(Skip here black meaning a certain number of words. . . . . . ..
Optical principle
The black that we see, tell in optical angle, because they absorbed all visible light,be.
The wavelengh of the electromagnetic wave that the eye of average person can feel is between 400 ～ 760nm, but still a few people can feel wavelengh to be in about the electromagnetic wave between 380 ～ 780nm. SO, the black object that we see, it is the substance that can assimilate the electromagnetic wave between 380-780nm. (detailed sees figure below)
Can assimilate the substance of all visible light, wanting also is very mysterious.
Black dye
Cut a theme, want to acquire fiber, yarn or fabric into black, need black dye of course. So, does colored suit to you can make the material of dye again after all on the world? Regretful is: Up to now, only two dye can say to go up is black dye, it is aniline only black (C.I. Solvent is black 5) , another is vulcanization black BRN (C.I. Vulcanization is black 1) . Divide this beyond, active dye is black, dispersive dye acid dye is black, black it is etc answer deserve to come out.
So small make up chose this title: Before black not be black!
Below with active dye black for exemple, talk about black dye answer match, in active dye, give priority to the C.I that wants the system intermediate with H acid. Active is black 5 (weigh black B, black B to wait again) , it is active black go all out in dye with most. Tell from shade angle, 5 black B are more accurate saying is dark blue, to get pitch-black black, active dye answer match a technique subsequently and come.
Original active is black answer matching is to use B and active orange photograph to go all out, differ because of the index such as the SERFMIWF of orange dye and B bigger, in coloring process appear easily to be not stabilized, spelled active again later red.
Again later, because the solid of 5 black B is lubricious rate is lower, prison degree opposite poorer, better to obtain active black dye, dye company begins to study with other active dark blue replaces 5 B, cost rises relatively, but prison degree with the gender valence comparing also rose.
Manage together, mix blackly dispersedly spell a principle to be the same as active black, because small make up knowledge finite tell about no longer.
Use problem
1, because black dye is answer match those who go all out to mix, accordingly, in the choice of actual dye recipe, black dye spells orange to be decided than spelling Huang Gengwen, small make up so because,consider as: If go all out,fizzle out, it is so at least 4 went all out, what dye goes all out is more, stability is poorer, should be this truth?
2, the prison of black dye is spent opposite poorer, because color is too deep, bath, attrition, insolation is waited a moment prison degree poorer, want to achieve taller prison to spend, in dye choice, craft is made, can undertake improvement on aftertreatment auxiliary choice, because this topic content is too much, did not introduce in detail first.
3, pitch on same a dress, I can buy black as far as possible, the reason has 2: Fabrics cost of black tall, black is not easy dirty. . . . . . .
4, the more topic that is aimed at black, welcome everybody to leave a message interactive, recently about " the problem is vaccinal " , " crock of manganese steel hot water " etc brush screen, the heart of these businessmen is pitch-black and pitch-black for certain!
