Abstract:

Modified silica particles (V-SiO2) and stearyl acrylate (SA) were grafted onto cotton-fabric via electron-beam (EB) irradiation to achieve hydrophobicity. The effects of absorbed dose, V-SiO2 particle size, mass fraction of the V-SiO2 particles, the mass ratio of particle modifier vinyltrimethoxysilane (VTMS) to tetraethyl orthosilicate (TEOS), and mass fraction of SA on the hydrophobicity of the modified cotton-fabric were investigated. The change in the hydrophobic property was characterized by measuring the water contact angle, spray testing grade, anti-hydrostatic pressure, and water vapor permeability. The results showed that the modified cotton-fabric could attain a water contact angle of 152° from 143°, spray testing grade of 4 from 1, anti-hydrostatic pressure of 264 mm from 130 mm, and water vapor permeability of 10.247 3 g/(m2·h) from 12.367 5 g/(m2·h). Furthermore, the optimized reaction conditions were as followers:V-SiO2 particle size, 240 nm; mass ratio of VTMS to TEOS, 6:1; V-SiO2 mass fraction, 5%; SA mass fraction, 30%; and absorbed dose of EB, 43 kGy.
