【摘要】 镍铁纤维具有磁导率高、吸波频带宽和吸收效率高等特点,可将电磁波的部分能量转变为热掉。采用3种混纺比将羊绒与镍铁纤维混纺得到吸波功能纱线,与纯羊绒纱线按1∶ 3的配比分3层做经、纬纱排列,设计并加工了接结3层织物,改变了表组织中经纬纱的交织频率,测试了织物的吸波性能。结果表明,表层组织为平纹的织物吸波性能最好,表层组织为1上3下斜纹和5枚8飞纬面缎纹的织物吸波性能较弱。更多还原

【Abstract】 Nickel-iron fiber can convert part of the energy of electromagnetic wave into heat energy due to its high permeability,wide frequency band and high electromagnetic wave absorption efficiency.Functional yarns were spun by mixing cashmere and the nickel fiber with three blend ratios,and then stitch woven to 3 layers fabrics with pure cashmere yarn in proportion to 1∶ 3. The interweave frequency of warp and weft yarn in face structure was changed to examine the microwave absorbing property. The results show that the fabric with plain surface structure had best microwave absorbing performance and it decreased when the structure changed to 1/3 twill weave and 8/5 weft faced satin.更多还原
