Support in nonwoven textile reinforced with threads and process for making such support

摘要

The present invention relates to a support in non-woven textile reinforced with threads comprising at least two webs of nonwoven spunbond and a plurality of reinforcement threads which are positioned between the two webs of nonwoven with an overall orientation parallel to a longitudinal direction X. The webs and the threads are solidarized to each other by needling, by means of resining through the application of chemical bonding agents and by heat bonding with application of heat bonding fibres. According to the invention, the reinforcement threads are associated with the webs and are subjected to solidarization together with said webs without applying to the threads and to the webs a tension along said longitudinal direction. This way during the assembly and solidarization steps with the webs, the reinforcement threads are free to move and to misalign locally in relation to the longitudinal direction. The support has the reinforcement threads blocked in the final position assumed in relation to said webs by chemical bonding agents and/or by the heat bonding fibres.
