INDIRECT DETERMINATION OF THE LOAD INTENSITY PARAMETERS ACTING ON THREADS DURING KNITTING BY MEANS OF TESTING STRUCTURE CHANGES IN SPECIAL PREPARED YARN

Abstract

Intensive loading of yarn processed by knitting influences the efficiency of the process and the quality of the knitted fabrics which are manufactured. It is frequently necessary to determine their value and eliminate the negative effect if such a necessity arises. In this work we propose an indirect method for measuring and testing loads and load changes acting on the yarn during the knitting process. By means of this method it is possible to see which parts of the stitch structure are the most loaded, and thus predict the consequences of these loads on the yarn structure. Special knitted thread-bands are used, which are photographed at the moment of knitting or scanned after the unknitting of the knitted fabric. The structure of these bands easily imprints ‘copies’ of the value and the type of loads.
