摘要：PROBLEM TO BE SOLVED: To use used reclaimed polyolefin mainly derived from household waste. SOLUTION: By using used reclaimed polyolefin and unused polyolefin, a polyolefin molded body comprising a used reclaimed polyolefin portion, an unused polyolefin portion and a space, for example, hollow polyolefin fiber and a hollow polyolefin pellet having a layer of a used reclaimed polyolefin layer on the outer side, an unused polyolefin layer on the inner side and a space at the center is manufactured. A method of manufacturing the hollow polyolefin fiber and hollow polyolefin pellet includes: a process of melting a mixture which includes the used reclaimed polyolefin and unused polyolefin and in which 10-90 mass% of the used reclaimed polyolefin is included when total amount of the unused polyolefin and used reclaimed polyolefin is 100 mass%; a process of extruding the molten object to produce an extruded object; a process of cooling the extruded object; and other processes.
