Definitions
- the invention relates to a thermally stable, melt-bond-strengthened spun-bonded nonwoven made of supporting filaments and binder filaments serving as melt binders, in which the difference in the melting points of supporting and binding filaments is less than 30 ° C.
- a nonwoven which contains crimped fibers or threads and which is consolidated by heating by means of a thermoplastic binder or thermoplastic binder fibers.
- the melting point of the binding fibers should be at least 20 ° C below the melting point of the supporting filaments. Due to the proportion of crimped fibers in this nonwoven, it is very drapable, i.e. it folds like a woven fabric; however, it is not usable as a highly resilient and dimensionally stable reinforcement material and as a tufting carrier.
- Highly resilient spunbonded nonwovens bonded with melt binders are known, for example, from DE-PS 22 40 437 and DE-A-36 42 089. These previously known spunbonded nonwovens, in which both the supporting filaments and the binder filaments can consist of polyesters, serve in particular as reinforcing and carrier materials in the manufacture of needled felt and tufting.
- filaments of a relatively coarse individual titer of more than 8 dtex are used.
- the proportion of binder filaments is 10 to 30%, preferably between 15 and 25%.
- melt binder-bonded nonwovens have the serious disadvantage that they are not suitable for those areas of application in which they are exposed to high processing temperatures, because the low melting point of the binder component also significantly reduces the processing and use temperature.
- the present invention now relates to a melt-bond-bonded nonwoven fabric with high strength and high dimensional stability, which is thermally highly resilient, ie which has an extremely advantageous high processing and use temperature.
- the melt-bonded spunbond fabric according to the invention consists of load-bearing filaments and binder filaments serving as melt binders, and is characterized in that the melting point of the binder filaments is less than 30 ° C., preferably less than 20 ° C., below the melting point of the load-bearing filaments.
- the supporting filaments and binder filaments are preferably made of polyester.
- the basis weight of the spunbonded nonwovens according to the invention is generally in the range between 50 and 500 g / m2, preferably between 50 and 250 g / m2, but can of course also be selected to be lower or higher for special applications.
- the individual titer of the supporting filaments and binder filaments is preferably in the range between 1 and 20 dtex and the proportion of the binder filaments is preferably between 5 and 25 percent by weight.
- Spunbonded fabrics according to the invention are preferred in which the individual titer of the binder filaments is smaller than that of the supporting filaments.
- Those spunbonded webs according to the invention in which the melting point of the binder filaments is 10 to 20 ° C. below the melting point of the supporting filaments are particularly preferred.
- the load-bearing filaments consist of polyethylene terephthalate
- the melt binder consists of a polymer, the melting point of which has the above-mentioned difference to the melting point of the load-bearing filaments.
- the binder filaments preferably consist of an isophthalic acid-modified polyester with a correspondingly slightly reduced melting point.
- the proportion of binder filaments in the total weight of the spunbonded nonwovens according to the invention is chosen to be as low as possible within the range given above and is adapted to the intended use of the nonwovens. Lower binder proportions further improve the thermal and mechanical properties, while higher binder proportions result in particularly delamination-resistant nonwovens.
- the weight per unit area of the nonwovens according to the invention and the individual titer of the filaments are selected within the ranges specified above, depending on the area of use. For example, a basis weight of up to 500 g / m2 and a single titer of up to 20 dtex are expediently chosen for a tufting carrier.
- the binder filaments have proven to be particularly expedient to match the type of introduction of the binder filaments and their proportion to the selected basis weight.
- those spunbonded webs according to the invention are preferred in which the supporting filaments and binder filaments consist of flame-retardant modified polyesters.
- Another preferred embodiment of the nonwovens according to the invention has a layer structure of load-bearing filaments and binder filaments, it being particularly advantageous if the two outer layers do not contain binder filaments.
- spunbonded nonwovens according to the invention are preferred, the binder filaments of which contain an antistatic, in particular carbon black.
- nonwovens according to the invention does not contain separate binder filaments but bicomponent filaments in core-shell or side-by-side arrangement, which are made up of the two polymers for the load-bearing and the binding filaments in the desired ratio.
- the spun-bonded nonwoven formed according to the invention is free from resinous binders and is therefore inherently flame-retardant.
- the low flammability can be further improved by suitable selection of flame-retardant modified raw materials for the supporting filaments and the binder filaments.
- These flame-retardant spunbonded nonwovens can then also be used in rooms at risk of fire, e.g. B. as a carrier material for curtains, wallpaper, blinds, or as components for seat covers in vehicles or aircraft.
- Particularly voluminous spunbonded nonwovens according to the invention such as those using a rel. small proportion of binder filaments and sieve drum fixation can be obtained. These then also have a loose, fibrous surface structure, which significantly increases the adhesion of coating materials, PVC or bitumen.
- Such voluminous spunbonded nonwovens with a fiber-rich surface are also suitable for producing filter fabrics.
- the addition of antistatic agents, in the simplest case of soot, in the melting cylinder moreover, permits the use of the spunbonded nonwoven according to the invention in potentially explosive areas or as a filter medium for clean rooms.
- the dyeability of the melt binder can be adapted to that of the supporting filaments by modification of the melt binder raw material; on the other hand, different dyeability can also be used to create interesting color effects.
- the spunbonded nonwoven according to the invention is produced in a manner known per se by depositing load-bearing filaments and binder filaments on a moving screen base to form a tangled nonwoven, and is characterized in that binder filaments are deposited whose melting point is less than 30 ° C., preferably less than 20 ° C. , is below the melting point of the supporting filaments.
- Load-bearing filaments and binder filaments which consist of polyester, are preferably deposited.
- the amount of filaments deposited per m2 is measured according to the criteria given above; usually 50 to 500 g of filaments are deposited per m2.
- Filament is preferably deposited using a rotating baffle plate and a downstream guide surface as described in DE-PS 27 13 241.
- the filament is deposited by a plurality of rows of depositing elements one behind the other in the direction of movement of the screen support, from which alternating load-bearing and binding filaments are deposited.
- the polymers for the supporting filaments and the binder filaments are spun out and deposited as bicomponent filaments in the specified ratio.
- the thermal consolidation is particularly preferably carried out by hot air, for example in screen drum fixers, which can be followed by a pair of embossing rollers.
- Particularly voluminous spunbonded nonwovens result from the lowest possible proportion of binder filaments and a sieve drum fixation.
