Abstract

Disclosed are liquid impregnated sheets containing a combination of split-fibres and/or meltblown fibres with regular fibres of thermoplastic polymers. The sheets can be monolayers or multilayers with non-wovens of split-fibres on the outer portions of the multilayered sheets.
The sheets possess good storage and release characteristics for a liquid and can be used as cleansing sheets for personal care.

Description

    Field of the Invention
  • This application relates to spunlaced fabrics and to multilayered sheets and to a process for their production, wherein the sheet is intended for use as a liquid impregnated wipe, preferably for personal care.
  • Background of the Invention
  • Non-wovens made from fibres with very fine denier are known. One method for preparing such non-woven products comprises spinning of multicomponent fibres of incompatible polymers, formation of the non-woven in a manner known per se and subsequently splitting the multicomponent fibres into their single components by the action of hydroentanglement. Those non-wovens are disclosed for example in US-A-5,970,583 and US-A-6,465,095.
  • EP-A-864,006 discloses a non-woven made from micro fibres of very fine denier. These are produced from very fine splittable fibres which are made by melt blowing of at least one hydrophilic or hydrophilically treated polymer. Also disclosed is production of laminated products by combination of these non-wovens with other layers. These products are proposed as single use products (disposal).
  • Other non-wovens made from split fibres and their combinations with other non-wovens or films are disclosed in WO-A-96/41,041 and WO-A-97/21,862, The split fibre non-wovens are characterised by the presence of two different fibre types from incompatible polymers, one thereof being hydrophilic. The non-wovens can be used in different fields, for example in diapers or in protective clothing.
  • Multilayered textile sheet made from microfibres different from split fibres are also known. Some of these combinations are excellent cleansing wipes.
  • EP-A-569,860 discloses a mufti-layered non-woven which is a combination of spunbond layers with a layer of meltblown microfibres inbetween. The spunbond layers are made of thermobonded thermoplastic filaments and contain a nucleating agent. The laminates are characterised by an improved strength and are used as fabrics for working cloth or as components for diapers.
  • EP-A-423,619 discloses cleansing wipes with good cleansing properties and excellent retention for aqueous liquids. The wipes comprise a reinforcement layer, typically a spunbond, which contains synthetic and natural staple fibres. At the surface of these wipes the staple fibre combinations form sections with different area densities.
  • EP-A-357,496 discloses a cleansing wipe made of a non-woven. This consists of a combination of polymer microfibres and wood pulp or cellulosic fibres and is impregnated with a surface active agent. The wipe possesses an absorption capacity of 5-15 g liquid per g substrate.
  • Another cleansing wipe with high liquid absorption capacity is disclosed in EP-A-80,383. This product easily releases stored liquid and is a non-woven comprising thermobonded meltblown fibres. 1-40% of the product surface are openings.
  • DE 199 17 275 B4 discloses a non-woven cleansing wipe made from micro staple-fibres derived from multicomponent split-fibres from at least two different polymers and from absorbent secondary staple fibres made from the viscose spinning process or the lyocell spinning process. Besides a high abrasion resistance and high absorption volume for abrased dirt the cleansing wipe has a good cleansing activity and a good textile feel.
  • DE 199 03 903 A1 discloses a three-layered wipe for cosmetic applications. The wipe consists of a central layer and two cover layers which consist of split fibres with a fibre diameter of less than 10 µm. The wipe has a high effectiveness and a small volume can be washed and reused and can be used without pilling. For the cover layers combinations of polyester and polyamide are disclosed. The central layer can also consist of these fibre combinations, optionally with added viscose fibres or can consist of viscose fibres only. The wipes are designed for dry application.
  • Liquid impregnated wipes for personal care must meet a combination of properties which are difficult to obtain. On the one hand such wipes should retain the liquid as long and as homogeneous as possible during storage without any leakage/sedimentation from lotion into the storage box. On the other hand when used the wipe should transfer a sufficient amount of liquid to the skin of the user.
  • Other requirements are softness and bulkiness of the wipe and sufficient mechanical properties, such as a sufficient strength.
  • In addition the materials from which the wipes are made should be inexpensive and/or the manufacturing process of said wipes should be simple to minimize manufacturing costs.
  • Also the amount of lotion necessary for an intended use should be as small as possible. Thus losses during storage or retention of lotion during use should be also as small as possible.
  • Personal cleansing wipes, particularly baby wipes, are made using a range of nonwoven technologies. Typically synthetic fibres such as polyester or polypropylene are combined with cellulose fibres such as viscose, lyocell, cotton or wood pulp. Generally the synthetic fibre provides bulk and low cost and the cellulose fibre provides absorbency. The use of cellulose imposes limitations on softness, strength, bulk and cost.
  • Summary of the Invention
  • It is one object of this invention to solve the need for adequate absorbency by substituting for the cellulosic content with microfibres of thermoplastic polymers. This allows for an enhanced mix of fabric properties at reduced base weight, notably an increase in softness, strength, toughness, thickness and opacity.
