Abstract:

In order to solve the problems of difficulty processing and carding damage of the superfine wool, the paper analyzed the causes and solutions to thecarding damage. Through the measurement of fiber length, the number of neps, noil ratio in work space of combing, the carding process parameters were optimized, the optimal carding processing conditions were determined by TEAM-3 and orthogonal experiments as following: 2# gauge, 3# speed ratio, the tooth density of cylinder wire cloth and doffer wire cloth was 60.7 teeth/cm2 and 62.5 teeth/cm2, respectively, and top produced was 20g/m. The experimental results showed that the average loss of fiber length of the superfine wool tops derived from the optimal processing wasless than 0.5 mm. The number of neps was also decreased and yarn quality was improved.

Key words: superfine wool, carding, low-damage, optimization
