Characteristics and development of high water-resistant and breathable fabric-acetate fabric The main component of acetate fabric is acetate fiber. Acetate fiber is made of cellulose (that is, a natural substance extracted from wood pulp cellulose, which is the same chemical molecular component as cotton fiber) and acetic anhydride, etc., through a series of chemical finishing. The acetate filament fiber that can be used for spinning and weaving. It uses cellulose as the basic skeleton and has the basic characteristics of cellulose fiber; but its performance is different from that of regenerated cellulose fiber (viscose? Cupra). Certain properties of synthetic fibers.
The wonderful characteristics of acetate fiber:
1. Good thermoplasticity: The acetate fiber softens at 200°C ~ 230°C and melts at 260°C. This feature makes the acetate fiber thermoplastic and similar to synthetic fibers. After plastic deformation, the shape does not recover and has permanent deformation.
2. Excellent coloring performance: Acetate fiber can usually be colored with disperse dyes, and has good coloring performance, bright colors, and its coloring performance is better than other cellulose fibers.
3. Appearance resembles mulberry silk: The appearance of acetate fiber? Wanze is similar to mulberry silk, and it has a soft and smooth feel and similar to mulberry silk. Its specific gravity is the same as that of mulberry silk. The woven fabric made of acetate silk is easy to wash and dry, and is not mildew and worm-eaten. The elasticity is better than that of viscose fiber.
4. Performance close to mulberry silk: Compared with the physical and mechanical properties of viscose fiber and mulberry silk, acetate fiber has lower strength and greater elongation at break. Although the ratio of wet strength to dry strength is lower, it is higher than that of viscose fiber. , The initial modulus is small, the moisture regain is lower than that of viscose fiber and mulberry silk, but higher than that of synthetic fiber. The ratio of wet strength to dry strength? Relative hook strength and knot strength? Elastic recovery rate is not different from that of mulberry silk. Big. Therefore, the performance of acetate fiber is closest to that of mulberry silk among chemical fibers.
Acetate fabrics have many properties that surpass those of cotton and linen fabrics, such as moisture absorption and breathability, non-sweat, easy to wash and dry, no mildew, no moth, comfort on the skin, and absolute environmental protection.
Acetic acid cloth is not charged; it is not easy to absorb dust in the air; dry cleaning, water washing and machine hand washing below 40℃ can overcome the multi-bearing bacteria of silk and wool fabrics; the weakness of dust and only dry cleaning, and no wool woven fabrics The shortcomings of insects are easy to take care of and store, and the acetate fabric has the resilience and smooth feel of woolen fabric.
Acetate fabric development: Acetate fiber has good coloring performance, bright color, bright appearance, soft and comfortable nature, but low strength. The development of acetate fabric needs to "strengthen the strengths and avoid weaknesses". Acetate filaments are widely used in clothing, furnishings and decorative fabrics. Acetate filaments can be used in the lining of work clothes, shirt skirts, casual clothes, bridal gowns, children's clothes and T-shirts. Woven or knitted fabrics for work wear, shirt skirts, casual wear, bridal gowns and children's clothing, T-shirts can be made of 100% acetate filament, or can be blended with acetate filament and chemical fiber fabrics such as rayon , Elastic fiber, nylon, cotton, or linen, wool, silk polyester, etc. Velvet fabric, decorative silk, high-grade lining silk, embossed silk, fashion fabric, high-grade knitted fabric, T-shirt fabric, etc. Woven furnishing fabrics generally use acetate filaments as the warp and cotton yarn or rayon as the weft. The decorative fabrics are mostly satin, and satin can also be used for ribbons, artificial flowers and ties.
