摘要
为了改善棉纤维易污染和易起皱问题,采用NaOH/尿素体系构筑稳健的微纳结构纤维表面,十六烷基三甲氧基硅烷(HDTMS)降低纤维表面能,丁烷四羧酸(BTCA)提高纤维耐久性和抗皱性能。利用傅里叶红外光谱、扫描电子显微镜、X射线光电子能谱和静态接触角测量仪等技术对改性后的棉织物进行表征,并对其功能性进行评价。结果显示:NaOH质量分数10%、HDTMS质量分数4%、BTCA质量分数4%时,处理后的棉织物显示出良好的超疏水性、抗皱性、防污性和自清洁性;且分别经受30次洗涤和3500次摩擦后,水接触角依然超过150°,显示了良好的超疏水耐久性。
To solve the problem of cotton fibers easy contamination and wrinkling,stable fiber surface with micro/nano structure was constructed by NaOH/urea system.Hexadecyl trimethoxysilane(HDTMS)was used to reduce the surface energy of fibers.Butane tetracarboxylic acid(BTCA)was adopted to improve fiber durability and anti-wrinkle.The modified cotton fabric was characterized by fourier transform infrared spectroscopy,scanning electron microscopy,X-ray photoelectron spectroscopy and static contact angle meter and so on.And functional properties were evaluated.Results showed that the treated cotton fabric had better superhydrophobicity,anti-wrinkle and self-cleaning property when mass fraction of NaOH was 10%,mass fraction of HDTMS was 4%and mass fraction of BTCA was 4%.And after 30 times washing and 3500 frictions,the water contact angle of modified fabric was still larger than 150°.It showed better superhydrophobic durability.
