Abstract

The invention relates to a super-soft superfine polyester fiber and a preparation method thereof. The super-soft superfine polyester fiber is mainly prepared by the steps of melt spinning of polyester through spinneret holes, application of an oiling agent and high-speed winding, wherein the oiling agent at least comprises fluorine-containing polyether, the mass of which is more than or equal to 45% of that of the oiling agent, the fluorine-containing polyether is a random copolymer of ethylene oxide, [(1,1,2,2-tetrafluoroethoxy) methyl] oxirane and propylene oxide, and the structural formula of the random copolymer is shown in the specification. The preparation method comprises the steps of metering, extruding, cooling, oiling, stretching, heat setting and high-speed winding of polyester, thereby obtaining the super-soft superfine polyester fiber. As the filament fineness of the super-soft superfine polyester fiber is very high, a fabric has advantages of specially soft and fine hand feeling, soft luster, comfortableness, breathability and good appearance texture and is easy to care, thus being popular with users more and more.

Description

technical field [0001] The invention relates to a supersoft and superfine polyester fiber and a preparation method thereof. Background technique [0002] Since its appearance, polyethylene terephthalate (PET) fiber has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fibers in the world. Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance, and the fabric has the advantages of wrinkle resistance and good stiffness, so , Polyester fibers are 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 22dte...
