The critical differentiator is staple length — 28mm+ combed cotton reduces surface fibre ends by up to 40% versus carded, directly translating to a softer hand feel and longer print life. At standard production volumes (5,000–50,000 units), ring-spun combed cotton in the 30s Ne range is the industry-standard specification for a reason: it threads the needle between cost, softness, and print quality better than any alternative. --- ## At a Glance *The comparison, summarised.* **Softness / Hand Feel — 8/10** Ring-spun combed cotton at 30s–40s Ne delivers a hand feel that competes with modal and bamboo at a fraction of the cost. The limitation is that raw cotton without finishing treatment (bio-polish, silicone softener) can feel stiff off the knitting machine; this is a processing variable, not a fibre limitation. **Durability / Abrasion Resistance — 7/10** Standard cotton t-shirt fabric (160–180 GSM, single jersey) achieves 8,000–12,000 Martindale cycles before visible pilling, which is adequate for a garment worn against the skin with low abrasion contact. Heavier interlock constructions push this to 15,000+. **Colour Retention / Colorfastness — 8/10** Reactive dyeing of cotton achieves ISO 105-C06 wash fastness of 4–5 (excellent), and rub fastness of 3–4. Darker shades (navy, black) in low-pH reactive systems require fixation at 60°C+ — skip this and you lose 0.5–1 grade within 5 wash cycles. **Breathability / Moisture Management — 9/10** Cotton absorbs moisture vapour before the wearer feels wet — this is the "comfort window" that drives t-shirt purchasing decisions. In single jersey at 160 GSM, moisture vapour transmission rate (MVTR) runs 800–1,200 g/m²/24h, outperforming standard polyester at the same weight. **Stretch & Recovery — 5/10** Pure cotton has minimal elastic recovery. A 30s single jersey will stretch 15–20% in the width direction and recover to within 3–5% of original dimension after 24 hours. This is acceptable for t-shirts but means you need accurate grading — cotton tees that start tight will stay tight. Adding 3–5% spandex changes this rating to 8/10. **Cost Efficiency — 8/10** At ₹250–320/kg (Ne 30s ring-spun combed, Indian origin) or $3.00–4.50/kg FOB, cotton remains the most cost-effective softness-per-rupee fibre for t-shirts. Cost efficiency drops when buyers over-specify — Ne 40s combed costs 18–22% more than Ne 30s for a hand-feel improvement most end consumers cannot perceive. **Sustainability / Eco Credentials — 6/10** Conventional cotton uses 1,500–2,000 litres of water per kilogram of fibre — a genuine environmental liability. GOTS-certified organic cotton addresses chemical inputs but not water consumption. BCI (Better Cotton Initiative) offers water-reduction frameworks but is a process standard, not a chemical-free guarantee. **Ease of Care / Wash Durability — 7/10** Cotton t-shirts washed at 40°C in household machines for 30+ cycles maintain acceptable colour and dimensional stability if pre-shrunk correctly at the manufacturing stage. The gap between well-manufactured and poorly-manufactured cotton tees is entirely in the pre-shrink protocol. --- ## Why Cotton for T-Shirt Manufacturing *What makes cotton the right choice for t-shirt production.* **01 — Ring-Spun Structure Creates the Surface Feel Customers Pay For** The spinning method matters more than fibre grade for most t-shirt applications. Ring-spun yarn is produced by continuously twisting and thinning the fibre bundle, aligning staple fibres parallel along the yarn axis. This alignment reduces the number of free fibre ends protruding from the surface — what you feel as roughness or pilling. A 30s Ne ring-spun cotton yarn has approximately 60% fewer surface fibre ends than the same count in open-end (rotor) spun format. For t-shirt manufacturing, this is directly perceptible: consumers running a hand across the fabric surface feel smoothness, not texture. For brands building repeat purchase rates, that tactile first impression is a genuine commercial