Abstract
A kind of fur non-salt composite tanning technology complete processing is characterized in not using neutral salt in whole tannery; Increase " soaking aldehyde " operation; In " pickling " operation, add Tai-Ace S 150; Interpolation sodium phthalate and two Whitfield's ointment methane are made auxiliary agent in " tanning " process.By the fur finished product of above-mentioned composite tanning technology processes soft and fullly, in light weight, water-fast wash, do not lose hair or feathers, not drift sand, help dyeing, it is big to go out the skin rate, simultaneously this technology has also alleviated the pollution to environment of neutral salt and chrome tanning liquid, is a kind of advanced composite tanning technology technology.
Description
The invention belongs to fur manufacturing technology.A kind of composite fur process for tanning that does not use neutral salt (salt, saltcake) of saying so in more detail.
Fur tanning method with bibliographical information commonly used at present mainly contains following four kinds:
One, chromic tanning:
Chromic tanning is a kind of common traditional tannage, and most of fur manufacturing factory still continues to use this method.It is in the solution that contains neutral salt (salt, saltcake), by chrome tanning agent with the effect of fur hide fiber, combination, thereby change the character of pelt, make dermatotome have certain physical and chemical performance, reach dermatotome softness, easily storage, plastic purpose.The shortcoming of this method is that the skin rate little, and dermatotome is thicker, and fleece particularly dermatotome often has color.Contain a large amount of neutral salt and chromium ion in the chroming waste liquor, will cause more serious pollution.
Two, aluminum tannage:
Aluminum tannage also is a kind of tannage of early developing, and is in light weight with the fur that it processes, the plate face is pure white, it is big to go out the skin rate.Though this method has been avoided the pollution of the chromium in the waste liquid, but still has used a large amount of neutral salt, still has more serious pollution.Also exist aluminium salt and combine insecure, poor stability with collegen filament, not water-fast washing damaged the shortcoming of fleece simultaneously;
Three, other tannages:
Comprise: organic tanning method, oil tanning, synthetic tannage etc.They all use neutral salt, and more serious pollution is arranged.
Four, combination tannage:
Combination tannage is one of main method of domestic and international widespread usage, and it is the deficiency that remedies single tannages such as aluminum tannage, chromic tanning, and known combination tannage has: aluminium chromium combination tannage, aldehyde aluminium combination tannage etc.Though the dermatotome quality of fur has had significant raising, but still has shortcomings such as drift sand, depilation, and is especially to the pollution problem of environment, still more serious.
For reducing the pollution of fur industry to environment, overcome the shortcoming that current combination tannage still exists, the present invention proposes a kind of aldehyde, aluminium, chromium composite tanning technology technology of in fur tanning processing, not using neutral salt.This technology can eradicate fur produce in salt, saltcake to the pollution of environment, reduce the pollution of chromium, can also improve simultaneously and skin rate and fur final product quality.
The flow process of non-salt composite tanning technology technology of the present invention sees accompanying drawing one for details, and its principal feature is as follows:
One, in whole tannery, do not add neutral salt from start to finish.
The effect of neutral salt is to promote that returning of dermatotome is bright, prevents the dermatotome swelling that causes owing to sour effect.This technology is used instead to increase after removing neutral salt and is soaked the aldehyde operation and reduce sour consumption, adds sour number of times, and modes such as reduction liquid temperature replace.
Two, after " enzyme bating " operation of traditional process for tanning, increase " soaking aldehyde " operation.
The purpose of soaking aldehyde is to stop rapidly because drift sand, the depilation phenomenon that the continuation effect of proteolytic enzyme causes avoided owing to the dermatotome swelling that is caused under the situation of no neutral salt effect.Simultaneously, the fur dermatotome is carried out aldehyde give tanning and also help in the tanning course of processing, promote and suitable post-treatment condition is provided the protection of fur.
Three, do not use neutral salt in " pickling " operation after " soaking aldehyde " operation, reduce the consumption of acid and add a certain amount of Tai-Ace S 150.
Add Tai-Ace S 150 and can avoid " acid is swollen " on the one hand, can play certain filling and give the effect of tanning dermatotome on the other hand.
Four, interpolation sodium phthalate and two salicylic acid methane are made auxiliary agent in " tanning " operation after " pickling " operation.
The aluminum tanning agent that the interpolation sodium phthalate is made sequestering agent can partly replace chrome tanning agent, thereby has reduced the consumption of chromium sesquioxide, adds two salicylic acid methane and can form chromium complex with trivalent chromium, has increased light stability.
Now the concrete processing condition with non-salt composite tanning technology technology of the present invention are described below:
The prescription of " soaking aldehyde " of the present invention operation employed " soaking aldehyde liquid " is:
Formaldehyde: 3～8g/L
Peregal or other similar permeate agent: 0.5～1g/L
Processing condition are: liquor ratio coefficient: 14～20; Liquid temperature: normal temperature; Time: 20 ± 4 hours.
The prescription of " pickling " of the present invention operation employed " pickling liquid " is:
Tai-Ace S 150: 1～3g/L, sulfuric acid: 0.5～2.5g/L,
Peregal or other similar permeate agent: 0.5～1g/L.
Processing condition are: the pickling temperature: 30～35 ℃, and the time: 20～24 hours.
The prescription of " tanning " of the present invention operation employed " tanning solution " is:
Chromium sesquioxide: 0.2～0.4g/L
Tai-Ace S 150: 2～5g/L, talcum powder: 10～20g/L
Sodium phthalate: 1.5～4g/L,
Peregal: 0.5～1g/L
Two salicylic acid methane: 0.5～2g/L,
Sulfuric acid: 1～2.5g/L, sodium bicarbonate: 1～3g/L
Alkali face: 1.5～2g/L
Processing condition are: the liquor ratio coefficient: 14～18, and 35 ℃ of temperature (during hypodermis),
Time: 70 hours
Its concrete operations condition is: the beginning controlled temperature is 35 ℃, behind pH, 3.0～3.3 12 hour, is warming up to 39 ℃; Be warming up to 41 ℃ and transfer pH to 3.8 after 24 hours with sodium bicarbonate; Be warming up to 42 ℃ after 36 hours; Be warming up to 43 ℃ after 48 hours, and transfer pH to 3.8 with the alkali face; Go out skin after 70 hours.
The advantage of non-salt composite tanning technology technology of the present invention is:
1, eradicate the pollution of neutral salt to environment,
2, reduced the consumption and the pollution of chromium,
The amount of the chromium sesquioxide that uses only for 1/2 to 1/3 of general chromic tanning, has alleviated the pollution of chromic salts to environment greatly in this technology.
3, improved the fur final product quality.
Use the fur dermatotome of this processing method tanning soft and full, water-fast washing, shrinkage temperature has solved problems such as drift sand and depilation simultaneously up to more than 90 ℃.
4, improved product percent of pass
The product qualification rate reaching of using technology tanning of the present invention is more than 98%, and the aluminum tannage qualification rate is about 90%, and chromium aluminum tannage qualification rate is about 93%.
