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.

Key words: CK-37, spectral property, basalt fiber, glass fiber, tinting