variable. Ring-spun also packs more evenly into knitted loops, giving single jersey fabrics a tighter, more uniform appearance that holds screen-print ink more predictably. The cost premium over open-end spun yarn is typically 15–25% at Ne 20s–30s — fully justified when your garment retails above ₹499 or $8. **02 — GSM Specification Determines Where Your Product Sits in the Market** T-shirt GSM is not arbitrary — it maps directly to positioning, price point, and garment end-use. Lightweight cotton singles at 120–140 GSM target summer activewear and children's wear where breathability outweighs durability. The mainstream adult t-shirt market (promotional, fast fashion, casualwear) runs at 150–180 GSM in single jersey, Ne 20s–30s, with enough body to resist bagging but light enough for all-day comfort. Premium branded tees — the segment Boring Label operates in — sit at 180–220 GSM using Ne 30s–40s combed, where the added weight creates a draped, substantial hand feel that signals quality before the customer reads the label. At 220–240 GSM, single jersey with Ne 20s, you're producing t-shirts that blur into lightweight sweatshirt territory — popular for autumn layering pieces. Specifying the wrong GSM for your target market is one of the most common sourcing errors: a 160 GSM blank feels cheap against a 200 GSM premium tee in direct comparison, even if the fibre grade is identical. **03 — Reactive Dyeing Compatibility Unlocks the Full Colour Range** Cotton's cellulosic structure forms covalent bonds with reactive dyes — the same chemistry that makes cotton the easiest fibre to dye in deep, repeatable shades. This matters for t-shirt brands because colour consistency across production runs is a real problem in the industry: polyester requires disperse dyes at 130°C under pressure, which most vertical knit-to-finish mills do not run in the same dye house as cotton. When you run a cotton-only program, you have access to any reactive chemistry — H-reactive for bright shades, VS-reactive for better wash fastness in darks, and vat dyes for extreme wash-fastness applications. ISO 105-C06 wash fastness of 4–5 is achievable across the full colour gamut. For t-shirt brands running direct-to-garment (DTG) printing, cotton's surface receptivity creates 35–50% higher ink absorption efficiency versus polyester, directly reducing ink cost per unit and improving colour vibrancy. **04 — Pre-Shrink Protocol Is the Differentiator Between Brands and Commodity** The single biggest quality gap in cotton t-shirt manufacturing is not the fibre — it's shrinkage control. Untreated cotton single jersey shrinks 6–10% in length and 4–8% in width after the first wash (ISO 6330, 40°C domestic wash simulation). A brand selling a "medium" tee that fits like a small after washing gets returned, loses the customer, and pays the return logistics cost. Professional pre-shrink treatment compresses this to 2–3% length and 1–2% width through a combination of wet relaxation (open-width washing under low tension), mechanical sanforising (compressive shrinkage at the finishing stage), and heat-setting at controlled temperatures. The equipment cost is why many low-end mills skip this step — sanforising machines represent a ₹2–5 crore capital investment. When qualifying a new manufacturing partner, ask specifically for AATCC 135 pre-wash and post-wash dimensions — the numerical difference tells you exactly what their finishing line looks like. --- ## Technical Specifications *Manufacturing specs for Cotton T-Shirt Manufacturing.