How to judge the quality of anti static clothing?

It can more deeply protect the use needs of each customer.

First, to understand the qualification of anti-static dust-free clothing manufacturers, but also to make the cost of investment to be better played, because after the test, this will have better quality assurance for the production of anti-static dust-free clothing, so it is recommended that you choose Rongxin anti-static, but also so that the production qualification of the whole manufacturer can be certified, must be tested and produced in accordance with the provisions of national standards, imported production technology and advanced testing equipment, for any unqualified products to be eliminated, In order to protect the rights and interests of customers.

1. Check whether the surface of the anti-static clothing is damaged and color difference, when the anti-static clothing sample is obtained, all parts of it should be inspected to see if there is any detachment, damage, wear, etc., if there are obvious holes, openings, fading, etc., it is not qualified.

2. Customized anti-static clothing, whether the size fits is also very important, and its size should be made in accordance with the standard.

3. The anti-static clothing to be tested is washed first, and then tested, which is mainly to avoid some manufacturers from using ordinary fabrics to soak the clothes with anti-static liquid to make the clothes have anti-static properties.

4. Understand the performance values of anti-static clothing, and use professional instruments for testing

1) Fabric inductive electrostatic tester.

2) Fabric friction electrostatic tester.

3) Drum friction machine.

4) Triboelectric charged charge tester.

5) Fabric surface specific resistance tester.

In terms of data, the range of anti-static overalls is between 10 to 10 ohms to the 11th power of the point, and the amount of charged charge is less than this range or higher than this range. Anti-static workwear manufacturers naturally have to card this standard when producing anti-static workwear, but the quality of the production of anti-static workwear is different, and its service life will be different.

First, quality. The quality of anti-static overalls is also an important factor affecting the life of anti-static overalls, the service life of anti-static overalls is generally higher than that of poor quality anti-static overalls, and the standard for judging the quality of anti-static overalls is the performance stability of anti-static overalls, the tear strength of the fabric, color fastness, shrinkage, etc.

2. Cleaning and sterilization.

Generally speaking, under the correct washing method, the cleaning times of Class A anti-static work clothes are more than 100 times, and the cleaning times of Class B anti-static work clothes are more than 50 times, and the manufacturers will choose to replace the anti-static work clothes if they do not change them, even if they do not replace them, they will be tested more frequently to prevent the failure of the anti-static work clothes.

There are many factors that affect the service life of anti-static workwear, and in order to ensure the performance of anti-static workwear, it is also necessary to test it regularly to prevent the failure of anti-static workwear due to accidents. Qingdao Mei'an Clothing **** is an integrated company specializing in the production and sales of anti-static workwear, with complete production qualifications, perfect production workshops, and independent inspection and testing laboratories, so that customers can be more assured.

Anti-static clothing is used in a specific environment, if you want to extend the life, first of all, you must use it in strict accordance with the use procedures, and secondly, try not to let him use it in a high magnetic and high electrical environment.

Anti-static clothes generally can't be washed, and then if you like to wash often or fight by oil mist soldiers, it will also affect the use of ** clothes.

Affecting the service life of anti-static clothing, I think it may also be in the process of sterilization for a long time, and there is also the use of some very alkaline, corrosive liquid to wash their anti-static clothing.

Hello, I'm glad to answer for you.

At present, the domestic anti-static work clothing market is relatively chaotic, there is a phenomenon of low-price competition, which has brought product quality problems, some manufacturers use various methods, shoddy, fake and real, reduce costs, and achieve the purpose of profit. This is also known as unqualified anti-static workwear. The specific embodiment is as follows:

1.The quality of anti-static workwear exists. This includes substandard quality of conductive fibers and excessively large spacing of conductive fibers on the fabric.

2.There are problems in the design and production of anti-static workwear. For example, some manufacturers use non-conductive electrostatic sewing thread in the sewing of clothes on the cuffs and shoulder armor, resulting in the resistance of the cuffs to the chest surface.

3.There is a problem with the detection of anti-static workwear. In order to reduce costs, some manufacturers put their work clothes on the market without being inspected and tested by the relevant functional departments of anti-static.

Field. In addition, there are loopholes in the internal testing of the enterprise, so there are inferior anti-static dust-free work clothes. In view of the contradiction between the status quo and the requirements, various factors such as fabrics, structures, and processes must be comprehensively considered in the design and production of clothing.

Fabric Factor Fabrics are the basis of the garment, therefore, the choice of anti-static fabrics is especially important for the production of high-quality anti-static workwear clothing. Tianjin strength production of anti-static work clothes are made of high-quality polyester, polyester cotton fabrics, embedded with imported conductive fibers, can be washed more than 100 times, electrostatic properties do not decay.

If you want to judge whether an anti-static clothing is qualified, first check the fabric, which is also the key to determine the anti-static performance! The reason why anti-static clothing can be anti-static is because of the black conductive wire on the clothing, the tighter and more obvious the conductive wire, the better the effect. For some other fabrics, employees will lose their silk and hair after wearing it a few times.

There are quality hazards, and the performance of anti-static clothing made of such fabrics is also poor. At this time, the electrostatic value on the clothes will be high, which will cause dust adsorption, and a large amount of dust will affect the quality of the products. This kind of anti-static clothing encounters professional GMP certification inspection, and 80% of them are unqualified!

The second is the performance index of anti-static clothing:

1.Test with a professional electrostatic tester: the friction voltage of the anti-static suit should be within 200V!

