Latest Patents

Niu's latest inventions include two significant patents:

1. **Semi-dull polyester drawn yarns and preparing method thereof** - This invention discloses a type of semi-dull polyester drawn yarns. The preparation method involves melt spinning a modified polyester using the FDY technique. The modified polyester is created through the esterification and subsequent polycondensation reactions of a precise mixture of terephthalic acid, ethylene glycol, main chain silicated diol, fluorinated dicarboxylic acid, matting agent, and doped BiO. The yarn produced boasts a dye uptake of 87.5-91.8% when dyed at 120°C, with a notable intrinsic viscosity drop upon storage conditions of 25°C and 65% R.H. over 60 months. This innovation emphasizes ease of application while presenting a product with commendable dyeing and degradation performance.

2. **Porous ultra-soft ultra-fine denier polyester fiber and its preparation method** - This patent outlines the creation of a porous ultra-soft ultra-fine denier polyester fiber. The method entails using a porous spinneret that has elliptical arrangements of holes to spin modified polyester, which is processed through metering, extruding, cooling, oiling, and high-speed winding. This fiber is characterized by exceptional properties, which include a deviation rate of fiber density of ≤0.5%, a CV value of breaking strength of ≤4.0%, a CV value of elongation at break of ≤8.0%, and a CV value of yarn unevenness of ≤2.0%.
