Button Knowledge

One

It is important to choose the type of fastener according to the characteristics of different fabrics.

Because of the improper selection of fasteners, it is easy to pull the fabric out or fasten it off. For example, some knitted fabrics have large elasticity, and the density of warp and weft is larger than that of other fabrics. When selecting metal fasteners, we must pay attention to the shape of fastener riveting, with single tube, five claws or other geometric shapes.

When knitted fabric is used, it is not easy to choose the fastener with single tube shape riveting. When the fastener is opened and closed, its opening force only concentrates on the riveting point, and because of the breakdown of the fabric and the characteristics of the knitted fabric itself, it is easy to puncture the fastener and pull the surface material out.

The five RIPs are evenly distributed on a plane and circumference, and the stress state after opening and closing is evenly distributed.

Knitted fabrics and thinner fabrics are suitable for four buckles.

2. opaque injection molding

Such buttons are often painted directly into the resin coloring and injection into various colors of buttons.

When the number of buttons is large and the color has been determined before production, the method of pre mixed pigments is often used.

The advantage of this method is that relatively inexpensive plastic can be selected to reduce cost and facilitate injection molding.

Commonly used plastics for coloring plastic buttons are polypropylene, ABS and so on.

The main advantages of polypropylene plastics are low price, low requirement for mold, good injection molding technology, excellent corrosion resistance of injection products, and excellent mechanical properties of buttons.

In addition to polypropylene, ABS is also used to produce colored plastic buttons, but the price of ABS is higher than that of polypropylene, and its resistance to organic solvents is worse than polypropylene.

Generally speaking, the comprehensive performance of ABS colored buttons is not as good as that of polyethylene, so it is not widely used.

Three

At present, the popular stone buttons in the market are mainly marble buttons.

The production of marble buttons has been produced in batches.

Marble buttons are characterized by extremely high hardness and wear resistance. They are resistant to high temperature and organic solvents and are not corrosive to ordinary acids and bases.

From the appearance of buttons, they are very distinctive because they are decorated with various natural patterns. They can be used for special occasions and are loved by some people.

4. Manhattan buttons

This is a hot pressing, high temperature resistant pearl button, and also belongs to the category of imitation button buttons.

Button types are mainly single pearlescent, double-layer pearlescent, two-layer multicolored pearlescent and so on.

The quality of the buttons is good and the price is good. Especially its temperature and mechanical strength are much higher than that of ordinary resin buckles, so it is mainly used for clothes that are often washed and wear easily, such as shirt buttons.

5. seamless buttons and functional buttons.

The so-called seamless button is a button that is connected directly to the garment without any thread stitching.

This kind of button appears for a long time and has many varieties, and most of them are some combination buttons, which are mainly used for some special occasions, and each button has been reported patent, so the usage and production batch have been restricted.

Functional buttons are a new type of buttons. Apart from having the linking function of clothing, they have some special functions, such as scent buttons, medicament buttons, luminous buttons, and so on.

All these buttons have been reported patent. The current use is not universal, and its special functions are not obvious and lasting.

6. glass pearlescent buttons

Glass pearlescent buttons are characterized by a wavy shape of pearlescent on the surface of buttons, bright pearlescent and bright spots that shine like cat eyes.

The width of the corrugation varies according to the size of the buttons.

The styles of all kinds of corrugated buttons are very different. Compared with the flat pearl buttons, the corrugated pearl buttons are more beautiful and lively. They are a kind of pearlescent buttons with high grade. They basically replace the plane pearlescent buttons.

7. metal fastener

Metal hanging buckles are usually used as accessories for denim clothing series, jacket series, and shoulder strap trousers. They are of various styles and are used individually in clothing, such as adjusting buttons, D buckles and pulling buttons.

It is also used in conjunction with other accessories.

For example, in the cowboy series, the buckles are matched with the gourd buttons.

Metal hanging buckle selection material has iron, copper, alloy three kinds.

There are three main types of processing: bending, stamping and die casting.

Its shape and size are designed and formulated by various manufacturers themselves.

The name of the factory is not uniform. It is usually named according to the similar shape and function.

For example, all kinds of abalone buckles, square buckle buttons, day buckles, three line buckles, D buckles, gourd buttons, loose belt buckle buttons, belt buckles and so on are all named according to this method.
