Abstract

A fusion-bonded polyester resilient fleece suitable for use in footwear has a low density (less than 0.02 g/cm3) and comprises 70-90% relatively coarse (at least 6 decitex) polyester staple fibres and 30-70% polyester melt fibres with a melt temperature not less than 105{C. Anti-bacterial fibres may also be included.

Description

RESTT-TENT FLEECE This invention is concerned with improvements relating in or relating to resilient fleeces, especially for use in cushion pads and the like, eg for the heel end of the top line region of a shoe upper, and in shoe upper linings.
Conventionally, especially in the manufacture of socalled trainers, the top line region of the shoe upper and also the tongue of the shoe upper tend to be filled with a cushioning material, which may be in the region of 10 to 15mm thick. In addition, the upper may be lined with a lining material of similar construction but thinner, eg in the region of 3 to 4mm thick. Conventionally, moreover, such materials-have tended in the past to be closed-cell polyurethane foam materials. While such materials perform satisfactorily at least in the initial periods of wear, because they are closed-cell they do not "breathe" and in addition they may be subject to discolouration and indeed to degradation during the course of wear. It will thus be appreciated that such materials in the longer term do not provide the highest levels of hygiene to the wearer.
It is thus one of the various objects of the present invention to provide a resilient fleece having the resilient properties of a polyurethane foam material, but without the above-stated disadvantages of the foam material.
The invention thus provides, in one of its several aspects, a resilient fleece having a density of less than 0.02g/cm3 (20kg/m3), said material comprising 70-90% by weight polyester fibres and 10 to 30% by weight polyester melt fibres, wherein the polyester fibres have a staple length in the order of 30 to 70mm and a decitex of not less than 6, and wherein the melt fibres have a melt temperature of not less than 105"C, and further wherein the fibres are fusion-bonded.
It has been found that such a material provides a resilience which is generally akin to that of a polyurethane foam material, but which by reason of its construction is breathable and further is resistant to discolouration and degradation in wear.
One particular feature of the resilient fleece in accordance with the invention is the coarseness of the polyester fibres used and in a preferred embodiment such fibres have a decitex of 6.7. In addition, in order to achieve the correct degree of resilience the combination of the component fibres is significant and it has been found that using 25% by weight of the melt fibres the resilient properties afforded by the relatively coarse polyester fibres can be sufficiently retained to give the level of resilience required.
In order further to enhance the hygiene afforded by the resilient fleece in accordance with the invention, furthermore, preferably the fleece contains 10 to 20% by weight anti-bacterial fibres. In one preferred embodiment of the invention, therefore, the resilient fleece comprises 65% by weight polyester fibres, 25% by weight polyester melt fibres and 10% by weight anti-bacterial fibres.
The bacterial fibres are preferably acetate-based.
The melt temperature of the melt fibres should be sufficiently low in order to facilitate the fusion-bonding of the fleece, but not sufficiently low that it will melt during the course of normal shoe making procedures.
Preferably, therefore, the melt temperature is in the order of 110 C.
In one embodiment, which would be suitable eg for cushioning the top line region of the heel end of a shoe, a fleece in accordance with the invention has a thickness of 10 to 15mm and a weight in the order of 165 to 250g/m2. In another embodiment, on the other hand, which is suitable eg for lining shoe uppers, the fleece has a thickness of 3 to 5mm and a weight in the order of 50 to 85g/m2.
The invention also provides, in another of its several aspects, a cushion pad, eg for the heel end of the top line region of a shoe upper, made from a resilient fleece in accordance with the invention as referred to above.
The invention still further provides, in another of the several aspects, a shoe upper lining material made from a resilient fleece in accordance with the invention as referred to above.
Example I Polyester fibres, together with polyester melt fibres and anti-bacterial fibres were blended in the following proportions: 65% by weight polyester fibres 25% by weight polyester melt fibres 10% by weight anti-bacterial fibres.
The polyester melt fibres used are identified by the designation T252, available from Hoechst AG. These fibres have a melt temperature in the order of llO"C, a staple length of 38mm and have a decitex of 2.5.
The anti-bacterial fibres are designated Microsafe AM, also available from Hoechst. ("Microsafe" is a Registered Trade Mark of Hoechst Celanese Corporation.) It is understood that these anti-bacterial fibres are acetatebased. These fibres have a staple length of 38mm and a decitex of 2.
The fibre blend was then subjected to a needling operation which reduced the overall thickness from to 12mm, such that the weight of the fleece thus formed was in order of 200g/m2, giving a density in the order 0.0167g/cm3 (16.7kg/m3).
Following the needling of the fleece as aforesaid, the fleece is then subjected to a stream of hot air at a temperature in the order of 1200C thus to cause the melt fibres to melt and thereby bond the needled fibres in position. It has been found that by using coarse fibres and fusion-bonding them in this way, the resilience of the fleece is established.
Following manufacture of the fleece in the aforementioned manner the fleece was then laminated to a backing layer; in this Example the backing layer was a knitted fabric. Using such a layer the fleece can then effectively be secured through the backing layer to a shoe upper component and thus be lodged in position.
The fleece thus prepared had good resilience and durability and was resistant to discolouration and degradation in wear. A fleece of this type was considered to be suitable for incorporation in the top line region of the heel end of a trainer shoe and also in the upper portion of the shoe tongue.
Whereas in this Example the fleece is laminated to a backing layer, it will be appreciated that the fleece may alternatively be used without such a layer and may be bonded or otherwise be secured directly to a shoe upper component.
Example II A fibre blend was prepared as in Example (I) but in this case the carded layers were fewer in number so that after needling the overall thickness of the fleece was in the order of 4mm and the weight of the fleece in this case was 67g/m2, thus again giving a density in the order of 0.0167g/cm3 (16.7kg/m3).
Following the needling of the fleece as aforesaid, the fleece is then subjected to a stream of hot air at a temperature in the order of 1200C thus to cause the melt fibres to melt and thereby bond the needled fibres in position. It has been found that by using coarse fibres and fusion-bonding them in this way, the resilience of the fleece is established.
Following manufacture of the fleece in the aforementioned manner the fleece was then laminated to a facina laver: in this Example the facina layer was made of
Aquiline,l a polyester non-woven shoe lining material obtainable from the Applicants. It will of course be appreciated that the fleece is also suitable for laminating with other wear surfaces or for being bonded thereto.
The material exhibited similar properties to the material of Example I and showed itself suitable for use as a shoe upper lining material.
