On-line preparation method for hygroscopic yarn in Sirofil composite spinning method

Abstract

The invention relates to an on-line preparation method for hygroscopic yarn in a Sirofil composite spinning method and belongs to the technical field of textile processing. In the Sirofil composite spinning method, the characteristic that filaments wrap short fibers well is utilized, a modification device is arranged at the position of a polyester filament running route between a filament drum ona 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 amodification liquid to polyester filaments, the drying device dries spun yarn formed by twisting, and the hygroscopic yarn is prepared by using the polyester filaments to wrap the outer side of roughcotton yarn in a spatial spiral shape. According to the method, the spinning and the modification are performed simultaneously. Compared with a conventional method of adding a modification process after spinning or weaving, the on-line preparation method shortens the production cycle, reduces the production cost and simplifies operation steps.

Description

Technical field [0001] The invention relates to an on-line preparation method of moisture-absorbing yarn of a Sirofil composite spinning method, which belongs to the technical field of textile processing. technical background [0002] Sirofil spinning spinning method is a new spinning method developed on the basis of Siro spinning. For example, the Chinese public publication "Journal of Xi'an Institute of Engineering Science and Technology" was published in April 2007, and the article title is "Study on the Process Performance of Cotton / Polyester Polyester Filament Sirofil Composite Yarns". The principle of this technology is that polyester filaments pass directly through The yarn guide device is fed from the front roller, and is output at a certain distance from the drafted short fiber strands at the front nip of the front roller. After being slightly twisted for the first time in the twisting triangle, they merge at the convergence point, and then The twist is strengthened aga...

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

The disadvantage is that the conventional method is to modify the yarn after yarn forming, which complicates the production process, increases the production cost and prolongs the production cycle.
