The Classification Development Of Buttons

A button is a knot on a piece of clothing that connects the two sides of the front. Originally used to connect the front of a garment, it has gradually developed into something more artistic and decorative in addition to maintaining its original function, that is, personalized. A good button it can make your clothing more perfect, play the role of “finishing touch”, and play a certain aesthetic role. Especially women’s clothing appeared with a lot of colorful decorative buttons. In detail: the button connecting the front of the clothes, that is, we often say that the button is not connected, such as the belt connection buckle, but we are used to the two as one, collectively known as the button.

Button classification

a, according to the button size (i.e., diameter)
That’s 14#, 16#, 18#, 20#, 60# and so on! Its change of label formula is diameter = model size *0.635(mm). If we have a button in our hands and don’t know its size, we can measure its diameter in millimeters with a caliper and divide by 0.635.

B. There is another way to express the size of the button, namely L
The conversion relationship is as follows:

Button size:
LIGNES 1L=0.635MM 1MM=1/25 INCH INCH) Unit :L, lignes
14L= 8.89MM =11/32″
16L=10.16MM =13/32″
18L= 11.43MM =15/32″
20L= 12.7MM =1/2″
60L= 38.1MM =1-1/2″

C. Number and unit of buttons:

Play OZEN D.=12PCS
Rogers’s G.=144PCS
GREAT GROSS GG.=1728PCS=12G. Great gross gg.= 1728pcs = 12g

D. By material:

Natural types: real shell buckle, coconut buckle, wood buckle, bone buckle (common horn buckle), bamboo buckle, fruit buckle, shell buckle, and so on
Chemical: organic buckle, resin buckle, ceramic (zirconia) buckle, plastic buckle, composite buckle, urea buckle, spray paint buckle, electroplating buckle, child buckle, cloth buckle, chin buckle, etc
Others: Chinese knot, four-fold buckle, metal buckle, horn buckle, imitation leather buckle, I-buckle, cowboy buckle, magnet buckle, laser letter buckle, vibrating buckle, etc

e. In the resin buckle, it can be divided from the blank:

Rod buckle: pearl buckle, pattern buckle, ordinary rod, and so on
Plate buckle: pearlescent corrugated plate (including false corrugated, true corrugated), pearlescent plate, stripe plate, monochrome plate
Manhattan: Colorful buttons, monochrome buttons

F. From the hole:

Dark eye button: usually on the back of the button, through the button radial perforation.
Bright eye button: directly through the front and back of the button, generally have four eye buttons and two eye button
High foot button: On the back of the button, but on the back of the button there is a handle with a hole in the handle.

G, from the safety deduction method points:

Hand stitch: sewn directly onto a garment with thread;
Four-button: the mold is used to buckle on the clothes;

H, from the luminosity:

There are light buckle, half light buckle, no light buckle, matte buckle
The manufacturing process of buttons
Unsaturated resin + curing agent promoter | + + paste mix – processing – “bar” bar workshop – “choose sheet billet workshop –” buckle workshop process – “the slab special fastener workshop, polishing workshop The finished product workshop
A. Production process of bar material:
B. Production process of sheet material:
C. Function and standard of blank selection:
Exclude nonconforming products before the next process
① Blank thickness according to the company’s requirements for the variety: bar ±0.2mm for genuine, plate ±0.1mm for genuine (qualified) more than the waste.
The color, and pattern change, do not meet the requirements of the variety of waste products.
③ The model is bad, rotten edge, pumping core, and steam bubble are all waste products.
D. Production requirements and standards of buckle workshop
(1) The shape is consistent with the sample, including the size of the fine edge buckle and the camber of the face back.
② Inspection standards, there are the following phenomena are waste products:
a. Needle eye: the needle eye is broken, and cracked, the eye hole is not in the center of the button, the position of the four holes is not square, the eye hole is not perpendicular to the buckle surface, there are few holes after the broken needle or the needle is not pierced through, the front is big and the back is small, the dark eye button, the hole edge is blasted, there is no hole, etc.
b, buckle edge: one side thick, one side thin; The button is the right thickness overall, while the edges are thick on one side and thin on the other.
c. Compared with the overall thickness of the sample button, the overall thickness of the button becomes thicker or thinner, and four consecutive buttons become thicker or thinner when the machine is turning.
E. Acceptance standards of finished products
a) Standard of finished products

  1. The color, pattern, and model should be the same as the sample or the product.
    2, the pinhole is correct and symmetrical, and needle distance and pinhole size meet the standard.
  2. Luminosity meets requirements.
    4, face back without car explosion, the car is broken, uneven edge thickness phenomenon.
    5, according to the style, color, pattern, and type of packaging.

