<p>PURPOSE:To expand rings and to increase microorganism holding capacity by knitting pile yarn into a base fabric together with yarn for an open chain structure so as to form many rings along the longitudinal direction and by using the resulting knitted fabric. CONSTITUTION:Pile yarn 13 is knitted into a base fabric A together with yarn 10 for the open chain structure so as to form many rings 14 along the longitudinal direction. The resulting narrow knitted fabric B is used as a core material 15 and the many rings 14 are partially raised from the peripheral surface 15a of the core material 15 to produce a microorganism holding bed C. Curled parts 12 positioned under the rings 14 are lifted up by twisting and the rings 14 are raised by pressing from the lower parts. The rings 14 are expanded and the microorganism holding capacity is increased.</p> |
