The invention provides a
staining method for
aramid fiber. The
staining method comprises the steps of preprocessing, preshaping,
staining, reduction clearing, color fixing, soft
processing,
drying, shaping, calendaring and rolling. According to the staining method,
DEET is added in to serve as a dye carrier, and the staining effect and efficiency are improved; meanwhile, substitute alkali is adopted to replace a conventional soda substance, and not only is the usage amount decreased, but also the color fixing effect is enhanced to enable the washability of the
aramid fiber is further enhanced; the reduction clearing and color fixing processes are added, and therefore the staining fastness is good; green and environmental-friendly non-
formaldehyde TCD-R is adopted in the color fixing process, the
fiber is dried step by step after color fixing, and therefore the firmness of the fiber is greatly improved; the soft
processing process is added, the color fastness and softness of fabric are improved, the roughness of the fabric is reduced, and therefore the fabric is fluffy and rich in elasticity.
