Problems solved by technology

Due to the small molecular weight of organic UV absorbers and their poor compatibility with high-molecular acrylate coating adhesives, the organic matter on the surface of the fabric after coating will seep out and volatilize, which will affect the appearance of the fabric and the anti-ultraviolet effect is also unstable.
It has seriously affected the application of anti-ultraviolet fabrics on umbrella surfaces

Abstract

The invention discloses an ultraviolet-proof finishing method of a fabric for umbrellas. A gray fabric of the fabric for the umbrellas is made of a 190T cationic fabric; the ultraviolet-proof finishing method is characterized by comprising the following steps: (1) desizing; (2) adding dyes in a dye vat; (3) adding aqueous dispersion of nanoscale water-based ultraviolet shield agents in the dye vat, wherein the aqueous dispersion of nanoscale water-based ultraviolet shield agents comprises the following materials by weight parts: 30 parts of ionized water, 0.3 part of a dispersing agent, and 3-3.5 parts of TiO2 nanoparticles; (4) dyeing and preserving heat for 30min; (5) shaping; (6) carrying out waterproof treatment; and (7) coating a surface layer. According to the method, a nano material can be successfully applied to the fabric with an ultraviolet-proof function for the umbrellas, and the finished fabric for the umbrellas has the ultraviolet screening rate reaching more than 95%, has the ultraviolet-proof function of the nano material enduringly, and can ensure the original style of a textile fabric.

Description

technical field [0001] The invention relates to a treatment method for fabrics, in particular to a treatment method for umbrella fabrics, in particular to a UV-resistant finishing method for umbrella fabrics. Background technique [0002] At present, the conventional anti-ultraviolet finishing of umbrella fabrics mostly adopts the coating method, that is, organic ultraviolet absorbers (such as benzophenones, benzotriazoles, etc.) are added to the coating adhesive to achieve the anti-ultraviolet effect of the fabric Effect. Due to the small molecular weight of organic UV absorbers and their poor compatibility with high-molecular acrylate coating adhesives, the organic matter on the surface of the fabric after coating will seep out and volatilize, which will affect the appearance of the fabric and the anti-ultraviolet effect is also unstable. . Have had a strong impact on the application of anti-ultraviolet fabric on umbrella surface. Contents of the invention [0003] Th...
