When Southeast Asian manufacturers consider sell on alibaba.com opportunities in the apparel sector, understanding knitted fabric specifications becomes the critical differentiator between winning and losing orders. Unlike woven fabrics that use interlaced warp and weft threads, knitted fabrics are constructed from interlocking loops of yarn—creating the signature stretch, drape, and breathability that makes them ideal for T-shirts.
For B2B buyers sourcing men's knit T-shirts, the conversation typically starts with three fundamental questions: What's the GSM? What's the fiber composition? And what's the MOQ? These aren't arbitrary specifications—they're the language of trust in international textile trade.
Knitted vs. Woven Fabric: Key Differences for T-Shirt Applications
| Attribute | Knitted Fabric | Woven Fabric | T-Shirt Suitability |
|---|---|---|---|
| Construction Method | Interlocking loops of yarn | Interlaced warp and weft threads | Knitted preferred for T-shirts |
| Stretch & Recovery | High elasticity, natural stretch | Limited stretch unless blended with elastane | Knitted offers superior comfort |
| Breathability | Excellent air circulation between loops | Variable, depends on weave density | Knitted excels in warm climates |
| Drape & Softness | Soft, conforms to body shape | Structured, holds shape rigidly | Knitted ideal for casual wear |
| Production Speed | Faster knitting processes, lower labor cost | Slower weaving, higher precision | Knitted more cost-effective for volume |
| Typical GSM Range | 120-180 gsm for T-shirts | 150-250+ gsm for shirts | 120-180 gsm optimal for T-shirts |
| Common Applications | T-shirts, underwear, sportswear, loungewear | Dress shirts, trousers, jackets | Knitted dominates casual apparel |
GSM (Grams per Square Meter) deserves special attention because it's the single most misunderstood specification in cross-border T-shirt trade. GSM measures fabric weight, not thickness—though they correlate. A 120 gsm jersey feels lightweight and breezy, perfect for tropical Southeast Asian markets and summer collections. A 180 gsm fabric feels substantial and premium, commanding higher prices in European and North American markets where consumers associate weight with quality.
The sweet spot for year-round men's T-shirts? 150-160 gsm. This range offers enough substance to avoid transparency issues while maintaining breathability for warm weather wear. Anything below 130 gsm risks appearing cheap; anything above 170 gsm may feel too heavy for casual T-shirt applications.
