| Abstract: | The structure of two kinds of air jet commingled yarn of glass fiber of single yarn of the 2 yarns was analysed through microscope after hot press for single yarn,respectively.The mechanical property of four kinds of air jet commingled yarn of glass fiber/polypropylene filament was tested by using DCS-500 tester.The experimental results show that three factors(i.e.blending degree of glass fiber/polypropylene filament,the structure of glass fiber of commingled yarn,the distribution of polypropylene filament of commingled yarn)affect the mechanical properties(e.g.strength,modulus,breaking extension)of air jet commingled yarn. |
