Definitions
- This invention relates to a method of manufacturing a fibre material coated with atomized particles of active carbon.
- a fibre material coated with atomized particles of active carbon is used as absorption material , for exanple, in gas masks, protective clothing, at waste disposal and, above all, in bandages.
- absorption material for exanple, in gas masks, protective clothing, at waste disposal and, above all, in bandages.
- the material absorbs bacteria and odours from infected wounds and assists in a rapid healing of the wound.
- Active carbon is well-known as absorption material and is since long used in many different connections. In certain connections, however, it is an advantage if the active carbon could be available in sheet fom.Progosals have been made earlier to produce such sheet form.
- One proposal implies that a normal rayon fabric is exposed to an atmosphere of carbon dioxide at an increased temperature of about 300oC, whereafter a partial carbonizationn of the fabric is brought about by heating to about 900oC. This method, however, is time-consuming and expensive, and the resulting properties of the material did not satisfy the expectations.
- fibre material coated with active carbon has been proposed to manufacture a fibre material coated with active carbon by a method in aqueous solution.
- fibre material have been used cotton and asbestos, which were disintegrated in water and to which atomized carbon was added at heavy stirring.
- the atomized active carbon is applied on a fibre material in aqueous suspension by adding a tenside to the suspension.
- active carbon in sheet form is produced in that the atomized carbon is applied on cellulose fibres in suspension, and that thereafter sheets are formed of the suspension.
- the amount of carbon contained in the carbon - cellulose pulp mixture is 1-65%.
- the amount of added tenside should be so that the tenside concentration in the fibre suspension is 10 -7 - 10 -1 %.
- Suitable tensides have proved to bequarternary ammonium compounds based on dinonylphonol,for example Berocell 564.
- a certain amount of the material was shaken in a solution of methylene blue, the material was filtered off, and the colour depth of the solution was measured in a spectrophotometer.
