Abstract
The present invention relates to a technological method for manufacturing goose down fur, which mainly improves a tanning method in the technology. Goose down fur is tanned by a formaldehyde tanning solution which comprises formaldehyde, sodium sulfate, sodium chloride, sulphuric acid, sodium bicarbonate and soft water, and then the goose down fur is immersed in a neutralizing solution comprising sulphuric acid, sodium sulfate, sodium chloride and soft water. The processed poultry goose down fur has the advantages of white and soft appearance, moisture and mildew resistance, no yellowing or fluff desquamation, water washing resistance, etc.
Description
The present invention relates to a kind of processing method of making fowl goose down plumage fur coat.
Beasts fur coat manufacturing technology is used widely at present, and aboundresources, cheap poultry geese down fur coat do not grow up so far, its reason is that the molecular structure and the Chemical Composition of geese down skin is different from the beasts fur, so its processing technology is different from the processing technology of beasts fur.In the manufacture craft of geese down skin, tannery is crucial, and it is the principal element that guarantees quality product and the final typing of product.The existing al-tanning solution tanning geese down fur coat that adopts, its product surface is pure white, and is soft, but humidity is easily not mouldy, not ageing-resistant easy flavescence, suede is easily fallen in not anti-storage, and it is not water-fast that to wash easy plate hard.
The objective of the invention is at the problems referred to above, a kind of new process of making the geese down fur coat is provided, mainly be on tannery, to make improvements, it is surperficial pure white that its product is had, and soft, moisture-proof is difficult for mouldy, ageing-resistant non-yellowing, suede is not fallen in anti-storage, the water-fast not hard advantage of plate of washing, and the manufacture craft maturation of geese down fur coat is perfect.
The object of the present invention is achieved like this: the manufacture craft process of poultry geese down fur coat comprises raw hide immersion → fleshing → washing → pickling → tanning → neutralization → degreasing → drying.Its technical characterictic is that the tanning operation is prepared the formaldehyde owse in following component and ratio earlier:
Formaldehyde 1-10g/ liter
Sodium sulfate 20-60g/ liter
Sodium-chlor 30-50g/ liter
Sulfuric acid 1-5g/ liter
Sodium bicarbonate 3-20g/ liter
Soft water, the water yield is skin excessively.
In the said components: formaldehyde has anticorrosion and antioxidant property, can make that skin suede is pure white, diastole, in light weight, humidity, water-fastly wash, do not fall suede; Sodium sulfate has the control dermatotome and produces expansion because of pickling and tanning; Sodium-chlor prevents dermatotome swelling, removes the soluble protein in the dermatotome; It is softening that sulfuric acid has termination, adjusts the effect of pH value; Sodium bicarbonate works the pH value effect of adjusting; Soft water does not contain metal-salts such as calcium, magnesium, reduces the combination reaction that is unfavorable for tanning that produces because of hard water.
Above-mentioned each side is dropped into container for stirring in proportion evenly becomes owse, with after extracting through pickled down skin in the technology, drop in the formaldehyde owse then, per hour paddling once, control condition: 20 °-35 ° of temperature, pH value 7.5-9, time 16-24 hour.
In and operation earlier prepare neutralizer by following component and ratio:
Sulfuric acid 1-10g/ liter
Ammonium sulfate 1-5g/ liter
Sodium sulfate 20-40g/ liter
Sodium-chlor 10-30g/ liter
Soft water, the water yield be skin excessively.
In the said components, sulfuric acid plays flush away and floats off formaldehyde effect on the eider down skin; In the ammonium sulfate energy and the formaldehyde in the dermatotome, make it stable; The effect of sodium sulfate, sodium-chlor all is same as the component of the same race in the owse.
Above-mentioned each side is dropped into container for stirring in proportion evenly becomes neutralizer, tanned eider down skin is extracted put into neutralizer then, per 2 hours paddlings once, control condition: 20 °-30 ° of temperature, pH value 3.5-5.5, time 6-10 hour.
Can add alum 40-60g/ liter in the neutralizer of the present invention, the effect of alum is to make the dermatotome softness, increases extensibility in right amount, makes eider down pure white.
Can add chromium sesquioxide 0.5-1g/ liter in the neutralizer of the present invention, the effect of chromium sesquioxide is to increase moisture resistance, the thermotolerance of dermatotome, suitably increases dermatotome thickness, strengthens tensile strength, makes cortex tight, water-fast washing.
Advantage of the present invention: by the improvement to tannery in the technology, it is pure white, soft that the fur coat with goose down that processes has the surface, humidity, is difficult for mouldyly, ageing-resistant non-yellowing, and suede is not fallen in anti-storage, water-fastly washes not characteristics such as plate is hard.
