Technical Specs That Define a World-Class T-Shirt Manufacturing from Tirupur
Global buyers are increasingly demanding when it comes to T-shirts. Beyond aesthetics, every export-grade tee must withstand lab tests, retail shelf life, and consumer expectations. Here are the key technical parameters:
1. Fabric Selection & Durability
Cotton (Combed, Ringspun, Compact) – soft hand feel, reduced pilling, long-lasting. Perfect for premium basics.
Organic Cotton (GOTS Certified) – eco-conscious, pesticide-free, favored by EU and US sustainable fashion brands.
Poly-Cotton Blends – durability and wrinkle resistance for corporate, promotional, and budget-friendly tees.
Bamboo & Modal – luxurious drape, natural antibacterial properties, moisture-wicking.
Poly-Spandex / Performance Blends – stretch, recovery, sweat absorption—ideal for activewear.
Durability is validated through tensile strength, bursting strength, and abrasion resistance tests as per ISO and ASTM standards.
2. GSM & Knit Structures
Lightweight tees: 140–160 GSM (youth, promotional).
Standard retail tees: 160–180 GSM (everyday fashion).
Premium/oversized streetwear: 200–240 GSM (structured fit).
Knits: Single jersey, interlock, pique, and slub depending on brand requirements.
3. Stitching & Construction
A T-shirt’s longevity depends on how it’s put together. Export-grade tees from Tirupur adhere to international benchmarks:
Hems: Cover-stitch or double-needle hems for stretch and durability.
Side Seams vs Tubular: Side-seamed ensures better shape retention, tubular is economical.
Shoulder Reinforcement: Taped seams to prevent distortion and bagging.
Neck Rib Composition: Cotton/spandex blends for recovery and shape retention.
Seam Allowance & Tolerances: Maintained as per buyer’s spec sheet to avoid size inconsistencies.
Global Lab Standards & Certifications

OEKO-TEX® Standard 100 – ensures fabrics are free from harmful chemicals.
GOTS (Global Organic Textile Standard) – mandatory for organic cotton exports to Europe/USA.
