Description

The Invention relates to a thermally fixable sheet, especially usable as a fixable interliner in the textile industry, comprising a carrier layer of a batt, which in selected areal areas by means of a Binders bound and in the remaining surface areas is unbound, wherein at least on one side of the carrier layer a two-ply adhesive mass structure comprising a binder and a thermoplastic polymer is applied.

interlinings are the invisible framework of clothing. They worry for correct fits and optimal comfort. ever after application, they help to increase processability the functionality and stabilize the clothing. Next clothing, these features can be used in technical textile applications, z. As furniture, upholstery and home textiles industry application Find.

Important Property profiles for interlining materials are softness, elasticity of elasticity, Handle, washing and care resistance as well as sufficient Abrasion resistance of the substrate in use.

interlinings can be made of nonwovens, fabrics, knitted or comparable textile fabrics exist, which usually in addition are provided with an adhesive mass, whereby the insert with a Outer material is usually thermally bonded by heat and / or pressure can (fixation). The insert is thus on an outer fabric laminated. The mentioned various textile fabrics have different property profiles depending on the manufacturing process. Fabrics consist of threads / yarns in warp and weft directions, Knitted fabrics consist of threads / yarns, which have one Mesh bond connected to a textile fabric become. Nonwovens consist of single fibers deposited to a batt, which are bound mechanically, chemically or thermally.

For mechanically bonded nonwovens, the batt is solidified by mechanically entangling the fibers. For this one uses either a needle technique or an entanglement by means of water or steam jets. Although needling results in soft products, but with a relatively labile feel, this technology was only able to establish itself in very special niches in the area of interlining materials. In addition, mechanical needling usually relies on a basis weight of> 60 g / m ² , which is too heavy for a variety of interlining applications.

With Water jets solidified nonwovens can be in lower Area weights, but are generally flat and little jump elastic.

at chemically bonded nonwovens, the batt is impregnated, Spraying or using otherwise customary methods of application provided with a binder (eg Acrylatbinder) and then condensed. The binder binds the fibers together A nonwoven fabric, however, has the consequence that a relatively stiff product is obtained because the binder over large parts extends the batt and extends the fibers as in a composite material glued together throughout. Variations under control

softness can be limited only by fiber blends or binder selection compensate.

Thermally bonded nonwoven fabrics are usually calendered or hot air-solidified for use as interlining materials. In the case of interlining nonwovens, punctiform calender consolidation has become established as a standard technology today. The batt usually 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 provided with a dot engraving. Such a point engraving is z. B. from 64 points / cm ² and z. B. have a weld of 12%. Without a point arrangement, the interlining would be sheet-like solidified and inappropriately hard to handle.

Although the dot arrangement produces sufficiently soft products depending on the fibers used, 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, however, rather contributes to the stiffening. On very light, thin outer fabrics, these dot patterns can also look ugly through the outer fabric. In addition, 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). Although there are sufficiently soft interlining fabrics with an appealing handle, but are more common in the standard technology Approx. 10-45% of the insert is consolidated and covered by means of a point-seal grid and adhesive mass application.

The described above different methods for the preparation of Textile fabrics are known and in textbooks and described in the patent literature.

The Adhesive compositions, which are usually applied to interlining materials are thermally activated and are usually made of thermoplastic Polymers. The technology for applying these adhesive coatings takes place according to the prior art in a separate step on the fiber fabric. As adhesive technology are usually powder dot, paste pressure, colon, litter, Hotmeltverfahren known and described in the patent literature. As most efficient in terms of bonding with the Outer fabric even after care treatment is today the Doppelpunktbeschichtung considered.

One such colon has a two-layer structure, it consists from a lower and a higher point. The subpoint penetrates into the Base material and serves as a barrier against adhesive mass recoil and for anchoring the top point particles. Usual subpoints consist for example of binder. Depending on the chemistry used the sub-point is next to the anchorage in the base material also as a barrier to prevent the adhesive mass backlash at. Main adhesive component in the two-layer composite is primary the top of a thermoplastic material, which as Powder is sprinkled on the sub-point. After the spreading process is the excess part of the powder (between the points of the lower layer) sucked off again. After afterwards Sintering is the upper point on the sub-point (thermally) bound and can serve as an adhesive to the top.

Depending on the intended use of the interlining material, 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 z. B. CP 110 at a supply quantity of 9 g / m ² or CP 52 with a quantity of 11 g / m ² .

adversely At the colon technology is that they require a lot of machinery and Invest requires, since the thermoplastic top point material first scattered and then the surplus between the Adhesive mass points consuming again must be sucked off. If this process is not successful or not sufficient, then arise after fixing unwanted grip hardening in the laminate Interlining / outer fabric, and it may cause contamination of the outer fabric due to falling loose polymer particles and because of the missing barrier layer come to Lagenverklebungen.

