Abstract

The present invention relates to a kind of ultra-soft and ultra-fine polyester fiber and its preparation method. The super-soft and ultra-fine polyester fiber is mainly prepared by melt-spinning polyester through spinneret holes, oiling agent and high-speed winding; the above The oil agent of the oil agent includes at least fluorine-containing polyether, and the quality of the fluorine-containing polyether ≥ 45% of the quality of the oil agent; the fluorine-containing polyether is ethylene oxide, [(1,1,2,2 ‑Tetrafluoroethoxy) methyl] random copolymer of oxirane and propylene oxide, its structural formula is: the preparation method of the present invention is that polyester is measured, extruded, cooled, oiled, stretched , heat setting and high-speed winding to produce ultra-soft and ultra-fine polyester fibers. The ultra-soft and ultra-fine polyester fiber of the present invention, because its monofilament fineness is very fine, its fabric has the advantages of particularly soft and delicate hand feeling, soft luster, comfortable and breathable, easy to care and good texture of appearance, and has been increasingly obtained. users' favor.

Description

Technical field [0001] The invention relates to a super soft and super fine polyester fiber and a preparation method thereof. Background technique [0002] Since the advent of polyethylene terephthalate (PET) fiber, it has developed rapidly due to its excellent properties, and its output has become the world's top synthetic fiber. Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat and light resistance, acid and alkali resistance and corrosion resistance, and the fabric has the advantages of wrinkle resistance and good stiffness, so , Polyester fiber is widely used in clothing, home textiles and other fields. [0003] With the rapid expansion of polyester production capacity and changes in the international situation, people have higher requirements for the comfort, functionality, diversification and safety of clothing. Polyester 22dtex / 48f, 22dtex / 72f, 33dtex / 72f and other ...
