Embodiment 1

[0013] A iron gray dyeing method of fox velvet described in this example, put water and fox velvet into the dyeing vat, heat up to 40°C, add auxiliary agent, keep warm for 10min, then add dye, keep warm for 10min; at a speed of 1°C / min Raise the temperature to 90°C, keep it warm for 40 minutes, clean it, drop the temperature to 40°C, add soda ash, quickly raise the temperature to 80°C, clean it, and drop the temperature to 40°C, add soaping agent, quickly raise the temperature to 90°C, clean it, and the temperature Lower it to 40°C, add softener, keep warm for 20 minutes, and finally take it out of the cylinder.

[0014] Described dyestuff comprises reactive yellow 4RFN, reactive red B-2BF, reactive dark blue M-2GE, and wherein the consumption of reactive yellow 4RFN is 0.82% of the quality of fox velvet, the consumption of reactive red B-2BF is 0.58% of the quality of fox velvet, The dosage of active dark blue M-2GE is 0.835% of the mass of fox hair.

[0015] The consumption...

Abstract

The invention relates to the technical field of dyeing, in particular to an iron grey dyeing method of fox down, comprising: placing water and fox down in a dye vat, heating to 40 DEG C, adding an aid, holding the temperature for 10 min, adding a dye, and holding the temperature for 10 min; heating at a speed of 1 DEG C / min to 90 DEG C, holding the temperature for 40 min, cleaning, lowering the temperature to 40 DEG C, adding pure caustic soda, heating fast to 80 DEG C, cleaning, lowering the temperature to 40 DEG C, adding a soaping agent, heating fast to 90 DEG C, cleaning, lowering the temperature to 40 DEG C, adding a softening agent, holding the temperature for 20 min, and removing from the vat. The iron grey dyeing method of fox down obtained herein enables color fastness of the dyed fox down to reach level 3 without dyeing defect, a production process is relatively short, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to an iron gray dyeing method of fox velvet. Background technique [0002] After the existing fox velvet is dyed, its color fastness is relatively poor, and the problems of uneven dyeing and colored flowers are prone to occur. Contents of the invention [0003] The purpose of the present invention is to provide a kind of good color fastness in order to solve the deficiency of above-mentioned technology, the iron gray dyeing method of the evenly dyed fox down. [0004] In order to achieve the above object, the iron gray dyeing method of a kind of fox velvet designed by the present invention, water and fox velvet are put into dye vat, be warmed up to 40 ℃, add auxiliary agent, keep warm for 10min, add dyestuff again, keep warm for 10min; Heat up to 90°C at the speed of ℃ / min, keep it warm for 40 minutes, clean it up, drop the temperature to 40°C, add soda ash, quickly raise the temp...
