Characteristics and development of highly waterproof and breathable fabric-acetate fabric

The main component of acetate fabric is acetate fiber. Acetate fiber is made from cellulose (a natural substance extracted from wood pulp cellulose, which has the same chemical molecule as cotton fiber) and acetate anhydride as raw materials, and is made through a series of chemical processes. 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 properties are different from regenerated cellulose fiber (viscose? cupro). Some properties of synthetic fibers.

The magical characteristics of acetate fiber:

　1． Good thermoplasticity: acetate fiber softens at 200°C ~ 230°C and melts at 260°C. This feature makes acetate fiber thermoplastic similar to synthetic fibers. It does not recover its shape after plastic deformation and has permanent deformation.

　2. Excellent dyeability: Acetate fiber can usually be dyed with disperse dyes, and has good coloring performance and bright colors. Its coloring performance is better than other cellulose fibers.

　3. Appearance similar to mulberry silk: The appearance and luster of acetate fiber is similar to mulberry silk, and its soft and smooth feel is also similar to mulberry silk. Its specific gravity is the same as mulberry silk, so the drape is the same as mulberry silk. Fabrics woven from acetate silk are easy to wash and dry. Acetate fabrics are mildew-free and have better elasticity than viscose fibers.

　4. The performance is close to that of mulberry silk: compared with the physical and mechanical properties of viscose fiber and mulberry silk, the strength of acetate fiber is lower, the elongation at break is larger, and the ratio of wet strength to dry strength is lower, but higher than that of viscose silk , the initial modulus is small, and the moisture regain is lower than viscose fiber and mulberry silk, but higher than synthetic fiber. The ratio of its wet strength to dry strength? Relative hook strength and knotting strength? Elastic recovery rate, etc. are similar to those of mulberry silk. big. Therefore, the performance of acetate fiber among chemical fibers is close to that of mulberry silk.

Acetate fabrics have a variety of properties that exceed those of cotton and linen fabrics, such as moisture absorption and breathability, non-stick sweat, easy to wash and dry, mildew-free, comfortable against the skin, and absolutely environmentally friendly.

Acetate fabric is not charged; it is not easy to absorb dust in the air; it can be dry-cleaned, washed in water, or hand-washed by machine below 40°C, which overcomes the disadvantages of silk and woolen fabrics that are prone to bacteria; they are dusty and can only be dry-cleaned, and woolen fabrics are also free of the problem. It is easy to be damaged by insects, but it is easy to take care of and collect. Moreover, acetate fabric has the resilience and smooth feel of woolen fabric.

Development of acetate fabrics: Acetate fiber has good dyeing properties, bright fabric colors, bright appearance, smooth and comfortable properties, but low strength. The development of acetate fabrics requires “leveraging strengths and avoiding weaknesses.” Acetate filament is widely used in clothing, furniture furnishings and decorative fabrics. Acetate filament can be used in clothing linings, shirts, sportswear, bridal gowns, children’s clothing, and T-shirts. Woven or knitted fabrics for clothing linings, skirts, sportswear, bridal gowns, children’s clothing, and T-shirts can be made of 100% acetate filament, or can be blended with acetate filament such as rayon, elastic fiber, Nylon, cotton, or linen, wool, silk polyester, etc. Velvet fabrics? Decorative silk? High-end lining silk? Grained silk? Fashion fabrics? High-end knitted T-shirt fabrics, etc. Woven furniture furnishing fabrics generally use acetate filament as the warp and cotton yarn or rayon as the weft. Most decorative fabrics are satin, and satin can also be used for ribbons, artificial flowers and ties.
