Embodiment 1

[0015] 1. Take 1 catties of long colored feathers and soak in 25 catties of activator, that is, FeSO with a concentration of 1%. 4 In the aqueous solution, soak for 3 hours at a temperature of 20°C;

[0016] 2. Take out the feather soaked in the activator, drain the water, and immerse 25 catties in a hydrogen peroxide solution with a temperature of 30°C and a concentration of 5% for 4 hours;

[0017] 3. Take out the feathers, soak them in 25 catties of dilute hydrochloric acid with a concentration of 0.5% at room temperature for 10 minutes, drain them, wash them with water, and finally dry them at 35-40°C to get the finished white feathers.

Embodiment 2

[0019] 1. Take 1 catties of colored long flake down and immerse in 20 catties of activator, that is, FeSO with a concentration of 2%. 4 Soak in an aqueous solution at a temperature of 25°C for 2 hours;

[0020] 2. Take out the down soaked with the activator, drain the water, and immerse 20 catties in a hydrogen peroxide solution with a temperature of 35°C and a concentration of 6% for 3 hours;

[0021] 3. Immerse 20 catties of dilute hydrochloric acid with a concentration of 0.8% at room temperature for 30 minutes, drain and then rinse with water, and finally dry in the sun to obtain the finished white feather.

Abstract

The present invention is fast decolorizing and whitening method of color feather and down. FeSO4 is adopted as the bleaching activator for oxygen bleaching decolorizing of color feather and down at 20-25 deg.c, and dilute hydrochloric acid solution is then used in reducing Fe3+ ion before clear water washing. The present invention has simple technological process, and can decolorize color feather and down effectively, and the treated feather and down is fluffy and has the original state maintained and no damage.

Description

technical field [0001] The invention relates to a method for rapid decolorization and whitening of colored feathers and down. Background technique [0002] Feather belongs to protein fiber, and the surface of feather fiber is covered with a layer of cell membrane composed of water-insoluble sterols, waxes and triphosphates, all of which are insoluble organic matter in water, and there are many gaps and cavities inside feather fiber, making feather The density of the feather is very small, and these are the factors that cause the difficulty of decolorization of colored feathers. [0003] At present, my country mainly uses alkali method to decolorize colored feathers and eider down, as disclosed in the "Colored Feather Decolorization Research" article in the 1st issue of "Jiangsu Chemical Industry" magazine in 1991, using 0.5% lye to soak feathers for 24 hours, 1 %H 2 o 2 Soaking for 16-18 days is said to achieve feather decolorization, but this process is not suitable for l...
