Abstract
A method for preparing and bleaching special animal's fine hair with organic solvent includes such technological steps as anti-shrink treatment, neutralizing with the mixture of alkali and peroxide, washing with clean water, immersing clean fine hair in mordant of organic solvent, washing and decolouring. The strength, brightness and elasticity of the fine hair treated by said method are greatly increased without yellowing.
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, ten preciousnesses so white, light special fur just seem, 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, this method is on the CN95104454.0 basis, add organic solvent and carry out mordant dyeing, 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, it comprises mordant dyeing, blanching step, it mainly is through matchmaker's dirt with special fur, before handling, bleaching carries out shrinkproof processing earlier, 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 ℃, and the 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, the 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, drying can obtain the fine hair that decolours.Organic solvent is C
