Tirupur, India, is recognized globally as a premier hub for the manufacturing of T-shirts, hoodies, and high-quality children’s clothing. The foundation of this reputation lies in the region’s diverse access to various knitting yarns. At Synerg, we believe that the soul of a garment is determined by its fiber; choosing the right yarn is the first step in ensuring your brand meets its quality and sustainability goals.
This guide details the specific yarn types utilized by leading T-shirt manufacturers in India to help you make informed sourcing decisions.
1. The Cotton Standards: Combed vs. Carded
Cotton remains the most sought-after material for knitwear, but the processing method changes the final garment’s value significantly:
- Carded Cotton: The basic form of cotton yarn. It is less refined than combed versions but remains popular for budget-friendly apparel lines.
- Combed Cotton: This yarn is processed to remove impurities and short fibers. The result is a stronger, smoother, and more lustrous fabric.
- Super Combed Cotton: An even more refined grade that offers superior softness and durability. This is the benchmark for premium T-shirt collections.
2. High-End Specialty Cotton
For brands targeting the luxury or high-performance retail segment, long-staple cotton is often the required standard:
- Pima Cotton: Known for its extra-long staple fibers, Pima provides a luxurious hand-feel and exceptional durability.
- Egyptian Cotton: Renowned for premium quality and strength, similar to Pima, and highly valued in high-end fashion.
- Supima Cotton: A superior American-grown cotton known for its incredible softness and high color retention.
Because Pima cotton is prized for its luster and strength, it is often compared to treated yarns to achieve a high-end finish. If you are aiming for a luxury look, it is helpful to understand the differences between mercerized and unmercerized cotton to decide if your Pima T-shirt requires additional chemical processing or if the natural fiber strength is sufficient.
3. Certified Organic & Sustainable Yarns
Sustainability is no longer a niche; it is a 2026 requirement for global fashion brands:
- NPOP & GOTS Cotton: Organic cotton grown without synthetic fertilizers or pesticides. In India, NPOP ensures the crop meets national organic standards.
- BCI Cotton: Certified by the Better Cotton Initiative, supporting sustainable farming and farmer welfare.
- Recycled Polyester (rPET): Made from recycled PET bottles, this yarn provides performance-level strength with a lower environmental footprint.
4. High-Performance Blends
Blended yarns combine the comfort of natural fibers with the technical advantages of synthetics:
- Cotton-Spandex (Lycra): Typically a 95/5 blend. These yarns are essential for fitted T-shirts and activewear requiring high stretch.
- Cotton-Polyester: A durable blend that offers moisture-wicking properties, ideal for performance-driven tees.
- Performance Blends: Specialized yarns treated with antimicrobial finishes to fight odor during intense activity.
5. Viscose and Botanical Fibers
These yarns are favored for their incredible drape and “silky” texture:
- Bamboo Viscose: Soft, breathable, and naturally antibacterial—a favorite for eco-conscious loungewear.
- Modal: A high-strength fiber made from beechwood pulp, often blended with cotton to increase softness.
- Tencel / Lyocell: A sustainable wood-pulp fiber known for being environmentally friendly and exceptionally smooth.
6. Aesthetic & Fashion-Driven Yarns
To create visual interest without complex printing, manufacturers use specialized spinning techniques:
- Melange Cotton: Fibers are dyed before being spun together, creating a beautiful heathered or multi-tonal effect.
- Slub Yarn: Created with intentional thick and thin sections to give the finished T-shirt a textured, vintage look.
7. Budget-Friendly Solutions
For high-volume promotional orders, secondary yarn types are often utilized:
- Recycled Cotton-Poly Blends: Promotes circular fashion by reusing fibers to reduce waste.
- Open-End (OE) Yarn: A fast-produced yarn often used for mass-market, budget-conscious apparel.
⚠️ Karthik’s Take: The OE Yarn Warning
In the manufacturing hub of Tirupur, a major issue I frequently see is the mislabeling of Open-End (OE) yarn. Many suppliers will claim OE yarn is “100% Cotton,” but in reality, it is almost always a blend mixed with polyester to give it enough strength for the machine.
Most international buyers are unaware of this distinction. OE yarn is significantly coarser, less durable, and will not have the same breathability as true combed cotton. At Synerg, we maintain radical transparency: we only use 100% Ring Spun Combed cotton when our buyers ask for pure cotton. Always verify your yarn source to ensure you aren’t accidentally selling a poly-blend as pure cotton.
