NaiaTM Is So Hot, What Is It?
May 21, 2019
Since September last year, from producers to brands, people have heard various introductions about NaiaTM, and even a small wave of discussion about NaiaTM has been made in the textile industry. But what exactly is NaiaTM? And listen to the breakdown below.
1. The ancient "soul" under the new shell
Acetate fiber, commonly known as acetate fiber, is one of the earliest developed chemical fibers in the world, dating back more than 100 years. In the 1930s and 1950s, cellulose acetate was widely used in the development of women's fabrics. However, the common natural fiber dyes are difficult to color acetate fibers, which limits the development of acetate fibers to a certain extent. At the same time, due to the rise of synthetic fibers, such as nylon, polyester and other fiber materials, the market for acetate fibers has been greatly impacted.
With the improvement of the dyeing process, at present, disperse dyes have been able to dye cellulose acetate, and with the increase of environmental pressure, bio-based, degradable and other environmental characteristics of acetate fiber, skin-friendly comfort, excellent silk effect, etc. Once again, it is the focus of textile companies.
2, the difference between diacetic acid and triacetic acid
When it comes to acetate, you have to say its classification. Acetate fiber is produced by using wood pulp as raw material, and cellulose is acetylated to form cellulose esterified derivative, which is then subjected to dry spinning.
Diacetate and triacetate are classified according to the degree of substitution of the hydroxyl group (-OH) in the cellulose by the acetyl group.
The diacetate fiber is formed by partial hydrolysis of the type 1 acetate, and its esterification degree is lower than that of the triacetate fiber. Therefore, the heat performance is inferior to that of the three vinegar, the dyeing performance is better than that of the three vinegar, and the moisture absorption rate is higher than that of the triacetate fiber.
Triacetate is a type of acetate which is formed without hydrolysis and has a higher degree of esterification. Therefore, the light and heat resistance is strong, the dyeing performance is poor, and the moisture absorption rate (also referred to as moisture regain) is low.
3. What is NaiaTM? What is the relationship with acetate?

NaiaTM is a trade name for cellulose acetate, which belongs to the category of diacetate. It was officially launched by the American company Eastman in January 2017 in Paris, France.

(1) Green properties of NaiaTM fiber
In terms of raw materials, NaiaTM fiber is sourced from sustainably managed pine and eucalyptus fields, ensuring that no trees are damaged during the process and has been certified by the FSC® and PEFCTM sustainable chain of custody.
In terms of production process, NaiaTM fiber is made by a safe closed-loop process, and the solvent used in the process is recycled to the system and recycled, and is not discharged into the environment. The production water is discharged into the water source after being purified and reaches the water source, and the water body is regularly monitored to ensure the biodiversity of the local river.
In terms of product life cycle, NaiaTM fiber has a biobased content of 59%, is biodegradable (has obtained freshwater biodegradable certification), and has a third-party certified life cycle assessment that meets ISO 14044 and is OEKO-TEX 100®. Level certified products are included in the Higg Material Sustainability Index.
NaiaTM has passed relevant certification
It can be said that Naia fiber has ecological and green properties from raw materials to production to disposal.
(2) Advantages of NaiaTM fiber
In order to make every performance of NaiaTM fiber available, Eastman has tested the properties of NaiaTM such as gloss, hypoallergenicity, fast drying, breathability, wrinkle resistance and easy decontamination. The following is NaiaTM. A brief introduction to performance in terms of gloss, skin-friendly and easy care.
