HT Fine Textile Chemical Auxiliary Agent

[ Fixing Agent for Acid Dyes  General Information] Fixing agent for acid dyes will be deposited on the surface of the fiber, plugging the pores of acidic dyes dissolved again, thus reducing the possibility of fading, and generally improving the color fastness 1 ~ 1.5. Based on this, the solid color of the impregnation method is used. The appearance is generally brown liquid, pH value (1% water solution) 2.0-4.0, anionic, odorless, slightly special smell, taste astringent, deeper color while exposed under light and in air. Soluble in water, soluble in ethanol, acetone and glycerin, almost insoluble in ether, benzene, chloroform and petroleum ether. It has strong hygroscopicity. Decompose in 210 ~ 215 ℃, It can produce insoluble salt with copper, aluminum, iron, tin, chromium and metal salts, and each has its own special color. It is best to use soft water or add 1 g/L 6 sodium phosphate when used. [Main composition]  Sulphonate condensation polymer. [General properties...

Fixing agent textile  is one of the important textile auxiliaries in dyeing and printing industry, which can improve the color fastness of dye in fabric. On the fabric, it can form insoluble colored material with dye, thus to improve the color of washing, perspiration fastness, and sometimes can improve its sun fastness. In recent years, with the development of science and technology, dyeing and finishing technology has also been significantly improved. Due to the expansion of international textile trade and the improvement of people's living standards and environmental awareness, it's more required of textiles comfort, clean and safety. Since the 1970s, Germany first launched the "Blue Angel" plan, the world's developed countries (Japan, the United States, etc.) have passed and implemented the related laws, regulations, and rules for the various indicators of textiles. Green textiles require that in the printing and dyeing process prohibit the use of carcinogenic...

The choose of a good fixing agent  removing agent  is crucial to the repairing of the dyeing fabric. With the increasingly stringent customer requirements for dyeing quality, dyeing repair is inevitable, especially the repair of the neutral and dark color after its fixation, which is strictly required for the  fixing agent removing agent. When we add color or overdye the light color fabric, we must eliminate the interference from fixing agent. Because if we overdye the fabric with the fixing agent, the discoloration is easy to appear. So we must remove the dye fixing agent and then change color.  (For the obviously deep color fabric, the removing of the fixing agent using fixing agent removing agent is less important. Because in the process of stripping and oxygen bleaching process, the dye fixing agent is easy to be removed cleanly and evenly.) This requires the fixing agent removing agent have good performance (1) the fixing agent removing agent will not decrease t...

Lead: Some dyes can dye bright-colored fabrics and the direct dye, acid dye and other anionic water-soluble dye have wild chromatogram.  But the water-soluble groups on the dyes makes the bad wet fastness.  Fading and staining will be appeared broadly, which will cause old appearance of the fabric, and the dropped dye will stain on other fiber, and causes staining on other fiber. The reactive dye. Although, the covalent bond formed by reactive dye and fiber is quite strong, but in fact,  the non-reacted reactants and hydrolysate of dye could not completely washed from the dyed fabric, this part of dye will fade. Moreover, fabric’s covalent bond will be hydrolyzed and broken. In order to improve the fastness of the fabric, we need to fix the color. The auxiliaries that can improve the fastness is called color- fixing agent . Dye-fixing agent ‘s working principle. Dyeing different fibers, the dyeing principle and fastness is different. So the dye-fixing principle and app...

【Recommendation】Enke non-formaldehyde dye fixative agent BRIFIX AKS BASE Product brief introduction  It is compounded by quaternary ammonium compound, and have excellent fasting effect. And it can be used to in the color fastening process of activated dyeing, dyeing and printing. Application scope 1. The color fastness process of dyeing cotton, rayon fabric and woven fabric with reactive dyes  2.The color fastness process of dyeing cotton, rayon fabric and woven fabric with direct dyes  Product property 1. Non-formaldehyde, environment friendly 2. The low rate of color change and yellowing in the process of dye-fixing.  3. Do not affect the original fabric hand-feeling and hydrophilic 4. For activated and direct dye, the fastness to washing will be up to 4 grades even 4-5 grades. 5. It has the advantages of wide temperature range. In the process of drying and shaping under temperature 100-170 ℃, it has excellent color fixation effect. The fixing way  1.the mol...

Experimental result andconclusion 1.The   fixing agent ' s influence on the glossiness of dark green dye textile When we dye the dark blue textile with RemazolRR as color matching, the textile’s glossiness changes largest dealt by 1# dye fixing agent, and smallest by dealt by 4# dye fixing agent. All 4 types of dye fixing agent make the glossiness of textile  reddish and bluish to varying degrees. The changes is smaller for Remazon RGB than for remazonlRR, but dealt with the RemazonlRR will cause a little bit greenish. When we use Sumifix matching color, the color glossiness change for dye fixing agent 1# is largest compared with other 3 dye fixing agent. The dye is yellowish compared with RemazolRR, RemazolRGB, that means the shortage of blue light. 2．The fixing agent's influence on the glossiness of garnet textile When we dye the garnet textile with RemazolRR as color matching, the textile’s glossiness is bluish obviously. ...
