Definitions
- the invention relates to a spunbonded nonwoven, which in the course of its Different cross-sectional contents of type A bicomponent fibers and B.
- Such a spunbonded nonwoven 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 exists from the polymer components (a1) and (a2), the latter one around 30 ° C. has a higher melting point than (a1).
- Filament type B consists of the polymer components (b1) and (b2), component (b1) being around 20 ° C. higher melting point than component (a1) and being the component (b2) a melting point which is more than 30 ° C. higher than that of component (b1) having.
- 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 provide a spunbonded nonwoven fabric made of core / sheath bicomponent filaments with a hard core and with a lower temperature to indicate as this core melting coat, the inside of which, as a result of different distribution of these filaments in the nonwoven cross section, softer or is designed to be harder than at least one of its outwardly facing ones Surfaces.
- These differences should not be reflected in a layer structure express with concrete phase boundaries to avoid the risk of delamination of the individual layers, e.g. after heat treatment during dyeing and vapors, or due to mechanical stress, e.g. when deforming, to exclude. Therefore, a very soft, flowing gradation of the Binding component concentration and thus the filament binding or adhesiveness can be generated over the cross-sectional profile of the nonwoven.
- 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.
- Filament types a, b shown as used according to the invention.
- the core is made of polyethylene terephthalate, with 2 the jacket from the binding Component called. Filaments with such cross sections and their Spinning through nozzles from the melt are known per se and not Subject of the invention.
- binding components 2 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 weight ratio of the jacket components is 2a: 2b according to the invention from 1: 3 to 1:10, in each case with the same titer of the filaments of type a and b.
- the invention relates to a spunbonded nonwoven fabric, which consists of these two Types a and b of core / sheath filaments exist and which over his Cross-sectional profile different contents of these bicomponent filaments , the content of type b filaments between 15 and 70 % By weight, based on the weight of the respective cross-sectional plane of the nonwoven.
- 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 become that softer contents of type b bicomponent filaments and more flexible nonwoven surfaces, while in extreme cases the Presence of this type of filament to 70 wt .-% an internal stability of the Nonwoven surface is achieved, which they as a carrier and stabilizer of the whole Nonwoven construction makes it suitable. These latter have nonwoven layers also a barrier function against the passage of fluid media, what Filtering applications is important; the binding jacket components of the individual filaments have flowed into one another and form one for the fluid Barrier.
- a preferred variant of the invention is that one to the outside facing surface of the spunbonded nonwoven a higher proportion of the filament Type b has and is both hard and hot-adhesive compared to the opposite surface facing the other outside, which is soft with a lower proportion of these filaments and only in interrupted ones Surface areas has hot-melt adhesive properties.
- the hot-tack ability with high proportions of type B filaments is another Advantage of the inventive design of the spunbonded nonwoven and important especially for textile applications, e.g. Stiffening inserts.
- the Cross-section of such a nonwoven fabric has a constant gradient of percentage of bicomponent filaments of type a or b and hence the hardness from one surface to another.
- the gradient towards the hard, binding component 2 is sufficient Surface prevents this when foam coating such carpets Penetration of the coating mass from the soft surface side up to 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 filaments of type b, has outer surfaces compared to its inner cross-sectional areas which are harder in this regard, since there are a larger number of bicomponent filaments b is present.
- the invention also includes a spunbond nonwoven variant in which the a relatively high bicomponent filament proportion on each of the two outwardly facing surfaces type b and therefore have a hard consistency exhibit.
- the inner cross-sectional areas are against it, with lower ones Filament b 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. Under the stretching device the spun filaments fall onto a transport device, the essential component of which is a horizontally and linearly moving catch belt 7, on the surface of which the filaments hit and to Spunbonded nonwoven.
- the spinning holes 5 serve to discharge the core / sheath filaments of type a, the spinning holes 6 the discharge of the core / sheath filaments of type b, respectively from their melting. Both types of spinning holes 5, 6 are on each spinneret plate 3 or spinning disc 4 available.
- the device is for this Purpose designed so that the projection of all spin holes 5, 6 of the inserted Spinning plates 3 or spinning disks 4 in their entirety on the Level of the collecting belt 7 the concentration curve of the filament mixture in the vertical cross section of the 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 3a of the spinning holes 5, 6 on the spinneret plate 3 leads to a spunbonded nonwoven whose one surface, which is first deposited on the belt 7 increases filaments of the Type a from the spinning holes 5 contains and is very soft.
- the collecting belt 7 facing surface higher proportions of type b bicomponent filaments from the spinning holes 6 covered.
- the other surface of the spunbonded nonwoven is created which mostly contains filaments of type b and a corresponding one Hardness and rigidity.
- a spunbonded nonwoven is created with a catch belt facing, mostly containing type b bicomponent filaments Surface created by the spinning holes 6, which in the upper in the drawing Part are arranged on the spinneret plate 3 in the plurality.
- the inner cross-sectional areas of the nonwoven are increased from type a filaments formed (middle part of the spinneret plate 3, spinning holes 5). Due to continuous, increasing depletion of type a filaments finally the second surface.
- a spunbonded nonwoven can be built up with a device according to FIG. 3c, which on the surface facing the collecting belt 7 filaments of Type a in an amount up to 85 wt .-% and in which further Cross-sectional profile up to the inside the filament portion of the Type b grows up to 70% by weight.
- Fig. 3d is considered in this context, which of 3a corresponds, with only the spinneret plate 3 here is aligned transversely to the running direction of the catch belt 7 and their The longitudinal axis corresponds to the length of the nonwoven fabric width to be produced.
- This Variant is shown again in FIG. 2a and there, above, referred to 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 filament blend within each level of the nonwoven to obtain.
- the invention can therefore on existing systems by the lowest possible Conversion measures are carried out, whether these systems for cross or Spinneret plates aligned along the direction of the collecting belt or spinning discs are designed or whether a correspondingly oblique arrangement of spinneret plates the concept of the available device underlying.
