Online thermal composite quick infiltration guide material

Abstract

The invention provides an online thermal composite quick infiltration guide material. The online thermal composite quick infiltration guide material comprises a quick infiltration guide layer and a dust-free paper layer which are communicated with each other by virtue of liquid; the quick infiltration guide layer is prepared from a porous nonwoven material and accounts for 8 to 85 percent of the total weight of the composite quick infiltration guide material; the dust-free paper layer comprises at least one fiber layer, the fiber layer is prepared from cellulose fibers and dual-component composite fibers, and the dust-free paper layer accounts for 15 to 92 percent of composite guide material dust-free paper; the cellulose fibers in the fiber layer account for 5 to 95 percent of the total weight of the fiber layer, and the dual-component composite fibers account for 5 to 95 percent of the total weight of the fiber layer; and when the layer number of the fiber layers is two or more, the two adjacent fiber layers are communicated with each other by virtue of liquid. A sanitary towel product prepared from the composite quick infiltration guide material is loose, soft, good in resilience, low in production cost, good in overall performance, simple and novel in structure, not only capable of quickly guiding, infiltrating, dispersing and temporarily storing the liquid, but also excellent in back-permeability resistance.

Description

technical field [0001] The invention relates to a fluffy and soft, good resilience, low production cost, good overall performance, simple and novel on-line thermal compound rapid permeation diversion material, which has the functions of rapid liquid diversion, rapid permeation, diffusion and temporary storage of liquid, and has A composite diversion material with excellent back seepage resistance performance, including the structure, production process and application of the composite rapid seepage diversion material. Background technique [0002] Dust-free paper (also known as puffed core material) is produced from wood pulp fibers with a length of several millimeters as the main raw material 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 incontin...

Problems solved by technology

However, due to the addition of polymer water-absorbing materials to the composite dust-free paper, in order to ensure the bonding strength between the bottom liner and its adjacent layers, it is necessary to add powdery or granular bonding materials at the same time, and it is necessary during the production process. Higher pressure, although it increases the bonding effect, will affect the bulkiness, rebound performance and diversion effect of the material, and also increase the cost of raw materials; another disadvantage is that the powdery bonding material increases the control complexity of the production process During the forming process, a small amount of powdery bonding material will penetrate through the backing material due to vacuum (when the vacuum degree fluctuates greatly, there will also be a phenomenon of powdery bonding material passing through), which will affect the pores of non-woven materials. which in turn affects the quality of the entire product

In addition, in the production and use of sanitary napkins, the size of the diversion composite dust-free paper needs to be the same as the surface area of ​​the sanitary napkin, and the core area of ​​the absorbent layer of the general sanitary napkin is smaller than the surface layer, so the composite dust-free paper is used Paper will result in the waste of some raw materials
