Uster Classimate Quantum
Uster Classimate Quantum Machine automatically classify thick & thin places as well as foreign fibers in yarn on the basis of classing matrix. Quality is a pre-condition for marking of any products in the present competitive yarn world market. For maintaining proper quality of products provision for a number of textile quality control equipment for testing and analyzing raw cotton to finish fabrics including computerized equipment of Uster Classimate Quantum Machine has been considered in the project cost.
