ABSTRACT:
A method of forming a non-woven material includes blending both synthetic and wool fibres in a web and stabilizing the web by utilizing a bonding medium to form dispersed bonds between the fibres. The wool fibres are subjected before formation of the web to a pretreatment effective to modify the epicuticle of the wool so as to substantially increase the surface energy of the wool fibres without destroying their integrity to an extent sufficient for the wool fibres to accept the bonding medium in the web. The dispersed bonds thereby include bonds with wool fibres substantially effective to hold the wool fibres of the material in the web.
