Problems solved by technology

[0005] Existing diaper products are often produced with multi-layer composite fabrics because of the need to ensure the water absorption performance of the core and the performance of moisture insulation and leakage prevention, which leads to thick and non-breathable diapers, especially in hot summer. Wrapped in wet and airtight diapers, it is easy to cause skin problems such as rashes and eczema

Abstract

The invention relates to the technical field of paper diapers, in particular to a paper diaper with high air permeability. The paper diaper includes an air permeability surface layer, a grid compositecore layer and a moisture absorbing outer layer from top to bottom; the grid composite core layer includes two layers of crimped moisture-proof non-woven fabrics and a plurality of water absorbing core bodies, the multiple water absorbing core bodies are distributed between the two layers of the crimped moisture-proof non-woven fabrics in a grid shape, and gaps are formed between any two adjacentwater absorbing core bodies. The paper diaper has the beneficial effects that two-component fiber spinning is of a spiral crimped structure, the crimped moisture-proof non-woven fabrics are providedwith fluffy structures, and air permeability is greatly enhanced; due to the fact that hollow structures are formed in the crimped moisture-proof non-woven fabrics, so the water storage capacity is strong, and a good moisture-proof ability is provided; and the gaps between the water absorbing core bodies ensures the absorption efficiency, and at the same time, excellent air permeability is brought.

Description

technical field [0001] The invention relates to the technical field of diapers, in particular to a diaper with high air permeability. Background technique [0002] Non-woven fabrics commonly used in diapers are also called non-woven fabrics, which are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Such as the disclosed non-woven fabric of CN206703628U, which discloses a hydrophilic and skin-friendly non-woven fabric. [0003] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0004] Two-component nonwoven fabric is a kind of nonwoven fabric, which uses two kinds of c...
