About one-third of a person's life will come into contact with a pillow. Many times when you wake up, you will find annoying marks on your face. Have you ever thought that these marks will become wrinkles?
What kind of fabric is the best for pillow case? Polyester, cotton, tencel, modal or silk? We may be sleeping in pajamas, but there is only one place where you must be naked, that is your face, and among all the fabric properties, silk is the most suitable fabric for sleeping naked.
Facial skin damage is related to fabric friction
Silk is made up of protein fibers, which have excellent biocompatibility with human body and smooth surface. The friction stimulus coefficient of silk to human body is the lowest among all kinds of fibers, only 7.4%. When our delicate skin meets the smooth and delicate silk, it cares for every inch of the skin with its unique soft texture and the curve of the human body.
The delicate skin is the retention of moisture
Silk is enriched with hydrophilic groups such as amine groups (-CHNH) and amino groups (-NH2). Due to its porosity, it is easy to diffuse water molecules. It absorbs moisture or emits moisture in the air and maintains a certain amount of water. Under normal temperature, it can help the skin retain a certain amount of moisture without making the skin too dry.
Anti mites and anti bacteria
Bacterial mites on the fabric cause skin irritation.
Silk sericin has ingredients to prevent mites and molds from breeding, can prevent harmful organisms from corroding silk. At the same time, silk is close to the body, no static electricity, no dust, and more clean. Therefore, when our face is in contact with the silk pillowcase, it is healthier than other fabrics, and it is more beneficial for the maintenance of the face. Silk is known as the "Fiber Queen" for its unique excellent hygroscopicity, antibacterial property, and its extraordinary elasticity, softness and smoothness. It is recognized as the softest and healthier natural fiber.
The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has a good anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after absorbing ultraviolet rays, the silk itself undergoes chemical changes, so that the silk fabric is easily yellowed under the illumination of sunlight.
