Application of Waterborne Wax Emulsion in Leather
At present, the appearance of leather products have two major requirements, one is to increase the leather luster, such as lighting leather, paint leather, polishing effect leather; the other is not glossy, leather leather, natural beauty. The former need to use brightener, which requires the use of matting agent.
The use of different water-based wax emulsion for the top coating of leather, and some can increase the leather luster or brightness, and some can produce extinction effect of leather charm.
The composition of the water-borne wax emulsion is very small, the composition is relatively simple, in the leather surface to form a layer of uniform and continuous wax film, micro-film is very smooth, the light waves produce a strong reflection, which has a gloss sense.
The particle size of the waterborne wax emulsion, which produces the extinction effect, is large, and a non-homogeneous and microscopic uneven surface is formed on the leather surface, which produces a strong scattering effect on the light wave. The scattering effect is the root cause of the extinction effect of the matting agent.
Water-based wax emulsion can be compounded with fatliquor In the fatliquor compound with a small amount of water-based wax emulsion to improve and improve the effect of fatliquor, through the test proved to the leather fatliquor compound 1% to 5% water Wax emulsion, can improve the filling performance of fatliquor, fatliquor in the fiber to improve the permeability of the fiber to increase the waterproof performance, so that leather feel smooth, soft and plump.
