The extended knowledge Polyester Cationic Dyeable Yarn

Polyester cationic dyeable yarn is a modified polyester, because ordinary polyester( polyethylene terephthalate) has low humidity immersion, poor dyeing performance, easy to accumulate stationary electricity, easy to filament and other failings, so generally use sulfonate as modifier modified polyester can be cationic color dyeing, or before spinning or in the cloth process to add cationic active agent to prepare modified polyester, similar yarn is called cationic yarn.

Formation and advantage of polyester cationic dyeable filament

The generally used polyester cationic dyeable filament is a new polyester product spun by introducing dimethyl isophenate with polar SO3Na into polyester slices. Its appearance is no different from ordinary polyester filament, but because of the use of ion  revision, it not only greatly improves the color immersion performance of the fiber, but also reduces the crystallinity and makes color motes easy to access. Make the fiber easy to stain, ameliorate the color immersion rate, hygroscopicity is also  bettered This fiber not only ensures cationic easy dyeing, but also increases the micropore of the fiber, improves the dyeing rate of the fiber, air permeability,  humidity immersion, so as to further acclimatize to the polyester fiber silk; By  reproduction silk can make the fabric soft permeable, comfortable,anti-static, normal temperature and pressure can be bepainted.

The introduction of cationic fabrics

Cationic fabric, that is, fabric has a kind of yarn is especially treated cationic yarn,  similar as cationic polyester yarn or cationic nylon yarn. One of the characteristics of cationic fabrics is the two- color effect, which can be used to replace some two- color yarn- dyed fabrics, therefore reducing the cost of fabrics. This is the specific of cationic fabrics, but it also limits its characteristics. In the face ofmulti-color yarn- dyed fabrics, cationic fabrics can only be replaced. Cationic fabric has bright color and is suitable for artificial fiber, but it has poor color fastness to washing and light for natural cellulose and protein fabrics. The wear and tear resistance of cationic fabric is also veritably good. After adding polyester, spandex and other artificial filaments, the strength is advanced, the pliantness is better, and the wear and tear resistance is alternate only to nylon. Cationic fabrics have some chemical parcels, similar as  erosion resistance, adulterate alkali resistance, dulling agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids, but also have some physical parcels, similar as UV resistance.

Summary of polyester cationic dyeable yarn’s characteristics

Polyester cationic dyeable yarn have the following characteristics when dyed with cationic dyes:

1. Bright color, good deep dyeing;

2. High moisture absorption performance;

3. Good fastness to sunlight and fading color;

4. Good compatibility of dye when matching color dyeing;

5. In high temperature dyeing bath, good stability;

6. Small contamination of other fibers, including ordinary polyester fibers;

7. The diffusion rate to the interior of the fiber is fast, without cyclic staining;

8. When pH value changes in the dyeing bath, the dye has high stability.
