Silk screen printing silicone for textiles and water-based silk screen printing ink for textiles each have their own unique usage methods in textile printing. The following are detailed steps and precautions for using these two materials on textiles:
1. How to use silk screen printing silicone for textiles
Preparation stage:
Choose a suitable screen. The mesh number of the screen should be determined according to the required printing effect. Usually, the mesh number of textile printing is between 80 and 120 meshes.
Prepare silk screen printing silicone of components A and B and ensure that their quality is qualified.
Mixing and dilution:
Mix silk screen printing silicone of components A and B in a certain proportion, usually using an electronic scale for accurate weighing.
As needed, an appropriate amount of diluent can be added to adjust the viscosity of the silicone to better meet the needs of textile printing. The amount of diluent added should be determined according to the type and brand of silicone to avoid excessive or insufficient amounts.
Printing preparation:
Place the mixed silicone in a vacuum machine for vacuum degassing to ensure that there are no bubbles in the silicone.
Pour the adjusted glue on the screen, gently push the screen evenly with a scraper, and prepare for printing.
Printing operation:
Place the textile on the printing table to ensure that it is flat and free of impurities.
Use a scraper to evenly apply the silicone on the screen and transfer the silicone to the textile through the mesh of the screen.
Maintain uniform pressure and speed of the scraper during printing to obtain a clear printing effect.
Drying and curing:
After printing, let the silicone dry naturally on the textile for a period of time, or bake and dry as needed.
The drying and curing time should be determined according to the type of silicone, the size and thickness of the printed pattern, and environmental conditions.
Subsequent treatment:
After drying and curing, the textile is subjected to necessary subsequent treatment, such as washing, ironing, etc.
Check the screen regularly to ensure that the screen is not blocked or damaged for the next use.
2. How to use water-based screen printing ink for textiles
Ink preparation:
Before use, the water-based screen printing ink needs to be fully stirred to ensure that components such as pigments and resins are evenly dispersed.
As needed, an appropriate amount of water or special diluent can be added to adjust the viscosity of the ink. The dilution ratio is generally not more than 10% to avoid the ink being too thin and causing a decrease in printing quality.
Screen preparation:
Choose a suitable screen. The number of meshes of the screen should be determined according to the fineness of the printed pattern and the fluidity of the ink.
Clean the screen to ensure that there are no impurities and residues on the screen.
Printing operation:
Pour the ink into the ink fountain and adjust the ink output of the ink fountain to meet the printing needs.
Use a scraper to evenly scrape the ink on the screen and transfer the ink to the textile through the mesh of the screen.
During the printing process, the pressure and speed of the scraper should be kept uniform to obtain a clear printing effect. At the same time, pay attention to controlling the amount of ink to avoid excessive or insufficient use.
Drying and curing:
After printing, let the ink dry naturally on the textile or use hot air drying and other methods to cure it.
The drying and curing time should be determined according to the type of ink, the size and thickness of the printed pattern, and the environmental conditions. Generally, water-based screen printing inks require a longer drying time to obtain good adhesion and wear resistance.
Subsequent treatment:
After drying and curing, the textiles are subjected to necessary subsequent treatment, such as washing, ironing, etc. When washing, neutral detergent should be used, and strong alkaline or strong acid detergents should be avoided to avoid damaging the printed pattern.
Check the screen regularly to ensure that the screen is not blocked or damaged for the next use. At the same time, pay attention to cleaning the printing equipment and tools to keep them clean and hygienic.
In summary, textile screen printing silicone and textile water-based screen printing ink each have their own unique use methods in textile printing. During use, it is necessary to strictly abide by the operating procedures and safety specifications to ensure printing quality and operational safety. At the same time, it is also necessary to select appropriate operating methods and precautions according to specific printing needs and material characteristics.
