Description

Thermally fixable textile fabric Field of the Invention The invention relates to a thermally fixable textile fabric, in particular usable as a fixable inlay fabric, lining fabric and/or outer fabric in the textile industry. The textile fabric is distinguished by a very pleasant surface feel and, at the same time, can be produced with low thickness and high elasticity. The invention further relates to the production of the textile fabric and to its use as an inlay fabric, lining fabric and/or outer fabric for textiles.
Background of the Invention Inlay fabrics are the invisible skeleton of clothing.
They ensure a correct fit and optimal wearing comfort.
They aid in processibility, increase the functionality, and stabilize clothing. Besides clothing, these functions can find use in technical textile applications such as, for example, the furniture, upholstery and home textiles industry.
Lining fabrics are fabrics which are used as lining for textiles, for instances garments or leather goods. A
lining is defined, in textile engineering, as a textile fabric that is fastened by sewing, stitching and/or thermal fixing to the inner sides of textiles. A lining thus constitutes the inner, body-facing fabric layer of clothing. Lining can have the function of making the inner side of a garment more durable, more comfortable and/or warmer, or, perhaps, more decorative. Moreover, the clothing lining has in many cases also a fashionable aspect. Apart from in garments, textile

- 2 -lining is also used in hats, cases, handbags and other containers.
Outer fabrics are fabrics which are used as an externally visible outer fabric layer of textiles.
Advantageous property profiles for inlay fabrics, lining fabrics and outer fabrics are, according to application, softness, resilience, feel, wash resistance and care durability and/or sufficient wear resistance during use. The abovementioned materials generally consist of nonwoven fabrics, woven fabrics, knitted fabrics, or comparable textile fabrics. In particular, inlay fabrics are generally provided with an adhesive substance, whereby the inlay can be bonded to an outer fabric, generally thermally by heat and/or pressure (fixing inlay). The inlay is thus laminated onto an outer fabric. Said various textile fabrics have different property profiles, according to the manufacturing process. Woven fabrics consist of threads/yarns in the warp and weft directions, knitted fabrics consist of threads/yarns which are connected via a knit weave to form a textile fabric. Nonwoven fabrics consist of single fibers, which are laid to form a fibrous web and which are mechanically, chemically or thermally bonded.
At present, thin, transparent, flexible or open outer fabrics, above all in ladies' outer clothing and sportswear, constitute a trend in the clothing industry. Fabrics which are very light and open in their structure are well suited to supporting such outer fabrics.
If elastic outer fabrics are used or if garments are intended to be equipped with elastic properties, then the use of elastic textile fabrics is of advantage.

- 3 -US 8323764 B2 describes a stretchable workpiece, comprising: (a) a porous or microporous woven layer of partially connected droplets of an elastic elastomeric material, wherein the layer has an inner and outer surface; and (b) loose fibers, which are partially embedded in a surface of the layer. Production is realized by the use of a former (a special tool or some other device for the forming of articles or forming material.
The described workpiece is an elastic material which is flocked on both sides and exists in flat or 3D form and the structure of which is defined by the used former.
For its production, a complex process and sophisticated equipment is necessary, i.e. a specific former must be used, as well as a special layer on which the flock fibers are temporarily fixed until the elastomer is applied. Furthermore, the use of the former is necessary in order to produce the elastically flocked surface or coating. In this product, breathability is achieved by spraying of elastomer droplets, wherein the interspaces between these droplets serve as pores and ensure breathability. This means that only a part of the flock fibers which are fixed on the gel/aqueous solution remains in the end product, which results in a higher waste rate. Furthermore, a porosity and breathability with sprayed elastomer droplets is only possible if the thickness of this elastomer coating is very small. This results in a very low mechanical strength of the material. In addition, in the flocking of a 3D shape, for example in concave parts, no uniformly dense flocking can be achieved.
US 9596897 B2 describes a waistband for an article of clothing, comprising an elastic base layer, an elastic mounting layer, and a flocking which is applied to the

