Description

Technical Field

[0001] The present invention relates to the technical field of the textile industry, and particularly to a textile fabric with regenerated cellulose fibers. Background Art

[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and the performance effect of the shape of clothing. With the development of world construction technology and the enrichment of people's material life, the indoor living environment has changed greatly. The improvement of the airtight performance of houses makes indoor pollution accumulate. At the same time, poor ventilation increases indoor humidity, which is also conducive to the growth of molds and indoor dust mites, making dust mites the most common allergen in the living environment. The changes in lifestyle and working style have made people spend 80% of their time indoors. The environmental changes have promoted the breeding of dust mites, and the extension of people's stay indoors has also increased the contact with dust mite allergens, resulting in an increase in the incidence of diseases such as dust mite allergic asthma. Therefore, the prevention and control of dust mites have attracted extensive attention from researchers around the world. Most of the existing textile fabrics do not have the effect of repelling mites. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to provide a textile fabric with regenerated cellulose fibers, which can solve the problem that most of the existing textile fabrics do not have the effect of repelling mites.

[0004] Technical Solution: To solve the above technical problems, according to one aspect of the present invention, more specifically, a textile fabric with regenerated cellulose fibers includes the following components: regenerated cellulose fibers, polyester, fenamidone, deltamethrin, lauryl carboxymethyl sodium imidazoline acetate, coupling agent 1, polypropylene, yttrium oxide, zirconia, titanium dioxide, and coupling agent 2.

[0005] Furthermore, the textile fabric includes the following components by weight: 60 - 75 parts of regenerated cellulose fibers, 25 - 40 parts of polyester, 3 - 5 parts of fenamidone, 3 - 5 parts of deltamethrin, 3 - 5 parts of lauryl carboxymethyl sodium imidazoline acetate, 0.25 - 0.4 part of coupling agent 1, 30 - 60 parts of polypropylene, 0.04 - 0.16 part of yttrium oxide, 0.04 - 0.16 part of zirconia, 0.06 - 0.2 part of titanium dioxide, and 0.01 - 0.04 part of coupling agent 2.

[0006] Furthermore, the coupling agent 1 is one or more of isopropyl tris(dioctylpyrophosphate acyl) titanate and di(isopropyl) bis(triethanolamine) titanate.

[0007] Furthermore, the coupling agent 2 is one or more of isopropyltris(dioctylphosphate) titanate, 1,2-stearin glyceride, and γ-chloropropyltriethoxysilane.

[0008] Furthermore, the manufacturing steps of the fabric are as follows:

[0009] S1. Mix polyester with coupling agent 1 to obtain modified polyester;

[0010] S2. Mix the modified polyester with fenamidone, deltamethrin, and sodium lauroyl carboxymethyl imidazoline acetate, extrude and slice to obtain polyester chips;

[0011] S3. Heat and melt the polyester chips, extrude and spin them into mite-repellent fibers;

[0012] S4. Mix yttrium oxide, zirconia, and titanium dioxide, and crush them to obtain far-infrared powder;

[0013] S5. Mix coupling agent 2 with the far-infrared powder to obtain modified far-infrared powder;

[0014] S6. Blend the modified far-infrared powder with polypropylene, extrude and slice to obtain far-infrared polypropylene chips;

[0015] S7. Heat and melt the far-infrared polypropylene chips, extrude and spin them to obtain far-infrared polypropylene fibers;

[0016] S8. Weave the regenerated cellulose fibers, mite-repellent fibers, and far-infrared polypropylene fibers by machine to obtain a textile fabric with regenerated cellulose fibers.

[0017] Furthermore, in step S4, after mixing yttrium oxide, zirconia, and titanium dioxide, the average particle size of the far-infrared powder obtained by crushing is 0.3 - 0.7 μm.

[0018] Furthermore, in step S5, the mixing conditions of coupling agent 2 and the far-infrared powder are 600 r / min and stirring for 3 min.

[0019] Furthermore, in step S8, the method of weaving the regenerated cellulose fibers, mite-repellent fibers, and far-infrared polypropylene fibers by machine is to manually mix a small amount of the regenerated cellulose fibers, mite-repellent fibers, and far-infrared polypropylene fibers, make them into a roll by opening and cleaning cotton machinery, make them into a mixed sliver by carding machinery, and then pass the mixed sliver through a pre-drawing frame, drawing frame, roving frame, spinning frame, and winding frame in sequence to obtain a textile fabric with regenerated cellulose fibers.

[0020] Beneficial effects: Regenerated cellulose fiber is a fiber made from natural cellulose such as wood, cotton linter, bamboo, etc. through chemical dissolution and spinning processes. It is naturally degradable and more in line with the requirements of green environmental protection. Polyester is mixed with fenamidone, deltamethrin, and sodium lauroyl carboxymethyl imidazoline acetate, so that the polyester contains acarid-repellent components. During the process of wearing and washing textiles, the surface layer of acarid-repellent agent is washed off, and new acarid-repellent agent dissolves from the inside to supplement it, forming a new acarid-repellent layer on the fabric surface to play the role of acarid prevention, so that the textile fabric has a lasting acarid-preventing effect. Adding far-infrared powder yttrium oxide, zirconia, and titanium dioxide that can effectively release negative ions into polypropylene makes the textile fabric able to continuously and efficiently release negative ions, and can absorb a large amount of heat energy of the heat source and convert it into far-infrared rays of 5 - 15 microns to emit to the human body, generating a local warming effect on the human body, promoting blood circulation, and at the same time effectively inhibiting the dissipation of human body heat.
