(1) Wax emulsion can be mixed with fatening agent
Double fatliquoring agent with a small amount of emulsified wax improve and enhance the effect of fatliquoring agent, through the experiment proved that the double leather fatliquoring agent with 1% ~ 5% of the wax emulsion can improve the filling performance of fatliquoring agent, raise the permeability of fatliquoring agent in leather fiber, increase the waterproof performance of leather, the leather feels smooth and soft, plump.
(2) Wax emulsion used as additives for leather finishing
Emulsified wax is added in leather coating agent to basically fill coating, improve coating feel, wear-resisting, anti-stick and increase the effect such as luster.In the early stage, beeswax, palm wax, insect wax, white wax and Mongolian paraffin wax were used as raw materials to prepare emulsified wax. The production of these wax was limited and the price was high. In recent years, paraffin wax was continuously used as the main raw material to prepare wax emulsion for leather.Paraffin wax as the main raw material can greatly reduce the price of wax emulsion, and the use effect is not worse than natural wax, it is the main auxiliary agent for coating high-grade leather, can give leather special brightness and wax feeling.From the use can be divided into soft wax and hard wax, respectively for the bottom of leather, middle and top coat;The wax emulsions can be divided into non-ionic, anionic and cationic wax emulsions according to their ionic properties, which can be used in compatibility with finishing agents with different ionic properties.Emulsion or solid emulsion wax can be made from the dosage form.All products are water-soluble, stable emulsion, long-term storage without delamination, no floating wax.Can be applied to all kinds of leather finishing, finishing the leather luster soft and natural, feel plump and moist, can improve the leather surface friction resistance.
(3) Emulsified wax used as leather brightener, matting agent and feel agent, etc
People has two big kinds of requirement to the exterior of leather goods, it is to increase leather burnish, be like change of effect of hit smooth leather, lacquer leather, polishing leather;Another kind is not burnish feeling, make leather presents dermal feeling, natural beauty.The former needs to use brightener, the latter needs to use matt.When choosing different wax emulsions for leather top coating, some can increase leather luster or brightness, and some can produce extinction effect to present leather charm.The size of the wax emulsion is very small and its composition is relatively single. A layer of homogeneous and continuous wax film is formed on the surface of the leather. The film is very smooth on the microscopic level and has a strong reflection effect on the light wave, so as to have a sense of luster.The wax emulsion with large particle size can form a heterogeneous and uneven surface on the leather surface, which has strong scattering effect on the light wave. Scattering effect is the fundamental reason for the extinction effect of the extinction agent.
