Problems solved by technology

The Chinese patent of patent number 201110431244 proposes to set water-soluble chitosan solid particles on the absorbing layer, which can be dissolved in water to exert antibacterial properties, but the granular water-soluble chitosan has limited solubility, and the dosage is relatively large, which wastes resources. Uneven distribution leads to poor antibacterial performance

Abstract

The invention discloses a bacteriostatic non-woven fabric for a paper diaper, and relates to the technical field of novel functional materials. Spun-bonded polypropylene non-woven fabric is preprocessed by vacuum plasma to be subjected to activation, and therefore dip-coated chitosan oligosaccharide can be combined with the surface of the non-woven fabric, and the manufactured bacteriostatic non-woven fabric is used for a surface layer, making contact with the human skin, of a paper diaper body. The paper diaper surface layer non-woven fabric manufactured according to a method does not requirea chemical cross-linking agent, has the good air permeability and the good moisture permeability and also can effectively inhibit microorganisms from breeding. Compared with the prior art, the bacteriostatic non-woven paper diaper made of the bacteriostatic non-woven fabric has the advantages of being bacteriostatic, skin-friendly and environmentally friendly and being free of pollution. Meanwhile, the antistatic performance and the moisture absorption performance of the non-woven fabric are improved to a certain extent compared with the performance of a common product, and the comfort of theproduct is improved.

Description

technical field [0001] The invention relates to the field of new functional materials, in particular to an antibacterial nonwoven fabric used for diapers. Background technique [0002] It is estimated that by 2025, China's elderly population over the age of 60 will exceed 300 million. The arrival of an aging society has brought rigid demand for some elderly care products. The proportion of the elderly in China using adult diapers is only 1.0%, which is far below the world average of 12%. The production of high-quality adult diapers or nursing pads and related products has important social significance. [0003] Diapers that are not replaced in time tend to form a humid and stuffy environment, which is very easy to breed bacteria and produce a large amount of ammonia gas, which will increase the pH, irritate the skin, cause skin diseases or cause skin infections of patients, which is not conducive to health . Therefore, diapers should be endowed with antibacterial and anti...
