Abstract
The invention discloses anti-yellowing wear-resistant fabric for a quilt cover and a preparation process thereof, and relates to the technical field of fabric. The polyvinyl chloride fiber penetrates through the nano mesoporous titanium dioxide hollow sphere to disperse the stress on the polyvinyl chloride fiber and increase the tensile property of the quilt cover fabric; when the ultraviolet rays irradiate on the fabric, the transmitted ultraviolet rays are refracted and scattered inside the hollow spheres, so that the fabric is effectively prevented from yellowing; the chitosan reacts with glutaraldehyde, and hydrophilic groups are connected to the surface of the silicon dioxide through chemical bonds, so that the hydrophilicity of the fabric is increased; the modified silicon dioxide powder is sprayed on the surface of the base fabric, so that pits in large and small sizes are filled, the wear resistance of the fabric is improved while the fabric is kept smooth, the modified silicon dioxide powder is limited by the solidified liquid and the modified quartz sand on the fiber on two sides, and the anti-yellowing performance of the fabric is more durable while the wear resistance of the fabric is improved. The anti-yellowing wear-resistant fabric for the quilt cover, prepared by the invention, has the effects of yellowing resistance, wear resistance and quick drying.
Description
Technical Field
The invention relates to the technical field of fabrics, in particular to an anti-yellowing wear-resistant fabric for a quilt cover and a preparation process thereof.
Background
Yellowing of the fabric, also called "yellowing", refers to the phenomenon that the surface of a white or light-colored material is yellowed under the environmental conditions of light, chemicals and the like. The yellowing of textiles during storage, transportation, wearing and the like directly causes economic loss, so fabric manufacturers and purchasers have paid more and more attention to the index in recent years. Generally, the antioxidant commonly used in the fabric material is 2, 6-di-tert-butyl-p-cresol, which reacts with nitrogen oxide in the air to produce 2, 6-di-tert-butyl-p-nitrophenol, which is colorless in an acidic state, is easy to sublime and transfer at room temperature, and is immediately yellowed when encountering an alkaline substance.
Most of the treatment methods for yellowing are substances capable of absorbing or reflecting ultraviolet rays on the surface of the fabric, but the substances capable of absorbing or reflecting ultraviolet rays are worn and fall off in the process of rubbing the fabric due to the surface finishing, so that the anti-yellowing performance of the fabric is not durable enough; according to the anti-yellowing fabric, the ultraviolet-absorbing substances are added into the spinning solution, the mechanical property of the ultraviolet-absorbing substances is enhanced, the anti-yellowing performance of the fabric can be effectively maintained for a long time, and finally, the upper protective layer is arranged on the surface of the fabric, so that the ultraviolet-absorbing substances are protected from being abraded, and the abrasion resistance of the fabric is improved.
