磁性纤维针织物表面磁场的分布

磁性织物的保健功效通过其表面磁场作用于人体而发挥，且受表面磁场强度、方向及分布特征共同影响。本研究对双层磁性织物及磁性织物与非磁性织物在不同配置方式下的表面磁场进行探究，并用MATLAB将织物表面磁感应强度分布情况绘制成三维图形进行可视化表达。研究表明：磁性织物表面磁场强度较弱，介于0.02~0.05mT之间，分布极不均匀，区域间差异较大；双层磁性织物叠加后表面磁场强度显著增加，区域间差异随机地增大或减小；非磁性织物覆盖磁性织物或将磁性织物置于非磁性织物夹层中后，表面磁场强度显著减弱，区域间差异减小，减弱程度取决于非磁性织物的厚度；磁性织物覆盖非磁性织物后，表面磁场不变。

Surface magnetic field distribution of magnetic knitted fabric

The health care function of magnetic fabric acts on human body through its surface magnetic field. Its effect is affected by the intensity, direction and distribution of the surface magnetic field together. This study has explored the surface magnetic field of double magnetic fabrics and the fabrics in different configuration methods between magnetic fabric and non-magnetic fabric. In addition, MATLAB has been used to draw the distribution of surface magnetic induction intensity into three-dimensional graphics visually. The results of study show that the surface magnetic field strength of magnetic fabric is weak and it is usually between 0.02mT-0.05mT. The distribution is extremely uneven and varies in different regions. It has also been found that the surface magnetic field intensity of double magnetic fabric increases significantly while the differences in regions can increase or decrease randomly. If magnetic fabric covered by non-magnetic fabric or placed between layers of non-magnetic fabric, the surface magnetic field intensity weakens significantly while the differences in regions decrease. The weakening extent mainly depends on the thickness of non-magnetic fabric. The surface magnetic field will not change when non-magnetic fabric covered by magnetic fabric.
