MULTI-PLY PLANAR ABSORBENT PRODUCT AND PROCESS FOR MANUFACTURING SUCH A PRODUCT

摘要

According to the invention differently coloured adhesive (a1, a2) is applied on both sides of a hydrophilic spunbond non-woven inner ply (B) of low grammage and no or low adhesion ability. Together with this inner ply (B) a three ply planar absorbent product is made with tissue outer plies (A,C) by exerting pressure on the coloured adhesive such that the adhesive penetrates through the inner ply (B) for achieving ply bonding between the inner ply (B) and the opposite outer ply (C). The dye pigments remain on the surface where the coloured adhesive is applied and shine through the adjacent outer ply in order to present a coloured design pattern on both sides of the product, wherein the different patterns do not disturb each other because the dye pigments do not penetrate through the inner ply (B).
