Above-mentioned have varying strength paper for daily use 100 by following method obtain.
One, by using the softening agent of different proportion to realize in overlay paper 10 and core paper 20
Softening agent is the chemical drug that a class can improve ply of paper pliability, but this kind of chemical drug inevitably reduces the intensity of ply of paper usually.When manufacturing paper with pulp this core paper 20, using softening agent more more than overlay paper 10, making core paper 20 have better pliability.Whether overlay paper 10 will use the size of softening agent and use amount thereof to decide according to the actual requirements, and prerequisite is the height of the strength ratio core paper 20 of the final overlay paper 10 formed.Possessing the overlay paper 10 of this feature, core paper 20 arranges in pairs or groups the paper for daily use 100 together formed, and can meet the intensity of consumer for paper for daily use 100 and the demand of feel simultaneously.
Two, by using the long fibre of different proportion to realize in overlay paper 10 and core paper 20
Long fibre reduces ply of paper pliability while raising ply of paper intensity, and short fiber reduces the intensity of ply of paper in the pliability improving ply of paper simultaneously.Manufacture paper with pulp in process at ply of paper, utilize long fibre and short fiber characteristic separately, in conjunction with the demand of consumer to paper for daily use intensity and feel, the long fibre ratio in overlay paper 10 is relatively high, to ensure higher intensity; Short fiber ratio in core paper 20 is relatively high to provide certain pliability.Therefore, by the paper for daily use 100 of multilayer formed of arranging in pairs or groups like this, the demand of consumer for intensity and feel can be met simultaneously.
Three, by using different cornerites to realize when manufacturing paper with pulp in overlay paper 10 and core paper 20
Paper for daily use, in the process of manufacturing paper with pulp, peels off from drying cylinder by the ply of paper of creping doctor by shaping, reaches wrinkling effect simultaneously.The intensity of wadding can have been changed by changing cornerite.Cornerite refers to the angle between the tangent line at dryer surface contact scraper place and the surface of wing.Cornerite is larger, and the ply of paper intensity of manufacturing paper with pulp is higher, otherwise cornerite is less, and the ply of paper intensity of manufacturing paper with pulp is less, and also namely the difference of cornerite can cause the change of ply of paper intensity.When manufacturing paper with pulp overlay paper 10, using the cornerite larger than core paper 20, making the intensity of overlay paper 10 higher.On the contrary, when manufacturing paper with pulp core paper 20, using the cornerite lower than overlay paper 10, making core paper 20 more soft than overlay paper 10.Therefore, the paper for daily use 100 formed by the multi-ply paper of arranging in pairs or groups like this, can meet the demand of consumer for intensity and feel simultaneously.
Four, by using the different defibrination time when manufacturing paper with pulp overlay paper 10 and core paper 20 or adopting different defibrination power to realize
At the defibrination initial stage, use the suitable defibrination time, the ply of paper intensity that gained slurry manufactures paper with pulp out is higher, but defibrination overlong time, and ply of paper intensity can decline on the contrary; Or defibrination power is larger, the ply of paper intensity that gained slurry manufactures paper with pulp out is also larger.When manufacturing paper with pulp overlay paper 10, use the defibrination time better than core paper 20 of manufacturing paper with pulp or higher defibrination power, thus make the intensity of the strength ratio core paper 20 of overlay paper 10 high.Therefore, the paper for daily use formed by the multi-ply paper of arranging in pairs or groups like this, can meet the demand of consumer for intensity and feel simultaneously.
Five, by using different chemical drug additions to realize when manufacturing paper with pulp overlay paper 10 and core paper 20
In the process that ply of paper is manufactured paper with pulp, use some chemical drug such as drying strengthening agent, wet strength agent, certain class biology enzyme etc. can improve the intensity of ply of paper.When manufacturing paper with pulp overlay paper 10, according to the actual requirements, the chemical drug being improved ply of paper intensity of consumption higher than core paper 20 can be used, thus make overlay paper 10 have higher intensity.Therefore, the paper for daily use 100 formed by the multi-ply paper of arranging in pairs or groups like this, can meet the demand of consumer for intensity and feel simultaneously.
Six, by using different kinds of fibers to realize when manufacturing paper with pulp overlay paper 10 and core paper 20
The kinds of fibers that paper for daily use uses mainly comprises Original Pulp fiber and primary non-wood pulp cellulose.Original Pulp fiber refers to the paper pulp that natural chip steaming extracting fiber is made, and has dividing of needle, broad-leaved Original Pulp.And primary non-wood pulp cellulose refers to the paper pulp that the rhizome of natural plants is made, mainly contain straw pulp fiber, cane syrup fiber and reed pulp fiber.The more primary non-wood pulp cellulose of paper for daily use paper that Original Pulp is manufactured paper with pulp manufactures paper with pulp that intensity is higher and pliability is better.When manufacturing paper with pulp overlay paper 10, adopting the Original Pulp fiber of higher proportion, adopting the primary non-wood pulp cellulose of higher proportion when manufacturing paper with pulp overlay paper 10, thus making overlay paper 10 have higher intensity.Therefore, the paper for daily use 100 formed by the multi-ply paper of arranging in pairs or groups like this, can meet the demand of consumer for intensity and feel simultaneously.
Below only illustratively list feasible several implementation methods, combination that can be suitable according to working condition in actual production, or change other factors, to obtain the paper for daily use with above-mentioned feature.
Paper for daily use 100 of the present invention, by improving the material component of overlay paper 10 and core paper 20, the intensity of overlay paper 10 is higher, and determining whole paper for daily use 100 has higher intensity, and though core paper 20 intensity is lower than overlay paper 10, also play certain strengthened effect.Utilize overlay paper 10 and the characteristic of core paper 20 in reasonable combination thus, make described paper for daily use 100 entirety have higher intensity and good pliability, not easily broken paper in rewinding process, be easy to folding forming and printing, and clean surface, do not fall bits, feel requirement can be met again.
In addition, when paper for daily use 100 of the present invention is as reel type paper for daily use, the kinds of fibers different from core paper 20 due to upper and lower overlay paper 10 and the difference of fiber architecture, cause the coefficient of friction between overlay paper 10 from core paper 20 different, reel type paper for daily use each fault rupture line in unwind process can reliably be overlapped, be convenient to tear fracture toilet paper, solve the problem that geosutures do not overlap.
