Animal glues have been used for many years as a warp size to protect yarn from breaking and chafing during weaving. These glues have particular applications on rayon, acetate, and viscose, and cotton, nylon, Orlon, and Dynel have also been sized successfully. Sizing solutions commonly contain 2.5 to 8% glue solids using various grades of glue, depending on the operation. The glue is usually modified with plasticizers and softening agents such as sulfonated oils, glycerin, and wax emulsions as well as wetting agents. The modifiers are generally used at a level of 20 to 45% of the glue solids. These agents act to lubricate and provide flexibility to the size film on the yarn.
In the process of weaving crepe fabrics, the yarn is held in a tight twist by a glue film during weaving. The fabric is washed after weaving to remove the glue, which releases the twist and forms the characteristic crepe effect. Animal glues are also used in textile finishing as dye leveling agents, and in silk screen printing.
