Present Situation And Prospect Of Anti Ultraviolet Textiles

At present, UV resistant textiles include shirts, sportswear, work clothes, uniforms, curtains and sunshade umbrellas. The UV shielding rate can reach over 95%.

This textile also has certain limitations, that is, UV resistant additives are easy to volatilize after being introduced into the fiber, so it is difficult to keep the function of sunscreen and cooling for a long time.

So-called

Under the guidance of the concept of sustainable development, through technological innovation, system innovation, industrial pformation, new energy development and other means, as far as possible to reduce coal and oil and other high carbon energy consumption, reduce greenhouse gas emissions, to achieve economic and social development and ecological environment protection of a win-win economic development form (that is, low energy consumption, low pollution, low emissions based on the economic mode).

In recent years, with the continuous growth of the global population and economy, the environmental problems caused by energy use and its inducements have been continuously recognized. It is not only the hazards of smoke, photochemical smog and acid rain, but also the global climate change brought by the increase of atmospheric carbon dioxide (CO2) has been recognized as an indisputable fact.

Against this background, low carbon economy came into being.

As a leading economic concept with a wide range of sociality, low carbon economy has also been involved in the field of textile and clothing.

With the advent of the low carbon tide, the development speed, the proportion of new product development and the production speed of new products in developed countries are increasing.

According to a survey, 80% of consumers in the country like to buy.

Fabric clothing, of which 47.87% of pure cotton accounted for the largest proportion.

Therefore, the development of natural fiber fabrics is an important step in the production of low carbon environmentally friendly clothing.

In addition to the more common varieties of cotton, linen, silk and wool, some rare but distinctive varieties are also developed and used for picking up.

No pollution or less pollution in the production process. Organic natural fibers (that is, crops that do not touch any chemicals during growth, and fields that are grown for at least 3 years before planting).

With its good moisture absorption, breathability, biological capacity of deep fertilization fees favored.

Linen fabrics are thin summer clothing, sweating, light and ventilating and comfortable. Silk fabrics are soft, warm and moisture comfortable, and are used as spring and summer fabrics. They have health care functions for body wear, wool is elastic, moisture absorption is good, fabric is full and warm, cotton fiber is thin and soft, and its price is low, which is suitable for all seasons.

Such as colored cotton fibers, colored wool fibers,

Apocynum fiber, wood pulp fiber and so on.

No water dyeing technology, such as polyester supercritical carbon dioxide, water free dyeing technology.

Dyeing with natural mineral pigment and natural plant dyestuff.

If cellulase hydrolysis is used to remove hairiness and microfiber on cotton and its blended fabric instead of singeing process, it saves energy, and has no dust and exhaust pollution. Amylase desizing is used to avoid chemical pollution caused by acid, alkali and oxidant desizing.

Pectinase, lipase, protease and other enzymes were used to replace the traditional cotton and its blended fabrics to reduce the pollution source.

In dyeing and finishing, biological enzyme is used to achieve less pollution and no pollution.

Bleaching enzymes are used instead of traditional sodium hypochlorite or hydrogen peroxide chemical bleaching agents. As far as possible, carcinogenic and allergenic dyes are discarded, and dyestuffs can be dyed and printed by enzymatic hydrolysis so as to make the residual dyes in the waste water easily enzymolytic and decolorizing.

A variety of colored fibers are refracted by light rays, such as multilayer composite fibers developed by Tokyo Institutet of Technology, Japan. The composite layer spacing is about 0.8 nm. After the white light is refracted, the color of the fresh Amazon butterfly will be released without dyeing.

The production of biodegradable fibers, such as Tencel fiber, soybean protein fiber and a variety of degradable synthetic fiber.

Waste disposal must conform to environmental standards.
