Blended yarn and spinning process thereof

Abstract

The invention discloses a blended yarn and a spinning process thereof. The blended yarn comprises the components of 50% of cotton fibers, 40% of bamboo pulp fibers and 10% of soybean protein fibers in a fiber content blending ratio, wherein the fibers are spun into the yarns through using a blending process. The yarn provided by the invention is formed through coating-mixing of the bamboo pulp fibers and the soybean protein fibers, and sliver-mixing of card slivers which are formed through performing steps of scutching, carding and combing with cotton fiber combed slivers. A compact siro-spinning technology and reasonable raw material collocation are employed so that the hairiness of the yarn can be effectively reduced and the shortcoming of poor crumple resistance of the soybean protein fibers is overcome. A mixing manner of one-time pre-drawing and triple mixing is employed, so that the blending ratio is accurate and the composition is even; and a produced single yarn is even, high in strength, few in neps and low in yarn faults.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a cotton fiber, bamboo pulp fiber, soybean protein fiber blended yarn and a spinning process thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's consumption concepts are constantly updated, and they pay more and more attention to the quality of life and living environment, and the functional requirements for clothing are also getting higher and higher, especially for antibacterial clothing. , health care, feel, quality and other aspects of the requirements are also constantly improving. Soybean protein fiber belongs to the category of regenerated plant protein fiber. It uses oil-pressed soybean meal as raw material, uses bioengineering technology to extract globulin in soybean meal, and adds functional additives to combine with nitrile, hydroxyl and other polymers. Grafting, copolymerization, a...

Problems solved by technology

Although bamboo pulp fiber has excellent antibacterial and adsorption properties, due to its poor hand feeling, skin affinity, cohesion and spinnability, it needs to be mixed with other fibers for spinning. How to choose different varieties and different proportions of other fibers? Fiber is mixed with bamboo pulp fiber, and what kind of spinning process can be used to spin out all better yarns of various properties will be technical problems to be solved by those skilled in the art
