Definitions

• the invention relates to a thermally fixable fabric, in particular usable as a fixable interlining fabric in the textile industry, with a carrier layer of a textile material, on which a two-ply adhesive composition comprising a binder and a thermoplastic polymer, is applied.
• Inlays are the invisible framework of clothing. They ensure correct fits and optimal comfort. Depending on the application, you can improve processability, increase functionality and stabilize clothing. In addition to clothing, these functions can be used in technical textile applications, e.g. Furniture, upholstery and the home textile industry apply.
• Important property profiles for interlining fabrics are softness, resilience, grip, detergency, and wear resistance of the substrate in use.
• Inlay fabrics can consist of nonwovens, woven fabrics, knitted fabrics or comparable textile fabrics, which are usually additionally provided with an adhesive mass, as a result of which the insert can usually be adhesively bonded to an outer fabric by heat and / or pressure (fixing inlay). The deposit will thus laminated on an outer fabric.
• the various textile fabrics mentioned have different property profiles depending on the manufacturing process. Fabrics consist of threads / yarns in warp and weft direction, knitted fabrics consist of threads / yarns, which are connected via a stitch bond to a textile fabric. Nonwovens consist of single fibers deposited into a batt, which are bound mechanically, chemically or thermally.
• the batt is solidified by mechanically entangling the fibers.
• the fibers For this one uses either a needle technique or an entanglement by means of water or steam jets.
• needling results in soft products, but with a relatively labile feel, this technology was only able to find its way into special niches in the area of interlinings.
• mechanical needling one usually relies on a basis weight> 50 g / m 2 , which is too heavy for a large number of interlining applications.
• Nonwoven fabrics solidified with water jets can be made in lower basis weights, but are generally flat and have little elasticity at break.
• the batt is provided with a binder (eg acrylate binder) by impregnation, spraying or by means of otherwise customary application methods and then condensed.
• a binder eg acrylate binder
• the binder binds the fibers together to form a nonwoven fabric, but results in a relatively stiff product being obtained because the binder spreads over much of the batt and adheres the fibers together throughout, as in a composite. Variations in grip or softness can only be compensated to a limited extent by fiber blends or binder selection.
• Thermally bonded nonwoven fabrics are usually calendered or hot air-solidified for use as interlining materials.
• punctiform calender consolidation has now become established as the standard technology.
• the batt typically consists of polyester or polyamide fibers specially developed for this process and is consolidated by means of a calender at temperatures around the melting point of the fiber, one roll of the calender being dot-engraved.
• Such a dot engraving consists, for example, of 64 dots / cm 2 and may, for example, have a welding surface of 12%. Without a point arrangement, the interlining would be sheet-like solidified and inappropriately hard to handle.
• the adhesive compositions which are usually applied to interlining materials, are thermally activated and usually consist of thermoplastic polymers.
• the technology for applying these adhesive compositions is carried out according to the prior art in a separate step on the fiber fabric.
• adhesive technology usually powder point, paste pressure, colon, scatter, hotmeltrose are known and described in the patent literature. The highest performance in terms of bonding with the outer fabric even after care treatment is now considered the Doppelticianbe Anlagen.
• Such a colon has a two-layer structure, it consists of a lower and a top.
• the sub-point penetrates into the base material and serves as a barrier against adhesive mass recoil and for anchoring the top point particles.
• Usual sub-items consist of for example, from binder.
• the sub-point also contributes, in addition to the anchoring in the base material, as a barrier layer to prevent the adhesive mass backlash.
• Primary adhesive component in the two-layer composite is primarily the top of a thermoplastic material which is sprinkled as a powder on the sub-point. After the spreading process, the excess part of the powder (between the points of the lower layer) is sucked off again. After subsequent sintering, the upper point is bonded to the sub-point (thermal) and can serve as an adhesive to the outer fabric.
• a different number of dots are printed on and / or the amount of adhesive mass or the geometry of the dot pattern is varied.
• a typical number of points are, for example, CP 110 with a run of 9 g / m 2 or CP 52 with a run amount of 11 g / m 2 .
• a disadvantage of the Doppeltician is that it requires a very high machine cost and Invest, since the thermoplastic Obertician first scattered and then the excess between the adhesive mass points consuming must be sucked again. If this process is not successful or not sufficient, undesired grip hardening in the laminate of one-day fabric / outer fabric occurs after fixing and staining of the outer fabric by falling loose polymer particles and, due to the lack of a barrier layer, to layer sticking can occur.
• paste printing Also widespread is the paste printing.
• an aqueous dispersion of thermoplastic polymers, usually in particle form with a particle size ⁇ 80 microns, thickeners and flow aids are prepared and then pasty printed by means of a rotary screen printing process on the support layer usually punctiform. Subsequently, the printed carrier layer is subjected to a drying process.
• Paste printing is in the Bonding performance and in the adhesive mass recoil because of the lack of barrier layer less good than a Haftmassencited after the double-point method.
• Object of the present invention is to provide a textile fixable fabric, in particular for use as a fixable Einlagestoff in the textile industry, which has very good haptic and optical properties, has a very high adhesion to an outer fabric and is also still easy and inexpensive to produce ,
• the thermally fixable sheet according to the invention is characterized by a high adhesion. It has surprisingly been found that a binding point of binder and thermoplastic polymer, which acts as the actual adhesive, has a similar high adhesion as an adhesive mass point of the above-described colon technology. In contrast to this, however, the colon according to the invention can be applied in a one-step process.
• the fact that the thermoplastic polymer is applied not in powder form, but in a mixture with binder occurs in the inventive method, in contrast to the Doppeltician the problem of contamination or unwanted bonding by falling excess or polymer powder not at all.
• the complex process step of suction is also eliminated.
• the inventive thermally fixable sheet is thus easy and inexpensive to produce.
• the selection of the material to be used for the carrier layer, of the binder and of the thermoplastic polymer takes place with regard to the respective application or the special quality requirements.
• the invention has no limits in principle here. The person skilled in the art can easily find the material combination suitable for his application here.
• the carrier layer according to the invention consists of a textile material, such as a fabric, a knitted fabric or a knit or the like.
• the carrier layer consists of a nonwoven fabric.
• the nonwoven, but also the threads or yarns of the above-mentioned other textile materials may consist of chemical fibers or natural fibers.

