PURPOSE: To provide a diorganopolysiloxane/acrylic ester copolymer emulsion composition capable of forming a soft film having high flame retardancy and causing no cracking even at extremely low temperatures, by hardening at room temperature by removal of water, and to provide a highly flame-retardant fabric treated with the above emulsion composition. CONSTITUTION: This emulsion composition for treating fabrics is characterized by comprising (A) an emulsion of a copolymer made from (a-1) a diorganopolysiloxane having at least two silison atom-bound alkenyl groups in the molecule with the molecular chain ends blocked with hydroxyl groups and (a-2) an acrylic ester-based monomer, (B) colloidal silica, (C) a condensation reaction promotive catalyst, and (D) an inorganic flame retardant. The other objective fabric treated with the above emulsion composition is provided. 직물 처리용 에멀젼 조성물을 함유하는 디오가노폴리실록산/아크릴레이트 에스테르 공중합체는 매우 낮은 온도에서도 균열되지 않으며 가요성이고 상당히 난연성인 피복물을 형성하면서, 물의 제거를 통해 실온에서 경화된다. 상당히 난연성인 직물은 에멀젼 조성물로 처리하여 제공될 수 있다. 당해 에멀젼 조성물은 분자 1개당 규소 결합된 알케닐 그룹을 두 개 이상 갖는 하이드록실 말단 차단된 디오가노폴리실록산(a-1)과 아크릴레이트 에스테르 단량체(a-2)와의 공중합체의 에멀젼(A), 콜로이드성 실리카(B), 축합 촉매(C) 및 무기 난연제(D)를 함유한다.
