Thermal composite rapid infiltration diversion material and application thereof

Abstract

The invention provides an on-line thermal composite rapid infiltration flow guide material and application thereof. The on-line thermal composite rapid infiltration flow guide material comprises a rapid infiltration flow guide layer and a dust-free paper layer which are in liquid communication with each other, the rapid infiltration flow guide layer is made of a porous non-woven material and accounts for 8-85% of the total mass of the composite rapid infiltration flow guide material; the dust-free paper layer comprises at least one fiber layer, the fiber layer is made of cellulosic fibers and bi-component composite fibers, and the mass of the dust-free paper layer accounts for 15-92% of the total mass of the composite flow guide material dust-free paper; the mass of the cellulose fibers in the fiber layer accounts for 5-95% of the total mass of the fiber layer, and the mass of the two-component composite fibers accounts for 5-95% of the total mass of the fiber layer; when the number of the fiber layers is two or more, the adjacent fiber layers are communicated through liquid. A sanitary napkin product prepared from the composite quick-seepage flow guide material is fluffy, soft, good in rebound resilience, low in production cost, good in overall performance and simple and novel in structure, not only has the functions of quick liquid flow guide, quick seepage, diffusion and temporary liquid storage, but also has excellent reverse seepage resistance.

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
