Performance Feature
1.This product is a formaldehyde-free environment-friendly high-quality color fixing agent. The content of free formaldehyde and released formaldehyde is zero according to National Test of GB/T2912.1 in 1998 and GB/T2912.2 in 1998.
It can be applied to cotton, linen and blended yarn. Apart from its exclusive use in color fixing technics, the product can be put with non-ionic and cationic finishing agent, to improve obviously weak wet fastness, and increase sunshine wet fastness, wet ironing and sweat fastness.
2. The soaping resistant stain of products processed by the product (for reactive dyes, direct dyes, acid dyes and sulfur dyes, etc.) can reach grade 4 to 5, dry millinggrade 4, and wetmillinggrade 3 or so.
3. RG-E903 formaldehyde-free color fixing agent is suitable for the color fixing of cotton and blended fabric, and also as resist agent for nylon, wool, cotton blended fabric; meanwhile, to improve the washing fastness and other fastness of nylon fibers acid dyes.
4. Application of this product can greatly reduce or prevent the wet fabric from moving contamination and "swelling"traces during the period of drying or partially drying.
5. The fabric, brightness, and chromatic light treated by this product cannot be affected, unnecessary to add other auxiliaries, with simple and convenient process.
6. This product has no effect or minimal on the fabric handle, stable to the general hard water, but sensitive to the presence of high concentrations of electrolytes; though stable under acidic conditions, but alkaline conditions should be avoided.
Application Process: (For reference only)
To unlock the full potential of your RG-903 formaldehyde-free fixing agent, it's pivotal to initiate the process by meticulously diluting it with water. This preparation sets the foundation for a flawless application. This crucial step must precede its seamless integration into the finishing solution, ensuring optimum performance. Be vigilant and awarethat it does not blend harmoniously with a multitude of anionic products or polymers; hence, using them simultaneously in aqueous environments is not recommended. Always incorporate the RG-903 formaldehyde-freefixing agent after the dyeing machine solution has been purged and all stained materials are meticulously cleansed, ensuring purity and perfection.
1. Dyeing Exhaust Method
The precise amount of RG-E903 to be used is dependent on both the richness of the color and the specific type of fabric being processed. The standard usage guideline advises that, when crafting a fresh solution, within the temperature window oflukewarm liquid soap around 45 to 60ºC, maintaining an ideal PH value of 5.5 to 6, the recommended dosage is outlined below (with a suggested processing time of 20-25 minutes):
Dark color:0.6----1.2%
Medium color:0.3----0.6%
Light color: 0.1----0.3%
2. Padding Method
Immerse the textiles in conditions ranging from 20 to 30 ºC,ensuring a PH value is maintained between 5.5 to 6 within the RG-903 solution for effective padding; subsequently, proceed to dry the textiles (at an optimal temperature of 100-120 ºC, ensuring the concentration of the RG-903 solution is meticulously maintained as follows:
Dark color:6.0-----12g/l
Medium color: 3.0----6.0g/l
Light color: 1.0----3.0g/l
Notes
1. After applying the color fixing agent, be aware that there might be a slight alteration in the color of the fabric or printing material. Therefore, it is advisable to conduct a preliminary test before proceeding with color matching.
2. Our RG-E903 product offers a moderate dyeing rate to suit various needs.
3. Lowering the pH value of the color fixing solution or opting for high-temperature treatment can enhance the dyeing rateof our RG- E903; in contrast, a higher pH value paired with low-temperaturetreatment will decrease the dyeing intensity and improve the overall levelling property. 4. RG-903 is compatible for use with cationic, nonionic softeners, or antistatic agents in aqueous solutions.
5. When considering the stripping process: Note that the product is quite
challenging to completely remove . In cases where it is necessaryto re-dye the fabric or yarn,it is recommended to follow this method for optimal results: use an anti-color-fixing agent : 1 ~ 3g / l; Soda: 2 ~ 3g / l; maintain at 100 ºCfor 30 minutes, followed by a rinse in warm water at 40ºC to 50 ºC twice for best results.Packaging and Storage 1. Available in a 160KG plastic drum, lined inside a bag or customized packaging as per customers' request.2. Store in a cool, dry place, ensuring a shelf life of 12 months when kept under
room temperature conditions.
3. Transport is safe as non-dangerous goods.
