Plasma technology is emerging as a novel and environmentally friendly technology for surface modification of textile materials. It is possible to deposit very thin film with specific functional properties on the surface of textiles. The current study describes a novel approach for surface modification of 100% polyester textiles with plasma enhanced chemical vapor deposition （PECVD）. The chemical and structural nature of plasma polymers deposited at the surface of the samples with respect to discharge power was studied with FTIR spectroscopy. The functional property i. e. water repellency imparted was determined with spray test and contact angle measurement.%对于纺织材料的表面改性来说，等离子体技术正成为一种新兴且环境友好的技术。等离子体技术在纺织品表面可沉积具有特殊功能的薄膜。阐述了一种常压等离子体增强化学气相沉积法表面改性100％聚酯织物的新型方法。通过傅里叶变换红外光谱研究了沉积于样品表面上相对于放电功率的等离子体聚合物化学和结构性质。采用雾化试验和接触角测量赋予织物诸如疏水等的功能特性。
