Preparation method for stereoscopic concave-convex auomerino full-woolen fancy yarn

Abstract

The invention discloses a preparation method for a stereoscopic concave-convex auomerino full-woolen fancy yarn. The preparation method comprises steps of selecting wool shrink-resistance processed and natural un-processed auomerino common Australasian wool as raw material, dividing various raw material traction areas of a twisting machine into a traction area (A) and a traction area (B), applying mechanical external force to fancy wool yarns under a hot and humid condition to achieve local felting and bulge; and at last, stereoscopic concave-convex auomerino full-woolen fancy yarns are achieved. With the double-traction inlets of the twisting machine, wool rough yarns of different colors and different properties are tracted and fluff is achieved via a roller fluffing machine; a loop part becomes wool yarns and the flat yarns are remained; and interval segmental fluffing wool yarn is realized; deficiencies of type singularity of a traditional twisting fibers and fancy yarns are enriched; and the stereoscopic concave-convex auomerino full-woolen fancy yarn requires no post-color dying, thereby being a green environment-friendly product.

Description

technical field [0001] The invention relates to a preparation method of all-wool fancy yarn, in particular to a preparation method of three-dimensional concave-convex merino all-wool fancy yarn. Background technique [0002] Fancy yarn has a fancy appearance for decoration, and there are many varieties and production methods. The structure of fancy yarn is composed of core yarn, decorative yarn and fixed yarn. The core yarn bears strong force and is the main yarn; the decorative yarn is twisted and wrapped around the core yarn to form an effect; the fixed yarn is wrapped around the outer periphery of the decorative yarn with the opposite twist direction to fix the pattern, but there are also cases where the fixed yarn is not used. [0003] Ordinary wool yarn can only be felted as a whole, but cannot be felted locally. In addition, the same kind of yarn cannot achieve two color effects, or similar to other yarns, the stability is not enough. The fiber of the traditional fan...
