Embodiment 1

[0052] The total weight of the expanded core material in this example is about 90g / ㎡, and the thickness is about 2.3mm. The specific raw materials and structure are as follows:

[0053]Cellulose fibers are selected from Weyerhauser NB416 or International Paper Supersoft M or Georgia Pacific 4821, 4822, 4823 or their mixtures, and the fiber length is about 2-5mm;

[0054] Bicomponent composite fiber is an eccentric bicomponent composite fiber provided by fibervison, in which the core layer is polypropylene (PP) or polyester (PET), the skin layer is polyethylene (PE), and the fiber length is about 3-6mm. Denier is about 3.0-10.0 decitex.

[0055] The extruded core material consists of three layers. The weight of the first layer accounts for about 15% of the total weight of the product, the weight of the second layer accounts for about 40% of the total weight of the product, and the weight of the third layer accounts for about 45% of the total weight of the product. And spray th...

Abstract

The invention relates to a bulking core material and a manufacturing process and an application thereof. The structure of the bulking core material comprises (a) a first layer, (b) a second layer and (c) a third layer, wherein the first layer only contains eccentric type bicomponent composite fiber, and the first layer is quantified to be 10% to 40% of the total quantity of a product; the second layer which can be communicated with a liquid in the first layer contains cellulosic fiber and selectively contains concentric type or eccentric type bicomponent composite fiber which is the same as or different from that of the first layer, and the second layer is quantified to be 30% to 45% of the total quantity of the product; and the third layer which can be communicated with a liquid in the second layer contains cellulosic fiber and selectively contains concentric type or eccentric type bicomponent composite fiber which is the same as or different from that of the first layer, and the third layer is quantified to be 30% to 45% of the total quantity of the product. The bulking core material has the advantages of rapid permeability and dry and comfortable surface and has the high bulking performance, so that the product is very soft, the product level is increased, the production cost of producers is reduced, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a puffed core material with novel structure, fast penetration, instant dry surface and high fluffy performance, including the structure and manufacturing process of the puffed core material. Background technique [0002] Expanded core material (dust-free paper) is produced from several millimeters long wood pulp fibers through air-laid and different consolidation methods. This technology can produce a variety of materials with different thicknesses, softness, and hygroscopicity. Its products are mainly used in disposable sanitary products such as diapers, feminine hygiene products, and adult incontinence products. The speed of penetration is one of the important indicators of the performance of the expanded core material. [0003] Quick penetration means that the liquid stays on the surface of the product for a short time, and the liquid is transported to the functional layer in a very short time to keep the surface dry. The ...
