Common auxiliaries in printing and dyeing and their functions (referred to in the laboratory)
Common additives and their functions
1) Penetrant: reduce the surface tension of the solution, so that the fiber can be easily wetted and penetrated
2) Detergent: It has a washing effect, makes the dirt on the fabric easy to remove, and serves as a scouring and bleaching aid.
3) Caustic soda (NaOH): strong alkali, used as a scouring agent for cotton cloth, and also as a stripping aid. After use, it can be washed away with acid
4) Soda ash (sodium carbonate Na2SiO3): used as water softener, T/C fabric scouring aid and reactive dye fixing agent
5) Baking soda (sodium bicarbonate NaHCO3): can be used as a fixing agent for reactive dyes
6) Trisodium phosphate: Na3PO4 plays the role of softening water
7) The sixth series of sodium phosphate: plays a role in softening water
8) Sodium silicate (Na2SO4): used as a scouring aid for cotton cloth, and also as a stabilizer for hydrogen peroxide bleaching
9) Hydrogen peroxide (H2O2): bleaching agent, it can bleach fabrics and can also be used as deoxidizer
10) Sodium sulfite (Na2S2O3): used as a scouring aid for cotton fabrics to prevent brittleness of cotton fabrics, and also as a residual oxygen neutralizer and dechlorinating agent
11) Sodium sulfide (Na2S): dyeing auxiliaries for sulfur dyes, which can fully reduce and dissolve sulfurized fuels
12) Sodium hypochlorite (NaClO): Used as a bleaching agent, and can also be stripped and washed
13) Table salt (NaCl) or sodium sulfate (Na2SO4): used as an accelerator for direct reactive dyes and sulfur dyes, which can increase the dye uptake rate
14) Sodium sulfide (NaS2O4): strong reducing agent, peeling and reducing cleaning effect
15) Dispersing agent (or diffusing agent): used as a dispersing fuel dyeing auxiliary, so that the disperse dye is evenly dispersed in the dyeing liquor to ensure the stability of the dyeing liquor
16) Glacial acetic acid (HAC): used as a disperse dye dyeing auxiliary to adjust the pH value, and used as a neutralizer for alkali
17) Ammonium sulfate [(NH4)2SO4]: Used as an anti-alkali agent for disperse dyes, and can also play a role in jumping PH value
18) Levelling agent: it can make the dye evenly dyed and achieve the leveling effect
19) Oxalic acid: can wash away the rust spots on the fabric
20) Fixing agent: (fixing agent Y or M) makes the direct dyes firmly adhere to the fiber, thereby improving the color fastness
21) Softener: combine with fiber or adsorb on the fiber surface to moisturize and improve the feel of fabric
22) Ping Ping O: as a direct, reactive dye leveling agent
23) Varnish: remove oil stains on fibers
24) Puffing agent: to puff the fiber and help the material to penetrate into the fiber
25) Repair agent: make the fiber absorb the color evenly, which is conducive to leveling dyeing
26) Brightener: improve the whiteness of bleached cloth
27) Defoamer: reduce or remove the foam of the solution
28) Soda: Used as a deoxidizer to remove residual oxygen
29) Taikoo oil: used as a penetrant for dyeing sulfur dyes, strong penetrating power can make sulfur black, cloth black, soft hand feeling
30) Urea: a solubilizer and also an anti-brittle agent for sulfur dyes
The company produces and sells various additives, such as moisture wicking finishing agent, ternary copolymer block silicone oil, dye guide agent, polyester bulk fiber treatment agent, benzyl benzoate, epoxy capping agent, multiple capping agent, wet Friction lifting agent, etc. Large quantity and preferential, provide samples!
