Definitions

  • the invention relates to a textile fixable fabric, in particular usable as a fixable Einlagestoff in the textile industry, comprising a carrier layer of a batt, which is bound in selected surface areas by means of a binder and is unbound in the other surface areas, the support layer at least on one side at least partially is provided with a thermoplastic polymer.
  • 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 interlinings are softness, spring-elastic-like feel, wash and care resistance, and sufficient abrasion resistance of the substrate in use.
  • Inlay fabrics can consist of nonwovens, woven fabrics, knitted fabrics or comparable textile fabrics, which usually additionally with an adhesive are provided, whereby the insert with an outer fabric usually can be thermally bonded by heat and / or pressure (fuser insert). The insert is thus laminated to 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 by a stitch bond to form 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.
  • the mechanical needling usually on surface weight> 50 g / m 2 relies, which is too high for a variety 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 a nonwoven fabric, but has the consequence that a relatively stiff product is obtained, since the binder extends over large parts of the batt and extends the fibers as in a Composite bonded together throughout. Variations in the grip or soft time 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 become established as a standard technology today.
  • 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 nonwoven fabric has a point pattern (point-seal grid).
  • the softness of the interlining is due to the mobility of the fibers between the binding points.
  • the film-like solidified binding point rather contributes to the stiffening.
  • these dot patterns can also look ugly through the outer fabric.
  • an adhesive mass is also additionally printed dot-shaped in a further operation.
  • the two different point structures can achieve a visually disturbing effect when they overlap (moiré effect).
  • 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.
  • Common sub-items consist of binders and / or are polymer-filled mixtures. Depending on the chemistry used, the sub-item also contributes to bonding with the outer material in addition to anchoring in the base material.
  • the main adhesive component in the two-layer composite is the upper point, which is scattered as a powder onto the lower 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 on the sub-point is thermally bonded and can serve as an adhesive to the outer fabric.
  • 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 .
  • 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 textile fixable fabric 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 adhesive, has a comparable high adhesion as the known per se adhesive mass point of 3P / colon structure. In contrast to this, however, the bonding point according to the invention can be applied in a one-step process, wherein this process step also simultaneously involves the application of the binder for producing the nonwoven fabric from the batt.
  • the textile fixable fabric according to the invention is thus also still simple and inexpensive to produce.
  • the fact that the binding point of binder and thermoplastic polymer also partially forms the fiber bonding point at the same time results in a maximum possible mobility of the fibers between the solidification points.
  • the textile fabric is thus characterized by a high resilience elasticity, a high softness and a pleasant feel. Since the textile fabric has no additional applied dot matrix in contrast to the known interlining materials, the unwanted moiré effect known from the prior art does not occur even when using translucent outer fabrics.
  • the Textile fabrics according to the invention thereby provide a pleasant visual appearance.
  • 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 fiber 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. By modifying the surface of the particulate thermoplastic polymer, 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 selection of the fibers 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 fibers for the batt may include man-made fibers such as polyester, polyamide, regenerated cellulose and / or binder fibers and / or natural fibers such as wool or cotton fibers.
  • the man-made fibers can in this case be crimpable, crimped and / or uncrimped staple fibers, crimpable, crimped and / or uncurled, directly spun continuous fibers and / or finite fibers, such as meltblown fibers.
  • the batt 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 which acts as an adhesive composition preferably comprises (co) polyester, (co) polyamide, polyolefin, polyurethane, ethylene vinyl acetate-based polymers and / or combinations (mixtures and copolymers) of the polymers mentioned.
  • the mixture of binder and thermoplastic polymer is preferably applied to the support layer in a dot pattern as described above. This ensures the softness and resilience of the material.
  • the dot pattern may be regular or irregular.
  • the present invention is by no means limited to dot patterns.
  • 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.
  • This unbonded batt can be printed directly in a printing machine with the mixture comprising the binder and the thermoplastic polymer.
  • it may be useful to compress the batt before printing, to wet with textile aids or to treat in any other way so that an increased mechanical fiber-fiber adhesion in Faserflorverbund arises that make the printing process production safer.
  • the mixture is preferably in the form of a dispersion for printing. Since the exact printing of unbonded fibrous webs is difficult, the components of the dispersion used must be precisely matched to the fibrous substrate and to the thermoplastic polymers used.
  • the thermoplastic polymer is in particle form. It has surprisingly been found that the binder is separated from the coarser particles when printing the batt with a dispersion of the particles and the binder and possibly other components, the coarser particles more on the top of the binding surface, such as Point surface, come to rest.
  • the binder binds in addition to its function to anchor in the batt and to bind this to a nonwoven, the coarser particles.
  • the binder penetrates deeper into the material as the particles accumulate on the surface.
  • the coarser polymer particles are incorporated in the binder matrix, at the same time their free surface on the surface of the nonwoven fabric is available for direct bonding to the outer material.
  • Double-layer adhesive mass points are characterized by a low adhesive mass recoil, since the first applied layer acts as a barrier layer.
  • the double-point-like binding point according to the invention also exhibits this positive property.
  • 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.
  • the size of the particles is based on the area to be printed, for example the desired size of a binding point.
  • the particle diameter may vary between> 0 ⁇ m and 500 ⁇ m.
  • the particle size of the thermoplastic polymer is not uniform, but follows a distribution, i. one always has a particle size spectrum. The limits given above are the respective main fractions.
  • the particle size must be matched to the desired order quantity and point distribution.
  • the binders used may vary in their glass transition point, but soft products are usually "soft" binders with one Tg ⁇ 10 ° C preferred.
  • the auxiliaries are used to adjust the viscosity of the paste. With suitable binders, the haptics of the interlining material can be varied within a wide range.
  • the material is subjected to a thermal treatment for drying and bonding fibers of the batt through the binder to a nonwoven fabric and optionally crosslinking the binder and for sintering the thermoplastic polymer onto and / or the nonwoven surface. Subsequently, the material is wound up as a fixable textile fabric.
  • fixable textile fabric is not limited to this application.
  • Other applications are conceivable, for example as a fixable textile fabric for home textiles such as upholstered furniture, reinforced seat structures. Seat upholstery or as a fixable and stretchable textile fabric in the automotive industry, in shoe components or in the field of hygiene / medical.
  • the fixations of the embodiments described below with a proprietary poplin outer fabric were made on a continuous press at 140 ° C and 12 sec.
  • the determination of the separation force is based on DIN 54310 or DIN EN ISO 6330.
  • the separating force values listed are marked with "sp" if the adhesion of the outer fabric / interlining material is so strong during the release force test that the interlining material breaks during the test procedure before complete peeling is carried out. This is a desirable maximum value, since the adhesion is in principle stronger than the internal strength of the interlining.
  • an inner sandwich is sent out of the insert with the outer material to the outside through the fixing press according to the settings specified above.
