Abstract
The invention relates to a production method of an ultra-low-shrinkage composite crystal flax fiber. The production method comprises the following steps: semi-dull FDY raw yarn and semi-dull POY raw yarn are adopted as main raw materials, the two different types of raw yarn are simultaneously introduced into a tow traction tube, a tow directly enters a yarn inlet and feed roller through a yarn guide and enters a compressed air network below the yarn inlet and feed roller, then the high-temperature shaping is carried out after the tow enters a lower hot box, the composite tow after shaping is sent out by a yarn outlet and discharge roller, and the winding and the shaping are carried out by guiding the composite tow to a spindle friction roller through the yarn guide after full oiling on an oil wheel. The production method of the ultra-low-shrinkage composite crystal flax fiber and a device thereof provided by the invention carry out the production on the traditional 1000 type polyester stretch yarn machine, and the melt direct spinning semi-dull FDY and the semi-dull POY are taken as the raw yarn for producing the composite crystal flax fiber, thereby changing the traditional process idea and leading the traditional stretch yarn machine to play a new production role. The device omits a first roller, an upper hot box, a cooling plate, a false-twister and other parts of the original device and is further provided with the yarn inlet and guide device, thereby not only changing the process route, but also saving energy.
Description
Technical field
