The first thing you need to know about how to dry silk pillowcases is that you should never put them in the dryer. The high heat of a dryer — even on a low setting — will destroy the silk's fiber.
Don't put silk items in the dryer. Heat can damage delicate silk fibers. If the dryer is absolutely necessary to use only 'air' setting for 15 minutes or less with NO fabric sheets or dryer balls. Remove sheets before completely dry.
Avoid wooden drying racks which can leech dyes or stains into silk. Your silk should dry in about 45 minutes depending on temperature and conditions. DO iron sparingly, only on the coolest setting with sheets and turn your pillowcases inside out.
Exposing your garment to long bursts of sunlight can cause the colors to fade or even damage your silk fabrics. Do not tumble dry. Silk is very delicate and the high temperatures of the tumble dryer can shrink or damage your silks. Use a detergent for delicates.
Using too much detergent can leave residue on the fibers, making them feel rough and stiff. This is because detergents can strip the natural oils from the silk, which help to keep the fibers soft and smooth. To avoid this, use a gentle detergent and follow the recommended amount for the size of your load.
Never wring out your silk items or toss them in the dryer, says Whitehurst. To remove excess water, place the wet garment on a white cotton towel. Fold the towel over and gently blot. Then, using a padded hanger, hang the blouse or dress over the bathtub to drip dry.
Silk is a very delicate material and you should generally never tumble-dry it in a dryer. Even on low heat, the warmth can make the fabric shrink, pucker or become otherwise damaged. Instead, air-dry your silk pieces. You can lay them flat or hang them to dry.
Washing on the wrong cycle.
Hot water can also damage silk. Do this instead: Wash silk on a silk or delicate cycle and cool water. Here are some guidelines for washing silk sheets; you can machine wash in cool to lukewarm water.
This one's true - we would never recommend tumble drying silk, because heat can cause silk shrinkage. If you tumble dry your silk pillowcase, you could well find out later on that it will no longer fit over your pillow.
If you frequently sleep with wet hair, we suggest investing in a silk pillowcase. Silk doesn't retain moisture well, thereby allowing your hair to dry faster. More importantly, it's slick and produces less friction when compared with a cotton or flannel pillowcase.
Yes you can. However, whether your pillowcase is silk or cotton, going to bed with wet hair can attract bacteria. If your silk pillowcase absorbs some of your hair product, you can wash this out as easily as a cotton pillow case in most cases, but keeping in mind that silk is more delicate than cotton.
If you find that the sheen of your silk clothing has lost its luster or shimmer and appears to have a white film or looks dull, the silk fibers may have become damaged due to improper cleaning or exposure to too much light or heat.
Never wash your satin garments in hot water, as they will shrink. As we said, if you want them to keep their shine, do not use the dryer for your satin-finish garments.
Silk will shrink in the dryer if the dryer is set to tumble dry medium or tumble dry high, however, silk should never be put into the dryer and should flat dry or be placed on a drying rack to dry.
Once removed from the towel, lay the silk garment out flat on a drying rack without using any clothes pegs. The silk should be dried in the shade, as direct sunlight can cause its colours to fade. Silk tends to dry quite quickly, and you should fine that your garment is dry within around 30-60 minutes.
To restore some of the shine and softness that's been lost, you can give your silk pieces a mild white vinegar bath. White vinegar helps to remove any residual soap in the fibres, and also restores lustre and softness to silk.
Sun and Water Damage. Silk is highly susceptible to damage from the elements. Even a tiny bit of water can leave a visible stain that's impossible to get rid of. And sunlight weakens the fibers of silk, resulting in tearing and fading.
That said, it's worth noting that silk isn't as absorbent as its cotton or linen contemporaries and choosing to wear a silk slip or skirt may result in sweat stains on a very humid day.
Silk is delicate when wet
The strength of wet silk is only 80% that of its dry strength, which means that its fibers can break more easily and stretch out of shape when wet. That's why you need to be careful when washing, wringing and drying silk.
Hang on a line away from sunlight, indoors or outside (sun can cause silk to fade!) We prefer no clothes pins but if needed, use a soft grip style pin to avoid marking/denting your silk bedding. Avoid wooden drying racks which can leech stain or dye onto silk sheets. DON'T put your silk sheets in the dryer*
Wash silk after every few wearings unless it needs freshening and stain removal. Remember that washing your silk clothes at home may put the garments at risk of color fading if cleaned too often. Dry cleaning usually doesn't fade the color of silk clothing as fast as home washing.
Silk is a delicate fabric, and you'll want to make sure it stays beautiful even after you've cleaned it. Washing it at too high a heat can cause it to shrink and damage it. It may be worth getting your silk garment professionally dry cleaned to avoid damage if it's particularly precious to you.
Silk reacts to alkaline detergents. These can cause the silk to become rough and even cause the fabric to break down.