Production pattern

With the development of The Times, buttons from material to shape and production process are more and more colorful, and beautiful, data shows:
The buttons on the clothes of the Qing Dynasty are mostly small round copper buttons, big ones are like hazelnuts, and small ones are like beans. The folk uses plain noodles, that is, the surface is smooth and without lines. The court or aristocrats use large copper buttons or gilt bronze buttons, gold buttons, and silver buttons. Buttons are often engraved or carved with various patterns, such as coiling dragon patterns, flying phoenix patterns, and general patterns. Buttons are also pinned in different ways, with single, double, or triple rows.
After Qianlong, the production process of buttons is becoming more and more exquisite, clothes with buttons are more and more exquisite, and all kinds of buttons made of various materials have to meet the market, grotesque, fight win, everything. For example, there is a gold-plated buckle, silver-plated buckle, thread buckle, burning blue buckle, buckle, and so on. In addition, there are white jade hand buckles, gold-covered pearl buckles, three inlaid jade buckles, agate buckles embedded in gold and coral buckles, wax buckles, amber buckles, and so on, and even diamond buttons. Button decoration is also rich and diverse, such as broken branches of flowers, birds, and animals, Fu Lu jubilee, even the 12 zodiacs, and so on, which can be said to be everything, multifarious.

Distinguishing material

Button materials are roughly divided into plastic (resin, plastic), metal buttons (copper, iron, alloy), and natural (shell, wood, coconut shell, and bamboo. All kinds of materials to make buttons, but the process is not the same. Some buttons look the same, and even industry people with eyes may not be able to distinguish clearly, so damage, scrape the coat to distinguish.

Buttons distinguish plastic buttons and resin buttons, plastic buttons, and resin buttons, plastic (including a variety of plastic) buttons are generally die-cast, so there will be a line on the edge of the button, the mold line, some factories may remove this line in the subsequent processing, but its weight will be lighter than the resin (of course, some special plastic will be heavy). Resin buttons are mechanically carved and then polished, so there is no full mold line on the surface, very smooth. But it is fragile, scratches its surface easily, and softens when left in boiling water.

How can you tell a copper button from an iron button? : Copper and iron buttons, with a magnet to know, and use a hard thing to scrape the surface electroplating, copper buckle surface in the copper (gold). The iron buckle is black, which is the raw material color.

How to determine whether it is an alloy button? : Alloy buckle is relatively heavy, is made of die casting, all die lines, generally do grinding and polishing treatment, may not see, but it is very heavy, is solid.

Manufacturing process

Hardware buttons: open size mold (existing mold repair) — “Open button face mold (shape)/patterned mold (LOGO/ pattern, etc.) –” Mold test, sample out — “wool embryo –” oil washing/polishing — “electroplating –” other processing (oil/laser/screen printing, etc.) — “inspection/test –” packaging and delivery

Alloy buttons: drawing design drawings, carving copper, electric discharge machining, bulk mold, mold test, wool embryo, polishing/hand polishing, electroplating, other processing (oiling/laser/screen printing, etc.), inspection/test, packaging, and delivery

Inspection requirements and standards:

  1. Control the sample or confirm the sample. To see whether the color and model are consistent with the sample;
    2, the button surface should not have cracks, gaps, uneven and obvious scratches;
    3, face back without car crack, or bubble; No rotten edge, uneven thickness phenomenon;
    4, the pattern should have no obvious deformation, no white eyes, white circles, and other phenomena;
  2. Buttonholes should be smooth and smooth; The eye of the needle should be punctured and broken. It should be symmetrical and without a large eye. If it is a dark eye buckle, the dark eye groove should be smooth, with no obvious burst.
  3. After electroplating or other process treatment, the effect should be uniform. If some special effects cannot be consistent, they can be separately packaged.
    7, the same batch button color difference should not be less than GB250 four standard, compared with the sample, should not be less than GB250 three standard.
  4. Packaging inspection shall be carried out after the appearance inspection/performance test as required by customers are all qualified. A certificate of quality or another label should be placed in the package. The number of packages shall be following the regulations, and the actual quantity of each bag shall be following the regulations. If it is found that the thickness is different or other reasons exceed the allowance, the whole quantity shall be inspected.
    9, button/car button/five claw button before delivery to test button performance and availability, and provide mold and test samples to customers.
