Abstract
The invention provides a processing technology of chromium composited tan cutting broad woolskin, relating to the manufacturing of sheep shearing in shearling industry, in particular to the processing technology of the chromium composited tan cutting broad woolskin. The processing technology adopts specific pickling and lipase adding technology conditions, pretanning technology conditions, compound tanning technology conditions and dyeing technology conditions, thereby overcoming the defects that all physicochemical indexes of products in the prior art, such as hexavalent chromlum content, free formaldehyde content, harmful aromatic amine content and other harmful substance contents as well as color fastness index, are not effectively solved. The technology of the invention pursues beautiful appearance of products and pays attention to inherent quality and human health increasingly; and especially, three hazards contents reach departmental standards, thus the invention becomes a processing technology of sheep shearing products which is green ecological, healthy and no harmful effect on customers.
Description
Technical field
The present invention relates to a kind of making of shearling industry sheep shorn velvet, especially relate to the complete processing of the compound shorn velvet hairsheep of tanning of a kind of chromium.
Background technology
At present, traditional straight chrome tanning or pure formaldehyde tanning method for making are continued to use in the tanning of domestic woolen velvet product always, though sense index can reach requirement of client substantially, can physical and chemical index be up to standardly ignored by people always, particularly sold inside the country product.In recent years, because American-European some textile products and the fur products of outlet is detected content of 6-valence Cr ions, free formaldehyde content, harmful aromatic amine content overproof, made traditional process for tanning can not satisfy export requirement.At home along with socioeconomic continuous development, the raising day by day of living standards of the people, people are increasing to the demand of fur product, specification of quality to product is also more and more higher, not only pursue the aesthetic feeling of outward appearance, simultaneously inherent quality and HUMAN HEALTH are also more and more paid attention to, particularly whether " three disasters " substances content is up to standard, becomes the focus that domestic and international human consumer pays close attention to.This just requires us must produce the green ecological product harmless to the consumer health.
China's patent application 200510043017.6 discloses a kind of " manufacture craft of chrome tanning grey blue loop cutting sheep skin ", its through choosing skin, fleece put, check, weigh, ease back retanning stuffing, degreasing, dyeing, water dumping, drying, moisture regain, stretching, extension, toggling, placement, the brush first hypo acid aldehyde, wetly scald hair, cropping, carding, do scald hair, secondary cropping, the brush second hypo acid aldehyde, secondary wet scald hair, three cropping, secondary do scald hair, check, smoked ammoniacal liquor, brush gloss-imparting agent, wet for three times boiling hot mao, four operations such as cropping make sheared sheep skin.Though it increases the Oranoleptic indicator of sheep shorn velvet broad wool product, objectionable impurities such as product physical and chemical index, particularly content of 6-valence Cr ions, free formaldehyde content, harmful aromatic amine content and colour fastness index are all effectively solved.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and the complete processing of a kind of high standard, the compound shorn velvet hairsheep of tanning of high-quality chromium is provided.
Technical problem to be solved by this invention realizes by following technological approaches:
The complete processing of the compound shorn velvet hairsheep of tanning of chromium of the present invention comprises and selects skin, and immersion widens mud, water dumping, cropping, scouring of wool, immersion, fleshing, cut edge, check, water dumping, two cropping, degreasing, immersion, slide oil, the pickling stuffing, pretan, skin is stretched in water dumping, composite tanning technology, leave standstill, extension dries in the air, pickling, bark degreasing, water dumping, nail-plate, classification, scald hair, cropping, check, classification gage, bundling warehouse-in, dry-cleaning, dye preceding degreasing, hair is scalded in dyeing, cropping, and processing steps such as check is characterized in that:
Described pickling stuffing processing condition are used equipment: paddle-tumble; Liquor ratio 1: 30; The hypodermis temperature is not mended temperature midway for 36 ℃; 48 hours time; Material: 1.4 milliliters/liter in formic acid, 1.2 milliliters/liter in sulfuric acid, salt 60 grams per liters, Blankit 0.1 grams per liter, fatting agent GLH 1 grams per liter, add fatting agent GLH 0.6 grams per liter after 30 minutes; PH2.4-2.7; Then going out skin left standstill 12 hours;
Described pretanning technology condition is used equipment: paddle-tumble; Liquor ratio 1: 30; 36 ℃ of hypodermis temperature; Material: the red D10 milliliter of sodium-chlor 60 grams per liters, 3 milliliters/liter in formic acid, bus/liter, add red D 6 grams per liters of bus day; Go out skin PH 2.9-3.0; Mend temperature once after 48 hours time, per 10 hours; Heat when going out skin to 42 ℃ with the iron trichloride skin that is up to the standards out; Skin is stretched in water dumping: fold is stretched;
Described composite tanning technology processing condition are used equipment: paddle-tumble; Prepare 100 liters of owses: with 25 kilograms of chromium powder AB, 21 kilograms of sodium formiates, 4 kilograms of chromium aluminum tanning agent AC, 501 auxiliary agents, 200 grams, 1.5 liters of fatting agent LP, PH 4.0, heat to 60 ℃, brush 2 times, brush and must not pollute fleece thoroughly, left standstill 24 hours, keep about 35 ℃ of temperature;
Described dyeing condition is used equipment: paddle-tumble; 120/3 tons of liquor ratios, temperature 62-68 ℃, add 0.5 milliliter/liter of DFL-II earlier, hypodermis dyed 20 minutes in advance, after add dyestuff: black BBM561.57 gram, yellow BBG 369.14 grams, blue F-KB 54.26 grams, red BBA 5.63 grams, mend 1000 milliliters in formic acid after 30 minutes, mend temperature to 65 ℃, mend 700 milliliters in formic acid again after 30 minutes, mend temperature to 68 ℃, draining adds the cold water rinsing after 30 minutes again, control water.
The present invention compared with prior art has the following advantages:
1, earlier rawhide is criticized by the old tender thin and thick area sorted group of the density dermatotome of hair, for the consistence of production control and quality creates conditions.
2, before the rawhide degreasing, ridge is drawn in the middle spine of dermatotome, fiber is drawn back, solve spine's thickness of slab problem with little fleshing machine.
3, adopt scouring of wool efficiently and remove the greasy grease-removing agent of dermatotome during degreasing, the disposable absolute oil fat that goes is for tanning quality and the Bai Jiedu that improves hair create conditions.
4, take the method for pickling stuffing, not only can make interfibrillar substance deposit that branch is cleared up but also can make hide fiber loose fully, solve part between the rib and the hip softening excessively in the softening insufficient problem of spine, thereby it is poor to dwindle the position.
5, take chromium composite tanning technology method after the first pretan, both can improve the fullness ratio of dermatotome, also can improve tensile strength and other every physical and chemical indexs, it is poor to dwindle the position, increases operation rate.
6, take to have uncommon power F series dyes, can improve glossiness, vividness and every colour fastness of fleece, can decompose harmful aromatic amine content and also reach ministerial standard than high color fastness.
7, the military products fur cap is taked earlier the fixedly method of poststaining, can solve the problem that formaldehyde content exceeds standard.
