Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous sizing agent which eliminates the need of a heat cleaning step and a surface treatment step in cases using an aqueous sizing agent containing starch, suppresses increase of the generation rate of static electricity in cases using an aqueous sizing agent containing an epoxy resin and variation of yarn quality in a high-temperature environment and is stable and excellent in weavability.SOLUTION: An aqueous sizing agent comprises 100 pts. mass of a silane coupling agent (A), 50-700 pts. mass of a film-forming agent (B), 10-50 pts. mass of an antistatic agent (C) and 10-50 pts. mass of a flexibilizer (D) and is free of starch and an epoxy resin. 【課題】澱粉を含む水系サイズ剤を用いた場合のヒートクリーニング工程および表面処理工程が不要であり、エポキシ樹脂を含む水系サイズ剤を用いた場合の静電気の発生量の増大および高温環境下での糸質の変動が抑制され、安定かつ優れた製織性を実現可能な水系サイズ剤を提供する。【解決手段】本発明の水系サイズ剤は、シランカップリング剤（Ａ）の１００質量部と、皮膜形成剤（Ｂ）の５０〜７００質量部と、帯電防止剤（Ｃ）の１０〜５０質量部と、柔軟剤（Ｄ）の１０〜５０質量部とを含有し、澱粉およびエポキシ樹脂を含有しない。【選択図】なし
