Abstract: The present invention provides a sound-absorbing material with excellent sound-absorbing performance and a method for manufacturing thereof. More particularly, it relates to a sound-absorbing material, which can improve sound absorption coefficient and transmission loss by forming large surface area and air layer, so as to induce viscosity loss of incident sound energy, may make light-weight design possible because it can express excellent sound-absorbing performance even using reduced amount of fiber, and can improve sound-absorbing performance by using binder fiber having rebound resilience, so as to maintain enough strength between fiber and also to maximize viscosity loss of sound energy transmitted to fiber structure; and a method for manufacturing thereof.

Abstract: 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.

Abstract: A nonwoven fabric alternately formed on its upper surface with crests and troughs extending in parallel to one another in one direction to prevent bodily fluids from staying in the crests. Short fibers 11 of thermoplastic synthetic resin are fusion bonded to one another to form a nonwoven fabric 1. The nonwoven fabric 1 is formed on its upper surface 2 with crests 6 and troughs 7 extending in parallel to one another. The crests 6 include first crests 6a having a uniform height dimension from a lower surface 3 of the nonwoven fabric 1 and second crests 6b having a uniform height dimension from a lower surface 3 of the nonwoven fabric 1 which is smaller than the height dimension of the first crests 6a. Density of the nonwoven fabric 1 gradually increases in the order of the first crests 6a, the second crests 6b and the troughs 7. The first crests 6a are formed so that the density of the first crests 6a remains lower than the density of the second crests 6b even when the first crests 6a are compressed toward the lower surface 3 until the first crests 6a becomes flush with the level of the second crests 6b.

Abstract: The invention relates to a press felt for use in the press section of a paper machine. Said felt comprises a nonwoven layer lying on one of its surfaces, the surface of said layer being connected and fixed to the felt by a thermoplastic binding material. According to the invention, the surface of the nonwoven layer is smoothed by the application of pressure from a smooth surface during the cooling of said layer surface from a temperature in excess of the melting temperature of the thermoplastic binding material to a temperature below the melting temperature. To manufacture the press felt, an untreated press felt, which contains the nonwoven layer and the thermoplastic binding agent is first produced, the thermoplastic binding agent being distributed in the nonwoven layer in the form of thermoplastic adhesive fibres and/or a thermoplastic adhesive component of bicomponent fibres. The desired press felt is produced from the untreated press felt by means of the aformentioned temperature and pressure treatment using a smooth surface, thus enabling the press felt to be simultaneously thermofixed.
