Things to note when wearing and storing anti-static clothing
Anti-static clothing is made of special anti-static clean fabrics. It has anti-static and dust-proof properties, is thin and smooth, and has clear texture. It is widely used in electronics, optical instruments, pharmaceuticals, microbial engineering, precision instruments and other industries. The lifespan of anti-static clothing is not only determined by the raw materials and processes, but also whether it is worn and stored appropriately is also a major factor that affects the service life of anti-static clothing. Today, Jingshang Jingmei will share with you the wearing and storage of anti-static clothing. Things to note.
Anti-static clothing is not meant to be worn once and for all. After improper use and repeated washing, its static conductive function may be reduced and cannot meet safety requirements. Therefore, based on nearly ten years of experience in the anti-static industry, Suzhou Chengli has concluded that when wearing anti-static clothing, Precautions when using and storing anti-static clothing:
(1) Different levels of anti-static cloth and anti-static clothing should be selected according to the electrostatic sensitivity of different processing objects in different places.
(2) It is prohibited to attach or wear any metal objects on anti-static clothing.
(3) It is not allowed to put on or take off work clothes at the site where static-sensitive products are operated (changes should be made in the designated locker room). All buttons on work clothes should be buttoned, and the work clothes should be kept as close to undressed as possible.
(4) The anti-static clothing should be washed by a simple method, either machine washing or hand washing. The water temperature should be 30-600°C. The work clothes should be avoided from being washed by strong mechanical and chemical operations. The soaking time should not exceed 3 hours.
(5) Ironing is the same as ordinary cotton fabrics, polyester-cotton fabrics, and the temperature can be above 40℃ and below 85℃. The printed parts cannot be ironed directly with an iron.
(6) Anti-static clothing should all use anti-static fabrics and generally do not use linings. When a lining must be used, the exposure of the lining should not exceed 20% of the entire inner area of the garment.
(7) Several pieces of anti-static clothing purchased in batches should be randomly selected and tested for charge level before wearing. After a certain period of use, especially when the wearer feels an electric shock when taking off his clothes, a retest is required.
(8) When wearing anti-static clothing, it must be worn in conjunction with anti-static shoes specified in GB4385. When wearing anti-static shoes and conductive shoes, insulating thick woolen socks and insulating insoles should not be worn at the same time. The place where anti-static shoes are used should have an anti-static floor, and the place where conductive shoes are used should have a conductive floor. In addition, during the wearing process, the resistance test should generally be performed once every 200 hours or less.
(9) Anti-static clothing must be replaced strictly according to the use cycle of labor protection products to prevent its anti-static function from weakening after repeated washing and failing to meet the requirements. The specific requirements are: each person is equipped with 2 sets of spring and autumn clothes, 2 sets of summer clothes, 1 set of winter clothes, 1 pair of summer shoes, 1 pair of winter shoes, 2 summer hats and 2 autumn hats. The replacement of anti-static clothing and safety shoes is: one set of spring and autumn clothes every two years, one set of summer clothes every year, one set of winter clothes every four years, one pair of summer shoes every year, and two summer hats every two years.
