  • Patent number: 5698688
    Abstract: Modified cellulosic fibers are formed by (1) esterifying cellulosic fibers with a 1,2-disubstituted alkene that has at least one carboxylic acid group reactive with cellulosic hydroxyl groups and (2) oxidizing the esterified fibers to form aldehyde groups. The modified fibers are useful in paper products, which tend to have temporary wet strength. Strength additives may be included in the paper product to impart a higher level of temporary wet strength or permanent wet strength.

  • Patent number: 5690790
    Abstract: The present invention relates to paper products having temporary wet strength. The paper products contain cellulosic fibers that are treated with a polyaldehyde polymer having free aldehyde groups and a water soluble polyhydroxy polymer. The initial wet strength obtained with the combined use of these materials is significantly greater than that obtained by use of either the polyaldehyde or pelyhydroxy polymer alone. At the same time, the wet strength decays at a rate that is rapid enough to enable the paper product to be flushed under conditions of normal use.

C., and monomer units that form a homopolymer having a T.sub.g of less than 25.degree. C. The hydrocarbon solvent consists essentially of one or more branched chain hydrocarbons containing from 10 to 16 carbon atoms. The invention relates to hair styling and conditioning products such as rinses, leave on conditioners, and combination shampoo products useful for cleansing, styling and conditioning the hair.

  • Patent number: 5656746
    Abstract: A temporary wet strength polymer and compositions for paper products, e.g., toilet tissue, is disclosed. The temporary wet strength polymer is the oxidation product of an esterified polyhydroxy polymer, more preferably of an esterified polysaccharide. The esterified polymer compound is formed by reacting the polyhydroxy polymer with a 1,2-disubstituted alkene compound that has at least one carboxylic acid group. The temporary wet strength polymer provides paper products having an initial wet strength that enables use of the product in the moistened condition, along with a suitable wet strength decay rate.

  • Patent number: 5626571
    Abstract: A nonwoven that is exceptionally soft yet sufficiently strong for use in absorbent articles is disclosed. The soft, strong nonwoven includes fibers comprising polyethylene, at least a portion of which are consolidated. The soft, strong nonwoven has a cross-machine direction tensile strength of at least about 300 g/in and a cross-machine direction elongation at break of at least about 40%.The soft, strong nonwoven is preferably formed by permanently stretching an inelastic base nonwoven in the cross-machine direction. The preferred base nonwoven has certain properties which allow it to have sufficient strength after stretching, while being exceptionally soft, such that the resultant permanently stretched, soft, strong nonwoven is particularly suitable for use as a topsheet or a back sheet component in disposable absorbent articles.
