A composite core material for paper diapers and its manufacturing method

Abstract

The invention discloses a novel composite core material for paper diapers and a preparation method of the novel composite core material. The novel composite core material is prepared from a fluffy non-woven fabric, a polymer absorbent material and dust-free paper, wherein wood pulp fiber is embedded into the bottom layer of the fluffy non-woven fabric. The novel composite core material has the advantages that the phenomenon that agglomerating and lumping are generated in the using process is effectively avoided; meanwhile, the fault phenomenon generated after longitudinal and transverse stretching is reduced, and the skin friendliness and the comfort degree are improved; after urine seeps downwards to arrive at the embedded wood pulp fiber, the urine diffuses around, therefore, the absorption speed of the urine is increased, the liquid absorption time of the polymer absorbent material is prolonged, and the reverse seepage amount of the urine is decreased.

Description

technical field [0001] The invention relates to a core material of sanitary products, in particular to a composite core material of paper diapers. Background technique [0002] In the existing technology, the core body of diapers is generally made of all-wood pulp material, because the core body made of all-wood pulp is prone to agglomeration and lumps during use, and the core body will be stretched vertically and horizontally. The problem of faults will reduce the comfort of diapers and affect the use of diapers. At the same time, the urine absorption speed and reverse osmosis of the core are also difficult problems that must be overcome. Therefore, it is necessary to improve and improve the core of diapers. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a composite core material for diapers and a manufacturing method thereof. [0004] The technical solution adopted by the present invention to solve the t...
