Choose Between Hand-Washing and Machine-Washing
Silk can either be washed by hand or in the washer. If you decide on using the washer, use the gentle cycle, and place the silk pillowcase in a mesh laundry bag. This will protect it from snags from zippers, hook and loop fasteners, or rough spots in the machine.
When hand-washing, go for a gentle touch with no twisting or wringing. Silk fabric is strong when it's dry, but much weaker when fibers are wet.
Use a Gentle Detergent
Some detergents are simply too harsh for silk and will leave it feeling rough and scratchy. Choose a gentle detergent, like a wool wash, that can clean well but protect the fibers.
For hand-washing, use about one teaspoon per sink basin. In the washer, two tablespoons to one-fourth cup should be used depending on the size of the laundry load.
You may find makeup or bodily fluids on your silk pillowcase, so always check for stains before you toss it in the washer or hand-wash. Simply work a tiny dab of the detergent into the stained area with your fingers. Let the detergent work on the area for at least 15 minutes before washing. This will give it time to break apart the stain molecules. Then wash as usual.
Use Cold Water
Cold water is the best choice for washing silk. Hot water can distort the fibers.
Add Vinegar to the Rinse Cycle
Whether you are hand-washing or using the washer, always add some distilled white vinegar to the rinse water. The vinegar will help remove any soapy residue in the silk fibers and leave it silky smooth.
For hand-washing, use about one-fourth cup in the rinse water. In your washer, add one-half cup to one cup of vinegar to the fabric softener dispenser depending on the size of the load.
Avoid a Hot Dryer
Silk and high temperatures are not compatible. The best way to dry your pillowcase is on a drying rack, away from direct heat sources and sunlight. If you are in a hurry, tumble dry on the lowest heat setting of your dryer, and remove the pillowcase while still slightly damp. Let it finish by air-drying.
Storing Silk Pillowcases
When storing silk pillowcases, never fold into a tight square with sharp creases. This can weaken fibers. Create a soft fold or roll the pillowcase before placing it on a shelf where it will not be crushed.
If you feel your pillowcase is overly wrinkled, it can be ironed on the lowest temperature setting on your iron. Always use a pressing cloth or a clean, white cotton cloth between the iron and the silk to prevent scorching. Burned fibers cannot be restored. Always iron flat, and never press in sharp creases.
What Are the Benefits of Silk Pillowcases?
Silk is a natural fiber produced by silkworms that feed on mulberry leaves and then spin a cocoon made of long, lustrous fibers. The cocoons are boiled in water to release the fibers that are then spun into thread for weaving. Silk fabrics are strong, resilient to wrinkling, absorbent, hypoallergenic, and can be woven to a smooth finish. Those qualities make silk fabrics perfect for bedding.
- As a natural fiber, there are fewer chemicals involved in the production of the fabric than man-made fabrics like microfiber, which is made from petroleum-based materials.
- Silk fibers help the skin retain moisture, which can help prevent dryness.
- The smooth finish of silk helps reduce hair breakage and tangling.
