(3) each prison spends index
Dye of acid dye, oxidation, TIPPING DYES and BRUSHING DYES in wool effect of printing be gettinged on differs, if use acid dye, because the condition such as temperature cannot satisfy his to ask, dye cannot diffuse fiber interior produces tie, and can adsorptive in wool fibre surface, each prison spends index not to talk to go up at all, reason is unfavorable use, oxidation dye, TIPPING DYES can be united in wedlock with wool fibre below microtherm condition, agree with fur printing.
(4) of dye on acquire property
The dye that function Liu catchs on can imprint brunet, conversely, can imprint only light color, the weight of neuter dye is great, amino union divides it and leather fiber outside relying on salt to bolt, still rely on hydrogenous key and Fan Dehua force, because this is OK,imprint with it brunet.
