    Abstract: A method of preparing a laminate having increased peel strength and solvent resistance which involves (A) applying an adhesive composition to a surface of a first sheet; (B) exposing the adhesive composition on the surface of the first sheet to incoherent, pulsed ultraviolet radiation from a dielectric barrier discharge excimer lamp; (C) bringing a surface of a second sheet in contact with the adhesive composition-bearing surface of the first article; and (D) allowing the adhesive composition to cure. The incoherent, pulsed ultraviolet radiation has a single narrow wavelength band within the range of from about 260 to about 360 nanometers. The adhesive composition includes from about 94 to about 60 percent by weight of a cycloaliphatic diepoxide, from about 1 to about 10 percent by weight of a cationic photoinitiator, and from about 5 to about 30 percent by weight of a vinyl chloride-vinyl acetate-vinyl alcohol terpolymer, all based on the weight of adhesive composition. The sheets desirably are films and nonwoven webs composed of cellulosic fibers, polyolefin fibers, or a mixture of cellulosic fibers and polyolefin fibers. The method is particularly well suited for the preparation of such laminates as industrial wipers, workwear, medical fabrics, and the like.

    Abstract: A process (1, 101, 201) for separating a fibrous target component (21) from textile waste (2, 5) is shown, said textile waste (2, 5) containing the target component (21) and at least one ancillary component (22), whereby the target component (21) consists of water-swellable textile fibers (51) with a density higher than the density of water, the process (1, 101, 201) comprising the steps: a) dispersing the comminuted textile waste (5) in an aqueous solution (7) to obtain a suspension (8) containing the textile waste (5), and b) separating the dispersed textile waste (5) into a high-density target fraction (81) comprising the target component (21), and a low-density residual fraction (82) comprising the at least one ancillary component (22), according to the respective density of said components (21, 22). In order to provide a reliable, fast process for the separation of water-swellable fibers from other textile fibers which are similar in density, it is proposed, that the aqueous solution (7) is an alkaline aqueous solution (7) and the target component fibers (51) are swelled in the alkaline aqueous solution (7) prior to step b), thereby increasing the density and weight of said target component (21) relative to the density and weight of the ancillary component (22).

    Abstract: In a method for controlling shrinkage of a composite, a dried hydrophobically modified cellulose-based fiber is exposed to a slow acting resin system having a first curing time. An excess amount of the slow acting resin system is removed to separate out the pre-wetted hydrophobically modified cellulose-based fiber. The pre-wetted hydrophobically modified cellulose-based fiber is mixed with a fast acting resin system to form a mixture. The fast acting resin system has a second curing time that is less than the first curing time. The mixture is molded at a predetermined temperature. The fast acting resin system is cured prior to the slow acting resin system, and the slow acting resin system flows into free space within the curing fast acting resin system prior to the slow acting resin system being cured.
