Fatliquoring

We produce a wide range of leather fatliquors with excellent application results. They provide the leather with roundness, fullness, compaction and excellent fibre lubrication, giving a smoother leather cut.

Crude Fatliquors

 

Fatliquors that have experienced no chemical reaction or special treatment.
– Totally insoluble in water.
– Leathers with a very good round feel, filling and fullness can be obtained.
– Excellent fibre lubrication, providing a better silky cut, especially in vegetable tanned leathers.
– Good light resistance.
– Lubricated, soft feel.
During the fatliquoring process, the lubrication power can be improved by combining fatliquor mixtures. In this way better greased leathers can be obtained both on the surface and within.
Fatliquors used especially in processes that undergo strong drying and when greased or over-greased treatments are necessary.
In finishing, we can obtain a special grain lubrication when applied superficially.
As these fats remain mainly on the surface, they can improve the dying intensity and offer a certain darkness to the leather.

Sulphated fatliquors

 

Sulphated fatliquors are produced by the reaction of fats with sulphuric acid.
Leathers with a very good round feel, filling or fullness can be achieved.
Provides soft leathers with a good tight grain and elasticity.
Good light fastness.
Due to the excellent sulphated grade, QUIMSER fatliquors provide a uniform distribution of fat within the leather.
Very useful agent for all kinds of leather articles made from cow, sheep and goat.
Especially suitable for vegetable tanning leather.

Sulphited fatliquors

 

Sulphited fatliquors are produced by the reaction of fats with sodium bisulphite.
In general they give smooth and very soft leathers but no filling effect.
They provide hang hides with high inner softness.
They provide excellent stability to tanning baths and electrolytes (acid and alkaline).
Can be used in all stages of production, such as tanning or retanning.
Excellent penetration, distribution and fixation of fat.
Can be used as a single fatliquor. Specially TTK and CMT.
Complete relaxation of the fibres creates excellent milling properties.
Light fastness will depend on the type of fatliquor.
