Description
Technical Field
The invention belongs to the field of textiles, and particularly relates to a manufacturing method of an anti-static high-temperature-resistant fabric.
Background
Static electricity, which is a static or non-flowing charge, is formed when the charge accumulates on an object or surface. For example, in winter in the north, people are easy to be charged with static electricity, and when people contact with other people or metal conductors, the phenomenon of discharge can occur. People can feel the acupuncture feeling of electric shock, and sparks can be seen at night, which is the reason that chemical fiber clothes and human bodies rub to bring positive static electricity to the human bodies. The persistent static electricity can cause the pH value of blood of a human body to be increased, the excretion amount of calcium in urine to be increased, the blood calcium to be reduced, and the adverse effects on the heart, the brain and the skin are caused.
Meanwhile, the industrial harm of static electricity is more serious:
(1) causing malfunction or malfunction of the electronic device and causing electromagnetic interference.
(2) Breakdown of integrated circuits and precision electronic components, or aging of components, lowering production yield.
(3) High-voltage electrostatic discharge causes electric shock, and personal safety is endangered.
(4) Explosion and fire are easily caused in production places of various flammable and explosive articles or dust and oil mist.
(5) Electronic industry: dust is adsorbed to cause pollution of integrated circuits and semiconductor elements, and the yield is greatly reduced.
(6) Film and plastics industries: the film or the film is rolled unevenly; the film and the CD plastic disc are stained with dust, which affects the quality.
(7) Paper making and printing industry: the paper is not rolled up neatly, the overprinting is inaccurate, the dirt absorption is serious, and even the paper is bonded, which affects the production.
(8) Textile industry: causing the damages of root filament fluttering, twisting and breaking, yarn entanglement and the like.
Especially in flammable and explosive working environment, and when processing and using places of electronic components work, the requirement on static electricity is extremely severe. At present, static electricity generated and carried by a human body is mainly controlled by antistatic clothes. However, the antistatic clothing in the present stage has a single function, and cannot meet the requirements of complex and severe working environments, such as high-temperature environments. In addition, the fabric is stiff and heavy, and the wearing comfort is poor.
