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 fabrics. The polyvinyl chloride fibers penetrate through the nano mesoporous titanium dioxide hollow spheres to disperse the stress born by the polyvinyl chloride fibers, so that the tensile property of the quilt cover fabric is improved; when ultraviolet rays irradiate the fabric, the transmitted ultraviolet rays are refracted and scattered in the hollow sphere, so that the fabric is effectively prevented from yellowing; chitosan reacts with glutaraldehyde, hydrophilic groups are connected to the surface of silicon dioxide through chemical bonds, and the hydrophilicity of the fabric is increased; the modified silicon dioxide powder is sprayed on the surface of the base cloth to fill the pits with the size, the wear resistance of the fabric is increased while the fabric is kept flat, the modified silicon dioxide powder is limited by the curing liquid and the modified quartz sand on the fiber, and the anti-yellowing performance of the fabric is more durable while the wear resistance of the fabric is increased. The anti-yellowing wear-resistant fabric for the quilt cover, which is prepared by the invention, has the effects of anti-yellowing, 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
The yellowing of the fabric, also called "yellowing", refers to the phenomenon that the surface of a white or light-colored material is yellowing under the environmental conditions of light, chemicals and the like. The yellowing of textiles during storage, transport, wear and the like directly leads to economic losses, so that in recent years, fabric manufacturers and purchasers begin to pay more and more attention to this index. In general, an antioxidant commonly used in fabric materials is 2, 6-di-tert-butyl-p-cresol, which reacts chemically with nitrogen oxides in the air to form 2, 6-di-tert-butyl-p-nitrophenol, which is colorless in an acidic state, sublimates very easily at room temperature to transfer, and immediately yellow when encountering alkaline substances.
Most of the yellowing treatment methods are to arrange substances capable of absorbing or reflecting ultraviolet rays on the surface of the fabric, but the substances capable of absorbing or reflecting ultraviolet rays abrade and fall off in the friction process of the fabric due to arrangement on the surface, so that the yellowing resistance 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 properties of the ultraviolet-absorbing substances are enhanced, the anti-yellowing performance of the fabric can be effectively kept for a long time, and finally, the protective layer is arranged on the surface of the fabric to protect the ultraviolet-absorbing substances from abrasion and increase the wear resistance of the fabric.