• the carrier layer can be constructed in one or more layers.
• Fibers with a fiber titer of up to 6.7 dtex are particularly suitable for interlining fabrics.
• Coarser titers are usually not used because of their high fiber stiffness. Fibers are preferred in the range of 1.7 dtex, but also microfibers with a titer ⁇ 1 dtex are conceivable.
• the binder may be a binder of the acrylate, styrene-acrylate, ethylene-vinyl acetate, butadiene-acrylate, SBR, NBR and / or polyurethane type.
• thermoplastic polymer acting as the actual adhesive preferably comprises (co) polyester, (co) polyamide, polyolefin, polyurethane, ethylene vinyl acetate-based polymers and / or combinations (blends and copolymers) of said polymers.
• thermoplastic polymer By the ratio of the amount of binder used to the amount of thermoplastic polymer and by the variation of the wettability of the support layer can be very strong set, abrasion resistant products and very soft nonwoven fabrics with surfaces that can correspond to roughened fabrics obtained.
• High levels of thermoplastic polymer make it possible to achieve very high release forces.
• modifying the surface of the thermoplastic polymer, preferably in particulate form, directly or indirectly from the liquor, its incorporation into the binder matrix can be varied. A very high coverage of the particle surface by other components of the binder matrix is detrimental to the achievable adhesive forces.
• the mixture of binder and thermoplastic polymer which may be based on a liquid, for example in the form of an aqueous dispersion, or in the form of a paste, is preferably applied to the carrier layer in a dot pattern as described above. This ensures the softness and resilience of the material.

• the mixture of binder and thermoplastic polymer may be applied in any geometry, e.g. Example, in the form of lines, stripes, mesh or lattice-like structures, points with rectangular, diamond-shaped or oval geometry or the like.
• the bonding of the fibers of the nonwoven fabric to a nonwoven fabric can be effected mechanically (conventional needling, water jet technique), by means of a binder or thermally.
• a moderate nonwoven strength of the carrier layer prior to printing is sufficient, since the carrier layer during printing with the mixture of Binders and thermoplastic polymer is additionally applied with binder and solidified.
• cost-effective fiber raw materials can also be used, provided that they meet the requirements of the handle. Also, the litigation can be simplified.
• the binder in the dispersion aids in anchoring the polymer particles on the support layer.
• the carrier layer of a textile material or nonwoven fabric can be printed directly in a printing machine with the dispersion comprising the binder and the thermoplastic polymer.
• the mixture is preferably in the form of a dispersion for printing.
• the thermoplastic polymer is preferably in particulate form. It has surprisingly been found that the binder is separated from the coarser particles when printing the textile carrier layer with a dispersion of the particles and the binder and possibly other components, wherein the coarser particles more on the top of the binding surface, for example the dot surface, come to rest.
• the binder binds in addition to its function to anchor in the carrier layer and to bind them additionally, the coarser particles.
• Double-layer adhesive mass points are characterized by a low adhesive mass recoil, since the first applied layer acts as a barrier layer. Surprisingly, also shows the colon-like Bonding point according to the invention, this positive property. Obviously, in the method described here, an in-situ formation of a barrier layer in the bond point occurs, the recoil of the thermoplastic polymer is effectively decelerated, and thereby the positive product properties are strengthened.
