Abstract: Provided is a conjugate fiber for air-laid nonwoven fabric manufacture having a planar zig-zag crimp shape before a thermal treatment, such that a uniform web is obtained by air laying with high processability and productivity, and the conjugate fiber develops a spiral crimp when the web is subjected to a thermal treatment to thereby enable the web to shrink significantly, as a result of which a nonwoven fabric can be obtained in which fibers are amassed to a high density. The conjugate fiber for air-laid nonwoven fabric manufacture is a heat-fusible conjugate fiber in which a first component comprising an olefinic thermoplastic resin is conjugated with a second component comprising an olefinic thermoplastic resin having a melting point higher than that of the first component.

Abstract: An aqueous binder composition for use in making fiber mats comprising as a major component a thermosetting urea-formaldehyde resin and as a minor component a water-soluble additive is at least one styrene/acrylate solution polymer having a bi-modal molecular weight and comprising a first molecular weight species and a second molecular weight species.
Abstract: A textile benefit composition comprising a polyurethane and/or a polyurethane co-polymer; a cross-linking agent; a catalyst; and a carrier and processes for making and using the aforementioned compositions and textiles treated with such compositions are disclosed.
Abstract: A process for making a fibrous product using a binder based on a formaldehyde-containing resin and especially for making fiberglass insulation products, and to the fibrous products themselves, wherein the fibrous product has a backing sheet affixed thereto and the backing sheet is coated or impregnated with a formaldehyde scavenger composition, with the result that the fibrous products exhibit a reduced level of formaldehyde emission.

Abstract: Fibrous nonwoven mats comprising polyetherimid fibers and a binder comprising a resin and an adhesion promoter, and method of making the mat are disclosed. These mats have several uses and are particularly suited as facer mats for fiber reinforced thermoplastic thermoformable materials. When used as a facer, the mat bonds to the thermoformable material and provides a resin rich outer layer and facilitates bonding to a decorative cover.
Abstract: The present invention relates in general to a variety of emulsion compositions, and more particularly, to emulsion compositions and methods for preparing these emulsion compositions which employ novel polymeric emulsifaction techniques. The emulsion compositions of this invention although applicable to a variety of applications provide particularly stable low viscosity polymeric emulsions useful for example in connection with wet wipes for the treatment of adult or baby dermatitis, make-up removal and other skin care applications. The stabilizing composition used in the emulsions according to the present invention comprise phenoxyethanol.

Abstract: A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a (hydroxyalkyl)urea and/or a .beta.-hydroxyalkyl amide crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The crosslinking agent is free of formaldehyde. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.
