Describe some problem-solving chemicals that are used in dyeing and washing.

Some problem-solving chemicals that are used in dyeing and washing

1. Acid reduction cleaning powder

Acid reduction cleaning powder is used for the regular reduction of polyester fiber or CVC's polyester part reduction cleaning; we need two baths for one reduction to neutralize the other. If it is an acid reduction, it will work in one bath, it will have good blasting strength in the fabric, weight loss will be less, and GSM will not be reduced in this chemical. It is a time-saving chemical used in the field of double-part dyeing.

2.  Shade deepening agent

If the shade is light, then the depth of its shade needs to be darkened 20% -30% without any kind of redyeing or topping, it is possible to dark. It is a silicon oil-type chemical. If the tone of the shade is right, if it is light, dark it with this silicone oil without topping any dyes. In the case of oven fabric, if there is a shade light, we do the topping. it has a chance of a spot in the fabric, so a shade-deepening agent can be used without it.

3. Fluoride-free water repellent or waterproofing agent

Fluoride-free water-repellent agents can be used in any natural synthetic fiber such as cotton, polyester, nylon, blended yarn, and fabric. If it is used in white yarn, the enzyme wash will not stain the white part after washing the yarn-dyeing garments. Almost this problem can be heard in the yarn dyeing color and staining of the white part. It may be the solution to this common problem.

4. Oligomer Inhibitor

The polyester yarn contains a type of oil that creates oligomers on the fiber surface which causes problems in shade even, dyeing pickups. Oligomer inhibitors inhibit the formation of oligomers in polyester. Dyes pick-up is reduced due to oligomer, if you use an oligomer inhibitor, you have to clean the machine well to make it oil-free. Many oils are oligomeric, such as liquid paraffin. Plasticizers are oligomeric esters that are widely used to soften thermoplastics like PVC. These can be made from monomers by combining them together or by separating them from higher fractions of unrefined oil.

5. Polyester dye-fixing agent

It enhances the colorfastness of polyester, much like the reactive fixing agent. It prevents yellow from becoming a color change and increases sublimation fastness. This problem can occur if you do not use a non-suitable softener in polyester, for this reason, you should use a suitable softener for polyester.

6. Stiffen Increasing agent

Listening to the stiffening agent, it is understood that the work of this agent will be hardening, if the fabric is stiff, some benefits will be available, it is for dimensional stability control for loose fabric and collar rib. The control of the GSM and shrinkage of the fabric.

7. GSM increasing agent for man-made fiber

This agent controls GSM, blasting strength, and shrinkage of the fabric and is equally applicable to polyester nylon viscose and many other man-made fibers. It increases strength and dimensional stability.

9. Light Fastness increasing agent

It is an anti-ultraviolet finishing agent used in dyeing and printing fabrics. It enhances light fastness solid color and printed fabric; it also enhances perspiration fastness. It is used in dyeing like direct, dispersed, reactive, and acid. It can be used in cotton, polyester, nylon, and wool. It also improves other fastness properties. If the buyer claims light fastness, you can use this chemical.

10. Turquoise blue fastness increasing fixing agent

Normally Turkish Blue's fastness is different from other dyes and its fastness properties can be enhanced with this fixing as it is bad. Another fastness is also increased due to treatment by this agent. It can be used for other dyeing shades. However, it increases rubbing, soaping, and perspiration fastness. The molecule of Turkish dyes is large so a separate fixing agent has to be used for this.

11. Hydrophilic fixing agent for reactive dyeing

Hydrophilic fixing agents basically increase the chlorine fastness so that dichlorination due to water chlorine does not occur. It can also be used to fix print fabric. And it can be fixed and printed, but the absorbency will not change or not. It enhances washes, rubbing, and sweat fastness.

12. Lycra oil removing agent

Lycra oil is a type of silicone oil that cannot be removed with a normal oil remover, due to which Lycra oil creates problems during dyeing. There is a problem with the pickup of Dyes as well as shade Un-even. For this reason, special lycra oil remover is used, this oil is not removed by the reaction of normal detergent caustic. Especially in full feeder lycra half feeder lycra, the amount of lycra in it is more, so the oil is removed with this oil remover before dying.

13. Silicon spot stripping agent

If there is a silicone spot after the fabric finish, it is very difficult to remove it and the fabric has to be stripped. It can be easily removed with a silicone strip agent. This saves both process and time.

14. Redyeing agent

The job of the redyeing agent is to dye the fabric/yarn without removing the fixing agent, softener, silicone softener, or waterproofing agent. If the softener has a fixer, it needs to be acid washed again and the fixing needs to be removed, which is a waste of time and its solution is a redyeing agent.

15. Scouring enzyme HT-DJ

It can now be used in both continuous/discontinuous processes for pretreatment instead of conventional scouring. It reduces the weight loss of the fabric by about 3% and the strength of the fabric yarn is much better. It can be a good option for knit fabric.

16. Acid-releasing agent

The acid-releasing agent keeps the pH of the bath stable while the pH of the bath increases with increasing the temperature of the bath, which is harmful to dyeing. Such as polyester, and nylon which are dyed in acid media. As the temperature rises, the pH gradually decreases.

17. Pretreatment agent

Pretreatment agent, it is possible to pretreat with a chemical without caustic and peroxide. It is possible to dye all the shades. When white shade dyeing is done, a little peroxide is required. It is possible to pretreat with anti-crease and this chemical. The strength of the fabric yarn is very high and the process loss is 2-3% less.

18. Lycra elasticity protective agent

Lycra Protective Agent, when de-sizing, squaring, and dyeing heat setting, maintains the strength of Lycra, especially denim. Garments are often rejected due to Lycra damage; Lycra protective agent saves garments from this damage.

19. Anti-back staining agent for Cotton & Polyester

If you use an anti-back staining agent, if you wash the yarn dye, or if you wash the enzyme of the stripe fabric, the high-temperature color bleeds and does not stain the white part. Even in the case of print fabric, the color does not bleed on its white part. If it bleeds, it can be removed with this chemical.

20. Environment protection organic green acid

Green acid is not an inorganic acid like sulfuric acid, it has a buffer action, and it is not volatile like acetic acid that flies. It does not form any salt like sodium acetate which is water-insoluble. So, there is no watermark in the deep shade, it evenly neutralizes the inside of the fiber. It also stays stable at high temperatures.

21. Blue Magic

If you use Blue Magic Agent, you can use Caustic only at the rate of 0.3 to 0.5 gm / l, scouring with it does not need to neutralize the hot wash after that which saves two baths. Whose time water is both saved. The strength of the fabric yarn is very high, it can be used for both continuous woven/knit.

22. Low-temperature soaping powder

Normal soaping agents work at high temperatures but some types of agents work at 60-65 degrees, for which one or two washes are required. It has no affinity to fiber or fabric. There is no affinity for light shade and print fabric.
