Abstract

Fibre fleeces are made by dispersing in water a plurality of synthetic fibres, adding to the dispersion 0.01 to 0.001% by weight, calculated on the weight of dispersion liquid of carboxy-methycellulose, casting the dispersion and dehydrating and drying the fleece formed. The fibres have smooth surfaces, and are of such a form that flat surfaces are available for the contact of the fibres with one another. The carboxymethylcellulose has a viscosity of more than 6cP in 0.2% aqueous solution at 20 DEG C. In the examples, ribbon-like fibres of polyethylene terephthalate or polycaprolactan, obtained by melt-spinning through a nozzle of elongated aperture are dispersed in water to a concentration of 0.05%. Enough carboxymethylcellulose was added to give a concentration of 0.004% by weight, and the slurry cast on a draining screen and processed on a conventional paper-making machine.
