通过对磁性纤维的微观形态结构、单丝力学性能及其混纺纱的断裂强力、回潮率和含水率、耐热性和耐酸碱性等性能的测试发现:磁性纤维表面分布着不规则的磁粉微粒;磁性纤维的断裂伸长率较大;磁性纤维湿纺纱的单纱断裂强力接近300 cN,其延伸性较好,回潮率和含水率均较低,耐干热性良好,耐湿热性较差,耐酸不耐碱,尤其不耐强碱。
The microstructure of magnetic fibers, the mechanical properties of monofilaments and the breaking strength, moisture regain and moisture content, heat resistance and acid and alkali resistance of monofilament were tested. The results showed that the surface of magnetic fiber was irregular Magnetic particles; the elongation at break of magnetic fiber is larger; magnetic fiber wet spinning single yarn breaking strength close to 300 cN, its extension is good, moisture and moisture regain are low, good resistance to dry heat, resistance to damp heat Poor sex, acid and alkali, especially intolerant alkali.
