空气喷射变形丝的芯吸效应

摘要

利用毛细管上升法和液滴吸收法研究了聚酯、黏胶、聚酰胺、聚酯／黏胶和聚酯／聚酰胺空气喷射变形丝的芯吸率和吸湿率。结果表明，空气变形后复丝的芯吸率提高。与聚酰胺和黏胶空气喷射变形丝相比，聚酯空气喷射变形丝显示出较大的芯吸率。黏胶空气喷射变形丝显示出最低的芯吸率。与同样的未变形丝相比，混合的空气喷射变形丝显示出较大的芯吸率。%Wicking and moisture absorbency rates of polyester, viscose, polyamide, polyester/viscose and polyester/ polyamide air-jet textured yarns were studied by using capillary rise and drop absorbency methods. The results revealed that the wicking rate of filament yarns increases after air-texturing. The polyester air-textured yarn shows more wicking rate than polyamide and viscose air-textured yams. The viscose air-textured yarn shows the lowest wicking rate. The blended air-texture yarns show more wicking rate than their parallel untextured yams.
