Description
Invention field
The present invention relates to tissue paper, particularly face tissue and disposable handkerchief.A kind of three layers of tissue paper with embossing intermediate layer are provided in a preferred embodiment.
Background of invention
Paper web or paper are referred to as tissue paper or tissue webs or paper sometimes, or are referred to as tissue paper here, in modern society extensive use are arranged.Described article are the commodity of a large amount of supplies as face tissue and toilet paper, and these article all are called tissue paper here.For a long time, people think that always the important physical characteristic of these products is its intensity and slide calliper rule thickness, its pliability and smoothness, its absorbability and its resistance to picking.Various research-and-development activitys concentrate on one of them that improve these characteristics under the not serious situation that influences other performance always, or concentrate on and improve two or three described characteristics simultaneously.
Pliability and smoothness are that the consumer holds a certain products, it is rubbed mutually with skin, or the user rub the sense of touch of being experienced in hand.This sense of touch is that the combination of some physical properties provides.Those skilled in the art it has been generally acknowledged that, one of prior physical property relevant with pliability and smoothness is the surface structure of the tissue paper of the described tissue paper product use of preparation, and its available physiology surface flatness (PSS) parameter characterizes better, as US 5,855,738 is described.The slide calliper rule thickness of thin-paged paper products also is very important for consumer's sense of touch.
Intensity is that product is kept physical integrity and tear-resistant under service condition, anti-broken and anti-ability of tearing up.
Absorbability is measuring of product the absorption liquid scale of construction, the particularly aqueous solution or aqueous dispersion ability.Total absorbability that the consumer feels is considered to usually: the tissue paper of given quality absorbs the total amount of liquid and the speed that given quality tissue paper absorbs liquid when saturated.
Resistance to picking is a fiber product, with and form the ability that bonds together when paper web comprises hygrometric state under service condition.In other words, resistance to picking is high more, paper web fall the hair tendency will be low more.
WO97/44528 discloses a kind of multi-layered tissue paper goods with high-absorbable.Embodiment 4 discloses a kind of goods, and one of them is figuratum to have between the layer of the no textured structure that is placed on two essentially no decorative patterns of certain textured structure relatively.
EP 0 264 676 discloses the preparation method that a kind of multi-layered tissue paper is opened.Embodiment 3 discloses three laminates that a kind of paper that forms by wet method is made, and wherein the internal layer paper web is to be 18g/m by weight
2Cruddy paper form, and outer paper web is to be 14g/m by weight
2The press polish paper handled form.With nozzle cellulose ether binder is coated on these layers, they are bonded together.
US 5,855, and 738 disclose a kind of method for preparing smooth tissue paper, and this method contains the press polish step.
Thick relatively disposable paper products, promptly paper handkerchief and face tissue are known.Procter ﹠amp for example; The Tempo that Gamble company sells
TM, its slide calliper rule thickness is about 0.3mm.High slide calliper rule degree transmits the notion of high dry strength and high wet strength to the consumer.High wet strength is also referred to as wet burst strength, can prevent from especially to tear or break, and tear or break can cause the user hand by mucus or other humoral pollution.
Thicker disposable paper products also is known, generally as kitchen-towel, for example Procter ﹠amp; The Bounty that Gamble company sells
TM, its slide calliper rule thickness is about 0.7mm, and wet burst strength is greater than 200g.Yet the slide calliper rule thickness of this kitchen-towel depends on that on sizable degree this embossing causes surface texturisation coarse in whole lip-deep embossing, and suitable smooth wipe surfaces can not be provided when blowing one's nose
The goods that other has the broken intensity of high humidity and generally has relative caliper are those products that adopt the Tad method to produce.But, on the paper machine of routine, there is not this Tad equipment, therefore preparing such equipment just means the sizable investment of needs.
In theory, the wet strength and the slide calliper rule thickness of goods can be increased, smooth outer surface can be kept thus by the number of plies being increased to 5,6 layers or more multi-layered (replace embossing etc.).But this method is very expensive, and will obtain stiff goods, therefore can destroy sense of touch.
Attempting providing very smooth when surperficial, the method with the tissue paper press polish is normally adopted in this area.But press polish means it is with slide calliper rule thickness and the compromise method (for example US 5,855, and 738 is described) of pliability for slickness all the time.
Consider prior art, still have the demand to thin-paged paper products here, particularly to the demand of face tissue, described goods are characterised in that:
-be combined with best intensity, i.e. wet burst strength, absorbability and resistance to picking
-sense of touch of desirable pliability, smoothness and thickness also is provided
-be that cost is effective for preparation, and preferably can on the paper machine of routine, prepare
-optional the skin-care function that provides
Summary of the invention
The present invention relates to a kind of tissue paper, particularly face tissue and disposable handkerchief.Claimed and tissue paper that be described contains two-layer at least; it is characterized in that physiology surface flatness parameter that tissue paper has is less than 700 microns; be preferably the 650-50 micron; more preferably 650 microns-300 microns; and every layer slide calliper rule thickness is greater than 0.09mm; be preferably 0.09mm-0.5mm, more preferably 0.1mm-0.2mm.In a preferred embodiment, a kind of three layers of tissue paper are provided with embossing intermediate layer.The invention still further relates to claimed and method that be described.Detailed Description Of The Invention
