| titleOfInvention | Polyester directly-spun short fiber for hydrolysis-resistant and photoaging-resistant industry and preparation method thereof |
| abstract | The invention discloses a polyester directly-spun short fiber for hydrolysis-resistant and photoaging-resistant industry. The polyester directly-spun short fiber is prepared from PET polyester through a direct spinning process, an ultraviolet absorbing agent accounting for 0.02-0.03% of weight of polyester, a terminated-base hydrolysis-resistant ionomer accounting for 0.8-1.2% of the weight of polyester and barium sulfate accounting for 0.08-0.12% of the weight of polyester are added into the process of direct spinning, and intrinsic viscosity of PET polyester melt is 0.68-0.74dl/g. The invention further discloses a preparation method of the polyester directly-spun short fiber. The ultraviolet absorbing agent and the terminated-base hydrolysis-resistant ionomer are added in the process of production, and relative high-temperature heat setting is adopted, so that the short fiber is resistant to hydrolysis, intrinsic viscosity drop of the short fiber is smaller than or equal to 0.03dl/g, the short fiber is resistant to photoaging, and breaking strength retention rate of the fiber after quickly aging due to ultraviolet irradiation is greater than or equal to 90%. |
