Considerable attention has been garnered by the practical application of conductive silver paste in smart textiles, but it is also acknowledged that challenges are presented, primarily attributed to the surface roughness and diverse structural organization of textiles. Moreover, the stretchable conductivity of silver paste on textiles can be affected by external forces such as wearing and movement during usage. To address this issue, a polyol synthesis method was employed in this study to successfully prepare silver nanowires, and silver particles of different sizes were selected to prepare silver paste. Various proportions of nano silver wires were added to the silver paste, which was subsequently applied to elastic knitted fabric using screen printing technology. SEM, FTIR, and other analyses were conducted. Simultaneously, the conductivity of the textiles after stretching was evaluated by conducting resistance tests on textiles stretched to different lengths. The results indicate that when 2wt% of nano silver wires are added to the silver paste and applied to textiles, the surface resistance of the fabric can still be maintained below 100Ω/dm when the fabric is stretched to 60%. It is indicated that the stretchability of the silver paste can be effectively enhanced to meet the stability requirements of smart textiles by adding silver nanowires to the silver paste.
