摘要

利用电子束辐射技术，将改性二氧化硅（V-SiO,2,）和丙烯酸十八酯（SA）共同接枝到织物表面，赋予织物疏水性能。探讨了吸收剂量、V-SiO,2,球粒径、V-SiO,2,质量分数、改性剂乙烯基三甲氧基硅烷（VTMS）相对于正硅酸四乙酯（TEOS）的质量比（,m,VTMS,：,m,TEOS,）和SA单体质量分数对织物疏水效果的影响。通过测量织物对水的接触角、淋洗等级、耐水压值、透湿率等参数来表征织物疏水性能的变化。结果表明，电子束辐照改性后棉织物静态水接触角由143°提高到152°，淋洗等级由1增加到4级，耐水压值由130 mm变为264 mm，透湿率由12.367 5降为10.247 3 g/（m,2,·h）。优化的反应条件为V-SiO,2,球粒径240 nm，,m,VTMS,：,m,TEOS,=6：1，V-SiO,2,球质量分数5%，SA单体质量分数30%，吸收剂量43 kGy。

Abstract

Modified silica particles (V-SiO,2,) and stearyl acrylate (SA) were grafted onto cotton-fabric via electron-beam (EB) irradiation to achieve hydrophobicity. The effects of absorbed dose, V-SiO,2, particle size, mass fraction of the V-SiO,2, 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/(m,2,·h) from 12.367 5 g/(m,2,·h). Furthermore, the optimized reaction conditions were as followers:V-SiO,2, particle size, 240 nm; mass ratio of VTMS to TEOS, 6:1; V-SiO,2, mass fraction, 5%; SA mass fraction, 30%; and absorbed dose of EB, 43 kGy.
