Yes, raw denim is designed to shrink after its first wash, especially if it’s unsanforized. This shrinkage is a natural part of the break-in process, allowing the jeans to mold to your body for a personalized fit. The amount of shrinkage can vary depending on the denim’s weave and the washing method used.
Understanding Raw Denim Shrinkage: What to Expect
Raw denim, also known as dry denim, is unwashed and untreated. This means it retains all its original indigo dye and sizing. When you wash raw denim for the first time, the fibers will contract, leading to shrinkage. This is a highly anticipated step for many raw denim enthusiasts, as it contributes to the unique patina and fit that develops over time.
Why Does Raw Denim Shrink?
The primary reason for shrinkage is the relaxation of the cotton fibers. During the manufacturing process, denim is often stretched and treated with sizing agents. Washing, particularly with hot water, causes these fibers to revert to their original state. This process is more pronounced in unsanforized denim, which has not undergone a pre-shrinking process.
Sanforized vs. Unsanforized Denim: A Key Difference
Understanding the difference between sanforized and unsanforized denim is crucial for predicting shrinkage.
| Feature | Sanforized Denim | Unsanforized Denim |
|---|---|---|
| Pre-Shrunk | Yes, mechanically pre-shrunk during production. | No, retains its full original size. |
| Initial Fit | Closer to its final intended fit. | Will be larger, anticipating shrinkage. |
| Shrinkage | Minimal shrinkage (typically 1-3%). | Significant shrinkage (can be 5-10% or more). |
| Break-in | Shorter break-in period. | Longer, more involved break-in process. |
| Feel | Softer, more comfortable from the start. | Stiffer, requires more wear to soften. |
Sanforized denim has been treated to minimize shrinkage. While some minor shrinkage might still occur, it’s far less dramatic than with unsanforized varieties. Unsanforized denim, on the other hand, is the purist’s choice, offering the most dramatic transformation and a truly custom fit after washing.
How to Wash Raw Denim to Control Shrinkage
Washing raw denim can be a daunting prospect, but with the right approach, you can manage shrinkage effectively. The goal is to achieve a good fit without over-shrinking your jeans.
The Cold Wash Method for Minimal Shrinkage
For those who want to minimize shrinkage, a cold water wash is your best bet. This gentler approach allows the fibers to relax slightly without aggressive contraction.
- Turn jeans inside out: This protects the indigo dye from excessive abrasion.
- Use a small amount of mild detergent: Avoid harsh chemicals or bleach.
- Wash on a delicate cycle: A gentle agitation is sufficient.
- Avoid the dryer: Always air dry your raw denim.
Hot Water Wash for Maximum Shrinkage
If you’re working with unsanforized denim and want to achieve a tighter fit quickly, a hot water wash can be effective. Be aware that this will result in the most significant shrinkage.
- Fill a bathtub with cold water first: Then add hot water to achieve your desired temperature.
- Submerge jeans completely: Ensure even saturation.
- Agitate gently: Move the jeans around in the water.
- Soak for 30-60 minutes: This allows the fibers to loosen and shrink.
- Rinse thoroughly: Use cold water to remove all soap residue.
- Air dry: Hang them to dry, preferably in a way that allows for maximum stretch.
The Importance of Air Drying
Regardless of the washing method, always air dry your raw denim. The heat from a machine dryer can cause excessive and uneven shrinkage, potentially damaging the fabric and leading to an undesirable fit. Hanging your jeans to dry can also help you guide the shrinkage in a desired direction.
How Much Will My Raw Denim Shrink?
The amount of shrinkage you can expect varies greatly. Several factors influence this:
- Denim Weight: Heavier denim (e.g., 16oz and above) tends to shrink more than lighter weights.
- Weave Type: Tighter weaves may shrink less than looser weaves.
- Cotton Type: Different cottons have varying fiber properties.
- Washing Temperature: As discussed, hotter water leads to more shrinkage.
- Detergent Used: Some detergents can affect fiber behavior.
As a general guideline, unsanforized denim can shrink up to 10% in length and 2-4% in width. Sanforized denim will shrink much less, often only 1-3% in length. It’s always wise to err on the side of caution and consider buying raw denim that is slightly larger than your usual size, especially if you plan on washing them soon.
Practical Tips for Sizing Raw Denim
When purchasing raw denim, consider these sizing strategies:
- Try them on: If possible, try on the jeans before buying.
- Account for shrinkage: If buying unsanforized, aim for a fit that is slightly loose initially.
- Consult size charts: Reputable brands provide detailed size charts that often include pre- and post-wash measurements.
- Read reviews: Customer reviews can offer valuable insights into actual shrinkage experiences.
People Also Ask
### How long should I wait before washing my raw denim?
Many enthusiasts recommend waiting at least six months before the first wash. This allows the denim to develop significant fades and a personalized shape. However, some prefer to wash sooner to control shrinkage or achieve a cleaner look. The decision is largely personal preference.
### Will washing raw denim in the ocean shrink them?
Washing raw denim in the ocean can contribute to fading and a unique texture, but it doesn’t typically cause significant shrinkage. The saltwater is less aggressive than hot water. For substantial shrinkage, a hot water soak or wash is more effective.
### Can I shrink raw denim faster?
Yes, you can speed up the shrinking process by using hot water for the initial wash and then tumble drying on high heat. However, this method carries a higher risk of over-shrinking and can potentially damage the denim’s integrity. It’s generally not recommended for preserving the longevity and best appearance of your jeans.
### What is the best way to wash raw denim to preserve color?
To preserve the indigo color, always wash your raw denim inside out in cold water. Use a minimal amount of gentle detergent and avoid harsh chemicals. Air drying instead of machine drying also significantly helps in maintaining the deep blue hue and preventing uneven
