What kind of fabric is anti-static fabric?
Anti-static fabrics are functional fabrics that can prevent static electricity hazards. Anti-static fabrics are woven into fabrics by evenly mixing conductive fibers into them. Conductive fiber refers to the general term for fibers made entirely or partially of conductive or sub-conductive materials using metal or organic materials. Its volume resistivity PV is between 104-109 ohms. Most protective clothing made of anti-static fabrics is made of special polyester filament/elastic yarn, with conductive fibers embedded in the warp or weft direction, and is woven through a special process. Compared with protective clothing made of traditional anti-static agents, this kind of fabric not only has good dust-proof performance, but also has anti-static effect enhanced several times. The conductive thread will not break. Due to its good dust-proof performance, it greatly reduces the number of washes. It is the fabric of choice for most anti-static protective clothing.
The nature and discharge mechanism of anti-static work clothes
Anti-static work clothes made by adding conductive fibers to chemical fiber fabrics do not produce dust or flakes, and are not easy to carry fine dust. The unique design also prevents the intrusion of dust. It is not easy to carry fine dust, and the unique design also prevents the intrusion of dust. Its electricity dissipation is based on two mechanisms: charge leakage and neutralization. When grounded, the static electricity on the fabric is not only neutralized by the corona discharge of the conductive fibers, but also discharged to the earth through the conductive fibers; when not grounded, the static electricity on the fabric is eliminated by the weak corona discharge of the conductive fibers. Practice has proven that anti-static work clothes can effectively suppress static electricity in clothing and eliminate or reduce the harm of electrostatic discharge.
Use of anti-static clothing
Wash cycle: once a week
Service life: under normal use and professional washing, more than 50 times of washing
Note:
1. Avoid sharp metal edges from scratching fabrics and causing damage to clothing fabrics.
2. In order to reduce the dust-generating and dust-shielding properties of the fabric, our company uses chain stitch sewing to prevent sharp objects from hooking the sutures during use and cleaning, so as to avoid needle stripping and affecting use.
3. When performing dust-free cleaning, zippered clothing should be zipped up to reduce entanglement and avoid abnormal damage to the zipper.
4. When cleaning, use special protective tape for hook and loop fasteners to adhere properly to avoid entanglement or mechanical damage to the clothing fabrics.
5. Avoid using a brush to avoid damaging the fabric.
How to clean anti-static fabrics
In the process of industrial production (such as optoelectronics, semiconductors, precision processing, injection molding, pharmaceuticals, etc.), there are many potential sources of pollution in clean rooms. Among them, the biggest threat is also easily controlled, that is, human pollution factors. People will produce pollution during clean room activities. A large number of dust particles, including: 1. Active dust particles: such as bacteria and yeast; 2. Inactive dust particles: such as hair, dander, etc.; 3. Chemical substances: such as sodium, potassium, magnesium, etc. The most effective method at present is to take away dust particles through isolation and cleaning of clean room work clothes, so that pollutants are not spread into the clean room environment, so as to reduce the pollution of the clean room environment by personnel. The management of dust-free clothing systems plays an important role in pollution control in clean rooms. Under normal circumstances, clean anti-static work clothes are washed once a week. Some demanding environments require cleaning once a day, and you even need to change into clean dust-free clothes every time you enter the clean room. Although the fiber itself is a clean fiber that is difficult to stain, how to maintain it is an important factor, and that is the cleaning method. Of course, if you use ordinary washing methods, it will get stained. So special methods must be used. Clean work clothes, from a management perspective, must also be cleaned and packaged in a clean room during cleaning. As an important means of pollution control, the cleanliness requirements of clean clothes are very high.
The following are very important points when cleaning:
1. Before washing, check for scratches, damage, buckles and other accessories. Defective items must be repaired, replaced or scrapped.
2. Washing, drying, and packaging must be done in a clean room that is cleaner than the clean room where work clothes are used.
3. The cleaning temperature should not exceed 40 degrees, and the drying temperature should not exceed 60 degrees
4. When rinsing and water-permeating, antistatic agents can be used to improve antistatic properties, but the antistatic agent selected should be well combined with the fibers and no dust will fall off.
5. Work clothes with buckles should be washed in the buckled state.
