将丙烯酸十二氟庚酯(FA),丙烯酸羟丙酯(HpAA)为单体,偶氮二异丁腈(AIBN)为引发剂在聚氨酯预聚体中进行聚丙烯酸酯自由基聚合,然后用丁酮肟(EtAO)进行完全封端,制得新型易去污整理剂聚氨酯改性氟代聚丙烯酸酯(FPUA).FPUA附着在纤维表面时纤维与空气的界面上富集着疏水的含氟链段,能使整理后棉织物与水的接触角达到146.5°,与油的接触角达到132°;当FPUA用量为1.5 g/100 mL H_2O,使用100℃烘5 min后180℃高温焙烘2 min的工艺时,疏水性达到95分,疏油等级6级,易去污可达到5级.

A novel soil release finishing agent polyurethane modified fluorinated acrylate(FPUA) is prepared with the copolymerization of hydroxypropyl acrylate (HpAA) and dodecafluroheptyl acrylate (FA) in the medium of polyurethane solution by the initiation of azobisisobutyronitrile (AIBN) with butanone oxime (EtAO) used as a blocking agent.The fluorine groups enriching at the fiber-air interface cause the contact angle of water and salad oil on the cotton fabrics to increase to 146.5° and 132°.And when the dosage of FPUA is 1.5 g/100 mL and the finishing process is at 100℃ baking for 5 minutes and then at 180℃ for another 2 minutes,the hydrophobicity can reach 95,with the oil-repellent grade and the soil-release grade reaching grade 6 and 5,respectively.
