Abstract:

In order to further expand the application scope of luminous embroidery thread and improve the luminous intensity of luminous computer-embroidery fabric,  a computer-embroidery fabric which can emit the light with a long afterglow effect during the night was prepared by using Wilcom 9.0 software and FuYi computer embroidery machine. The influences of three kind of process parameters of stitch spacing, stitch speed and excitation time on afterglow brightness of fabric were investigated by using the Box- Behnken method, and a response surface model of afterglow brightness was obtained by designing the orthogonal test with the above three factors. The results indicated that compared with stitch spacing and stitch speed, the excitation time has a remarkable influence on afterglow brightness of fabric. The optimum technological conditions are: excitation time of 20 min, stitch length of 4.5 mm and stitch spacing of 0.4 mm, and the afterglow brightness under the suitable conditions is 1.6215 cd?m-2.

Key words: computer-embroidery fabric, luminous embroidery thread, afterglow brightness, response surface methodology
