A method of manufacturing a non-woven fabric, comprises: opening and mixing different input fibres to form a uniform fibre mixture having predetermined proportions of the different input fibres; carding the fibre mixture to form a uniform web of predetermined thickness travelling in a first direction; laying onto the web high tenacity yarns which extend in the first direction and are spaced apart transversely of the first direction; depositing fixed lengths of the web in alternating fashion on a conveyor travelling in a second direction transverse to the first direction to form on the conveyor a mat consisting of overlapping lengths of the web; and needle-punching the mat to form the non-woven fabric. Apparatus for performing this method of manufacture is also provided. <IMAGE> |
