摘要
以阻燃粘胶纤维和腈氯纶为原料,按照不同的混纺比制备了阻燃机织物.采用垂直燃烧法、极限氧指数(LOI)法和强力仪对织物的阻燃性能和力学性能进行测试分析.结果表明:随混纺织物中阻燃粘胶纤维含量的增加,织物的续燃时间和阴燃时间均缩短,而损毁长度大大增加,织物的LOI值下降,织物的经纬向断裂强度及断裂伸长率均下降,说明混纺织物中阻燃腈氯纶含量对混纺织物性能的贡献要大于阻燃粘胶纤维.
A kind of fire retarded woven fabric is prepared with the raw materials of modacrylic fiber and flame resistant viscose fiber with different blending ratios.The fire retardant property and mechanical performance of the fire retarded woven fabric are tested by vertical flammability test,limiting oxygen index（LOI） and universal strength tester.The results show that with the increasing of fire retarded viscose fiber content in the blended fabric,the afterglow time and afterflame time all shorten,the damage length increases greatly,the LOI values,the longitudinal and horizontal breaking strength and elongation of the blended fabric all decrease,which indicates that the influence of content of the modacrylic fiber on the property of the blended fabric is greater than that of fire retarded viscose fiber.