* **GSM Range** - 120–140 GSM: Promotional tees, children's wear, summer basics — Ne 20s–24s single jersey - 150–180 GSM: Mainstream adult t-shirts, branded basics, casualwear — Ne 24s–30s single jersey - 180–220 GSM: Premium branded tees, structured silhouettes — Ne 30s–40s single jersey or 2×1 interlock - 220–240 GSM: Heavyweight t-shirts, autumn/winter tees, structured collar styles — Ne 20s–24s **Yarn Count** - Ne 20s–24s: Standard weight tees, open-end or ring-spun acceptable, cost-optimised - Ne 30s: The industry sweet spot — ring-spun combed preferred, balances hand feel and production cost - Ne 40s: Premium fine jersey, noticeably softer, higher breakage risk on standard circular knitting machines; requires slower machine speeds - Ne 60s: Luxury fine jersey territory, requires specialised equipment and significantly higher waste percentages **Knit Construction** - Single jersey (1-thread): Industry standard for t-shirts, runs at 24–28 gauge; lightest and most breathable - Interlock (2-thread, locked): Heavier, more stable, less curl at edges — preferred for polo-shirt bodies and structured tees - 1×1 rib: Used for collar, cuff, and hem bindings; elasticity comes from rib structure, not fibre content - Piqué (single or double): Polo shirt standard; heavier texture, better air circulation, requires specific needle configuration **Shrinkage (ISO 6330, 40°C, 3 wash cycles)** - Without pre-shrink treatment: Length 6–10%, Width 4–8% - With standard sanforising: Length 2–4%, Width 1–3% - With full wet relaxation + sanforising: Length 1.5–2.5%, Width 0.5–1.5% - Acceptable quality standard for most brands: ≤3% length, ≤2% width **Pilling Resistance** - Single jersey (Ne 30s ring-spun combed): 3–4 (Martindale, ISO 12945-2) - Interlock construction: 4 (more loops locked, fewer free ends) - Open-end spun cotton: 2–3 (higher surface fibre count) **Colorfastness (ISO 105 series)** - Wash fastness (C06): 4–5 with reactive dyes, correct fixation chemistry - Light fastness (B02): 4–5 for most shades; pale pastels 3–4 - Dry rub fastness (X12): 4–5; wet rub: 3–4 (inherent limitation of reactive dye system) **Tensile Strength** - Single jersey weft: 180–250 N/50mm (ISO 13934-1) - Interlock: 280–350 N/50mm - Minimum acceptable for t-shirt application: 150 N/50mm **MOQ Guidance** - Yarn purchase: 500 kg minimum per count and colour from most Indian spinning mills - Fabric (greige): 500–1,000 metres minimum per construction - Finished garment (FOB India): 300–500 units per style/colour for tier-2 manufacturers; 100–200 units for premium CMT units --- ## Manufacturing & Sourcing Considerations *What to know before you source.* **Machine Requirements** Standard cotton single jersey for t-shirts runs on 24-gauge circular knitting machines — the most widely available gauge globally. Ne 30s is the lightest yarn that runs reliably on 24-gauge without excessive breakage; Ne 40s requires 28–32 gauge and corresponding machine investment. Indian knitting clusters (Tiruppur, Ludhiana) have 24-gauge capacity in abundance; 28-gauge capacity is present but less competitive on price. If your specification calls for fine-gauge interlock (28+ gauge), build in an extra 2–3 weeks for machine scheduling. **Dyeing Compatibility** Cotton's cellulosic structure is dyed exclusively with reactive, vat, or direct dyes in t-shirt applications. Reactive dyes (Huntsman Novacron, DyStar Remazol) are the industry standard — they create covalent bonds with cellulose at pH 10.5–11.5, delivering the best wash fastness. Vat dyes offer superior light fastness but require sodium hydrosulfite reduction chemistry that many mills are phasing out for environmental compliance reasons. Direct dyes are used only in low-cost promotional tees where wash fastness is not a priority. Specify reactive dye + fixation chemistry explicitly in your purchase order terms. **Finishing Processes** - Bio-polishing (cellulase enzyme treatment): Removes surface fibre ends, dramatically improves hand feel and pilling resistance; adds ₹8–15/metre to processing cost - Mercerisation: Caustic soda treatment that swells the fibre lumen, increasing lustre and dye uptake by 10–15%; standard in premium tee manufacturing - Softener application: Silicone softeners improve hand feel but reduce moisture absorption — specify amino-silicone softener for balance of softness and breathability - Compacting/sanforising: Non-negotiable for any brand requiring dimensional stability **Quality Control