Purchase anti-static overalls to note several issues which

With the changing times, people's aesthetic has undergone enormous changes, has been greatly improved. For example: the same skirt, the traditional skirt suit has no one likes to wear, step skirt, Side skirts, front opening skirt style dresses began to be pretty ladies of all ages. In the uniform design process, if banks can make comprehensive use of the logo and colors which will play a finishing touch.
The choice of fabrics is very important, not all good fabrics are suitable for uniforms. Select fabrics must consider regional, such institutions in the South, should use moisture-proof, easy to dry, breathable fabric, while in the north should be more consideration insulation, anti-wrinkle, anti-static fabric better efficacy . Best not to use wool and pure silk fabrics. If you use cotton fabric, also be sure to select through the iron-treated, otherwise the staff will bring a lot of trouble.
Therefore, enterprises in the procurement of antistatic fabric clothing, do not just from the price to consider, from the psychological needs of employees, the actual function, and so comprehensive selection! After all, the clothes are not solely for the purpose of a function, where wearing comfort is also particularly important.

Precautions for fire-retardant protective clothing

Cupro Common Tiger kapok, near the flame that is burning, burning speed, yellow flame, emitting ester sour, very few ashes after burning, only a small amount of gray and black ash.

Fabric classification

Soft fabrics are generally more thin, good drape, shape lines smooth, natural stretch clothing outline. Soft fabrics including evacuation of fabric structure of knitted fabrics and silk fabrics and soft thin linen fabrics. Soft knit fabric often used in fashion design linear concise style reflects graceful curve of the body; silk, linen and other fabrics are more common and there are loose pleated effect of modeling, performance fabrics sense of flow lines.

Very cool fabrics have clear lines sense of volume, can form the fullness of clothing outline. Common with cotton, polyester cotton fabrics, corduroy, linen and a variety of thick wool and synthetic fabrics, such fabrics can be used to highlight the design of costumes accuracy of such suits, suit design.

Surface smooth and shiny fabrics that reflects the light, there is a sense of shine. Such fabrics include satin fabric structure. Evening dress or most commonly used in theatrical performances served to produce a strong dazzling visual effects. Shiny fabrics dress performances in a wide degree of freedom in shape, may have a simple design or a more exaggerated modeling approach.

Tinggua thick heavy fabrics, can produce a stable shape effects, including various types of thick woolen cloth and quilted fabrics. The fabric has a physical sense of expansion, not too much use of pleating and accumulation, the design of A-and H-shape most appropriate.

Transparent type fabric texture thin and transparent, with elegant and mysterious artistic effect. Including cotton, silk, chemical fiber fabrics, such as georgette, satin silk, chemical fiber, lace and so on. In order to express the transparency of fabric, commonly used natural lines plump and full of change and a round table H-type design modeling.

Functional fabrics are fabrics with special functions, such as fire-retardant, antistatic fabric, anti-acid and so on.

Special protective equipment commonly used in life

1, seat belt use period

    Seatbelt use two years later, the situation should be sampling bulk purchaser once. If qualified, the batch can continue to use seat belts. For pumping tried transect, safety rope must be replaced before further use. Frequently used rope, should always do visual inspection, abnormal, should be immediately replaced with a new rope. The use of a string of 3 to 5 years.

     2, antistatic fabric and anti-static overalls shoes Precautions

     (1) GB 12014-89 "anti-static overalls" provides that: wear anti-static clothing must be specified with the GB 4385 matching wearing anti-static shoes.

     (2) due to multiple washing, anti-static overalls antistatic properties will be reduced, so that the ambient temperature is high, labor-intensive, the number of frequent washing of enterprises to develop an appropriate period of use should be shorter.

     (3) anti-static shoes wearing course, generally not more than 200 hours resistance test should be carried out once, such as failure, can not continue to use.

     3, the electrical insulation shoes, period of use insulated gloves Precautions

     Electrically insulating footwear include: electrical insulation shoes, canvas shoes, rubber surface shoes, plastic shoes four categories. According to the labor intensity of each unit, operating in different environments, develop a reasonable period of use. But note here the following: First, storage, from the factory more than 18 months, shall be carried out only by the electrical properties of preventive inspection; second is where the end to help the Department of corrosion damage, can no longer be electrically insulated shoes wear; three is to use at least every six months once electrical performance tests, such as failure can not continue to use. Insulated gloves period of use, the units can be made according to how frequently required, but must be requested prior to each use self-blowing, at least once every six months electrical performance tests, such as failure can not continue to use.

     4, with hearing protectors Precautions

     Hearing protectors including anti-noise earplugs, earmuffs anti-noise, anti-noise helmet. In general, anti-noise, anti-noise helmets best, not only noise deadening air conduction, bone conduction can reduce noise on the ear injury, should be used in high noise environments, earmuffs, followed by anti-noise performance, and the worst anti-noise earplugs in 1000 ~ 2000Hz band generally sound attenuation value of only 10 ~ 20dB.

