For example, gold-plated buttons are currently popular on the market, and the price is relatively low. Such buttons are usually made of ABS plastic after gold-plated electroplating. In the initial stage of button-making, its color is more beautiful, but if the buttons Surface treatment is not strict, storage time is slightly longer, it will fade to green, completely changed into another look.
If this kind of button is used on a high-end garment, the garment will not be sold and the buttons will change color, which will inevitably affect the sales of the garment. So when choosing the button, in addition to the beauty of color and shape, we must also consider how the durability of the color (if the plating button, the quality of the plated 16K gold is better). In addition, the eyelet strength of the button must be large.
If dark-eye buttons or buttons with handles, the wall thickness at the eye socket should be sufficient. These types of buttons often use resin buttons as the main body, and are appropriately decorated with various metal or ABS gold-plated inserts and coated with transparent resin epoxy adhesive. They are both stable, beautiful, and durable.
However, today's buttons seem to be more environmentally friendly and the choice of materials is particularly important. As we all know, lead and nickel are heavy metals that are very harmful to the human body. In recent days, Ningbo Textile Inspection Center of the Inspection and Quarantine Bureau conducted a total lead test on a number of accessories, such as buttons and zippers, that were exported to European garments. It was determined that the total lead content in the resin buttons of the batch was as high as 3200 mg/kg, and the total lead content of the fastener element of the dark green resin zipper was 370 mg/kg, far exceeding the 90 mg in the OEKO-TEX Standard 100 standard. The limit requirement for /kg is an unqualified product.
One is the lead salt stabilizer often used in plastics production. Lead salt stabilizers are widely used in the production of opaque plastic products due to their excellent thermal stability, excellent electrical properties, and low cost. The second is lead-containing dyes, pigments, and auxiliaries used in the plastic coloring process.
Recently, accessories such as zippers, buttons, belts, and metal fasteners have been increasingly emphasized in the design of garments. In particular, some accessories with a sense of design have been widely used to embellish popular fashion ladies' and casual wear to enhance garments. The grade and value. However, for the apparel industry, the issue of textile export quotas is no longer the main contradiction in today's textile and clothing industry. Instead, environmental indicators of product quality are used as new export restrictions for green trade barriers. In addition, the environmental protection of clothing can not be separated from the environmental protection of raw materials, accessories in addition to practical and decorative features, but also should ensure health, safety and environmental protection.
