| titleOfInvention | Wool-like polyester filament and its manufacturing method |
| abstract | An object of the present invention is to provide a wool-like polyester filament and a method for producing the same. The method for producing wool-like polyester filaments is terephthalic acid, 1,4-butanediol, fluorine-containing dicarboxylic acid, hexanediol having tert-butyl, and 2,5,6,6-tetramethyl-2,5-heptanediol. Is uniformly mixed and further esterified, and the melt of the modified polyester to be polycondensed is made into a fiber by a method of semi-drawn yarn (Partially Oriented Yarn, POY) and drawn processed yarn (Draw Textured Yarn, DTY). That is. The obtained fibers had a dyeing rate of 90.32 to 93.27% at a dyeing temperature of 100 ° C., a dyeing performance of K / S value of 22.15 to 23.42, and a relative humidity of 25 ° C. and 65%. After being placed underneath for 60 months, it has a natural decomposition performance of 18 to 25% of the intrinsic viscosity drop. The method provided in the present invention is inexpensive and convenient to operate, and the provided product has good dyeing performance and fast natural decomposition, so that it has a wide range of uses.
