Before screen printing clothes,you need check the clothes material.If it's cotton blender,you can print silicone ink directly without undercoating.It's well-known that the cotton blender has more fuzz.You should print the clear high density silicone ink for two times,and press the fuzz with pressing machine.We recommend you press it at 150-160℃,about 15seconds.
Silicone ink printing on waterproof fabrics is a popular printing technique in the textile industry. However, achieving high density printing with excellent stick force, abrasion resistance, and glossy/matte finishes can be a challenge for many manufacturers. In this article, we will outline the steps necessary to make high density screen printing with silicone ink on waterproof fabric with higher stick force, as well as how to improve abrasion resistance with glossy or matte silicone.
Step 1: Choose The Right Silicone Ink
The first step in achieving high density screen printing with silicone ink on waterproof fabric with higher stick force is choosing the right ink. There are two types of silicone ink - platinum-cured silicone ink and tin-cured silicone ink. The platinum-cured silicone ink is durable, resistant to heat, and has a fast curing time. The tin-cured silicone ink is cheaper, has a slightly longer curing time, and is used for thicker screens or more intricate designs. Depending on the project, one of these inks may be a better option for achieving the desired results.
Step 2: Prepare The Fabric
To ensure a successful printing process, the fabric must be properly prepared. Waterproof fabrics are often coated or laminated, which can make it difficult for the ink to adhere to the fabric. The fabric must be cleaned thoroughly to remove any dirt, oil, or debris that may interfere with the adhesion of the ink. Once the fabric is cleaned, it should be allowed to dry completely before printing.Meanwhile,you need print silicone adhesive XG-360Z-3X for undercoating about 2-3 times.
Step 3: Create The Screen
The next step is to create the screen. It's thick screen with 120 mesh.The screen mesh used should be fine enough to create a crisp image, but not so fine that the ink cannot penetrate. The ink should be applied to the screen evenly and with the appropriate thickness to achieve the desired density. Additionally, the screen should be exposed to a light source for the appropriate amount of time to ensure proper curing.
Step 4: Print The Fabric
Before beginning the printing process, it is important to ensure that the ink is properly mixed and that the printing area is free of dust and debris. High density printing is achieved by multiple passes of ink. Between each pass, the ink should be allowed to dry completely. We recommend the baking temperature at 90-100℃ for water-proof fabric if the fabric is not good heat resistance.You must add more catalyst at low temperature.You can add 6-8% catalyst by weight of ink base.The printer should also pay close attention to the amount of ink being used per pass, and ensure that the thickness is even across the entire design.
Step 5: Curing
Once the fabric has been printed, it must be cured in order to achieve the desired stick force and abrasion resistance. You can bake the printed fabric for 3-4 times with automatic oven on table ,or use the conveyer oven to bake one time at 100℃.The curing process is essential to ensure that the ink properly adheres to the fabric and is resistant to fading, chipping, and peeling. The most common method of curing silicone ink is through heat. The temperature and duration of the curing process will vary depending on the ink and fabric being used. It is important to follow the manufacturer's recommendations for curing in order to achieve the desired results.
Improving Abrasion Resistance with Glossy or Matte Silicone
To improve the abrasion resistance of silicone ink on waterproof fabric with a glossy or matte finish, manufacturers can use additives during the curing process. The addition of a gloss or matte finish agent provides additional protection to the ink, making it more resistant to wear and tear. The choice of a gloss or matte finish will depend on the desired look and feel of the finished product.
In conclusion, high density screen printing with silicone ink on waterproof fabric with higher stick force and glossy/matte finish is achievable with proper preparation, selection of the right ink, creating the right screen, printing, and curing with the correct temperature and duration. Manufacturers can achieve the desired abrasion resistance by incorporating gloss or matte finish agents during the curing process. With these steps, manufacturers can produce printed waterproof fabrics with excellent adhesion, resistance, and long-lasting results.
