摘要:The invention relates to a method for producing a felt containing staple fibresof 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 alayer of these staple fibres to produce a bonded fibre web, forming a stacked layer ofthe bonded fibre web by feeding it to a take-off means on which the bonded fibre web islaid down so as to overlap in zig-zag folds while being taken off at the same time andentangling 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 beenapplied 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 relatesto a felt obtainable in accordance with the method, to antiballistic-shaped partsproduced from teh felt, and to antiballistic items such as fragmentproof vests, blastprotection blankets and the like which include, as a protective layer, one or more feltsaccording to the invention. The invention further relates to cut resistant cloth.
