06 May 1991TL;DR: In this article, a method for making a heat resistant nonwoven fabric is provided, in which a formaldehyde-free binder composition containing a carboxy group, or carboxyl anhydride, or salts of a car boxy group is used.
Abstract: A method for making a heat resistant nonwoven fabric is provided. A formaldehyde-free binder composition containing a carboxy group, or a carboxylic anhydride, or salts of a carboxy group; and a β-hydroxyalkyl amide contacts a nonwoven fabric containing heat-resistant fibers, and heating the binder composition is effected.

TL;DR: In this paper, a process for the gel or surface postcrosslinking of water-absorbing polymers is described, in which the polymers are treated with a surface post-cross-linking solution and during or after the treatment are postcrosslinked and dried by means of an increase in temperature.
Abstract: The invention relates to a process for the gel or surface postcrosslinking of water-absorbing polymers in which the polymers are treated with a surface postcrosslinking solution and during or after the treatment are postcrosslinked and dried by means of an increase in temperature, the crosslinker being a compound of the formula in which R1 and R2 independently of one another are H, hydroxyl, phenyl or C1-C6-alkyl, R3 is hydrogen, C1-C12-alkyl, C1-C12-alkenyl or C6-C12-aryl and R4 and R5 independently of one another are C1 -C 12-alkyl, C1 -C 12-alkenyl, C6 -C 12-aryl, hydroxyl, C1 -C 12-alkoxy or hydrogen, dissolved in an inert solvent, to water-absorbing polymers which can be obtained by said process, and to their use in hygiene articles, packaging materials and nonwovens.

14 Oct 1994TL;DR: In this article, a method for strengthening a cellulosic substrate by treating the substrate with a formaldehyde-free curable aqueous composition and curing the composition was proposed.
Abstract: This invention relates to a method for strengthening a cellulosic substrate by treating the substrate with a formaldehyde-free curable aqueous composition and curing the composition. The cellulosic substrates include, for example, paper oil- and air-filter stock, rayon nonwoven wipes, cellulosic laminating stock, cotton woven fabrics, and wood flakes suitable to be consolidated into flakeboard.