- 4 -surface of the mounting layer. The described waistband has the following drawbacks: an "elastic adhesive tape"
(mounting layer 40) is used to support the garment in the waist region (base layer 30), or an elastic knitted fabric, which is sewn or bonded to the base layer 30 with hot-melt film. It is proposed that an adhesive layer 50 is connected both to the base layer 30 and to the mounting layer 40 by pressure (40-60 psi) for 20 to 30 seconds, and heat (150-170 F/66-77 C). With such a low bonding temperature, it is impossible to iron or wash the garment, even just at 60 C. It is also proposed that the band 11 and the base layer 30 are fastened by seams to the clothing body (18), which precludes the possibility of fastening the flocked surface directly to the body of the garment.
US 20090271914 Al describes a garment comprising support bands which are made of an elastomeric adhesive and are flocked with one end of the flock fibers which are embedded in the elastomeric adhesive. Furthermore, a method for producing garments with flock fibers, which are produced using electrostatic or mechanical devices, is described. The main drawback of the method consists in the fact that the clothing manufacturer must acquire the necessary technology/equipment and expertise, for instance in the fields of adhesive screen printing, adhesive spray guns, application of the flock material, air purification/filtering, thermal adhesive drying or curing, in order to be able to perform a direct flocking of the garments after the cutting.
It is desirable to at least partially eliminate the abovementioned drawbacks.
Summary of the Invention

- 5 -In one aspect, the present invention provides a thermally fixable textile fabric, in particular usable as a fixable inlay fabric, lining fabric and/or outer fabric in the textile industry, comprising a support material based on a meltblown fiber nonwoven fabric, wherein the support material has on one side flock fibers and, on the side facing away from the flock fibers, a hot-melt adhesive.
An advantage of the textile fabric according to one aspect of the invention is that it can be easily produced in the form of sheeting comprising flock fibers. In a preferred embodiment of the invention, the textile fabric is hence configured as sheeting. A
fundamental advantage over clothing which has been flocked in the ready-made state is that it enables the clothing manufacturer to use flocked sheeting to create flocked fiber surfaces on a garment merely by cutting and fusion, without having to employ sophisticated flocking technologies.
It is further advantageous that the breathability can be easily achieved by using different degrees of density of the meltblown fiber nonwoven fabric. In the following described flocking process, the adhesive can then be applied to the meltblown fibers, whereby the regions between them remain free and can serve as breathing (air-permeable) pores.
According to the invention, the textile fabric has a support material based on a meltblown fiber nonwoven fabric. The term "based (on)" here signifies at least 90% by weight, related to the total weight of the support material. By the term "meltblown fibers" are understood, according to the invention, fibers that are produced by extrusion of a molten thermoplastic material, through a multiplicity of fine, usually

- 6 -circularly configured nozzle capillaries, as molten fibers into a high-velocity gas (for instance air).
Through this procedure, the diameter of the fibers is reduced. After this, the meltblown fibers are carried by high-velocity gas stream and deposited on a collecting surface in order to form a meltblown fiber nonwoven fabric from randomly distributed fibers. The melt-blowing method is well known and described in various patents and publications, for instance NRL-Bericht 4364, "Herstellung von superfeinen organischen Fasern" [NRL Report 4364, "Production of superfine organic fibers"] by V.A. Wendt, E.L. Boone and C.D.
Fluharty; NRL-Bericht 5265, "Eine verbesserte Vorrichtung fur die Bildung von superfeinen Thermoplastic Fibers" [NRL Report 5265 "An improved device for the formation of superfine thermoplastic fibers], by K.D. Lawrence, R.T. Lukas, and J.A. Junge:
and US Patent No. 3,849,241, granted on 19th. November 1974 to Buntin, et al.
A further advantage of a meltblown fiber nonwoven fabric is that, due to the many fine fibers, the bonding of an adhesive is markedly better than in conventional nonwoven fabrics.
In a preferred embodiment of the invention, the meltblown fibers are formed of polymers, selected from the group consisting of: polyesters, polyolefins, polyamides, polyacrylates, polyvinyl acetates and polyurethanes, copolymers and/or mixtures hereof.
Particularly preferred in this context are polyurethanes, since these have particularly high elasticity. Likewise preferred are thermoplastic elastomers, in particular thermoplastic elastomeric polyesters, polyolef ins and/or polyurethanes.
Thermoplastic elastomers (TPE, occasionally also termed elastoplasts) are plastics which at room temperature

