High-modulus low-shrinkage polyester industrial yarn and its preparation method
A high-modulus low-shrinkage polyester industrial yarn obtained by subjecting a polyester to dissolution, washing and solid state polycondensation followed by spinning. The high-modulus low-shrinkage polyester industrial yarn has a dry heat shrinkage rate of 2.0±0.25% under test conditions of 177° C.×10 min×0.05 cN/dtex. The average value of the crystal volume Vc of the high-modulus low-shrinkage polyester industrial yarn is larger than 230 nm3. The high-modulus low-shrinkage polyester industrial yarn has a fiber modulus of ≥100 cN/dtex. The polycondensation catalyst consists of magnesium ethylene glycol and antimony ethylene glycol, which has a small thermal degradation coefficient.
