The influences of the three main processing parameter(friction roller speed,spinning speed and core proportion)on core-spun yarn quality are studied by means of the general rotation experiment,the optimal processing parameters producing short flax fibers cor-spun yarn on DREF-Ⅲ friction spinning machine are analyzed and god.

In this paper, we mainly studied the technique of chemical degumming bleaching and softening for flax stable which was disposaled in hackling machine, in order to meet a demand for blending with silk.
