Abstract
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...
Examples
Embodiment 1
[0021] A kind of antibacterial nonwoven fabric for diapers, pretreatment of spunbonded polypropylene nonwoven fabric with vacuum plasma, and then combining chitosan oligosaccharide on the surface of nonwoven fabric in the form of dip coating, the preparation of the antibacterial nonwoven fabric Include the following steps:
[0022] 1) Non-woven fabric pretreatment: Soak polypropylene spunbonded non-woven fabric in absolute ethanol and store at room temperature for 24 hours, squeeze dry and replace with deionized water to remove ethanol in the non-woven fabric, and put it into Dry in a blast drying oven at 60° C. to obtain a polypropylene non-woven fabric without impurities; then the non-woven fabric is subjected to plasma treatment for 5 minutes under the condition of a vacuum plasma power of 100 W.
[0023] 2) Preparation of chitosan oligosaccharide finishing solution: Weigh the chitosan oligosaccharide prepared by enzymolysis with an average degree of polymerization of 10 an...
