Abstract
The invention discloses a clean production technology of Tibet lamb skin, which comprises the following steps of: performing tanning treatment on the Tibet lamb skin by a composite tanning agent; performing bleaching treatment on the Tibet lamb skin, and performing dyeing treatment on the bleached Tibet lamb skin. The dyeing treatment comprises the following steps of: performing drum primary dyeing in a drum of low-concentration dye and performing jet dyeing on the Tibet lamb skin after the drum primary dyeing; and performing tanning treatment on the Tibet lamb skin by the composite tanning agent, wherein the residual composite tanning agent of the tanning treatment can be recycled, and the tanning agent is firmly combined with collagenous fiber to facilitate the treatment on chrome tanning waste liquid. Meanwhile, due to the dyeing combining the drum primary dyeing and jet dyeing, the consumption of the dye can be reduced, the phenomena of non-uniform dyeing and thick coating and unclear pores can be avoided, and the cost of the dye and the treatment amount of sewage are reduced, thus clean production of the Tibet lamb skin is realized.
Description
Technical field
The present invention relates to the animal skin manufacture field, be specifically related to a kind of sheep known for its fine thick wool skin process for cleanly preparing.
Background technology
The sheep known for its fine thick wool skin is one of local and special products commodity of China's tradition outlet, and it is solid with dermatotome, and light warming ， Mao Hui smoothness is attractive in appearance, and undulations is crooked and have won fame both at home and abroad, and is that resource is produced in the advantageous herding in area, Ningxia.But have following two problem of environmental pollutions in the production of existing sheep known for its fine thick wool skin: one is during the tanning of sheep known for its fine thick wool skin is handled because the main chromic tanning that adopts, and the chroming waste liquor of its generation can't effectively be handled, contaminate environment; It two is to produce during dyeing is handled that the waste liquid that contains the higher concentration dyestuff in a large number also can't effectively be handled, contaminate environment, and the utilization ratio of dyestuff is low.
Summary of the invention
The purpose of this invention is to provide a kind of sheep known for its fine thick wool skin process for cleanly preparing, the waste liquid after its tanning processing and dyeing are handled is easy to handle, and reduces the utilization ratio height of environmental pollution and raising dyestuff.
For achieving the above object, the present invention adopts following technical scheme: a kind of sheep known for its fine thick wool skin process for cleanly preparing, it comprises following operation steps: the sheep known for its fine thick wool skin is carried out tannin handle, the sheep known for its fine thick wool skin bleached handle and to the processing of dyeing of the sheep known for its fine thick wool skin after the bleaching, described dyeing handle carry out in the rotary drum that is included in the lower concentration dyestuff that rotary drum just dyes and rotary drum just dyed after the sheep known for its fine thick wool skin carry out spray-painting, tannin is handled used composite tanning agent and is made of following component: the aluminum chloride of 2～5 weight parts, the tetrahydroxy sulfuric acid squama of 5～8 weight parts, 10～20 parts by weight of acrylic resin retaning agents, the ethylenediamine tetraacetic methene ammonium phosphate of the fatty alcohol-polyoxyethylene ether of 0.5～1 weight part and 0.5～1 weight part; The used spray-painting dyestuff of spray-painting is made of following component: the methylene radical dimethyl sodium dinaphthalenesulfonate of the metallized dye of 5～10 weight parts, 0.1～0.5 weight part, the fatty alcohol-polyoxyethylene ether of 0.2～1.0 weight part and the water of 150～200 weight parts.
The composite tanning agent that constitutes by, said components and the collocation of aluminium salt carries out tanning to the sheep known for its fine thick wool skin to be handled, and the remaining composite tanning agent that tanning is handled is recyclable to be utilized again, and tanning agent is combined firmly with collegen filament, is convenient to the processing of chroming waste liquor.Just dye to combine with spray-painting by rotary drum simultaneously and dye, can reduce the consumption of dyestuff like this, can avoid again dyeing inequality and the unsharp phenomenon of thick coating pore reduce the cost of dyestuff and the treatment capacity of sewage, thereby realize the cleaner production of sheep known for its fine thick wool skin.Here just to dye the consumption that refers to dyestuff in the rotary drum be about 1/5 of traditional drum dyeing dye dosage to the rotary drum of said low dye concentration, and the dyestuff when rotary drum just dyes in the rotary drum can be exhausted by the sheep known for its fine thick wool skin substantially.
Further scheme is:
Acrylic resin retanning agent is by the acrylic copolymer of vinylformic acid, Hydroxyethyl acrylate and acrylic acid amides copolyreaction generation and the polyoxy Fatty Alcohol(C12-C14 and C12-C18) is compound prepares, and the weight ratio of vinylformic acid, Hydroxyethyl acrylate and acrylic acid amides is: 1～5:2～3:1～4; The weight ratio of acrylic copolymer and polyoxy Fatty Alcohol(C12-C14 and C12-C18) is 50:1～1.5.
Obtain after the chromium complexing agent that described metallized dye is generated by potassium bichromate and glucose acidifying and the azo raw material hybrid reaction.
The temperature that tanning is handled is 25～30 ℃, and the time is 3～4h, the PH=6.5 of tanning treatment solution～7, and composite tanning agent adds by the amount of 10～20g/L in the tanning treatment solution.
The PH that used rinsing liquid is handled in bleaching is 7～7.5, and rinsing liquid comprises the sodium-chlor of 20～25g/L, the trisodium phosphate of 3～4g/L, the hydrogen peroxide of 10～15ml/L, the ammoniacal liquor of 1～4ml/L, and the time that bleaching is handled is 0.5～1h.
The temperature that described rotary drum just dyes is 45～50 ℃, time 30～40min, and the PH that dyes slurry is 3.5～4, dyes salt, 1～2ml/L quaternary ammonium salt aldehyde-free colour stabilizer that slurry comprises 0.002～0.004g/l dyestuff, 6.0～7.5g/ml in the rotary drum.
The spray-painting amount of spray-painting is 380～400ml/m
2Also rotary drum just being dyed the back beach sheepskin before the spray-painting carries out fixation treatment, soaps and dries processing, described fixation treatment is to point to the interior formic acid that adds of rotary drum to carry out fixation, the content of formic acid dye liquor in rotary drum is 0.15～0.2mol/L, the temperature that fixation treatment is handled is 20～30 ℃, time 30～40min.
Utilize a little aluminum chloride and tetrahydroxy sulfuric acid squama, acrylic resin retanning agent, fatty alcohol-polyoxyethylene ether to constitute the composite tanning agent that the sheep known for its fine thick wool skin is carried out tanning jointly among the application, guarantee that the sheep known for its fine thick wool skin fur light after tanning is handled is pure white, plentiful, the frivolous softness of slab, performance such as anti-oxidant, reduction, acid and alkali-resistance, anticorrosion, shrinkage temperature, dyeing is good.The use of composite tanning agent can avoid the simple effectively processing of the existing waste liquid of chromic tanning, aluminum tannage, contaminate environment, tanning agent to be combined with collegen filament firmly, produces problems such as hair.Just dye simultaneously with spray-painting two steps operation the sheep known for its fine thick wool skin is dyeed, guarantee even dyeing, by the spraying dyestuff that said components constitutes, can guarantee the Color of sheep known for its fine thick wool skin.Just dye owing to the dyestuff that uses lower concentration carries out rotary drum among the application simultaneously, after the process fixation treatment, the ground dyestuff can be exhausted by the sheep known for its fine thick wool skin basically fully in the rotary drum like this, is convenient to the processing of sewage in the production of sheep known for its fine thick wool skin, realizes the cleaner production of sheep known for its fine thick wool skin.
