摘要
针织物平幅连续前处理工艺具有高效、节水、低成本等优势,但处理后练漂半制品存在后续染色表观得色量较低的问题。为寻找解决这一问题的方法,对平幅前处理后棉针织物的性能及棉纤维的结构进行测试分析。研究结果表明:与传统浸渍前处理相比,采用平幅前处理后棉针织物的强力较高,白度及毛效相当,平幅轧染后的固色率及K/S值偏低;平幅前处理后棉纤维的超分子结构与传统浸渍前处理织物存在较大差异,平幅前处理后纤维结晶度较高,纤维内孔径分布范围较窄,孔道总容积及孔内表面积较小;通过联合半丝光处理优化棉针织物平幅前处理工艺,解决了棉针织物平幅前处理后染色效果不好的问题。
The open width continuous pretreatment of knitted fabric has the advantages of high efficiency,water saving and low cost.However,there is a problem of low apparent color yield in subsequent dyeing of semi-finished products after the treatment.In order to solve this problem,cotton knitted fabric properties and fiber structure after the open width pretreatment were measured and analyzed.The results show that compared with the traditional impregnation pretreatment,the cotton knitted fabric after open width pretreatment has higher strength,similar whiteness and capillary effect,lower fixation rate and K/S value after pad dyeing,the supramolecular structure of the cotton fiber is quite different from that of the traditional impregnation pretreatment.Compared with the impregnation process,the crystallinity of the fiber after open width pretreatment is higher,the pore size distribution is narrower,and the total pore volume and pore surface area is smaller.By adding semi-mercerizing treatment,the open width pretreatment process is improved.
