摘要

Photochromic textiles have been used in the sensible materials (sensor) in the smart textiles and esthetic materials in the fashion industry due to the color changing properties, which gives immense inspiration to prepare photochromic textile materials, in this regards we take more attention to prepare the mass dyed polypropylene filaments with photochromic pigments. Metallocene polypropylene filaments were doped by different concentration of photochromic pigment. In our experimental work, the optical and mechanical properties of these multifilaments depending on their drawing ratio were investigated. The photochromic pigment used was 5-Chloro-13-dihydro-133-trimethylspiro[2H-indole-23-(3H)naphtha [2,1b](14)oxazine]. Regarding the optical properties, our investigation confirms the known effect of the primary reflectance on the depth of shade of colored multifilaments as shown by linear increase in difference in optical density with increasing ratio of fineness.
