  Abstract

In order to understand the effect of the adhesive-aided ring spinning (AARS) on improving yarn performance, the relative movement of fibers on the fibrous strand through AARS-II during spinning process was studied to deduce a gathering-and-twisting mechanism of fibers. Taking advantage of the adhesion effect, adhesive solution can form a gathering to the fibers on the surface of fibrous strand. Thus, fiber ends protruding out of the fibrous strand can stick on yarn body and be twisted into the fibrous strand based on a twist stop coming from the contact during spinning process. Sodium carboxymethyl cellulose (CMC-Na), polyacrylamide (PAM) and polyvinyl alcohol (PVA) were used as adhesives in the AARS. Yarn hairiness, tensile property, abrasion resistance and yarn evenness of AARS yarns were compared and analyzed to obtain optimal concentration ranges of adhesive. Central composite design was adopted to achieve optimal match of compound adhesive solution and yarn performance. Overall, the results indicate that compound solution with CMC-Na concentration of 5.46, PAM concentration of 0.16 and PVA concentration of 0.44 will achieve a 89.6 % of reduction in harmful hairiness, a 28.5 % of growth in breaking strength and a 50.6 % of growth in abrasion resistance.
