Abstract

The invention discloses a preparation method of ulagrass blended wrapping yarn. First, "boiling + carding + three times of alkali boiling + softening treatment" is used to obtain ulagrass fiber; then the ulagrass fiber cut to 45-50 mm and cotton are mixed and opened at a mass ratio of 70 / 30-10 / 90, Carding, drawing, and rotor spinning into core yarn materials, in which a roller carding machine is used for carding, and repeated opening and carding are used to improve the uniformity of subsequent yarns; Cotton blended core yarn is used for wrapping, and two or several pieces of pure cotton yarn, modal yarn, wool yarn, etc. are combined and wound on a bobbin in parallel as outer wrapping yarn. The speed ratio of hollow spindle speed and output roller is 500-900. The preparation of ulagrass blended wrapped yarn will broaden the application field of ulagrass fiber with thermal insulation and antibacterial properties.

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...
