Definitions

  • the invention relates to a spunbonded nonwoven of continuous fibers and a method for producing such a spunbonded web.
  • continuous fibers and by the term Filaments are theoretically infinite within the scope of the invention meant long threads, from which formed the spunbonded fabric becomes. To distinguish from this are staple fibers in which they are relatively short threads, at least in the Average much shorter than the above Filaments.
  • the filaments used in the invention consist in particular of a thermoplastic material or of thermoplastic materials.
  • spunbonded nonwovens which consist in particular of monofilaments, leave something to be desired with regard to their mechanical properties, in particular with regard to the tensile strength and the work absorption (maximum tensile force work). This is especially true for spunbonded nonwovens with medium and heavy basis weights from about 30 to 40 g / m 2 . Due to the limited thermal conductivity of the plastics used, it is difficult in the thermal consolidation of these spunbonded nonwovens with higher basis weights to bring sufficient energy input into the center of the spunbonded nonwoven.
  • the invention is the technical problem of increasing the strength or tensile strength of spunbonded nonwovens with higher basis weights from 40 g / m 2 . Furthermore, the invention is the technical problem of specifying a method for producing such a spunbonded nonwoven.
  • the invention teaches a spunbonded nonwoven fabric, wherein the continuous filaments are multi-component filaments, in particular bicomponent filaments with at least one low-melting component on the outer surface, wherein it is a spunbonded thermally bonded in a calender with a stamping surface under 22%, and wherein the spunbonded fabric has a basis weight of over 40 g / m 2 .
  • Embossing surface of the calender means the effective area, the during thermal consolidation, the connection points in Spunbond or between the filaments manufactures. It So it is the area that directly adjoins the Filaments acts.
  • the embossing surface of Engraving points of the gravure roll of the calender formed. It lies within the scope of the invention that as a calender Engraving roller / smooth roller pair is used. It is located in Frame of the invention that the spunbonded in a calender with an embossing surface of at least 10%, preferably of at least 12% is thermally consolidated.
  • filaments used with titers between 1.8 - 2.5 denier are advantageously filaments used with titers between 1.8 - 2.5 denier. It can but also finer filaments can be used. in principle Therefore, it is within the scope of the invention with filaments Titers between 0.8 to 2.5 denier to use.
  • the filaments used in the invention are preferably from a low-melting component, the the outer surface of the filament is arranged and made a higher melting component, which is the core of the Filêts forms.
  • the multi-component filaments used according to the invention in particular bicomponent filaments a core-shell structure on and forms the low melting component of the coat.
  • the at least one higher Melting component forms the core of the filament. It is within the scope of the invention that at a Filament with core-shell structure of the core completely of surrounded by the sheath of the low-melting component is. Moreover, it is within the scope of the invention that both the core and the coat over the entire length a filament extends.
  • the low melting component has a melting point, the at least 5 ° C, preferably at least 10 ° C and very preferably at least 15 ° C lower than that Melting point of the higher melting component.
  • the melting point is low melting component at least 20 ° C lower than that Melting point of the higher melting component.
  • the melting point of the low-melting Component is at 120 ° C and higher.
  • the low-melting Component is a polyolefin or a mixture of Polyolefins and their copolymers. According to one Embodiment of the invention is in the low-melting component to polyethylene and in the higher melting component to polypropylene.
  • Polyethylene in the context of a core-shell structure so the Coat and polypropylene the core of the filament.
  • a Core-shell structure realized, wherein the polypropylene copolymer the jacket and the polypropylene the core of the Fil noirs forms.
  • the polypropylene copolymer it is preferably a polypropylene-polyethylene copolymer. This copolymer can be heterophasic be.
  • heterophasic polypropylene-polyethylene copolymers preferably polyethylene contents of 2 to 6 Wt .-% included.
  • polypropylene copolymer may instead of the polypropylene copolymer also Polypropylene terpolymer as low-melting component be used, which is preferably a Polypropylene-polyethylene-polybutylene terpolymer.
  • polyethylene or polypropylene be used and as higher melting Component of a polyester can be used.
  • At a preferred core-shell structure forms the polyethylene or polypropylene the jacket and the polyester the core.
  • the proportion of low-melting component in the filaments 10 to 40 wt .-%, preferably 15 to 35 wt .-% is. there are the percentages by weight on the entire filament based.
  • the proportion of the higher melting component Accordingly, it is preferably 90 to 60% by weight, preferably 85 to 65 wt .-%.
  • the spunbonded nonwoven fabric according to the invention is expediently a spunbonded nonwoven thermally consolidated in a calender with an embossing area of less than 20%.
  • the spunbonded nonwoven has a basis weight of about 50g / m 2, preferably of more than 60g / m 2.
  • the invention further teaches a method for producing a spunbonded nonwoven fabric, wherein a nonwoven web is formed from continuous fibers formed as multicomponent filaments, in particular as bicomponent filaments, which filaments have a low-melting component on their outer surface, wherein the nonwoven web is thermally solidified in a calender with an emboss area less than 22% and wherein a spunbonded fabric having a basis weight of over 40g / m 2 is produced.
  • connection points means in the frame the invention, the areas of the filaments due to the Exposure of the calender are softened and where Connecting points formed with adjacent filaments become.
  • Connecting points formed with adjacent filaments become.
  • the connection points only the outer areas of a Filaments in relation to the cross section of the filament softens and a core area is not softened or remains free of softening. This possibility offers itself especially when the melting point difference with respect to low-melting and higher-melting component is relatively high, so for example in a polyolefin as a low-melting component and a polyester as a higher melting component.
  • the invention is based on the finding that due to the inventive design of the spunbonded fabric or the filaments of the spunbonded fabric in the thermal consolidation of the energy input in the middle of the nonwoven sufficient to connect the filaments on the low-melting outer material. On the other hand, a disadvantageous heat deterioration of the remaining filament areas does not take place.
  • the spunbonded nonwoven according to the invention is distinguished by a surprisingly high strength or tensile strength. It can spunbonded webs with highêth facilitateen of about 40g / m 2, particularly about 50g / m 2 and especially about 60 g / m 2 are produced, which have such a surprisingly high strength or tensile strength.
