Abstract
The invention discloses a method for dyeing Tan sheep skin, which comprises the following steps: softening Tan sheep skin subjected to tanning and airing, and sequentially retanning and dyeing the Tan sheep skin. The dyeing process comprises primary dyeing and secondary dyeing in a rotating drum, wherein the primary dyeing is implemented by dyeing the Tan sheep skin in the rotating drum, in which the dye amount is 1/2-3/5 of the total amount, at 30-32 DEG C for 30-35 minutes; primary color fixation is carried out after the primary dyeing; after the primary color fixation, the rest of dye is added into the rotating drum to carry out secondary dyeing at 60-65 DEG C; and after the secondary dyeing, secondary color fixation is carried out. The dyeing and color fixation are sequentially carried out twice, thereby avoiding the phenomena of nonuniform dyeing and unclear pores due to thick coating, and ensuring the uniform dyeing of the Tan sheep skin. The treatment time of the whole dyeing technique is short.
Description
Technical field
The present invention relates to the fur manufacturing field, be specifically related to a kind of method for the sheep known for its fine thick wool leather dyeing.
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.Existing sheep known for its fine thick wool leather dyeing is generally finished in rotary drum, because therefore uneven the and serious phenomenon that fades of dyeing appears in the particularity of sheep known for its fine thick wool skin institutional framework and its fur easily.So method that is necessary to provide a kind of even dyeing, is used for the sheep known for its fine thick wool leather dyeing.
Summary of the invention
The purpose of this invention is to provide a kind of method for the sheep known for its fine thick wool leather dyeing, it can dye uniformly to the sheep known for its fine thick wool skin.
For achieving the above object, the present invention adopts following technical scheme: a kind of technology for the sheep known for its fine thick wool leather dyeing, comprise the processing that eases back of sheep known for its fine thick wool skin after the tanning airing handled, ease back and successively the sheep known for its fine thick wool skin is carried out that retanning is handled and dyeing is handled after handling, described dyeing is handled and being included in once dye in the rotary drum processing and secondary dyeing processing, described once dyeing is handled and to be referred to that it is 1/2～3/5 rotary drum of the total consumption of dyestuff that the sheep known for its fine thick wool skin is placed the dyestuff dosage, under 30～32 ℃ of conditions, dye system 30～35min, once dyeing is carried out fixation treatment one time after handling, again the dyestuff of surplus is added after fixation treatment and carry out secondary dyeing to the rotary drum and handle, the temperature that secondary dyeing is handled is 60～65 ℃, carries out the secondary fixation treatment again after secondary dyeing is handled.
By, successively twice pair of sheep known for its fine thick wool skin dyes and fixation treatment, and can avoid dyeing inequality and the unsharp phenomenon of thick coating pore guarantee the soft and soggy look of sheep known for its fine thick wool evenly and the processing time of whole dyeing weak point.Here said " once dyeing handle to refer to the sheep known for its fine thick wool skin is placed the dyestuff dosage be 1/2～3/5 rotary drum of the total consumption of dyestuff " refers to once dye and handles dyestuff dosage war one, two dyeing and handle 1/2～3/5 of used dyestuff summation.
Further scheme is:
Once dyeing is handled rotary drum and is dyed the dyestuff that contains 0.008～0.016g/L in the slurry, and the PH that dyes slurry is 3.5～4, dyes the acetic acid of the salt that also comprises 6.0～7.5g/ml in the slurry, 1～2ml/L quaternary ammonium salt aldehyde-free colour stabilizer, 0.02g/L.
A described fixation treatment is to add formic acid handle 10～15min under 35～38 ℃ of conditions dying in the slurry, the formic acid that contains 0.1～0.15ml/L in the slurry after stain slurry is dyed in the formic acid adding in the fixation treatment, described secondary fixation treatment is to continue to add formic acid handle 15～20min under 25～30 ℃ of conditions dying in the slurry, and the formic acid addition is 1.5～2.5 times of formic acid addition in fixation treatment in the secondary fixation treatment.
The temperature that retanning is handled is 30～35 ℃, and the time is 10～12h, and retanning is handled used retanning agent and formed by fatty alcohol-polyoxyethylene ether, acetic acid, network tanning agent mixed preparing.
Described once dyeing is also carried out ungrease treatment to the sheep known for its fine thick wool skin before handling, and the solution of ungrease treatment comprises the washing powder of 0.6～0.7mol/L fatty alcohol-polyoxyethylene ether and 5～7g/L, and the time of ungrease treatment is 20～25min, and temperature is 40～45 ℃.
Utilize segmentation that the sheep known for its fine thick wool skin is dyeed among the application, guarantee even dyeing, passed through the dyeing control of process condition simultaneously, the processing time that shortens the whole technology of dyeing can be arranged, improve the efficient of sheep known for its fine thick wool skin production and the quality of finished product sheep known for its fine thick wool skin.
