Spray Plant is one of the advanced finishing technologies in Iran’s leather industry, designed to enhance the color, texture, and final appearance of leather. In this process, after preparation and passing through earlier stages, the leathers enter a fully automated system where multiple rotating spray guns evenly apply chemical substances such as dyes, resins, or finishing agents onto the leather surface.

In this method, the leathers are placed on a conveyor belt and continuously pass through the machine. The spray guns, mounted on a rotary mechanism, disperse the desired materials onto the leather surface with high precision. This ensures that the color coating or finishing layer is distributed completely evenly across the entire surface, without spots or irregularities. The result is enhanced color brightness, improved hand feel, and greater overall beauty of the product.

The main advantage of the spray plant is its precise control over the amount and uniformity of applied materials, resulting in vibrant, high-quality, and consistent colors—an essential requirement for luxury leather products such as export-quality handmade bags, premium shoes, and furniture upholstery. In addition to color application, this method can also apply protective coatings or special resins, which improve the durability and surface resistance of the leather against abrasion and moisture.

This technique is particularly effective for mass production, where speed, accuracy, and consistency of quality are crucial. The spray plant enables multiple pieces of leather to be processed simultaneously with the same level of quality, leading to reduced labor costs, increased efficiency, and rapid preparation of leather for final finishing or entry into the product manufacturing line.

Key characteristics of the spray plant process in Iran’s leather industry:

• Use of a fully automated system with rotary spray guns for even material application
• Enhanced uniformity of color, brightness, and leather surface softness
• Improved optical and tactile qualities (Optical & Hand Feel)
• Precise control over the amount of dye, resin, and finishing materials
• Suitable for mass production while maintaining consistent quality in every piece of leather