Far common is the paste printing. With this technology will an aqueous dispersion of thermoplastic polymers, usually in particle form with a particle size <80 μm, Thickeners and running aids produced and then pasty usually by means of a rotary screen printing process on the carrier layer punctiform imprinted. Subsequently, the printed carrier layer subjected to a drying process. Paste printing is in detention and in detention mass kickback because of the missing barrier layer less well than a Haftmassenauftrag proceed after the colon.

task of the present invention is a textile fixable sheet, in particular for use as a fixable interlining material in the Textile industry, which provide very good haptic and has optical properties, a very high adhesion owns to an outer fabric and beyond simple and inexpensive to produce.

These Task is with a textile fixable fabric solved with all features of claim 1. preferred Embodiments of the invention are in the subclaims described.

The Thermally fixable fabrics according to the invention is characterized by a high adhesion. It has It has surprisingly been shown that a binding point from binder and thermoplastic polymer, which is considered the actual Adhesive acts, a comparable high adhesion has like an adhesive mass point of the above-described colon technology. In contrast to this, the inventive Colon but apply in a one-step process. Thereby, that the thermoplastic polymer is not in powder form, but in is applied to a mixture with binder occurs in the inventive Method in contrast to the colon technology the problem of Contamination or unwanted sticking by sloping waste Polymer powder not at all. The elaborate Suction process also disappears. the Thermally fixable fabrics according to the invention is thus easy and inexpensive to produce.

Thereby, that the binding point of binder and thermoplastic polymer at the same time partially forms the fiber bonding point results a maximum possible mobility of the fibers between the Consolidation points. The textile draws thus by a high elasticity, a high elasticity Softness and a pleasant grip. As the textile fabric in contrast to the known Einlagestoffen no additional has applied dot matrix, also occurs from the state of Technique well-known unwanted moiré effect too when using translucent outer fabrics not on. The invention Textile fabrics thus provide a pleasant visual Appearance.

There it is a bond with a binder are not expensive special fibers necessary as in the thermal consolidation However, according to the point-seal method can be z. B. with special crimped fibers are also more likely to produce elastic products.

By the ratio of the amount of binder used to Amount of thermoplastic polymer and by the variation of the wettability The fibrous web can be very strong set, abrasion resistant Products and very soft products with surfaces that Roughened tissues can be obtained. By high Shares of thermoplastic polymer can be very high separation forces realize. By modification of the surface of the preferably particulate thermoplastic polymer, direct or indirectly from the fleet, its incorporation, in the binder matrix be varied. A very strong occupancy of the particle surface by other components of the binder matrix is achievable Detention forces detrimental.

The Selection of the carrier layer to be used Fibers, the binder and the thermoplastic polymer takes place with regard to the particular application or the particular Quality requirements. By the invention are in principle here no limits. The expert can easily do this for find his application suitable combination of materials.

So The fibers of the batt can be made of chemical fibers or but also consist of natural fibers. As man-made fibers come preferably Polyester, polyamide, cellulose regenerating and / or binding fibers for Use, as natural fibers wool or cotton fibers.

A preferred method for producing a thermally fixable sheet according to the invention comprises the following measures:

• a) Provision of a carrier layer of a batt, z. B by producing a carrier layer from a batt of fibers on a storage device in a manner known per se,
• b) pretreating the carrier layer by means of a low pressure water jet method,
• c) Then preferably setting the fiber-textile material to a process-specific moisture content

• e) heat treating the fibrous web obtained from step c) with the mixture for drying and bonding fibers of the fibrous web through the binder to a nonwoven fabric and optionally crosslinking the binder and for sintering the thermoplastic polymer onto and / or with the support layer surface Binder.

For the production of the batt can be known per se Technologies are used. For the weakly bound Flannel with moderate nonwoven strengths can be cost effective Fiber raw materials are used, provided that they meet the requirements to meet the handle. Also, the litigation be simplified. The binder in the dispersion helps the anchoring of the polymer particles on the carrier layer.

in the In the case of using staple fibers, it is advantageous to use these with at least one card to card a batt. Prefers Here is a Wirrlegung (random technology), but also combinations from longitudinal and / or transverse or even more complicated Carding arrangements are possible if special nonwoven properties should be possible or if multi-layer fiber structures be desired.