Checkpoints** 1. Yarn incoming: Ne count verification, twist per inch (TPI), moisture content (should be 6–8%) 2. Greige fabric: GSM ±5% tolerance, width consistency, fabric defect inspection (4-point system) 3. Post-dye: Shade matching against approved standard (CMC ΔE ≤1.0 preferred, ≤1.5 acceptable) 4. Post-finishing: Dimensional stability (pre/post wash dimensions), pilling test, hand feel evaluation 5. Cut panels: Shade banding check across rolls — critical for avoiding mixed shades in one shipment **Common Production Pitfalls** - Roll-to-roll shade variation: Cotton dye uptake varies with greige fabric batch; always dye from a single greige lot when possible - Uneven shrinkage across garment panels: Different fabric rolls processed through finishing at different tension settings; fix with consistent open-width finishing at standardised belt speeds - Bowing and skewing: Knitted fabric has inherent spiral distortion; requires straightening frames in finishing **Lead Times (India, FOB basis)** - Yarn to finished fabric: 3–4 weeks - Full CMT production: 6–10 weeks from approved tech pack - Rush production: 4 weeks minimum; expect 8–12% premium on CMT cost **Key Sourcing Regions** - India: Tiruppur (global epicentre for cotton t-shirts), Ludhiana (heavier constructions), Surat (fabric supply) - Bangladesh: Cost-competitive for volumes above 10,000 units; longer lead times - Turkey: Premium positioning, excellent finishing quality, 40–60% higher CMT cost than India - China: Best for technical specifications and unusual constructions; currency risk and trade policy exposure --- ## Trade-Offs — Honest Assessment *Every fibre has limits. Here's the full picture.* **Strengths** - **Universal machine compatibility.** Cotton in Ne 20s–40s runs on standard circular knitting equipment available in every major garment manufacturing cluster globally. You will never have a machine availability problem with a standard cotton specification — unlike bamboo, modal, or Tencel which require specialised handling. - **Reactive dye depth and repeatability.** ISO 105-C06 wash fastness of 4–5 across the full colour spectrum is the practical ceiling for t-shirt applications, and cotton achieves it routinely with standard reactive dye chemistry. This is why athletic and premium brands default to cotton for their hero colourways — navy, black, and white maintain their integrity across 30+ wash cycles when correctly finished. - **Consumer acceptance is built-in.** Market research across multiple apparel categories consistently shows that "100% cotton" as a label claim outperforms "modal blend" or "bamboo" in initial purchase conversion among consumers above 30 — particularly in workwear, casualwear, and gifting contexts. - **Print substrate performance.** Screen printing on cotton achieves 30–50% higher ink opacity than on polyester at equivalent discharge rates. DTG printing on 100% ring-spun cotton outperforms polyester blends on all quality metrics. If your margin model includes decorated tees, cotton is not negotiable. - **Cost predictability.** Cotton futures are traded on ICE, and Indian yarn prices are publicly indexed. You can model your cost of goods 6–12 months forward with reasonable accuracy — unlike Tencel, modal, or bamboo where pricing is controlled by fewer manufacturers. **Limitations** - **Shrinkage requires investment in finishing infrastructure.** Cotton will shrink — the question is whether it shrinks before or after the garment reaches the customer. Brands sourcing from mills without sanforising equipment will face consistent dimensional complaints. There is no chemical shortcut to replacing mechanical pre-shrinkage; enzyme treatments and softeners do not solve the structural problem. - **Water consumption is a genuine liability.