Abstract: The feasibility of spinning Solospun yarn by using the imported spinning frame which has been modified was investigated.Through analyzing the technical principle and the characteristic of Solospun,it was determined to select the home-made grooved roller to carry out the modification of the machine.The Solospun yarns were manufactured with the modified machine through optimized experiments with respect to spinning material and process conditions.The test results showed that it is feasible to produce wool yarn by Solospun technology,it can shorten production process and enhance production efficiency.Moreover,when compared with the ring spun yarn,the Solospun yarn has better strength and elongation,less hairiness,and improved wear resistance and suitable for weaving in single yarn.
