Why are there so many products just for redyeing?
These 11 individual products are grouped up into 4 sequences of process systems 1* Preparation Cleaning, 2* Hydrating Reconditioning, 3* Redyeing, and 4* Protection.
1* Preparation Cleaning is performed with 5 product systems recommended Stripper 2.3, Degreaser 2.2, Acidifier 2.0, Clean 3.8, and Rinse 3.0. Stripper 2.3 is to remove deteriorating topcoats. Degreaser 2.2 is highly recommended to those body contact areas and Acidifier 2.0 as the system rinse. Clean 3.8 and Rinse 3.0 systems are for those light-soiling non-body contact areas.
2* Hydrating Reconditioning is performed with 2 product system Hydrator 3.3 and Fatliquor 5.0. Hydrator 3.3 relax and plump the dry and stiff leather structure as preconditioning for Fatliquor 5.0 easier penetration and distribution deep into the leather structure for leather softness and strength when dry.
3* Redyeing involves 3 product system that completes the process, that is Aniline 21, Aniline 76, and Aniline Top 76G. Aniline 21 is a staining dye and when the surface has uneven absorption, a coating dye with Aniline 76 covers up the uneven appearances with greater satisfaction. Then the dyes are sealed with Aniline Top 76G to a glossy luster.
4* Protection is simply applying a non-stick rub-resistant buttery feel protector for seating comfort and prolonging the wear of the leather from friction rubs with an option of a classic leather scent that charms.
How can I salvage and repair leather from cracks and abrasion?
Leather Repair Kit A8.r comes with 4 products essential for the 1*Bonding, 2*Tightening, and 3*Smoothening repair system.
1* Bonding Repairs with Bond 3D is a water-based resin bond that becomes part of leather and often works with Patch 4S for leather repairs.
2* Tightening Repairs with Impregnator 26 penetrates the weakened, overstretched leather and tightens it becoming part of the leather.
3* Smoothening Repairs with Adhesor 73 smooths the rough abraded surface and becomes part of the leather surface grain for further coat dyeing.
What is Aniline leather?
Aniline leather is leather that has dyed through to the reverse suede side with transparent dyestuff. The surface is further dye-coated to even out its appearance and sealed with a urethane clear gloss topcoat to show the beauty of the grain surface. Micro-crazing develops sooner, making the leather more comfortable in transpiration and a bit more absorbent.
What are Body Oil, Grease, and Sweat Damages?
How to know it is Aniline leather?
Check the reverse suede side, it should be the same shade as the original unexposed areas.
Can I use dishwashing soap or liquid on Aniline leather?
Not recommended! Most dishwashing soap or liquid has an alkaline pH value from 8 to 10. Leather has an acidic pH value from 3 to 5. Leather is an amphoteric protein material, so any liquid above the pH value of 7 will denature the leather by shifting the leather protein fiber ionic negative (-ve). Behaving like a magnet 'like poles repel' the ionic attraction weakens and all the negative (-ve) leather constituents like the tanning agent, dyestuff, and fatliquor migrate and leach out. These side effects manifest as dye bleeding from dyestuff, tackiness from tanning agents, cloudy residue, and dry stiffness from the fugitive fatliquor, the leather returns back to rawhide.
Can I use a high-pressure steamer to clean Aniline leather?
Not recommended! Heat will shrink the leather. About 14% of the original leather is composed of fatliquor (fat and oil) to keep its softness and strength. The percentage diminishes since fat and oil are VOC (volatile organic compounds) further heat will accelerate the drying process making the leather dry, stiff, and crack when stressed.
Can I keep the original light color?
To keep the original color will depend on whether it is painted with a pigment color like Micro 54 or varnished with a combination of Aniline 21 and 76. Pigment color is an opaque color that covers and blocks any color below, but it is no longer perceived as a high-end product. Aniline is a transparent dyestuff that magnifies both the blemishes and the beauty of the grain to show through. Natural scars and blemishes are often times left alone as 'Salvage' leather. The color intensity of aniline dye is built up by layers and can be controlled accordingly to satisfaction just to camouflage any darkening marks.
Sequence of Process Overview
Most severely penetrated, prolonged, and neglected stains show a darkening effect with a sticky feel have its topcoat and dyestuff most probably deteriorated by the fermenting sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from the breaking of the hydrogen bonds with the tanning agent. When the sign of color is transferred to a white towel, it indicates that the dyestuff has also broken bonds with the protein fiber. When leather is stiff or shows signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH mainly caused by sweat to alkalinity affects the pH balance. To revert from denaturing into rawhide prior to topcoat refinishing, contaminated alkaline soiling is removed with Degreaser 2.2. Degreaser 2.2 is a water-based pH 2.2 multifunctional degreaser that emulsifies greasy contamination besides controlling dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff, and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse and pH balanced with Acidifier 2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of a healthy leather. Hydrator 3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil are replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Custom dyeing commences prior to topcoat refinishing. Protector B'plus imparts a non-stick rub-resistant protection with a buttery feel that shields against sticky soiling and reduces friction noises, with a classic leather scent that charms.
