Garment Hot Stamping And Its Quality Identification Method

Factors affecting the hot stamping: first, the quality of hot drilling and hot stamping; the two is the quality of hot stamping.

I. factors affecting hot stamping -- identification of quality of hot stamping and hot stamping

The quality of hot drilling and hot stamping (octagonal and flat) is distinguished from four aspects:

One is brightness.

Good quality, good brightness, poor quality and poor luminance.

The two is chromatic aberration: high quality, pure color, low chromatic aberration, poor quality, bad color and large chromatic aberration.

The three is the specifications: high quality, thick and thin, the same diameter; poor quality, uneven thickness, large diameter and small diameter.

The four is the base glue: the quality is good, the base glue is thin and round, the color is consistent; the quality is bad, the bottom glue is thick and irregular, the color is deep, shallow, even many have the lack of base glue.

According to the ironing effect, the bottom glue is not easy to fall off, and the bottom glue is easy to fall off, especially after the water is seen.

At present, the market has imported, semi imported (foreign materials domestic processing or domestic materials foreign technology), domestic three kinds of drilling pieces.

The import is the best, the semi import is better, the domestic one is generally.

Because the technical indexes of drill pieces produced by different factories are different, the state has not inspected, so in the absence of grade standards, manufacturers and distributors will label themselves according to market comparison, purchase price and business needs, so that the quality and price of diamond chips will be confused and difficult to identify.

Two, the impact of hot stamping reasons - ironing paper

There are only two kinds of white ironing paper and yellow ironing paper on the market, each has its own advantages.

White blanching paper is divided into coarse grain, middle grain and fine grain.

Generally speaking, because of the grain on the bottom of the white paper, the drill bits are not easy to walk, while the yellow hot paper has good viscosity, but the bottom paper is slippery, which is suitable for hot stamping.

Therefore, we should choose hot paper according to the drill piece.

Three, the influence of hot stamping factor - mold making

Mold making is the key to hot stamping.

There are two ways to make the mold. One is the mechanical drilling machine. The drawback is that it can only mold the circular drill. The accuracy of the graphics depends on the experience of the mold maker.

The two is computer laser molding (computer engraving machine and laser machine), which can be made according to the pattern, but not at all, but the cost is higher.

Four, the influence of hot stamping factor - processing

Rough machining and fine processing are all done by hand.

Rough machining is based on the general processing of incoming samples, and the inspection is not meticulous. Finishing is about the quality of processing, careful inspection and acceptance, replacement of chromatic aberration, damaged, missing glue, and shifting drill pieces, so that graphics remain the same as the effect picture.

Use time to calculate, rough processing three maps, finishing up to two.

Five, the influence of hot stamping factor - packaging

The outer packing includes vacuum plastic paper packaging and carton packing. The packing is very critical. Generally, it is packed in newspaper, the number of sheets should be appropriate, the tightness should be moderate, the packaging for long-distance pportation should be clipped with hard paper, or wrapped in cardboard around four corners, so that the hot stamping and drilling pieces can not be removed.

Six, the influence of hot stamping factor - Transport

Hot stamping pport should be specially protected, gently handled, not to be knocked down, long distance pportation should be insured and careful care must be taken to ensure that graphics do not go away.

Seven, the influence of hot stamping factor - ironing method

Hot stamping, steam ironing, ironing, laser ironing, iron ironing and so on.

Generally speaking, ironing is mainly combined with three elements of temperature, time and pressure.

The melting point (octagonal, flat film) melting point is 140 degrees, so the temperature must reach 140 degrees centigrade to be hot. The temperature of homemade drilling is low, generally around 140 degrees Celsius; the temperature of imported drilling is high, usually at 160 C - 200 c; the diameter of the drill is low, and the diameter of the drill is very high.

The time is usually 10 seconds to 15 seconds.

The pressure should be moderate, depending on the cloth.

In general, when heated from hot paper, the thin material can also be heated from the cloth surface.

The temperature of the thin material should be lower, the temperature of the thick material should be higher, the neat clothes should be ironed, and the clothes with different thickness and different sizes should be made of elastic cushions, and the pressure should be slightly larger before they can be ironed.

The most notable thing is to scald colored Chinese made octagonal slices and white slices with steam on white clothes, so that white clothes can be dyed easily.

Because apart from white and yellow ironing, all other color plates fade, but they can not be seen in colored clothes.

Printing on the hot stamping required printing design should be small holes in the drill hole to burn well, otherwise the drill piece is easy to fall off.

Eight, the influence of hot stamping factor - Inspection and acceptance

Check before hot and check after hot.

All drills (including imported ones) are more or less chromatic aberration, broken, missing glue, drill bits, or even lack of drill pieces. Therefore, they must be inspected and corrected before ironing.

If you want to see the ironing, you can see if it is hot. First, if there is a phenomenon that there are not many ironing pieces, increase the temperature immediately, extend the heat and increase the pressure once again. If there are individual unheated bits, replace them with a clip and put them on the cigarette butts, on the lighter or on the ironing machine, then put them directly on the cloth, then press them. Two, after heating, use the appropriate power to scrape the scraps on the hot drawing. If the scraps are not finished, the drill pieces will be heated. If the drill bits are scraped, they should be redone.
