  • Publication number: 20020005262
    Abstract: Paper comprising aldehyde modified cellulose pulp having selected aldehyde content. Another embodiment involves a method of preparing celullose aldehydes using selective oxidation with a limited amount of oxidant and a nitroxyl radical mediator and defined reaction conditions to provide oxidized cellulose material with effective aldehyde content making it particularly suitable for use in making paper with desirable wet strength, temporary wet strength and dry strength properties.

  • Publication number: 20010025102
    Abstract: Stable, cold water soluble, ready for use starch aldehyde compositions and the method of preparation of such compositions wherein an aqueous dispersion of a fluidity or converted starch acetal is hydrolyzed under acidic conditions to form the starch aldehyde which is then spray dried into a cold water soluble starch aldehyde powder.

  • Patent number: 5951715
    Abstract: A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a polysaccharide aldehyde and/or acetal at a pH of 1 to 8 to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the polysaccharide aldehyde and/or acetal with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. 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.
