Abstract

The invention relates to a preparation method of a functionalized polyester fiber. The functionalized polyester fiber is prepared through blended spinning of functional powder coated by polyester chips and polybutylece terephthalate (PBT). A preparation method of the functional powder coated by the PBT includes that a layer of titanium catalysts is supported on the surface of the functional powder, added polybutylece terephthalate cyclic oligomer (CBT) polymerizes on the surface of the functional powder and generates PBT resin under the action of the catalysts, and the functional powder coated by the PBT is obtained after spray powdering. The catalysts for the polymerization of the CBT are supported on the surface of the functional powder through a supporting technology, the mass ratio of the PBT resin to the functional powder is (2-4):1, the mass ratio of the polyester chips to the functional powder coated by the PBT is (10-15):1, the functional powder coated by the PBT has a good compatibility with polyester, and the functionalized effects of the obtained functionalized polyester fiber are excellent.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a preparation method of functionalized polyester fibers. Background technique [0002] With the continuous development of the fiber industry, people's requirements for fibers are not limited to the functions of covering the body and beauty in the past, but more focus on realizing the functionalization and diversified use of fibers. At present, the functional modification of various synthetic fibers including polyester fiber and polyamide fiber has made great progress. The main functional means include chemical grafting of fibers, blend spinning and fabric modification. Finishing method, etc., wherein the functionalization of fibers by blend spinning method is the easiest and most effective means, and the functionalization effect of the obtained fibers is also relatively long-lasting. Most of the functional powders used in the fiber functionalization process are inorganic mate...
