Abstract: Methods for manufacturing nonwovens and nonwovens obtained by such methods are provided. Particularly, nonwovens are provided with improved tactile and absorbent characteristics, which make them suitable for use in the field of surface cleaning, personal hygiene, or formation of garments. The methods are based on the use of lobed spunbonded filaments which have been treated by a thickening apparatus.

Abstract: The present invention relates to a process and equipment for manufacturing a non-woven fabric provided with optimum softness and resistance characteristics, as well as attractive appearance. Particularly, the invention relates to a process and equipment for manufacturing non-woven fabrics (NWF) both of the spun-lace type, either spunbonded and carded (hydro-entangled NWF), and the non-woven fabrics thereby obtained by means of hydro-embossing and thermo-embossing treatments.
Abstract: Disclosed herein is a reflectively patterned, fibrous, sided nonwoven material comprising a first set of fibers hydraulically needled with a web of a second set of fibers, the first set of fibers primarily containing short fibers and the second set of fibers primarily containing one of (a) substantially continuous filaments, (b) long fibers, and (c) short fibers having an average fiber length at least twice the average fiber length of the first set of fibers. The material has a first surface predominately comprising the first set of fibers and an opposing second surface predominately comprising the second set of fibers. A method of patterning a sided nonwoven web and a reflectively patterned, sided nonwoven material also are disclosed.
Abstract: Fibrous support intended to be impregnated, the fibers of which are formed 100% of cellulose fibers, characterized in that it presents, before creping or embossing, a wet traction strength of over 2.4 N/15 mm in the cross-machine direction, a water absorption capacity of at least 300% and contains less than 2% dry wet strength 10 agent in comparison with the dry weight of the fibers.

Abstract: The present invention relates to a process and equipment (1) for creating prints on non-woven-fabric and, particularly, relates to a process and to equipment (1) which allows the creation of color prints on non-woven fabrics at high speed while at the same time maintaining optimal print quality on wet or dry product, either in-line with production or off-line. The NWF may be printed over only a small percentage with respect to its surface (2-3%) up to a coverage of 100% of its surface, depending on the use of the NWF itself, i.e.: personal hygiene, domestic hygiene, matting, non-woven fabric for clothing, table-cloths, handkerchiefs, curtains (furnishings), bags, containers for items.
