What is acetate fabric? What is the difference between diacetic acid and triacetic acid? What are acetic acid products? …. Knowledge analysis of acetate fabric
The ancient “soul” under the new shell
Acetate fiber, commonly known as acetate fiber, is the world’s One of the earliest chemical fibers developed in the world, it can be traced back to more than a hundred years ago. 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 be used to dye acetate fiber. Moreover, with the increasing pressure on environmental protection, acetate fiber has environmentally friendly properties such as bio-based and degradable, and is skin-friendly and comfortable. , excellent silk-like effect, etc., are once again the focus of textile companies.
The difference between diacetic acid and triacetic acid
When it comes to 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.
According to the degree of substitution of hydroxyl group (-OH) in cellulose with 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?
Garments made of Naia™ filaments
Naia™ is the trade name of cellulose acetate, which belongs to the category of diacetate fiber. It was officially launched by the American Eastman Company in Paris, France in January 2017. roll out.

(1) Green properties of Naia™ fiber
In terms of raw materials, the raw materials of Naia™ fiber They are sourced from sustainably managed pine and eucalyptus forest farms to ensure no trees are damaged in the process, and are certified by FSC® and PEFC™ for sustainable chain of custody.
In terms of the production process, Naia™ fiber is made by a safe closed-loop process. The solvent used in the process is recovered into the system and recycled without being discharged into the environment. The production water is discharged into the water source area after being purified to meet standards, and the water body is regularly monitored to ensure the biodiversity of local rivers.
In terms of product life cycle, Naia™ fiber has a bio-based content of 59%, is biodegradable (has obtained freshwater degradability certification), and the life cycle assessment results certified by a third party comply with the ISO 14044 standard. , is an OEKO-TEX 100® Level 1 certified product and is included in the Higg Material Sustainability Index.
Naia™ has passed relevant certifications
It can be said that Naia fiber has ecological and environmentally friendly green attributes from raw materials to production to disposal.
(2) Advantages and characteristics of Naia™ fiber
In order to make every performance of Naia™ fiber well-founded, Eastman has optimized the gloss and low-cost properties of Naia™. Functions such as sensitivity, quick drying, breathability, anti-wrinkle, and easy stain removal have all been tested. The following is a brief introduction to the performance of Naia™ in terms of gloss, skin-friendlyness, and easy care.
