摘　　要：以异氟尔酮二异氰酸酯(IPDI)、聚丙二醇(PPG)、三羟甲基丙烷(TMP)、N-甲基二乙醇胺(MDEA)为原料,合成了聚氨酯预聚体;再与双端氨丙基硅油反应,经中和、乳化制备了一种用于棉织物的聚氨酯改性有机硅风格整理剂。通过单因素试验优化了合成工艺条件:R值[n(NCO)/n(OH)]为2.2,MDEA和TMP用量分别为9%和1%(对单体总质量)。在整理剂用量80 g/L、浴比1∶30、150℃焙烘90 s的工艺条件下,经整理的棉织物经向动摩擦系数MIU由0.279降至0.199,经向弯曲刚度B由0.104 2 gf·cm2/cm降至0.090 6 gf·cm2/cm,急弹、缓弹折皱回复角分别由186°、208°增至219°、231°,织物具有良好的滑弹手感。Polyurethane prepolymer was prepared with isophorone diisocyanate （IPDI）, poly propylene glycol （PPG）, trimethylolpropane （TMP）, N-methyldiethanolamine （MDEA） as the raw materials; then the preploymet was reacted with the double-ended aminopropyl silicone, and a kind of polyurethane-modified silicone style finishing agent was synthesized after neutralization and emulsification. The synthetic process was optimized by single factor experiment as follows： R value （molar ratio of NCO to OH） was 2.2, the weight of MDEA and TMP were 9% and 1% （on the total mass of the monomer）, respectively. Compared with the un- treated cotton fabric, the MIU of the treated fabric was decreased from 0.279 to 0.199, the bending rigidity （B） of the treated fabric was decreased from 0.104 2 gf.cm2/cm to 0.090 6 gf.cm2/cm, the urgent elastic recovery angle of treated fabric was increased from 186° to 219°, the gentle elastic recovery angle of treated fabric was raised from 208° to 231°, and the treated fabrics had good slip elastic handle, when the dosage of finish- ing agent was 80 g/L, bath ratio was 1：30, and curing temperature and time were 150 ℃ and 90 s, respectively.
