Problems solved by technology

CN108505184A discloses a processing method of permanent anti-static fabric, inserting polyacrylonitrile PAN-based carbon fiber on pure cotton yarn or polyester-cotton yarn to support gray cloth, but does not relate to the method of producing yarn from acrylonitrile fiber mixed with carbon fiber
[0005] Due to the low strength of acrylic fiber mixed with carbon fiber, it is difficult to spin acrylic fiber mixed with carbon fiber
So far, there is no report about the method of producing carbon-doped yarn from acrylic-doped fiber

Embodiment 1

[0071] (1) Cleaning and carding: the selected acrylic-chlorinated fiber mixed with carbon fiber raw material is mixed, opened and cleaned by a cotton cleaning machine; the acrylic-chlorinated fiber-doped carbon fiber after cleaning is fed into the carding machine, Further remove impurities and non-spinnable fibers, and obtain raw sliver; wherein, in the acrylic fiber mixed with carbon fiber, the weight ratio of acrylic fiber and activated carbon is 85:15; the linear density of acrylic fiber mixed with carbon fiber is 3.6dtex, the linear density The density deviation is 9%, the breaking strength is 1.6cN / dtex, and the breaking elongation is 25%;

[0072] (2) Sliver making: the raw sliver is made into a uniform yarn line using a pressure roller and a coiling device, wherein the front roller speed is 112r / min;

[0073](3) Drawing: the yarn line is sent into the drawing frame, and through the merging-drawing-mixing-striping process, the cooked strips are obtained; wherein, the coo...

Embodiment 2

[0079] The only difference from Example 1 is that, in the carbon-doped acrylic fiber, the weight ratio of acrylic fiber to activated carbon is 80:20.

[0080] The linear density of the carbon-doped yarn (single yarn) obtained in this embodiment is 28.5tex, and the linear density deviation is 2.5%, and the breaking strength of yarn is 7.5cN / tex, and the breaking strength CV value is 16%, and the amount of benzene absorption is 5.1%. Two single yarns are twisted to obtain two strands, the linear density of the strands is 59tex, the deviation of the linear density is 2.5%, the breaking strength of the yarn is 9.0cN / tex, and the CV value of the breaking strength is 12%. The twist is 450 twists / m, and the twist unevenness is 6%.

Abstract

The invention discloses a carbon-doped yarn and a production method thereof. The production method comprises the step that a rough yarn formed by modacrylic carbon-doped fibers and any other fibers isdrafted, twisted and wound to obtain a spun yarn, wherein the draft ratio is 12-22, and the speed of a front roller is 70-150r / min. By the adoption of the carbon-doped yarn and the production methodthereof, the carbon-doped yarn with better antitoxin performance and higher breaking strength can be formed by the low-strength modacrylic carbon-doped fibers.

Description

technical field [0001] The invention relates to a yarn and a production method thereof, in particular to a carbon-doped yarn and a production method thereof. Background technique [0002] Anti-virus clothing includes isolating anti-virus clothing and breathable anti-virus clothing. Isolated anti-virus clothing has strong anti-toxicity, but it is cumbersome to wear and has poor heat dissipation, which will bring a great physiological burden to the wearer. Breathable anti-virus clothing can prevent external toxic gases, spray droplets, bacteria and radioactive dust from causing harm to the human body, and can pass through air and moisture, making it more comfortable to wear. [0003] Since the 1960s, the successful development of carbon-containing fabrics has revolutionized the development of breathable anti-virus clothing. On the one hand, although carbon-containing fabrics have excellent anti-virus properties, activated carbon is easy to fall off, has poor flame retardancy...
