If the silk becomes heavy and thin, you can dry the water in the cup and beat it until it is loose. Or send the quilt to renovate, remove the broken silk in the silk quilt, add new silk and lay it again. Through this process, the silk quilt will be more fluffy and soft.
First of all, we should make it clear that the silk quilt will not sink for no reason. This phenomenon must be caused by the increase of some components in it. Generally, it is because of the increase of moisture or dust.
In this case, we can choose a weather with mild sun, and then put the silk in the sun for about two hours. In this way, the moisture accumulated in the silk quilt can be dried, and then the silk quilt can be patted until it is loose, and the fine dust can be patted out.
Or you can send the silk to be renovated. The renovation is through the process of decomposing, sorting, re drawing and positioning the silk, removing the broken silk in the silk quilt, adding new and good silk and laying it again. Through this process, the silk quilt will be more fluffy and soft.
