Nitrate dyeing process for transition color furs

Abstract

The invention discloses a nitrate dyeing process for transition color furs which relates to a fur dyeing process. The nitrate dyeing process for transition color furs is mainly invented for solving the current problem that transition colors dyed on furs are not natural and attractive. The nitrate dyeing process for transition color furs is carried out according to the following steps: fur washing:degreasing agent, sodium carbonate and ammonia are added into water, and a fur is immersed for 2 hours; mordanting: FeSO4 is added into water, and the fur is immersed for 8 to 16 hours; bleaching: bleaching agent is added into water, and the fur is immersed for 6 to 8 hours; deferrization: oxalic acid is added into water, and deferrization time is 3 to 6 hours; reduction bleaching: 2g to 5g of sodium hydrosulfite is added per liter of water, and processing time is 3 to 8 hours; tanning: aluminum retanning is adopted for the whitened fur, chromium retanning is adopted for the fur to be dyed, and after retanning, fatliquoring and drying are carried out; the dyeing method includes dip dyeing, brush dyeing and template dyeing; and dehydration, air-drying, TP oil application and drying are carried out. The advantage is that a transition color which is gradually lightened is dyed on the whole fur.

Description

Technical field: [0001] The invention relates to a dyeing process for furs, in particular to a dyeing process for transitional color furs. Background technique: [0002] Dyeing is a very important process in the fur grooming stage, but not all furs are dyed. Sable, mink, silver black fox, raccoon, lynx and other skins are beautifully dyed and do not need to be dyed. For those fur whose natural color is generalized or not liked by people and needs to be improved and beautified by dyeing, simulation and other techniques, it can be dyed. [0003] The basic methods of fur fading mainly include: alkaline oxidation fading method, which uses oxidants to slowly and melanin to achieve the purpose of uniform fading. When fading with hydrogen peroxide, a certain amount of stabilizer (pyrophosphate) is required to make the fading slow, uniform and deep. . At the same time, the oxidant must be activated in order to effectively interact with melanin. Therefore, a certain amount of acti...

However, because hydrogen peroxide will also have a strong destructive effect on hair keratin when it interacts with pigments, this method generally does more damage to hair, and the efficiency is not very high, the effect is not very uniform, and the fading is not complete.

[0004] In addition, the transition color dyed on a piece of fur is unnatural and unsightly
