Abstract: The present invention relates to a biodegradable multi-filament false-twisted yarn having a bulky structure, a production method for the same, and an application for a culture material using the same. The biodegradable multi-filament false-twisted yarn according to the present invention is obtained by the false twisting multiple filaments made from a biodegradable polymer material. By giving the multi-filament false-twisted yarn made from a biodegradable polymer material additional bulkiness of from 150 to 1,000 parts % in addition to the inherent bulkiness and outstanding feeling of softness of false-twisted yarns, the false-twisted yarn of the present invention allows cell culturing in the bulky structure and can suitably be used in cell delivery or drug delivery.

Abstract: The present invention relates to a three-dimensional porous support body, and to a method for manufacturing same. The three-dimensional porous support body of the present invention has a structure in which a biodegradable multifilament false twist yarn to which extra bulk is imparted is inserted into a tube-shaped circular knitwork consisting of biodegradable polymers. The three-dimensional porous support body is porous due to the network structure of the circular knitwork due to the 10-150 µm pores contained in the biodegradable multifilament false twist yarn, and also has superior internal connectivity due to the extra bulk of 150-1000% imparted to the biodegradable multifilament false twist yarn that is fixedly inserted into the circular knitwork. Accordingly, the support body is optimized for cell culturing, cell delivery, and drug delivery since it has a stable three-dimensional structure.
