No. 19655.—1st July, 1905.—HENRY DUNDAS MACKENZIE, of Levin, Wellington, New Zealand, Medical Practitioner. Improved method or process and apparatus for the production of fibre from flax and the like.

Extract from Specification.—This invention relates to the production of fibre from flax-blades, especially from Phormium tenax, and has for its object the production of a better quality of flax and the cheapening of the cost of manufacture. The blades are first passed through an ordinary stripper, or some analogous machine, by which the greater part of the vegetable matter is removed from the fibre, which is then washed in hot or cold water to remove as much of the vegetable matter as possible. The hanks of fibre are then placed in a tank containing a solution of one of the oxy-chlorides, by which bleaching is effected. The fibre when bleached is washed, and, for the purpose of removing any oxy-chloride or chloride which may remain in it, is placed in another tank containing an anti-chlor until all free chlorine or oxy-chloride has been removed. The fibre is then washed in running water and dried, when it is ready for the scutching operation. In apparatus which I have devised for carrying my invention into practice, oxy-chloride is produced by passing an electric current through a solution in water of common salt or other alkaline chloride. The oxy-chloride solution is led through one or a plurality of bleaching-tanks, and returned to be reacted upon by the electric current.
[NOTE.—The above extract from the specification is inserted in place of the claims.]
