Abstract
ABSTRACT
An insole, comprising an absorbent layer of moisture retaining fibres, and a moisture permeable layer of textile material, this being superimposed on and affixed to the absorbent layer, the moisture permeable layer consisting of water-repellant fibres, the fibres incorporating pores that are capillary active and that pass moisture through the moisture permeable layer from the top and into the absorbent layer.
An insole, comprising an absorbent layer of moisture retaining fibres, and a moisture permeable layer of textile material, this being superimposed on and affixed to the absorbent layer, the moisture permeable layer consisting of water-repellant fibres, the fibres incorporating pores that are capillary active and that pass moisture through the moisture permeable layer from the top and into the absorbent layer.
Description
~Z45~)53 The present invention relates to a liner sole or an insole, consisting of an absorbent layer of moisture retaining fibres and a moisture permeahle covering layer of woven material that is superimposed on and affixed to the top of this absorbent layer.
An i.nsole of the general type described above is commercially available.
The absorbent layer is covered on top by a covering layer of woven cotton fabric and beneath by an under layer of cork, the covering layer and the under layer being stitched together through the absorbent layer. Because of the special arrangement of the stitches relative to the insole, small-scale production is impractical, and this increases production costs. In addition to this, the covering layer of woven cotton fabric has moisture retaining properties that are similar to that of the absorbent layer itself. For this reason, any moisture that is absorbed can always be detected in the vicinity of the upper side of the covering layer, which results in a considerable reduction in wearer comfort.
It is the task of the present invantion to develop a liner sole or insole for footwear, this being economical to produce ana which, even after moisture has been absorbed, always feels dry.
According to the present invention, this task has been solved by a liner sole or insole of the type described in the introduction hereto, in that the covering layer is of water-repellant fibres and in that the fibres incorporate surface-active pores that pass from the upper side of the covering layer through to the absorbent layer.
Unlike the absorbent layer, the covering layer of the insole according to the present invention has no actual water retention capability. Moisture on the upper side is thus moved down towards the absorbent layer, which means that the top side always feels dry. Thus, the insoles are considerably more comfortable to the wearer.
It is preferred that the covering layer consists of an inherently stable surface structure, for example, a woven fabric, a knitted fabric, or a f]eece. If a woven fabric or a Xnitted fabric is used, it is possible to produce 100% of the covering layer from water-repellant fibres. If a fleece is used, it becomes necessary to combine the fibres, which are in a random arrangement relative to each other, to achieve sufficient strength. At small surface weights, this ordinarily requires that the fibres be welded together - 1- ~'~
lZ~53 and/or additionally a bonding agent be used. In many cases this will mean a loss of textile-like qualities--particularly of fabric softness---and this will have to be accepted.
In particular, the use of woven fabrics that display good softness in addition to good shape retention qualities is preferred for this reason.
The covering layer can have fibres that extend vertically from its top surface, and this faciLitates the removal of moisture that is generated.
suitable surface structure can be achieved, for example, by roughening or abrading the surface.
The proposed insole can be produced by stamping the parts thereof Erom flat (sheet) stock. Thus, production is economical and is, in particular, suitable for mass production. In order to ensure a good transfer of moisture from the cover layer to the absorbent layer, it has, in each instance, been found to be particularly advanta~eous if the covering layer contains fibres that are stitched into the absorbent layer.
The use of a suitable technology is recommended primarily if the absorbent layer is also of a textile material, for example, a fleece of Eibres that contain viscose. Stitching dow~ the covering layer and the absorbent layer can also be used to ensure that there is a high-strength joining of both layers. The use of secondary technologies can thus be dispensed with.
According to another embodiment, it is foreseen that the covering layer and the absorbent layer are cemented together in zones that are evenly distributed across the whole of the contact surfaces by points or lines, lt being preferred that this be done by a fusible adhesive. This adhesive can be arranged optionally in the form of an inherently stable mesh or fleece between the coverin~ layer and the absorbent layer, and the structure obtained thereby can be activated by hot calendering. The use of contact cements, chemically cross-linXed cements, solvent-softened cements, or dispersion cements is also possible. The mutual joining of the covering layer and the absorbent layer can optionally take place away from the textile plant, for example, in the shoe production plant. The specific matching of the covering layer and the absorbent layer to the specific requirements of shoe production is simplified thereby.
The advantages achieved by the proposed insole are primarily that the upper side always feels warm and dry, regardless of the volume of moisture ~LZ9t5~53 that has been retained. The pores that pass through the coverin~ layer and wh;ch are capillary active cannot become plugged and moisture that is absorbed is thus transferred rapidly through the upper side during long-term use, for example, at night, when the footware is not in use.
An exemplary version of the insole accordin~ to the present invention is described in greater detail on the basis of the drawing appended hereto.
The insole that is illustrated comprises the covering layer 1 and the absorbent layer 2. These are joined together by stitching and are of a total thickness of 1.5 - 5 mm, preferably from 2.5 - 3.5 mm.
The insole that is illustrated is stamped out of flat sheet stock, this having a surface weight of at least 200 g/m , preferably between 400 and 1200 g/m .
Of the total wei~ht per square metre that has been cited, at least 607~-wt and at most 9570-wt is accounted for by the absorbent layer, and at least 407~wt and at least 5%~wt is accounted for by the covering layer.
The absorbent layer consists of at least 507vwt absorbent fibres, which can be natural or synthetic. In addition to wool, cotton, and/or wood pulp, totally synthetic hollow or pore fibres are preferred for use. Favourable characteristics can be achieved by the use of wood pulp and/or super absorbent fibres, such as, for example, wood pulp fibres impregnated with carboxymethyl cellulose. The fibres can optionally be cemented with a bonding agent that is also included. The incorporation of odour inhibitors, for example, bactericides and/or fungicides, as well as of activated charcoal, is also possible.
The covering layer consists of water-repellant fibres that should have the best-possible resistance to abrasion. Polyester fibres are preferred for this purpose. In this case, the surface of the insole is characterized by an especially dry and textile-like feel under all conditions. The use of polypropylene fibres, polyamide fibres, polyacryl fibres, PVC fibres, and other water-repellant fibres can also be considered. These fibres are generally available at a more favourable cost.
According to their formations, which are effected independently of each other, the covering layer and the absorbent layer are superi~nposed on each other and stitched together from the direction of the covering layer. The overall structure so obtained is characterized by good strength and can be ~245~53 used directly a~ the raw material for stampin~ out the individual insoles.
The proposed insole has a water absorption factor of at least lOO~wt, preferably lS0-40070-wt. It dries rapidly overnight, and is completely washable.
An i.nsole of the general type described above is commercially available.
