*Penetrating agent / Wetting agent
Fiber’s moisture absorption is poor when it is untreated, mainly because there is air, oils and cotton wax inside the fiber. In order to infiltrate agents quickly along fiber, let the air go out and penetrate to the fibers, we should add surfactant which can reduce the surface tension between oil and water.
Therefore, penetration and wetting agents not only mainly used for desizing, scouring and bleaching, mercerization or pretreatment processes, but also widely used in dyeing, printing and finishing processes.
Using auxiliary: Cawet-130、Cawet-230
*Water repellent finishing agent
After processing the fabric, we can change the surface properties which have the waterproof function.
Using auxiliary: Cafinish-282
*Scouring agent / Desizing agent
Textile scouring process is the removal of natural fibers’ (cotton, wool, silk) impurities, dirt, removing residual slurry and oil in synthetic fibers. It can avoid these substances to influence the water-absorbent fabric processing.

In the textile weaving process, the warp yarns must be sized in order to avoid fiber damage caused by friction in weaving process.
Using auxiliary: Casize SA-1000、Caoil-200
*Fluorescent brightening agent
Brightener absorbs ultraviolet light, and visible light can be reflected. The visible light which emitted by fluorescent brightening agent can make fluorescence and yellow complement. Then, it will not only enhance the whitening effect but also increase the reflection of brightness in surface.
Using auxiliary: Cableach-1100PEB、Cableach-1090B
*Hydrogen peroxide stabilizer
Oxygen bleaching, retreat, boiling, and bleaching bath process, generally, the use of hydrogen peroxide is in an alkaline, and H2o2 is activated with strong oxidizing under alkaline conditions. Therefore, in order to have good control of the process of decomposition of hydrogen peroxide in oxygen bleaching, bath desizing, scouring and bleaching, and inhibit the catalytic material to reduce the fiber damage which HO2 and HO cause, and get a good bleaching effect. In addition, we should control the pH of the bleaching, and also need to add hydrogen peroxide stabilizer to slow down hydrogen peroxide decomposition rate, which makes H2O2 decomposition effective.

Leveling agent is an auxiliary which adds in the fabric and fiber dyeing, and it is able to dye evenly on the fiber’s surface and spread to the inside of the fiber, so the color of the dyed fabric showed evenly colored light and glamor.
There are two kinds of Leveling dyeing:
The first one is particularly, in the early stages of the dyeing, making dyes’ movement to fiber slows down, so dyes also slow the rate of dyeing, and the dyeing rate will sharply increase as the dyeing temperature rises up. It will make the dye focus on the partial area, so we use retarding ability to slow down dyes’ movement, and make the dye dyeing more evenly. The second is when it dyes unevenly, we make the dye move from the area which is coloring too much (color depth) to less color (light color) parts, so the dye can be evenly distributed to the fiber surface, and allowed to spread to the inside of the fiber. This leveling dyeing which makes uneven parts more even called migration.

To improve the fastness of dye, fixative agent makes the dye and the fiber more adhesive, so the dye won’t detach from the dyed fibers and contaminate the other fibers and fabrics.

After dyeing or printing, the surface of textiles has some unfixed or hydrolyzed dyes (commonly known as floating color). And if we don't let the unfixed dye remove, it will not only affect the color fastness of the product, but also influence the brightness of the color.
To eliminate these floating on the surface of the fabric, washing with water alone is useless. You must use soaping agent, so the fabric can reach its perfect rubbing fastness, wash fastness and vividness. During soaping or reduction cleaning (cleaning after PET disperse dye reduction), generally we require to add surfactant to increase washing efficiency.

*Resin finishing agent
Resin finishing agent is a finishing auxiliary which is able to make the fabric shrink-proof, anti-wrinkle and stiffness, and it also can be combined with machine finishing, making calendering, ginning, rolling more durable. Sometimes, it also can be used as cross-linking agent.
Using auxiliary: Caresin M-3、Caresin WF、Caresin PU-8711
o make the fabric touching feeling more soft, smooth and plump, apart from using the machine finishing, we can also use softener. The fabric which use resin finishing agent or some other fabric finishing agents will change the touching feeling. To overcome these drawbacks, the softener is typically added in the finishing bath.
In general, softeners have the following effects: first, it adds natural oil which is loss when it gets scouring, bleaching and other processes to make it feel more desirable. Second, to improve the strength, smoothness, touching feeling, it is attached to the natural or synthetic fibers. Third, by adding softener with oil substances, we can acquire certain characteristics in fibers, such as improving the performance of fabric, smoothness, reducing the fiber resistance of friction, making the fibers smooth, soft, and some having water-resistant effect.