  • It is another object of this invention to provide wipes with improved storage and release capability for liquid.
  • It is still another object of this invention to provide wipes with high effective absorption and release capacity for liquid consisting essentially of thermoplastic polymers.
  • It is still another object of this invention to provide a personal cleansing wipe as well as a process for its manufacture of comparable weight to existing products, without the use of cellulose fibre, which has superior properties of softness, absorbency, thickness, toughness and opacity. The opportunity also exists to reduce basis weight and achieve a low cost product with superior performance.
  • It is still another object of this invention to provide simple and economically improved manufacturing processes for wipes using thermoplastic polymers only.
  • Further objects of this invention will become apparent from the following description.
  • In one embodiment this invention relates to a multilayered sheet impregnated with a liquid comprising a first non-woven layer consisting essentially of thermoplastic polymer fibres of titre of 0.5 to 10 dtex and at least one second non-woven split-fibre layer of thermoplastic polymers.
  • In another embodiment this invention relates to a multilayered sheet impregnated with a liquid comprising at least five layers, one of said layers being a first non-woven central layer consisting essentially of thermoplastic polymer fibres of titre of 0.5 to 10 dtex, two of said layers consist essentially of meltblown fibres of thermoplastic polymers which layers are located at both sides of the first central non-woven layer and which meltblown layers are covered by non-woven layers consisting essentially of thermoplastic polymer fibres of titre of 0.5 to 10 dtex.
  • In still another embodiment this invention relates to a one-layered sheet impregnated with a liquid which is a spunlaced fabric produced from a fibre web consisting essentially of 20 to 97 % by weight of thermoplastic polymer fibres of titre 0.5 to 10 dtex and of 3 to 80 % by weight of split-fibres of thermoplastic polymers and of 0 to 50 % by weight of meltblown fibres of thermoplastic polymers.
  • Unexpectedly it has been found that by combining split-fibres and optionally meltblown fibres with regular fibres of thermoplastic polymers in a single layer or combining different layers of non-wovens of regular fibres with non-wovens of split-fibres and optionally with layers of meltblown fibres with the split-fibre layers on the outer portions of the multilayered sheets or by combining layers of meltblown fibres sandwiched between layers of regular fibres of thermoplastic materials products are obtained which possess the desired storage and release characteristics for a liquid. Thus liquid impregnated wipes made from thermoplastic polymers with simple manufacturing processes can be prepared.
  • The presence of spfit-fibres and/or meltblown fibres in the sheets of this invention provides a combination of valuable properties of the sheet. Adding split-fibres and/or meltblown fibres to fibres with conventional fineness either in form of separate layers and/or as fibre mixtures in single layers results in increased softness, lintfreeness, opacity, storage and release capability for lotion.
  • Detailed description of the invention
  • The impregnated sheets of this invention can consist of one layer only or are preferably multilayer sheets.
  • The term "first non-woven layer consisting essentially of thermoplastic polymer fibres of titre of 0.5 to 10 dteX' shall mean that said fibres form a major part of the fibres of this layer, for example said fibres are present in an amount of at least 50 % by weight, preferably 80 -100 % by weight of said layer. Besides said fibres microdenier fibres and/or additives typically used in such non-woven layers may be present. Examples thereof are pigments, such as titanium dioxide, optical brighteners, hydrophilic agents, flameproofing agents, antistatic agents, biocidal agents or a combination of two or more thereof.
  • The term "second non-woven split-fibre layer of thermoplastic polymers" shall mean that said split-fibres form a considerable amount of the fibres of this layer, for example said fibres are present in an amount of at least 20 % by weight, preferably 70 -100 % by weight of said layer. Besides said split-fibres regular denier fibres (fibres with titre between 0.5 and 10 dtex) and/or additives typically used in such non-woven layers may be present. Examples thereof are pigments, such as titanium dioxide, optical brighteners, hydrophilic agents, flameproofing agents, antistatic agents, biocidal agents or a combination of two or more thereof.
  • The term "thermoplastic polymer" shall mean all thermoplastic and fibre-forming man-made polymers including thermoplastic elastomers.
  • Very preferred sheets comprise three layers including a central non-woven layer of thermoplastic fibres with denier between 0.5 and 10 dtex or of a mixture of at least 80 % by weight of thermoplastic fibres with denier between 0.5 and 10 dtex and of up to 20 % by weight of split-fibres of thermoplastic polymers and at the surfaces two non-woven split-fibre layers of 100 % by weight of split-fibres of thermoplastic polymers or of a mixture of at least 70 % by weight of split-fibres of thermoplastic fibres and of up to 30 % by weight of fibres of thermoplastic polymers with titre between 0.5 and 10 dtex.
  • A very preferred product of this multilayered sheet consists of three layers, wherein a first non-woven layer is a central non-woven layer which is sandwiched between two non-woven split-fibre layers.
