COLLECTING AGENT FOR GLASS FIBER YARN AND GLASS FIBER YARN USING THE SAME

摘要

A collecting agent for use in a glass fiber yarn being prepared by twisting strands each formed by collecting 200 to 800 glass filaments having an average diameter of 5 to 11 μm and being used as a wrap of the glass cloth, characterized in that it comprises a starch, a vegetable oil, a paraffin and an emulsifier, wherein the starch is an etherificated starch having an MS value of 0.001 to 0.025, and the vegetable oil has a saturation degree of 90 % or more. A glass fiber yarn produced by using the collecting agent is used as a warp, and is free from the formation of fluffs in a warping process and excellent in the stability of the tension applied to wraps during warping.