- 7 -behave comparably to the traditional elastomers, yet, under the supply of heat, are able to be plastically deformed and thus display thermoplastic behavior.
In another preferred embodiment of the invention, the meltblown fibers have a fiber linear density of 0.2-5 dtex, preferably of 0.5-3 dtex, in particular of 0.5-2 dtex.
The component of meltblown fibers in the textile fabric preferably amounts to 10% by weight, yet more preferredly from 20% by weight to 60% by weight, in particular from 25% by weight to 55% by weight, respectively related to the total weight of the textile fabric.
According to the invention, the support material has on one side flock fibers. Flock fibers are fibers of small length, which, in the form of loose fibers, are applied to a substrate, here the support material. Depending on fiber thickness and length, a velvety-soft to hard-abrasive surface can be created in accordance with the desired function, visual appearance or surface feel.
The flock fibers can be formed of any natural or synthetic material. Synthetic materials preferably comprise nylon, polyamide, polyester, for instance terephthalate polymers, and natural materials such as cotton, silk, viscose and/or wool.
The length of the flock fibers can be varied according to requirement. Preferably, the flock fibers have a length ranging from 0.3 mm to 1.5 mm, more preferably from 0.4 mm to 0.75 mm, in particular from 0.4 to 0.6 mm.
The linear density of the flock fibers can likewise be varied according to requirement. Preferably, the flock

- 8 fibers have a linear density ranging from 0.5 dtex to 3 dtex, more preferably from 0.9 dtex to 1.7 dtex, in particular from 0.9 dtex to 1.3 dtex.
In addition, the flock fibers can be linear or non-linear. Thus the flock fibers can, for instance, be rolled, crimped and/or bent. Preferably, the flock fibers stand substantially perpendicular to the support material. Alternatively, they can also, however, be disposed in randomly oriented, angled-off and/or substantially parallel arrangement. The fibers used for the flocking can be produced by cutting of filaments to a desired length. The fiber ends created by the cutting can be smooth or unsmooth, for instance jagged.
Preferably, the flock fibers are fixed onto the support material by means of an adhesive. Suitable adhesives are, for instance, acrylate-based, polyurethane-based, silicone-based and/or rubber-based adhesives. By the term "based (on)" should here be understood a component of at least 50% by weight. According to the invention, acrylate-based, polyurethane-based and/or silicone-based adhesives are particularly preferred.
Expediently, the adhesive is a curable adhesive.
In a preferred embodiment, the adhesive has a cross-linking agent. Preferredly, the adhesive in the textile fabric is cross-linked by the cross-linking agent. A
preferred cross-linking agent is a "blocked isocyanate". The term "blocked isocyanate" describes, in accordance with its conventional meaning, the fact that the isocyanate, when brought into contact with the adhesive, exists as an addition compound with a blocking agent, in particular alcohols (urethanes) and/or amines (ureas). At higher temperatures, this addition compound can re-release the isocyanate,

- 9 -whereby the cross-linking of the adhesive can be initiated.
Through the use of the blocked isocyanate, the time of the cross-linkage can be purposefully set. This can prevent a cross-linkage from occurring already during the coating operation, which could lead to irregularities in the coating. Through the use of a blocked isocyanate, a tailor-made degree of cross-linkage can also be set. This results in an improved quality of the adhesive.
According to the invention, particularly preferred blocking agents are selected from the group consisting of 3,5 dimethyl pirazole (DMP), acetoacetic acid, malonic ester, butanone oxime, secondary amines, caprolactam, phenols, alcohols and mixtures hereof.
Quite particularly preferred is in this context DMP, since this gives rise to an excellent cross-linkage of the polymers, is non-toxic and deblocks already at low temperatures, around 120 C to 130 C.
The isocyanate can exist in blocked form in one or more isocyanate groups.
In one embodiment, the adhesive is cross-linked only by means of isocyanate. It is also conceivable, however, that the adhesive, alternatively or additionally to the isocyanate, is cross-linked by means of other cross-linking agents, for example aziridines, polyisocyanates, carbodimides, saccharides, acrylamides, epoxides, amines, oxazolines, urea derivatives, hydrazines and/or carbonic acid hydrazides. Preference is for thermally cross-linked adhesives. These have an advantage over moisture cross-linked adhesives, since the cross-linkage can be purposefully controlled.

