Buttons are the clothes that humans often escort. Its use has been more than 6,000 years old. As early as 4000 AD, the Persians of Iran’s ancestors had already made buttons with stones. China’s Zhou Dynasty has begun to adopt the blouse under the blouse. Both men and women wear two pieces of clothes under the upper skirts. There are officials who specialize in making dresses. When the officials of the civil and military officials perform the ceremony, they must wear dresses. At that time, the use of clothing was more standardized and the clothing system was quite complete.
The following introduces you to three kinds of special buttons. The application range of these three buttons is not wide, but it is very special, and only some special occasions are used.
Opaque plastic injection buttons These buttons are often pigmented directly into the resin and molded into a variety of color buttons. When the volume of the button is large and the color is determined before production, the method of premixing the coloring of the pigment is often used. The advantage of using this method is that relatively inexpensive plastics can be selected to reduce costs and facilitate injection molding. Commonly used plastics for pigmented plastic buttons include polypropylene and ABS. The main advantage of using polypropylene plastic is that it is low in price, low in mold requirements, good in injection molding technology, and excellent in corrosion resistance of injection molded products (almost resistant to most organic solvents and acid and alkali corrosion). Good mechanical properties. In addition to polypropylene, ABS is also often used to produce colored plastic buttons, but ABS is more expensive than polypropylene and inferior in organic solvent resistance than polypropylene. In general, the overall performance of ABS color buttons is not as good as that of polyethylene, so it is not widely used.
Stone Buttons The popular stone buttons currently on the market are mainly marble buttons. The production of marble buttons has been mass produced mechanically. Marble buttons are characterized by extremely high hardness and wear resistance; they are also resistant to high temperatures and organic solvents and do not corrode with normal concentrations of acids and bases. From the appearance of the button, because of the various natural patterns embellished, but also very unique, can be used for special occasions, for some people love.
Manhattan Button This is a type of pearlescent button that is thermoformed to form a high temperature. It also belongs to the category of imitation beryllium button. Button types are mainly single pearl, double pearl, double-colored pearl and so on. The quality of the button material is good, the price is good, especially its temperature resistance and mechanical strength are much higher than the ordinary resin deduction, so it is mainly used for frequently cleaned and easily worn clothes, such as shirt buttons.
