In principle, hot-stamped trademarks on clothes are almost impossible to remove without leaving traces.

First of all, you need to look at the size of the hot stamped trademark on the clothes. If it is large, there is no need to worry about it. If the area of ??the hot-stamped trademark on the clothes is very small, it depends on whether the hot-stamped trademark on the clothes penetrates into the clothes, or floats on the surface like glue. If it penetrates into the fabric, don't worry about it.

If it is glue, you can try the following methods:

Try using high-temperature water. Usually some of the hot-stamped trademarks on the clothes will be removed, but it will be more unsightly; the best way is: Ask someone to use dark paper (heat transfer) to print a pattern on the original place, or print a heat transfer inside the American foam, and it can be completely covered without being removed; if the clothes are solid color, you can use Try washing the stains. If there are a lot of colors, don't wash them.

Types of fabric hot stamping technology

Fabric hot stamping technology has developed rapidly in my country, but it was only put into mass production after 2000. With the rapid development of science and technology, the fabric hot stamping process has become increasingly mature. Because the overall effect of the hot stamped fabric looks elegant and trendy, it has become more and more popular among many beauty lovers.

With the continuous development and updating of hot stamping technology, fabric hot stamping has become a subdivided industry. Taking hot stamping equipment and hot stamping methods as an example, there are generally two types of common hot stamping equipment:

1. Round fabric hot stamping

Both the hot stamping plate and the relief plate of the bottom mold are cylindrical, and there is line contact between the two cylindrical rollers. The relief plate of the bottom mold is generally made of silica gel with moderate hardness. material. This hot stamping machine is suitable for hot stamping entire rolls of narrow-width rolled cloth strips. The advantages are: fast speed and high output.

The hot stamping paper used usually has a metal coating on the back and also comes with a hot stamping adhesive. As long as the gold foil paper is properly selected and the various performances of the hot stamping machine are debugged accurately, the cloth strips will be hot stamped. Fastness is basically okay.

But there is also a disadvantage. Since the fabric has more or less tension, during the hot stamping process of the entire rolled cloth strip, the cloth strip and the hot stamping paper are moving at the same time. When color hot stamping, it is difficult to control the accuracy of color registration. At this time, we can only settle for the next best thing, first do the single color hot stamping well and achieve the ultimate.

2. Flat stamping of fabrics

The more common hot stamping machines are: pneumatic hot stamping machine or manual hot stamping machine. The main components are composed of two upper and lower metal plates. When doing fabric hot stamping, generally, the upper aluminum plate generates heat and moves downward. The pressure and time that need to be considered when hot stamping depend on the height of the glue layer of the printed pattern and the temperature that the fabric can withstand.

In most cases, the temperature is between 140°~160°, the pressure is more than 5kg, and the time is 10 seconds (reference value). If the temperature is too low, the hot stamping fastness will not be ideal; conversely, after the fabric is hot stamped, the surface of the cloth will turn red (white cloth will turn yellow) and change color. If the pressure is too low, the fastness will be affected; if it is too high, the pattern of the three-dimensional hot stamping paste will collapse and the three-dimensional effect will be lost.

When using this method to hot stamp fabrics, there is a prerequisite: add hot stamping glue with a screen plate, print the pattern you need on the surface of the fabric in advance, and wait until it is completely dry before entering the hot stamping machine. Do fabric foil stamping. After hot stamping, set aside to cool completely, tear off the scrap gold foil → inspect → repair → package to complete the entire fabric hot stamping process.
