preparation example

[0082] (1) Blowing and carding: Mix, loosen and remove impurities from the selected acrylic and carbon fiber raw materials through a cleaning machine; feed the cleaned acrylic and carbon fibers into the carding machine, The impurities and non-spinning fibers are further removed, and the sliver is obtained; wherein, in the acrylic chloride fiber carbon fiber, the weight ratio of acrylic chloride fiber to activated carbon is 85:15; the linear density of the acrylic chloride fiber carbon fiber is 3.6dtex, and the linear The density deviation is 9%, the breaking strength is 1.6cN / dtex, and the breaking elongation is 25%;

[0083] (2) Sliver making: the raw sliver is made into a uniform yarn line using a pressing roller and a coiling device, wherein the speed of the front roller is 112r / min;

[0084] (3) Drawing frame: the yarn strands are sent to the drawing frame, and the sliver is obtained through the merging-drawing-mixing-sliver-forming process; wherein, the sliver ration is 3...

Embodiment 1

[0090] (1) Weaving: weaving the carbon-incorporated yarn and covered silk obtained in the preparation example into a knitted grey fabric; the carbon-incorporated yarn is a single yarn prepared from acrylic vinyl chloride fiber-incorporated carbon fiber; the linear density of the carbon-incorporated yarn is 36.9 tex, the covered yarn is a core-spun yarn made of spandex filament and nylon filament, that is, the covered yarn is a nylon-spandex covered yarn, and its linear density is 20 / 20D. The loom used is an E12 circular weft machine, the diameter of the loom is 34 inches, the carbon-doped yarn and the covered silk are woven in a quantity ratio of 1:1, and the weaving humidity is 75%; ,like figure 1 and figure 2 shown; the E12 circular weft machine used was purchased from Quanzhou Rongtian Knitting Machinery Co., Ltd., the specific model is RT-34×54F;

[0091] (2) Open width: the cylindrical grey fabric after weaving is cut along the width-cutting line to obtain open-width p...

Embodiment 2

[0097] The only difference from Example 1 is that the linear density of the ammonia-coated silk is 20 / 30D.

[0098] The anti-virus knitted fabric obtained in this example has a benzene absorption of 4.2%, an air permeability of 305 mm / s, and a bursting strength of 515 N.

Abstract

The invention discloses a poison-proof knitted fabric and a production method thereof. The production method of anti-virus knitted fabric includes the step of weaving carbon-doped yarn and covered silk into a knitted grey fabric; wherein, the carbon-doped yarn and covered silk are woven in a quantity ratio of 1-2:1; organizational structure It is a plain stitch structure, a changed plain stitch structure or a rib structure; the covered yarn is a wrap made by using spandex filament as the core yarn and covering the spandex filament with other chemical fiber filaments except spandex. Core yarn; the carbon-doped yarn is a single yarn prepared from acrylic vinyl chloride fiber and optional other fibers. The invention can form the anti-virus knitted fabric with better anti-virus performance, better air-permeability and higher value of bursting strength by forming the carbon-doped yarn with lower strength.

Description

technical field [0001] The present invention relates to a poison-proof knitted fabric and a production method thereof. Background technique [0002] As the skin protective equipment of personal protective equipment, anti-virus clothing, anti-virus gloves, and anti-virus boot covers have always been the research focus of countries around the world. The development of equipment depends on the progress of materials. Isolation personal protective equipment is made of rubber materials. Equipment made of this type of material has strong protection, but is relatively bulky and has poor heat dissipation, which is easy to cause a large physiological load to the wearer. Breathable personal protective equipment is mainly based on carbon adsorption materials, which can absorb external toxic gases, droplet poisons, bacteria and radioactive dust through air and moisture to avoid harm to the human body. The physiological comfort of the current breathable anti-virus fabric still needs to b...
