Description

具有突出洗剂沉积的薄页纸 Tissue paper having a lotion deposited projection

发明领域 Field of the Invention

本发明涉及薄页纸和由薄页纸制成的产品。 The present invention relates to tissue paper and tissue paper products made from. 更具体地讲,本发明涉及一种包含洗剂沉积的薄纸,所述洗剂沉积的高度显著高于所述薄纸表面的平均平面。 More particularly, the present invention relates to a tissue comprising a lotion deposited, the height of lotion deposited significantly higher than the average plane of the tissue surface.

发明背景 BACKGROUND OF THE INVENTION

薄页纸有时称为纸幅或纸张、薄纸、薄纸层、复层纸或薄纸幅,以及由其制成的产品,例如纸帕、厨房用纸巾或浴室用薄纸、卫生纸或面巾 Sometimes called tissue paper product or paper web, tissue, tissue layer, or the double layer of paper tissue webs, and made therefrom, such as paper Pa, kitchen bathroom tissue or paper towels, toilet paper or towel

薄页纸通常用以下步骤制造:将润湿状态的纤维素纤维在筛网上成层,添加各种添加剂或其他成分,随后烘干。 The tissue is generally manufactured by the following procedure: wet state the layer of cellulose fibers into a mesh, various additives or other ingredients, followed by drying. 在上述制纸步骤之前、期间或之后的其它工序旨在赋予薄纸所期望的特性。 In the above paper making step before, during or after other steps intended to impart desired properties tissue. 转换加工步骤的目的在于将薄页纸加工成成品。 Objective step is converting the tissue sheet into a product.

由薄页纸制成的产品可通过多层薄页纸(也称为层片)的组合来制备,或可包含一个薄页纸层(单层产品)。 Tissue paper products made from multi-ply tissue may (also called plies) a combination preparation, or may comprise a thin paper layer (single product) through. 那些层片可按多种方式进行组合并结合在一起以形成成品,例如通过多层结构的压花或/和通过胶粘。 Those plies can be combined in various ways and bonded together to form the finished, e.g., by embossing a multilayer structure or / and by gluing. 本文中将成品称为薄纸制品。 It referred to herein finished tissue products. 成品由不止一个层片制成,所述层片具有方向朝内的内薄纸(或层片)表面和两个方向朝外的外表面。 The finished sheet made by more than one layer, said layer having an outer surface of the sheet outwardly toward the inner direction of the tissue (or ply) surfaces and two directions.

长期以来一直认为,这些薄页纸的重要物理属性是它们的强度和厚度/膨松度、它们的柔软性和光滑度以及它们的吸收性。 It has long been believed that these important physical properties of the tissue are their strength and thickness / bulkiness, their softness and smoothness, and their absorbency. 柔软性和光滑度涉及当将某一特定产品握在手中、用它擦拭皮肤或将它在手中揉皱时使用者能够感受到的触感。 It relates to softness and smoothness when in the hands of a particular product, and wipe the skin or crumpling it in the hands of the user can feel the tactile sensation.

相对较厚但较软的一次性纸制品,即纸帕形式,已为人们所熟知。 However, a relatively thick soft disposable paper products, i.e., Pa in the form of paper, has been well known. 例如,Procter & Gamble Company出售的Tempo™是感觉厚而软的多层纸制品,其厚度为约0. 3mm。 For example, Procter & Gamble Company Tempo ™ sold by feeling soft, thick layers of paper product having a thickness of about 0. 3mm. 厚度大会给使用者一种干、湿强度都很高的感觉。 A dry thickness of the Assembly to a user, the feeling is high wet strength. 高的湿强度,也称为湿破裂强度,尤其能够防止撕开或破裂,对于纸帕而言,这种撕开或破裂又会导致粘液或其它体液弄脏使用者的手。 High wet strength, also referred to as wet burst strength, in particular, can prevent tearing or rupture, for the purposes of the paper Pa, which will lead to tearing or rupture of mucus or other bodily fluids soiling the user's hand.

