Definitions

  • the fibres of synthetic linear polymers such as the polyamides and the highly polymeric polymethylene terephthalates are made by cutting or breaking continuous filaments, usually when they are in the form of a tow. These fibres are then formed into spun yarns by any known method.
  • the highly polymeric polymethylene terephthalates such as polyethylene terephthalate can be treated to reduce the molecular weight of the filaments or fibres using known polymer degradation techniques, such as superheated steam.
  • Another method comprises an amidation treatment using aqueous solutions of ammonia, ammonia vapour or amines.
  • Other suitable methods comprise treatments with concentrated nitric acid or sulphide solutions, such as sodium sulphide. A variety of such procedures are described in the literature, and no limitation to the specific agents list is intended.
  • the treatment should be applied uniformly. This may be achieved by reducing gradients of temperature and moisture in the treating zone to a minimum. In some treatments the reduction of the molecular weight of the polymer may be accompanied by a chemical change, e.g. the treatment of polyethylene terephthalate with ammonia, which is thought to result in amidation.
  • Extension at break was reduced from 27.0% on the untreated sample to 26.3v and 16.4, after treating for 18 and 42 hours, respectively, whereas the intrinsic viscosity was reduced from 0.56 on the untreated sample to 0.45 and.0.35 respectively, which corresponds to a'number average molecular weight of 9,750 on the untreated sample and 7,250 and 5,000 after treatment for 18 and 42 hours.
  • the corresponding relative viscosities as measured at 25 C. in a 10% weight/volume solution in a mixture of 10' parts of phenol and 7 parts 2,4,6-trichlorophenol (by weight) are 16 and 11.
  • the abrasion resistance was reduced from 22,000 revolutions of the abrasion tester to 14,500 and 6,000 revolutions after the treat ment for 18 and 42 hours, respectively.
  • the number of pills per square inch was 12.5 in the untreated sample and no pilling occurred on a comparative test after the samples had been treated for 18 to 42 hours.
