Performance and uses of commonly used printing and dyeing auxiliaries
01 HA (Hyperneum oil)
Nonionic active agent, sulfuric acid compound, has strong penetrating effect.
02 NaOH (caustic soda)
Scientific name is sodium hydroxide, also The name caustic soda is highly deliquescent and can easily absorb carbon dioxide into soda ash in humid air, and can completely dissolve various animal fibers such as wool and silk. It is mainly used as a cotton desizing agent and bleaching agent in printing and dyeing.
Caustic soda should not come into contact with the skin, otherwise it will burn the skin.
03 H2O2 (hydrogen peroxide)
Scientific name: hydrogen peroxide, hydrogen peroxide It is stable in acidic environment and easy to decompose in alkaline environment. Hydrogen peroxide has strong oxidizing properties and is mainly used for bleaching fibers in printing and dyeing. It can burn the skin. Our factory uses hydrogen peroxide concentration of 50%.
04 NaCLO (Bleach)
Bleach in acidic conditions It is unstable under certain conditions and must have a pH>9 to be stable. The bleaching water has a bleaching effect on cotton fibers, and cotton fibers are mainly used for bleaching and stripping. Drift water is corrosive.
05 GLM (anti-wrinkle agent)
Dye bath anti-wrinkle The agent increases the sliding properties of dyed fibers in the dyeing machine and provides lubrication, thereby preventing creases.
CT (sodium tripolyphosphate) CT can complex Ca2+ (calcium ions) and Mg2+ (magnesium ions) in hard water to soften the water. It can disperse dirt and improve decontamination efficiency. Sodium tripolyphosphate is easily soluble in water, making the aqueous solution weakly alkaline. It is mainly used for dispersion and decontamination when softening water, refining or bleaching. It is in the form of white powder.
06 CH3COOH (HAC) Acetic acid
Acetic acid is a weak acid, It can neutralize alkalis. Acetic acid is easily mixed with water. Acetic acid is relatively mild in nature and has almost no effect on brittleness of cotton fibers. In printing and dyeing projects, its weak acidity and volatility are often used to prepare dye solutions and printing pastes. Acetic acid has a strong pungent acid smell, is corrosive, and can cause irritation, pain, and burns to the skin.
07 Na2CO3 (soda)
The chemical name is sodium carbonate. soda ash. It is easily soluble in water, and its aqueous solution is alkaline. It is mainly used as a water softener, used as a scouring agent for dyed yarn fabrics, as a direct material, vulcanization and other dye cotton dyeing auxiliary, and can be used for various purposes such as washing oil stains.
08 H2SO4 (sulfuric acid)
Concentrated sulfuric acid is water-absorbent , dehydration, strong corrosiveness and other characteristics. Sulfuric acid has a wide range of uses in printing and dyeing. It can be used for cleaning, burning cotton, neutralizing, and promoting dyeing.
09 NaCL (salt) Sodium chloride
As a dye to promote The dye is easily soluble in water, and its aqueous solution is neutral. It is a dye accelerator when dyeing with direct materials, vulcanization, reduction and other dyes. Also used as retarding agent for acid dyes (such as wool dyeing). Sodium chloride is added to the dye liquor as an electrolyte.
10 Na2SO4 (Yuanming powder)
The scientific name is sodium sulfate A kind of salt, easily soluble in water, and the aqueous solution is neutral. Yuanming powder is added to the dye liquor as an electrolyte to adjust the dye uptake rate of the fiber.
11 Na3PO4 (trisodium phosphate)
White triangular crystalline particles, easily soluble in water, the aqueous solution is alkaline, suitable for printing and dyeing Reactive dyes are mainly used to promote dyeing and fixation.
12 Na2S2O4 (insurance powder)
The scientific name is low sodium sulfite, which is A reducing agent with strong reducing ability. It is easily soluble in water and can capture oxygen in the air. It has unstable performance and is easy to decompose. The most stable acid resistance limit is PH=5 when PH=10. It is mainly used for stripping in printing and dyeing. color, bleaching (bleached wool). Insurance powder is flammable. When it catches fire, you cannot use water to put out the fire. You can only isolate the insurance powder from the air, because water will only accelerate its decomposition.
13 Reyonet200 (deoxidizing enzyme)
It is neutralized with hydrogen peroxide The agent can decompose residual hydrogen peroxide in the solution and on the cloth.
14 Rucolase (ZER) lint-eroding enzyme
For cotton The fiber cloth is delinted and the surface quality of the cloth is improved, which has a certain influence on the blasting strength of the cloth.
15 Heptol(WZB) metal complexing agent
Has dispersion It is a chelating agent with good chelating ability in the presence of Ca2+, Mg2+ and heavy metal ions.
16 Rewin(HRT) color fixing agent
Cationic color fixing agent agent, which can improve the dry and wet fastness of active materials and direct materials in cotton fiber
17 Solidol(PAI)
A fixing agent for reactive dyes and direct materials. It has no color change for direct dyes and can change the color of reactive dyes. White powder.
18 Aldtex(PON)
Use of direct dyes and vat dyes Leveling agent, penetrating agent, disperse dye dispersant. Dark brown liquid.
19 Remol (SML)
Polyester dispersion leveling agent.
20 Zetex( AR )
Disperse dye reducing agent ( It is an oxidant itself), which can protect the dyeing of disperse dyes from being affected when reducing substances exist in the high-temperature dye bath.
21 Dilatin (PON)
Polyester and its blended fabrics Dyeing accelerator, swelling agent.
22 Lyogen(PAM)
Leveling agent for nylon.
23 Bevalaid(4052) AL
Disperse level dyeing for nylon The agent can also remove floating or stained colors from the fabric.
24 Na2SO3 sodium sulfite
ThisThe product is a hydrated crystalline substance. Its main chemical property is that it has the function of returning to its original state and can deprive oxygen from other substances. It is often used to make cotton cloth in printing and dyeing.
25 Na2s sulfide alkali
Scientific name: sulfide fossil, easily soluble in Water, the aqueous solution is alkaline and is mainly used as a co-solvent for vulcanized materials. Alkali sulfide is highly corrosive to skin and eyes.
26 Sodium silicate (Na2SiO3) The aqueous solution is called water glass, which is a colorless, green or brown solid or viscous liquid. Used in the textile industry to aid dyeing, bleaching and sizing. </p
