If you compare linen vs cotton sheets in terms of breathability, another major difference emerges — linen will keep you much cooler at night because of its longer fibers and, therefore, looser weave. Air can pass through linen more easily, keeping your body cool. Cotton, as previously discussed, can also be perfect for warm sleepers (in the case of percale bedding), but linen definitely has the edge over it.
Silk:Silk is a natural protein fiber, produced by insects to form their cocoons. Silk can be produced by a number of different insects, but the most commonly used is silk from the mulberry silkworm. The fiber produced by these insects is harvested, unwound, and twisted together to form yarn, which can beused to make fabric.
