Mulberry silk is a continuous long fiber coagulated by the secretion of silk liquid when the cocoon is formed by the cooked silkworm, and it is also called “natural silk”. Like wool, it is one of the earliest animal fibers used by humans. According to different foods, it is divided into silkworm, tussah silkworm, cassava silkworm, camphor silkworm, willow silkworm, and sky silkworm. The silk sliver drawn from a single silkworm cocoon is called cocoon silk, which is made of two single fibers bonded and covered with sericin.
The silk fiber is the protein fiber, sericin and silk fibroin are its main components, of which silk fibroin accounts for about 3/4 and sericin accounts for about 1/4. Sericin and silk fibroin are composed of 18 kinds of amino acids and contain about 97% pure protein.
The duvet made of mulberry silk is more close-fitting, and the natural characteristics can nourish the skin more. It is a very good duvet material.
The mulberry silk duvet must be very comfortable in summer. No need to explain this. The density of silk is very small, that is, the volume per unit weight is very large, which exceeds that of cotton and wool. In addition, the fluffy and elasticity of refined and cooked silk are excellent. Therefore, there is a lot of uncirculated air in the silk fiber flakes, and the warmth retention is much higher than that of other textile materials. In other words, it is more suitable for winter use! Generally, 4-5 catties of the duvet on top of three catties of silk duvet is no problem.
Moreover, the 18 kinds of amino acids in pure natural silk are similar to the human body protein composition. They are breathable, soft, soft, hygroscopic, close to the body, and healthy. These amino acids have the effects of stabilizing human nerves and preventing insomnia and are more comfortable, softer, and more suitable for human health requirements than other textile materials. Among them, serine can nourish the skin, prevent skin aging, etc., can clean and protect the skin, and increase the vitality of skin cells. Especially effective for sensitive skin, delicate skin of infants and young children, and itchy skin of the elderly.
