Definitions

  • An object of the invention is to provide an improved method for preparing retted flax and removing chemically its gum, said method being effected with or without a final bleaching operation according to the final application intended for the ultimate thread.
  • Textile fiax fibres are well known, both as to their origin and as to the various treatments and applications thereof. With respect to said treatments, it is desired to stress the fact that flax fibres intended for treatment in spinning frames should be previously freed of dust and reduced cross-sectionally so that they may be used, after chemical treatment, on a selected spinning frame. This corresponds primarily to a physical preparation of the material, which should be effected in a very careful manner.
  • the fibres are then treated chemically in accordance with a method which forms the object of the invention, the process differing according to whether it is desired to retain the appearance, feel and colour of flax, which requires a dry treatment, or whether it is desired to remove from the fibres the pectoses and the gums binding the fibrillae to provide the fibres with suitable elastic and Water-absorbing properties.
  • Ne will describe a method for the dry treatment of the retted flax fibres, with a view to making said fibres retain their natural structure and original color, after they have been retted in a bacterial bath.
  • a container or a vat of a commercial type which may be readily heated and which is equipped with a steam input, with an input of running water and also with means for controlling the draining or exhaust of the vat.
  • the latter may have a capacity of about 2,000 litres.
  • Said bath is obtained by dissolving in water 1 gr. per litre of soda bicarbonate CO NaH and 3 grs. per litre of neutral soda carbonate CO Na The bath is heated to a temperature of 50 C. and the fibres are then immersed for 4 hours under intermittent stirring conditions.
  • the fibres are immersed in water at a temperature of 45 C. for 1 hour under intermittent stirring conditions.
  • This bath is continued for 1 hour under intermittent stirring conditions.
  • said bath constituted by running water, the temperature of which is 50 C. at the start, 1 gr. per litre of bicarbonate of soda CO Na and liquid caustic soda NaOH at 30 B. at the rate of 10 litres per 1,000 litres of water.
  • the temperature is raised during a period of 30 minutes up to C. and the fibres are left in the bath during 30 further minutes at said temperature, after which the bath is drained off.
  • the fibres are rinsed at 40 C. for 30 minutes with a mixture of 10 centilitres of formic acid and 1 litre of the aforesaid oiling product, for each kgs. of flax material to be treated.
  • the first treating operation of the fibres in a discolouring and gum-removing bath constituted by soft water may be effected in running water having at the start a temperature of 50 C. and containing 1 gr. of bicarbonate of soda (CO T-1N2.) at the rate or 1 gr. per litre and liquid caustic soda at 36 B. at the rate of 10 litres per 1,000 litres of water.
  • CO T-1N2. bicarbonate of soda
  • the seeds Before treating such green flax according to our invention, it should be subjected to the conventional cleaning i.e. the seeds should be separated from the stalks, after which a conventional stripping is performed to separate the straw from the actual fibres. Said treatment is operated in a suitable medium. The fibres are then subdivided longitudinally according to their intended application, after which they are opened by any machine which may serve for said purpose.
  • the fibres appear then in the form of flax waste, or else, as a continuous material in the shape of an untwisted cord and it is subjected to any of the above-mentioned treatments.
  • the method according to our invention is applicable to China grass and to hemp, after said materials have been suitably treated to form scurffree strips.
  • a method for preparing retted fibres comprising immersing about one part of said fibres in about twenty parts of a discoloring bath at a temperature of about 50 C. for about four hours, said bath being prepared by dissolving soda bicarbonate and neutral soda carbonate in soft water, rinsing said fibres in water at about 45 C. for about an hour with stirring, immersing said fibres in an oil bath prepared by dissolving a soluble oiling oil in formic acid, draining the oiling bath from the fibres, and drying the fibres.
  • a method for preparing retted fibres comprising immersing about one part of said fibres in about twenty parts of a discoloring bath at an initial temperature of about C., the bath being prepared by dissolving bicarbonate of soda and liquid caustic soda in soft water, raising the temperature of the bath to about C. in about thirty minutes, leaving the fibres in said bath for about another thirty minutes, draining oif said bath, treating the fibres in a bleaching bath consisting of a mixture of soft soap and liquid soda silicate to which is added peroxide of hydrogen when the mixture is boiled, treating the fibres in an oiling bath consisting of soluble oiling oil dissolved in formic acid, and washing, draining and drying the fibres.
  • a method of preparing retted fibres comprising treating one part of said fibres in about twenty parts of a discoloring bath at a temperature of at least 50 C. and then treating the fibres in an oiling bath prepared by dissolving a soluble oiling oil in formic acid.
