Fully coating ultrathin liquid absorption core and production method

Abstract

The invention relates to a fully coating ultrathin liquid absorption core and a production method. The fully coating ultrathin liquid absorption core enables polymer resin to be uniformly distributed between swelling non-woven fabric lines, can guarantee complete exertion of the liquid absorption performance of the polymer resin and can reduce the thickness of an absorption body effectively on the premise that the polymer resin is not required to be located by a fluff pulp carrier or an adhesive. The fully coating ultrathin liquid absorption core comprises a coating layer, wherein a liquid absorption layer is located on the coating layer, a covering layer is located on the liquid absorption layer, a flow guiding layer is located on the covering layer, and closing sides of the coating layer are located at the edge of the flow guiding layer. The fully coating ultrathin liquid absorption core has the following advantages: 1, fluff pulp is not required to be taken as a fixing substrate of the polymer resin, so that the thickness of the absorption body is reduced greatly, and the problem of non-uniform distribution of the polymer resin on the fluff pulp is solved; 2, the adhesive is not required to fix the polymer resin, and accordingly, the absorption capacity of the polymer resin is exerted sufficiently; 3, the production cost is reduced greatly, and the production efficiency is improved remarkably.

Description

technical field [0001] The invention relates to a polymer resin that can be evenly distributed between the textures of fluffed non-woven fabrics and can be used to position the polymer resin without the use of a fluff pulp carrier or an adhesive to locate the polymer resin. The invention relates to an all-inclusive ultra-thin liquid-absorbing core body which can fully utilize the liquid-absorbing performance of the resin and can effectively reduce the thickness of the absorber itself, and a manufacturing method thereof, belonging to the field of absorber manufacturing for hygienic products. Background technique [0002] CN 104367418A, titled "a composite absorbent core", includes a surface layer, a bottom layer, and an intermediate absorbent layer arranged between the surface layer and the bottom layer, and a plurality of longitudinal perforations are opened on the intermediate absorbent layer. The longitudinal perforations are filled with polymer water-absorbing resin. Its...

AI Technical Summary

Problems solved by technology

Its disadvantages: Since the middle absorbent layer is perforated longitudinally, it is impossible to cover the polymer resin, and the bottom layer needs to be specially covered, and it is impossible to realize the production and cutting of large-area composite non-woven fabric cores

Its shortcomings: First, because the polymer resin cannot be uniformly combined with the bulky non-woven fabric, the resulting polymer composite core absorbs the uneven surface formed after absorbing the liquid, which makes the user feel uncomfortable; It is because the bulky non-woven fabric is used to fix the base material of the polymer resin, which is not only thick, but also cannot effectively position the polymer resin
