Are Mulberry Silk Duvets Good for Hot Sleepers?<\/h1>\n
<\/div>\n
\n
\n

Feel hot and sticky in bed? Do you keep turning and struggle to fall asleep? A mulberry silk duvet<\/a> can help create a more comfortable sleep environment. This guide explains how it can help your bed feel dry, light, and comfortable.<\/p>\n

Quick Answer: <\/span>Mulberry silk can absorb water vapour and release it as the air becomes drier. Its fine fibre structure also supports airflow and moisture movement. In a duvet, it can help reduce a damp, stuffy feeling for hot sleepers<\/a>. Silk weave, fabric weight and bedding layers also matters for a cool sleep.<\/span><\/p>\n<\/div>\n

Fibroin and Sericin in Mulberry Silk<\/h3>\n
\n

Mulberry silk<\/a> is a natural, sustainable fiber with the clear core and outer layer. Fibroin<\/a> protein forms the core and makes up about three quarters of the fiber. Sericin<\/a> forms the outer layer.<\/p>\n

The fibroin protein contains water loving groups that can bind with water molecules. This gives silk good moisture absorption. It can absorb sweat from the skin and help create a dry, comfortable sleep environment. Much of the sericin is removed during degumming, which makes the silk bedding softer.<\/p>\n

Fibroin and sericin contain 17 to 18 amino acids, about 97% pure protein. They are similar to the proteins found in human skin and collagen. Mulberry silk has a good compatibility with the skin, which makes you feel smooth and gentle.<\/p>\n<\/div>\n<\/div>\n

\n

How Silk Fibre Structure Moves Heat and Moisture<\/h3>\n
\n

Silk is featured with multiple layers of tiny structures<\/a>. Small spaces between the fibers allow water vapor and air to move through. That\u2019s the reason why a mulberry silk duvet can help moisture move through the filling. The air between the fibers can also help reduce sudden changes in temperature<\/a>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

Moisture Regain in Mulberry Silk<\/h2>\n
<\/div>\n
\n
\n

Moisture regain<\/a> is the percentage of moisture in a fibre compared with its dry weight. Simply speaking, it shows how well a material can absorb moisture from the air. If moisture regain is too low, fibres will become brittle and more likely to build up static. If too high, the material would be damp, heavy and less stable. Mulberry silk absorbs water vapour and release it when the air becomes drier.<\/p>\n<\/div>\n<\/div>\n

Breathability and Moisture Vapour Transmission of Mulberry Silk<\/h2>\n
<\/div>\n
\n
\n

To figure out a fabric\u2019s breathability and moisture vapour transmission rate, you need to know how heat and moisture move between the fabric and the skin. There is a small air space between the skin and the fabric. Our body releases heat, water vapour, and sweat during sleep. If they can\u2019t escape in time, the bedding may feel hot, damp, and sticky.<\/p>\n

Breathability describes how easily air passes through a fabric. Moisture vapour transmission measures the fabric\u2019s ability to release water vapour. Moisture regain is only the first step. Once moisture is absorbed by the fibres, it still needs to move through the fabric and gradually evaporate. These performances are affected by fibre structure, yarn, weave, thickness, and surrounding conditions.<\/p>\n<\/div>\n<\/div>\n

Silk vs Cotton<\/h3>\n
\n

We have mentioned the small spaces between mulberry silk structure. Research shows, at comparable low surface densities, silk showed higher air permeability and moisture permeability than cotton.<\/p>\n
