Problems solved by technology

Traditional hemp blended yarns are generally spun with hemp fibers such as hemp, flax, ramie, jute, etc., which have a coffee-like point-like appearance and have certain antibacterial and moisture-absorbing properties. The bast of the class is obtained by chemical methods such as degumming, and contains lignin, hemicellulose, pectin and other substances, resulting in high fiber rigidity, blended yarns have a tingling feeling, and the finished garment is easy to wrinkle, which affects the wearing performance and physiological senses. to challenge
At the same time, hemp is expensive, and high-grade hemp is generally used for spinning. The general price ranges from 40,000-100,000 yuan / ton, and the cost pressure is high.

Embodiment 1

[0027] Such as figure 1 As shown, the hemp-like yarn includes a hemp-like yarn main body 2 and short fibers 3, and the short fibers are divided into two parts, one part is scattered on the hemp-like yarn main body, and the other part is stuck on the hemp-like yarn main body in a gathered state. The hemp-like gathering point 1 is formed on the main body of the hemp-like yarn.

[0028] The short fibers 3 are vertical, and the length is cut to about 6 mm by a fiber cutter; about 3% of the short fibers 3 are distributed on the main body 2 of the hemp-like yarn in a uniform distribution state, and about 97% of the short fibers are In the way of winding, the accumulation glue is clamped on the said hemp-like yarn main body 2 to form the hemp-like accumulation point 1 .

[0029] The coverage of about 3% of the short fibers on the main body of the hemp-like yarn is about 85%, and the coverage of about 97% of the short fibers in the gathered state on the main body of the hemp-like yar...

Embodiment 2

[0032] A method for making hemp-like yarn, comprising the following steps:

[0033] Step 1: Carding a light brown cotton fiber on a carding machine (or combing machine, generally speaking, the straightness of the carding machine can meet the production of short fibers, and the efficiency is higher) to make cotton The slivers are cut into 6mm short fibers by using a fiber cutting machine.

[0034] Step 2: Opening the staple fiber prepared in step 1 by using a carding machine, a card beater or manual opening methods to obtain the opened staple fiber, which is in a fluffy state.

[0035] Step 3: Proportion the open staple fiber and white cotton fiber prepared in step 2 at a ratio of 20%:80%, and then process it through carding, drawing, and roving to produce a quantitative value of 3.2g / 10m and a certain twist The mixed-color roving A; the five-point gauge of the carding process is generally: 8, 7, 6, 6, 7, which can be fine-tuned in practice, and the purpose is to retain light ...

Embodiment 3

[0039] A method for making hemp-like yarn, comprising the following steps:

[0040] Step 1: Carding a light brown cotton fiber on a carding machine (or combing machine, generally speaking, the straightness of the carding machine can meet the production of short fibers, and the efficiency is higher) to make cotton The slivers are cut into 5mm short fibers by using a fiber cutting machine.

[0041] Step 2: Opening the staple fiber prepared in step 1 by using a carding machine, a card beater or manual opening methods to obtain the opened staple fiber, which is in a fluffy state.

[0042] Step 3: Proportion the open staple fiber and white cotton fiber prepared in step 2 at a ratio of 15%: 85%, and then process it through carding, drawing, and roving to make it with a quantitative value of 3.2g / 10m and a certain twist The mixed-color roving A; the five-point gauge of the carding process is generally: 8, 7, 6, 6, 7, which can be fine-tuned in practice, and the purpose is to retain ...

Abstract

The invention discloses linen-like yarn and a manufacturing method thereof. The manufacturing method includes the steps that light brown (like original linen color and slightly darker than the original linen color) cotton fiber is prepared into cotton slivers, the cotton slivers are cut into short fiber with fixed length, and opening is carried out on the short fiber to obtain fluffy short fiber; the fluffy short fiber and white cotton fiber are blended according to a certain ratio, color mixed cloth strips are manufactured through a specific cotton carding process, and color mixed rove A is manufactured through the drawing and roving processes. Another white or color mixed fiber is prepared into color mixed rove B through the processes of cotton carding, drawing and roving. Certain difference exists between the color mixed rove A and the color mixed rove B, and the double rove spinning technology of placing the color mixed rove A on the left and the color mixed rove B on the right is used for spinning to obtain linen-like yarn. The fabric formed by spinning the yarn finally has the style effect that the fabric looks like linen with naked eyes, while the actual component is cotton fiber, linen itchy feeling is avoided, the linen-like yarn can be used as knitting and weaving yarn, is manufactured into top-grade underwear, T-shirts and sportswear and is an excellent raw material for weaving fashion and fashionable fabric.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to hemp-like yarn and a manufacturing method thereof. Background technique [0002] The appearance of traditional hemp blended yarn is close to nature, bringing consumers a sense of environmental protection and nature. Traditional hemp blended yarns are generally spun with hemp fibers such as hemp, flax, ramie, jute, etc., which have a coffee-like point-like appearance and have certain antibacterial and moisture-absorbing properties. The bast of the class is obtained by chemical methods such as degumming, and contains lignin, hemicellulose, pectin and other substances, resulting in high fiber rigidity, blended yarns have a tingling feeling, and the finished garment is easy to wrinkle, which affects the wearing performance and physiological senses. come to challenge. At the same time, hemp is expensive, and high-grade hemp is generally used for spinning. The general price ranges...
