Definitions

  • the present invention relates to'a process in which the albuminous substances are not incorporated with the alkaline (with caustic alkali or ammonia) cellulose solution until shortly before the latter is spun.
  • the albuminous substance ls added in the spinning tank immediately before or during the de-aeration of the spinning solution; or an aibuminous solution is intermixed continuously with the spinning solution as the latter passes from the spinning tank to the spinning machine, in which case there may be used mixing devices of known type wherein thorough mixing occurs without aeration.
  • Albumin and casein have been found to be best for the purpose in question, but there may also be used any other albuminous substance which remains in the spun thread, that is tosay, which is of sumcientl'y high molecular weight to be insoluble in the spinning bath.
  • the spun fibresc'ontaining albumin can also be after-treated with formaldehyde in order to harden the albuminous substances.
  • a viscose solution, ready for spinning, containing 7.5 per cent. of cellulose and. 6-7 per cent. of alkali is thoroughly mixed with an aqueous albumin'solution of 5 per cent. strength shortly before the spinning operation and while avoiding access of air, so that per 100 parts of cellulose there are about 10 parts of albumin; the mixture is at once spun in one of the usual spinning baths, for example, in a bath containing 13 per cent. of H2804 and 30 per cent. of NazSO4.
  • metal salts for example 0.5 per cent. of zinc sulphate
