亲水拒油含氟整理剂的合成及其在棉织物上的应用

Synthesis of fluoro-containing hydrophilic and oleophobic finishing reagent and its application on the cotton fabric

以F113和全氟聚醚酰氟为原料,合成了全氟聚醚二酰基过氧化物,并用来引发二甲基二烯丙基氯化铵聚合,得到含有全氟烷氧基(末端基团)的二甲基二烯丙基氯化铵聚合物Pf,通过传统的轧-烘-焙过程将其整理到棉织物上.通过测试水和正十二烷在整理后织物上的接触角对该聚合物的亲水拒油性能进行评价.结果表明:聚合物Pf具有良好的亲水拒油性,对水的接触角为0°,对正十二烷的接触角为116.3°,同时整理后的棉织物具有很好的亲水拒油耐洗性.

Perfluoropolyether diacyl peroxide was prepared using Fl13 and perfluoropolyether fluoride as raw materials. Then it was used to initiate the polymerization of dimethyldiallyl ammonium chloride to obtain the perfluoroalkoxyl end-capped polymer Pf. Pf was applied on the cotton fabric by pad-dry-cure process. The water and hexadecane contact angles of finished fabrics were measured to evaluate the hydrophilic and oleophobic properties of the polymer. The results showed that Pf had good hydrophilicity and oleophobicity, the contact angle to water and dodecane was 0° and 116.3°, respectively. And the hydrophilicity and oleophobicity of finished cotton fabric had good washing fastness.
