摘　　要：This paper studied the recycling process of cotton fibers in indigo denim fabrics.X-ray diffraction(XRD)and Fourier transform infrared(FTIR)spectroscopy were used to characterize the crystal morphology,the grain size and the chemical composition of cotton fibers after alkali treatment.The mechanical property test and the bulk length test were done.The results show that the main functional group of the obtained regenerated cotton still exists,but the absorption peak of the bound alkali appears at the wavenumber of 3701 cm-1,and the crystallinity shows a downward trend.The K/S value increases first and then decreases,and the mechanical properties and the length of the body have a certain degree of damage.This paper studied the recycling process of cotton fibers in indigo denim fabrics.
