　　摘 要：对长氟碳链聚合物带来的环境污染问题，利用细乳液聚合合成了六碳短链含氟丙烯酸酯乳液，并在聚合物体系中引入改性后的SiO 2来改善织物的整理效果。利用FTIR和DLS表征了聚合物乳液的结构和粒径分布，考察了不同条件下水、油接触角的变化趋势，表征了整理前后棉织物的结构组成、表面元素以及形貌变化，研究了棉织物的拒污性、耐水洗牢度以及物理力学性能在整理前后的变化。结果表明：当使用的氟单体质量分数为50%、烘焙温度为150℃、烘焙时间为150 s时，整理后织物表面的水接触角为147.9°、油接触角为141.2°，拒油等级能够达到3级，且整理后的棉织物具有一定的防污性，对多种液体具有良好的拒液性;织物在经过20次水洗后仍能保持较好的拒水拒油效果;织物的物理力学性能在整理前后变化不大，几乎不影响其服用性能。

　　Abstract： In view of environmental pollution caused by long fluorocarbon chain polymers， we prepared a six-carbon short-chain fluorinated acrylate emulsion by miniemulsion polymerization and introduced modified SiO 2 nanoparticles into the polymer system to promote the finishing effect of fabrics. The structure and particle size distribution of polymer emulsion were characterized by means of FTIR and DLS. The variation trend of water and oil contact angles under different conditions were investigated， and the changes in structural composition， surface elements and morphology of untreated and treated fabrics were characterized. The anti-fouling properties， water resistance， physical and mechanical properties of the cotton fabrics before and after finishing were discussed. The results indicated that when the mass fraction of fluorinated monomer used was 50%， the baking temperature was 150℃， the baking time was 150 s， the water contact angle on the surface of finished fabric was 147.9° and the oil contact angle was 141.2° and the oil repellency can reach level 3. In addition， the finished cotton fabric had certain anti-fouling property and good liquid repellency for a variety of liquids. The fabric can maintain good water and oil repellency even after 20 times of washing. The physical and mechanical properties of the treated fabric changed little before and after finishing， and the wearability was almost unaffected.
