This document summarizes types of leather finishing processes. It discusses aniline finishing, which uses water-soluble dyes and is best for high quality leather with few blemishes. Semi-aniline finishing leaves the grain partially exposed with a thin protective layer. Pigmented finishing fully coats the leather with resin-based pigment to produce a uniform color and hide defects. Each type is suited to different applications - aniline is for soft items, semi-aniline for quality without maintenance, and pigmented is durable for everyday use and withstanding wear.

Seminar On Types Of Finishing In Leather Processing Department Of Leather Technology Harcourt Butler Technical University Guidance by: Mr. Abhishek Lal Sir Represented by RADHA Roll no. : 190109015
In the presentation, I will represent about types of finishing. Some topics are mentioned below… • First we will know ,what is the finishing. • Why we do finishing. • Types Of Finishing.
• What is the finishing. Finishing determines the appearance of the final surface of the leather and the surface of the leather and the surface properties. This includes colouring, waterproofing, wax dressings,but also mechanical processing stages such as ironing or embossing of the leather. For example:
• Why we do finishing. The purpose of finish is done in order to enhance certain qualities And characteristics for example protecting the leather look and feel By providing a texture which is waxier and smother. There are different types of finished leather…
• Types Of Finishing. The most common categories of leather finishes are… • Aniline • Semi-Aniline • Pigmented Aniline Finish : Only the highest quality Full Grain Leather can receive an Aniline Finish. This is because the grain remains exposed, And must have as few blemishes as possible. Aniline finishing involves using aniline dyes, which are water Soluble pigments.

Semi-Aniline Finish: Semi-Aniline leather leaves the grain exposed,But has a thin protective/corrective layer. Semi- Aniline finishes are applied to full grain leathers,with only a small amount of pigment being used . Semi-Aniline leather is a good fit for those who want high quality Leather without the frequent maintenance.

Pigmented Full Grain Leather: While this type of leather finish requires a heavier layer of material To mask details than Semi-Aniline finishes, it is still made of high- quality Full Grain Leather. A resin- based pigment is applied to hide defects, but it still maintain the look and feel of a quality product. This finish does not leave the pores visible, and hides the natural colour variations in the leather. The colour and surface are uniform And evenly coated with pigment, giving it great light fastness and stain Resistance.

• Which type of leather article are finished by which type of finishing process. Aniline Finish • Aniline finished leather are very soft,most pilable finishes, it is well suited for application. • This makes it great for clothing, shoes, and small accessories like belts and wallets.
Semi Aniline Finish: • Semi-Aniline leather is perfect for those who want high- quality leather without the maintenance. • It is suitable for most applications, including larger items like handbags and upholstery.
Pigmented Full Grain Leather: • This is one of the most common high quality leather finishes. It’s preferable for most people because it requires little maintenance and is more durable than the non pigmented leathers. • It is not as soft as the aniline leathers, but its stiffness and thicker topcoat allow it to hold up to rougher use without as much upkeep. • This sturdiness makes it ideal for everyday accessories and those that experience frequent year.
