Definitions

  • the present invention relates to a process for the production of elementary vegetable bast fibres.
  • Vegetable fibres are used more and more as a substitute for synthetic fibres in the non-food industry because of their advantageous technical properties, price and performance, but also for environmental and agricultural considerations.
  • Non-wood vegetable fibres are generally used in pulp production. Examples of such fibres are hemp and flax. These crops consist of two major, very distinct lignocellulosic fractions.
  • the woody core is a lignin rich, hardwood resembling material. These cores can be delignified to produce a pulp for such paper grades as printing and copying paper.
  • JP-A-63-264991 relating to the production of bast fibre pulp by cooking bast fibres with a mixture of oxalic acid or its salt, H 2 O 2 or H 2 O 2 -generating agents, alkali metal carbonates, chelating agents, and anthraquinone compounds at 60 to 130 °C.
  • the present invention relates to a process for the production of elementary vegetable bast fibres comprising the steps of
  • Fibre materials which may be used are vegetable bast fibres of lignocellulosic nature which have a lignin content between 0.3 and 10% by weight and which contain elementary fibres with a fibre length of at least 10 mm.
  • Examples of such fibres are flax, oil seed flax, hemp, ramie, milkweed and hop bast fibres. These are the principal commercial vegetable fibres.
  • flax and hemp are used because of their high cellulose content and their long ultimate fibre length. Especially preferred is flax because flax can be dew-retted more easily than hemp.
  • the raw vegetable bast fibres are subjected to a retting process before being cut.
  • Retting controlled rotting
  • the retting can be carried out in the field after harvesting (so called dew-retting for flax) or in warm water (so called warm water retting) or with enzymes.
  • step a) of the process of the invention consists of cutting the fibres to a length of 8 to 400 mm, preferably between 10 and 100 mm, depending on the intended use.
  • the purpose is to produce fibres of uniform length.
  • An example of a cutting device is a "Rotary Cutter", type 231, available from Laroche Machines Textiles, 69470 Cours, France. Any machine of similar construction may also be used.
  • Step b) of the process of the invention consists of a chemical treatment of the, optionally, retted and cut vegetable bast fibres to remove pectin and lignin compounds.
  • Step b) advantageously comprises:
  • Such a treatment is known for making pulps for paper and has been optimised for the specific objects of the present invention.
  • step i) it is also possible to eliminate step i) and to add the chelating agent to the fibres together with the oxidising agent.
  • step b) of the process of the present invention comprises:
  • Suitable chelating agents include polyamine-polycarboxylic acids, such as EDTA (ethylenediaminetetraacetic acid), N-(hydroxyethyl)ethylenediaminetriacetic acid, piperazinediacetic acid and especially DTPA (diethylenetriaminepentaacetic acid).
  • the oxidising agent is preferably H 2 O 2 , or a stabilised form thereof, but may also be a peracid, hydroperoxide, perborate etc.
  • Suitable stabilisers for H 2 O 2 include alkaline metal and alkaline earth metal silicates, phosphates and sulphates and mixtures thereof, such as a mixture of sodium silicate and magnesium sulphate. These substances can be added e.g.
  • the oven-dry weight of the fibres after cutting is measured after drying the fibres e.g. for 12 hours at 105 °C.
  • Step c) of the present process drying the cooked fibres, may be carried out in any conventional oven.
  • the fibres are left in the oven until 60-95% dryness, preferably at a temperature of 20 to 90 °C.
  • Step d) of the process consists of mechanically opening the fibres obtained in step c).
  • the device used for this may be any carding or opening device known in the art. These devices are used for cleaning cotton fibres from trashes. The aim of the use of such a mechanical opening device is to loosen the fibres obtained in the cooking step so as to form elementary fibres which have a fluffy, cotton-like appearance.
  • a mechanical opening device is a "Shirley Analyser", type SOL 102, available from Shirley International Development Ltd., Stockport, UK. Any machine of similar construction may also be used.
  • the fibres are analysed by light and electron microscopy.
  • the present application also relates to the elementary vegetable bast fibres which can be obtained by the process described above. These fibres have the following chemical properties:
  • the present invention also relates to the use of these elementary vegetable bast fibres for the production of wet or dry-laid non-woven materials as a substitute for synthetic fibres which are normally used in such materials.
  • the elementary vegetable bast fibres of the invention may also be combined with synthetic fibres in any ratio, e.g. a weight ratio of 20:80 up to 100:0
  • these vegetable fibres serve as excellent candidates for replacing synthetic fibres in non-wovens.
  • the key factors in using vegetable bast fibres are good fibre length control and high degree of fibre separation. Such properties can be obtained with the process according to the invention and therefore the elementary fibres obtained are very suitable for non-wovens.
  • the fibres of the invention also show good non-woven sheet formation and comparable sheet properties as those made with synthetic fibres.
  • the non-woven materials may be prepared by any available technique.
  • the percentages are weight to weight percentages based on the oven-dry weight of the fibres.
  • Water was added to adjust the fibre to liquor ratio to 1:5.67. These fibres were heated up to 90-95°C for 1 hour. Then the residual liquor was drained out and the cooked fibres were washed with a sufficient amount of water. These fibres were dried with hot air of 50°C. The dried fibres were then fed into a mechanical opening device, "Shirley Analyser", type SOL 102, obtainable from Shirley International Development Ltd., Stockport, UK, where the fibres were opened up. This resulted in well-separated, fluffy elementary fibres.
  • Acid insoluble lignin 1.07% Acid soluble lignin: 0.05%
  • Uronic acid 1.1%
  • Rhamnose 0%
  • Ethanol extractives 1.36%
  • Cellulose content 87.3%
  • the percentages are weight to weight percentages based on the oven-dry weight of the fibres.
  • Water was added to adjust the fibre to liquor ratio to 1:5.67. These fibres were heated to 85°C for 0.5 hour. Then the residual liquor was drained out and the cooked fibres were washed with a sufficient amount of water. These fibres were dried with hot air of 40 °C. The dried fibres were fed into a mechanical opening device, "Shirley Analyser", type SOL 102, available from Shirley International Development Ltd., Stockport, UK, where the fibres were opened up. This resulted in well-separated, fluffy elementary fibres.
  • Acid insoluble lignin 1.3% Acid soluble lignin: 0.1%
  • Uronic acid 1.7%
  • Rhamnose 0.2%
  • Ethanol extractives 1.4%
  • Cellulose content 71.9% Hemicellulose content: 10.1%
  • the percentages are weight to weight percentages based on the oven-dry weight of the fibres.
  • Water was added to adjust the fibre to liquor ratio to 1:5.67. These fibres were heated up to 100 °C for 75 minutes. Then the residual liquor was drained out and the cooked fibres were washed with a sufficient amount of water. These fibres were dried with hot air of 40 °C. The dried fibres were fed into a mechanical opening device, "Shirley Analyser", type SOL 102, obtainable from Shirley International Development Ltd., Stockport, UK, where the fibres were opened up.
