Abstract (en)
[origin: WO8912121A1] A process for treating wool with an organic solvent for an optimum contact time to improve the fibre strength whereafter said contact time said fibre strength decreases with further effluxion of time. Suitably the contact time has an upper limit of 15 minutes and a lower limit of 2-3 minutes dependent upon the sort of agitation employed in the treatment process. Preferably the solvent is selected from halogenated hydrocarbons or halogenated ethers and the treatment process also combines a separate process for minimising fibre entanglement wherein a plurality of discrete masses of animal wool fibres optionally in their original alignment and form are scoured separately from each other in a scouring medium for the minimum contact time prior to being combined as an aggregate before carding.
