Normally, cocoons of Mulberry silkworm are unraveled to make spindles of single-strand silk threads for later use. In the case of making silk comforters, however, this process is replaced with another in which the cocoons are stretched many different times using proper instruments and with hands to eventually form a thin, flat layer of tangled silk threads of the required dimensions. Tens or even hundreds of these layers are then stacked on top of each other until proper weight has been achieved, and the result is the silk floss filling in a silk comforter. The filling is then enclosed with a cotton or silk shell and tacked on the sides to the shell to prevent the filling from clumping up or moving around, and the result is our extremely light-weight and breathable silk comforter.
Since the silk floss filling is fitted to the comforter shell and not stuffed, we call our comforters “silk-fitted”.
