摘　　要：在聚合工艺的酯化-缩聚阶段添加超细硅藻土等助剂制备舒适性聚酯熔体,在前述共聚酯中添加了一定比例的水溶性聚酯,使用具有异形喷丝孔的纺丝组件,纺制具有十字形截面的聚酯纤维。用热稀碱溶液将前述纤维中的水溶性聚酯挖蚀溶解,在纤维表面至内部形成高空隙蜂窝状态,这些蜂窝状空隙使纤维密度大幅度下降的同时透气透湿性能也明显增加。研究结果表明,该工艺制造的高空隙聚酯纤维透气导湿性能优良,纤维形成的织物舒适、蓬松、轻盈。In the esterification condensation stage of the polymerization process,additives such as ultrafine diatomaceous earth are added to prepare a comfortable polyester melt.A certain proportion of water-soluble polyester is added to the aforementioned copolyesters,and a spinning component with irregular spray holes is used to spin polyester fibers with a cross shaped cross-section.Using a hot dilute alkaline solution,the water-soluble polyester in the aforementioned fibers is etched and dissolved,forming a high-altitude honeycomb state from the surface to the interior of the fibers.These honeycomb like voids significantly reduce the density of the fibers,while also significantly increasing their breathability and moisture permeability.The research results indicate that the high-altitude gap polyester fibers manufactured by this process have excellent breathability and moisture conductivity,and the fabrics formed by the fibers are comfortable,fluffy,and lightweight.
