Softness
In the hills of Ecuador grows a grass called toquilla, the stems of which can be woven into hats after some treatment. This hat was popular with the workers on the Panama Canal because it was light, soft and breathable, and was known as the “Panama hat”. You can roll the whole thing up, put it through a ring and unfold it without a wrinkle. So it’s usually packaged in a cylinder and rolled up when not being worn, making it easy to carry around.
One of Bernini’s most celebrated sculptures is the magical “Pluto Snatching Persephone”, where Bernini created what is probably the “softest” marble in human history, expressing the supreme beauty of marble in its “softness”.
Softness is the basic perception that gives humans a sense of identity. Humans like softness, perhaps because it does not bring us harm or risk, but only security and comfort. If all sofas in American homes were Chinese solid wood funniture, there must not be so many couch potatoes, right?
Therefore, for leather, softness has always been one of the most recognised properties by consumers. Whether it is clothing, furniture, or carseat.
The most effective product for the softness in the leather-making is fatliquor.
The softness of the leather is the result rather than the aim of fatliquor, which is to prevent the fibre structure from re-adhesion during the drying (dehydration) process.
But in any case, the use of fatliquors, especially certain natural ones, can result in very soft and comfortable leathers. However, there are also problems: most natural fatliquors have an unpleasant smell or yellowing because of the large number of unsaturated bonds in their structure. Synthetic fatliquors, on the other hand, do not suffer from this problem, but they are often not as soft and comfortable as required.
Decision has one product that solves this problem and achieves extraordinary performance:
DESOPON USF Super soft synthetic fatliquor
We’ve made it as soft as it can be -
Of course, although the softness is very good, when judged manually, the crust feels a little less full than the lecithin fatliquor product.
So we also tried to solve this problem and made a good solution.
We have randomly selected a classic traditional sofa leather recipe which uses 18% fatliquor, of which over 60% is lecithin fatliquor.
Using a wet-blue of US cow, to divide, half of the original recipe was used; half of the original recipe was adapted to the fatliquor recipe as follows.
2% DESOPON SK70*
4% DESOPON DPF*
12%DESOPON USF
The exact same dry and milling was then used. The final blind test was scored by five technicians in four performance areas and then averaged, with the following results：
Compared to the conventional recipe, the DESOPON USF with polymer fatliquor is very similar in terms of softness and sponge, but has significant advantages in terms of fullness and colour vibrancy.
We believe that such a direction of performance and process ideas for fatliquor can be of little help and inspiration to our customers producing soft leathers.
We don't go for the perfect, but we try to make the best. This is the original intention that Decision has always maintained in its research and development and technology application exploration
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.
