Study on Alginate Fiber Core-Spun Yarn by Friction Spinning

Alginate fibres are difficult to spin on the traditional ring spinning machine. Friction core-spun yarn which took alginate fibers as main wrapped fibers and cotton yarn as core yarn were developed on DREF-Ⅲ. The influence of main spinning technical parameters, such as spinning speed, friction roller speed and core yarn percentage, on the yarn performances was studied by means of orthogonal experiment and the optimized technical was put forward. The results showed that the overall performance of the core-spun yarn would be better as spinning speed of 100 m/min, friction roller speed of 4000r/min, core yarn percentage of 50% respectively.
