How to ensure that the color of the silicone thermal transfer label of the riding pants remains stable under different lighting conditions?
To ensure that the color of the silicone thermal transfer label of the riding pants remains stable under different lighting conditions, you can start from the following aspects:
Material selection
Silicone: Choose silicone material with high light resistance. High-quality silicone itself has a certain resistance to light such as ultraviolet rays, which can reduce the color change caused by light. For example, silicone containing special additives or modified treatments can enhance its light aging resistance.
Ink: Use ink with high light resistance for thermal transfer. The light resistance index of ink is very important. Generally, you can refer to its rating under relevant standard tests and choose products with high ratings. For example, ink containing ultraviolet absorbers, light stabilizers and other ingredients can effectively absorb or stabilize light energy to prevent the color from decomposing or fading due to light.
Transfer paper: Choose high-quality transfer paper with good compatibility with ink and silicone. High-quality transfer paper can ensure that the ink is evenly transferred to the silicone during the transfer process, and in the subsequent lighting environment, it will not affect the color stability due to adverse reactions with ink or silicone.
Production process control
Ink mixing: Precisely control the mixing ratio of ink. The mixing ratio of different color inks must be strictly implemented according to the formula. Slight deviations may cause differences in the stability of the color under light. At the same time, ensure that the ink is stirred evenly so that the various components are fully integrated to avoid affecting the color performance due to uneven local components.
Heat transfer parameters: Precisely control the temperature, pressure and time of heat transfer. Too high temperature or too long time may cause excessive reaction between ink and silicone, affecting color stability; too low temperature or too short time may cause insufficient ink transfer, which is also not conducive to color retention. For example, according to the different characteristics of silicone and ink, the heat transfer temperature is controlled at 130-160℃, the pressure is controlled in an appropriate range, and the time is controlled at 10-20 seconds.
Curing treatment: After heat transfer, the silicone is properly cured. Through a suitable curing process, the ink and silicone are firmly combined to form a stable structure and enhance the color's ability to resist light. For example, ultraviolet curing or heating curing is used to ensure that the curing process is uniform and sufficient.
