ABSTRACT:
An aqueous sizing composition for treating glass fibers, the treated glass fiber strands and bulked yarn prepared from the treated glass fiber strands are provided to give treated glass fiber strands having an improved processability and characteristics in yarn bulking operations. The aqueous sizing composition has a modified starch that has Brabender values of gel temperature in the range of about 65.degree. C. to about 90.degree. C. with values maximum viscosity in the range of about 500 B.U. to about 1200 B.U. for a 9.5 dry percent concentration or equivalent. The aqueous sizing composition also has nonionic lubricants, wax, emulsifiers, starch plasticizer, and ester-modified amino silane coupling agent and possibly a biocide and or fungicide and cationic lubricant for treating glass fibers. The aqueous sizing composition can also be used to treat glass fibers of fine diameter, where the aqueous sizing composition has the aforedescribed ingredients including a poly (ethylene oxide) friction reducing agent, cationic amphoteric or nonionic wetting agent, and a fluorochemical surfactant.
