The leather finishes has first need to be identified before we known which product system that will match.

Picture #2 looks like originally it is “Nubuck” with the grain been buffed to create a nappy finish.

The rest of the pictures show a gloss typical of “Aniline”, but when Nubuck through used and with un-match products may smooth out the nappy nubuck.

Which way to go Nubuck or Aniline?

Nubuck is top-grain cattle leather that has been buffed on the grain side, or outside, to create a velvet like texture or nap. It has the characteristic of a slight nap, with the softest “hand” or tactile feel. Although nubuck is aniline dyed through it is commonly finish with a surface dye sometimes incorporating micro-pigment to cover up some natural blemishes. It looks similar to suede, but the difference is that suede is created from the flesh side of leather, whereas nubuck is created from the grain side of leather. As both nubuck and suede are napped leather, it is often incorrectly identified as suede. Leather is both hydrophilic and oleophilic, nubuck especially with its open nap absorbs both water and oil more readily, than any other smooth leather. It is generally more expensive than suede; fashion types include embossed, oil and wax pull-up effect. Fatliquor plays an important role when comes to maintenance to both reduce ingress of waterbased and grease stain; plumps the leather with fullness, reduces creases, and wrinkles. Leather protein-fiber component is amphoteric therefore, a leather-safe (pH 3 - 5) care product system is highly recommended to keep them clean while maintaining their chemistry integrity

Aniline leather is soft and natural. They are usually first treated with transparent dyestuff to make the grain and natural characteristics more visible. Modern tannery dyeing is done in a rotating drum in a continuous process follows with fatliquoring. When dried thereafter, the leather goes through another selection or grading to decide the best treatment to bring out their potential softness and natural look. Thus, further sub-divide into various varieties. However, the bulk of aniline leathers after dyeing may reveal uneven grain dye absorbency and too many faults, so that the variation in color over the entire grain surface is too great for many leather fabrications.

Questions!

Do you have a sample or identification label to determine if it was nubuck or aniline before I recommend a matching system?
