International Classification:

D21H 2122

US Classification:

162127, 162135, 162158, 1621681, 1621682, 1621683, 162179, 1621811, 1621812, 162109, 162111, 162112, 162113, 162134

Abstract:

Disclosed is a composition for softening an absorbent tissue and tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; a bilayer disrupter and a high polymer. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. The high polymer adds âstringinessâ to the composition opening the air pressure operating window for spray application of the softening composition. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: the vehicle is water, the electrolyte is calcium chloride, the bilayer disrupter is a nonionic surfactant, and the high molecular weight polymer is a nonionic polyacrylamide.

US Classification:

127 29, 536102, 523 1, 523220, 524 47, 428373

Abstract:

The present invention relates to a starch composition comprising starch, a polymer that is substantially compatible with starch and has a weight-average molecular weight of at least 500,000 such that the polymer forms effective entanglements or associations with neighboring starch molecules, and preferably at least one additive to improve melt flow and melt processability. The additive may be a hydroxyl plasticizer, a hydroxyl-free plasticizer, a diluent, or mixtures thereof. The composition is melt processable on conventional thermoplastic equipment. The composition is especially suitable for uniaxial and biaxial extensional processes to make fibers, films, foams and like products.

Abstract:

Non-thermoplastic starch fibers having no melting point and having apparent peak wet tensile stress greater than about 0. 2 MegaPascals (MPa). The fibers can be manufactured from a composition comprising a modified starch and a cross-linking agent. The composition can have a shear viscosity from about 1 PascalÂSeconds to about 80 PascalÂSeconds and an apparent extensional viscosity in the range of from about 150 PascalÂSeconds to about 13,000 PascalÂSeconds. The composition can comprise from about 50% to about 75% by weight of a modified starch; from about 0. 1% to about 10% by weight of an aldehyde cross-linking agent; and from about 25% to about 50% by weight of water. Prior to cross-linking, the modified starch can have a weight average molecular weight greater than about 100,000 g/mol.

US Classification:

428370, 428373, 428374, 428372

Abstract:

The present invention is directed to multicomponent fibers. The fibers may be in a side-by-side, sheath-core, segmented pie, islands-in-the-sea configuration, or any combination of configurations. Each component of the fiber will comprise destructurized starch and/or a thermoplastic polymer. The present invention is also directed to nonwoven webs and disposable articles comprising the multicomponent fibers. The nonwoven webs may also contain other synthetic or natural fibers blended with the multicomponent fibers of the present invention.

Abstract:

A process for making non-thermoplastic starch fibers comprises the steps of: (a) providing a non-thermoplastic starch composition comprising from about 50% to about 75% by weight of modified starch and from about 25% to about 50% of water and having a shear viscosity within the at least one nozzle from about 1 to about 80 Pascals-second at the processing temperature and at a shear rate of 3,000 sec ; (b) extruding the non-thermoplastic starch composition through at least one extrusion nozzle terminating with a nozzle tip, thereby forming at least one embryonic starch fiber; (c) attenuating the at least one embryonic starch fiber with an attenuating air having an average velocity at the nozzle tip greater than about 30 meters per second, to cause the fiber to form an average equivalent diameter of less than about 20 microns; (d) dewatering the at least one embryonic starch fiber to a consistency of from about 70% to about 99% by weight, thereby producing at least one non-thermoplastic starch fiber, wherein the starch fiber as a whole has no melting point.
