Problems solved by technology

However, various pharmaceutical preparations are sprayed on the surface material of baby diapers or adult diapers, that is, non-woven materials. Due to problems such as uneven spraying and poor washability, the bactericidal effect of urine is reduced by 60% after passing through the non-woven materials once. , almost no bactericidal effect after two

Abstract

The invention relates to a preparation method for nano-silver antibacterial non-woven fabric and application of the nano-silver antibacterial non-woven fabric to baby and adult diapers. The preparation method for the nano-silver antibacterial non-woven fabric comprises the steps of preparing antibacterial polyethylene (PE) masterbatch, preparing antibacterial ethylene-propylene side by side (ES) fiber, loosing cotton, shaping and the like. The preparation process is simple and cost is saved. In the nano-silver antibacterial non-woven fabric, nano-silver ions are modified and can be distributed into non-woven fiber uniformly to form an antibacterial high-tech material which can be stored for more than five years normally, can effectively inhibit bacterial growth for a long time and has a long-acting physical sterilization function and a unique self-cleaning function.

Description

technical field [0001] The invention relates to the field of daily hygiene products, in particular to a preparation method of nano-silver antibacterial nonwoven fabric and its application in baby diapers and adult diapers. Background technique [0002] Non-woven fabrics are widely used in infant diapers, adult diapers and other products due to their advantages of light weight, degradability and low cost. In order to effectively inhibit the growth of bacteria, a lot of improvements have been made to the production process of non-woven fabrics. At present, the most used method is to spray various pharmaceutical preparations on non-woven materials to achieve antibacterial effect. However, various pharmaceutical preparations are sprayed on the surface material of baby diapers or adult diapers, that is, non-woven materials. Due to problems such as uneven spraying and poor washability, the bactericidal effect of urine is reduced by 60% after passing through the non-woven material...
