What is triacetic acid? Where is better?
Triacetate fiber is a semi-synthetic fiber made from natural wood pulp.
It is a new type of fabric developed by Japan’s Mitsubishi Corporation that combines nature and high technology.
Triacetic acid fabric characteristics:
Triacetate fiber is a new fabric that combines nature and high technology. The raw material comes from coniferous trees and is a pure semi-artificial fiber. Its characteristics are soft hand feel, good drape, good color development and not easy to wrinkle. The ease of care has become one of the indispensable fabric materials in the busy modern society.
The main features are as follows:
1. Good thermoplasticity, able to maintain design style.

What exactly is fiber acetate?
Acetate fiber, also known as acetate fiber, is one of the earliest chemical fibers developed in the world. It is currently the second largest variety of regenerated cellulose fiber after viscose fiber. Cellulose acetate is made from cellulose pulp, which is acetylated to form cellulose esterified derivatives and then dry-spinning. According to the degree of substitution of hydroxyl group (-OH) in cellulose with acetyl group (-COCH3), it is divided into cellulose triacetate (CTA) and cellulose diacetate (CDA). When triacetate fiber is not specifically mentioned, acetate fiber generally refers to diacetate fiber.
What are the characteristics of acetate fiber?
1. Good thermoplasticity: acetate fiber softens at 200℃~230℃ and melts at 260℃. This feature makes acetate fiber thermoplastic similar to synthetic fiber. After plastic deformation, the shape will not recover, and it has The deformation is permanent. Acetate fabric has good formability, can beautify the curves of the human body, and is overall generous and elegant.
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. Acetate fabric has good thermoplasticity. Acetate fiber softens at 200°C ~ 230°C and melts at 260°C. It is similar to synthetic fiber. After plastic deformation, the shape will no longer recover, and the deformation is permanent.
3. Looks like mulberry silk: The appearance and luster of acetate fiber is similar to that of mulberry silk, and its soft and smooth feel is also similar to mulberry silk. Its specific gravity is the same as that of mulberry silk, so the drape feeling is the same as that of 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 low, but Higher than viscose silk, the initial modulus is small, 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. Not much different from mulberry silk. Therefore, the performance of acetate fiber among chemical fibers is close to that of mulberry silk.
5. Acetate fabrics are not prone to static electricity: they are not easy to absorb dust in the air; they can be dry-cleaned, washed, or machine-washed below 40°C. This overcomes the shortcomings of silk-wool fabrics that are prone to bacteria; they are dusty and can only be dry-cleaned. Woolen fabrics are easily moth-eaten, but they are easy to care for and store. Moreover, acetate fabrics have the resilience and smooth feel of woolen fabrics.
The history of acetate fiber
It has been more than a hundred years since the successful spinning of acetate fiber. Industrial production of acetate began in the early 20th century. In 1901, A. Eisingern and Bell successfully acetylated cellulose to obtain triacetate cellulose. In 1904, the German Bayor Company invented dry spinning of cellulose acetate fiber and applied for patents in France and the United Kingdom. In 1905, the discovery that diacetate could be dissolved in acetone to form a cellulose acetate solution was the first step in the development of cellulose acetate fiber. Production is guaranteed.
In the early days, acetate fiber developed very slowly because it was difficult to dye it with common natural fiber dyes, which limited its application in the textile field. It was not until 1954 to 1955 that cellulose triacetate was successfully industrially produced by certain companies in the United States, the United Kingdom, Canada, France and Germany. From 1969 to 1979, due to the rise of synthetic fibers such as nylon, polyester and polypropylene, the demand for diacetate and triacetate textile fibers continued to decline. In the United States, the demand dropped by approximately 4.20% per year, and the market fell by approximately 2.20% per year. Since the early 1980s, due to the difficulty in solving the pollution problem in viscose fiber production, some manufacturers in developed countries have closed down, which has led to a rapid increase in demand for acetate filament. In recent years, due to the continuous updating and development of product varieties and production technologies, acetate fiber has become one of the fastest growing varieties in the man-made fiber industry.
At present, there are more than 20 acetate fiber manufacturers in Belgium, Brazil, Bulgaria, Colombia, Italy, Mexico, Uruguay, Canada, Germany, CIS, Japan, the United Kingdom, and the United States, but the production technology is monopolized by a few countries. The dominant one is the American Celanese Company, whose output accounts for about half of the total output, followed by the American Eastman Chemical Company, Italian Novaceta Company, Japanese Mitsubishi Company and Teijin Company, British Acordis Company and French Rodia Company, etc. These companies total The output accounts for about 90% of the total output.
my country’s acetate fiber industry began in the 1950s. It has developed slowly, the production technology is relatively backward, and the varieties are limited to acetate tow for cigarettes. Textile acetate fiber has relied on imports over the years, mainly from four major companies: Celanese Corporation of the United States, Contex Corporation of the United Kingdom, Celanese Corporation of Canada and Mitsubishi Corporation of Japan.
How to wash clothes made of acetate fabric?
In fact, clothes made of acetic acid fabrics can be dry-cleaned or washed. The disadvantage is that they are not acid-resistant. Therefore, when washing, try to use neutral detergent or silk-wool detergent. The specific steps are as follows:
Step, first soak in clean water for 10 minutes. Water at natural temperature is fine. Do not use hot water, because hot water can easily cause stains to melt into the fibers of clothing or burn the material.
The second step is to take it out and put in detergent, stir well, and then put in the clothes to make them fully contact with the washing solution.
The third step, soak for 10 minutes. Note that if the washing instructions do not allow soaking, you should follow the instructions.
The fourth step is to stir and rub the solution repeatedly. Apply soap to the particularly dirty areas and rub gently.
The fifth step is to wash off the solution. It can be washed off after about 3 or 4 times. If it is dirty or has stubborn stains: first use a small brush dipped in gasoline and gently scrub to remove the grease, then wash it off with warm detergent solution; you can use sparkling mineral water or soda water for bartending, and pour it on It is very effective to dab the stained area with a clean cloth.
