Cationic polyester fabric
Cationic polyester fabric
Cationic fabric is a full polyester fabric. It usually uses cationic yarn in the warp direction and ordinary polyester yarn in the weft direction. Sometimes in order to achieve a better imitation linen effect, polyester and cationic two-component fibers are blended and dyed. Use dyes respectively, ordinary dyes for polyester yarn and cationic dyes for cationic yarn. The cloth surface will have a two-color effect.
Cationically modified polyester filament is a new type of polyester product spun by introducing dimethyl isophthalate with polar group SO3Na into polyester chips. Its appearance is no different from ordinary polyester filament, but Due to the use of ion modification, not only the color absorption performance of the fiber is greatly improved, but also the crystallinity is reduced so that the dye molecules are easy to penetrate, making the fiber easy to dye, the color absorption rate is increased, and the hygroscopicity is also improved. This fiber ensures that cations are easy to penetrate Dyeing, at the same time, it can increase the micropores of the fiber, improve the fiber dyeing rate, air permeability, and moisture absorption, thereby further adapting to the silk-like transformation of polyester fiber. Through silk-like silk transformation, the fabric can be made soft, breathable, comfortable, antistatic, and durable at normal temperatures. Press-dyeable fabrics can be dyed with cationic modified multi-functional imitation wool, making the fabric soft to the touch, anti-static, anti-pilling, and co-dyed with wool at normal temperature and pressure.
The material warp yarn is made of polyester DTY100D + cationic DTY100D, and the weft yarn is interwoven with polyester DTY100D, and the two yarns are arranged in groups in the warp direction (due to different raw material components, the coloring depth varies during dyeing, and it is easy to become straight after dyeing). The warp and weft yarns are 1 /1 strip structure, interwoven on water-jet loom. The gray fabric is relaxed – scouring – alkali reduction – dyeing (disperse dyes, cationic dyes) – soft and set. The fabric has the characteristics of soft hand, not easy to fade, anti-wrinkle and wear-resistant
Fabrics woven with cationic modified fibers have the following characteristics when dyed with cationic dyes:
1. Bright color and good deep dyeing ability
2. High exhaustion rate
3. Good light fastness and smoke fading fastness
4.Dye compatibility is good when color matching
5. Stability breeds good in high-temperature dye baths
6. Contamination to other fibers including ordinary polyester fibers
7. The diffusion rate into the fiber is fast and there is no ring dyeing phenomenon
8. The dye has high stability when the pH value changes in the dye bath.
The fabric is comparable to natural fabrics in terms of wearing comfort and dyeing brightness, and is lower in price than natural silk, and can generate high added value.
Cations have particularly strong adsorption force on metal dyes, so dyeing at room temperature can be achieved. For example: real silk and polyester products must be dyed in order to make a few polyester filaments in the product colorful. However, the high-temperature dyeing performance of polyester will destroy the quality of real silk. Therefore, cationic filaments can be used instead and dyed at room temperature to ensure quality.
What are the characteristics of cationic fabrics? Are cationic fabrics good for the body? Cationic fabric is a full polyester fabric. Generally, cationic yarn is used in the warp direction and ordinary polyester yarn is used in the weft direction. When dyeing, dyes are also used respectively. Polyester yarn uses ordinary dyes and cationic yarn uses cationic dyes. The cloth surface effect will have a two-color effect. . Cationic fabrics are good for the body, and most people are wearing clothes made of cationic fabrics.
The material warp yarn is made of polyester DTY100D + cationic DTY100D, and the weft yarn is interwoven with polyester DTY100D, and the two yarns are arranged in groups in the warp direction (due to different raw material components, the coloring depth varies during dyeing, and it is easy to form straight strips after dyeing). The warp and weft yarns are 1 /1 strip structure, interwoven on water-jet loom. The gray fabric undergoes relaxation-scouring-alkali reduction-dying (disperse dyes, cationic dyes)-softening and shaping. The fabric has the characteristics of soft hand feel, not easy to fade, anti-wrinkle and wear-resistant.
Characteristics of cationic fabric
1. The name is very scientific, but it is actually polyester fabric.
2. The only difference is its dyeability.
3. It can be level-dyed with cationic dyes at 120~125 degrees (BasicorCationDyestuff), so it can be combined with polyester to form two colors (polyester must be dyed with disperse dyes at 130~135 degrees) (there are exceptions for medium and light colors)
4. Cation only refers to the suitability of the dye.eLFYC18rLp
