New techniques of ring spinning used for woolen yarn systems

This paper reveals the new techniques applied to the ring spinning,such as compact spinning,solo spinning and sirofil spinning in detail,which have prominently ameliorated the construction of a yarn.Not only do these new techniques largely enhance appearance and physical nature of a yarn,but also can provide the high-quality original yarn for high-grade fabric and clothing production.In particular,show the enormous potentials in processing the wool fiber yarn.
