Definitions

  • the invention relates to an airbag fabric made from polyamide
  • Airbag fabrics are preferably made from polyamide-based filaments, since polyamides have a good combination of strength, weight and thermal stability. Like any other thermoplastic polymer, polyamides are made from components of crude oil.
  • WO 2010/089902 A1 proposes the use of PEBA, a polyether block amide, for the production of components, e.g. in cars or
  • PEBA is also obtained at least partially from renewable raw materials.
  • decanedic acid for example has decanedic acid as an ingredient.
  • the object of the present invention is to provide an airbag fabric which consists of components which are at least partially produced from renewable raw materials and thus smaller amounts of carbon dioxide are released during production.
  • an airbag fabric made from polyamide filaments, the polyamide filaments consisting of at least 60% by weight of a bio-based monomer, based on the total weight of the polyamide.
  • Polyamides are linear polymers with regularly repeating amide bonds along the main chain. The amide bonds arise, for example, through the condensation of carboxylic acid groups with amino groups.
  • polyamides can be produced from a single type of monomer, the type of monomer having both an amino group and a carboxylic acid group (e.g.
  • Caprolactam as well as from two types of monomers, one type of monomer having two amino groups and the other type of monomer having two carboxylic acid groups. Copolymers made from the aforementioned types of monomers are also possible.
  • PA6 is the polyamide made up of a single type of monomer with an amino group and a carboxylic acid group, which has 6 carbon atoms.
  • PA6 is the polyamide made from caprolactam.
  • PA6,6 this means that the polyamide is made up of two monomers and the first number indicates how many carbon atoms the monomer with the two amino groups has and the second number indicates how many carbons the monomer has with the two carboxylic acid groups.
  • PA6,6 is a polyamide composed of hexamethylenediamine (1,6-hexanediamine) and adipic acid
  • the polyamides that make up the filaments contain bio-based monomers. This means that the monomers are obtained or manufactured from renewable raw materials. It is possible that all monomers are bio-based, or that part is bio-based and another part is bio-based
  • Monomers made from crude oil For example, in the case of a polyamide that is built up from two types of monomers, the monomer with two carboxylic acid groups is bio-based and the monomer with two amino groups is made from crude oil.
  • alkanedioic acids can be obtained from renewable raw materials using chemical, biochemical or biological processes.
  • the following is a list of the possible diacids that can be obtained from renewable raw materials:
  • Nonanedioic acid e.g. from oleic acid by ozonolysis
  • Dodecanedioic acid e.g. from coconut oil or palm kernel oil using
  • Tridecanedioic acid (e.g. from the seeds of cruciferous vegetables through ozonolysis of the contained erucic acid)
  • the corresponding diamines can be prepared by amination of the alkane diacids.
  • Raw materials are produced, less energy is used for the production of such a polyamide and less carbon dioxide is released, because here the Example the extraction of crude oil, the transport of the crude oil as well as that
  • the filaments comprise a polyamide selected from a group comprising PA4,10, PA6,10, PA8,10, or PA10,10 as well as co-polymers and / or mixtures thereof, one of the monomers in each case is bio-based.
  • the polyamides PA4,10, PA6,10 and PA10,10 have a lower density compared to PA6,6 and PA6.
  • the weight can be reduced, which reduces costs and conserves raw materials.
  • Another advantage of these polymers is that they absorb lower levels of moisture, which results in a further reduction in weight.
  • the proportion of moisture in the polymer is measured at 65% RHI (relative humidity) and a temperature of 20 ° C according to EN ISO 62: 2008-05.
  • Yarns made from PA4,10, PA6,10 and PA10,10 filaments have similar or improved properties in terms of tensile strength, elongation at break and modulus.
  • the tear strength, the elongation at break and the modulus are measured in accordance with DIN EN ISO 2062.
  • the bio-based monomer is particularly preferably decanedioic acid (sebacic acid).
  • the decanedioic acid is obtained from castor oil.
  • the advantage of decanedioic acid is that it can be obtained from renewable raw materials.
  • ricinoleic acid is obtained from the seed oil of some plant species and converted into decanedioic acid by means of alkaline cleavage.
  • castor oil contains the highest proportion of ricinoleic acid.
  • the castor oil is obtained from the seeds of the miracle tree (Ricinus communis).
  • the polyamide filament consists of at least 63% by weight, more preferably at least 70% by weight and most preferably 100% by weight of bio-based monomers, based on the total weight of the polyamide.
  • the object of the invention is also achieved by a method for producing an airbag fabric, which comprises the following steps:
  • the filaments are spun from a polyamide selected from a group comprising PA4,10, PA6,10, PA8,10, or PA10,10 as well as co-polymers and / or mixtures thereof.
  • the bio-based monomer is decanedioic acid
  • the decanedioic acid is produced from castor oil.
  • the filaments are spun from a polyamide which is at least 63% by weight, more preferably at least 70% by weight and most preferably 100% by weight
  • bio-based monomers based on the total weight of the polyamide.
  • a PA4,10 yarn is produced with a total titer of 235 dtex with a number of filaments of 36.
  • the polymer used is made from the monomers tetramethylenediamine and decanedioic acid.
  • the tetramethylenediamine was made from non-renewable raw materials and the decanedioic acid was made from castor oil.
  • the polymer thus consists of 70% by weight, based on the total weight of the polymer, of monomers that have been produced from renewable raw materials.
  • a PA6.10 yarn is produced with a total titer of 235 dtex with a number of filaments of 36.
  • the polymer used is made from the monomers flexamethylenediamine and decanedioic acid.
  • the flexamethylenediamine was made from non-renewable raw materials and the decanedioic acid was made from castor oil.
  • 63% by weight of the polymer, based on the total weight of the polymer, consists of monomers that were produced from renewable raw materials.
  • a PA10,10 yarn is produced with a total titer of 235 dtex with a number of filaments of 36.
  • the polymer used is made from the monomers decamethylenediamine and decanedioic acid.
  • the decamethylenediamine and the decanedioic acid were made from castor oil.
  • the polymer thus consists of 100% by weight, based on the total weight of the polymer, of monomers that have been produced from renewable raw materials. Comparative example 1
