Photochromic silky comfort knitted underwear fabric and preparation method thereof

Abstract

The invention discloses a preparation method of photochromic silky comfort knitted underwear fabric. The preparation method of the photochromic silky comfort knitted underwear fabric includes the steps that (1), nano bamboo carbon fibers and jute fibers are put in a 3-5 wt% naphthopyran solution with acetone as a solvent to be soaked, the fibers are dried, and bamboo-jute mixed fibers are prepared; (2), the prepared bamboo-jute mixed fibers and color-variable photosensitive fibers are mixed in proportion, the fibers are plied and twisted, yarn is prepared, and color-variable photoelectric mixed yarn is obtained after treatment is completed; (3), the color-variable photoelectric mixed yarn serves as surface yarn, polyamide filament and spandex filament core-spun yarn serves as ground yarn,and the photochromic silky comfort knitted underwear fabric is prepared. The photochromic silky comfort knitted underwear fabric prepared through the method is soft in gloss, smooth and glutinous in hand feeling, light and elegant, and the crease resistance, tensile performance and compression elasticity of the underwear fabric are improved; different colors can be shown at different environment temperatures, and therefore the color-variable effect is achieved.
