Abstract

The invention relates to the field of disposable hygienic products, and provides a preparation method of a chitosan fiber non-woven fabric applied to the surface layer of a paper diaper, and the preparation method comprises the following steps: 1) preparing N-carboxyethyl chitosan; (2) preparing modified chitosan; (3) preparing modified chitosan fibers; and (4) preparing the chitosan fiber non-woven fabric. The prepared chitosan fiber non-woven fabric can effectively prevent diaper rash and better protect baby skin.

Description

Technical field [0001] The present invention relates to the field of disposable toiletries, and more particularly to a method for preparing a chitosan fiber nonwoven fabric applied to a surface of the diaper. Background technique [0002] Urine rash is a common skin problem. It is an inflammation that has a symptom of hip skin, a phetten, a blisteroid, severe or even erosion, and oozing. There are many factors that cause urinary rash, including: (1) friction between skin and diaper, causing damage to the skin keratinic layer; (2) Local wet heat causes excessive hydration of the skin; (3) the ammonia gas generated by urine or excrement decomposition Stimulation; (4) bacterial infection. [0003] There are problems in the existing diapers used, and diapers that produce prevention of urinary rash are the urgent desire of consumers. However, there is only a small amount of diapers that prevent urinary rash, such as patent application NO: 201610333747.8 discloses diaper production met...
