What Is Polynosic?
Polynosic is a recycled cellulose fiber material similar to rayon.
It is also known as a modified rayon because it is a fiber that has been improved from rayon.
Rayon itself was developed in 1884 as an artificial silk yarn made from cellulose nitrate. Industrial production of rayon began in 1905, and it is still widely used today. Polynosic is said to have been developed around 1962 to enhance the functionality of rayon.
Uses of Polynosic
Polynosic is used in the same way as rayon because of its similar structure.
It is most often used for summer clothing, including linings for suits and suits, summer wear, dresses, undergarments, and stoles.
Blending with polyester improves the texture and gives it a more summery appearance.
Polynosics have a price advantage over natural fibers.
Characteristics of Polynosic
Polynosic fibers are characterized by their cross-sectional structure. Polynosic fibers have a circular, packed cross-section, which gives them properties superior to those of rayon.
Polynosic has the strength and wrinkling characteristics of rayon. Therefore, it not only combines the characteristics of rayon, such as moisture absorption, dyeability, and gloss but also has the following advantages:
- Dimensional stability. It does not stretch or shrink easily, so clothes do not shrink after washing.
- High strength. Due to its strength even with a fine fiber diameter, it is possible to make more delicate fabrics. Also, when wet, its strength is much higher than that of rayon.
- Easy to clean. The luster is the same as rayon, but even if oil stains adhere to it, they can be quickly removed by washing.
On the other hand, one demerit is that although it is less prone to wrinkling than rayon, there is a limit to how much it can be improved. For this reason, there are moves to further improve polynosic.