** Growing one kilogram of conventional cotton fibre requires 1,500–2,000 litres of water in irrigation-intensive regions (India, Pakistan, Uzbekistan). For brands with ESG reporting requirements or premium consumers focused on sustainability, this is a real reputational risk. Mitigation: GOTS organic certification reduces chemical inputs but not water; BCI certification addresses water use management; Recycled Cotton (GRS-certified) is the most defensible environmental position. - **Pilling on lower-grade constructions.** Open-end spun cotton in Ne 20s–24s single jersey pills visibly after 15–20 wash cycles. This is a specification problem more than a fibre problem — but if you're buying on price from a mill that doesn't disclose spinning method, you will see this in customer reviews. Always specify ring-spun, combed, and request a Martindale pilling test at Grade 3 minimum before bulk production. - **Colour fading in black and deep navy.** Reactive-dyed black cotton at Ne 30s fades to a charcoal-grey tone after 20–25 wash cycles regardless of dye quality. This is a fundamental limitation of reactive dye-cellulose bond stability under repeated mechanical and chemical washing stress. Mitigation through sulphur bottom-reactive top dyeing adds 30–40% to dye processing cost but extends colour life by 30–40%. --- ## Cost Analysis *The economics of Cotton for T-Shirt Manufacturing.* **Yarn Pricing (April 2026, FOB India)** - Ne 20s ring-spun carded: ₹220–260/kg ($2.65–3.10/kg) - Ne 30s ring-spun combed: ₹270–320/kg ($3.25–3.85/kg) - Ne 40s ring-spun combed: ₹320–385/kg ($3.85–4.60/kg) - Ne 30s organic (GOTS-certified): ₹360–420/kg ($4.30–5.00/kg) — 25–35% premium over conventional **Fabric Cost at 180 GSM Single Jersey (Ne 30s, finished, dyed)** - Conventional ring-spun combed: ₹280–340/metre - Organic GOTS-certified: ₹360–430/metre - Yarn consumption at 180 GSM: approximately 0.32–0.38 kg/metre depending on width (150cm cut width) **Cost-Per-Garment Impact (Adult M size t-shirt, ~220g finished)** - Fabric cost (180 GSM, conventional): ₹85–110 - CMT + trims: ₹65–90 - Finishing + packing: ₹20–30 - **Total ex-factory cost: ₹170–230 ($2.05–2.75)** - At 30 GSM step-up to 210 GSM premium construction: add ₹20–30/garment **Cost-Per-Wear Calculation** Assuming a well-manufactured ring-spun combed cotton t-shirt (180 GSM, properly pre-shrunk): - Retail price: ₹799–1,299 - Estimated wearable life: 60–80 wash cycles before visible quality degradation - Cost-per-wear: ₹10–22 per wearing - Compare to promotional open-end carded cotton (₹299 retail): 20–30 wash cycles before unacceptable pilling and dimensional distortion → ₹10–15 per wearing, but customer satisfaction and repeat purchase drops sharply **Comparison vs Alternatives** - Polyester 100% (Ne 30s equivalent): ₹180–220/kg — 30–40% cheaper, but reactive print quality and consumer perception penalty - CVC 60/40 cotton-polyester: ₹230–270/kg — cost-optimised, shrinkage control better than pure cotton, but compromises print vibrancy - Pima/Supima cotton (Ne 40s): ₹580–800/kg — 2–2.5x premium over standard combed, justified only above ₹1,200 retail **ROI for Brand Owners** The return rate differential between a properly finished Ne 30s combed cotton tee and a standard carded open-end tee is typically 3–7 percentage points (industry average: 12–15% returns for mass market cotton vs 6–9% for premium ring-spun). At ₹799 retail and 5,000 units, reducing returns by 5 percentage points saves ₹199,750 in reverse logistics alone — equivalent to upgrading the full production run to ring-spun combed yarn. --- ## Sustainability Profile *Environmental and ethical considerations.