Learn about filament weaving

As the closing work of the PyeongChang Winter Olympics, "Beijing 8 Minutes" made a stunning appearance, and 24 roller skaters wore white jumpsuits and roller skates to daze the scene. Their costumes are full of technology and futuristic, which makes people bright. These performance costumes are light, warm, windproof, breathable, stylish and beautiful, and their fabrics are produced by filament weaving.

At present, chemical fiber filament textiles with its unique feel, as well as anti-wrinkle, crisp, anti-pilling and other characteristics, are widely used in fashion women's clothing, outdoor sportswear, special protective clothing and other clothing fields.

Filament weaving and its development status

The chemical fiber filament weaving industry is an emerging industry that started in the 1980s, initially based on imitation silk, with the progress of science and technology, the industry has been rapid development, chemical fiber filament weaving has expanded to imitation cotton, imitation wool, imitation linen, imitation suede and other artificial fabrics, and the application has gradually expanded from clothing textiles to household textiles and industrial textiles. Output rose from 4.1 billion meters in 2000 to 48.2 billion meters in 2017, with an average annual growth rate of more than 15%, making it one of the fastest growing textile industries. With an annual output value of nearly 200 billion yuan and an annual export volume of more than 14 billion meters, it is the largest export of woven fabrics in the textile industry.

In 2017, China's chemical fiber production reached 49.196 million tons, accounting for more than 70% of all fiber production, of which more than 30 million tons of chemical fiber filament, more than 60% of chemical fiber filament used for weaving, chemical fiber filament in the replacement of silk, cotton, wool, hemp and other natural fibers, to meet the needs of people's lives played an important role. According to customs statistics, in 2017, China's total export of chemical fiber filament fabrics was 12.405 billion US dollars, an increase of 5.77%; The actual export volume reached 14.122 billion meters, an increase of 10.02%. Among them, the export of polyester filament fabric 12.186 billion meters, an increase of 9.55%; The export of nylon filament fabric was 435 million meters, an increase of 13.87%.

According to the National Bureau of Statistics, in 2017, the main business income of China's chemical fiber weaving and printing and dyeing processing industry was 132.809 billion yuan, an increase of 9.28%, a growth rate of 4.2 percentage points; The total profit was 6.577 billion yuan, up 22.37 percent year-on-year.

In 2017, the actual investment in China's chemical fiber weaving and printing and dyeing processing industry was 48.155 billion yuan, down 0.42% year-on-year. The investment of chemical fiber weaving enterprises is mainly used for equipment renewal and transformation of product development and upgrading, new enterprises and capacity expansion in industrial transfer, and some investment is used for sewage treatment and water reuse system transformation in accordance with the requirements of national and local energy conservation and emission reduction policies.

At present, more than 90% of China's chemical fiber filament weaving industry is concentrated in Wujiang District of Jiangsu Province, Jiaxing City and Changxing County of Zhejiang Province and Jinjiang City of Fujian Province and other coastal developed areas, and the industrial agglomeration is extremely high.

Characteristics of filament weaving industry

1. Short production process, low cost, high efficiency, low energy consumption

The chemical fiber filament weaving industry has obvious advantages in raw materials, labor and electricity costs, and is an emerging textile industry and a strong competitive industry. In addition, the chemical fiber filament has high strength, less broken ends, eliminating spinning and other links before weaving, and has many advantages of energy saving, labor saving and high production efficiency. Among all shuttleless looms, the gap between the technical performance of domestic equipment and the international advanced level is the smallest, and the price of a single unit is the lowest, so the chemical fiber filament weaving project based on the use of water jet loom has the least investment and the lightest investment pressure compared with other textile projects.

2. More product development and obvious innovation advantages

Because the raw materials of chemical fiber fabrics are manufactured by chemical and physical methods, changing these methods can produce chemical fiber raw materials with different properties, different shapes and different specifications. These different raw materials through the weaving process of pure weaving, interweaving, mixed different combinations and changes in organizational structure, coupled with printing and dyeing processing of different processes, can produce thousands of different functions, different characteristics, different styles of filament fabrics, innovation gives chemical fiber filament fabric products inexhaustible vitality.
