Supercritical CO 2 dyeing technology can make synthetic fibers obtain gratifying Color, and step into
To pilot scale, test manufacture stage.But the supercritical CO 2 dyeing technology of cotton fiber fails to have breakthrough always, one of them
Reason is that many hydroxyls that cotton fiber surface is present are easy to produce hydrogen bond, and these hydrogen bonds constitute huge hydrogen bond grid, directly
The formation of the crystal structure of densification is result in, makes cellulose fibre be difficult to dye.Although swelling by cellulose can be destroyed
The hydrogen bond of cellulose, increases the slip of cellulose molecular chain, makes cellulose activation, it is easy to upper to contaminate.But supercritical carbon dioxide is situated between
Matter itself simultaneously cannot destroy the hydrogen bond of cellulose, make cellulose swelling, and the dyeing of cotton fiber in supercritical carbon dioxide is stranded very much
It is difficult.So some compounds that can destroy hydrogen bond in supercritical carbon dioxide, are must be added to, effective swelling supercritical carbon dioxide
Cotton fiber in fluid.And the hydroxyl that cotton fiber surface is present is easy to produce hydrogen bond with hydrone, and this causes fiber surface meeting
One layer of water-bearing layer is formed, prevents supercritical carbon dioxide to the infiltration of cotton fiber and dyestuff to fibre-bearing diffusion inside, so needing
The contact between supercritical carbon dioxide fluid and cotton fiber can be effectively increased using some compounds that can destroy hydrogen bond.
