Preparation method of lightweight woolen yarn for slubbing

Abstract

The invention discloses a preparing method of light weight wool yarn for roving. The method comprises the first step of adding oil water and an antistatic agent with a certain proportion into a wool mixed material of wool raw materials and chemical fiber, and conducting intensive mixing, wherein the length of the wool mixed material is 5cm or above, and the wool mixed material is in a wavy shape; the second step of carding the wool mixed material in which moisture is absorbed till a spinning requirement is accorded with, controlling the clip distance between roller cylinders to be in a relaxed state till the fiber is not straightened, and then making rove with no twisting degree through winding; the third step of firstly conducting unwinding on wound rove with no twisting degree to form wool yarn, and then lengthening shaft distances in the unwinding process till no tension exists; the fourth step of feeding and winding two ends of each of the wool yarn and filament with a twisting degree; the fifth step of winding two pieces of yarn prepared in the fourth step under the condition that airflow is blown to the yarn. According to the preparing method of the light weight wool yarn for roving, innovation is made in both material selection and technology, the design and manufacturing technology of the wool yarn are a breakthrough made in traditional design application of roving wool yarn, and thus the preparing method of the light weight wool yarn for roving is worthy of popularization.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for preparing lightweight woolen yarn for slubbing. Background technique [0002] With the development of society and the continuous improvement of people's material living standards, fabrics are not only required to be beautiful, generous, and gorgeous, but more importantly, they are environmentally friendly, healthy, and comfortable. According to the requirements of existing consumers, combined with the concept of fashionable clothing design, the required fabrics have the characteristics of lightness, softness and warmth. In this field, woolen fabrics are widely used, but in the textile field, ordinary yarns are used in different spinning equipment. Under certain conditions, the handle is relatively hard and has no bulkiness. The fabric produced from the gray fabric of the loom after finishing is heavy, rigid, inelastic, and of single quality, which cannot meet the requirements...

Problems solved by technology

According to the requirements of existing consumers, combined with the concept of fashionable clothing design, the required fabrics have the characteristics of lightness, softness and warmth. In this field, woolen fabrics are widely used, but in the textile field, ordinary yarns are used in different spinning equipment. Under certain conditions, the handle is relatively hard and has no bulkiness. The fabric produced from the gray fabric of the loom after finishing is heavy, rigid, inelastic, and of single quality, which cannot meet the requirements of customers. Two relative requirements, moreover, with the increasing pressure of competition in the wool spinning industry, the profits are getting thinner and thinner. Enterprises hope to pursue low cost while ensuring quality, that is, they hope to make high wool with low wool content. The feel and texture of the wool content even have a better texture than the existing high wool content wool, so we are required to increase the technological content of the products to meet the various needs of consumers and enterprises
