Title: Spun yarn and method for producing the same
Inventor: KATAKI SHUICHI
IPC: D06M101/16
Filed: 2001-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing spun yarns capable of producing spun yarns having good hand feeling with solving a problem that oil is usually added during cotton mixing to bring spinnability better, but the added oil negatively acts to bulkiness, antifouling properties and the like of the spun yarns by keeping a good spinning condition as that of the usual one while considering the environment.
