Description

A kind of production method of health-care blended vortex yarn

technical field

The invention relates to the field of spinning new technology, in particular to a production method of health-care blended vortex yarn.

Background technique

Vortex spinning is a spinning equipment (MVS) suitable for spinning pure cotton developed by Japanese Murata Company on the basis of air-jet spinning (MJS). The spinning principle of vortex spinning is that the drawn sliver is supplied to the drafting device, and the fiber bundle drawn by the roller drafting device is output from the nip of the front roller, and is moved along the spiral direction under the action of the axial airflow at the entrance of the spinning nozzle. shaped fiber guide channel into the spinning nozzle. The exit of the helical fiber guiding channel is provided with a needle-shaped twist-resistance piece, and the fiber bundle is bent at the needle so that the fiber bundle is introduced into the vortex chamber without adding twist. The front end of the fiber bundle is pulled into the yarn channel in the spindle by the dragging effect of the formed yarn, and twisted into the newly formed yarn to become the yarn core. The tail end of the fiber remains in the fiber guiding channel while being gripped by the jaws of the front roller. When the tail end of the fiber is no longer held by the nipper of the front roller, it is centrifugally affected by the air vortex in the spinning nozzle, and is no longer kept in the fiber guiding channel, but is radially dispersed by the rotating air flow at the spindle inlet Driven by the air vortex, it falls on the conical surface of the front end of the spindle, and at the same time rotates with the air vortex, wraps around the subsequent yarn, and outputs it through the yarn channel inside the spindle. The formed yarn is composed of a yarn core composed of approximately parallel untwisted fibers and helically wrapped fibers around the periphery. Therefore, vortex spinning adopts sliver feeding to directly obtain bobbins with large package structure, thereby realizing the integration of roving, spun yarn and winding processes in the traditional spinning process, thereby greatly improving spinning efficiency.

In view of this, the present invention provides a kind of production method of health-care blended vortex yarn, adopts machine-picked mixed cotton and Xinjiang long-staple cotton fiber to pass through pre-mixing, and with polyester fiber through drawing and mixing, and with apocynum fiber through opening and cleaning Mixing, so as to realize the different mixing of cotton fiber, polyester fiber and apocynum fiber in the previous process, so as to effectively improve the mixing effect of various fibers in the mixed sliver, and effectively improve the quality of the mixed sliver. Finally, vortex spinning is used in the spinning process Machine, so as to realize the direct processing of mixed strips to obtain large packages of bobbins, so as to realize the efficient production of high-quality mixed vortex yarns with health care functions.
