Description

A kind of high elastic vortex spinning yarn and production method thereof

technical field

The invention relates to the technical field of eddy currents, in particular to a high-elasticity eddy-current spun yarn; and also relates to a production method of the high-elasticity eddy-currently spun yarn.

Background technique

Vortex spinning is a method of using air vortex to condense and twist the fibers that are opened into a single state. into the channel into the vortex tube, forming a fiber flow. A number of air inlet holes are opened tangentially along the circumference at the appropriate position of the vortex tube, and the tail end of the vortex tube is connected to the exhaust fan through the main air duct and the filter screen, so that the negative pressure is always maintained in the vortex tube. The outside air enters the vortex tube at high speed along the tangential air intake hole. Since the airflow has a moment of momentum with the central axis of the vortex tube, a vortex is formed in the tube. A set of helical guide vanes can also be used to introduce air into the tube along the guide vanes to form a vortex. The high-speed rotating vortex moves along the axial direction of the vortex tube and rotates in the same direction as the fiber flow fed into the tangential channel to achieve axial balance. At the equilibrium position, the eddy current pushes the free-end yarn tail to make a circular high-speed rotation. The continuously fed fibers meet the moving yarn tail and condense to the yarn tail. When the free end rotates at high speed, the sliver is twisted. The efficiency of vortex spinning is low, about 30 to 50%. The thicker the yarn, the greater the frictional resistance of the free end rotation and the anti-torque moment of the twisting, and the lower the twisting efficiency. According to the principles of fluid mechanics, the pressure at the center of the vortex core is the lowest in a plane vortex. Therefore, the seed yarn can be easily sucked into the vortex tube from the center hole and start spinning during spinning. The spun yarn is actively output by a pair of output rollers, and is wound into a package by a grooved drum or a reciprocating yarn guide. In order to reduce the back embroidery and improve the production rate, the eddy current spinning machine is equipped with a self-stop device for feeding after a broken end.

The existing high-elastic vortex spun yarn has insufficient elasticity during use, which causes the yarn to break when it is used, and the existing yarn has a simple structure when it is used, which cannot make the yarn functionally diverse. , and the existing yarns are not tightly wound enough during manufacture, so that the yarns are easily off-line when they are used; thus, there is an urgent need for a high-elasticity vortex spinning yarn and a production method thereof.