* **Water Footprint** Conventional cotton t-shirt manufacturing consumes an estimated 2,700 litres of water per garment across the full supply chain (field to finished product). This is the highest water footprint of any major apparel fibre and the most frequently cited criticism in lifecycle assessments. Indian cotton cultivation in Maharashtra and Gujarat depends heavily on groundwater irrigation, creating supply chain exposure to drought and water stress classifications. **Available Certifications** - **GOTS (Global Organic Textile Standard)**: Covers organic field inputs and processing chain chemicals; requires 95%+ organic fibre content. Premium of ₹80–120/garment in ex-factory cost. - **OEKO-TEX Standard 100**: Covers harmful substance limits in the finished garment — does not address farming practices. Minimum bar for European market entry. - **Better Cotton Initiative (BCI)**: Farm-level water, pesticide, and labour standard — mass balance system, meaning the BCI cotton you buy may not be physically from BCI farms. Widely used by volume brands; increasingly scrutinised by NGOs. - **Recycled Cotton (GRS-certified)**: Uses pre- or post-consumer cotton waste; 40–60% water reduction vs virgin cotton. Quality variability is the main limitation — shorter, weaker staple lengths. - **Fair Trade USA / Fairtrade International**: Covers farmer pricing and community investment; independent of environmental metrics. **Biodegradability** Cotton is 100% biodegradable in natural fibre form. A pure cotton t-shirt in landfill conditions degrades within 1–5 years depending on dye and finishing chemical loadings. Addition of synthetic trims (polyester thread, elastane collar binding) significantly extends decomposition time. **Consumer Perception** Sustainability-conscious consumers in India (primarily urban, 25–40 age bracket) show increasing preference for certified organic cotton, but price elasticity limits remain at approximately 20–30% premium over conventional cotton at retail. European and North American markets are more mature — GOTS or BCI certification is increasingly a market entry requirement for premium retail partnerships, not a differentiator. --- ## FAQ *Cotton for T-Shirt Manufacturing — answered.* **1. What makes ring-spun combed cotton better than carded for t-shirt production?** Combing removes short fibres below 16mm from the cotton sliver, leaving only longer, parallel-aligned staples. Ring-spinning then twists these aligned fibres into a dense, smooth yarn with fewer protruding fibre ends. The practical result: a fabric surface that resists pilling by 35–45% more than carded cotton at equivalent GSM, absorbs screen-print ink more uniformly, and retains hand feel after washing. For any tee retailing above ₹499, ring-spun combed is the minimum specification — not a premium add-on. **2. What's the minimum order quantity for cotton t-shirt fabric from Indian mills?** For greige (undyed) fabric from circular knitting mills in Tiruppur: 500–1,000 metres per construction per roll lot. For dyed and finished fabric: typically 500 metres per colour per construction. Below these thresholds, most mills will add a short-run surcharge of 8–15%. CMT garment manufacturers in Tiruppur will take orders from 200 units per style/colour at standard rates; some boutique units accept 100 units with 10–15% premium on CMT cost. **3. How does cotton t-shirt fabric perform after 30+ wash cycles?** A properly specified and finished ring-spun combed cotton t-shirt (180 GSM, sanforised, reactive dyed) at 30 wash cycles (40°C, domestic machine): colour retention at ISO 105-C06 grade 3.5–4 (slight fade in deep shades, minimal in mid-tones), dimensional change within 3–4% cumulative from original, pilling at Martindale grade 3 (acceptable surface integrity). The key failure modes are shrinkage-related distortion (solved by sanforising) and collar distortion (solved by ribbing tape at collar seam). Unfinished or improperly pre-shrunk fabric shows 8–12% length shrinkage by wash 10, at which point the garment is unwearable. **4. What GSM should I specify for my t-shirt line?** This depends on your positioning and target market: 150–160 GSM for volume promotional tees or summer basics where cost-per-unit is the primary driver; 170–185 GSM for mid-market branded tees where hand feel and shape retention matter; 190–210 GSM for premium branded basics competing on quality feel, typically priced ₹799–1,499 retail; 220–240 GSM for heavyweight tees positioned as seasonal/year-round staples. Do not specify below 160 GSM for a branded product — the fabric transparency and lack of body creates a commodity perception regardless of fibre quality. **5. Is ring-spun cotton suitable for DTG (direct-to-garment) printing?