When it comes to customizing professional wear, many people will not be unfamiliar with it. For different occupations, it is necessary to choose clothes according to the particularity of their own occupations. For example, occupations in the workshop must have neat, dirt-resistant and anti-radiation-proof materials. So today we will take a look at what factors should be taken into consideration when selecting professional wear for different occupations.
Workers engaged in chemical production or laboratory workers shall wear rubber aprons, rubber long-barrel gloves, and rubber long-sleeve overshoes in addition to solid, tight-sleeved factory clothing when working in workshops or laboratories containing corrosive substances. If necessary, rubber work clothes with a helmet that can be blocked from the outside should be worn.
For agricultural production workers who perform their usual field work, the usual light-colored rags or khaki clothing can be used. Foresters wear three tight factory uniforms, tightening their collars, cuffs, and ankles to prevent pests from invading.
Reasonable wear and clothing can help regulate body temperature and maintain skin, so as to achieve the purpose of waterproofing, fire prevention, heat radiation protection, antivirus, and animal bite prevention. Wear and factory service is not reasonable, and it is directly related to human well-being.
When working in a high temperature environment, the amount of heat radiation on the touch is large. Therefore, the clothing worn when working under high temperature conditions should be as white or light as possible, and the fabric should be thick and soft. In addition, sweating is high at high temperatures. Some people like upper body and shirtlessness. This causes thermal radiation to burn the skin, leaving the skin hot and dry, and degrading its cooling function. It also simply hurts the body. Therefore, working under high temperatures may not only wear clothes, but also should wear thick long-sleeved clothes and trousers, and wear gloves to face masks, foot guards and so on.
Mechanical workers often travel between machines, demanding that the clothes be prevented from being twisted by the machine, and that collision resistance be required. Therefore, the requirements of the factory service are tight, and the hem, cuffs, and trouser legs can all be buckled. Moreover, the demand for the fabric is more robust, wear-resistant, and the color is preferably deeper.
In addition to selecting clothes to be worn in accordance with the nature of the job, they should also pay attention to special clothes. The clothes should only be used in the workplace. Do not take them home to prevent the spread of pathogens or poisons. Should also pay attention to keep clean, regular, and often clean, patchwork, to ensure that the factory clothes play a due maintenance effect.

3. Application
Printing and dyeing industry: mainly used for dyeing vat dyes suspension, leuco acid staining, dispersion and soluble vat dyes dyeing. Also be used for silk / wool interwoven fabric dyeing, the yarn is no color. Mainly used for industrial dye dispersion and diffusion of color lakes manufacturing additives.
Building materials industry: as early strength cement water reducing agent, the amount of 0.5-1% by cement after the shock has good dispersion effect, increasing the strength of cement. Diffused N of concrete tensile strength, impermeability, frost and compressive modulus of elasticity are improved, no corrosion of steel effect.
Pesticide industry: It can be widely used in wettable pesticides, with good dispersion and solubilization, can significantly improve the efficacy, dosage according to product requirements. Example: buprofezin, the amount of 3-5 %; thiophanate amount of 0.8-1.5 %, 0.8-1 % Kai Ling vegetables.
Electroplating industry: the color is added, crossing pigment dispersants N allows uniform dispersion can significantly improve the plating surface brightness, and the amount is usually 10% of the pigment.
Rubber industry: rubber (latex) of industrial production process, the dispersed substances such as sulfur accelerator, antioxidant zinc oxide fillers ( such as barium sulfate , calcium carbonate ), etc., added to the dry weight of a Dispersing Agent N2-4% , 10% Dispersant solution prepared in advance , and along with the other components in a ball mill grinding , can improve the dispersion effect and shorten the milling time .
Packing: 25kg bags.
Storage: two years and must be upload and download lightly.
