Additive mixture ofcolortrichroism is red,green and blue,subtractive mixture,as its complementary colors,is cyan,ma genta and yellow,thatis the dyestuff trichroism.
It is an important organic chemical material and widely used in many fields, dyestuff, medicine, detonator, spicery and rubber-vulcanize accelerant etc.
The principal prupose of this study is on nanosizing the disperse dyestuffs to colourize the fabric made of polyester super-micro fibers and to improve its dyeing properties.
A novel dust proofing agent for dyestuff was prepared by the addition of industrial fatty acid and glycol epoxide, which could produce a kind of emulsor.
Buy Chemicals Buy Chemicals We buy chemicals like caustic soda, soda ash, alum, sodium hydrosulphite, paint chemicals, cosmetic chemicals and dyestuff such as vat dyes, disperse dyes, acid dyes.
Extract dyestuffs such as mineral and plant,etc. from the nature, will call as five colors bluely and greenly, yellowly, redly, whitely, blacklily, and then seize other after the five color mixture.
The steam engine, the telegraph, the telephone, the trolley car, dyestuffs, medicines, explosives — these are the fruits of science, and without these science is of no avail.
