Description

The method of primary dyeing production mercerising leather

Technical field

The invention belongs to leatherwork technical fields, and in particular to a method of primary dyeing production mercerising leather.

Background technique

Mercerising skin is because its outstanding texture and elegant and graceful appearance are increasingly liked by consumer, and with ox-hide etc. Mercerising corium its feel that natural cladding is process is more preferably.Existing mercerising skin is made by cow split leather mostly and is obtained, and one As need to assign cladding preferable coloring effect by secondary dyeing.In addition, there is also water-fast for existing mercerising skin finished product Wash the not high deficiency easily to fade of color fastness.

Therefore it is good coloring effect can be made by once dyeing how to improve to the manufacture craft of mercerising skin And the mercerising skin that washing color fastness is high, just seem particularly important.

Summary of the invention

The purpose of the present invention is to solve the deficiencies in the prior art, and provide a kind of once dye and make mercerising leather Method, the colouring of mercerising leather made from this method is uniform, soft, while also having preferable washing color fastness.

The present invention adopts the following technical scheme:

The method of primary dyeing production mercerising leather, including the processing of water field and the processing of dry field, the water field processing includes such as Lower step: by the wet blue of skin body exquisiteness successively through rewetting → retanning → mention alkali → neutralization → pre- stuffing → dyeing → main stuffing → It is fixed, obtain water field cladding；The dry field processing includes the following steps: gained water field cladding successively through drying → mill skin → primary It falls drum → primary spraying drying → secondary drum that falls → secondary spraying drying → and falls drum three times to get the Kosé smooth bark material；

The rewetting specifically: wet blue is taken, weighs, places it in rotary drum, according to the mass percent meter of wet blue, Successively by the water of 100%-200%, degreasing agent OC, 0.6%-0.8% of 0.35%-0.45% ecchymose removing agent TJ-A9811, The rewetting agent W of 0.4%-0.6% is added in rotary drum, runs 55~65min, adds the macerating enzyme CL of 0.9%-1.1%, runs 55~65min sequentially adds the oxalic acid of 0.55%-0.65%, the formic acid of 0.25%-0.35%, runs 55~65min, adds The water for entering 0.9%-1.1% carries out wash water, and drain sequentially adds the water of 75%-85%, the formic acid fortune of 0.25%-0.35% 25~35min of row；

The retanning specifically: according to the mass percent meter of the wet blue, continue the aldehyde tannage of 0.15%-0.25% Agent GX is added in rotary drum, runs 25-35min, sequentially adds the acrylate copolymer tannin of 1%-2%, the chromium powder of 2%-4% (Turkey) AB runs 110-130min, the water of 45%-55% is added.

Further, the temperature for the water being added in the rewetting step is 45~55 DEG C,

Further, described to mention alkali specifically: according to the mass percent meter of the wet blue, to continue 1%- 1.5% sodium formate is added in rotary drum, runs 25-35min, adds the sodium bicarbonate of 0.45%-0.55%, runs 25- 35min, the water that 0.8%-1.2% is added carry out wash water, and drain adds the water of 110%-130%.

Further, the neutralization specifically: according to the mass percent meter of the wet blue, continue 1.5%- 2.5% sodium formate, the neutralization tannin GA of 2.5%-3.5% are added in rotary drum, run 35-45min, sequentially add 0.8%- 1.2% sodium bicarbonate, the dodium thiosulfate of 0.6%-1.0%, 0.5%-0.9% sodium sulfite, run 85-95min, be added The acrylate resin tanning agent of 0.8%-1.2% runs 55-65min, and the water that 0.8%-1.2% is added carries out wash water, drain；

The pre- stuffing specifically: according to the mass percent meter of the wet blue, continue the synthesis of 1.5%-2.5% The sulfited oil EG 60 of oily YY707,0.8%-1.2% are added in rotary drum, run 25-35min.

Further, the dyeing specifically: according to the mass percent meter of the wet blue, continue 1.5%- The compound retanning agent of 2.5% novel syntannin UR, 0.5%-1.5%, 1.5%-2.5% dispersion tannin SLF, The ammonium hydroxide of 0.8%-1.2%, the dyestuff of 2.5%-3.5% are added in rotary drum, run 55-65min, look into.

Further, the main stuffing specifically: according to the mass percent meter of the wet blue, continue 3.5%- The sulfited oil EG of sulfiting synthetic oil AC, 2.5%-3.5% of 4.5% synthetic oil YY707,3.5%-4.5% 60, the mould inhibitor DA of sulfated oil AK, 0.1%-0.3% of 0.5%-0.9% are added in rotary drum, 55-65min are run, to color；

The fixation specifically: according to the mass percent meter of the wet blue, continue to turn the formic acid addition of 3%-4% In drum, 25-30min is run, the water that 0.9%-1.1% is added carries out wash water, and drain is roused out, obtains water field cladding.

Further, temperature when described dry is 70-90 DEG C, time 12-24h；It is described when once falling bulging Temperature is 30-60 DEG C, time 2-3h, and secondary temperature when falling bulging is 40-70 DEG C, time 4-6h, described to fall three times Temperature when drum is 50-70 DEG C, time 30-60min.

Further, the primary spraying drying specifically: mix Kosé gloss oil rouge and water according to mass ratio 1:8-12 It closes, a spray paint is made, by a spray paint even application on cladding surface, the dry 16-24h at 50-60 DEG C, described one The quantity for spray of secondary spraying is that every 2000kg cladding sprays spray paint of 60-100kg.

Further, the secondary spraying drying specifically: mix hand feeling agent and water according to mass ratio 1:6-12, system Secondary spray paint is obtained, by secondary spray paint even application in cladding surface, dry 1-2min, the secondary spray at 80-90 DEG C The quantity for spray of painting is 30-40 grams/m of skin base.

Compared with prior art, the present invention has the advantages that:

First: the present invention carries out processing to cladding by water field process and dry field process, in Shui Changchu In reason, alkali → neutralization → pre- stuffing → dyeing → main stuffing → fixation is mainly mentioned by rewetting → retanning →, cladding is carried out effectively Processing, wherein rewetting, retanning, proposing alkali, neutralization and pre- stuffing processing, to ensure that cladding dyestuff in dyeing is easier to infiltration cladding fine Dimension, and ensure that the uniformity of dyeing；It is handled in combination with main stuffing, it is more soft and smooth plentiful to make cladding feel, and pass through regular worker The dyestuff that ordered pair infiltrates into cladding is fixed, and so that cladding is had preferable coloring effect and stronger color fastness, reduces The migration of cladding color；In the process of dry field, the main drying → mill skin that passes through → once falling drum →, which once sprays, to be dried → The secondary drum that falls → secondary spraying drying → falls drum three times and post-processes to cladding, falls bulging setting three times, can make cladding hand Sense more preferably, primary spraying and it is secondary spray the handling property for not only further ensuring cladding, keep cladding more soft, also to dyeing after Cladding carried out color protection, further enhance the color fastness of cladding.

In addition, in the manufacturing method of the present invention, first using ecchymose removing agent TJ-A9811, rewetting agent W, degreasing in the rewetting stage Agent OC handles cladding, reuses after macerating enzyme CL handles cladding, oxalic acid is added by a small amount of by several times, makes rewetting Environment is maintained at pH5-5.5 or so, can effectively remove the miscellaneous spot on cladding surface, avoids the dyeing of miscellaneous spot bring is uneven from lacking It falls into；

Second: production method of the invention does not need to carry out two dyeing techniques, so that it may so that mercerising skin just has preferable dyeing The color fastness of effect；

Third, production method mild condition of the invention are suitable for popularization and application convenient for operation.
