Button purchasing knowledge
A: Button related 1. Reasonable and correct selection of fasteners According to the characteristics of different fabrics reasonably choose the type of fastener is very important. Due to improper use of fasteners, it is easy to pull the fabric through or pull fasteners off. For example, some knitted fabrics are characterized by their high elasticity, and their weft and weft densities are larger than those of other fabrics. Therefore, attention must be paid when selecting metal fasteners. The shape of riveted parts of fasteners is single-tube, five-claw, or other geometric shapes. In the use of knitted fabrics, it is not easy to use single-tube riveted fasteners. When the fasteners are opened and closed, their opening and closing forces are only concentrated on the riveting points. Due to the reason that the fabrics are broken during riveting, the knitted fabric itself is added. The features are very easy to pull down the fasteners and pull the fabric out. The five-jaw buckle is riveted with five claws evenly distributed on a plane and a circle, and the force distribution state of the claws after opening and closing is evenly distributed. Knitted fabrics and thinner fabrics are suitable for four buckles.
2. Opaque injection molded buttons This type of button is often a button that incorporates pigment directly into a resin to color it and inject it into a variety of colors. When the batch size of the buttons is large and the color has been 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 are polypropylene, ABS, etc. The main advantage of using polypropylene plastic is that this kind of material 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). The mechanical properties are better. 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 coloring buttons is not as good as that of polyethylene, so it is not widely used.
3. Stone buttons 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.
4. Manhattan Button This is a kind of pearl press button that is hot pressed to form high temperature, and it also belongs to the category of imitation bead button. Button types are mainly a single pearl, double pearl, double-colored pearl and so on. The quality of the button's material is good, the price is good, especially its temperature resistance and mechanical strength are much higher than ordinary resin buttons, so it is mainly used for frequently cleaned and easily worn clothes, such as shirt buttons and so on.
5. Free sewing buttons and function buttons The so-called free sewing buttons are buttons that are attached directly to the garment without the seams and are directly attached to some buttons attached to the buttons. The appearance of these types of buttons for a long period of time, variety, and most of them are some combination buttons, mainly for some special occasions, and each button has been filed for a patent, so the use and production volume are limited . Function buttons are a kind of more trendy buttons. In addition to the clothing's connection function, they also incorporate some special functions that have nothing to do with button buttons, such as fragrance buttons, pharmaceutical buttons, Glow buttons, and so on. These types of buttons have all been reported as patents, and their current use is not universal, and their special features are not obvious and long-lasting.
6. Glass pearl button glass Pearl button pearl button features a pearl surface arranged in a corrugated, high pearl brightness, bright spot shine like a cat's eye effect. According to the size of the button specifications, the width of the ripple is also different. The style of various corrugated buttons is very different. Compared with flat pearl buttons, the corrugated pearl button is more beautiful and lively. It is a type of pearl button with a higher grade, and it basically replaces the flat pearl button.
7. Metal hanging buckle Metal hanging buckle, generally used as a denim clothing series, jacket series, bib pants series of clothing accessories, styles varied, there are separate use in the clothing, such as adjustment buckle, D buckle, pull heart buckle and so on. It is also used with other accessories. For example, in the denim series, the I-shaped buckle and the hoist buckle are used together. Metal hanging buckles are made of iron, copper and alloy. Processing forms include bending, stamping, and die casting. Its shape and size are designed and developed by each manufacturer. The name of the hang buckle has no uniform requirement for each factory. It is generally named according to the similar shape and function of the hang buckle. Such as various sizes of abalone deduction, square pull heart deduction, Japanese deduction, three-way deduction, D-buckle, hyacinth deduction, elastic band buckle, clip buckle, etc., are named after such methods.
