Dyeing Auxiliaries
Dyeing auxiliaries are fine chemical products in the textile printing and dyeing industry applications. Dyeing agent is an important type of textile printing and dyeing auxiliaries, generally according to the classification of dyes, to name different types of dyeing agents. Dyeing auxiliaries is mainly included auxiliary for cotton, auxiliaries for polyester, auxiliaries for wool and nylon, auxiliaries for acrylic etc.
To be specific, dyeing agents include leveling agent, fixing agent, dispersing agent, fluorescent whitening agent and softener. Textile dyeing auxiliaries are essential to enhance the value-added and upgrading of textiles, they can also make the textile more contemporary, functional, and high-grade. To some extend, dyeing auxiliaries quality affects directly the fabric quality.
HT Fine Chemical thinks that the color difference of reactive dyes of cotton knitted fabrics is mainly related to dyeing auxiliaries, such as leveling agent, dispersant, anti creasing agent or fiber protection agent and dyestuffs cosolvent.
Some example chemicals used in textile dyeing:
1. Leveling agent
Light-colored reactive dyes need to use a certain leveling agent to achieve uniform dyeing, and dark not necessarily to add leveling agent. In the actual production process, three kinds of dye coloring is often use a dye as the base (the amount of 80%~90%), the other two dyes for auxiliary colors (dosage accounted for 10%~20%).
2. Anti creasing agent or fiber protection agent
Because of the characteristics of the rope-like dyeing of knitted fabrics, it will inevitably form some wrinkles in the process of pretreatment and dyeing, and add such dyeing auxiliaries to improve the feel and appearance of the cloth.
3. Dyestuffs cosolvent
Turquoise and other active dyes with larger molecular weight, its dissolution and dyeing are more difficult, in the dyeing to add the appropriate amount of cosolvent, dye molecules can be better dissolved in the dye bath, on the other hand, can make the fiber swelling, in order to facilitate the dye molecules into the internal infiltration of fiber to achieve uniform dyeing purposes.
Auxiliaries for denim sizing or garment washing
Garment washing chemicals
Garment washing process in the clothing process of a special process. The effect of washing water more and more popular, â sizing chemicalsâ is widely used in all kinds of clothing, especially the emergence of some new methods of washing, especially in daily life adds luster.
Application range:
1, woven cotton denim or blended denim made jeans, denim jacket, this is our most common washing garment washing plant.
2, pure cotton or cotton blended woven making casual trousers, casual jacket, which is now in our washing garment washing factory is more common, such as anti wrinkle anti wrinkle trousers, shirts and so on.
3, knitted pure cotton or cotton blended fabric made of casual clothing, which should be based on customer requirements to determine whether or not to wash.
4, in short, the washing clothes are generally pure natural fabrics and blended natural fabric clothing.
Objective:
1, the stability of clothing is enhanced by washing water, can shrink in advance, so that the size of stability
2, the appearance of clothing increased through different washing methods, can wash out the effects of color and texture, and deeply love the people, the added value of clothing increased.

Hand feels finishing agent
Textile finishing agents
The chemical softening is the softening agent on the fabric softening method. Effect of softening agent is to reduce yarn fabric, friction between the friction between the fibers and fabrics and the human body. Feel consolidation is to improve or get the fabric all feel as stiff, soft finishing.
The hand feels of fabric is a kind of comprehensive reaction caused by some physical and mechanical properties of fabrics by hand and skin tone, people on the fabric handle with different fabrics. The use of fiber and fabric hand feeling. Including fiber and fabric thickness, apparent specific gravity surface smoothness, touch, cold, feel soft and the degree of comprehensive factors. The finishing agents in textile are widely used in textile industry, which is very important for all the fabrics. Hand feels finishing agent is mainly included softener series, smoothing series, silicone emulsion series, silicone oil series etc.
