Knit fabric is a flexible textile created by interlocking loops of yarn through knitting, offering high stretch, breathability, and elasticity ideal for underwear, homewear, and sportswear. Jersey knit (single-knit) provides one smooth side with 4-way stretch for activewear, while interlock knit (double-knit) delivers smoother both sides, density, and pill resistance for underwear. Sino Finetex optimizes these via patented fabrics and full supply chain control.
