STUDY ON THE METHOD FOR EFFECTIVELY QUICK DETECTING THE EVENNESS OF A KNITTED FABRIC

In this paper,the relations between the parameters of stitch structure and the needle penetra-tion force,and the method by using the needle penetration force detected to evaluate the looplength and evenness of knitted fabric indirectly are analysed and discussed.A microcomputer system with a needle sensor and author's program are used as a pick up setcombined with a data analysis system,for sampling and analysing the needle penetration forcedata.A lot of experimental research work has been done for knitted fabric of some kinds of knittedstitch and loop length.As a summary of this study,some conclusions can be drawn from the linearregression between the needle penetration force and the loop length.Then,the size and evenness ofthe loop length of knitted fabric can be indicated indirectly by detecting the value and variance ofneedle penetration force.It offers an effective method to detect and evaluate the evenness of knit-ted fabric with an efficiently high speed.
