Yarn for cell culture scaffold, ply yarn comprising same and fabric comprising the same

A ply yarn for a cell culture scaffold, comprising:

• a slitting yarn with a plurality of twists and fiber grooves, wherein the slitting yarn has a fineness of 0.01 to 30 denier and is a nanofiber web having a basis weight of 0.1 to 20 g/m2 in a three-dimensional network structure cut into multiple strands to have a width of 0.1 to 30 mm;
• and
• the fiber grooves which are spaces formed between the twists and configured to provide three-dimensional growth spaces and migration paths for cell,
• wherein the ply yarn comprises a plurality of macrotwists at a twist number of 100 to 5,000 twists/meter (T/m) and a twist angle of 20° to 60°, and macrofiber grooves between the plurality of macrotwists, wherein the ply yarn has a fineness of 0.5 to 1,000 denier and the macrofiber grooves are configured to provide three-dimensional growth spaces and migration paths for cells,
• wherein the fiber grooves are formed continuously in the longitudinal direction of the ply yarn for a cell culture scaffold, and
• wherein the ply yarn for a cell culture scaffold comprises microfiber grooves, which are spaces between the slitting yarn strands, formed on an outer surface of the ply yarn.
