Abstract

The invention discloses a surface coating used for a low-radiation antibacterial cotton fabric capable of releasing negative oxygen ions. The coating includes, by weight, 2-20 parts of rare earth negative ion materials, 5-20 parts of sodium sulfate, 0.1-2 parts of a penetrant, 0.1-2 parts of a stabilizer, 10-40 parts of a binder and 3-10 parts of a cross-linking agent. At the same time, the invention further discloses a preparation method and use method of the surface coating used for the cotton fabric. The made cotton fabric has the function of being capable of releasing negative oxygen ionspermanently, sterilization and bacterium inhibition can be achieved effectively, the antibacterial ratio can reach 95% or above, 3500 activated negative oxygen ions exist per square centimeters, radioactive elements Ra-226 are removed, and the safety characteristics of the product are ensured to the greatest extent.

Description

technical field [0001] The invention belongs to the field of cotton textile fabrics, and in particular relates to a surface coating for cotton fabrics capable of releasing negative oxygen ions and antibacterial with low radiation, a preparation method and a use method thereof. Background technique [0002] Most of the current negative ion textile fabrics adopt the post-finishing method, which does not have the characteristics of water resistance, and due to the addition of negative ion nano-powders, the radioactive elements in the negative ion raw materials have not been removed, and most of them have safety problems such as radioactivity exceeding the standard. Cotton textile cotton It is widely used as raw materials for textile products such as bed sheets, quilt covers, and underwear. [0003] The negative ion textile fabrics produced by the post-finishing method do not have the performance characteristics of washing resistance, do not meet the application scenarios of neg...
