preparation example 1

[0036] Preparation Example 1: Preparation of Modified Coffee Charcoal

[0037] (1) In parts by weight, first weigh 0.5 parts of zinc chloride and dissolve in 100 parts of water to obtain a zinc chloride solution, take 40 parts of coffee grounds, wash them with distilled water, and dry them, then add them to the zinc chloride solution The dried coffee grounds are stirred evenly. The coffee grounds are soaked in zinc chloride solution for 1 hour, then filtered, and the filter residues are taken. Dry the obtained filter residues in a sintering furnace at 100°C for 2 hours, and then heat up to 900-1000°C Calcining at ℃ for 1-2 hours, grinding the calcined coffee grounds into powder, passing through a 1000-mesh sieve to obtain coffee charcoal powder;

[0038] (2) In parts by weight, 8 parts of silver nitrate are dissolved in 100 parts of water to obtain a silver nitrate solution, and the coffee charcoal powder obtained in the above step (1) is added into the silver nitrate solution...

[0039] Preparation example 2: Preparation of auxiliary antibacterial agent

[0040] In parts by weight, take 10 parts of tea leaves and 10 parts of bitter wood, grind them into powder, add the obtained powder into 100 parts of ethanol solution, stir at 60°C for 3h, filter, take the filtrate, and Rotary evaporation was carried out under the conditions, and the ethanol solvent was volatilized to obtain the auxiliary antibacterial agent. The obtained auxiliary antibacterial agent mainly contains components such as tea polyphenols, catechins, flavonoids, antibacterial alkaloids and the like.

Embodiment 1

[0042]① In parts by weight, weigh 4 parts of modified coffee charcoal powder, 3 parts of auxiliary antibacterial agent, 1 part of nano-titanium dioxide, the average particle size of nano-titanium dioxide is 10-20nm, 6 parts of a mixture of wood wax oil and polyoxyethylene , wherein the weight ratio of wood wax oil and polyoxyethylene is 1: 1, and the average molecular weight of polyoxyethylene is 300, above-mentioned material is mixed uniformly by mixer, obtains mixture, weighs 80 parts of PET chips again, Add it into the above-mentioned mixture, and continue to mix and stir to obtain a masterbatch.

[0043] ②Melt extrude and granulate the masterbatch obtained above through a twin-screw extruder at a temperature of 210-265°C. The length-to-diameter ratio of the screws is 40:1 to obtain an antibacterial polyester masterbatch, and then the obtained antibacterial polyester The polyester masterbatch is spun by the melt spinning method, the melt spinning temperature is 280-285°C, t...

Abstract

The invention particularly discloses antibacterial polyester fiber and a preparation method and application thereof. The raw materials of the antibacterial polyester fiber comprise the following components including, by weight, 80-90 parts of PET slices, 4-12 parts of modified coffee carbon powder, 3-8 parts of an auxiliary antibacterial agent, 1-5 parts of nanometer titanium dioxide, 6-12 parts of a mixture including wax oil and polyoxyethylene and 0.5-1.5 parts of dodecyl dimethyl betaine, wherein the auxiliary antibacterial agent is extracts from tea leaves and quassia, and the coffee carbon powder is obtained by modifying silver nano particles. The preparation method comprises the steps that the mixture of the modified coffee carbon powder, the auxiliary antibacterial agent, the nanometer titanium dioxide, the wax oil and the polyoxyethylene, and the dodecyl dimethyl betaine are mixed, a mixture is obtained, and then the PET slices and the mixture are mixed to obtain master batch;and the obtained master batch is subjected to melt extrusion and pelleting to obtain antibacterial polyester master batch, then the antibacterial polyester master batch is subjected to melt spinning,and the antibacterial polyester fiber is obtained. The polyester fiber provided by the invention have the effects of good and durable antibacterial property.

Description

technical field [0001] This application relates to the technical field of clothing fabrics, more specifically, it relates to an antibacterial polyester fiber and its preparation method and application. Background technique [0002] Polyester fiber is an important variety of synthetic fibers. It is a fiber made of PET polyester through spinning; the fabric woven from polyester fiber filament has good strength, good elasticity, not easy to deform, corrosion resistance, insulation, slippery Cool and crisp and other excellent performance, loved by people. Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. In order to meet people's requirements for the functionalization of textiles and the world's textile industry's demand for polyester, the industry has continued to invest in research on modified polyester and strengthen the development of modified polyester. Therefore, various functional modified polyesters are constan...
