Abstract

A composite material comprises a flexible non-textile sheet-form material and at least one textile sheet- form material produced from synthetic fibre(s), the textile sheet-form material(s) being produced using textured yarn(s). The material is used to produce inflatable handballs and footballs.

Description

SPECIFICATION Composite material comprising a flexible, non-textile sheet-form material and at least one textile sheet-form material This invention relates to a composite material comprising a flexible, non-textile sheet-form material and at least one textile sheet-form material; more particularly, it relates to a composite material comprising a flexible, nontextile sheet-form material and at least one textile sheet-form material produced from synthetic fibres and to the use of such a composite material, particularly for the production of sports balls.
Composite materials of the type in question have been repeatedly described in the past.
Thus, skiver of relatively poor quality has been made more durable by backing using silk cloth or by applying a fabric backing using adhesives (German Patent Nos. 214, 902 and 247,060). Attempts have been made to improve the dimensional stability of leather camera cases by backing the leather using pieces of fabric impregnated with curable pheonoplasts (German Patent Application L 11 522 Vll/28b, published 20.9.56). Attempts have also been made to improve the strength and stitch-holding capacity of leather for shoe upper material by backing the leather using sheet-form textile materials produced from synthetic fibres in plain of linen weave (German Offenlegungsschrift No. 1,435,315).
Furthermore, it has proposed in German Offenlegungsschrift No. 1,760,286 to apply a sheet-form textile material, for example a knitted fabric, a non-woven fabric or a woven fabric of synthetic fibres, to the gain side of the pieces of low-quality leather after smoothing the grain with a view to increasing tensile strength.
Recently, attempts have also been made to improve the dimensional stability of sports balls, particularly hand-balls and footballs, by backing the cover consisting of leather, artificial leather or PVC film using from 1 to 3 layers of woven fabrics produced from synthetic fibres. This is said to provide the balls from the outset with improved roundness which they retain, even in the event of prolonged use, particularly in wet weather. In addition to the playing and flight characteristics, the increase in weight attributable of moisture adsorption may also be influenced by using composite materials with sheet-form textiles produced from synthetic fibres.
In all cases where attempts are made to strengthen flexible non-textile sheet-form materials by backing using sheet-form textile materials or to improve the dimensional stability of articles produced from such a composite material, the most important requirement is a firm and permanent joint between the various sheet-form materials. This requirement is not adequately satisfied in conventional composite materials because, on the one hand, smooth, untwisted or twisted synthetic yarns are used and because, on the other hand, the sheetform textile materials used, on account of the conventional construction thereof, behave differently from the non-textile sheet-form material to be improved, particularly in regard to the elasticity thereof in various directions.
Another disadvantage of known composite materials lies in the poor tear propagation resistance thereof and the resulting weakness of,stitched seams in made-up articles. In the case of sports balls, tear propagation resistance in the vicinity of the seams ("stitchholding capacity") plays a particularly important role where the cover is made up of strips of leather.
An object of the present invention is to provide a composite material of the type mentioned above in which the particular structure of the sheet-form textile material provides for a firm and durable join between the various sheet-form materials and, at the same time, effectively strengthens and improves the dimensional stability of the articles produced from the composite material and also increases stitch-holding capacity in the case of articles made up by stitching. It is also an object of the present invention to provide a sports ball which combines high dimensional stability with improved roundness and reduced water absorption and in which the various sheet-form materials forming the composite material enter into a firm and durable join coupled with a high stitch-holding capacity.
According to the present invention, the objects are achieved in that the textile sheetform material(s) is/are produced using textured yarns.
In the context of the present invention, a "sheet-form material" is to be understood to be a substantially two-dimensional material which has very little thickness compared to its length and width. Examples of sheet-form materials corresponding to this definition are leather skins, paper in sheet or web form, plastics in film or sheet form and, in particular "textile sheet-form materials", i.e. sheet-form materials produced from fibres, such as sheetform materials knitted or woven from yarns, fleeces, felts or mats, for example.
"Textured yarns" are, on the one hand, filament yarns which, in the original state thereof, consisted of a plurality of parallel individual filaments, but in which the parallelism of the individual filaments has been eliminated by a texturing treatment (for example by blow-nozzle interlacing, blow-nozzle looping, compression crimping, false-twist crimping, crinking, blade crimping or knit-deknit treatment), and, on the other hand, staple fibre yarns of which the surface has been given an additional structure by a texturing treatment (for example false-twisting or compression crimping).
