  • Publication number: 20110308022
    Abstract: A process for imparting flame resistance and the flame resistant fabrics produced by such process are provided. The process for imparting flame resistant properties involves treating a target fabric with one or more flame retardant chemicals (and, preferably, a softening agent) and then curing the treated fabric to durably affix the flame retardant to the fabric. In many cases, it may be desirable to subject the treated fabric to mechanical face finishing to increase softness. Optionally, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals, eliminating the need for one or more additional manufacturing processes. Alternately, soil repellent agents may be applied to only one side of the treated fabric after the application of the flame retardant chemicals. The present fabrics exhibit improved performance and tear strength, even after repeated launderings, as compared to conventionally treated fabrics.

  • Patent number: 6361651
    Abstract: The wet strength softness absorbency, absorbency rate and other valuable properties in paper products, tissues, wipes, towels, etc. can be improved by using, in the paper forming process, a cellulosic material comprising a carboxymethyl cellulose material associated with a monomeric or polymeric cationic additive material. A process of the invention comprises a fiber surface carboxymethylation and an aqueous medium followed by blending the modified fibers with a cationic additive under varying conditions and wet forming the tissue and towel products. The additive is typically a cationic additive that preferentially associates with a carboxymethyl group on the cellulose surface. The affinity between the positively charged cationic groups in the polymeric or monomeric additive material to the negatively charged carboxyl group in the carboxymethyl cellulose modified fiber improves various attributes of the paper products.
