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

Abstract

The invention relates to an online preparation method of a hydrophobic yarn of sirofil composite spinning, and belongs to the technical field of textile processing. The method has a characteristic oflong filament winding to short fiber by using a method of sirofil composite spinning, a modification device is arranged at the operation path portion of viscose filament yarn between a filament cylinder and a front roller, and a drying device is arranged at the operating path portion of spun yarn between the front roller and a spun yarn tube. The modification device applies modifying liquid to viscose filament yarn, the drying device dries the twisted spun yarn, and the viscose filament yarn in a shape of spatial spiral is used to wrap on the outer side of cotton roving, the hydrophobic yarn is prepared by transferring the modifying liquid on the viscose filament yarn to cotton fiber in contact with the viscose filament yarn. The method changes a method of subsequent modification of an existing yarn or fabric in general, spinning is synchronized with modification, the method shortens the production cycle, saves the production cost, and simplifies the operation steps.

Description

technical field [0001] The invention relates to an online preparation method for hydrophobic yarns 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 Process Performance of Cotton / Polyester Filament Sirofil Composite Yarn". The principle of this technology is that the polyester filament is directly passed through The yarn guide device is fed from the front roller, and output at a certain distance from the front nip of the front roller and the drafted short fiber strands, and then converge at the convergence point after slight initial twisting in the twisting triangle area, and then Twisting is strengthened again and combined, and then i...
