Denim Garment Finishing: Process Overview

Welcome to the Process Overview course where you will learn about “Basic Process” and “Premium Finish Process”.

Basic Finish Process

The process begins when loomstate jeans — that is, jeans that have not yet been through the finishing process — are brought to a rotary or belly washing machine and loaded. They may be directly stonewashed or may be desized prior to stoning. Enzymes may also be used either before or with stonewashing. Once the process is complete, the jeans are unloaded and transported to an area for de-stoning. The jeans are then placed in another machine to be washed and softened. After drying, the jeans are pressed, inspected, and packaged for shipment.

Premium Finish Process

Premium jeans go through many of the same processes as casual jeans, with some additions, which typically involve techniques that age the jeans or give them special effects. Effects such as resin whiskers, accent abrasion, and color discharge can be combined to achieve the final premium effect. In whiskering, the goal is to give the jeans sharp, distinct whiskers on the lap area and behind the knees.

 

After whiskering, the jeans are cured, followed by dry abrasion, which can include premium details, such as abrading the cuffs with a grinding wheel and using a Dremel tool to abrade other areas, such as the pockets and belt loops. Hand sanding is then done on whiskers, creases, and other targeted areas. Wet finishing may include treatments with potassium permanganate or enzymes. The final processing steps include drying, pressing, inspection, and packaging.