Where it is proposed in accordance with the present invention that the textile sheet-form material(s) be made "using textured yarns", this means that there is no need to use only textured yarns. Depending on the nature of the non-textile sheet-form material and/or of the textile sheet-form material, it may be sufficient to use a sheet-form material produced only partly from textured yarns. For example, it may be sufficient to use a woven fabric in which only the warp or the weft consists of tertured yarns or a two-layer fabric composite in which the fabric facing the non-textile sheet-form material is made of textured yarns.
The greater the proportion of textured yarns in the composite materials, the better the join will be. Accordingly, the proportion of textured yarns preferably amounts to more than 50%. by weight, more particularly to from 70 to 100%, by weight. The higher the proportion of textured yarns, the higher the tear propagation resistance in the region of seams, ("stitch-holding capacity").
The textured yarns may be staple fibre or filament yarns, filament yarns being preferred.
Among the various texturing processes which may be used, preference is given to an air-jet treatment which produces blow-looped yarns from filament yarns. Accordingly, one preferred embodiment of the present invention is characterised in that the textured yarns are air-jet-bulked, blow-looped yarns produced from filament yarns. The loops and eyes which are present at the surface of such blowlooped yarns and which are firmly anchored in the filament assemblage provide for improved mechanical adhesion when the sheet-form materials are being joined together and, in particular, form a large effective surface where the sheet-form materials are joined together by bonding.
Since the function of the textile sheet-form materials joined to the non-textile sheet-form materials is to increase the strength and tear propagation resistance thereof and/or to improve the dimensional stability thereof, for example favourably to influence the elasticity thereof, it is advantageous if the textured yarns have certain minimum values in regard to the textile properties thereof.
Thus, the tensile strength of the textured yarns should amount to at least 35 cN/tex.
Depending on the texturing process used, it is necessary to use a filament yarn characterised by considerably higher tensile strength as the starting material. Where air-jet-bulked loopedblown yarns are used, the initial strength of the filament yarn to be textured must be higher by 100% than the reqired tensile strength of the textured yarns. Known higherstrength filament yarns are available for this purpose, being characterised by a tensile strength of more than 65 cN/tex, preferably more than 70 cN/tex.
Where it is a question of improving the dimensional stability of non-textile sheet-form materials having high elasticity (for example flexible PVC sheeting or wet leather), it is advisable to use textile sheet-form materials of low elasticity. This may be done by the construction of the sheet-form material (knitted fabrics are more elastic than woven fabrics) and may also be decisively influenced by the elongation of the yarn. Accordingly, the textured yarns should preferably have a breaking elongation of less than 25%, values below 20% being preferred. From the point of view of the preferred low elongation level as well, it is advisable to use loop-forming blow texturing as the texturing process because the elongation level of the yarn does not change to a significant degree in this particular texturing process.Starting with a filament yarn having a breaking elongation of the order of 18%, a textured yarn having substantially the same elongation is obtained.
Where the sheet-form materials are to be joined together at elevated temperatures, it is advisable to use textile sheet-form materials of textured yarns which are characterised by low shrinkage at temperatures of this order. The textured yarns should preferably have a shrinkage in hot air (1 5 minutes at 1 90"C) of less than 10% and, more particularly, less than 5% and a boiling-induced shrinkage (60 minutes at 100"C) of less than 5% and, more particularly, less than 1%.
As mentioned above, textured yarns comprising endless filaments are preferred to textured staple fibre yarns. In general, they provide for improved strength values and for greater versatility in surface texturing by corresponding texturing processes. In particular, filament yarns may be effectively subjected to a loop-forming blowing treatment.
The textured yarns may be produced from natural and/or synthetic fibres. Synthetic fibres may be spun by various methods, for example by wet spinning, dry spinning or melt spinning. Textured yarns of melt-spinnable synthetic polymers, such as polyamides, polyesters or polyolefins, are preferred by virtue of the favourable textile properties thereof and the adequate commercial availability thereof. Nylin (polyamide -6,6) and polyethylene terephthalate are particularly preferred.
It has been mentioned above that an object of the present invention may be achieved by the structure of the textile sheet-form material, and hence, also by the construction of the textile sheet-form materials used. This does, of course, pre-suppose the use of textured yarns.
