Wool and cotton blending method and yarn thereof

Abstract

The invention discloses a wool and cotton blending method, which comprises the following steps of: preprocessing the wool before blending, opening and cleaning, carding the cotton, combing, drawing, roving, refining a yarn and spooling. A yarn which is made by blending the wool and the cotton is characterized in that the weight percentage of the wool to the cotton is as follows: the wool: the cotton=80:20. The invention has the following benefit effect that: by adopting technologies, the invention overcomes the difficulties that the roll is hardly formed on the drawing and the net is hardly formed on a carding machine when weaving a natural protein fiber with a ring spindle technology, the licking is serious in the working procedure of thickening and thinning, and the wool easily has the static to greatly increase the harmful yarn faults. The method can produce the blended yarn with the high-proportion wool and long staple combed cotton. The yarn not only keeps the heat retention of the wool, but also improves the flexibility, the air permeability and the cooldry function of the fabric, can be widely used in underclothes, and has good economic benefit and social benefit.

Description

technical field [0001] The invention relates to a blending method and yarn thereof, in particular to a wool and cotton blending method and yarn thereof. Background technique [0002] Wool is a natural protein fiber with good warmth retention. Because wool has thick fiber, high rigidity, low single strength, fluffy, and poor cohesion, semi-worsted spinning, wool spinning, and silk spinning can produce a high proportion of wool or silk products, but the spun yarn is thick and soft. Poor performance, only suitable for sweater knitting and clothing coat. The protein fiber products are spun by the ring spinning process, the yarn count is fine, the fabric is soft, and the air permeability is strong, which can be widely used in underwear, clothing fabrics, etc. However, it is difficult to spin the natural protein fiber with the ring spinning process, and it is difficult to form a roll on the blowroom and a web on the carding machine, and it is serious to wrap the skin roller in t...

AI Technical Summary

Problems solved by technology

However, it is difficult to spin natural protein fibers on the blowing machine and form a web on the carding machine when spinning natural protein fibers by the ring spinning process, and it is difficult to wrap the skin rollers in the thick and thin process.

In addition, the specific resistance of wool is relatively high, and it is easy to generate static electricity, which greatly increases harmful yarn defects.

When the wool content exceeds 50%, there are serious problems in the spinning process such as difficulty in forming laps, large uneven rice weight of cotton laps, difficulty in carding into a web, and accidental drafting of the sliver due to poor fiber cohesion, etc. The spun yarn cannot be used, let alone high-count yarn, which limits the scope of use of wool products
