The invention relates to a method for producing a felt containing staple fibres of ultra-highly oriented polyethylene having an intrinsic viscosity (in decalin at 135 DEG C) of at least 5 dl/g, comprising the steps of opening up a mass of staple fibres, carding a layer of these staple fibres to produce a bonded fibre web, forming a stacked layer of the bonded fibre web by feeding it to a take-off means on which the bonded fibre web is laid down so as to overlap in zig-zag folds while being taken off at the same time and entangling the stacked layer to produce the felt. The felt has an improved strength, contexture and specific energy absorption (SEA), as a result of an antistatic having been applied to the staple fibres and the opening up and carding taking place at a relative humidity of at least 60 % at a temperature of at least 20 DEG C. The invention also relates to a felt obtainable in accordance with the method, to antiballistic-shaped parts produced from teh felt, and to antiballistic items such as fragmentproof vests, blast protection blankets and the like which include, as a protective layer, one or more felts according to the invention. The invention further relates to cut resistant cloth. |
