What is acetate fabric? What is the difference between diacetic acid and triacetic acid? What are acetic acid products? …. Knowledge analysis of acetic acid fabrics
The ancient “soul” under the new shell
Acetate fiber, commonly known as cellulose acetate, is one of the earliest chemical fibers developed in the world, dating back more than a hundred years. From the 1930s to the 1950s, acetate fiber was widely used in the development of women’s clothing fabrics. However, common natural fiber dyes are difficult to color acetate fiber, which limits the development of acetate fiber to a certain extent. At the same time, the rise of synthetic fibers, such as nylon, polyester and other fiber materials, has greatly impacted the acetate fiber market.
With the improvement of dyeing technology, disperse dyes can now dye acetate fiber. Moreover, with the increasing environmental pressure, the bio-based fiber acetate , biodegradable and other environmentally friendly properties, as well as skin-friendly comfort and excellent silk-like effect, are once again the focus of textile companies.
The difference between diacetic acid and triacetic acid
mentioned Acetate fiber, we have to talk about its classification. Acetate fiber is produced from wood pulp as raw material. The cellulose in it is acetylated to form cellulose esterified derivatives, which are then dry-spun.
Based on the degree to which the hydroxyl group (-OH) in cellulose is replaced by an acetyl group, it is divided into diacetate fiber and triacetate fiber.
Diacetate fiber is formed after partial hydrolysis of type 1 acetate, and its degree of esterification is lower than that of triacetate fiber. Therefore, the heating performance is inferior to triacetate fiber, the dyeing performance is better than triacetate fiber, and the moisture absorption rate is higher than triacetate fiber.
Triacetate fiber is a type of acetate formed without hydrolysis, and its degree of esterification is high. Therefore, it has strong light and heat resistance, poor dyeing performance, and low moisture absorption rate (also called moisture regain).
What is Naia™? What does it have to do with acetate?
Garment made of Naia™ filament
Naia™ It is the trade name of cellulose acetate, which belongs to the category of cellulose diacetate. It was officially launched by the American Eastman Company in Paris, France in January 2017.
