Definitions

  • the invention relates to a spunbonded nonwoven, which in the course of its Cross-section has different contents of bicomponent filaments.
  • the remaining filaments are polyethylene terephthalate monofilaments.
  • Such a Spunbonded nonwoven fabric is known as a material from JP-A-Patent 435 28 61 for sacks:
  • the spunbonded non-woven fabric consists of two types A and B of long, conjugated Multi-component filaments.
  • Filament type A consists of the polymer components (a1) and (a2), the latter having a melting point which is 30 ° C. higher than (a1).
  • Filament type B consists of the polymer components (b1) and (b2), component (b1) having a melting point which is 20 ° C. higher than component (a1) and wherein component (b2) has a more than 30 ° C higher melting point than component (b1).
  • the nonwoven also has a four-layer structure in cross section, wherein the individual layers differ in that the first only filaments of type A, the second and third layers contain filament types A and B with a higher proportion of A in the second and a higher proportion filament type B in the third layer, while the fourth Layer consists only of type B filaments.
  • the object of the invention is to produce a spunbonded nonwoven made of mono- and bicomponent filaments indicate its interior, due to the different Distribution of these filaments in the non-woven cross-section, softer or harder is as at least one of its outward-facing surfaces. These differences should not be reflected in a layer structure with concrete Express phase boundaries to reduce the risk of delamination of the individual layers, e.g. after heat treatment during dyeing and steaming, or due to mechanical stress, e.g. when deforming.
  • the invention further relates to a for producing such a spunbonded nonwoven suitable device which, in contrast to the prior art Technology where several separate process steps for Manufacture and required to connect the individual layers of the nonwoven and each of these stages is a separate, customized arrangement of Has spinneret bars, a single device with correspondingly arranged Spinneret beam is sufficient, and this arrangement of those on conventional devices for the production of monofilaments equal.
  • Fig. 1 is considered.
  • Three variants a, b, and c are shown there by way of example for cross sections of bicomponent filaments as are used according to the invention.
  • the filament matrix made of polyethylene terephthalate is denoted by 1, and 2 each denotes an outward-pointing segment from the binding component. Filaments with such cross sections and their spinning through nozzles from the melt are known per se and are not the subject of the invention. Under Segments "should be understood here to mean a regularly or irregularly shaped enrichment of the binding component on the outer surface of a polyethylene terephthalate core filament of any cross-section.
  • adhesive components are copolymers of terephthalic acid or dimethyl terephthalate, isophthalic acid, adipic acid, ethylene glycol, butanediol, and homopolymers such as polybutylene terephthalate, polyamides and polyolefins the homologous range from polyethylene to polybutylene.
  • the invention relates to a spunbonded nonwoven fabric, which consists of mono- and Bicomponent filaments exist and which over its cross-sectional course has different contents of bicomponent filaments, where these contents between 1 and 100 wt .-%, based on the weight of each selected cross-sectional plane of the nonwoven.
  • the monofilaments which may be present consist of polyethylene terephthalate, the bicomponent filaments made of a core made of polyethylene terephthalate, which comprises the mentioned, outwardly facing segments 2 of the binding component.
  • Essential to the invention is in particular that the cross-sectional planes of the spunbonded nonwoven, which have different proportions on bicomponent filaments, sliding with respect to these contents, without recognizable phase boundaries, merge into one another. Hence delamination of adjacent nonwoven layers with different filament compositions almost impossible.
  • the invention allows a large number of percentage metering of the filaments in the individual cross-sectional planes.
  • a large number of spunbonded nonwovens can thus be produced, and basis weights of 10 to 500 g / m 2 can be produced as desired.
  • the rule must be observed be that low levels of bicomponent filaments to softer and lead to more flexible nonwoven surfaces, while in extreme cases the exclusive The presence of these filaments ensures an internal stability of the nonwoven surface is achieved, which they as a carrier and stabilizer of the entire nonwoven structure makes suitable. These latter have nonwoven layers also a barrier function against the passage of fluid media, what for filter applications is important.
  • a preferred variant of the invention is that one to the outside facing surface of the spunbonded nonwoven has a higher bicomponent filament content possesses and is both hard and hot-adhesive compared to the opposite surface facing the other outside, which is softer with a lower bicomponent filament content and has no hot-melt adhesive properties.
  • This hot tack at high Bicomponent filament proportions is another advantage of the invention Design of the spunbonded nonwoven and important especially for textiles Applications such as Stiffening inserts.
  • the cross section of such Nonwoven has a constant gradient of the percentage on bicomponent filaments and thus also the hardness of one surface to the other.
  • the gradient in the direction of the hard surface rich in bicomponent fibers prevents streaking when foaming such carpets the coating mass from the soft surface side up to the pile fibers. This gradient also indirectly controls the tear resistance of the finished carpet.
