"Mulberry silk quilt", also known as "silk quilt", refers to bedding-type bedding containing more than 50% mulberry silk (tussah silk) used as a filler. Depending on the type of filler, one hundred percent of the pure silk is called "pure silk." Below this standard, but above 50% is called "hybrid". According to the different processing methods, it can be divided into "manual" (hand-drawn cotton, hand-stripped cotton) and "mechanism". According to the source of raw materials, it can be divided into "mulberry silk" and "silk silk".
