When active, sulfurized, direct, and indigo dyes are used to dye dark colors on cellulose fibers, their wet rubbing fastness is particularly low, especially for shades such as dark black, bright red, and turquoise, which often have a wet rubbing fastness lower than level 1. However, textiles exported to Europe and America require a wet rubbing fastness of level 3 or above. In order to improve the stability of the product to salt and alkali, and alleviate the structural deficiencies of the product itself, our company has specially developed a fully environmentally friendly wet friction fastness enhancer TY-138
【 Main Ingredients 】 Special water-based polyurethane
Product characteristics | Appearance | Light yellow to yellow semi transparent liquid (Prolonged placement will deepen) |
|---|---|---|
| Ionic Character: | Weak cation | |
| PH Value | 4.0±1.0（50g/l） | |
| Aolubility | Easy to disperse in any proportion of tap water |
Environmental Protection - This product does not contain formaldehyde or APEO, and is an environmentally friendly product that meets the requirements of the EU OEKO-TEX Standard 100;
Efficient - used for fixing treatment of cellulose fibers after dyeing; The effect of greatly improving wet friction fastness can be increased by 1-1.5 levels, reaching levels 3 or above;
Convenient - easy to use, directly dilute with water for use;
Texture - The fabric has a soft texture and has no effect on color or sunlight fastness.
【 Usage 】
Depending on the type and concentration of dye used, as well as the type and shape of the fabric being treated, the usage is as follows:
1. Immersion method (limited to water washing plants)
Dosage: TY-138:2-4% (o.w. f.) (adjusted according to the depth of chromaticity)
Bath ratio: 1:10-20
Process: Stained fabric (pH ≤ 7) → Immersion (40 ℃, time: 20-30 minutes) → Drying
2. Immersion rolling method
Dosage: TY-138:30-50g/L;
Process: dyed fabric (pH ≤ 7) → one immersion and one rolling (rolling residue rate: 80-85%) → drying
CAUTION
Please use immediately after preparation, and conduct sufficient sample testing before use. The above process is for reference only.
Can only be used alone and cannot be used in the same bath with silicone oil, softener, fixing agent, and anionic additives.
The optimal temperature control for the working fluid is between 25 ℃ and 40 ℃.
Before using the enhancer TY-138, clean the fabric thoroughly with alkali (pH ≤ 7), salt, and soap detergent.
If a large amount of foam is generated in the rolling groove after a long time of use, the foam shall be removed in time or the rolling groove shall be cleaned and the working fluid shall be changed.
Try to maintain the pH value of the working fluid within the range of 5-6.
The water used for the working fluid should be tap water with a concentration
