Abstract

The invention discloses a one-step preparation method of stranding composite yarn of fully drawn yarn / pre-oriented yarn and a device thereof. The method includes that an FDY filament device is adopted to haul part tow on the back of a spinning box to two clod godet rollers to obtain POY yarn. The left tow is hauled to two hot godet rollers to obtain FDY yarn. The two tows are winded with a speed of 2800-3200m / min after being networked through a network device to obtain multi-strands of stranding composite yarn of fully drawn yarn / pre-oriented yarn. The device is to add two cold godet rollers on the filament device. The network device and a winding device are arranged to the back of the cold godet rollers and two hot godet rollers. The invention shortens the production process, reduces theequipment occupying space, lowers the consumption of the production cost, raw materials and energies and effectively solves the technical problem of finishing the spinning and the stranding in one step. The whole process is stable. The product quality is reliable. The quality defect that monofilament in yarn is easy to appear in a composite yarn product can be completely eliminated. The yield is three times of that of the prior art. And the production efficiency can be improved greatly.

Description

technical field

[0001] The invention belongs to the technical field of synthetic fiber production technology and equipment, and specifically relates to a method and device for manufacturing fully drawn yarn / pre-oriented yarn ply composite yarn in one step after modification of conventional FDY filament equipment. Background technique

[0002] Composite yarn is a filament made of two fibers with different characteristics, such as elongation and shrinkage, which are compounded through the network. The composite silk fabric of FDY (Full draw yam, fully drawn silk) and POY (Pre-oriemed yam, pre-oriented silk) not only has the fullness and softness of simulated satin, but also has the bright tone of silk, which overcomes the disadvantages of real silk. Not washable, poor color fastness, easy to pilling and other shortcomings, the fabric made of fully drawn yarn / pre-oriented yarn plied composite yarn has a good wool feeling, and the two-color effect is particularly obvious, which ...
