Decision's Premium Recommendations
There is a character called Wang Yangming in The Ming Dynasty. When he was away from the temple, he founded the school of the mind; when he was a parental official, he benefited the community; when the country was in crisis, he used his wisdom and courage to almost single-handedly quell the rebellion and prevent the country from being ruined by civil war. “To establish merit and virtue and speech is hardly a second choice in the last five thousand years.” Wang Yangming’s great wisdom lies in the fact that he was kinder in the face of the good people and more cunning in the face of the cunning rebels.
The world is not one-sided, it is often hermaphroditic. Just like amphoteric tanning agents among leather chemical. Amphoteric tanning agents are tanning agents that have a cationic group and an anionic group in same chemical structure – when the pH of the system is exactly the isoelectric point of the tanning agent. the tanning agent exhibits neither cationic nor anionic properties;
When the pH of the system is below the isoelectric point, the anionic group of the tanning agent is shielded and assumes a cationic character, and vice versa.
These are the two amphoteric tannins
Their isoelectric points are set to essentially close to the isoelectric point of the blue skin. So the ensuing applications show great character and convenience.
Good penetration
Firstly the pH range applicable is very wide, at low pH the blue wet skin exhibits strong cationic properties and conventional anionic materials may suffer from difficulties in penetration, inconsistent penetration of the grain and flesh surfaces and overloading of the grain surface.
However, when DESOATEN ARA & ARS is applied, it penetrates very evenly and deeply into the interior of the skin, helping to improve fullness and feel, but without thickening.
Neutralised for firm filling and grain spreading
When used after neutralisation, the anionic character is characterised by good firming and filling properties, a flat and fine grain, no aggravation of the grain and a flatter and more spacious finish.
Use when fatliquor to improve the physical strength and moisturisation of the grain surface
Used at the time of fatliquor, it helps to improve the firmness and physical strength of the grain. It also enhances the moisturisation of the touching.
Increase leather grade.
For improving the leather grade, use DESOATEN ARA & ARS to obtain a more vibrant and deep colour. Helps to improve the leather to high level.
The same applies to tanning, only by being inclusive can we broaden the possibilities of our R&D, technology and processes …….
Reason for recommendation:
Good penetration
Use after neutralization for firmness and filling, flatten the grain
Use when fatquioring to improve the physical strength and moistness of the grain
Increases the grade of the leather
Improves fullness and handle without thickening
Sustainable development has become a very important part in the leather industry, the road to sustainable development is yet long and full of challenges.
As a responsible enterprise we will carry this as our obligation and work persistently and indomitably towards the final goal.
