2. Coupled with the unique air permeability and moisture permeability of silk itself, silk is smoother to the touch, cool but not warm, warm but not dry.

3. Medical field: Silk fibroin and sericin are components of spun silk. After being treated with concentrated sulfuric acid, the same substance as heparin can be obtained, which has anticoagulant activity and delays coagulation time, and can be used to develop blood testing equipment or antithrombotic materials. By changing some processing conditions in the same way, spun silk rich in water absorption and water retention can be processed into advanced water-based materials or other physiological health care products.
4. Industrial field: The silk powder processed into particles can be used as an additive for cosmetics or health food, and can also be made into silk paper containing silk powder or food fresh-keeping packaging materials and antibacterial silk materials. Silk fibroin film can be used not only to process contact lenses, but also to mix silk powder as fine as 0.3μm with resin to develop a new product called silk leather.

In cold weather, it can reduce the thermal conductivity and keep warm better than leather and cotton. In hot weather, it can discharge excess heat and keep the temperature in the quilt comfortable.
(3) The silk quilt itself has strong strength and extensibility, and it is a warp and weft mesh structure, which eliminates the matrix displacement or hole breaking phenomenon during the use of the quilt, and can be used for a long time, maintaining a comfortable and fluffy feeling.
