Zusammenfassung:	The utility model provides a combined felt and a combined heat preservation cylinder, and relates to the technical field of single crystal furnace thermal fields. The combined felt comprises a supporting piece and a soft felt. The supporting pieces are annular, one end of each supporting piece is a first splicing face, the other end of each supporting piece is a second splicing face, and any two adjacent supporting pieces are spliced through the first splicing faces and the second splicing faces. The soft felt is detachably connected to the inner side of the supporting piece, and the supporting piece can limit the soft felt to move in the axial direction of the supporting piece. The movement of the soft felt in the axial direction of the supporting piece is limited through the supporting piece, so that the soft felt is not prone to loosening in the process of lifting the supporting piece and the soft felt. The combined heat preservation cylinder comprises a heat preservation cylinder body, a soft felt is arra
