Example Embodiment

[0014] Example 1

[0015] Heat 10kg of polyester chips (ethylene terephthalate fiber) to a molten state, then add 0.5kg of far-infrared anion nano-functional slurry to blend and granulate to obtain a masterbatch. The masterbatch is wet-spinned and spun The silk is washed, dried, and wound at a winding speed of 50m / min to obtain a functional polyester fiber containing far infrared and negative ions.

[0016] Among them, the far-infrared negative ion nano-functional slurry is prepared by the following method: adding 5 parts of nano-titanium dioxide and 5 parts of nano-zinc oxide to 20 parts of ethanol solvent and ultrasonic dispersion to prepare nano-titanium dioxide / nano-zinc oxide dispersion; 20 parts of infrared ceramic powder, 20 parts of tourmaline powder, and 10 parts of hydroxymethyl cellulose ether are placed in a sand mill and mixed to prepare a composite powder. The particle size of the composite powder is about 10 μm; under stirring conditions , The composite powder is mi...

Abstract

The invention belongs to the technical field of a textile material, and particularly relates to modified polyester fiber and a preparation method thereof. The polyester fiber is prepared from the following materials in percentage by weight: 90 to 95% of polyester chips and 5 to 10% of far infrared anion nano functional slurry, wherein the far infrared anion nano functional slurry is prepared from the following materials in parts by mass: 5 to 15 parts of nano titania, 5 to 15 parts of nano zinc oxide, 20 to 30 parts of ethyl alcohol, 20 to 35 parts of far infrared ceramic powder, 20 to 35 parts of tourmaline powder and 10 to 20 parts of hydroxymethyl cellulose ether. The modified polyester fibers prepared by the formula and the preparation method which are provided by the invention are developed for meeting the requirement of people for high-end textures; the obtained polyester fiber has functions of good far infrared effect, anion physiotherapy, excellent antibacterial property, heat insulation, ultraviolet resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a modified polyester fiber and a preparation method thereof. Background technique [0002] Existing textile materials are divided into many types, and the more commonly used ones are mostly cotton and various chemical synthetic fibers. Through the use of various fibers, the fabric has the functions of warmth retention, good hand feeling, and strong water absorption, and even special fibers are used to make the fabric Fabrics have special properties such as physiotherapy, antibacterial, and even bulletproof for military use. However, existing various textile materials have more or less performance defects when their advantages are exhibited, such as cotton has good thermal insulation effect and strong water absorption, but is prone to mildew and poor acid resistance, and its fabric is fluffy and bloated; hemp fiber Comfortable to wear but rough in appearance...