Since knitted fabrics generally have high structural elasticity which, in addition, is not the same in all directions, fleeces have the same disadvantages and felts (of staple fibres) show inadequate strength, woven fabrics or stitch-knitted fabrics (weft double-rib fabrics) are preferably used as the textile sheet-form materials. In the case of woven fabrics, it may be advantageous so far as further processing into the composite material according to the present invention is concerned to use yarns of different elasticity in the warp and weft.
The non-textile sheet-form material may be combined with one or more textile sheet-form materials. Backing using a textile sheet-form material, for example using a woven fabric, is known from the leather field where woven fabrics of which the warp and weft form an angle of 90 with one another are normally used. A warp filament and a weft filament system is normally used for producing "traditional" woven fabrics of this type. In order to obtain strength, elongation and shrinkage properties which are substantially the same in all directions of the fabric, it is advisable to use a so-called "triaxial" woven fabric. Two warp filament systems (which are introduced at an angle) and one weft filament system are required for producing woven fabrics of this type.
Where particularly stringent requirements have to be satisfied, the flexible non-textile sheet-form material may also be combined with a composite of two woven fabrics, the weft filament systems of the two fabrics preferably extending at an angle of 45 to one another. Other combinations, for example of two woven fabrics offset at 90 , of three woven fabrics each offset at 60 or several different textile sheet-form materials are possible. That side of the composite remote from the non-textile sheet-form material may also be additionally coated or flocked, for example, in order aesthetically to improve the composite material. In most cases, it is not advisable to use more than three layers of textile sheetform materials because this would make the composite too expensive, too heavy and too stiff.
There are various possible ways of joining the textile sheet-form material(s) (optionally in the form of a composite) to the non-textile sheet-form material. In addition to stitching or sewing, it is possible in particular to use stitch-knitting techniques. The sheet-form materials are preferably bonded to one another because there are several ways of doing this and because it is possible to obtain a surfaceto-surface bond which has substantially the same strength in all directions. In addition to using conventional adhesives of the type which may be activated by pressure and/or temperature, it is possible to insert low-melting films between the two surfaces to be bonded, followed by a pressure/heat treatment, or to use fibres having different melting points, optionally two-component fibres in which one component melts at a higher temperature than the other component.Bonding and stitching or sewing may also be combined with one another.
Suitable flexible non-textile sheet-form materials are, for example, paper, cardboard or card in web form; flexible PVC sheeting; synthetic upper material based on coated fabrics, fleeces or films. It is preferred to produce a composite material based on leather, in which case it is possible to back both low-quality skiver and also high-quality chrome leather.
The composite material according to the present invention may be used as an upper material for shoes or boots, for example. It may also be used as a high-quality tarpaulin material for lorries, as a soft-top material for convertible cars or as a cover for building sites for example. The composite material according to the present invention is preferably used for the production of sports balls, particularly high-quality leather and plastic balls, of the type used as footballs, hand balls, medicine balls or punchballs, for example, more particularly for inflatable leather handballs and footballs. Such balls are dimensionally stable, even after prolonged use. The composite material according to the present invention is also preferably used as a furniture covering, particularly for covering chairs where dimensional stability is particularly crucial.Furthermore, the composite material according to the present invention is also particularly suitable for the production of drive belts of which the contact surfaces (inner surfaces) are normally made of leather.
The present invention is illustrated in the accompanying drawing, wherein: Figure 1 is a diagrammatic, partly sectional view of a composite material according to the present invention.
Figure 2 is a diagrammatic side elevation of a preferred blow-looped yarn.
Fig. 1 shows a non-textile sheet-form material 1, for example a piece of leather, to the back of which are bonded two textile sheetform materials 2; 3, namely two conventional woven fabrics of which the warp and weft extended at 90 to one another. The lower fabric (2) and the upper fabric (3) rest on one another in such a way that the warp filaments of the two fabrics are at an angle of 45 . The fabric composite (2,3) has suprisingly isotropism in regard to strength and elongation. It is suitable together with leather for the production of high-quality, dimensionally stable footballs which are distinguished by the high stitch holding capacity thereof.
Fig. 2 shows an air-jet-bulked, blow-looped yarn 4 in the core of which eyes 5 and loops 6 projecting from the surface are firmly anchored. A yarn of this type is particularly suitable for producing the textile sheet-form material of textured yarns which is used in the composite material according to the present invention.
