Abstract: A continuous filament spun-laid web includes a plurality of polymer fibers within the web, the web having a first thickness and the web being free of any thermal or mechanical bonding treatment. Activation of the web results in at least one of an increase from the first thickness prior to activation to a second thickness post activation in which the second thickness is at least about two times greater than the first thickness, a decrease in density of the web post activation in relation to a density of the web prior to activation, the web being configured to withstand an elastic elongation from about 10% to about 350% in at least one of a machine direction (MD) of the web and a cross-direction (CD) of the web, and the web having a tensile strength from about 50 gram-force/cm2 to about 5000 gram-force/cm2.

Abstract: Fibers of diverse materials find widespread use in inorganic binder compositions to improve the properties of the final cured composite materials. When using high amounts of fiber in inorganic binder slurries, problems arise due to the loss of workability because of unevenly distributed fiber content. The novel fibers according to the invention allow the use of large amounts of fiber without loss of workability and are particularly useful to control the rheology of the composite slurry mixtures.

Abstract: A biodegradable, substantially continuous filament is provided. The filament contains a first component formed from at least one high melting polyester and a second component formed from at least one low melting polyester. The low melting point polyester is an aliphatic-aromatic copolyester formed by melt blending a polymer and an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in the formation of substantially continuous filaments.
