Definitions

  • This invention relates to improvements in the treatment of jute fiber.
  • Jute fiber as it arrives from India is still capitaous since it has not undergone any tech nical working up process. In fact, it has only been sub ected simply to an uncontrolled maceration in the native manner. Accordingly factories are obliged to subject it to mechanical treatments with expensive 1o machinery in order to render it softer and more supple with a view to making it capable of being spun, that is to say, in order to convert it into large fabrics and sacks.
  • jute is improved and the properties thereof are modified by means of a new type of maceration.
  • the process of manufacture of this invention comprises essentially the treatment of jute with a liquid containing bacteria produced by the fermentation of flax and/or hemp.
  • This process may be carried out in the following manner At the time of maceration of flax and hemp usually in summer a quantity of the aqueous liquor is taken in which the fermentation of the said fibers is already far advanced. This liquor is charged with the well known microbes or bacteria which attack with violence in a suitable medium the pectoses and lignines adhering to the fibers.
  • a treating bath is prepared by warming water to about :2532 C. and inscminating it with a virile culture of the bacteria described above. There is added per litre of bath about 0.5 cc. of commercial potassium phosphate or body of similar nutritive properties. The bundles of jute are immersel in this bath which is maintained at 30 to 33 C. After some time bubbles of gas are seen escaping from the bath which indicates that the maceration is commencing and that be spoiled.
  • the fiber is dried until there remains only about 80% of water, then it is passed through a breaker carding machine and subsequently treated in a mercerizing bath, bleached and rendered supple by oils capable of emulsion, for example petroloum jelly, and finally dried.
  • oils capable of emulsion for example petroloum jelly
  • he fiber thus obtained is flexible, soft. white and of a beautiful brilliant and finished aspect which causes it to resemble wool.
  • WVhat I claim is 1- 1.
