雾聚合法制备耐磨棉织物

We report here a simple method to fabricate abrasive-resistant cotton fabrics via a mist polymerization of two monomers, polyurethane (PU) prepolymer and ethylene glycol (EG). The abrasion resistance of the fabric treated by this method has been increased by about one time according to Martindale test. The morphology and nanoscale hierarchical structures in the polymeric layer on the cotton surface were investigated by field emission scanning electron microscope (FE-SEM) analysis. The results confirmed the formation of thin polyurethane layer on the cotton surface which can increase the abrasion resistance. More experimental data suggest that the intrinsic properties of cotton fabric, such as water absorptivity, vapor transmissibility, mechanical properties, and flexibility, were inherited after the surface modification. These properties are of great significance in textile and medical applications.
