The invention relates to a polygonal-
barrel tension-controllable fuzzing and pilling form and pulling
measurement device and method. The device comprises a polygonal
barrel, a friction mechanism, a tension mechanism, a
microscopy photographing mechanism, a pulling mechanism, a creel, a static raising device and a control and data
collection analysis system. The method includes the steps that after yarns are arranged and wound, by means of the polygonal
barrel rotating angle by angle
clockwise, raising, form observation and fuzzing and pilling
sample preparation are carried out synchronously angle by angle on original
yarn, ground
yarn is obtained, raising and form observation are carried out synchronously angle by angle on the ground
yarn until friction
sample preparation and form measurement of all angles are finished, and then a
microscopy form value and a
pull force curve of yarn hairness and hair balls pulled from the ultimate ground yarn which pre-tension is exerted on are measured angle by angle. The
measurement device and method are quick, easy and convenient to use, practical and accurate, can be used for fuzzing and pilling
sample preparation of the yarn, measurement of fuzzing and pilling yarn hairness, hair ball quantity and form and the pulling curve and comprehensive evaluation of anti-pilling performance of the yarn.