The Carrier layer of a batt is inventively means pretreated a low pressure water jet method. This will preferably carried out at pressures of up to 50 bar, particularly preferred with hole diameters of the single or multi-row arranged water jet nozzles from 70 to 120 microns and a distance from the carrier layer of 0.2 to 0.8 mm from each other.

It It has turned out that just the application of a low-pressure water jet method the characteristics of a batt for the later Application as a lining material influenced in a particularly advantageous manner. Thus, the mechanical strength of the batt is just so far increases that further handling in the production process significantly improved. On the other hand, they are characterized by this Way weakly bonded bastard still by an extraordinary soft grip, for example, for the application makes it particularly suitable as a lining material in the textile industry. Another advantage is that the batt through the solidification process be moistened automatically, so that the usual Prewetting with water to increase production safety the printing process, for example by means of padding / scooping rollers, eliminated.

in the Following the pretreatment, the carrier layer is made of batt directly in a printing machine with the dispersion containing the binder and the thermoplastic polymer comprises printed.

Preferably the mixture is for printing in the form of a dispersion.

• - And one or more adhesive mass acting as thermoplastic polymers.

The thermoplastic polymer is preferably in particulate form. It has surprisingly been found that at Printing the carrier layer with a dispersion of the particles and the binder and possibly other components, the coarser Particles to a large extent on the surface of the porous carrier material are filtered off. The coarser particles thereby accumulate on the carrier surface while part of the binder penetrates deeper into the porous Carrier material penetrates, anchored there and to a additional binding in the carrier material leads. As a result, the coarser polymer particles are in the binder matrix Although integrated, at the same time their free (upper) surface is on the surface of the carrier layer but for direct Bonding with the outer fabric available. It comes to Formation of a colon-like structure, wherein the Generation of this structure in contrast to the known double-point method but only a single procedural step is required and also Excessive vacuuming excess Powder is eliminated.

bilayer Adhesive mass points are characterized by a low adhesive mass recoil because the first applied layer acts as a barrier layer. Surprisingly also shows the colon-like binding point according to the Invention this positive feature. Obviously it comes with the method described here for an in-situ formation of a Barrier layer in the bond point, the kickback of the thermoplastic polymer is effectively braked and thereby the positive product properties strengthened.

The Size of the particles is based on the printable Area, for example, the desired size a binding point. In case of a dot pattern, the particle diameter may be between> 0 μm and 500 microns vary. Basically, the particle size of the thermoplastic polymer is not uniform but follows a distribution, d. H. you always have a particle size spectrum available. The limits given above are the respective main fractions. The particle size must be adjusted to the desired order quantity, point size and point distribution.

Farther the size of the particles is based on the Porosity of the substrate to be printed. experience from the liquid filtration show that at a particle diameter, which is about 1/3 of the average pore diameter of the carrier material is still 90% of the particles on the surface of the carrier material are filtered off. With a particle diameter in the order of half the mean pore diameter even 99% of the particles are on the support surface filtered. In practice, the usual used fibrous webs with average pore diameters of the order of magnitude of approx. 100 μm particles with particle diameters between Proven 60 μm and 200 μm. The skilled person is but it is easily possible, without inventive step under Using the above rule of thumb for a substrate with a given porosity a suitable particle size to find.

The used binders are (mixed) polymer dispersions with << 50 microns particle size. The binders used can be in their glass transition point vary, but soft products are usually "soft" binders with a Tg <10 ° C prefers. The auxiliaries serve to adjust the viscosity the paste. With suitable binders, the feel can be of the liner vary within a wide range.

in the Following the printing process, the material undergoes a thermal treatment for drying and, if appropriate, crosslinking of the binder and for and / or sintering the thermoplastic polymer together on / with the binder layer and the carrier layer surface subjected. Then the material is wound up.

A preferred application of the thermally fixable sheet is the one as a textile in the textile industry. The use of a thermally fixable sheet according to the invention however, is not limited to this application. Others too Applications are conceivable, for example as fixable textiles Fabrics for home textiles such as upholstered furniture, Reinforced seat structures, seat covers or as a fixable and stretchable textile fabric in automotive trim, shoe components or in the field Hygiene / Medical.

following The invention is without limitation of generality the example of the use of an inventive thermally fixable fabric as a fixable Einlagestoff described in the textile industry.

Used test methods:

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 n DIN 54310 respectively. DIN EN ISO 6330 , The separation forces listed are marked with "sp" if, in the release force test, the adhesion of the outer material / interlining material is so strong that, during the test procedure, the interlining material tears 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.

to Determining the adhesive mass check becomes an indoor sandwich from the insert with the outer fabric out through the Fixing press sent according to the above settings. The lower the adhesion of the inner layer, the lower it is the adhesive mass recoil.
