纳米ZnO在棉纤维表面的生长及织物拒水整理研究

Growth of nano-ZnO on cotton fabrics and study on the water repellent finish

用水热生长法在棉纤维表面生长纳米ZnO,再用十二烷基三甲氧基硅烷对织物表面进行低表面能处理,提高其疏水性能.用扫描电子显微镜对纤维表面形貌进行观察,并用X-射线衍射仪对棉纤维表面生长的ZnO晶体结构进行测试分析,还对织物的疏水性能进行了测试,探讨了影响织物表面疏水性能的因素.研究表明:ZnO可在棉纤维表面生长并形成微观粗糙的纳米结构,织物经过简单的疏水化处理即可使其拒水性能达到100分.

Growth of nano-ZnO on cotton fiber was conducted via a hydrothermal method,and a subsequent low surface energy treatment on the fabric with n-dodecyltrimethoxysilane was carried out to improve the hydrophobicity of fabric.The surface configuration of fiber was characterized by scanning electron microscopy and the crystal structure of ZnO grew on the cotton fiber surface was analyzed by X-ray diffractometer.Hydrophobic property of the treated fabrics was evaluated.Factors influencing the hydrophobic property of the fabric surface were discussed.The results showed that ZnO could grow on the surface of cotton fibers and form microscopic rough nano structure.The hydrophobicity of the fabrics could easily reach level 100 with a simple hydrophobic treatment.
