At present, the shortage of global petroleum resources has become a serious problem that restricts the development of chemical fiber industry. In order to meet the market demand, there must be corresponding alternative resources to meet the needs of production development and consumption growth.

Therefore, the economy of renewable and degradable new materials that can replace oil is increasingly apparent. At the same time, the demand for energy conservation and emission reduction and environmental protection has also prompted the chemical fiber industry to pay more attention to environmental protection and reduce energy consumption.

The development of green biomass fiber and materials based on biomass engineering technology has become the new trend of leading the development of chemical fiber industry.

Bamboo fiber

It is a representative variety of biomass regenerated fiber in China, which has been gradually accepted by consumers, and the application field is expanding.

Seize opportunity, biomass regeneration fiber develops at full speed

With the improvement of people's living standard, consumers' demands for textiles are not only simple and warm, but also environmentally friendly and functional textiles and garments are gradually favored by consumers.

Cellulose, represented by cellulose, has won unprecedented opportunities for development because of its excellent properties such as moisture absorption, breathability, comfort and abundant resources.

At present, many kinds of fibers have been developed by using renewable resources at home and abroad. Among them, the most mature technology and the largest dosage are regenerated cellulose fibers, including viscose fiber, high wet modulus viscose fiber, Lyocell fiber, acetate fiber, copper ammonia fiber and so on.

Viscose

Fiber is the main variety of regenerated cellulose fiber. In 2009, China's capacity has reached 1 million 907 thousand and 200 tons, and its technology level and engineering level are at the advanced level in the world.

As viscose fiber production process is long, "three wastes" pollution, old equipment and higher production costs, western developed countries and South Korea and Japan have gradually stopped the production of viscose fiber.

At present, the growth of viscose fiber production capacity in the world is mainly concentrated in China.

In our country, when it comes to biomass fiber, bamboo fibers and hemp fibers are indispensable.

Regenerated cellulose produced from bamboo pulp and hemp pulp is a kind of regenerated cellulose fiber developed in China in recent years.

At present, Jilin chemical fiber Limited by Share Ltd, Hebei jishajiao Chemical Fiber Co., Ltd., Shandong Hailong Limited by Share Ltd, the PLA General Logistics Department Quartermaster Equipment Research Institute and many other enterprises are studying and developing these products.

The appearance of high wet modulus viscose fiber overcomes the common viscose.

fibre

Low wet strength and wet modulus and poor dimensional stability of fabrics.

At present, China Dandong chemical fiber group has officially realized the localization of high wet modulus fiber and launched lissai fiber.

Shandong Hailong Limited by Share Ltd's newly developed fiber is also an advanced high wet modulus fiber.

The double pressure of environment and cost has seriously hindered the development of viscose fiber. However, the Environmental Friendly Non viscose cellulose fibers such as Lyocell fiber and Novel fiber have attracted the attention of experts at home and abroad.

At present, the annual output of Lyocell fiber in the world is more than 120 thousand tons, of which Lenzing is the most important manufacturer.

Due to strong demand, Lenzing has announced that it will expand its capacity of 25% in Austria plant. At present, the total capacity of its Lyocell fiber has reached 130 thousand tons / year.

South Korea, Japan and Russia also have test lines for small batch production of Lyocell fibers.

Many units in China have carried out research and development of Lyocell fiber.
