Definitions

  • the invention relates to a method for producing a sheet from at least partially split yarns, fibers or filaments.
  • conjugated fibers From the document EP 0 814188 A is the production of easily cleavable, conjugated fibers known. These are spun by a spinning process of two primary incompatible starting materials such as polyethylene terephthalate and polyamide and can be split into their filaments by the action of mechanical forces such as a water jet treatment. From the documents JP A 1 00 96119 . JP A 2000017519 or JP A 2001181931 For example, conjugated fibers and textiles produced therefrom are known which are produced from two mutually compatible polymers in a spinning process and are split into these filaments by a splitting treatment.
  • the documents DE 100 80 786 T1 and EP A 0953660 describe textile structures which are spun from mutually compatible polymers and split by a subsequent cleavage process into fibers with a smaller cross-section. In this case, use is made of release agents at the phase boundaries of the polymers or specific etching techniques.
  • the object of the invention has been found to provide a method which simplifies the production process of fabrics made of splittable fibers, yarns or filaments, increases the degree of splitting, or which allows at least partial splitting of conjugated fibers consisting of mutually compatible polymers.
  • the object is achieved according to the preamble by yarns, fibers or filaments, which are formed from at least two filaments and originate from a common spinneret and formed into a surface image, which at a temperature between the glass transition temperature (T g ) and the melting temperature of the or the polymer used (e) are compressed to at least 10% of the density of the polymer or polymer (s) used, so that under subsequent action of further mechanical forces at least partially a splitting takes place in the filaments.
  • T g glass transition temperature
  • e melting temperature
  • conjugated yarns, fibers or filaments of mutually incompatible polymers can be almost completely split into their filaments and yarns, fibers or filaments of compatible polymers at least partially show a splitting in their filaments.
  • the method is carried out so that the compression at a temperature up to max. 10 ° C below the melting temperature of the polymer with the lowest melting temperature is made.
  • a maximum splitting result can be achieved without melting the yarns, fibers or filaments in the fabric.
  • the compression of the starting sheet is carried out by means of a roll calender.
  • This type of compression is particularly easy to integrate into a continuous manufacturing process.
  • the splitting into the filaments is carried out by means of a hydrofluidic treatment at pressures of 120-500 bar.
  • the hydrofluidic treatment at pressures of 120-500 bar depending on the composition of the conjugated yarns, fibers or filaments, results in at least partial to near complete dissociation into the filaments and entanglement and consolidation of the resultant sheet.
  • the filaments of the yarns, fibers or filaments are particularly preferably designed as microelement filaments.
  • the splitting into micro-filaments leads to fabrics with very small pores.
  • melt-spun filaments or alternatively staple fibers are used in the process according to the invention.
  • the yarns, fibers or filaments composed of at least two microelement filaments consist of mutually compatible polymers selected from the group polyethylene / polypropylene (PE / PP), polyethylene terephthalate / polybutylene terephthalate (PET / PBT), polyethylene terephthalate / polytrimethylene terephthalate (PET / PTT), polyethylene terephthalate / recycled polyester PET / R-PES), Polyethylene terephthalate / polylactate (PET / PLA), polyester / copolyester (PES / CoPES), polyamide / copolyamide (PA / CoPA), polyamide 6 / polyamide 66 (PA6 / PA66) and polyamide 6 / polyamide 12 (PA6 / PA12).

  • Recycled polyester is understood to mean, in particular, material obtained from commercial PES bottles.

  • a corresponding process is in the document FR 7420254 described and is fed by reference.
