Method for producing high-grade knitting yarns by blending aloe fibers and cotton

Abstract

The invention relates to a method for producing high-grade knitting yarns by blending aloe fibers and cotton. Aloe fibers and cotton fibers are chosen. After being blown, carded and predrawn, the aloe fibers are combined with combed cotton silvers on a drawing frame, and after roving, spinning and winding processes, cheeses are produced. The blowing process adopts low speed, more carding, less beating, wide gauge, fewer feeding, less noil and heavy pressure; the carding process emphatically solves the carding degrees, realizes the purpose of single fibers, and reduces the fatigue damage of fibers to the max; the drawing process can uniformly blend the ingredients, reduces hooked fibers, and adopts light weight, heavy pressure, low speed, one step of predrawing and three steps of blending; the roving process adopts light weight, heavy pressure, low speed and high twist; and the spinning process adds a siro-spinning mechanism on a spinning machine, and adopts a moderate coefficient of twist, low spindle speed and low rubber-covered roller pressure. When the method is adopted, hairiness is less, anti-fuzzing and anti-pilling properties are good, the strength is high, a fabric is fluffy, soft and resilient, and produced clothing is comfortable to wear, has good warmth-keeping property, and has the effects of protecting and smoothing the skin.

Description

technical field [0001] The invention relates to a method for producing yarn for knitting by blending aloe fiber and cotton. Background technique [0002] Aloe fiber is a functional cellulose fiber made by adding aloe liquid into the fiber during spinning by high-tech means, so that the nano-aloe liquid is evenly distributed inside and outside the fiber. The chemical and physical properties of aloe viscose staple fiber are very close to that of cotton, and it has good hygroscopicity and hygroscopicity, and the fabric processed with it is particularly comfortable to wear. In the process of textile processing, blending with synthetic fibers can improve the spinnability of blended fibers and facilitate processing. At the same time, it has good dyeing performance, and can be dyed into various bright colors with a variety of dyes. It is mainly used for pure spinning or blending with cotton and other functional fibers. It is also suitable for blending with polyester and other syn...

Problems solved by technology

[0004] However, the aloe fiber has the following problems: 1. The aloe fiber is fluffy, the number of crimps is small, and the cohesion force between the fibers is small. A large amount of static electricity is easily generated during spinning, which affects the spinnability of the fiber, and is prone to sticking, rolling, and cots. 2. The strength is lower than that of cotton fiber and viscose fiber. It is more difficult to spin aloe high-count yarn than cotton fiber high-count yarn. Therefore, in the process of aloe fiber production and quality control, it is important to improve the strength of aloe yarn. Difficulties in spinning high-count yarns with aloe fibers; 3. The production of high-grade knitting yarns has high requirements for yarn evenness, fine details, thick places, neps, and hairiness. It is key to reduce fiber shortness and improve fiber uniformity; 4 , The surface of high-grade knitting yarn is smooth and easy to detach, so the problem of detachment should be solved