Use of personal protective equipment there are several errors

Myth # 1: Wear personal protective equipment can not wear

        Experts point out that personal protective suits to eliminate or reduce occupational hazards for workers health effects, "Occupational Disease Prevention Law" stipulates that the employer must provide laborers to meet the requirements of protective equipment, while the obligation of workers to wear protective equipment.

        Myth # 2: Workshop does not smell, you can not wear personal protective equipment

        Experts point out that many of the harmful gas is a colorless, odorless, tasteless, does not have any warning, do not feel. Even flavored, the perception of sensory organs on the outside have their limitations and individual differences. Therefore, over-confident feeling, may cause occupational poisoning.

        Myth # 3: gauze masks can be used to dust

        Not be used as ordinary gauze masks dust masks. We now use the gauze masks, although cheap, summer sweat, warm in winter, but this masks (even 16 thickness) can easily lead to pneumoconiosis protection respirable dust hazards, dust requires special dust masks.

        Myth # 4: Medical masks used antivirus

        Medical masks to prevent disease spread by droplets, but can not filter out toxic gases. For different poisons, you need to use a different filter effects of protective masks. Generally volatile organic gas can with activated carbon respirator.

         Myth 5: dust masks washed reuse

         Dust mask filter is not washable. Dust masks are used efficiently filter is usually woven material, and some also rely on fiber filters with electrostatic charge respirable dust. After washing the filter microstructure will be damaged, appear invisible cracks, holes, will be significant loss of electrostatic charge, the filter performance in serious decline.

         Protective equipment belonging to a passive protective measures, in any case should be the first to take the advanced production technology, good engineering protection facilities to proactively prevent occupational diseases; in protective facilities are not able to completely eliminate occupational hazards in the case before considering the their workers with appropriate personal protective equipment. Notably, personal protective equipment is not a panacea, and any personal protective equipment has its applicability, limitations, need to consider the use of the environment and the scope of protective equipment.

Large inventory of special protective fabrics

Special protective fabrics, including anti-static fabric, fabric anti-acid, anti-oil-water repellent fabric, waterproof fabric, x-ray protective fabrics, high-voltage electrostatic protective fabrics. The application of such fabrics produced according to specific work clothing needs to be selected and the needs of the environment with.

Antistatic fabric is to prevent accumulation of static anti-static clothing fabrics. Anti-static clean fabric with special polyester filament yarn, warp or weft woven conductive fibers embedded. An efficient, permanent anti-static, dust-proof performance, thin slip, textured clear characteristics. In the production process according to the level of garments require different styles, and the use of conductive fibers sewing the garment parts to maintain electrical continuity; sleeves and pants for the unique two-tier structure, the inner conductive or antistatic rib, to meet the high-level dust-free environment. This fabric is made of stainless steel fibers, sub-conductive fibers, antistatic fibers and cotton blended or mixed fabric, corona discharge or leakage can be automatically discharged, to eliminate static electricity j clothing and body, in addition to clothing, can be used to produce anti- Electrostatic hats, socks, shoes, and so on.

Acid resistant fabric or fabric with acid-resistant rubber, plastic and other materials suitable for persons engaged in contact with the acid used. Acid resistant material based on the nature of the material, divided into breathable and air-tight. Breathable fabric used in anti-acid, mild acid contaminated sites protection, spare clothing products can be divided into two kinds of style and gown; air-tight acid-proof fabric for severe acid contaminated sites, can be made of one-piece, spare style, apron-style and other apparel. Acid and other acid-proof fabric performance should meet the relevant industry regulations.

Welding protective fabric is based on fabric, leather or made through the foil or spray fabric lining. The oil resistant and water-resistant fabric is collated, that the fabric is treated with a fluoropolymer coating and finishing padding fabric with craft, the fiber surface energy exclusion, alienation oil and water-based liquid medium, thus to avoid hindering breathable and comfortable, but also Such liquids can effectively resist the erosion of underwear and body, can be divided into the winter season, summer, oil resistant and waterproof fabric.

Mention waterproof material, in fact, only then l5 century Indian rubber tree out of the slurry coated cloth, tarpaulin manufacturers in Europe from 1735 began. But some of the more advanced industrial countries, due to the progress of science, improvement of living standards, industry, agriculture, the development of transport, especially munitions consumption increased year by year, requiring a large number of functional coated fabrics, coated fabrics because profit higher than the general textile production process, so in some foreign industrialized countries attach great importance to this work, it developed quickly. On the development of waterproof material, waterproof clothing research, quality inspection and the necessary equipment, equipment, research, etc., are in a leading position.

Rubber waterproof clothing is the main material, the use should not touch a variety of oils. Rubber is a value extracting rubber, latex rubber, grass and other plants after processing made of a flexible, insulating, and air impermeable material. High elastic polymers. Into natural rubber and synthetic rubber of two kinds. Natural rubber from the rubber tree, grass and other plants to extract rubber gum after processing is made; synthetic rubber from various monomers by polymerization reaction. Rubber products are widely used in industrial or all aspects of life.

Antistatic Fabric Description

Fall color anomalies boring day, much friendship will bumped hair, clothes from electrostatic disgrace accidents, thus taking advantage of anti-static fabric apparel born. Here are a few antistatic fabric and its practical range.

Conductive silk.