  • the voluminous and soft nonwoven side promotes the good one Pimples and thus anchoring of the carpet fibers in the nonwoven cross section when tufting.
  • the tufting needles can be inserted into the nonwoven fabric from the hard side penetrate without loosened fibers from it in the needles and disrupt the tufted image.
  • the fourth advantage for the application for tufted carpets is that in is able to with low carpet fiber weights (pile weights) and carpet fiber lengths (Pole heights) to work without changing the surface image (Pole image) through fibers detached from the nonwoven composite is caused.
  • Another preferred embodiment of the invention relates to a spunbonded nonwoven, which has two soft, few bicomponent filaments, has outer surfaces compared to its inner cross-sectional areas which are harder in this regard, since there is a larger one Number of bicomponent filaments is present.
  • the invention also includes a spunbond nonwoven variant in which the a high proportion of bicomponent filament on both surfaces facing outwards possess and thus have a hard consistency.
  • the inner cross-sectional areas are against it, with lower bicomponent filament proportions, very soft.
  • the invention also relates to a device for producing the first product claim characterized spunbonded nonwoven.
  • this device has one to forty rectangular spinneret plate (s) 3 or round spinning disc (s) 4, which over a conventional stretching device (not shown) for the Spinning holes 5, 6 leaving filaments is (are) arranged. Below the Stretching device, the spun filaments fall onto a transport device, whose essential component is a horizontally and linearly moving Catch tape 7 is, on the surface of which the filaments hit and to Spunbonded nonwoven.
  • a transport device whose essential component is a horizontally and linearly moving Catch tape 7 is, on the surface of which the filaments hit and to Spunbonded nonwoven.
  • the spinning holes 6 serve to discharge the monofilaments, the spinning holes 5 the discharge of the bicomponent filaments, each from their melt. Both Spinning hole types 5, 6 are on each spinneret plate 3 or spinning disc 4 available.
  • the device is designed such that the projection of all spin holes 5, 6 of the spin plates 3 or Spinning disks 4 in their entirety to the level of the fall arrester 7 Concentration course of the filament mixture in the vertical cross section of the Nonwoven corresponds. Seen in the direction of the movement of the catch belt 7, so hit those filaments or that filament blend first on which one of the outer surfaces of the to be manufactured Form nonwoven. Then arrive in the smooth transition from the first filed type and blend of filaments covering the inner areas the filaments or blends forming the nonwoven to be deposited until the very end hit those filaments on the belt 7 which are the second surface of the spunbonded nonwoven.
  • FIG. 3 shows three in the upper half with their Longitudinal axis arranged parallel to the running direction of the collecting belt 7 rectangular spinneret plates 3.
  • the arrangement a of the spinning holes 5, 6 on the spinneret plate 3 leads to a spunbonded nonwoven whose one surface, which is first placed on the belt 7, is very soft and exclusive Contains monofilaments from the spinning holes 6.
  • the collecting belt 7 facing surface higher proportions of bicomponent filaments from the spinning holes 5 covered until the other surface of the Nonwoven fabric is deposited, which is made entirely of bicomponent filaments Spinning holes 5 exists and thus a higher hardness and rigidity than that first generated area and the property of hot-melt adhesive properties.
  • spinneret plates 3 are used according to variant b in Fig. 3, a spunbonded nonwoven with a Collection belt facing exclusively containing bicomponent filaments Surface created by the spinning holes 5, which in the drawing the upper part on the spinneret plate 3 are arranged.
  • the inner cross-sectional areas of the Nonwoven fabric formed from the monofilaments alone (middle part of the spinneret plate 3, spinning holes 6).
  • a spunbonded non-woven fabric can be built up on the Collection surface 7 facing surface almost exclusively monofilaments contains and in which in the further cross-sectional course to the inside the bicomponent filament content is continuously growing up to 100%.
  • the one Harness 7 facing away from the nonwoven surface is then exclusive again formed from monofilaments.
  • variant d which of variant a corresponds, with only the spinneret plate 3 transverse to the direction of the Harness 7 is aligned and its longitudinal axis is the length of the generating nonwoven width corresponds.
  • This variant is again in Fig. 2a shown and designated as a3.
  • FIG. 2b Another variant of the device looks obliquely to the transport direction of the Harness 7, staggered in a row parallel to its level arranged, rectangular spinneret plates 3, as in two variants b1 and b2 is shown in Fig. 2b. With this graduation they are also the ones Spinning holes 5, 6 leaving filaments transversely to their direction of fall and transversely to lead to the running direction of the collecting belt 7 pivoting through air currents, to maintain a constant blend of fibers within each level of the nonwoven to obtain.
