1.Look at longitude and latitude

Knitting polyester yarn fabrics include yarn Knitting fabrics and weft Knitting fabrics.Although both of them have been heat-setting or resin treatment, their elongation and other properties are still different.Therefore, weft Knitting fabrics should be selected for different styles of clothing, because weft Knitting fabrics are often Knitting with various colored yarns or medicinal yarns, with various patterns, which are especially suitable for making exquisite women's jackets of different styles; warp Knitting fabrics should be selected for jackets, such as trousers and skirts.Knitting polyester warp Knitting fabrics are suitable for pants and skirts because of their neat appearance, compact structure, good wear resistance, less fuzzing, pilling and crochet, and worse appearance fullness, elasticity and aesthetics than weft Knitting fabrics.

 2.Look at grades
