Microfiber yarn is a non-polluting high-tech new textile material, and it’s composition is a kind of superfine microfiber produced by the organic compound of polyester and polyamide. Because it is a kind of material with remarkable functions such as strong water absorption, good air permeability, mildew resistance (antibacterial after special processing), it is currently being widely used in the weaving of clothing and home textiles. The polyester-polyamide composite yarn is a standard 8020 high-quality yarn with a fineness of only 0.2 denier and extremely tough (only 1/200~300 of the hair, 1 gram of microfiber yarn can be stretched to 90000 meters without breaking).
