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 present invention relates to a bright, warm-keeping and lightweight fiber and a preparation method thereof. Background technique [0002] Since its inception, polyethylene terephthalate (PET) fiber has developed rapidly because of its excellent properties, and its output has become the world's largest 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 fibers are widely used in clothing, home textiles and other fields. [0003] A bright, warm, lightweight fiber, which is a kind of bright special-shaped yarn. The cross-sectional shape of the fiber is changed by spinning, and the fiber has a hollowness to increase air permeability and heat preservation. In additio...