- 10 -In a particularly preferred embodiment, the textile fabric has a meltblown fiber nonwoven fabric based on thermoplastic TPU, polyester, polyamide, polyacrylate, polyvinyl acetate, polyolefins, cotton, wool, viscose, lyocell in combination with flock fibers based on polyamide, polyester, polyacrylate, polyvinyl acetate, polyolefins, cotton, silk, wool and/or viscose, with a hot-melt adhesive based on polyamide, polyester, polyolefins, polyacrylates, polyvinyl acetates or polyurethanes, and with a cross-linked adhesive based on polyacrylate, polyurethane, polyvinyl acetate, rubber and/or silicone.
"Based (on)" here respectively means a weight component of more than 50% by weight.
In order to obtain a good elasticity (elongation) of the textile fabric, it is of advantage if the elastic recovery of the adhesive is no less than the elastic recovery of the support material.
In a preferred embodiment, the textile fabric according to the invention has an elasticity, measured according to DIN EN ISO 13934-1 at a force of 3N, in at least one direction, of at least 2%, for instance of 2% to 50%, yet more preferredly of 10% to 20%.
In a preferred embodiment, the textile fabric according to the invention has a permanent elongation, measured according to DIN 53 835, in at least one direction, of at least 0.1%, for instance of 2% to 20%, yet more preferredly of 1% to 5%.
The flock fibers can cover the support material fully or merely in part. If a merely partial coverage of the support material obtains, the flock fibers can form a

- 11 -regular or an irregular pattern. One advantage of a merely partial coverage of the support material is that the air permeability or breathability of the textile fabric can be easily set. Furthermore, it also enables a purposeful setting of modulus and elongation behavior.
In one embodiment of the invention, the textile fabric has a breathability, measured according to DIN EN ISO
9237 at 100 Pa, of more than 20 1/m2s, for instance of 20 1/m2s to 2000 1/m2s. In other embodiments, it can be desirable if the breathability is lower, for instance less than 20 1/m2s, yet more preferredly less than 10 1/m2s, even more preferredly less than 5 1/m2s, and in particular around 0 1/m2s.
The application of the flock fibers to the support material can be realized with various methods, for instance by electrostatic and/or mechanical flocking.
According to the invention, preference is for electrostatic flocking. This is well known and uses loose flock fibers, which are applied in an electric field to the support material coated with an adhesive.
According to the invention, the support material has on the side facing away from the flock fibers a hot-melt adhesive. Hot-melt adhesives, also termed hot glues or hotmelts, have long been known. In general, by these are understood solvent-free products which are applied in the molten state to an adhesive surface, rapidly harden upon cooling, and hence rapidly build up strength. According to the invention, preferredly thermoplastic polymers, such as polyamides (PA), copolyamides, polyesters (PES), copolyesters, ethyl vinyl acetate (EVA), and copolymers thereof (EVAC), polyolefins, in particular polyethylene (PE),

- 12 -polypropylene (PP), amorphous polyalphaolefins (APAO), polyurethanes(PU), and mixtures hereof, are used as hot-melt adhesives. According to the invention, co-polyamides, co-polyesters and polyurethanes are particularly preferred.
The adhesive effect of holt-melt adhesives is essentially based on the fact that they are able to be reversibly melted and, as liquid melt, due to their reduced viscosity resulting from the melting operation, are capable of cross-linking the surface to be bonded and thereby form an adhesion to this. As a consequence of the subsequent cooling, the hot-melt adhesive rehardens to a solid, which solid has a high cohesion and, in this way, establishes the connection to the adhesive surface. After the bonding has taken place, the viscoelastic polymers ensure that the adhesion is maintained also after the cooling operation, with their volume changes and the therewith associated build-up of mechanical stresses. The developed cohesion imparts the bonding forces between the substrates.
In one embodiment, the hot-melt adhesives are used in powder form. The size of the particles is oriented to the area to be printed, for instance to the desired size of a bond point. In the case of a dot pattern, the particle diameter can vary between >0 pm and 500 pm. In principle, the particle size of the hot-melt adhesive is not uniform, but follows a distribution, i.e. a range of particle size is always present. Expediently, the particle size is tailored to the desired application volume, dot size and dot distribution.
Hot-melt adhesives in powder form can be applied by means of scattering application, which, in particular, for the bonding of porous substrates, is expedient for the production of altogether breathable textile

- 13 -composites. A further advantage of scattering application is that it is a simple application method for large-scale applications. Since thermoactivated powders, for instance of polyamides, polyesters or polyurethanes, are adhesive already at low temperatures, they are suitable for gentle lamination of heat-sensitive substrates, for example high-value textiles. By virtue of good flow characteristics in the activated state, a good connection is established even at low pressure and with short pressing time;
nevertheless, the risk of bleeding into the fabric remains low.
The hot-melt adhesive can also be applied to the meltblown fiber nonwoven fabric by means of paste printing, double-dot and hot-metal processes. According to the invention, the past printing process is particularly preferred, since feel and elasticity are hereby maintained particularly well.
Due to the use of a meltblown fiber nonwoven fabric as the base material, the areal weight of the textile fabric according to the invention can be set very low.
Areal weights, measured according to DIN EN 29073, ranging from 10 g/m2 to 400 g/m2, preferably from 25 g/m2 to 200 g/m2, and in particular from 30 g/m2 to 100 g/m2, have proved expedient for many applications.
Further preferably, the textile fabric has a thickness, according to DIN EN ISO 9073-2, of 0.5 mm to 1.6 mm, preferably of 0.5 mm to 0.9 mm.
Further preferably, the textile fabric has a modulus, measured according to DIN 53 835 at an elongation of 25%, of less than 20 N, for instance of 1 N to 20 N, preferably of 2 N to 10 N. The comparatively low modulus of the textile fabric is advantageous, since

