Bright warm-keeping lightness type fibers and preparation method thereof

Abstract

The present invention relates to bright warm-keeping lightness type fibers and a preparation method thereof, wherein mainly a polyester is subjected to special-shaped spinning hole melt spinning, oil agent feeding and winding so as to prepare the bright warm-keeping lightness type fibers, wherein the oil agent at least comprises a fluorine-containing polyether, the mass of the fluorine-containing polyether is more than or equal to 45% of the mass of the oil agent, the fluorine-containing polyether is a random copolymer of ethylene oxide, [(1,1,2,2-tetrafluoroethoxy)methyl]ethylene oxide and propylene oxide, and the structure formula is defined in the specification. The preparation method comprises: metering a polyester, extruding, cooling, oiling, stretching, carrying out thermal shaping, and winding so as to prepare the bright warm-keeping lightness type fibers. According to the bright warm-keeping lightness type fibers of the present invention, the fiber cross section shape is changed by the spinning while the fibers have the hollowness, the air permeability and the thermal insulation property are increased, and with the special cross section shape of the fibers, the bright surface light refraction effect is provided so as to make the fabric bright and gorgeous; and the fibers further have characteristics of lightness, light weight, and soft touch feeling.

Description

technical field

[0001] The invention relates to a bright, warm and light 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] A bright, warm and light fiber, which is a bright special-shaped yarn, changes the cross-sectional shape of the fiber through spinning, and at the same time makes the fiber hollow to increase air permeability and thermal insulation....