增强薄纸表面光滑度的常用方法是对材料进行压光。 The method commonly used tissue paper surface smoothness reinforcing material is calendered. 改进薄纸制品如手帕的使用者所觉察的光滑感的另一种方法是在造纸阶段中和/或转换加工阶段中为薄页纸组合物补充一些添加剂。 Another method for tissue products of smoothness perceived by the user as a handkerchief improvement in papermaking stage and / or the converting phase additive is to add some tissue paper composition. 那些添加剂可具有使薄页纸光滑的效果,在某种程度上让使用者感觉它更柔软或光滑。 Those additives can have the effect that the smooth tissue paper, in a way that it allows users to feel more soft or smooth. 可供选择地或此外,某些添加剂对触摸或使用该薄纸制品的使用者皮肤有影响,如使皮肤光滑、使皮肤水合。 Alternatively or in addition, the use of certain additives or touch the user's skin affect tissue products, such as smooth skin, the skin hydration. 这后一种效果通常通过在使用过程中添加剂部分转移到皮肤上来获得,从而在薄纸制品与皮肤之间接触期过后,延长添加剂在皮肤上的效果。 This latter effect is usually through a partial transfer of the additives during use to get to the skin, so that after the contact period between the article and the skin tissue, prolonged effect of the additives on the skin.

光滑洗剂通常是疏水性的或包含疏水化合物。 Lotions are usually smooth hydrophobic or comprises a hydrophobic compound. 洗剂存在于薄页纸表面 Lotion present in the surface of the tissue

上可对薄页纸的性质具有不利影响:首先,亲水薄纸表面被疏水洗剂遮盖可降低薄纸的吸收性或吸收速度。 May adversely affect on the tissue properties: First, the hydrophilic tissue surface is covered by a hydrophobic lotion can reduce the absorbency or absorption rate of the tissue. 这为使用者呈现了不可取的效果。 It presents the user with undesirable results. 例如,对于纸帕,有洗剂的薄页纸要比无洗剂的花更长时间才能吸收鼻粘液。 For example, for a paper handkerchief, tissue paper than with a lotion-free lotion take longer to absorb nasal mucus. 其次,洗剂可从薄纸表面移至薄页纸结构中从而使薄页纸更不亲水, 并使在表面上有更少的洗剂可用于将光滑有益效果递送至皮肤。 Second, the lotion can be moved from the tissue structure so that the surface of the tissue paper tissue less hydrophilic, and has less lotion on the surface can be used to smooth delivery of the beneficial effects to the skin. 解决洗剂随时间预期迁移的传统方式是使用相对大量的洗剂,以确保即使是在长期存储后薄纸表面上也有一基重可用的洗剂。 Traditional approaches to solving the expected migration of the lotion over time is to use a relatively large amount of lotion to ensure that even after long term storage on the surface of the tissue paper has a basis weight of lotion available. 这继而在刚生产的薄页纸上产生过量的洗剂,从而在使用期间引起无益的油腻感(并且还更进一步降低薄页纸的吸收性)。 This in turn generates excess lotion just produced thin sheets of paper, thereby causing useless greasy feeling during use (and also to further reduce the absorbency of the tissue paper). 第三,使用期间涂敷在纤维上的洗剂不容易被薄纸释放,因此较少可转移到使用者皮肤上。 Third, a lotion coating on the fibers during use of the tissue is not easily released, and therefore less can be transferred to the user's skin. 此外,由于洗剂原料的成本相对较高,在薄纸上使用减少量的洗剂还有经济上的优点。 Further, since the relatively high cost of the lotion raw materials, as well as the use of a lotion economic advantage in reducing the amount of tissue.

因此,需要提供一种薄页纸,在所述薄纸的表面处显示具有离散沉积形式的相对大量的可用洗剂,所述洗剂从薄纸表面突出显著的高度。 Therefore, desirable to provide a tissue paper, a display having a relatively large number of available discrete deposits of lotion at the surface form of the tissue paper, the lotion projecting significant height from the surface of the tissue.

此外,还需要改善薄纸的光滑有益效果、改善薄页纸的吸收性,并且改善洗剂向使用者皮肤的可转移性,同时一种改善不会对另一种改善造成损害。 In addition, the need to improve the smoothness of the tissue beneficial effects, improving the absorbent tissue paper, the lotion to the skin of the user and to improve the transferability, and an improved without causing harm to another improvement. 发明概述 SUMMARY OF THE INVENTION

为了解决与现有技术有关的这些问题,本发明提供了一种具有第一和第二相对表面的薄页纸,其中所述薄纸在所述薄页纸的至少一个表面上包含洗剂。 To solve these problems associated with the prior art, the present invention provides tissue paper having first and second opposing surfaces, wherein the tissue comprises a lotion on the tissue paper at least one surface. 洗剂以基本离散的突出沉积存在于第一表面上,其中所述薄页纸 Projecting substantially discrete lotion deposited on the first surface is present, wherein said tissue paper
