Abstract
The present invention relates to a method for bleaching special animal down by using organic solvents, which is mainly comprises the steps that firstly, shrinkage-resistant treatment and neutralization treatment are carried out, and the mixed liquor of alkali and peroxide is used in the neutralization treatment; and after being cleaned with clear water, the cleaned down is soaked into conventional medium dye liquor with organic solvents, and then, the down is cleaned and decolorized. The method has the advantages that the strength and the elasticity of the animal down fibers processed with the method are greatly improved, the brightness is obviously enhanced, and the animal down is difficult to yellow, and the simple, safe and reliable method can greatly reduce the environment pollution.
Description
The present invention relates to method with bleaching special fur by organic solvent
Special fur can be for the wool fibre of weaving beyond being meant sheep, the textiles that adopts this kind fiber to make has special style and takes performance, always is regarded as the textile raw material of preciousness because its fine hair has mostly gently, warm up, soft characteristics and special fur limited amount are died.
Because most of special furs are all coloured, so white, special fur ten preciousnesses that just seem of light color, the present invention is through a large amount of research experiments for this reason, developing a kind of can be the method for white or light fine hair with coloured animal down decolouring, and this method adds organic solvent and carries out mordant dyeing on the CN95104454.0 basis, wash that it is respond well, little to the villus fiber damage.
The object of the invention is; the method with bleaching special fur by organic solvent of development; be on the basis of CN95104454.0, to add organic solvent to carry out the mordant dyeing washing; this method and traditional discoloration method are relatively; it is little to have fibre damage; brightness increases obviously, and is time saving and energy saving, eradicated the favourable protection environment of the anti-lodging reason environmental pollution of chlorination again.
Organic solvent of the present invention prepares the method for bleaching special fine hair, and it comprises mordant dyeing, blanching step, and it mainly is with special fur process matchmaker dirt, carries out shrinkproof processing earlier before bleaching is handled.At first raw material is carried out chloridized, again the special fur after the chloridized is neutralized, special fur is immersed in the mixed solution of the alkali of 0.01-10% and peroxide, liquor ratio is 1: 1-1: 50, temperature is 10-90 ℃, time is 5 minutes-10 hours, after cleaning with clear water again, with special fur by 1: 1-1: 50 liquor ratio is put into the conventional mordanting bath that contains the 0.1-10% organic solvent and is incubated, 30-80 ℃ of mordant dyeing temperature, time is 1-24 hour, drops into to contain in sodium pyrophosphate and the hydrogen peroxide mixed solution again and soaks, fully washing after bleaching again, dry, can obtain the fine hair that decolours.Organic solvent is C
