Synthesis and application of polyurethane-modified silicone style finishing agent
摘要
Abstract
Polyurethane prepolymer was prepared with isophorone di socyanate (IPDI), poly propylene gly⁃col (PPG), trimethylolpropane (TMP), N- methyldiethanolamine (MDEA) as the raw materials; then the preploy⁃mer 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 opti⁃mized by single factor experiment as fol ows: 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.关键词
