23 Jul Apparatus for preparing non-woven fabric by fused mass and solution centrifugal spinning
Abstract
The utility model relates to a nonwovens preparation device by using a melt and solution centrifugal spinning. The device uses the melt and solution centrifugal spinning to prepare the nonwovens. The prepared nonwovens have the advantages that the mechanical strength is good, the range of the fiber dimension is wide, the aperture is big, and the porosity is high and the like, the device is particularly applicable to the preparation of a frame material of polyester biodegradable tissue engineering. Compared with a porous-sponge frame, the surface area of a fiber nonwoven fabric (fiber felt) is large, the porosity is higher, the permeability of the frame is better, but compared with a superfine fiber nonwoven fabric prepared by using an electrostatic spinning, the aperture of the fiber nonwoven fabric with a fiber frame is big, the structure is convenient for the regeneration of a cell and a tissue, the distribution of the fiber dimension is wider, meanwhile the fiber nonwoven fabric has a micron, submicron and nanometer fiber, the mechanical properties and the degradation time thereof are all different, the fiber of the frame is gradually degraded from small to big after the frame is implanted into a body, a space is gradually provided for the growth of the tissue, and the nonwovens being used as a repair material for the tissue is more reasonable.
