Don't be afraid to wash your silk!

Silk delivers shine and drape, warmth, and strength all in one beautiful package.

It's a very special fiber that's meant to be worked with, and especially worn! I have several items knitted from silk yarn, and I've always been wary of laundering it.

The January/February 2014 issue of Handwoven focuses on silk, and there's a fantastic article about washing your silk garments. Here's an excerpt for you:


Washing Silk

Although you may be accustomed to buying silk clothing labeled “Dry Clean Only,” you can wash silk. After all, silk has been in use for over five thousand years and the modern-day dry-cleaning process didn’t begin until the mid-eighteenth century. Washing silk requires a bit of care but is not difficult.


One reason silk manufacturers recommend dry cleaning is that silk can lose its characteristic sheen with incorrect washing. Silk fibers are sensitive to abrasion, which can occur when the silk rubs against itself or other, rougher fabrics or against a metal washing machine drum. An abraded silk fiber will appear whitish or as though sprinkled with powdered sugar because the outer layer of the silk, which provides the light reflectivity, has been roughed up.

When you wash silk, use a lot of lukewarm water (70°–90°F) in proportion to the silk. If the silk is floating freely in the water, it will be less likely to rub against itself or other surfaces, minimizing damage due to abrasion.

Washing can also affect the drape of silk. How many of us have washed a luxurious silk blouse or scarf only to be horrified by the stiff fabric that emerged from the wash? Well, fear not. Your silk fabric is not ruined. Here’s an easy fix that I learned from Treenway Silks’ founder, Karen Selk.

Step 1: When the silk is slightly damp, move the piece around in your hands for a few minutes. This will bring up the sheen and minimize the stiffness when the silk is completely dry.

Step 2: Take your dry silk item and whack it against the back of a chair a couple of times. Feel how soft your silk is again? It’s that easy!

Here’s what just happened. Even on degummed silk, there is a bit of residual sericin (water-soluble proteins that glue the cocoon together), and these proteins stiffen when the wet silk dries. Whacking softens the sericin, restoring the luster and hand of the silk. With use and washing, the residual sericin will come out of the silk over time and less finishing will be needed.

So fear not, silk knitters, your fabric is tougher than it looks. Much tougher—I want to wash something silk right now just so I can give it a whack!

Weaving and knitting are such kindred spirits; I encourage you to treat yourself to a subscription to Handwoven magazine. It's a wonderful publication that I know you'll enjoy.
