Abstract:

In order to simplify the synthesis process of linear polyether-blocked amino silicone oil, the linear polyether-blocked amino silicone oil (LEPS) was prepared by ring opening polymerization using diterminal aminoether and diterminal epoxy polyether silicone as monomers and isopropyl alcohol as a solvent, and the LEPS was applied to the soft finishing of knitted cashmere fabric. The physicochemical properties of LEPS and fabrics finished with LEPS were characterized by means of Fourier transform infrared spectrometer, thermogravimetric analysis, multi-functional surface analysis electron spectrometer and scanning electron microscopy. The results show that when the mole ratio of two monomers is 1:1, the ammonia value of LEPS is 0.14 mmol/g, and the molar mass is 7.39×10 4 g/mol, and the emulsion has excellent stability. The fabric finished with LEPS has outstanding soft and fluffy properties, hand feeling to grade 5 and good hydrophilicity, moisture permeability and static resistance as well as low degree of yellowing. LEPS has the advantages of excellent comprehensive properties and simple preparation process.

Key words: diterminal amino polyther, diterminal epoxy polyether silicone, linear polyether-blocked amino silicone, knitted cashmere fabric, soft finishing of fabric
