Embodiment
Below by embodiment, the present invention is made to specific description:
Embodiment mono-
Sheep known for its fine thick wool skin is carried out to pre-treatment to the present embodiment and tanning penetrates and dyeing colour flower step.Pretreatment process comprise rawhide return fresh, pelt board matter is fixed, pickling and four steps of green-shaving.Tanning penetrates that operation comprises enzyme bating, plate matter penetrates and tanning, comprehensively reduce three steps.Below respectively above-mentioned steps is described in detail:
1, rawhide returns fresh.Rawhide is soaked as in water 24 hours.Add afterwards enzyme-containing detergent to wash skin.Enzyme-containing detergent can improve the perviousness of the enzyme of hair matter, plate matter in follow-up process for tanning and penetrate dynamics.
2, pelt board matter is fixed.30 sheep known for its fine thick wool skins are put into 140L underground water.Add 60.0-71.4g/L salt, 65.0-85.7g/L Sodium sulfate anhydrous.min(99), is adjusted to 1.5-2.0 by pH value, and 25 ℃-30 ℃ of constant temperature, stir once every 1h.Treatment time is 20 to 24 hours.This pelt board matter fixing step can strengthen the tensile strength of fur.For further improving pelt board matter fixed mass, can also in the solution of pelt board matter fixing step, add salt, Sodium sulfate anhydrous.min(99), be 75g/L by the concentration adjustment of salt again, by the concentration adjustment of Sodium sulfate anhydrous.min(99), is 90g/L, add again 0.2ml/L sulfuric acid, pH value is adjusted to 1.5-2.0.38 ℃-40 ℃ of constant temperature, the treatment time is 12 to 24 hours.
3, green-shaving.In order to improve dye liquor, penetrate the ability of fur, utilize water shovel to carry out skiving to the plate matter of the fur after pelt board matter is fixing, remove oil reservoir, the pachydermia portion of plate matter.The Thickness Ratio tradition skiving thickness of skiving doubles, and the thickness of pruning accounts for 10% to 20% of dermatotome total thickness.
4, enzyme bating.Fur after shaving is put into 140L underground water, and adding model is 537 domestic aspartic protease 5U/mL, salt 35.7g/L, and Sodium sulfate anhydrous.min(99) 42.9g/L, sulfuric acid 1.9ml/L, is adjusted to 3-3.5 by pH value, constant temperature 38-40 ℃.Treatment time is 12 to 24 hours.
5, plate matter penetrates and tanning.Fur after enzyme bating is processed is pulled out, put into 140L underground water, adding model is 537 domestic aspartic protease 0.3-5U/mL, model is the white tanning agent 2-4ml/L of PU-08, soda ash 4.0-5.7g/L, salt 25.0-35.7g/L, Sodium sulfate anhydrous.min(99) 35.0-42.9g/L, pH value is adjusted to 3-3.5, constant temperature 38-42 ℃.Treatment time is 44 to 48 hours.
6, comprehensively reduction.Fur after tanning is processed is pulled out, puts into 140L underground water, and 38 ℃ of constant temperature, add 2.9g/L salt, 3.6g/L Sodium sulfate anhydrous.min(99), and 3.6g/L sulfate of ammoniac, 1.4g/L alum, 0.2ml/L sulfuric acid, is adjusted to 3-3.5 by pH value.Treatment time is 12 to 24 hours.
After comprehensive reduction, fur is pulled out, after drying, drying, completed whole tanning and penetrated technique, can be for post-treatment operations such as printing and dyeing patterns.
In the above-mentioned course of processing, this pelt board matter fixing step can improve tensile strength or the elasticity of fur, thereby makes the follow-up green-shaving step more dermatotome of can pruning compared to existing technology, thereby improves the penetrativity of dye liquor.This plate matter penetrates and tanning step is used aspartic protease and white tanning agent simultaneously, make molecules in solution, lake participate in reaction, oil and fat system in disintegration, decomposition dermatotome, greatly improved the ability that owse decomposes interfibrillar substance in dermatotome, the spacing of corium fabric in dermatotome is increased, thereby improved dermatotome absorption dye liquor, and made dye liquor penetrate the ability of dermatotome.This plate matter penetrate and tanning step in, the consumption of this aspartic protease directly in the follow-up dyeing of impact dye liquor adsorb and penetrates the ability of dermatotome, the consumption of aspartic protease is more, in dermatotome, the spacing of corium fabric is just larger; But, if acidic protein enzyme dosage is too much, for example, having surpassed the consumption in enzyme bating step, the defects such as dermatotome, depilation may be damaged.So in the present embodiment, the consumption of aspartic protease is the 6%-100% of the consumption in enzyme bating step.
In follow-up dyeing colour flower step, the ability that penetrates dermatotome due to dye liquor is stronger, the dye liquor contacting with specific region fur will be effectively adsorbed on the dermatotome being connected with this fur, and constantly to dermatotome, permeate, this just makes have considerable dye liquor to be limited on the specific region of dermatotome in dyeing process, thereby effectively extended dye liquor in printing and dyeing flower process, contacts and prints and dyes the time spent with specific region fur.Due to the prolongation that printing and dyeing are taken time, dyeing efficiency is promoted naturally.
Understandable, formula and the condition of above-mentioned pre-treatment, enzyme bating and comprehensive reduction step can also, for the character of processed fur, be selected other conventional formula or the condition of fur circle, and can not affect reaching of the object of the invention.This plate matter penetrate and tanning step in can also select the aspartic protease of other models, wherein, the consumption of aspartic protease is limited with the consumption being no more than in enzyme bating step.This plate matter penetrate and tanning step in can also select other types tanning agent to replace white tanning agent, as long as this tanning agent can complete the tanning to fur.
