Product Description

Leather Doctor® Aniline-21 is design for dye refinishing absorbent aniline leathers both like the smooth unfinished, glazed or pure aniline and the napped nubuck and suede. Other smooth aniline finishes types that has existing impairing dye penetrating topcoat has to be stripped with the help of Stripper-2.3 otherwise use Aniline-76 instead to coat over existing topcoat. Aniline-21 is a new generation odorless waterbased “staining” transparent aniline dyestuff that is more lively and brilliant than most liquid dyes. Provides a more superior light fastness and fades resistance than most standard liquid dyes.

General Sequence of Re-dyeing for Smooth Aniline Leathers:

A. Topcoat Stripping & Degreasing:

A1. All smooth leather surface finishing is not stainable and recommended to be stripped with Stripper-2.3 to allow even dye penetration into the leather crust with this “staining” Aniline-21 dyestuff. The presence of body grease and oil will resist staining and will result in blotchiness will be likewise degreases with Degreaser-2.2 follows with rinsing with Rinse-3.0. Acidifier-2.0 is used to control bleeding instead especially those body contact areas.

B. Other Stains Removal:

B1. Stains are removed accordingly, otherwise the darkest stain becomes the lightest color choice just to camouflage it, especially working with transparent dyestuff the beauty of the grain and the blemishes both equally will show through. Using a “translucent” dyestuff Antique-27 instead, will help better camouflaging it with reduced finesse.

C. Surface Wear & Abrasion:

C1. Where surface wear and abrasion is apparent by sight or by feel of hand and will require Adhesor-73 to smooth it. Aniline-76 transparent or Antique-27 translucent coating dyestuff becomes the obvious option.

D. Pre-inspection and Surface Pre-Conditioning with Hydrator-3.3

D1. Staining of dye is done after a check with Hydrator-3.3 for any surface tension. The leather may be completely saturated out to check for any surface blotchiness especially on heavily stained or used areas. Allowing any suspended below surface soiling to resurface and reverse transfer using a stretchable paper towel proves practical rather then still remaining on the leather surface. Until the leather crust or grain surface is without any surface tension that may manifest as blotchiness that Aniline-21 application begins. A final light mist spray inspection confirms that blotchiness or unevenness will not occur prior to the actual dye application.

E. Stain Dyeing with Aniline-21.

E1. Staining can be applied with lint-free paper towel, plush, foam or high quality varnishing brushes; without surface contact airbrushing produces the best result. Fast dry with air blower and the surface is inspected for evenness or correction until satisfaction.

E2. Surface evenness is further corrected or improves with Hydrator-3.3 using a lint-free towel and work over the surface to remove surface wick-up residue thus eliminating surface tension if any. By a wiping a Hydrator-3.3 saturated towel improves the overall appearance, allowing the dyestuff to further redistribute itself over the leather crust or grain.

E3. Inspect during each drying cycle when working with Hydrator-3.3 for evenness correction, improvement or control.

F. Fatliquoring with Fatliquor-5.0

F1. The surface is light mist with Hydrator-3.3 prior to Fatliquor-5.0 application. Fatliquor-5.0 is simply apply with using a 3” foam brush, spreading it and distributing for even saturation absorption to the entire surface at one time. As the water content evaporates more is applied at each drying cycle until the desired suppleness for softness and strength, replenishing up to 14% of the original tannery standard as so desired for its intent purpose, usage or appearance.

G. Pre-Conditioning Fatliquored Surface with Hydrator-3.3.

G1. Any surface tacky residue is removed with Hydrator-3.3, horsehair Brush-1 and towel extracted to a squeaky clean surface, let dry and ready for topcoating.

H. Topcoating with Aniline-21G, Aniline-21S, Aniline-21W and Aniline-21N.

H1. Aniline-21G (gloss) and Aniline-21S (satin) are inter-mixable developed for the standard gloss/satin aniline leathers. Satin may follow gloss for a luster adjustment. Application is done with varnishing brush or airbrushing. Minor surface roughness is corrected with 2000grit sanding in between dried application.

H2. Aniline-21W is developed for waxed aniline that produces a matte luster with a waxy feel to match original finishes.

H3. Aniline-21N is for pure-aniline lambskin or kidskin with the most natural feel that forms a discontinuous film for extra breathing comfort commonly for luxury garments and bags.

I. Non-Stick, Rub-Resistant Protection:

Use Protector-W+ for waxed aniline.

Use Protector-D+ for aniline wax pull-up.

