Abstract:
Certain antimicrobial agents, particularly chitosan- or chitin-based polymers, exhibit increased antimicrobial activity when coat ed onto the surface of a hydrophobic material such as polypropylene. When applied to the surface of a polypropylene nonwoven fabric, for example, the resulting material can be used for diaper liners to reduce odors and promote skin wellness.
Abstract:
A process for manufacturing a cellulosic paper product is provided. The process comprises forming an aqueous suspension of papermaking fibers; introducing a borate compound, preferably boric acid, into the aqueoussuspension; depositing the aqueous suspension onto a sheet-forming fabric to form a wet web; and dewatering and drying the wet web. The process of the present invention provides cellulosic paper products exhibiting a reduced malodor upon re-wetting.
Abstract:
The present invention is directed to ion-sensitive, water-dispersible polymers. The present invention is also directed to a method of making ion-sensitive, water-dispersible polymers and their applicability as binder compositions. The present invention is further directed to fiber-containing fabrics and webs comprising ion-sensitive, water-dispersible binder compositions and their applicability in water-dispersible personal care products.
Abstract:
A process for the production of a fiber having a permanently modified fiber morphology comprising a curl index of at least 0.2 resulting in a fiber with increased bulk, increased surface area and low density, the process comprising: (a) subjecting the fiber to treatment with steam at super atmospheric temperature and pressure for a sufficient period of time to render the fiber morphology permanent; and (b) explosively releasing the super atmospheric steam pressure.

Abstract:
Disclosed is a method for producing a water-swellable, water-insoluble chitosan salt having improved absorption properties. The method involves forming a mixture of a chitosan, water, an acid, and, optionally, a crosslinking agent, recovering the formed chitosan salt from the mixture and, optionally, treating said recovered chitosan salt with heat or under humid conditions.
