摘　　要：在织物表面微滴喷射打印沉积成形微细导电线路中,明确微滴在织物表面碰撞和渗透过程是成形高质量导电线路的前提。采用试验研究的方法,在喷射系统可控喷射条件下,对微滴与织物表面的碰撞、铺展及渗透过程进行图像采集及动态过程研究。结果表明:微滴在织物基板表面的碰撞过程与固体基板类似,几乎未发生渗透现象;由于毛细压差的作用,不同织物在不同时间段内的渗透速率急剧增大,出现快速芯吸现象,且织物经纬密度越小,芯吸效果越明显;微滴在织物表面的扩散形状由织物的组织结构决定,扩散面积与织物润湿性有关,随润湿性的减弱而减小。During deposition forming fine conductive circuit on fabric surface, micro-droplet jet printing droplets collision and penetration process on fabric surface are determined to premise to form a high quality conductive circuit. Using experimental research methods, under the controlled injection condition of the injection system, the dynamic peocess of the droplets collision, deposition and penetration on the fabric surface were captured and studied. The results show that droplets collision on the fabric substrate surface is similar to the solid substrate, and penetrantion phenomenon almost does not occur. As the effect of capillary pressure difference, different fabrics in different periods have penetration rate increasing sharply, rapid wicking phenomenon appears. The small the thread count, the more obvious wicking effect. Droplets diffusion shapes on the fabric surface are determined by the structure of the fabric. The area of diffusion is related to fabric wettability, and it decreaes with weakened wettablity.
