Cationic fabric is a commonly used accessory material among custom backpack manufacturers. However, it is not well-known to many people. When customers inquire about a backpack made of cationic fabric, they often ask for more information. In this article, we will provide some knowledge about cationic fabrics.
Cationic fabrics are made of polyester, with cationic filaments used in the warp and ordinary polyester filaments used in the weft. Sometimes, a blend of polyester and cationic fibers is used to achieve a better imitation of linen. The fabric for bags is dyed using ordinary dyes for the polyester filaments and cationic dyes for the cationic filaments, resulting in a two-color effect on the cloth surface.
Cationic yarn is resistant to high temperatures, which means that during the yarn coloring process, other yarns will be colored while the cationic yarn will not. This creates a two-color effect in the dyed yarn, which can be used to make various clothing and bags. As a result, cationic fabrics are produced.

1.One characteristic of cationic fabric is its two-color effect. This feature allows for the replacement of some of the color woven two-color fabrics, reducing fabric costs. However, this characteristic also limits the use of cationic fabric when faced with multi-color woven fabrics.
2.Cationic fabrics are colorful and are suitable for use as artificial fibers. However, when used in natural cellulose and protein woven fabrics, their washing and light fastness is poor.
3.The wear resistance of cationic fabrics is excellent. When polyester, spandex, and other synthetic fibers are added, the fabric exhibits higher strength, better elasticity, and abrasion resistance that is second only to nylon.
4.Cationic fabrics possess various chemical and physical properties. They are resistant to corrosion, alkali, bleach, oxidizing agents, hydrocarbons, ketones, petroleum products, and inorganic acids. Additionally, they exhibit ultraviolet resistance.
When customizing a backpack, it is recommended to use cationic fabric due to its soft feel, wrinkle and wear-resistant properties, and ability to maintain its shape. This fabric is also cost-effective. It is important to note that the language used in the original text was too informal and lacked objectivity.

Cationic dyeable polyester is a high-value fabric, which is a type of engineering plastic with excellent performance and a wide range of uses. It is widely used in fibers, films, and plastic products. Its chemical name is polybutylene terephthalate (elastic polyester), abbreviated as PBT, and it belongs to the denaturing polyester family.
The introduction of dimethyl isophthalate with a polar group SO3Na in polyester chips and spinning allows for dyeing with cationic dyes at 110 degrees, significantly enhancing the fiber’s color-absorbing properties. Additionally, the reduced crystallinity facilitates dye molecule penetration, resulting in improved dyeing and color absorption rates, as well as enhanced moisture absorption. This fiber not only ensures that it is easy to dye cationic dyes, but also increases the microporous nature of the fiber, improving its dyeing rate, air permeability, and moisture absorption. This makes it more suitable for use in polyester fiber silk simulation.
The silk simulation technique can enhance the fabric’s softness, breathability, and comfort while also making it anti-static and dyeable under normal room temperature and pressure.
