Description
Technical field
The present invention relates to the field of bleachinging and dyeing, especially relate to a kind of method that fleece chromium soap pollutes of removing.
Background technology
Chromic salts is the essential substance of tan leather and fur coat.But in making the process of chromic salts tanning fur, if misoperation, for example, pH(potential of hydrogen during tanning) on the excess Temperature of too high, tanning or fleece, grease pre-treatment is thorough etc., chromic salts can produce precipitation or strengthen with fleece bonding force, forms chromium soap, and is attached on fur.General chromium soap comprises the materials such as chromium hydroxide, chromium sesquioxide.
Because chromium soap is water-fast, be therefore difficult to water it is got rid of.Due to adhering to of chromium soap, fur by tanning after, fleece there will be greening and lacklustre problem, affects its use value and economic worth, this is called as chromium soap and pollutes.
Now, the chromium soap that does not also have a kind of method can effectively remove on fleece pollutes.
Summary of the invention
The present invention proposes a kind of method that fleece chromium soap pollutes of removing, the chromium soap that can effectively remove on fleece pollutes.
In order to achieve the above object, technical scheme of the present invention is achieved in that
Remove the method that fleece chromium soap pollutes, comprising:
In the acidic solution being formed by water, oxalic acid and fatty alcohol-polyoxyethylene ether, fleece is processed; Wherein, in every 1000g water, the content of fatty alcohol-polyoxyethylene ether and oxalic acid is respectively 1g-2g and 1g-1.5g;
Fleece water after processing is washed;
In the basic solution being formed by water, sodium carbonate and fatty alcohol-polyoxyethylene ether, fleece is processed; Wherein, in every 1000g water, the content of fatty alcohol-polyoxyethylene ether and sodium carbonate is respectively 1g-2g and 1g-3g;
Wherein, while removing the pollution of fleece chromium soap, the mass ratio of the water in fleece and acidic solution is 1:15-1:25; The mass ratio of the water in fleece and basic solution is also 1:15-1:25.
Preferably, in the described acidic solution being comprised of water, oxalic acid and fatty alcohol-polyoxyethylene ether, fleece is processed, needed temperature is between 20 ℃-35 ℃.
Preferably, in the described acidic solution being comprised of water, oxalic acid and fatty alcohol-polyoxyethylene ether, fleece is processed, needed temperature is 32 ℃.
Preferably, in the described acidic solution being comprised of water, oxalic acid and fatty alcohol-polyoxyethylene ether, fleece is processed, required time is 40 minutes-60 minutes.
Preferably, in the described basic solution being comprised of water, sodium carbonate and fatty alcohol-polyoxyethylene ether, fleece is processed, needed temperature is between 40 ℃-45 ℃.
Preferably, in the described basic solution being comprised of water, sodium carbonate and fatty alcohol-polyoxyethylene ether, fleece is processed, needed temperature is 45 ℃.
Preferably, in the described basic solution being comprised of water, sodium carbonate and fatty alcohol-polyoxyethylene ether, fleece is processed, required time is 30 minutes-50 minutes.
By above description, can be found out, the present invention has the following advantages:
Because the composition in chromium soap comprises the compound of multiple chromium, when the fur being polluted by chromium soap is carried out to acid treatment, oxalic acid can generate water-soluble chromium+oxalic acid with can react with the chromium cpd of acid-respons in chromium soap, and for example oxalic acid can react with the chromium hydroxide in chromium soap.When the fur being polluted by chromium soap is carried out to alkaline purification, sodium carbonate can with in chromium soap, can react with the chromium cpd of alkali reaction, generate water-fast throw out, and the throw out generating is owing to being in water, can not be attached on fur.And owing to containing a lot of greases on fleece, grease has very strong adsorption to chromium hydroxide, by fatty alcohol-polyoxyethylene ether, fleece is carried out to skimming treatment, avoided the absorption of chromium soap.By acid treatment, combine with alkaline purification, the chromium soap of effectively removing on fleece pollutes.
