Description

[Technical Field]

[0001] This invention relates to the field of textile technology, and in particular to a method for producing and processing coarse cotton-wool blended yarn. [Background Technology]

[0002] Wool is primarily composed of protein. Wool fibers are soft and elastic, and wool products are characterized by their full hand feel, good warmth retention, and comfortable wear. Sheep wool constitutes a significant proportion of textile raw materials. Cotton fibers have advantages such as good moisture absorption, soft hand feel, good dyeing properties, and a soft luster. Therefore, in the textile industry, wool and cotton are often blended to produce cotton-wool blended yarns. Please refer to Chinese Patent No. 201510922004.X, which discloses a method for producing cotton-wool blended yarns. This method uses cotton spinning technology to produce cotton-wool blended yarns. Currently, this cotton spinning process is the most common method used in the field to produce cotton-wool blended yarns. The drawbacks of using cotton spinning technology to produce cotton-wool blended yarns are: the yarn is relatively straight, lacks elasticity, has high twist, poor bulkiness, low elasticity, and a poor hand feel. These drawbacks limit the application of cotton-wool blended yarns.

[0003] Therefore, it is necessary to provide a method for producing coarse cotton-wool blended yarn that solves the above problems. [Summary of the Invention]

[0004] To address the aforementioned problems, the present invention aims to provide a method for producing coarse cotton-wool blended yarn with low twist, good elasticity, and good bulkiness.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a method for producing and processing a coarse cotton-wool blended yarn, comprising the following steps: A. Selecting cotton fibers with a micronaire value of 4.8 and a length of 29 mm, and selecting washed wool fibers with a count of 80; B. Dyeing the cotton fibers and wool fibers separately to form colored cotton fibers and colored wool fibers; C. Feeding the colored cotton fibers into a carding machine for carding, wherein the cylinder speed of the carding machine is 180 r / min, the licker-in speed of the carding machine is 450 r / min, and the doffer speed of the carding machine is 10 r / min; then feeding the sliver after carding into a wool carding machine for carding, wherein the cylinder speed of the wool carding machine is 80 r / min, and the working roller speed of the wool carding machine is... The speed is 100 r / min, and the doffer speed of the carding machine is 5 r / min, thus obtaining colored cotton slivers; D. The colored cotton slivers are opened by an opening machine to form loose cotton fibers; E. The loose cotton fibers are mixed with loose colored wool fibers and spun for 12 hours. During the mixing process, wool oil and antistatic agent are added. The amount of wool oil added is 0.4% of the total weight of the loose cotton fibers and loose colored wool fibers, and the amount of antistatic agent added is 2% of the total weight of the loose cotton fibers and loose colored wool fibers; F. The mixed wool and cotton are sent to a 2-stage carding machine for carding. After the 2-stage carding machine is finished, the wool and cotton are sent to a 3-stage carding machine for carding, thus making wool roving; G. The wool roving is spun into fine yarn by a spinning machine to obtain coarse cotton-wool blended yarn.

[0006] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a coarse spinning process to produce cotton-wool blended yarn, which can disrupt the fiber arrangement, thereby increasing the cohesion between fibers. In addition, the cotton-wool blended yarn produced by the production process of the present invention has low twist, high elasticity, good hand feel, and good fluffiness, which greatly improves its application range and economic value.

Detailed Implementation Methods

[0007] The following detailed description of a method for producing and processing a coarse cotton-wool blended yarn according to the present invention is provided through specific embodiments.

[0008] A method for producing a coarse cotton-wool blended yarn includes the following steps: A) Selecting cotton fibers with a micronaire value of 4.8 and a length of 29 mm, and selecting washed wool fibers with a count of 80; B) Dyeing the cotton fibers and wool fibers separately to form colored cotton fibers and colored wool fibers; C) Feeding the colored cotton fibers into a carding machine for carding, wherein the cylinder speed of the carding machine is 180 r / min, the licker-in speed of the carding machine is 450 r / min, and the doffer speed of the carding machine is 10 r / min; then feeding the sliver after carding into a wool carding machine for carding, wherein the cylinder speed of the wool carding machine is 80 r / min, and the work roller speed of the wool carding machine is 100 r / min. The carding machine operates at a doffer speed of 5 r / min to obtain colored cotton slivers; D. The colored cotton slivers are opened using an opening machine to form loose cotton fibers; E. The loose cotton fibers are mixed with loose colored wool fibers and spun for 12 hours. During the mixing process, wool-refining oil and an antistatic agent are added. The amount of wool-refining oil added is 0.4% of the total weight of the loose cotton fibers and loose colored wool fibers, and the amount of the antistatic agent added is 2% of the total weight of the loose cotton fibers and loose colored wool fibers; F. The mixed wool-cotton blend is fed into a two-stage carding machine for carding. After carding by the two-stage carding machine, the wool-cotton blend is fed into a three-stage carding machine for carding to produce roving; G.
