Coating materials printing

There is another very important point in printing, only single-layer materials can be used for printing, and materials with layers cannot be printed, such as waterproof coating, etc. Because the printing process needs high-temperature heating, the temperature is generally 218.5 ℃. If the material cannot bear this temperature, it will melt. Therefore, it is impossible […]

Materials printing

In the process of material printing, temperature is also involved. Similarly, polyester material is easier to print, because polyester can withstand high temperature, and the requirement of accuracy of temperature control is not high. But nylon is not the same, because the nylon material is very sensitive to temperature, so if the temperature is slightly […]

Nylon dyeing

The dyeing of nylon material is much more difficult than that of polyester, because the temperature has a great influence on nylon dyeing, and nylon with different density also needs different temperature, so it is necessary to control the temperature very precisely in the dyeing process, which requires a good dyeing machine and a rich […]

Backpack cleaning method

If it is too dirty, the backpack can be washed with a neutral detergent and then placed in a cool place to air dry, but avoid exposure for too long, because ultraviolet rays will damage the nylon cloth. The specific method is as follows: Use a small brush to clean the floating soil, suitable for […]

New Materials Develop

There are limited materials or colors in the market, but not all the existing materials and colors are suitable for the backpack products you are developing, so new material development and color development will often be encountered in the product development stage. The development template given by the laboratory is only a small piece of […]

Elastic bands

Elastic bands are also often used in backpack parts, such as the opening of the water bottle pocket. The opening can be adjusted according to the size of the water bottle placed, and the water bottle can be better fixed. The computer bag will often be matched with the elastic band.
