Description

Technical Field

[0001] The invention belongs to the technical field of down jacket fabrics, and particularly relates to an anti-mite down jacket fabric and a processing method thereof. Background Art

[0002] The main components of down in down jackets are fat and protein, and mites rely on fat and protein to survive. Therefore, down jackets are easily nourished by mites after being worn for a long time. In order to solve this problem, the fabrics used to sew down jackets generally use fabrics with anti-mite and anti-mite effects, and the fabrics generally achieve the anti-mite and anti-mite effects through chemical means.

[0003] In the prior art, down jacket fabrics are mostly treated with anti-mite and anti-mite finishing agents or anti-mite and anti-bacterial finishing agents, specifically by padding, dipping, coating and spraying. The disadvantages are: first, the durability is poor. After multiple wearing and washing, the film layer formed by the finishing agent on the fiber surface is prone to failure or significant loss, thereby reducing the anti-mite and anti-bacterial effects; second, the finishing agent has a large amount of chemical agents added, which is more irritating to the skin and even toxic, thus causing safety problems. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-mite down jacket fabric and a processing method thereof in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An anti-mite down jacket fabric comprises an inner layer and an outer layer hot-pressed and laminated on the inner layer, wherein the outer layer is a plain fabric woven from cotton fiber, modified viscose fiber and polylactic acid fiber;

[0007] The modified viscose fiber is prepared by mixing camel thorn alkaline essential oil and a thickener into viscose, and then heating, stirring, ultrasonically dispersing and degassing the viscose mixture through a wet spinning process.

[0008] As a further optimization scheme of the present invention, the outer layer includes, by weight, 20 to 30 parts of cotton fiber, 20 to 35 parts of modified viscose fiber, and 40 to 55 parts of polylactic acid fiber.

[0009] As a further optimization scheme of the present invention, the modified viscose fiber comprises, by mass percentage, 70-80 wt % of viscose fiber, 12-20 wt % of camel thorn alkaline essential oil and 8-16 wt % of thickener.

[0010] As a further optimization scheme of the present invention, the preparation method of the modified viscose fiber is specifically as follows:

[0011] S1. Preheat and mix camel thorn alkaline essential oil and thickener, then add them into the filtered and aged viscose at a uniform speed. During the adding process, heating and heat preservation are required and continuous stirring is required;

[0012] S2, subjecting the viscose treated in step S1 to ultrasonic dispersion treatment, and then subjecting the viscose to degassing treatment to obtain a viscose mixture, and preparing the viscose mixture through a wet spinning process to obtain modified viscose fibers.

[0013] As a further optimization scheme of the present invention, in step S1, the camel thorn alkaline essential oil is obtained by extracting camel thorn powder with 8% sodium hydroxide solution as an extractant, wherein the mass ratio of sodium hydroxide solution to camel thorn powder is 7:1.

[0014] As a further optimization scheme of the present invention, in step S1, the thickener is one of soluble starch, methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl methyl cellulose.

[0015] As a further optimization scheme of the present invention, in step S1, the preheating temperature is 30-40°C, the time used to add camel thorn alkaline essential oil and thickener is 30-45 minutes, the heating and insulation temperature is 125-155°C, and the stirring speed is 1200-1500 r / min.

[0016] As a further optimization scheme of the present invention, in step S2, the vibration frequency of the ultrasonic dispersion is 80-120 kHz.

[0017] A method for processing anti-mite down jacket fabric, specifically comprising:

[0018] Modified viscose fiber, cotton fiber and polylactic acid fiber are blended to obtain warp and weft threads, which are then woven into a plain fabric. The plain fabric is subjected to heat pressing and shaping treatment using a hot pressing roller at 170-185°C, and the outer layer is obtained after natural cooling. The outer layer and the inner layer are compounded to obtain anti-mite down jacket fabric.

[0019] As a further optimization solution of the present invention, the warp density is 70 strands / cm, and the weft density is 65 strands / cm.

[0020] The beneficial effects of the present invention are:

[0021] 1) The present invention adds camel thorn alkaline essential oil in the preparation of modified viscose fiber. The camel thorn alkaline essential oil has a strong antibacterial effect on Escherichia coli, Staphylococcus aureus, and Candida albicans. The camel thorn alkaline essential oil has a strong inhibitory effect on the reproduction of mites and can also drive away mites. Therefore, the anti-mite down jacket fabric woven from it can maintain its anti-mite and anti-bacterial effect for a long time and can improve the wrinkle resistance of the anti-mite down jacket fabric;

[0022] 2) The camel thorn alkaline essential oil in the present invention is obtained by extracting natural plants through sodium hydroxide solution, and then added into the preparation of modified viscose fiber, so it has good durability, natural ingredients, less harmfulness to human body, and is safer;

[0023] 3) After the polylactic acid fiber in the present invention is hot-pressed by a hot-pressing roller and cooled, the gaps between the warp and weft lines can be reduced, thereby making the anti-mite down jacket fabric tighter and also achieving a certain anti-mite effect.