- 14 -the fabric is able to stretch without great application of force and thus adapts perfectly to the body contours.
Due to its specific properties, the textile fabric is eminently suitable as a fixable inlay fabric, lining fabric and/or outer fabric in the textile industry.
Preferred inlay fabrics for combination with the meltblown fiber nonwoven fabric according to the invention are selected from knitted or woven elastic fabrics, from natural or synthetic yarns, or combinations hereof. These fabrics can also comprise highly elastic yarns. Preferred lining fabrics for combination with the meltblown fiber nonwoven fabric according to the invention are selected from elastic real leather of animal origin or artificial leather.
Preferred outer fabrics for combination with the meltblown fiber nonwoven fabric according to the invention are selected from laminated nonwoven fabric or loose membranes.
The invention also relates in one aspect to a method for producing a thermally fixable textile fabric according to the invention, comprising the following steps:
A) provision of a support material based on a meltblown fiber nonwoven fabric;
B) application of flock fibers to one side of the support material;
C) application of a hot-melt adhesive to that side of the support material that is facing away from the flock fibers.
One advantage of the method according to the invention is that the meltblown fiber nonwoven fabric can be

- 15 -flocked in the unformed, i.e. flat state. The maximum flock fiber density can hereby be achieved.
The provision of the support material in step A) can be realized by meltblowing of a nonwoven fabric raw material, preferably polyurethane. In a preferred embodiment, the support material is formed on an auxiliary support, for instance a spunbond nonwoven fabric, whereby a higher stability and easier reprocessibility is conferred to it. Preferably, the provision of the support material consequently comprises the fixing thereof on an auxiliary support.
In one embodiment of the invention, the application of flock fibers to one side of the support material is subsequently realized in step B). Preferably, the application of the flock fibers comprises the upstream step of applying an adhesive.
According to the invention, electrostatic flocking is preferred. The flock fibers are here applied in an electric field to the adhesive-coated support material.
If an auxiliary support is used, then adhesive and flock fibers are applied to that side of the support material that is facing away from the auxiliary support. The application of the adhesive can be realized by screen printing, spray gun or immersion bath. The surface of the support material is preferably smooth or only very slightly embossed or grooved. The field lines ensure that the flock fibers orient themselves at a desired angle, preferably vertically, and thus create an even, textile surface. Subsequently, the adhesive can be cured and the flocking anchored.
Excess and unbonded flock fibers can be removed by vacuum.

- 16 -Likewise conceivable is a mechanical flocking for fastening of the flock fibers. For this, the support material provided with the adhesive can be guided over a series of, preferably polygonal, rollers, which quickly set said support material into vibrations. This vibration can propel the flock fibers into the adhesive.
Following the flocking, the auxiliary support, where used, can be removed and, after this, a hot-melt adhesive can be applied to that side of the support material that is facing away from the flock fibers (method step C). The hot-melt adhesive can be applied to the meltblown fiber nonwoven fabric by means of paste printing, double-dot, scattering and hotmelt methods. According to the invention, the paste printing method is particularly preferred.
In an alternative embodiment of the invention, method step C) is performed prior to method step B).
The invention consequently relates to a method for producing a thermally fixable textile fabric, comprising the following steps:
A') provision of a support material based on a meltblown fiber nonwoven fabric;
B') application of a hot-melt adhesive to one side of the support material;
C') application of flock fibers to that side of the support material that is facing away from the hot-melt adhesive.
In a preferred embodiment, the support material is formed on an auxiliary support, for instance a spunbond nonwoven fabric. If an auxiliary support is used, then the hot-melt adhesive is applied to that side of the

- 17 -support material that is facing away from the auxiliary support, and said support material is removed again prior to the application of the flock fibers.
In this method variant too, the application of the flock fibers preferably comprises the upstream step of applying an adhesive.
