Problems solved by technology

This patent uses silk fiber fabric as the surface layer of sanitary napkins. Although it has good wearability, the price of natural silk is high, which makes the sanitary napkins have a narrow audience.
[0009] In summary, the baby diapers prepared by the method for preparing baby diapers provided by the prior art have the problems of low strength, and the hydrophilic non-woven fabric on the surface is easy to fluff and shed, which poses a great threat to the health of infants. Moreover, the baby diapers prepared by the baby diaper preparation method provided by the prior art also have problems such as high raw material price, high production cost, and poor dryness and comfort. When used next to the skin, the comfort of the human body in the microenvironment cannot be improved. Therefore, The invention provides a baby diaper and a preparation method thereof

Abstract

The invention discloses a baby paper diaper and a manufacturing method thereof, and relates to the field of disposal sanitary products. The baby paper diaper is mainly prepared by adopting modified polypropylene ultra-fine fiber non-woven fabric film as a surface layer hydrophilic non-woven fabric, a thickening fluffy type flow guiding layer non-woven fabric, an absorption layer and an impermeable bottom layer. The manufacturing method of the baby paper diaper comprises the steps that a polypropylene section with the melting index being 25-40 g / 10 min is adopted, and the modified polypropylene ultra-fine fiber non-woven fabric film is prepared by adding a chain breaking agent and a hydrophilic agent to be adopted as the surface layer non-woven fabric of the baby paper diaper, so that the strength of the baby paper diaper is improved, polypropylene ultrafine fiber in the modified polypropylene ultra-fine fiber non-woven fabric film reaches the semi-plasticized state by reasonably selecting the plasticizing temperature and pressure, the manufactured baby paper diaper has the good flexibility, good moisture permeability and good skin friendliness, is not likely to shed fiber, and creates a soft, comfortable and dry micro-environment for a baby when in use.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a baby diaper and a preparation method thereof. Background technique [0002] With the change of the consumption concept of the new generation of young parents and the introduction of the two-child policy, the domestic consumer demand for baby diapers has shown a strong trend, making the baby diaper industry a market with huge room for development. The baby diapers currently on the market are mainly composed of the surface layer, the diversion layer, the absorbent core layer, the leak-proof bottom film and the hot-melt adhesive bonding the various parts together [Xu Xiaoping. Structural properties of multi-layer materials for baby diapers and penetration mechanism research [D]. Donghua University, 2013.]. When urine is injected into baby diapers, the first contact is the surface layer, and then it is absorbed by the middle core through the diversion layer. The surface...
