【摘要】 A new type of alkali-soluble polyester/cotton blended yarns was used to knit a compact knitted fabric on a circular weft knitting machine,treated with 5 g/L Na OH solution for 60 min at a temperature of 100 ℃,and the polyester was completely dissolved. The dissolved polyester could be polymerized again by a polycondensation reaction.After the cotton fibers were opened and combed,the length and mechanical properties of the cotton fibers were tested.The physical and mechanical properties of the separated cotton fibers were good. The chemical structure and crystallinity were analyzed by Fourier transform infrared( FTIR) spectroscopy and X-ray diffraction( XRD) analysis.It could be seen that the chemical structure of cotton fibers was almost unchanged after treatment,and the crystallinity decreased slightly. It provides some reference for the separation and recycling of waste polyester/cotton fabrics.
