About polyester button

Synthetic materials (resin) buttons are the most widely sold, most versatile, and most popular type in the world button market. They are the product of modern chemical industry development. Resin buttons, like other resin products, are colored before molding. The disadvantage is that the color is not bright, mostly black, white, gray, beige and other light colors, button color and clothing are often inappropriate, affecting the beauty of clothing. In addition, since the buttons are indeed small in the huge family of clothing, under the control of that big industry and big products, it seems that there has never been too much enthusiasm for a small addition to buttons. For a long time, people's understanding of buttons has always determined its value at its price. This traditional concept has hampered the development of small buttons. As a result, the majority of domestic button enterprises still remain in small-scale workshop-style production methods. This has widened the distance from the fast-growing garment industry, making the buttons industrial There are misunderstandings in positioning and ideas.

 Unsaturated polyester resin is an important variety of synthetic resin, and its development is extremely fast. Because unsaturated polyester resin has excellent mechanical properties, electrical properties, and chemical corrosion resistance, coupled with the availability of raw materials, processing technology is simple and practical. Its value is high, and its production and processing industries are developing very rapidly. Its products have been widely used in various fields of the national economy, such as construction engineering, electrical engineering, transportation, aerospace, chemical industry, daily-use products, and arts and crafts.

In foreign countries, such as the United States, Britain, Japan, and Italy, polyester resins are injected into lead molds for hot-casting. Unsaturated polyesters have high hardness after curing and they are very light in color and easy to color. This process can be used. Produce a variety of knife handles, brush handles, umbrella handles, buttons and other daily products. The development of the modern Chinese button industry should be said to start from the Suzhou Jiamei Button Factory. In May 1985, the plant introduced the internationally advanced Italian unsaturated polyester resin button production line from the 1980s and was first developed in China. The new button products have become China's first manufacturer of unsaturated polyester buttons, thereby promoting the development of the domestic button industry and shortening the distance with the international advanced level. In foreign countries, in 1957, the production of "pearl buttons" using unsaturated polyester castings began. However, this technique was only introduced in China in 1985. After a lag of 27 years, in general, China's unsaturated polyester resin production technology lags far behind the world's advanced level. For unsaturated polyester resins, there are only a few hundred kinds of products, and thousands of foreign products. Most of them are generic resins, and many important special varieties are lacking. For the button industry, the gap is even greater. Today's button, after deducting its original linking function, embodies its decorative and beautifying functions. Its decorative function far exceeds its practical function. Buttons now play a "finishing touch" on clothing. It is already an art ornament. In the bustling fashion market, there are often many colorful buttons such as gold, diamonds and diamonds, which add rich colors to people's lives. They are deeply loved by consumers 。
