The characteristics of underwear fabrics are fit and portable, elastic, comfortable, easy to exercise, good flexibility, good moisture absorption and air permeability, and good anti-wrinkle performance, but the fabric is easy to fall off, poor dimensional stability, easy to snag, fuzz and pilling. Varieties include flat stitches, mesh fabrics, double ribs, single ribs, and fleece. The outerwear fabric is characterized by strong wear resistance, low shrinkage, easy to wash, and full of elasticity.
2. According to the production process classification

This is because one yarn can only form one loop. The Lian-like thing. Warp-knitted fabric has the advantages of good longitudinal dimensional stability, stiff fabric, low dispersibility, no curling, and good air permeability, but its horizontal extension, elasticity and softness are not as good as weft knitted fabrics.
3. According to the production materials classification
1) Polyester yarn-dyed knitted fabric
The polyester yarn-dyed knitted fabric is made of dyed low-elastic polyester yarn, which is configured in different colors according to the design requirements, and the jacquard weave is woven into 3-6 colors or even more color patterns.
