Abstract
1297405 Non-woven felt EDWARD W ANDREW Ltd 21 April 1971 [8 May 1970] 22228/ 70 Heading D1R In a process for making a non-woven felt consisting wholly or partly of high shrink and heat-shrinkable fibres, the felt is substantially prevented from shrinking along its length and width during the application of heat. In the described process a batt 12 of shrinkable fibres is passed twice between a heated rotating bowl 10 and a moving web 14 so as to subject both batt surfaces to bowl heat, the batt being restrained so as to shrink only in thickness. The batt may be needled before heating. The production of non-woven felt from batts of polyester fibre is exemplified. To form a filter, the matt may be needled before heating to a layer of fibres of coarser denier than the high-shrink fibres.
