The classified acetate fiber is classified into two types of acetate fiber and triacetate fiber. Acetate fibers are generally referred to as acetate fibers. It is a kind of man-made fiber, generally made of refined cotton fleece as raw materials made of triacetate cellulose, dissolved in dichloromethane to imitate silk solution and dry spinning method, good light resistance, poor dyeing performance Generally made of short fibers, can be used as artificial hair. Strong acetate fibers can also be made.
Use Acetate fiber is not easy to catch fire and can be used to make textiles, cigarette filters, film bases, and plastic products. Currently in the United States, Europe, and Asia, acetate yarn fabrics are widely favored by consumers. The products are used in the weaving of various kinds of high-grade clothing, casual wear, pajamas, underwear, wedding dresses and accessories, and the results are very good. In the products of satin fabrics, festive ribbons and embroideries, the characteristics of acetate yarns are fully revealed.

1. The physical and mechanical properties of cellulose acetate The density of acetate fibers is smaller than that of viscose fibers and is relatively close to that of polyester fibers. Strength is the lowest among the three fibers, and the strength loss in the wet state is large, and the residual strength is approximately dry. The strong 70% is about the same as the wet strength of viscose. Therefore, be sure to take a gentle approach in the stretching and wet processing of cellulose acetate. However, the elongation at break of the cellulose acetate is higher than that of the viscose, and the elongation in the wet state is greater. Therefore, the elasticity of cellulose acetate is relatively good, similar to silk, wool. The boiling water shrinkage is low, but the high temperature treatment will affect the strength and gloss of the fiber, so the temperature should not exceed 85°C. The moisture regain is lower than viscose fiber, but much higher than polyester fiber, between viscose and polyester. In other words, cellulose acetate not only has a certain degree of water absorption, but also has the property of quickly removing after absorbing water. The softening temperature and melting point of cellulose acetate are similar to those of polyester, and have similar thermal properties as synthetic fibers; dry heat treatment under relaxed conditions does not affect the properties of the fiber. T-shirt design 2, the chemical properties of cellulose acetate Acetate fiber has good acid stability, common sulfuric acid, hydrochloric acid, and nitric acid will not affect the strength, gloss and elongation of the fiber in a certain concentration range; but it can be dissolved in Concentrated sulfuric acid, concentrated hydrochloric acid, concentrated nitric acid. Acetate fibers are very sensitive to alkaline agents, especially the diacetate fibers. After encountering strong alkalis, they are easily deacetylated. Blank t-shirts cause weight loss, and strength and modulus also decrease. Therefore, the pH of a solution treated with cellulose acetate should not exceed 7.0. Under standard washing conditions, it has strong chlorine bleach resistance and can also be dry cleaned with perchloroethylene.
3. Dyeing performance of cellulose acetate Although cellulose acetate is derived from cellulose, during the esterification process, a large part of the polar hydroxyl groups on the cellulose glucose ring is replaced with an acetyl group to form an ester. Therefore, dyes commonly used for dyeing cellulose fibers are used. Almost no affinity for cellulose acetate, it is difficult to dye. Theoretically speaking, cellulose acetate can also be dyed with direct, reactive dyes, etc., after reduction of the original hydroxyl groups by partial saponification. However, this is not feasible. In addition, since the carbonyl oxygen atom on the cellulose acetate and the residual hydroxyl group have a certain amount of negative charge, it was also experimentally dyed with a cationic dye for the diacetate fiber, but the result showed that it could only be dyed light-colored. The dyeing performance of acetate fiber is similar to that of polyester or nylon. Only the finely dispersed water-insoluble dye can enter the interior of cellulose acetate at a certain temperature and dye the fiber. The most suitable dyes for acetate fibers are disperse dyes with low molecular weight and similar dye uptake rates. In fact, the birth of the first disperse dye was also due to the need for cellulose acetate dyeing. Acetate fibers or fabrics dyed with disperse dyes are bright and bright, with good level dyeing effect, high dye exhaustion rate, high color fastness, and complete chromatograms. The dyeing process of cellulose acetate by T-shirt manufacturers has a great influence on the dyeing effect, especially the control of temperature. The lower the temperature, the easier the dyeing is. The higher the temperature, the worse the dyeing due to the fast dyeing. The following dyeing process is given for the acetate fabrics produced therewith:
Auxiliaries: chelator 0.33 g/L at 27°C, sodium dihydrogen phosphate 0.08 g/L, anionic detergent 0.07 g/L;
pH: 6.5-7.0
Temperature: 71°C Add dye, slowly warm up to 82～88°C Dyeing time: 60 min
Draining and cleaning the blended fabrics of cellulose acetate and various natural fibers or man-made fibers can be cross-stained to produce a two-color effect in one-bath dyeing. For pure cellulose acetate fabrics, they should be dyed on a wide-angle jigger or atmospheric dyeing machine to reduce the weight of fabrics. Acetated cellulose is derived from nature, but a man-made fiber with special properties, whether it is separate The use or blending with other natural, synthetic, synthetic yarns or fibers is a fabric that can bring beautiful, practical and comfortable clothing. T-shirt custom acetate yarn can also give the fabric the following characteristics:
-Natural luxury
- Silky feeling
- Comfort
- Elegant drape
- Breathability
- Reduces allergic reactions
- Biodegradation
- Bright colors do not fade
- Cross dyeing
-stable structure
3. Use of Cellulose Acetate in Lining According to the GAMA (Global Cellulose Acetate Manufacturers Association), more than 40% of the cellulose acetate consumption worldwide is used in linings. This is because cellulose acetate increases the value and quality of the lining. The value of cellulose acetate used in lining includes: Wuhan Advertising Shirt

- Special appearance effects under solar reflection. Acetate is also environmentally friendly because it is made from wood pulp that reconstitutes trees. Use of Cellulose Acetate in Apparel for the Apparel Shirts For many years, cellulose acetate has been limited to use in linings, but it has become very popular as people increase their interest in using man-made fibers in clothing.
The main end-use customers of cellulose acetate in the apparel industry focus on women's clothing. The use of cellulose acetate in the apparel industry began in the 1960s, when cellulose acetate was mainly used in blends with silk to increase strength and reduce costs. In the late 1970s, cellulose acetate was used to blend with viscose fibers to produce the famous "CADY", a dry silk crepe that was mainly used in formal dresses.
Today, cellulose acetate can be used in almost all apparel fabrics, from premium garments to high fashion. It is used in blends with natural fibers, synthetic or synthetic fibers or yarns to produce a myriad of woven fabrics such as: Chinese crepe, georgette, satin, Shandong silk, gabardine, and velvet. In knitwear, there is also a fine-textured acetic polyamide knitted fabric that incorporates Lycra's stretch knits and stretch jacquard. Designers chose these fabrics because of their feel, excellent drape, comfort, gloss and more. Its main uses: evening dresses, dresses, bridal gowns, everyday clothes, etc.
Cellulose acetate can decorate people from head to toe. Looking at many designer's clothing series, we can easily find out from it how it can be used and where it is used.
Cellulose acetate has a natural soft luster, it can perfectly absorb a variety of colors, give the fabric quality and corporate promotion and cultural jersey, so that the fabric to obtain different effects: flash, rough, bright, bump and so on.
Cellulose acetate and knitted fabrics, owing to their special properties (drapability, coolness, comfort) and some of the properties of other yarns (toughness, elasticity), make it a non-treated yarn as well as a dyed yarn. Pure spinning or blending with other natural and synthetic yarns has already achieved great success in the knitting industry.
