On-line preparation method of hydrophobic yarn for embedded composite spinning

Abstract

The invention relates to an on-line preparation method for hydrophobic yarn in embedded type composite spinning and belongs to the technical field of textile processing. An embedded type composite spinning method is characterized in that filaments tightly wrap short fibers; by utilizing the characteristic, a modification device is arranged at a running route of viscose filaments between a filamentdrum on a ring spinning frame and a front roller, and a drying device is disposed at the position of a spun yarn running route between the front roller and a spun yarn pipe. The modification device applies a modification liquid to the viscose filaments, the drying device dries spun yarn formed by twisting, and the hydrophobic yarn is prepared by using the viscose filaments to wrap the outer sideof rough cotton yarn in a spatial spiral shape and transferring the modification liquid on the viscose filaments to cotton fibers in contact with the modification liquid. The on-line preparation method is modified based on a method for follow-up modification on existing yarn or fabrics, causes the spinning and the modification to be performed simultaneously, shortens the production cycle, reducesthe production cost and simplifies operation steps.

Description

technical field [0001] The invention relates to an online preparation method of hydrophobic yarns for embedded composite spinning, which belongs to the technical field of textile processing. Background technique [0002] Embedded composite spinning is a new multifunctional spinning technology. For example, the Chinese public publication "Journal of Textile Science" was published in June 2010. The title of the article is "Analysis of the Principles of High-Efficiency Short-process Embedded Composite Spinning Technology". The principle of this technology is that two cotton rovings pass through the back, middle and front respectively Roller drafting, two filaments pass directly through the front roller, one of the filaments and a cotton roving form a twisted triangle area at the front nip of the front roller to spun into a spun yarn, and the other filament and another The cotton roving is spun into another spun yarn by forming another twisted triangle area at the front nip of ...

AI Technical Summary

Problems solved by technology

The disadvantage is that if you want to endow the yarn with special properties, you must add a modification process in the yarn finishing process

Its shortcoming is that the two steps of fiber modification and spinning are not synchronized, which prolongs the production cycle, complicates the production process and increases the production cost
