Nano sun-resisting finishing agent and its preparation method and finishing method for textile

Abstract

The invention relates to a sun-screening finishing agent and its preparing method as well as a fabric post-finishing method, and the nano sun-screening finishing agent is basically composed of nano titanium dioxide, adhesive, amino-functional silicone, moisture-absorbing and perspiring agent, and water. The preparing method: a. weighing the above matters in specified proportion; b. heating the adhesive, adding the TiO2 in the adhesive, and stirring at high speed; c. keeping temperature at 65 deg.C, and adding in amino-functional silicone, and moisture-absorbing and perspiring agent in turn to stir at high speed; d. keeping 65 deg.C, and adding in water for high-speed stirring. The post-finishing method: a. selecting textile fabrics; b. soaking in dip-rolling liquor; c. drying; d. baking to make the finished product. It has good clothing property and sun-screening effect and largely increase sunlight and dyeing fastness, the product has no toxicity and does not stimulate the skin, the handle is soft, good breathbility, and can used in clothing and sun shields.

Description

technical field [0001] The invention relates to a sunscreen finishing agent, a preparation method and a textile post-finishing method, and is particularly suitable for a nano-scale sunscreen finishing agent, a preparation method, a textile finishing method using the sunscreen finishing agent, and a method for improving light fastness and color fastness. Background technique [0002] With the rapid increase of Freon and other fluorine compounds and global carbon dioxide emissions, the ozone layer in the atmosphere is becoming thinner, and the intensity of ultraviolet rays reaching the ground is gradually increasing. The number of patients with various skin diseases caused by sunlight has increased significantly. People have changed from pursuing sunbathing in the past and taking dark skin color as the aesthetic trend to vigorously researching on ultraviolet radiation and sun protection. In March 1995, the world's first international symposium on UV protection was held in Lon...

Problems solved by technology

The existing technology uses anti-ultraviolet blocking materials, mainly including ceramic powder or organic compounds. These materials play a certain role in protecting ultraviolet rays, but they have poor wearability, hard hand feeling, airtight, not washable, and low protection level. , no effect after several washes, long production cycle and other disadvantages
