Abstract: This paper finds the most suitable chromogenic reagent,the chromogenic ratio,the chromogenic temperature and the chromogenic time of CK-37 with ultraviolet visible spectrophotometer in the research of spectral property.It also applies visualisation method on the tinting of basalt fiber and glass fiber.The result shows:(1)The CK-37 is easily soluble in acetone and ethanol;(2) hydrochloric acid is the most suitable chromogenic reagent,and the effect will increase when the acid concentration increases,and the equimolar ratio with hydrochloric acid is 1∶2(1∶1 with oxalic acid),and 25 ℃ is the most suitable temperature,the experiment also shows the shortest chromogenic time is 10 minutes;(3)the stained fiber is bright in color and the color does not fade in water,and the result also shows that the stained fiber could have endurance for acid and alkali.
