[0031] As an embodiment of the present invention, the mixed fiber is formed by blending sepiolite fiber and glass fiber; because sepiolite fiber has good wear resistance, and glass fiber has higher strength, but there is For the problem of poor friction resistance, blending the two fibers can obtain a blended fiber with high strength and high wear resistance. When the water-based additive is applied to synthetic leather, it can not only improve the tear resistance of synthetic leather , At the same time, it can improve the wear resistance of synthetic leather.
[0032] As an embodiment of the present invention, the phospholipid molecular solution is formed by mixing and stirring phospholipid powder with water, wherein the specific preparation method of the phospholipid powder is: adding water to crude soybean oil, fully stirring at 70-90° C. for 30 min, The phospholipids are hydrated into colloidal precipitates, and the hydrated phospholipids are obtained by continuous centrif...
