The Qmax value is a measure of a fabric's heat transfer rate, representing the maximum amount of heat that can be transferred through one square meter of fabric in one second. Fabrics with higher Qmax values have better cooling performance, as they can transfer more heat away from the body.
A 2019 study published in the Textile Research Journal investigated the effects of cool silk bedding on sleep quality and comfort. The study involved 60 participants who slept on cool silk bedding for one week. Results showed that participants experienced better sleep quality and felt more comfortable during the night compared to when they slept on traditional cotton bedding.
A 2020 study published in the Journal of Textile Science and Technology compared the cooling performance of cool silk fabric with a Qmax value of 0.36 to traditional cotton fabric. Results showed that cool silk fabric had significantly higher cooling rates and lower thermal resistance compared to cotton, indicating better cooling performance.
Studies have shown that cool fabrics with a Qmax value of 0.36 can improve sleep quality and comfort for hot sleepers. These fabrics help regulate body temperature by absorbing and dissipating excess heat, preventing sweat buildup, and providing a cool and comfortable sleeping surface. As a result, sleepers are less likely to experience night sweats, overheating, and discomfort, leading to more restful and rejuvenating sleep.
