A Basic Guide To Washing Denim Jeans
Jeans are a staple of almost every one’s wardrobe. Basic blue and black is every one’s favorite, but you can now find several different colors, washes, and designs. Manufacturers use special techniques to create these textures or washes and they impart a trendy appearance to the finished garment. According to customer demands, manufacturers can also create custom or personalized washes. If you are interested in learning more, we’ve created a short guide that should prove informative.
Step No 1 – Pre-Treatments
Before the denim fabric can be treated or stitched, it is washed and cleaned to remove dirt and impurities. At the same time, the washing process removes any written notations and starch treatments done on the fabric. Washing will also ready-shrink the fabric and prevent changes later on when the garment is ready for final washes.
Step No 2 — Enzyme Wash
Four enzyme varieties are used to treat the fabric before it is processed into jeans. These enzymes are designed to remove lingering fabric tags, smooth out the rough denim fabric, and create textures in the denim fabric. These textured fabrics can then be stitched into jeans that have the pattern all over the jeans.
Step No 3 — Clean Up
Once the material has acquired the overall pattern and design, it is cleaned up or washed again to remove the lingering enzymes. Materials like non-ionic detergents, hot water and detergent washes, and hydrogen peroxide to seal in the finish and to remove excess enzyme.
Step no 4 — Selection
Once the material is ready, manufacturers then decided the type of finish or wash that the jeans require. At this stage, the material is stitched into jeans to created characteristic wear patterns or the entire fabric is treated again to create the custom wash. A few of the most common patterns include the following:
• Bleaching or acid washing — Different bleaching agents like hydrogen peroxide, potassium permanganate, calcium hypochlorite, etc. can all be used to create unique textures and washes on the jeans.
• Stone wash — Stone washing is also a very common method of treating denim. In this method, pumice stones are whirled with denim jeans to create the worn abraded look on the front and back of the jeans.
• Micro sanding — This is usually done by sandblasting, machine sanding or hand sanding. The purely mechanical process wears away the dye on the front of the jeans. The lighter patches are around the knees with characteristic wrinkle patterns around the thigh area.
• Other techniques like rinse washes, over dyes, cellulose wash, salt water denim washes, ozone fading, sun washing, etc are also available.
Some manufacturers skip the wash process and go ahead to single color dark staining procedures to create the characteristic dark black or indigo colored jeans. As you can see, the entire process is quite complicated but it does create a unique, comfortable and trendy garment.
