Leather Soften Enzyme
---acidic protease GR-M401
Direct using acidic protease finished enzyme
Rich product--used in many acidic tanning operations
Promote the absorption of Tanning Auxiliaries
Remove redundant scrimp, improve softness and increase skin acreage.
Acidic protease GR-M401 is an acidic proteolytic enzyme, can used as a
leather soften auxiliary. Used in poor quality leather, promote smoothness
and increase skin acreage. It can be used in acidic process, such as acid pickling,
dual-face and wet blue reforming process.
Temperature & PH range
When using leather enzyme, product properties are based on technologies,
like PH value, temperature, time, natural characteristics of substrate and enzyme
activity, and so on. All the factors have influence on product using effects.
Acidic soften enzyme GR-M401 function temperature is same as typical soften
process (about 25-38ºC), even the enzyme optimum activity effected temperature
is 40-50ºC. Acidic soften enzyme has a wide effected PH range, which is 3.5-6.5,
the optimum is 4.5. Due to versatility of enzyme itself, acidic soften enzyme can
be used in other leather processes, such as, wet blue reforming process.
It can improve quality of wet-blue leather, improve leather softness.
Acidic soften enzyme GR-M401 is a finished enzyme which can be used directly.
Can be added based on requirements, or mixed using with other auxiliaries as a
soften material. Recommended dosage: 0.5%-1.5% (calculate by leather weight), the technology is: in peeled or deacidification, add in the remaining 60-90 minutes; in alkalization process, 90-120minutes before using retanning agent, use the products;
or use in advance in the neutralization process.
Leather diversity and different resources, local production operating environment
all can affect leather enzyme using effects, recommend to do small testing under
same production operating environment, then do mass production.This can avoid
damage and influence to hide because of excessive or different process.
Particularly to less quality leather, process technology and time must be more accurate.
Storage: 5-25 degree dry room temperature (product should be sealed in occluded devices and avoid exposure to moisture and high humidity)
Shelf life: shelf life is 12 months under correct storage condition. If stored in high temperature or high moisture for long time, should increase dosage to reach desired effects.
