Yes, salt water can ruin silk. Prolonged exposure to saltwater can damage silk fibers, making them weak and brittle. This is because the salt in the water reacts with the silk protein, causing it to break down.
Here are some reasons why salt water can damage silk:
- Weakening of fibers: Saltwater can weaken individual silk strands, making them more prone to breakage, especially when handled roughly. This is due to the sericin, a protein that supports the silk weave structure, being water-soluble.
- Permanent water spots: Saltwater can leave permanent water spots on silk, especially if the water is allowed to dry on the fabric.
- Bleach-like effect: Chlorinated pool water can bleach silk, and saltwater can have a similar effect, although less severe.
Therefore, it's best to avoid wearing silk in saltwater environments or washing it with salty water.