2.After each friction of the anti-static suit, the voltage must drop to within 100V within 3 seconds!

3.The surface resistance of the anti-static suit is 10 6 10 9 !

The anti-static clothing is made of polyester anti-static fabric, which is made by a special process, which has efficient anti-static and dustproof performance.

Most purchases will encounter the same problem, looking for anti-static and dustproof clothing on the shopping platform, and found that ** is in a polarized state, the low ones are only a dozen yuan, and the expensive ones are dozens or even hundreds of yuan, which are also anti-static clothing, why is there such a big difference? This is where the advantages and disadvantages of anti-static clothing lie. So how to solve such a problem?

1. Resistance test: use a surface resistance tester to detect whether its performance is qualified and whether it meets the requirements of the workshop.

2. Test the friction voltage value, after the fabric is rubbed, the voltage will drop to less than 100V within three seconds.

3. The appearance of the fabric should be free of damage, spots, dirt or other defects that affect the performance of the fabric; The style should be simple and functional. The sewing parts are smooth, straight, firm, and suitable for upper and lower tightness, without jumpers, etc.

4. Check the manufacturer's business license and the qualification certificate and test report of related products!

5. You can also inquire about the operating time and scale of the manufacturer. Professional production experience can avoid a lot of after-sales problems, and choosing a strong manufacturer is also conducive to after-sales protection.

Hello, I'm glad to answer for you.

Choose a small resistance value: If the resistance is the same, choose a stable resistance value, and pay attention to distinguish whether the fabric is added with antistatic agents during the subsequent finishing process. The test method is to test the resistance in the warp and weft directions separately through the surface resistance test, if it is the same, it means that there is an antistatic agent, and the measured resistance does not represent the real level.

Check the microstructure: Use a high-powered magnifying glass to check the quality of the cloth surface to compare the size of the gaps between the fibers (which is related to the dust filtration rate), to see if there is any buildup on the fiber surface (related to the amount of dust), and then to see if the fibers are arranged neatly and tightly.

Check conductive fibers: As the core raw materials in anti-static ultra-clean fabrics, checking conductive fibers is specifically to check whether conductive fibers are added to anti-static work clothes in accordance with the specifications or what kind of conductive fibers are added.

For many purchases, buying high-quality anti-static clothing is a headache. The first is that I don't know how to test its anti-static clothing, and the second is that I bought an anti-static clothing and passed the test when I bought it, but after using it for a period of time, I found that its products do not have anti-static functions, and there is no difference from ordinary products.

Take the anti-static overalls as an example, when purchasing, the point-to-point resistance of the measuring device reached the national standard, but after the clothes were washed 3 times, when the point-to-point resistance was measured, it was found that it did not meet the national testing standards for anti-static clothing. The main problem is that when buying this anti-static clothing, the fabric of this anti-static clothing has been impregnated with anti-static agents, so no matter how the point-to-point resistance is tested, it can meet the national standard.

Therefore, when buying products, remind everyone that the quality of the product is the key, don't just look at the cheapness of the product. ** is not the key, the key is whether the quality of the product achieves the effect of preventing static electricity. High-quality products and good service attitude are the first conditions for your purchase.

The range of anti-static clothing is relatively large, which is divided into anti-static clothing and anti-static dust-free clothing.

Anti-static dust-free clothing, this is relatively easy to judge, made of polyester fiber, containing centimeters of conductive filament, but in the normal use of the conductive filament will be worn, so it is best to use an electrostatic resistance tester to measure it. It is best to change this type of uniform once a year (depending on the frequency of use and the environment in which it is used).

As the name suggests, visual inspection is to contact with the hands, investigate with both eyes, and judge the type of fiber according to rich experience. This method of distinguishing conductive fibers is simple and does not require any instruments, but it requires a lot of experience. In addition to this, it is possible to distinguish by removing the yarn from the edge of the fabric.

1. In terms of fabrics, the higher the density of conductive fibers added to the anti-static clothing fabric, the better its anti-static performance.

2. The accessories of anti-static clothing, buttons, zippers, hooks, trips and other accessories should be plastic or nylon as much as possible, and metal materials should not be used.

3. Check whether the reverse side, pockets, welts, and reinforcement fabrics of anti-static overalls are made of anti-static fabrics, don't underestimate these details, they are an important factor in the deterioration of anti-static overalls.

The above points are the issues that everyone must pay attention to when buying anti-static clothing, judge whether an anti-static clothing is of high quality, and let the fabric and details speak!

Hello, I'm glad to answer for you.

The first is the surface resistivity, the resistivity of the surface is the physical quantity that characterizes the conductivity of the surface of the object, and the point-to-point resistance design is also very important, for example, the ratio of the current voltage between the two electrodes on the surface of the material and the DC current flowing between these two points can be applied within a given time. The technical requirements are like this, first of all, the design and performance of the appearance quality requires that there is no damage, no stains, or other defects that affect the anti-static performance of the fabric, etc., which are not allowed.

The second test method is to detect the charged amount of parameters, and the lower the charged charge, the better the protection performance. The relevant guidance of testing parameters is also very important, and the fabric is tested and tested in a timely manner according to the point-to-point resistance method, and the relevant technical parameter table can be referred to. Through continuous testing, you can know whether this anti-static clothing is suitable for you.

Detecting the parameters of the anti-static clothing is an effective way to verify its qualification, not only the new purchase, but also the regular testing of the anti-static clothing in the process of use is the key, we can judge whether the anti-static clothing can continue to be used according to the test results in time, so as not to delay production.
