Abstract

The invention discloses a method for preparing wula sedge blended fasciated yarn. The method comprises the steps that firstly, wula sedge fibers are obtained through boiling, combing, third soda boiling and softening treatment; the clipped wula sedge fibers of 45 mm to 50 mm and cotton are mixed, opened, combed, drawn and subjected to rotor spinning according to the mass ratio being 70 / 30-10 / 90 to form a core yarn material, a roller type combing machine is adopted for combing, and repeated opening and combing are adopted to improve the uniformity of subsequent yarn; finally, a wrapping process is used for wrapping the wula sedge / cotton blended core yarn, two or more pieces of pure cotton yarn, modal yarn, wool yarn and the like are combined and wound around one barrel side by side to serve as external fasciated yarn, and the ratio of the rotating speed of a hollow ingot to output roller speed is 500 to 900. By means of preparation of the wula sedge blended fasciated yarn, the application field of the wula sedge fibers with the heat preservation and bacterium resisting performance can be widened.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a preparation method of ulagrass blended wrapping yarn. Background technique [0002] Ulagrass, as a material with thermal and antibacterial properties, has been gradually developed and utilized by people and used in the textile field. [0003] At present, the extraction of ulagrass fiber mainly refers to the extraction process of hemp fiber, mainly by chemical method, and the basic properties of ulagrass fiber can be compared with some hemp fibers, but the further in-depth research of ulagrass fiber is still at the stage. preliminary research stage. Wang Junyou, Wang Chunhong and others only mixed ulagrass fiber with other fibers, and prepared nonwoven fabrics through opening, carding, acupuncture and other processes, which were applied to mat products. However, no research has been carried out on the preparation of higher-grade Ulagrass products. In order to bring out the...
