Paper sizing compositions comprising (a) cellulose-reactive size, (b) dispersant system comprising primary anionic dispersant, and secondary dispersant selected from cationic and/or non-ionic dispersant, and (c) inorganic salt.

Paper sizing composition

Aqueous paper size dispersions comprising: a) at least one paper sizing compound, and b) a water-soluble dispersant containing at least two hydrophilic groups and at least one hydrophobic group. Processes for sizing paper utilizing the aqueous paper size dispersions, and paper made by the processes.

Paper size dispersions

An aqueous, coatable, thermally condensable composition is disclosed. The coating is based on dispersions of vinyl acetate polymers in water. Uniquely, the coating can be advantageously used for both nylon and polyester yarns. The coated yarns exhibit performance equivalent to or better than coated yarns based on traditional compositions.

Method of coating nylon and polyester fibers with water dispersible polyvinyl acetate and coating achieved therefrom

Improved dyeing processes for yarn and fabric materials are described. Dye pattern definition on a textile material is enhanced by treating the fabric or the fibers from which it is made with a quaternary ammonium compound and by including in the dye composition a gum which will react with the quaternary ammonium compound to form a viscous gel. The gel minimizes migration of the dye prior to fixation of the dye, and therefore pattern definition is improved. Similar improvements can be obtained when space dyeing yarn that comprises fibers that have been so treated.
