The "water-expanding non-woven fabric" is a non-woven fabric made by fiberizing a polymer primarily composed of sodium polyacrylate, mixed with high water-absorbent and high moisture-absorbing fibers to impart water absorption properties. It quickly absorbs water due to its large surface area and does not easily release water even under pressure. With excellent moisture absorption and desorption properties, its capability is about twice that of silica gel. Additionally, it has strong light resistance, so there is no decrease in water absorption performance due to light exposure. It has high deodorizing properties against ammonia, allowing for repeated use through sun drying. There is no significant performance degradation even after repeated use. 【Features】 ■ Rapid water absorption speed ■ Excellent moisture absorption and desorption properties ■ Reusable ■ Excellent light resistance ■ High deodorizing performance *For more details, please refer to the catalog or feel free to contact us.
