Preparation method of super-bright and clean bleached hemp blended yarn

Abstract

The invention discloses a preparation method of a super-bright and clean bleached hemp blended yarn. The preparation method comprises the following steps of step one of selecting raw materials: respectively selecting 40-60% of wool, 25-45% of polyester and 5-25% of bleached hemp; and step two of performing pre-spinning: performing silver mixing, combing and gilling on the wool, the polyester and the hemp and then forming a rough yarn through a roving machine, performing spinning, yarn steaming and spooling to form the yarn, spraying the wool, the polyester and the hemp with wool oil and covering the wool, the polyester and the hemp with plastic paper before pre-spinning, and conducting storage for not less than 24H, wherein the proportion of the wool oil is 1: 20 and the spraying amount is0.5% -2.5%, performing silver mixing and spraying the wool oil, wherein the spraying amount is 0.5%-2.5% and the proportion of the wool oil is 1: 10, then, placing the yarn in a bobbin to be balancedfor 8H, and placing the yarn in a balance room to be balanced for 12H before pre-spinning and spooling. Compared with the prior art, the preparation method of the super-bright and clean bleached hempblended yarn has the advantages that the elasticity is good as well as the degree of finish of the surface is good, and the market competition is enhanced.

Description

technical field [0001] The invention relates to the technical field of bleached hemp polyester wool circular machine worsted yarn, in particular to a preparation method of super smooth bleached hemp blended yarn. Background technique [0002] Wool-polyester blending is one of the more common blended yarns at present. It can maintain the advantages of wool and give full play to the advantages of polyester. The blending ratio can be adjusted according to the needs of the fabric. Good elasticity and abrasion resistance under wet conditions. However, under the pressure of shortage of raw materials and environmental pollution, people began to turn their attention to non-environmental pollution and recyclable green resources. As a high-quality cellulose fiber, hemp fiber has ecological characteristics such as moisture absorption, breathability, UV protection, antistatic and antibacterial health functions, and has won the favor of consumers. However, the traditional hemp polyester...

Problems solved by technology

As a high-quality cellulose fiber, hemp fiber has ecological characteristics such as moisture absorption, breathability, UV protection, antistatic and antibacterial health functions, and has won the favor of consumers. However, the traditional hemp polyester wool blended yarn has poor elasticity, and at the same time The smoothness of the yarn surface is poor, and the market competitiveness is low
