Embodiment 1

[0015] 10kg of polyester chips (ethylene terephthalate fibers) are heated to a molten state, and then 0.5kg of far-infrared negative ion nano-functional slurry is added for blending and granulation to obtain a masterbatch, and the masterbatch is wet-spun, and the spinning The silk is washed, dried, and wound up at a speed of 50 m / min to obtain functional polyester fibers 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 ultrasonically dispersing to obtain a nano-titanium dioxide / nanometer 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 obtain a composite powder. The particle size of the composite powder is about 10 μm; , mixing the composite pow...

Embodiment 2

[0018] 10kg polyester chip (ethylene terephthalate fiber) is heated to molten state, then adds the nano functional slurry blending granulation of 0.75kg far-infrared anion to obtain masterbatch, masterbatch is carried out wet spinning, to Spinning is carried out cleaning, drying, winding, and the winding speed is 80m / min, obtains the functional polyester fiber containing far infrared and negative ions.

[0019] Wherein, the far-infrared negative ion nano-functional slurry is prepared by the following method: 10 parts of nano-titanium dioxide and 10 parts of nano-zinc oxide are added to 30 parts of ethanol solvent, and ultrasonically dispersed to obtain a nano-titanium dioxide / nanometer zinc oxide dispersion; 30 parts of infrared ceramic powder, 35 parts of tourmaline powder and 15 parts of hydroxymethyl cellulose ether are placed in a sand mill and mixed to obtain a composite powder. The particle size of the composite powder is about 20 μm; , mixing the composite powder with n...

Embodiment 3

[0021] 10kg of polyester chips (ethylene terephthalate fibers) are heated to a molten state, then 1kg of far-infrared negative ion nano-functional slurry is added to blend and granulate to obtain a masterbatch, and the masterbatch is wet-spun, and the spinning Carry out cleaning, drying, winding, and winding speed is 100m / min, obtains far-infrared anion function polyester fiber.

[0022] Wherein, the far-infrared negative ion nano-functional slurry is prepared by the following method: adding 15 parts of nano-titanium dioxide and 15 parts of nano-zinc oxide to 25 parts of ethanol solvent, and ultrasonically dispersing to obtain a nano-titanium dioxide / nanometer zinc oxide dispersion; 35 parts of infrared ceramic powder, 30 parts of tourmaline powder and 20 parts of hydroxymethyl cellulose ether are placed in a sand mill and mixed to obtain a composite powder. The particle size of the composite powder is about 30 μm; , mixing the composite powder with nano-titanium dioxide / nano-...

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...
