A formulation for finishing a cellulosic substrate, or a blend thereof, in a finish bath, the formulation comprising from about 3.0% to about 60.0% by weight of non-formaldehyde dimethylurea/glyoxal (DMUG), or an analog thereof, and from about 0.1% to about 4.0% by weight of one or more additives selected from dicyandiamide, choline chloride, ethyleneurea, propyleneurea, urea, dimethylurea, and combinations thereof, wherein the percent by weight is given in terms of percent weight of the finish bath, and wherein the formulation is substantially free of dimethyloldihydroxyethyleneurea (DMDHEU), and methods of use thereof.

The invention relates to porous polymeric cellulose prepared via cellulose crosslinking. The porous polymeric cellulose can be incorporated into membranes and/or hydrogels. In preferred embodiments, the membranes and/or hydrogels can provide high dynamic binding capacity at high flow rates. Membranes and/or hydrogels comprising the porous polymeric cellulose are particularly suitable for filtration, separation, and/or functionalization media.

Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention have many uses, such as, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.

An aqueous finishing composition includes at least one polyglycerol, at least one organic polycarboxylic acid containing at least three carboxyl groups, at least one esterification catalyst, at least one plasticizer, and at least one thickener selected from a group consisting of cellulose derivatives, succinoglycans and xanthans.

Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a fiber having a surface region and an interior region, includes a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety chemically modified with a modification agent. The fiber has a transverse cross-section including the interior region comprising the polymer having a first degree of modification and the surface region comprising the polymer having a second degree of modification greater than the first degree of modification.

A method for fabricating a bandage comprises the following steps: preparing multiple complex yarns each comprising chitosan fibers and rayon fibers; (b) weaving solely the multiple complex yarns to form a preformed bandage; (c) immersing the preformed bandage in an acid alcohol, and then washing the preformed bandage by alcohol to obtain an alcohol-washed bandage; and, (d) heating the alcohol-washed bandage to obtain the bandage. The bandage related to the method is comprised of complex yarns, wherein each of the complex yarns is composed of chitosan fibers and rayon fibers. By means of immersing the preformed bandage into an acid alcohol, the bandage thus obtained has enhanced tensile strength, decreased dissolution rate and reduced hemolytic dose.

The present invention addresses the problem of improving friction characteristics, when wet, of fibers to which a treatment agent for short fibers is adhered, and improving the heat resistance of the treatment agent for short fibers. This treatment agent for short fibers does not substantially include a phosphate compound, but does contain the fatty acid (A) below and a non-ionic surfactant. The fatty acid (A) is at least one fatty acid selected from C1-6 fatty acids, C1-6 hydroxy fatty acids, and salts of the aforementioned fatty acids.
