A textile sizing agent wherein satisfactory fluff binding effect, a cohesion force and wear resistance which polyvinyl alcohol resin intrinsically has are not impaired, preparation of a sizing liquid is easily made, dividing properties at the time of sizing is good, sizing with very few troubles of thread breakage at the time of sizing is possible, and shedding properties of a sized yarn obtained at the time of weaving and a disadvantage of thread breakage can be greatly improved, thereby improving the weaving efficiency. The textile sizing agent is composed of polyvinyl alcohol resin (I), modified starch (II) and water-soluble cellulosic compound (III) as active ingredients, and their compounding ratios by weight satisfy the relation: (I)/((II) + (III)) 80/20, and is formed of an aqueous solution satisfying the following conditional expressions 1 - 3, 0.27X - 0.7 log10?Y 0.27X + 0.6 (expression 1), 20 Y 300 (expression 2), (A) / (B) 0.5 (expression 3), where X, Y, (A) and (B) are as defined in the specification. |
