ABSTRACT:
The invention concerns a hydrophilic cotton fleece made by a method of manufacture characterized in that during the operations of boiling and bleaching in an autoclave, treatment liquids are made to circulate radially through the turns of a coil in such a manner that a differential pressure is established between the liquid entering the coil and a liquid leaving the coil as a result of load losses due to the difficulty which the liquid experiences in passing through the coil, the resulting cotton fleece exhibiting improved cohesion, resistance to tearing and absorption properties.
