阻燃粘胶/阻燃腈纶/棉混纺纱纺纱工艺与性能研究

Spinning technology of flame-retardant viscose/flame-retardant acrylic/cotton fiber blending yarns and their properties

选用阻燃粘胶纤维、阻燃腈纶、棉纤维3种原料,设计了混纺纱纺纱工艺,纺制出3种不同混纺比的阻燃混纺纱和纯阻燃粘胶、纯阻燃腈纶纱线。测试分析了纱线的阻燃性能、强伸性能和耐磨性能。结果表明:随着阻燃腈纶含量的减少,混纺纱的阻燃性能和耐磨性能逐渐变差,断裂强度和断裂伸长率相差不大,断裂强度介于纯阻燃粘胶纱线和纯阻燃腈纶纱线之间。

Flame-retardant viscose fiber/flame-retardant acrylic fiber/cotton fiber are selected to spin three blending yarns, pure flame-retardant viscose yarn and pure flame-retardant acrylic yarn through designed blended yarns spinning process. The flame-retardant,strength elongation and wear-resisting properties of yarns are tested and analyzed. The results show that the flame-retardant and wear-resistingproperties of blending yarns are worse with the decrease of the content of flame retardant acrylic fiber, the breaking tenacity and theelongation at break of blending yarns are not much different and the breaking tenacity of blending yarn is between that of pure flame retardant viscose yarn and pure flame retardant acrylic yarn.
