The application of additive two component liquid silicone on women's underwear
The additive liquid silicone is made of vinyl containing base glue (base substance) and hydrogen containing silicone(cross linking agent) catalyzed by platinum-series compounds, and cured at room temperature or medium temperature conditions cross-link to be elastomer. The structural equation as follows:
Based on the above reaction principle, the formed liquid silicone is generally divided into two components for packaging, such as base material + cross-linking agent as component A, platinum catalyst as component B (deployment ratio of 100:2); Base material + platinum catalyst as component A, cross-linking agent + others as component B (10:1 ratio); Or base material + platinum catalyst as component A, base material + cross-linking agent as component B (deployment ratio 1:1). Before use, stir evenly according to a certain proportion, and then apply to the product processing process.
This article mainly introduces how to apply the two-component (1:1 deployment ratio) AB adhesive in the process of women’s underwear fabric fitting.
Benefits of silicone for underwear fitting
Traditional underwear is mostly stitched with needle and thread. As underwear products increasingly require elastic and comfortable fabrics, needle and thread are not suitable for high stretch, so underwear fitting silicone comes into being. The liquid silicone is evenly printed on the surface of the underwear cut piece, and then the two cut pieces are compounded (fitted) together, placed in the closed oven, after slightly heating up, the silicone cross-linking and curing into the link layer, which can effectively fit the two pieces of fabric closely together, and can be highly stretched, elastic, comfortable and good water-resistant.
How to use AB two component liquid silicone
As mentioned above, the forming liquid silicone can be made of base glue + platinum catalyst as component A, base glue + cross linking agent as component B, before use, mix together in 1:1 ratio, through the screen plate (machine print or hand print) evenly printed on the surface of underwear cut piece,and then neatly fitted with another same cut piece , placed in the oven and cure, The semi-finished product go through other processes to become a tight fit, moderate elasticity, comfortable underwear.
Other component silicone for fitting women's underwear
According to the operation habits of the underwear workshop, our company produces the mixture ratio of 100:2 and 1:1, and the single component (platinum built-in) additive silicone, and can adjust the hardness, tensile degree, fit degree and clarity of the silicone (after curing) according to the workshop's requirements.
