Abstract

A jute/hemp/cotton blended yarn comprises three types of fiber of jute, hemp and cotton and is characterized in that the weight of the hemp fiber accounts for 10-40 percent by weight of the total weight of the jute, the hemp and the cotton fiber. The fineness difference between the hemp fiber and the jute fiber and the fineness difference between the hemp fiber and the cotton fiber are both small. When being blended, the hemp fiber of the blended yarn can be cohered with the jute fiber and can also be cohered with the cotton fiber, thereby enhancing the cohesion among different types of fiber; and the spun blended yarn has better breaking strength. The invention discloses the content range of the added hemp fiber which can lead the breaking strength of the yarn to be more satisfactory during the blending of the jute fiber/cotton fiber with different weight percentages.

Description

technical field [0001] The invention relates to a blended yarn, in particular to a blended yarn containing jute, hemp and cotton fibers. Background technique [0002] With the improvement of human material living standards, people have shifted more attention from the durability of clothing to the requirements for comfort, because hemp fiber has better moisture absorption, low static electricity and good antibacterial properties. , hemp textile clothing fabrics are more and more popular. The fabrics of existing hemp textiles and clothing mainly refer to flax, ramie raw materials or fabrics made by blending / interweaving such raw materials with other fibers such as cotton, wool, chemical fiber, silk, etc. However, due to the higher prices of flax and ramie, hemp textiles have not been widely used. And jute is the world's second largest cellulose fiber after cotton, its price is low, and compared with flax and ramie, it has better hygroscopicity and drapability, and its antiba...
