Abstract:

In order to solve the problems on hard conversion from convenitional ring hairy yarn to knitted fabric, high rigidity for fabric made of conventional compact smooth yarns, a tandem half-open type multiple condensed spinning method was proposed, then the spinning principle and yarn formation mechanism thereof were theoretically analyzed. The theoretical analysis results indicated that the multiple condensed spun yarn is featured with tight outer layers and soft interior structures. Based on the theoretical analysis, conventional ring, conventional compact and multiple condensed spun yarns were used to produce knitted fabrics with the same machine and knitting parameters, respectively. The knitted fabrics were comparatively investigated in terms of compression resilience, air permeability, moisture permeability, pilling resistance, wear resistance and dyeing performance, respectively. The results moisture permeability and pilling resistance after the comparison with conventional ring yarn fabrics. The fabric drapability, compression resilience and dyeing ability of multiple condensed spun yarns are much better than those of conventional compact yarns.
