twenty four. What issues should be paid attention to when using amino silicone microemulsion finishing agent? How to clean the roller if it sticks?
Answer: There are many varieties of amino silicone microemulsion finishing agents, and their quality varies from good to bad. There are cationic, anionic, nonionic, etc., as well as modified amino silicon and linear amino silicon. However, in general, the following points should be paid attention to when using amino silicone oil.
① Do not pour more than 20% (solid content) high-concentration amino silicone microemulsion directly onto the running fabric. You should dilute the amino silicone oil in advance and pour it into the container. Stir evenly before adding it to prevent rapid adsorption. , causing silicone oil spots.
② Control the dosage. For example, for amino silicone oil with a solid content of 20%, the dosage of 1.5% to 3% (owf) is sufficient. Increasing the dosage will not increase the softness.
③The appropriate use temperature is 30~40℃. Although the temperature has no obvious effect on the softness and drape, when the temperature reaches 70℃, the elasticity changes greatly.
④The pH value of the impregnation or padding solution should be controlled at 5.5 to 6, which is beneficial to improving the softness, drape and elasticity of the fabric.
If the amino silicone microemulsion is used for too long, it will cause roller sticking, especially if it is of poor quality, it will even form a skin on the roller, affecting driving. Cleaning should be strengthened. Generally, XY-70 or leveling agent OP can be used. Dissolve it with hot water according to 1: (5~10) and then scrub it on the roller. Scrub it at least once per shift.
