The demand for textile products has been increasing year by year.

On the contrary, the amount of cultivated land on the earth is gradually shrinking, which makes the supply of main raw materials of cotton, cotton, more and more intense, and the gap may be bigger and bigger in the future.

According to people concerned, over the past 3 years, with wheat, corn, rice and other food crops

Price

With increasing growth, cotton planting area has been losing step by step. In 2 years, the planting area has been reduced by 14 million mu.

Therefore, develop textile materials that can replace cotton and make up for them.

cotton

Lack of this gap is particularly important, and it is also a problem that the textile industry must face.

From the point of saving resources and improving the utilization ratio of raw materials, the development of new technologies and materials for energy conservation and environmental protection is the general trend of the textile industry.

At present, a considerable number of new materials have been developed. The clothing times has collected some new materials and made a joint survey with the first textile network. The textile and apparel industry has made star rating on these new materials. Among them, bamboo fiber has been awarded the "star of creativity" and "the star of the future", and the new hemp plant fiber has been "star of environmental protection" and "low-cost star".

Six or seven years ago, the non cotton movement in foreign countries had begun. People gradually reduced their wear of cotton products and walked towards plants. Corn fiber (PLA fiber, PLA fiber) became a good substitute for cotton.

Many domestic enterprises have also developed new bio based fibers and fabrics derived from corn.

Corn fiber is a synthetic fiber made from corn and wheat starch, which is fermented into lactic acid and then polymerized.

This fiber is biodegradable, corn fiber is smooth and smooth, strong strength, moisture absorption and breathability, processed products have silky luster and comfortable skin touch and feel, good drapability, good heat resistance and anti ultraviolet function, good wearability.

Because the fiber completely does not use petroleum and other chemical raw materials, its waste can be decomposed into carbon dioxide and water under the action of microorganisms in soil and sea water, and it will not pollute the earth's environment.

Because the raw material of the fiber is starch, its regeneration cycle is short, about one to two years, and the carbon dioxide produced can be reduced by plant photosynthesis in the atmosphere.

The combustion of PLA fiber has almost no nitric oxide, and its combustion heat is about 1/3 of polyethylene and polypropylene.

With the development of seaweed fiber project, another source of textile fiber, seaweed fiber, has been opened up.

Xia Yanzhi, the leader of seaweed fiber research and development, and deputy director of the National Key Laboratory of fiber new materials and modern textile, Qiingdao University, said that alginate fiber has many new characteristics of many traditional fibers, and its flame-retardant properties exceed 10 percentage points of international standards, and there will be no clear fire in the air.

Seaweed fiber has certain radiation protection, antibacterial and moisturizing effect, and has broad application prospects in biomedicine, high-grade clothing, environmental protection and other fields.

Compared with traditional land fibers and synthetic fibers, alginate fiber can save land and clean the environment, and the production process is completely low carbon green.
