Problems solved by technology

[0003] In the existing antistatic fabrics, there is a problem of poor antistatic effect, often due to repeated washing friction or long-term exposure to low-humidity acid and alkali environments, which easily lead to the decline of antistatic ability, greatly The normal use of antistatic fabrics is limited; and in the preparation process of existing antistatic fabrics, it is difficult to remove natural impurities and slurry, which will affect subsequent processing and product quality; In the process of treatment, incomplete wetting and incomplete absorption of modified antistatic additives often occur, which will affect the use effect of antistatic fabrics

Embodiment 1

[0031] An antistatic fabric, each raw material is respectively 45% polyester fiber, 20% cotton fiber, 20% silk fiber, 7.5% aluminum fiber and 7.5% graphite fiber by weight percentage;

[0032] The antistatic fabric is prepared according to the following steps:

[0033] 1) Raw material removal treatment: firstly remove the particulate impurities mixed in polyester fiber, cotton fiber, silk fiber, aluminum fiber and graphite fiber by hand, then loosen them by hand and put them into an ultrasonic cleaning machine for cleaning , and the working frequency is controlled at 25KHz, and the cleaning time is controlled at 30 minutes, then it is taken out and put into a drying room at 60 degrees for drying to obtain clean and fluffy fibers;

[0034] 2) Blending processing: the clean and fluffy fibers obtained in step 1) are drawn, roved and spun to obtain spun yarns, and then the spun yarns are wound on the warp beam and coil of the shuttle loom respectively. Then, the warp yarn on the ...

Embodiment 2

[0042] An antistatic fabric, each raw material is respectively 50% polyester fiber, 25% cotton fiber and 25% silk fiber by weight percentage;

[0043] The antistatic fabric is prepared according to the following steps:

[0044] 1) Raw material removal treatment: first remove the particulate impurities mixed in polyester fiber, cotton fiber and silk fiber by hand, then loosen them by hand and put them into an ultrasonic cleaning machine for cleaning, and the working frequency is controlled at 25KHz, the cleaning time is controlled at 30 minutes, then take it out and put it in a drying room at 60 degrees for drying to get clean and fluffy fibers;

[0045] 2) Blending processing: the clean and fluffy fibers obtained in step 1) are drawn, roved and spun to obtain spun yarns, and then the spun yarns are wound on the warp beam and coil of the shuttle loom respectively. Then, the warp yarn on the warp beam and the weft yarn on the reel are interwoven by the shuttle on the shuttle lo...

Embodiment 3

[0052] A kind of antistatic fabric, with embodiment 1.

[0053] The antistatic fabric is prepared according to the following steps: the same as in Example 1.

[0054]Wherein, the preparation method of the modified antistatic auxiliary agent in step 4) is as follows: first, after the reaction kettle is preheated to 100 degrees and kept for 5 minutes, lauryl alcohol and sodium hydroxide are added thereto, and it is mixed and stirred at this temperature. Afterwards, vacuumize and dehydrate until the anhydrous distills out in the reactor, and inject nitrogen to remove the residual air in the reactor, then feed ethylene oxide into it, pressurize to 0.15Mpa, and control the reaction temperature at 150 After reacting for 120 minutes, cool the obtained feed liquid to 90 degrees, then filter it with a 100-mesh stainless steel sieve while it is still hot, and then neutralize the filtrate with potassium hydroxide aqueous solution, let it stand and cool to obtain a modified antistatic Au...

Abstract

The invention discloses an antistatic fabric. The antistatic fabric is prepared from the following raw materials including, by weight, 40%-50% of polyester fibers, 15%-25% of cotton fibers, 15%-25% ofsilk fibers, 5%-10% of aluminum fibers and 5%-10% of graphite fibers. According to the antistatic fabric, the aluminum fibers, the graphite fibers, the polyester fibers, the cotton fibers and the silk fibers which have the electric conduction capacity are blended and spun after impurity removal to obtain spun yarns, the spun yarns are woven into a gray fabric through a tatting machine, then the gray fabric has low resistivity, and therefore the discharge rate is greatly increased when static electricity is generated and accumulated; meanwhile, the raw materials in a modified antistatic auxiliary agent can react with each other to generate dodecyl polyoxyethylene ether and dodecyl polyoxyethylene ether phosphate, so that the moisture absorption and the conductivity of the antistatic fabricare greatly improved, and a dual antistatic effect is achieved; and boiling-off operation in the preparation process of the antistatic fabric is divided into three stages, so that removal of residualnatural impurities and slurry in the antistatic fabric is facilitated, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to an antistatic fabric. Background technique [0002] Antistatic fabric is a kind of textile fabric after antistatic processing, which is widely used in petroleum industry, mining industry, chemical industry, electronic industry and other industries. In industrial and agricultural production, static electricity plays a very important role, such as electrostatic flocking, electrostatic painting and electrostatic insect removal, etc. At the same time, due to the existence of static electricity, it often brings some hazards, such as fire accidents caused by electrostatic discharge. [0003] In the existing antistatic fabrics, there is a problem of poor antistatic effect, often due to repeated washing friction or long-term exposure to low-humidity acid and alkali environments, which easily lead to the decline of antistatic ability, greatly The normal use of antistatic fabrics is limit...
