Buttons are one of the details of clothing, but also because of this small details before the return. In recent years, China has paid more and more attention to the concept of protecting the ecological environment. Various advertising campaigns are a theme of "environmental protection." Nowadays, there are many environmentally friendly products around our lives. This also shows that the awareness of environmental protection has become more and more popular.
Button environmental protection requirements: The environmental protection of metal buttons mainly refers to the requirement for flawless plating, surface treatment such as oil injection, and the absence of flaws. For environmental protection buttons, electroplating must be based on non-barium electroplating, and according to the requirements of garment production and processing, it is sometimes necessary to further process after electroplating: such as trusses, anti-acid trusses, high temperature trusses, etc., these are not much with environmental protection Relationships only play a role in protection (for example, preventing discoloration, preventing rust, etc.). According to customer requirements, we may also spray, grease, dip, and insert diamonds on the surface of the electroplated buttons. Remember that the materials used in these processes must be made of environmentally friendly materials. The current method of detecting environmental protection buttons is through drug testing (similar to the method of pH test paper, using Amoniya potions for testing), and QCs of general production plants can perform tests on their behalf. Common buttons in the rolling color, green bronze, white zinc, red bronze and other colors are environmentally friendly colors. Some garment factories require manufacturers to send products to testing agencies for testing and issue inspection certificates. Such as SGS test report. Needle detector requirements: The needle detector refers to the use of electromagnetic principles, the product of the unit area of ​​iron (nickel) detection. If electroplating is not flawless, the needle must not be crossed. High-precision copper products, nickel-free surface treatment, can check the needle. Because the copper material in the classification, there are 62/65/68 (68 copper on the market, actually 65 high-grade copper), and sometimes even the manufacturer uses some copper material for waste recycling, which contains high iron content. It is not possible to pass the needle.
In summary, the button product requirements for environmental protection means that the finished product does not contain azo, lead-free or nickel-free products. After the needle is detected, the product can pass the needle detector. The prevailing view is that environmentally friendly products may not be able to pass the inspection needles, but products that pass the inspection pins must be environmentally friendly. Of course, as an environmentally friendly metal button, the material itself must not be ignored. If we use buttons containing excessive amounts of iron to make buttons, the material will not be able to be electroplated without flaws, so it is impossible to make environmentally friendly metal buttons.
