Abstract

The invention discloses an enhanced type polyester staple fiber. The enhanced type polyester staple fiber is prepared by the following steps of using waste plastic PET (polyethylene terephthalate) andPET foam as the main materials of polyester fiber, and mixing with third monomers of isophthalic acid, polycarbonate and phosphorus-containing halogen-free flame-retardant master batch; sucking vacuum, and drying, so as to obtain a slurry; adding silver nitrate, sodium chloride, quaternary ammonium salt, modified water-soluble epoxy resin emulsion and a distyrene biphenyl sodium disulfate whitening agent to perform esterification reaction on the slurry, so as to improve the antibacterial, anti-mite and whitening effects of the polyester staple fiber; adding a filler powder consisting of nanometer molybdenum dioxide, nanometer magnesium hydroxide, nanometer aluminum hydroxide, pearls, organosilicone and coffee carbon into the slurry, so as to enhance the tensile strength, flame-retardant rate and anti-static effect of the polyester staple fiber, and reach the negative ion-emitting and anti-ultraviolet effects. A textile product produced by the polyester staple fiber is more beneficialto the health of a user.

Description

technical field [0001] The invention relates to a reinforced polyester staple fiber and a preparation method thereof. Background technique [0002] Polyester staple fiber is an important textile raw material with many excellent properties and is widely used in clothing, decoration and other industrial fields. [0003] However, the macromolecule of polyester fiber is an organic compound with a covalent chain as the main chain. It cannot be ionized, nor can it transmit electrons or ions. In addition, its molecular group has very small polarity and high hydrophobicity, and its volume specific resistance reaches 1014-1015Ω·cm, once static electricity is generated by friction, the charge is not easy to dissipate, and the discharge of static electricity is very slow, causing charge accumulation. Therefore, polyester is the fiber that is most likely to generate static electricity, so the garments made of polyester staple fiber are prone to static electricity. cause greater harm to...
