Objective evaluation of pilling resistance of fabric based on testing of characteristic parameters of fabric hairiness

For investigating the feasibility of objective evaluation of pilling resistance of fabric based on testing the change of characteristic parameters of fabric hairiness,characteristic indexes of the fabric hariness of fabric samples with different number of fuzzing and pilling were tested using a sigle-sided fabric compressing tester,and the number and average weight of the pills were analyzed; and an objective evaluation measurement for pilling performance of fabric was proposed. Studies have shown that when the fabric is pilled after being fuzzed,for different type of fabrics,the number and average weight of pills vary with the number of times of pilling; the change trends of hariness characteristic indexes along with the number of times of pilling are also different,except for decrease of hariness length due to the tangling and pilling of the hariness,other indexes take on none coincide change rule as a result of being influenced by many factors,for example,the compressibility of the pills. The pilling property of the fabric can be characterized objectively by the change rate of the hariness length before and after pilling processing,bigger change rate of the hariness length indicates that the fabric pills easilier.
