Description

Kitchen paper

Technical Field

The utility model belongs to the technical field of the household paper, specifically be a kitchen paper.

Background

The kitchen paper is a paper towel specially used in a kitchen as the name suggests, has thick hand feeling and good water and oil absorption. Compared with traditional rags, the kitchen paper is more sanitary and convenient, and is more and more popular with consumers in the aspects of household cleaning and the like.

With the improvement of living standard, the functional requirements of people on the household paper are higher and higher, and on the premise of meeting the functions of water absorption, wiping and the like, the paper is required to have good strength, difficult breakage and no paper scrap residue, and the paper is required to have good use hand feeling and pleasant mood. These requirements are reflected in paper physical properties, namely, indexes such as paper strength, softness, water absorption, bulk, and dusting rate. High grammage, increased paper strength, poor flexibility, and good water absorption with large thickness. The softness is good, and the fiber hair and powder falling probability is increased.

However, the prior art kitchen paper has the following disadvantages in use: the water absorption and locking performance is not ideal, under certain gravity wiping conditions, the wiped liquid is caused to return to the surface, the cleaning efficiency is reduced, and hands are easily polluted.

Disclosure of Invention

For solving the technical problem that exists among the above-mentioned prior art, the utility model discloses a layer is fine and close feels soft smooth, and the inlayer absorbs water the novel kitchen paper that the lock water performance is excellent.

The utility model discloses a concrete technical scheme as follows:

the kitchen paper comprises upper and lower layers of base paper, and a hollow layer and a glue layer are arranged between the upper layer of base paper and the lower layer of base paper.

Preferably, the upper layer base paper and the lower layer base paper comprise an upper surface layer and a lower surface layer, the upper surface layer is made of bleached hardwood chemical pulp, and the lower surface layer is made of bleached softwood chemical pulp and high-yield mechanical pulp.

Preferably, the weight ratio of the upper surface layer slurry to the lower surface layer slurry is 0.67-1.86: 1.

Preferably, the weight ratio of the bleached softwood chemical pulp to the high-yield mechanical pulp is 0.11-0.33: 1.

Preferably, the two lower surface layers of the upper base paper and the lower base paper are arranged oppositely.

Preferably, the hollow layer and the glue layer are uniformly distributed between the upper layer base paper and the lower layer base paper in a dotted shape.

Preferably, the hollow layer and the glue layer are arranged at intervals.

Preferably, the basis weights of the upper layer base paper and the lower layer base paper are the same.

Advantageous effects

Novel kitchen paper, the fine and close gentle smooth of feeling in top layer, the inlayer absorbs water and locks the water performance excellence.

The double-layer composite material is adopted to improve the strength, and the hollow layer generated by point-to-point embossing is used for achieving the purpose of water absorption and water locking.

The upper epidermis and the lower top layer of upper strata body paper and lower floor's body paper have different rerum natura: the front surface of the paper is endowed with the characteristic of softness and smoothness on the surface of the paper by 100 percent bleached commodity short fibers, so that the use body feeling is improved; the back surface takes the bleached commodity long fiber as a framework, and the high-yield mechanical pulp has the characteristics of high bulk and larger specific surface area, so that a better water absorption and water locking function is brought to paper sheets, and the prepared paper sheets cannot cause back seepage to pollute hands under the action of gravity wiping. In addition, the compact outer surface layer formed by 100 percent of short fibers is not easy to fluff and shed powder, and the secondary pollution of the wiped object is avoided.

The liquid absorption amount of paper is related to the microporous structure of finished paper, and microporous structure is more, just can promote the liquid absorption amount under the capillary action, compares with chemical pulp, and high yield mechanical pulp is owing to kept most lignin, and the fibre is bigger stiff and more, has the characteristic of high bulk, and its more tiny fiber content brings the great specific surface area in fibre surface. Bleached softwood fibers are long and tough and serve as fiber network backbones. The structure endows the paper with better liquid absorption amount, brings better water absorption and locking functions to the paper, and the prepared paper cannot cause back seepage to pollute hands under the action of gravity wiping.

The high-yield mechanical pulp is better environment-friendly green and environment-friendly paper pulp due to lower pollution load in the production process. The yield is generally between 80 percent and 90 percent, the utilization rate of the raw materials is improved, and the production cost of the fiber raw materials is reduced.

The bleached hardwood chemical pulp with the concentration of 100 percent is used as an upper surface layer (surface layer) and is in direct contact with consumers, and the fiber length and the thickness of the bleached hardwood chemical pulp are lower than those of softwood chemical pulp, so that the surface of finished paper has better smoothness and softness, and the use experience is improved. In addition, the compact outer surface layer formed by 100% of short fibers has high surface strength, prevents hair and powder falling phenomena, and reduces the secondary pollution on the surface of an object in the wiping process.

The high-yield mechanical pulp is applied to the inner surface of paper sheets to form a plurality of micropore structures. Under the action of gravity wiping, water which cannot be absorbed by the hollow water-absorbing and water-locking layer generated by point-to-point embossing is absorbed by the inner surface of the paper. Meanwhile, on the outer surface, the liquid is prevented from back-permeating under the combined action of a compact surface layer formed by bleaching hardwood chemical pulp, and hands are not polluted.