** Yes — it is the preferred substrate. Ring-spun combed cotton's parallel fibre alignment creates a flat surface that accepts inkjet ink penetration uniformly. Recommended specification for DTG: minimum 180 GSM, 100% ring-spun combed cotton, pre-treated (primer applied before printing either at the mill or inline). Blended fabrics with 15%+ polyester show reduced colour saturation and increased wash-fade in DTG prints. Heavier GSM (190–210) provides better ink hold and sharper fine-detail reproduction. **6. What certifications should I look for when sourcing cotton for t-shirts?** At minimum: OEKO-TEX Standard 100 (harmful substances), which is table stakes for any export-oriented or branded production. For sustainability claims: GOTS for organic, BCI for conventional-with-sustainability-commitment, GRS for recycled content. For market-specific requirements: Bluesign is sometimes requested by European outdoor brands; Cradle to Cradle certification is emerging but not yet mainstream in t-shirt supply chains. Request actual certificate numbers, not just claims — OEKO-TEX has a public database where certificate validity can be verified. **7. How does cotton handle high-volume screen printing for promotional tees?** Cotton is the industry standard for high-volume screen printing for valid technical reasons. At 40 mesh screen counts for halftone work and 24–30 mesh for solid flood fills, plastisol and water-based inks both bond reliably to the cotton surface. Key variable: ensure the fabric is pre-shrunk before printing, otherwise garment distortion during curing (dryer temperatures run 150–160°C) will cause print registration drift. For discharge printing (bleach-out base + pigment overdye), cotton is the only viable substrate — polyester cannot be discharged. **8. What's the typical lead time for cotton t-shirt manufacturing in India?** Standard production timeline from approved tech pack: yarn sourcing 1–2 weeks, knitting + finishing 2–3 weeks, cutting + CMT 2–3 weeks, packing + QC 1 week = 6–9 weeks total. Add 1–2 weeks for custom dyeing against a new shade standard. Air freight to major markets adds 3–5 days; sea freight 18–28 days. For repeat orders with approved materials, 4–5 weeks is achievable. Rush production with premium pricing: 3–4 weeks minimum — below this, you are compromising either the pre-shrink protocol or QC inspection. --- ## Related Links **Related Applications** Cotton yarn is also widely used for: [casualwear](/yarn/cotton/casualwear), [loungewear](/yarn/cotton/loungewear), [workwear](/yarn/cotton/workwear), [hoodies-sweatshirts](/yarn/cotton/hoodies-sweatshirts), [polo-shirts](/yarn/cotton/polo-shirts), [underwear-basics](/yarn/cotton/underwear-basics) **Alternative Fibers for T-Shirt Manufacturing** Other fibers used in t-shirt manufacturing: [polyester](/yarn/polyester/t-shirt-manufacturing), [pima-cotton](/yarn/pima-cotton/t-shirt-manufacturing), [organic-cotton](/yarn/organic-cotton/t-shirt-manufacturing), [bamboo](/yarn/bamboo/t-shirt-manufacturing), [tri-blend](/yarn/tri-blend/t-shirt-manufacturing), [viscose](/yarn/viscose/t-shirt-manufacturing), [egyptian-cotton](/yarn/egyptian-cotton/t-shirt-manufacturing), [cotton-poly-blend](/yarn/cotton-poly-blend/t-shirt-manufacturing), [supima-cotton](/yarn/supima-cotton/t-shirt-manufacturing) **Glossary Terms** - [Ring-Spun](/glossary/ring-spun) — spinning method that aligns staple fibres for smoother, stronger yarn - [Combed Cotton](/glossary/combed-cotton) — cotton processed to remove short fibres, improving hand feel and pilling resistance - [GSM](/glossary/gsm) — grams per square metre; the key weight specification for knitted fabrics - [Fabric Weight](/glossary/fabric-weight) — how GSM translates to garment hand feel and end-use category **Compare Page** [Compare Cotton vs alternatives →](/compare/cotton)
