Knitted cloth polishing

1. After the knitted fabric is scoured and bleached, it should be neutralized to make the pH between 6 and 7.5.


2. Deaeration and rinse.

3. After adding water, add EF21 into the batching tank and dilute with water, and then pump the enzyme solution into the dyeing machine.

4. If the dyeing temperature is 60℃, run the temperature to 40℃ for 10 minutes, then increase the temperature to 60℃ and pour the dye into the dyeing machine to start the dyeing process.

5. If the dyeing temperature is 80°C, first raise the temperature to 40°C and run for 30 minutes, then raise the temperature to 80°C and pour the dye into the dyeing machine to start the dyeing process.

[Storage environment] This product should be stored in a cool, ventilated and dry place below 27°C, and avoid contact with children and animals. [Safety protection] After accidentally contacting this product with eyes, rinse with tap water for more than 15 minutes.

The specific process should be adjusted by the user through the sample as appropriate.




1. If the mechanical friction and agitation can be increased, the processing effect of the product can be greatly improved.

2. Adjust the pH to 6-7 before adding the polishing enzyme.

3. After adding polishing enzyme, run for 20-30min to make it work evenly, then add salt or dye to carry out the normal dyeing process.

4. According to the different fabric characteristics and treatment conditions, it is recommended to conduct tests before use.


Recommended Process

Feel modifier

FU5730 5-15g/L

2. Regular stiffening

FU5730 20-60g/L (the specific amount is adjusted according to the effect of stiffening)

Dispensing → padding (with liquid rate 70-80%) → baking (160-170 ° C × 60-90 s).

The specific process should be adjusted by the user as appropriate

Why enzymes are used in textile industry?

      Enzymes are used in the textile industry because they accelerate reactions, act only on specific                         substrates, operate under mild conditions, are safe and easy to control, can replace harsh chemicals and           enzymes are biologically degradable.

  • What are enzymes used for in clothes?

    The specific textile enzymes used are amylases, catalase, and laccase for removing the starch, degrading excess hydrogen peroxide, textile bleaching, and lignin-degrading.

      Antibacterial agents made of silver ions, an antibacterial material or substance, can inhibit odors caused           by  the growth of microorganisms.

  • What enzyme breaks down cotton?

  • The enzymes used in the textile field are amylases for desizing of cotton and cellulases for denim finishing and biopolishing.

  • Which enzyme is used in silk industry?

  • A lipase enzyme in combination with a protease enzyme has been used for dewaxing and degumming of silk and the combined effect of dewaxing and degumming on weight loss, wettability, dye uptake, yellowing, microscopic structure, handle and lustre has been studied

  • Why enzyme process is so important in garment washing?

  • Advantages. Enzyme washing is considered more sustainable than stone washing or acid washing because it is more water efficient. Residual pumice fragments from stone washing demand a lot of water to be eliminated, and acid washing involves multiple wash cycles to produce the desired effect.
