Editor’s note: Nowadays, more and more textile enterprises are using multi-component fibers to develop novel yarn to substitute conventional yarn and this has become an inevitable trend for spinners, especially those in the eastern coastal regions where there is a shortage of cotton and labor resources, in their process of readjusting product mix and upgrading production quality. Multi-component blended yarn have many advantages, as different fibers can complement each other and each fiber can play its particular role in the yarn, consequently helping enterprises diversify yarn products, extend application scope of the yarn, avoid the competition due to homogeneous products and increase profit margin. However, the spinnability and the requirements on production conditions for different multi-component blended yarn vary according to different properties of different fibers. This has posed higher requirements on enterprises’management in various aspects. So it is necessary for enterprises to timely learn information on product changing, quickly respond to the demand on market, optimize spinning process, strengthen basic management, so as to ensure consistent quality of each kind of yarn.
