Acrylic fiber is

Polyacrylonitrile fiber

In our country's commodity name, the basic raw material is acrylonitrile.

It is obtained by copolymerization of acrylonitrile with second monomers (methyl acrylate or methyl methacrylate, etc.), third monomer (sodium acrylate sulfonate, etc.), and then by wire drawing.

Its properties are very similar to wool, so it is called "synthetic wool".

Acrylic fiber is

Synthetic fiber

One of the three varieties, its output ranks third in polyester and nylon.

Especially in recent years, in order to meet the needs of special purposes, many new denatured fibers have been made by chemical and physical modification, which has expanded the use of acrylic fiber in civilian and industrial applications, so acrylic fiber is a promising fiber.

Classification and specifications

1, acrylic staple fiber: 1.4D * 38mm, 1.5D * 38mm, 5D x 89/140mm, 8D * 89/140mm, 10D * 127mm, etc.

2, acrylic regular bar: 3D x 70-127mm, 3D x 102mm, 3D x 76-127mm, 3D * 76-102mm, etc.

3, acrylic blending bar: 3D x 95mm, 3D x 76mm, 3D x 102mm, 3D * 152mm, 3D * 76-127mm;

4. Acrylic bulky strips: 3D * 152mm, 3D * 85mm, 3D * 97.5mm, etc.

5, from the perspective of gloss is divided into: no light, half light, bright three.

Properties and uses

Acrylic fibres

It has many excellent properties, short fiber bulky, soft, curly, appearance and feel are very like wool.

The unique characteristic of acrylic fiber is thermoelasticity (heat shrinkage), which can be used to process bulky yarn.

Acrylic fiber is one of the best textile fibers for its light fastness and weather resistance.

Acrylic acid is good in acid resistance, stable in oxidizing agent and organic solvent, and poor in alkali resistance. It is easy to turn yellow when treated with dilute alkali or ammonia.

Acrylic fiber has a wide range of uses, short fibers can be pure spinning, and can also be blended with wool and other fibers to make high-grade wool.

Acrylic fibers can be processed into blankets, carpets or artificial fur, and can also be made into bulky yarns for knitting materials.

Because of its good light fastness, it can be used for curtain, curtain and gun clothing.

Denatured polyacrylonitrile fiber has good fire resistance and is not easy to catch fire. It can extinguish itself after fire.

Imported acrylic fiber is a statutory inspection product. Imported acrylic fiber is not inspected by the China Inspection and quarantine department, and is not allowed to be sold and used.

The main inspection basis for import acrylic fiber is trade contract, based on the quality index and amplitude stipulated in the contract.

According to SN/T0061 - 92, "inspection rules for short fibers of denatured acrylic (nitrile, polyacrylonitrile))"; SN/T0060 92 "inspection regulations for imported polyester, acrylic and nylon staple"; SN/T0017 - 96 "determination method of fiber length for import and export chemical fiber, wool fiber"; SN/T0055 92 "inspection specification for imported acrylic tow"; SN/T0461-95 "inspection rules for imported chemical fiber regular bars"; SN/T0472-95 "testing method for defect content of imported acrylic fiber".
