| Abstract: | In order to obtain polyester fibers with a pore structure, the polyester fibers with a hollow structure are immersed in NaOH solution by alkali treatment, and the surface of the hollow polyester fiber is etched by the hydrolysis of NaOH on the polyester, thereby forming a porous fiber structure. The morphological characteristics, porosity, mechanical properties and hydrophilicity of the fabric prepared under different mass concentration, temperature, and immersion time conditions were investigated. The results show that the alkali treatment method can effectively prepare porous polyester fibers with a multi-scale distribution of micro-level(150 μm) and sub-micro-level(150 nm). The optimal preparation process parameters are NaOH solution concentration is 200 g/L, the temperature is 70 ℃ and the immersion time is 1.5 h. |
