ABSTRACT:
A fibre and method of making the fibre. The fibre consists at least in part of a cationic amino-formaldehyde resin and may also include a carrier material which is a water-soluble fibre-forming polymer.
Fibres can be made by a wet-spinning method. An aqueous solution of the resin is mixed with an aqueous solution of polyvinyl alcohol to form a spinning solution and the spinning solution is extruded into a coagulation bath to form a fibre, which is dried and cured.
The cationic amino-formaldehyde resin comprises the reaction product of a triazine, optionally urea, and formaldehyde and a compound, such as di- or tri-ethanolamine to render the resin cationic. It may be mixed with another cationic amino-formaldehyde resin, e.g. a cationic urea-formaldehyde resin, in the making of the fibre.
