Problems solved by technology

[0005] Sodium borate is added in the process of preparing the composite fiber in the present invention, and the sodium borate has a certain bonding performance. After being fixed by crosslinking, the titanium / silica sol is firmly combined on the surface of the acetate fiber, preventing the peeling of the sol layer on the fiber surface during the washing process. Reduce its stain resistance and solve the problem of lower stain resistance of existing fabrics under long-term washing

Abstract

The invention discloses a preparation method of a stain-resistant nanometer garment fabric. The specific preparation process comprises the following steps: adding complex blended cellulose acetate fibers and modified polyurethane fibers to acetone, wherein the complex blended cellulose acetate fibers and the modified polyurethane fibers are dissolved in acetone, carrying out heating to 80 DEG C, carrying out stirring for dissolving, adding sodium borate, adding hydrochloric acid, adjusting the pH of the solution to be 2, carrying out constant-temperature reflux reaction for 6-7 h, carrying outheating to 90 DEG C, adding trifluoroacetic anhydride, carrying out constant-temperature stirring reaction for 5h, carrying out evaporation to obtain solid substance, and carrying out washing and drying, thus obtaining complex solid fibers; and adding the complex solid fibers to a melt spinning machine for spinning, spinning the fiber filaments to form complex yarns, and weaving the complex yarns, thus obtaining the stain-resistant fabric. In the preparation process of the complex fibers, sodium borate is added, sodium borate has certain bonding property, after crosslinking and fixing, titanium / silica sol is firmly boned to the surfaces of the cellulose acetate fibers, and thus the phenomenon that during the washing process, the sol layers on the surfaces of the fibers is stripped, consequently, the stain-resisting property is reduced is avoided.

Description

technical field [0001] The invention belongs to the field of clothing fabrics, and relates to a stain-resistant nano clothing fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, there are higher requirements for the quality of clothes. For those who work in dirty oil-stained factories or auto repair companies for a long time, the stain resistance and tensile wear resistance of clothes have certain The existing stain-resistant fabrics usually bond nano-titanium dioxide in the fabric, and realize the stain-resistant performance of the fabric through the action of nano-titanium dioxide. At the same time, the high stain resistance of the fabric cannot be achieved only through the effect of titanium dioxide, and the stain resistance cannot be fully realized for the oil stains penetrating in the gaps of the fabric. The content of nano-titanium dioxide is reduced, which in turn reduces its oil resistance. Cont...