Use Protector-B+ for gloss and satin finish leathers.

General Sequence of Re-dyeing for Nubuck, Nappa-Suede & Split-Suede:

1. Nubuck is leather that is buffed on the smooth side producing a super fine nap with suede as the reverse side, commonly used in upholstery and boots. Differentiating tools used are nylon Brush-2 and leather Eraser-4. Protector-S+ differentiates to produce a silky-feel to the finger writing naps.

2. Nappa-Suede is usually fine lambskin or kidskin with leather as the reverse side, commonly used as garments. Differentiating tools used are suede Brush-3 and suede Eraser-5, while the finer suede would be treated as nubuck. Protector-S+ differentiates to produce a silky-feel and a finger writing effect to the naps.

3. Split-Suede is the thickness of leather that has been split into layers with both sides as suede, finer to the grain-side and coarser to the flesh-side. Differentiating tools used are suede Brush-3 and suede Eraser-5. Protector-W+ differentiates to produce a waxy-feel and a finger writing effect to the naps.

A. Degreasing:

A1. Surfaces have to be prepared free of body contact grease, oil and sweat before dyestuff can stain the leather protein fibers. Besides all other surface contamination and stains has to be removed accordingly to reduce or avoid blotchiness. Basic degreasing system includes Degreaser-2.2 as the main product and Acidifier-2.0 in place of Rinse-3.0 to control bleeding especially on those body contact areas. Hydrator-3.3 helps to moves suspended soiling to the surface to be wet towel extracted and erased with appropriate eraser when crispy dry.

B. Other Stains Removal:

B1. Stains are removed accordingly, otherwise the darkest stain will be the lightest color intensity matched to just able to camouflage it, especially with transparent dyestuff the beauty of the grain and the blemishes both equally will show through. In the presence of unexpected impurities a hybrid dyestuff Nubuck-28 with better coverage is otherwise used instead.

C. Pre-inspection and Surface Pre-Conditioning with Hydrator-3.3

C1. Staining of dye is done after a check with Hydrator-3.3 for any surface tension. The leather may be completely saturated out to check for any surface blotchiness especially on heavily stained or used areas. Allowing any suspended below surface soiling to resurface and erased with appropriate eraser when crispy dry prior to dye application. Until the leather crust or grain surface is without any surface tension that may manifest as blotchiness that Aniline-21 application begins. A final light mist spray inspection confirms that blotchiness or unevenness will not occur prior to the actual dye application.

D. Stain Dyeing with Aniline-21.

D1. Staining is done with airbrushing with better control for distributing of dyestuff to produce the best result.

D2. Set air pressure (80 to 100psi).

D3. Adjust to cone shape spray.

D4. Increase atomization and decrease feed.

D5. Spray in circular motion with deep brushing without saturation.

D6. Repeat a section at a time and brush accordingly.

D7. Brush again when dry for a “finger writing effect”.

E. Post-inspection with Hydrator-3.3

E1. Any blotchiness correction is done with Hydrator-3.3 to saturate and redistribute the dyestuff for a more even appearance.

E2. Inspect during each drying cycle when working with Hydrator-3.3 for evenness correction, improvement or control.

F. Fatliquoring with Fatliquor-5.0

F1. The surface is light mist with Hydrator-3.3 prior to Fatliquor-5.0 application. Fatliquor-5.0 is applied by spraying, brushing and distributing for even saturation to the entire surface, without leaving out any areas, otherwise rings or marks will shows when dry.  As the water content evaporates more is applied at each drying cycle until the desired suppleness for softness and strength, replenishing up to 14% of the original tannery standard accordingly if so desired for its intent purpose, usage or appearance.

G. Pre-Conditioning for Dye Fixing with Hydrator-3.3.

G1. Any surface tacky residue from Fatliquor-5.0 is removed with Hydrator-3.3, brush and towel extracted to a squeaky clean surface, let dry and ready for dye fixing.

H. Dye Fixing with DyeFix-99  

DyeFix-99 is a waterbased dye fix for nubuck and suede to control and abate crocking. Crocking is greatly reduced or eliminated with good fixing. It improves wet rub fastness and reduces bleeding. It maintains its natural feel and nappy “finger writing effect”.

H1. Dye fixing is done with airbrushing with better control for distributing to produce the best result.

H2. Set air pressure (80 to 100psi).

H3. Adjust to cone shape spray.

H4. Increase atomization and decrease feed.

H5. Spray in circular motion with deep brushing without saturation.
