Application of Electronics in Yarn Testing Instruments in Textile

The electronics techniques have entered through many fields. In textile industry many electronic components are used and many instruments and machines are fitted with electronic measurement techniques. In this paper yarn testing instruments fitted with electronic components are discussed. How those instruments are working could be found from electronics literature. They are presented in this paper. Yarn count, yarn twist, evenness of yarns, imperfections of yarns, hairiness of yarns, single yarn strength tester, Lea strength of yarn, computerised lea strength tester, dynamic shrinkage, crimp, draw force of yarn are determined using electronic techniques.
