The viscosity increaser of microcrystalline cellulase used in synthetic leather is prepared by using cotton pulp as raw material and waste hydrochloric acid as hydrolyst. 以棉浆为原料，废盐酸为水解催化剂，所得合成革用微晶纤锥素增粘剂的质量指标达到了德国和日本同类产品的标准。
In the presence of certain tackifier, the viscosity was decreased by big margin, the tack retention time prolonged and the final peeling strength decreased. 胶液中加入一定量的增粘剂后，粘度大幅度降低，持粘时间延长，终期剥离强度略有下降。
