Definitions

  • the present invention relates to a process for making fibres from the hair of an animal, e.g. a rabbit, and in particular from Angora rabbit hair.
  • the hair fibres obtained from Angora rabbits do not have natural curls or crimps such as those of a fleece of wool, and in order to provide curls or crimps therein such Angora rabbit hair fibre has to be treated in an alkaline solution.
  • the hair fibre which is treated only in an alkaline solution is liable to be brittle and lustreless, and also has an intensity or strength less than that of the untreated, fresh hair fibre. It is therefore difficult to spin yarn out of such hair fibre that has been treated only in an alkaline solution.
  • animal hair e.g. hair obtained from Angora rabbit
  • a diluted acid solution containing hydrogen peroxide e.g. hair obtained from Angora rabbit
  • a weak alkaline solution e.g. water containing hydrogen peroxide
  • the hair fibre is treated in a diluted acid solution containing hydrogen peroxide and subsequently in a weak alkaline solution to cause the hair fibre to adopt a curled or crimped appearance.
  • Angora rabbit hair obtained from Angora rabbits is put in a diluted acid solution containing hydrogen peroxide heated to temperatures of the order of 70 to 80° and agitated for 15 to 30 minutes, in order to bleach and sterilize the rabbit hair. Then the Angora rabbit hair is washed with water several times in a water tank and dehydrated in a dehydrator for say, 15 to 25 minutes. The Angora rabbit hair thus treated is then immersed for, say, 5 to 12 minutes in 0.5 to 3% weak alkaline solution comprising sodium carbonate or urea in order to neutralize the remaining acid ingredient of the rabbit hair and cause the hair fibre to be provided with curls or crimps.
  • the Angora rabbit hair is then again washed in water several times and dehydrated sufficiently in a water tank. Finally the treated Angora rabbit hair is dried by heating in a drying oven or by utilising the heat of the sun's rays, resulting in bright and lustrous hair fibre having curls or crimps and an intensity or strength closely approaching that obtainable from a wool fleece.
  • the thus treated hair fibre can be carded in a card machine and be turned into spinning yarn. Furthermore, since the resultant hair fibre is white and bright (or lustrous), it is possible to dye the hair fibre before and/or after spinning or weaving.
  • one embodiment of the invention comprises, essentially, the process steps of:
  • Angora rabbit hair obtained from Angora rabbits is immersed in a bath of diluted acid solution containing hydrogen peroxide, and the solution in heated to temperatures of the order of 70 to 80°.
  • the diluted acid solution may be 1.5-2% diluted sulphuric acid-solution, and 35% by weight of hydrogen peroxide, in relation to the above diluted acid solution, being added.
  • the Angora rabbit hair immersed in the diluted acid solution containing hydrogen peroxide is agitated for 15-30 minutes in order to each an sterilize the hair. Then, the Angora rabbit hair is removed from the bath and is washed with clean water in a water tank several times and dehydrated in a dehydrator for 15 to 25 minutes.
  • the Angora rabbit hair is treated in a second bath containing weak alkaline solution in order to neutralize any acid ingredient still remaining in or on the rabbit hair and to provide the hair with curls or crimps.
  • the weak alkaline solution may be a 0.5-3% solution of sodium carbonate or urea.
  • the Angora rabbit hair is immersed in the solution for 5 to 12 minutes. After removal of the Angora rabbit hair from this second bath it is washed with water in a cleansing tank several times and dehydrated in a dehydrator.
  • the dehydrated Angora rabbit hair is then dried by heating in a drying oven at 60-80° or alternatively is dried by utilizing the heat of the sun's rays.
  • the resultant hair fibre is white, bright and lustrous and has curls or crimps suitable for spinning the hair and an intensity or strength approaching that obtainable from a wool fleece.
  • This resultant hair fibre is then carded in a card machine to provide the bulky fibric characteristics for spinning yarn. Since the resultant hair fibre is white and bright, it is possible to dye the hair fibre before and/or after spinning or weaving.
