摘　　要：在试织了4种氨纶含量不同的平针织物,并对其进行前处理及热定型,然后对织物进行基本结构参数、服用性能及弹性回复性测试后发现:改变棉和氨纶的输纱速度可以改变氨纶在织物中的百分含量及线圈长度。氨纶含量越多、线圈长度越长,织物的厚度和面密度越大。织物的折皱回复性更好。相反,织物的透气性越差。织物的弹性回复率和织物中氨纶的含量线性相关,氨纶含量越高,则织物弹性越好。Four plain knitted fabrics with different spandex content are produced. After pretreatment and heat- setting, the basic structure parameter of the fabrics, the wearing performance and elastic recovery properties have been tested. The results indicate that the feeding speed of cotton and spandex can change the percentage content of spandex in fabrics and the loop length. The more spandex it contains, the longer the loop is, and the thicker and denser the fabric will be, and the crease resistance will increase. On the contrary, the air per- meability will decline. The elastic recovery of the fabrics is linearly dependent on the content ofspandex. The more spandex it contains, the better the elastic recovery is.
