How many steps are there in the production process of acrylic yarn?

Acrylic yarn is a kind of synthetic fiber, which is usually used to make clothing, household goods, industrial goods, etc. It has excellent cationic dye affinity, antibacterial property and corrosion resistance. In the booming fashion industry, acrylic yarn is widely used and has become an important part of the textile industry. This paper will discuss the production, advantages and application of acrylic yarn.

1、 Production of acrylic yarn

Acrylic fiber yarn is mainly composed of polypropylene fiber and polybutyronitrile fiber, which is produced through multiple processes such as spinning and dyeing. The production process mainly includes the following steps:

1. Pretreatment: pretreat the raw materials of polybutyronitrile and polypropylene to remove impurities, additives, etc., and make them reach a pure state.

2. Spinning: The raw materials are heated and melted by the spinning machine, and then the fibers are formed on the high-speed rotating inner metal cylinder.

3. Forming: cooling the fibers produced by the spinning machine with water to form silk thread. After several processes such as twisting and finishing, various specifications of acrylic yarn can be produced.

4. Dyeing: Dye the formed yarn to make it bright in color, soft in texture and more excellent in color fastness and washability.

Advantages of acrylic yarn

Excellent dyeing performance: acrylic yarn fiber has excellent cationic dye affinity, which can make the dyeing agent better penetrate into the fiber and make the dyeing more uniform and bright.

Antibacterial property: Acrylic yarn has certain antibacterial property, which is not easy to breed bacteria and mold, and can effectively ensure the health and environmental protection problems of clothing and household products.

Corrosion resistance: In some extreme environments, such as acid, alkali, oxidant and other strong corrosive environments, acrylic yarn has more excellent corrosion resistance.

High tensile strength: acrylic yarn fiber has high tensile strength, higher tensile strength and twist, and is not easy to deform and break during wearing and using.
