On-line preparation method for quick-drying yarn in Sirofil composite spinning

Abstract

The invention relates to an on-line preparation method for quick-drying yarn in Sirofil composite spinning and belongs to the technical field of textile processing. In a Sirofil composite spinning method, the characteristic that filaments wrap short fibers well is utilized, a first modification device is arranged at a running route of polyester filaments between a filament drum on a ring spinningframe and a front roller, a second modification device is disposed at the position of a rough cotton yarn running route between a rough cotton yarn drum and the 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 devices apply a modification liquid to the on-line polyester filaments and the roughcotton yarn respectively, the drying device dries spun yarn formed by twisting, and the quick-drying yarn is prepared by using the polyester filaments to wrap the outer side of the rough cotton yarnin a spatial spiral shape. According to the on-line preparation 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 quick-drying yarn of Sirofill composite spinning, belonging to the technical field of textile processing. Background technique [0002] The Sirofill 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. The title of the article is "Study on the Yarn Process Performance of Cotton / Polyester Viscose Polyester Filament Sirofil Composite Yarn". The principle of this technology is viscose polyester The filaments are directly fed from the front roller through the yarn guide device, and output at a certain distance from the front nip of the front roller with the drawn cotton roving sliver. The points meet, then strengthen the twist and merge again, and then be wound onto the bobbin to form the sirofil yarn. The Sirofill composite spinni...

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 this method is to finish the fabric after it is formed, which requires the configuration of professional equipment and workshops, which increases the production cost and prolongs the production cycle
