Description
Technical Field
The utility model relates to a paper towel, in particular to a paper towel of a multilayer product.
Background
Paper towels are generally manufactured from natural and pollution-free raw materials such as wood pulp, bamboo pulp, cotton pulp, straw pulp and the like, and include paper towels, paper napkins, paper handkerchiefs, wet tissues, sassafras hand tissues, kitchen paper towels and the like according to purposes, and the paper towels can be divided into single-layer, double-layer and multi-layer structures according to the structures of the paper towels; the possibility that the multi-layer tissue is easy to delaminate and peel in the extraction process is that in order to change the delamination of the paper, the paper layers are adhered by embossing, the physical properties such as thickness, touch (surface softness), absorbency (fluffy softness) and the like of the tissue are also influenced in the embossing process, and the embossing process becomes a key link influencing the performance of the tissue in the paper making technology.
Embossed toilet paper structures currently on the market are mainly made by an embossing process and the bonding of the embossed toilet paper (embossed composite structures). The existing embossed toilet paper mainly adopts two-path embossing, and the existing three-path embossed toilet paper is restricted by the process, so that the existing three-path embossed structure product has no obvious advantages compared with a two-path embossed product.
CN201510439764.5 method for producing multi-layer embossed toilet paper, unwinding of base paper: unwinding the base paper to be embossed; fine embossing of the surface layer: leading one or more layers of surface layer base paper to an upper fine embossing roller pair for fine embossing to obtain fine embossed paper; rough embossing of the surface layer and the core layer: the obtained fine embossed paper and a layer of core layer base paper are rolled and led to a coarse embossing roller pair for coarse embossing to obtain coarse embossed paper, and a bonding agent is coated: leading the obtained coarse embossed paper to a roller pair consisting of a binding agent coated water rubber roller and a coarse embossed steel roller, and coating a binding agent on the side concave surface of the obtained coarse embossed paper core layer to obtain spot-gluing coarse embossed paper; bottom fine embossing: leading a layer of base layer base paper to a lower fine embossing roller pair for fine embossing to obtain base layer fine embossed paper; rewinding and packaging: and rewinding the obtained dispensing coarse embossed paper and the obtained bottom layer fine embossed paper, wherein the coarse embossed concave surface of the dispensing coarse embossed paper and the concave surface of the bottom layer fine embossed paper are bonded and connected in the rewinding process, and packaging to obtain the multilayer embossed toilet roll with the surface layer convex surface and the bottom layer convex surface which are opposite.
Although the scheme realizes three-path embossing of the surface layer, the core layer and the bottom layer, the existing three-path embossing structure product has no obvious advantages compared with a two-path embossing product due to the process restriction. The surface course, because receive twice knurling, the fibre juncture is destroyed by the tensile fracture of great degree in the toilet paper, leads to surface course toilet paper intensity low, easily rotten behind the wet water, causes user experience to descend. The structure formed by combining the surface layer and the core layer which are embossed twice cannot greatly improve the thickness structure of the product, and the change of the absorbency and the hand feeling is not obvious.
