By adopting the method, the crystallinity of the waste terylene cloth can be reduced from 45 percent to about 40 percent, and the enzyme degradation efficiency of the originally nondirectly biodegradable waste terylene can be improved to 56 percent. Compared with the prior art, the method has the characteristics of no pollution, strong operability and greatly improved degradation rate.)
