Abstract
A household paper or paper for hygiene (toilet paper 1) consists of at least one, preferably two to four, layers (2, 3, 4) of tissue paper, wherein the paper is provided with an embossment (5, 5') in particular for adhesion of the layers. The paper (toilet paper 1) is after-calendered subsequent to its embossment and optional adhesion of the layers.
Description
2 1 88a ~ 9 Wo 95/29294 A ._I/IL. 1483 uu:,~;s~ D PAPFR OR PAPER FOR HYGIENE AND PRO~A~c~A FOR rN
ITS ~U~ S AND ~lluc~ ITS VOL~IME WT~N PAARFn The invention relate5 to a hn-lqPhA,lrl paper or paper for hygiene according to the ~L~ ' le of Claim l and to a process for increasing the softness and reducing the volume of such papers when packed.
It is known to produce hmlc~Ahnl~ or hygiene papers ~rom at lcast one, preferably two to four layers of tissue paper, the product being provided with an: `- In the case of single- and multi-layered papers, this: necessitates surface texturing which makes the paper ~ ntly soft. In t_e case of a multi-layered hnlcPhnltl or hygiene paper, the c ' L also serves to stick the individual layers of tissue paper together.
An example of such a hA~ n~l or hygiene paper and its production is given in DE 3g 42 536 C2.
The properties for use of hnllqAhnl~1 or hygiene papers have to meet various re iuirements . For exahple, hygiene papers such as toilet paper, handkerc_iefs or cosmetic cloths on the one hand have to be as soft as possible but on the other hand have to have a certain degree of strength. For e ~A and ecological reasons, which are becoming increasingly; La~1L nowadays, - goods in general and .,u..~.~u~.~,.Lly also household or hygiene papers generally have to be p~rl-:~hl ~ as compactly as pnqFihl~ to save plr~j;nj material as well as L-a...,~u-~dtion, storage and shelf space in the places of sale. The saving in p~rl-~7;nj material alqo allows rl;qrn~l costs imposed on --nllf~r~-lrer5 of such papers owing to the laws governing waste ~:n~ ~ ~keyword: "green point") to be reduced.
On the basis of the problems posed, the object of the invention is to provide a ho~q-Ahn~tl or hygiene paper in such a way that it has a smaller packed volume with increased so~L,.e ~ and virtually qA~l strength. In te~ms of the process, the so~L~e2.s of SUA~STITUTE SHEET (RU~E 26) 880~
wo95/29294 - 22l r~ . 1483 household or hygiene paper is to be increased and its packed volume to be reduced by the invention.
,, This obj ect is achieved by the f eatures mentioned in the characterising part of claim 1 or claim 3. It has been found that owing to the indicated after-calendering of the paper after the ~ ' thereof and optionally sticking of layers with practically insignificant losses of strength, on the one hand a clear increase in softness and, on the other hand, a clear r~ rt;rn in the ~hirknPc~ of the paper can be achieved. The jump in softness is manifested in that a toilet paper of average SvrL.-e6~ ~uLuduced in the conventional way acquires softness in~ to that of a cosmetic cloth merely due to the ~fter-calendering. With regard to the r~ rtirn in volume, the roll volume, for example, of toilet paper can be reduced by up to 50~ with the same number of sheets and therefore same length of paper, owing to moderate calenderinq. This means that up to twice as much toilet paper can be placed in a large packing with the same roll and theref ore packing volume .
Claims 2 and 4 give a.lval-L~uu:. ranges of values for the linear pressure of the calendering rollers. Such linear yLC:S~ULt: values can already be achieved owing to the inherent weight of conventional r~l~n~l~ring rollers. To achieve the higher linear ~UL~U~e values within the Gr~r;fiP~ range, it is cllff;ri~nt to load the calendering rollers with EJLeS:~ULt: cylinders having a moderate cylinder ~JL'~:~"UL~ below 1 bar.
Further features, details and advantages of the invention can be inferred from the following description in which an ~ 'i L
is described in detail with reference to the ~ nying drawing .
The drawing shows schematically the cu~.:,LLu~;~ion of a toilet paper according to the invention and the after-calendering thereof .
SUBSIITUTE SUEET (RULE 26) WO 95/29294 P_1/~ 1483 -As shown in the drawing, a toilet paper 1 according to the invention consists of three layers 2, 3, 4 of tissue paper having a weight per unit area of about 15 g/m2. The upper layer 2 on the one hand and the two lower layers 3, 4 on the other hand are each provided with mound-like: LD 5, 5' which each extend concavely inwardly from the upper side 6 and lower side 7 of the paper. Ariht~qinn between the layers 3, 4 on the one hand and the layer 2 on the other hand is achieved at the peaks 8 of the ' ~ 5 ' of the underside of the paper 7 owing to the ' - in~ yr~~DuLe.
The mutual offset of the mound-like ~ _ ts 5, 5' in the layers 2 or 3 and 4 do not produce ro~l~h~nir~ mounds from the upper side 6 or underside 7 of the paper, 80 such a toilet paper 1 is already relatively soft. As also shown in the enlarged detail in the Al -nying drawing, a traditionally ~,L~du~;ed toilet paper 1 of this type has a relatively great 1 h i ~-lrn~cc owing to the bulking by the - - Ls S, 5 ' .
It is accordingly ~ u~osed according to the invention that a toilet paper 1 produced traditionally up to this production staqe be passed through a pair of calendering rollers g with an upper pressing roller 10 and a lower opposing roller 11 in order to subject it to after-calendering. The pair of calendering rollers 9 is ~ t~ly convPn~i- nAl in ~.ul~DLLueLion and therefore requires no further explanation. It should merely be jt~ntcl that t_e pressing roller lO operates under the load of its inherent weight or is loaded against the opposing roller 11 ~y the two yLeSDuLè cylinders 12, 13 with relatively low cylinder s p of less than 1 bar. The linear pressure values at~ ~inAhlf~ are therefore in the range of 10 to 30 N/cm approx.
The DLLe..yU- of the toilet paper 1 is virtually unaffected by this after-calendering, but its ~OLL.Iess is increased and its th~f-kntqq Sû considerably reduced that considerably more sheets of toilet paper 15 pass onto a roll of toilet paper 14 of ~-hAn~ DL ....~ 7i D.
~UESTITUTE SHEET (~ULE 26) _ . , . , . , _ _ _ _ W095/29294 ;~ 1 880 ~ 9 /~1 The following table quantitatively ~' ~ LLc.t.es these ~ualitative statements. The mea:,uL ~ c were taken on conventional commercial toilet paper produced by the ;IrPl i r~ntS . The toilet paper products "BESS Perfect" (2-layered~, "BESS Exclusiv" (3-layered) and "BESS First Class" (4-layered) were used. These toilet papers were investigated without calendering and subse~u~..L to after-calendering with a linear ~L~s~.uLa of about 20 N/cm. The breaking strength was measured dry in the longitudinal and LLO.~I:.V- L~e direction of the machine and the relationship between number o~ sheets and diameter when the toilet paper was wound onto conventional rollers was measured with comparable winding tensions. The softness was evaluated by a conventional panel test.
The - ~ L~ led to the results ; l ~rl in the f ollowing table .
