As modern humans pay more and more attention to the protection of ultraviolet rays and the development of new additives, textiles with this function have very broad prospects.

Currently, UV-resistant textiles include shirts, sportswear, work clothes, uniforms, curtains and parasols, etc., and their UV blocking rate can reach more than 95%. This kind of textile also has certain limitations, that is, the anti-UV additives are easy to volatilize after being introduced into the fiber, and it is difficult to maintain the sun protection and cooling function for a long time.

Low carbon concept

The background and definition of the formation of low-carbon economy

The so-called low-carbon economy refers to reducing the consumption of high-carbon energy such as coal and oil and reducing greenhouse gas emissions as much as possible through technological innovation, institutional innovation, industrial transformation, new energy development and other means under the guidance of the concept of sustainable development. An economic development form that achieves a win-win situation between economic and social development and ecological and environmental protection (that is, an economic model based on low energy consumption, low pollution, and low emissions).

In recent years, with the continuous growth of the global population and economic scale, environmental problems and their causes caused by energy use have been increasingly recognized, not only the harm of smog, photochemical smog and acid rain, but also the concentration of carbon dioxide (CO2) in the atmosphere. Global climate change caused by rising temperatures has also been confirmed as an indisputable fact. In this context, low-carbon economy emerged as the times require. As a cutting-edge economic concept with broad social nature, low-carbon economy has also involved the textile and clothing field.

Ways to realize low-carbon textiles

With the arrival of the low-carbon wave, the development speed, proportion of new product development, and new product production speed of low-carbon and environmentally friendly clothing in developed countries are increasing day by day. Its implementation methods have developed to:

According to a survey, 80% of consumers across the country like to buy clothing made of natural fiber fabrics, of which pure cotton accounts for 47.87%, a large proportion. therefore. The development of natural fiber fabrics is an important step in the production of low-carbon and environmentally friendly clothing. In addition to the more common varieties of cotton, linen, silk and wool, some rarer but distinctive varieties have also been developed, utilized and mined.

Use fibers with no or less pollution in the production process. Organic natural fibers (that is, crops that are not exposed to any chemicals during the growth process, and the fields where such crops are grown have not used chemicals for at least 3 years before planting). It is favored by sophisticated consumers for its good moisture absorption, breathability and biocompatibility. As thin summer clothing, linen fabrics are perspiration-resistant, light, breathable and comfortable; silk fabrics are soft, warm, breathable and comfortable and are often used as spring and summer fabrics, and have health care functions when worn close to the body; wool is elastic, has good hygroscopicity, and the fabric is plump and Warmth; cotton fiber is thin and soft, low-priced, suitable for inner and outer clothing in all seasons. Such as colored cotton fiber, colored wool fiber, chitin fiber, apocynum fiber, wood pulp fiber, etc.

Waterless dyeing technology, such as polyester supercritical carbon dioxide waterless dyeing technology. Dyeing with natural mineral pigments and natural plant dyes. For example, cellulase hydrolysis is used to remove hairiness and microfibers on cotton and its blended fabrics to replace the singeing process, saving energy and eliminating dust and waste gas pollution. The use of amylase desizing eliminates the chemical pollution caused by acid, alkali and oxidant desizing. Use pectinase, lipase, protease and other enzyme treatments to replace the traditional refining of cotton and its blended fabrics to reduce pollution sources.

In the dyeing and finishing process, biological enzymes are used to achieve a less pollution and pollution-free process. Use pigment enzymes to replace traditional sodium hypochlorite or hydrogen peroxide chemical bleaches. Try to discard dyes that can cause cancer and allergies, and choose dyes that can be enzymatically hydrolyzed for dyeing and printing, so that the residual dyes in the sewage can be easily decolored by enzymatic hydrolysis.

Using light refraction to form a variety of colored fibers, such as the multi-layer composite fiber developed by Tokyo Institute of Technology in Japan. The spacing between the composite layers is about 0.8 nanometers. After the white light is refracted by the fiber, it will emit the fresh color of Amazon butterflies without dyeing, which is very elegant.

Produce biodegradable fibers, such as Tencel fiber, soy protein fiber and various degradable synthetic fibers. Waste disposal must comply with environmental standards.
