16． Can pad dyeing of paint be carried out with resin in the dyeing and finishing bath method? What kind of resin and adhesive are better to choose?
Answer: Coatings and resins can be dyed and finished in the same bath, but the selection of resins and adhesives is still key. The difficulty is to solve problems such as the feel and wash fastness of medium and dark-colored products. A dyeing and finishing factory in Chengdu once used CPU resin ① as a cross-linking agent, polyurethane PU-1330 as a cross-linking film-forming agent and hydrophilic silicone CGF as a softener for pure cotton wick threads. , polyester/cotton poplin and other fabrics, the dark blue paint-resin dyeing and finishing one-bath method has been implemented, and good results have been achieved. This process can simplify the process and operation of coloring and finishing, and improve the depth and fastness of the paint. strength and fabric elasticity, improving hand feel and other characteristics.
The process flow: pre-treatment of semi-finished products, one padding and padding working fluid (two padding and two padding, padding rate 70% to 75%) → drying → baking (180℃, 30s)
Working fluid formula: Paint blue FFG 20g/L, urea 10g/L, Pingping O 2g/L, polyurethane PU-1330 50g/L, CPU resin 100g/L, magnesium chloride 10g/L, citric acid 3g/L, silicone CGF 2g/L . The physical indicators of the large sample are shown in Table 5-5.
