Abstract

The invention relates to ultraviolet screening agent, ultraviolet resistant fabric finishing liquid, and the finished fabric. The screening agent making method includes the following steps: preparing A solution that aqueous solution contains 0.3-0.5% acid which can be one of hydrochloric acid, sulfuric acid, nitric acid, glacial acetic acid, or phosphoric acid; preparing titanium source alcoholic solution as 100-0.5:1 volume ratio, stirring to form B solution; the titanium source can be one of titanic acid ethyl ester, titanic acid propyl ester, titanic acid butyl ester, or titanium tetrachloride; the alcohol can be one of ethanol, isopropyl alcohol, or butanediol; adding the B solution into the A solution as 5-9:1 volume ratio by stirring from room temperature to 100 degree centigrade; reacting for 24h; aging for 2-6h. The fabric finishing liquid contains 5-80% ultraviolet screening agent and water. The ultraviolet resistant fabric finishing adopts the produced finishing liquid to finish. The function is obvious. And the wash fastness is good.

Description

technical field [0001] The invention relates to textile post-finishing technology, including functional agent, fabric finishing solution and finished fabric, specifically a kind of ultraviolet shielding agent, anti-ultraviolet fabric finishing solution and the fabric finished by the fabric finishing solution, and the international patent classification number is intended to be Int. CL D06M13 / 50 (006.01). Background technique [0002] In recent years, with the continuous destruction of the atmospheric ozone layer, the amount of ultraviolet radiation on the ground has increased rapidly. Some experts believe that many diseases, including skin diseases and skin cancer, are related to excessive ultraviolet radiation. Therefore, it is urgent to carry out anti-ultraviolet finishing of textiles. The so-called ultraviolet light refers to the continuous spectrum with a wavelength range of 400-100nm, among which the spectrum of 400-320nm is called ultraviolet A (UVA); the spectrum of ...
