Acrylic fiber and its uses

Acrylonitrile fiber and its uses

fine denier

Both can imitate artificial suede, and microfiber is softer. The fabric can be used as outerwear, leather shoe fabrics, etc.

Colored silk

The fiber has uniform coloring, good color fastness, high product quality, low post-processing costs, and less three-waste pollution. It can be processed into various clothing products and products with good light resistance by pure spinning, mixed fiber and yarn-dyed weaving.

Modified silk (mainly refers to modified polyester dyeable with cationic dyes)

It can be dyed with cationic dyes or disperse dyes at normal temperature and pressure. The product has bright color, rich tones, high color fastness, low cost, and easy-to-use piece dyeing method to achieve the effects of cross-dying, white space, and dark and light colors. It is fast and economical to change the color of the design and change the variety. With the development of new varieties, the varieties of fabrics will be continuously updated. In addition to being used in clothing, polyester filament has greater potential in decorative and industrial yarns, such as tire cords, ropes, fishing nets, conveyor belts, high-pressure oil pipelines, etc.

It is made of 1 to 2 pieces of ordinary cotton yarn, wool yarn or nylon and spandex combined and twisted. It is often used to weave elastic labor cloth.

Characteristics and applications of Lyocell fiber

Part.8

Lyocell is a new, environmentally friendly fiber that is hailed as the “green fiber of the 21st century” by the international textile industry. Its excellent properties of natural fibers and synthetic fibers allow the product to combine the moisture absorption and breathability of cotton, the feel and luster of silk, the strength of chemical fibers, and the comfort of wool. Its great affinity with natural fibers enables the development of a variety of products. High value-added woven and knitted products have extremely broad market prospects.

Characteristics of Lyocell (Tencel short fiber, Newcell filament yarn) fiber and yarn:

1. It has excellent characteristics of cellulose fiber. Lyocell fiber fabric has a refreshing feel, good moisture absorption and breathability, and has the drape of silk. The touch can change from cotton to wool, silk, and various other feelings.

2. High strength. The dry strength of Lyocell fiber is close to that of polyester fiber, while the wet strength only decreases by 15%, which is far superior to viscose fiber.

3. Fibrillation. When Lyocell fiber is in a wet state, small fibrils are pulled out of the fiber surface under mechanical force, which can change the properties of the fabric surface. Through enzyme treatment, longer fibrils are removed and secondary fibrillation is performed to obtain a peach skin effect.

4. Good dimensional stability. Lyocell fiber fabric has low shrinkage and good washability.

Lenzing Lyocell has developed the following product lines:

Lenzing Lyocell MICRO (Lenzing Lyocell microfiber), Lenzing Lyocell LF (Lenzing Lyocell

Ser LF fiber), Lenzing Lyocell FILL (Lenzing Lyocell FILL fiber), etc.

The main purpose:

The development of Lyocell products roughly includes six product series: denim, suits, casual wear, yarn-dyed fabrics, shirts and underwear, and knitting.

Acrylic fiber and its uses

Part.9

Acrylic fiber – a modified acrylic fiber, which is a copolymer of acrylonitrile monomer and vinyl compounds containing flame retardant elements. It has a wool-like feel and high flame retardancy, and is acid and chemical resistant. . As a functional fiber, this fiber has been widely used in Japan, Europe and the United States for home textiles, protective clothing fabrics, decorative textile materials, etc.

Fiber type: cotton type, wool type, high shrinkage type

Fineness: 1.5DTEX-20DTEX

Length: 28-120mm

Oxygen limiting index: ordinary type 28-30

High flame retardancy: 30-34

Gloss: glossy, semi-matt, matt

Acrylic chlorine fiber product features:

Excellent flame retardant properties. ——The natural flame retardant properties of the fiber enable the material to pass the stringent flame retardant requirements of various countries. Even if it is blended with other natural fibers, it still has unchanged flame retardant properties. ​

Natural, soft feel. ——Acrylonitrile fiber has softness, natural feel, water absorption performance and comfort similar to other natural fibers.

There is no melting or shrinkage during combustion. ——There is no shrinkage or melting phenomenon when nitrile chlorine fiber clothing fabric is burned, but only carbonization, which effectively prevents skin burns caused by melt droplets.

The material has good chemical stability – resistant to acids, alkalis and other general organic and inorganic drugs, so it is used as filter cloth materials, special protective clothing materials and other industrial materials.

The material has good dyeing properties – bright color, good color fastness, sun resistance, no obvious degradation by sunlight, and can be used for parasols, etc.

Mainly used for: interior decoration, curtains, seat covers, and aviation blankets of various cars, trains, ships, airplanes, hotels, and conference rooms.

Polychloropropylene fiber and polychloropropylene fiber

Part.10

Polyvinyl chloride fiber is the product name I used for polyvinyl chloride fiber. The international product names are Rowell, Peceu (PCU), etc. It is one of the main varieties of chlorine-containing fiber.

The raw materials for manufacturing chlorine fiber are easy to obtain and the cost is low. Wet or dry spinning methods can be used.

Fiber specific gravity: about 1.4g/cm3

Fiber strength: approximately 2.64cN/dtex

Elongation at break: 12~28%

It has good elasticity, good flame resistance, wear resistance and weather resistance, and its aggregate has good warmth retention properties.

Main defects: Very sensitive to heat. In boiling water, the fiber can shrink significantly, the strength decreases, and the elongation increases to 150~280%, so the fabric cannot withstand ironing, has poor hygroscopicity, is difficult to dye, and is easy to produce static electricity.

Main uses: flame-proof sofa cloths, mattress cloths and other interior decoration products, chemical-resistant overalls, filter cloths, or processed into knitwear and warm cotton fillings, etc. In addition, the chlorine fiber can be used to produce a large amount of anions through friction, which has a certain therapeutic effect on the human body, and can be made into health care products.

The United States calls PVC fiber “Salon”, which mainly contains vinylidene chloride (more than 80%). PVC fiber has stable chemical properties and is difficult to dye. Its specific gravity is the heaviest among current textile fibers, at 1.7g/ cm3, the moisture regain is 0%, and the moisture absorption capacity is poor; the fiber breaking strength is 2.12cN/dtex, and the elongation is 15~25%; PVC has good flame retardancy and does not support combustion. Polypropylene fiber comes in two types: filament fiber and short fiber.
