Abstract

The invention relates to a fibrous mat facer for preparing a gypsum board, to a gypsum board comprising said mat facer and to a system comprising said gypsum board. The mat facer of the present invention shows an improved inner cohesion strength. It also exhibits lower grammage, lower thickness more air porous and higher tensile and flexural strength, thus is lighter and stronger than the known ones. It may have a certain lower surface roughness and an embossing pattern, which makes it is not only tightly bound to the gypsum core regardless of the gypsum composition and/or the presence of additives but is easier and safer handled and transported as well. The plasterboard thereof is suitable for external and internal applications. It is particular suitable for being used as external sheathing and for building or renovation material in a bathroom, a kitchen, a laundry room, and in any room that may be exposed to humidity or even in outdoor applications.

Abstract

A glazing method for improving abrasion resistance using a heated smooth roll to melt the lower-melting-point portion of bicomponent fibers as the spunbond web passes over the heated smooth roll. Because there is no external pressure exerted in a nip by an opposing second roller, as in calendering, the outer surface of the web which does not contact the heated smooth roll remains essentially unchanged and the nonwoven fabric exhibits no compression as a result of the glazing process. The roll temperature and dwell time (roll diameter, wrap angle and line speed) are controlled for the purpose of surface treating only one side of the nonwoven fabric to improve abrasion resistance while allowing the air permeability and web thickness to remain essentially unchanged.

Abstract

A glazing method for improving abrasion resistance using a heated smooth roll to melt the lower-melting-point portion of bicomponent fibers as the spunbond web passes over the heated smooth roll. Because there is no external pressure exerted in a nip by an opposing second roller, as in calendering, the outer surface of the web which does not contact the heated smooth roll remains essentially unchanged and the nonwoven fabric exhibits no compression as a result of the glazing process. The roll temperature and dwell time (roll diameter, wrap angle and line speed) are controlled for the purpose of surface treating only one side of the nonwoven fabric to improve abrasion resistance while allowing the air permeability and web thickness to remain essentially unchanged.

Abstract

The present disclosure relates generally to a nonwoven filtration media comprising a bonded mix of different, discontinuous, thermoplastic resin fibers and optionally discontinuous cellulosic fibers. In some embodiments a tackifier is added to the nonwoven filtration media to provide a sticky or adhesive surface on the fibers. The nonwoven media has an advantageous combination of stiffness, foldability, efficiency and the ability to retain a fold. The nonwoven media can be thermally bonded during the production process. The advantageous combination of mechanical properties allow the disclosed nonwoven media to accept and retain folds and pleats better than some conventional filtration materials while the mix of different fibers provides desirable filtration properties.

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 contai ning 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

The present invention relates to a method for manufacturing nonwoven and nonwoven obtainable by said method. Particularly, the invention relates to a nonwoven provided with improved tactile and absorbent characteristics, which make it suitable for use in the field of surface cleaning, personal hygiene, or formation of garments. The method is based on the use of lobed spunbonded filaments which have been treated by means of thickening means.
