Description

Cellulosic fibrous web with embossed pattern
FIELD OF THE INVENTION
The present invention relates to a kind of cellulosic fibrous web, especially have the cellulosic fibrous web of embossed pattern.Described embossed pattern makes the appearance looks elegant of cellulosic fibrous web, and has bulkiness.
The background of invention
Cellulosic fibrous web for example tissue products almost uses in daily life constantly.Toilet paper, paper handkerchief and face tissue are exactly the example of the cellulosic fibrous web that uses in household and the industry.Though the cellulosic fibrous web of this maintenance base material form is accepted by the consumer for a long time, still the cellulosic fibrous web of demand appearance looks elegant.The cellulosic fibrous web of appearance looks elegant gives the consumer impression with the high product quality.Simultaneously, also need to make cellulosic fibrous web fluffy.Consider high quality of products demand bulkiness from consumer's position, relevant with flexibility and absorbability.
Many methods have been attempted to improve the aesthetic property and the bulkiness of cellulosic fibrous web outward appearance.For example, it is also fluffy that embossed pattern just can make the appearance looks elegant of cellulosic fibrous web usually.Many effort all relate to the cellulosic fibrous web embossing.For example, the United States Patent (USP) № 5562805 that authorized people such as Kamps on October 8th, 1996 has just disclosed the manufacture method of the soft cotton paper of high fluffy.This cotton paper is with tiny embossed pattern embossing, to improve bulkiness and to make the loss of strength minimum.This tiny embossed pattern contains at least about 15/centimetre 2(100 inches 2) the independent embossing units that overlaps of going here and there mutually again.
The United States Patent (USP) № 5300347 that authorized people such as Underhill on April 5th, 1994 has disclosed a kind of embossing face tissue.This uniform embossing face tissue has continuously or approaching discrete interval embossed pattern.The line of embossed pattern makes and is crushed on the not embossed portion that line surrounds and divides quite fluffy.Per inch 2Cotton paper has 1-40 unique not embossed regions approximately.
The United States Patent (USP) № 4759967 that authorized people such as Bauernfeind on July 26th, 1988 has disclosed a kind of embossing method and goods.Majority, preferred basic all background embossing all have main shaft and secondary axes.Main shaft is basic parallel with the CD of base material.It has also disclosed the background embossed pattern of basic covering substrates and the layout of additional spacer.The layout of described additional spacer is formed by the central plane of not embossing.
The U.S. design patent № 371910 that authorizes people's such as Rothwell U.S. design patent № 362967 October 10 nineteen ninety-five and authorized people such as Schultz on July 23rd, 1996 has disclosed the paper products of embossing.The paper products of these embossing have coarse relatively embossing and the bigger not embossed regions of embossed pattern inner area.
The operating period of consumer demand product when keeping the sheet material bulkiness is long, sheet material more on the given diameter roller or in the intended size case thus.A kind of method that increases sheet material quantity on the given diameter roller or in the intended size case is the nested property maximum that makes embossed sheet.But, just be difficult to nestedly each other if the embossing on the sheet material is tiny, it is nested to hinder sheet material to carry out each other thus.On the other hand, compare with tiny embossing, big embossing is easier to nested each other.But when sheet material gathered into folds or roll, big embossing was just caved in easily, loses bulkiness thus.
In addition, also require to make the appearance looks elegant of net by shirtsleeve operation.A kind of method is to arrange embossing, forms desired pattern, for example arranges by keeping not the predetermined area of embossing cellulosic fibrous web, forms designed pattern by embossing plane not thus.Keeping not, the mass part embossing fibre of cellulosic fibrous web just can make the outward appearance of net more attractive in appearance.But the embossing area is not too much on the net for cellulose fibre, when reeling on the roller or laminating in case, will damage the nested property of sheet material.This will form for example wrinkling and/or wrinkle on the product surface in the roller goods or the case of packing into.
Therefore,, outward appearance not only fluffy but also cellulosic fibrous web attractive in appearance with regard to demand; Product also demand to be suitable for the operating period long; Also demand reduces the lip-deep wrinkling and/or wrinkle of end article.
The general introduction of invention
The present invention relates to have the cellulosic fibrous web of embossed pattern.This embossed pattern comprises repeat patterns.A kind of repeat patterns comprises many discrete special areas and the background matrix that is formed by many separative elements.Repeat patterns forms by the embossing cellulosic fibrous web.The density of separative element is 40-90/inch in the background matrix 2Described this separative element by background matrix of discrete tape base distinguishingly surrounds and forms.The size in a discrete special area is equivalent to from 4-90 separative element of background matrix deduction.The gross area in an interior special area of dispersing of repeat patterns accounts for the 3-35% of a repeat patterns area.
