Types of penetrants

The full name of penetrant JFC is fatty alcohol polyoxyethylene ether, which is a non-ionic surfactant. Penetrant, as the name suggests, plays a role in osmosis, and it is also a substance with fixed hydrophilic and lipophilic groups, which can be oriented on the surface of the solution and can significantly reduce the surface tension.

It has good emulsifying ability and can be used for degreasing leather. It is used for enzymatic hair removal and enzymatic softening of fur, and has the functions of penetration, degreasing and descaling.
Penetrant JFC series
There are mainly JFC, JFC-1, JFC-2, JFC-E, etc.
Fast Penetrating Agent T
Fast penetrating agent T is an anionic surfactant. In the printing and dyeing industry, it is used as a fast penetrating agent for fabrics, that is, fast and uniform. Also used as emulsifier, detergent, surfactant, etc.
Brief introduction of fast penetrating agent T
Chinese name: Fast penetrating agent T; sodium di-sec-octyl maleate sulfonate
English name: Rapid Panetrant T
Dissolution: Dissolved in water, the solution is milky white, which can significantly reduce the surface tension.
Chemical composition: dioctyl sulfosuccinate sodium salt
Type: Anion
Appearance: colorless to light yellow viscous liquid
Penetration: ≤5 seconds (1% aqueous solution, 25℃)
pH value: 5.0～7.0 (1% aqueous solution)
Fast penetrating agent T performance and application
1. Rapid penetrating agent T is easily soluble in water, the solution is milky white, not resistant to strong acid, strong alkali, heavy metal salt and reducing agent, penetrates quickly and uniformly, and has good wetting, penetration, emulsifying and foaming properties. The penetration effect is the best when the temperature is below 40 °C, and it is easier to hydrolyze when encountering alkali at high temperature. Penetrating agent T is not resistant to strong alkali and cannot be directly added to the concentrated lye solution. The lye solution should be diluted before adding penetrant T.
2. Fast penetrating agent T is a high-efficiency penetrating agent, which is used to treat cotton, hemp, viscose and its blended products. The treated fabric can be directly bleached or dyed without scouring, which can improve the dyeing defects caused by dead cotton, and the printing and dyeing. The finished fabric feels softer and fuller. When the green body is refined and bleached, it is best to return the slurry first to ensure the penetration effect.
3. If the penetrating agent T is used, if it is found that there is too much foam, a small amount of defoamer can be added, such as GP or octanol, tributyl phosphate and other defoaming agents.
4. For raw cotton dyeing; for pesticide wettable powder.
Preparation of fast penetrating agent T
It is prepared by esterification of maleic anhydride and sec-octanol at 120-140℃ under the catalysis of p-toluenesulfonic acid catalyst, and then sulfonated with sodium bisulfite.
The pH value of 1% aqueous solution is 9.5～7.0, and it is not resistant to strong acid, strong alkali, metal salt and reducing agent. Its permeability, wettability, emulsifier and foaming properties are all good.
High-efficiency penetrant
High-efficiency penetrant is a high-efficiency, low-foaming, multi-functional penetrant, which can be used as a wetting and cleaning agent in scouring, carbonization, scouring, washing, bleaching, dyeing, printing and finishing baths.
Introduction of high-efficiency penetrant 1. Appearance: colorless or slightly turbid viscous liquid;
2. Solubility: soluble in water, alcohol and other organic solvents;
3. PH value: 1.0% aqueous solution PH=5.0～7.0;
4. Ionicity: Anionic.
5. Composition: special surfactant compound
6. Ionicity: Anionic/Nonionic
7. Stability: hard water resistance, acid and alkali resistance, redox resistance
Characteristics of high-efficiency penetrants
1. It has excellent wetting and degassing properties even in cold bath liquid, which can thoroughly wet the fabrics and bobbins such as wraps, and there is little foaming.
2. It has excellent re-wetting properties for treated fabrics.
3. It has good cleaning, dispersing and degreasing functions, and is very suitable for washing away grease impurities and pigment dirt.
4. It has no effect on the enzyme, and can be used for desizing processing in the same bath with the enzyme.
5. It can quickly and evenly wet the textile fabrics to form a high liquid absorption, and at the same time, it has a certain leveling effect, which can improve the leveling property and make the color bright. The fabric should go into the bath at low temperature and then reheat.
Dosage of high-efficiency penetrant
1. It has excellent washing and degreasing ability, it will not remain on the wool after washing, nor will it turn yellow, and make the wool bulky, soft and white in color. Dosage 0.5～1.0%owf.
2. Adding 0.5-1.0% owf to the wool carbonization solution can shorten the carbonization time, reduce the amount of acid, and improve the carbonization effect.
3. Add 0.3-0.8% owf to the neutralizing solution, which can reduce the amount of alkali by about 50%.
4. Add 1~5% owf KS-T3 to the dyeing solution of loose wool and tops, which can greatly reduce the phenomenon of dyeing flowers, no white core, white flowers, and the fibers are bulky after dyeing, which brings convenience to the subsequent spinning and reduces the breakage rate.
5. For wool and wool fabric dyeing, the dosage is 0.5-2.5% owf, which can not only improve the level dyeing and dyeing properties, but also the color is pure and bright, and the color fastness is good.
6. It has good results in the scouring, dyeing and finishing of silk fabrics. The dosage is generally 0.5 to 1 g/l.
The role of high-efficiency penetrants
1. High-efficiency penetrant is mainly used for wet-process PU synthetic leather to improve the exchange speed of water and DMF;
2. The high-efficiency penetrant can rapidly increase the pores and improve the myogenicity of the PU resin film;
3. The high-efficiency penetrating agent can replace the ordinary 90 penetrating agent with the dosage of 50-30%, which can reduce the production cost;
4. The high-efficiency penetrant can highly maintain the coating thickness during solidification, and enhance the penetration and wetting properties of the PU emulsion to the base fabric.

Mercerizing penetrant
The mercerizing treatment of cotton fabrics, the reduction processing of polyester, etc., all need to use high-concentration aqueous solutions of sodium hydroxide, sodium sulfate, sodium carbonate, sodium silicate, etc., general surfactants, in concentrated alkali, inorganic salt, In the aqueous solution of some organic substances, they will salt out and separate immediately, and can no longer play the role of their surfactants. The mercerizing agent is a kind of surfactant product with high alkali resistance and excellent penetration, which makes the fabric treated by this product have good gloss and high yield, which greatly improves the treatment effect of the product and increases the added value of the product. .
