PROBLEM TO BE SOLVED: To provide a pirn package capable of achieving industrial cloth having excellent surface uniformity very simply and efficiently without needing special manufacturing facilities, winders, etc. by causing a wound yarn pitch in the innermost layer part of the package to be a very wide wound yarn pitch as compared to a conventional pirn package of a monofilament for industrial cloth.SOLUTION: In a pirn package in which a monofilament for industrial cloth with a diameter of 0.05-0.20 mm is wound on a pirn bobbin, the wound yarn pitch in the innermost layer part of the package is 8-35 times the diameter of the monofilament, and the wound yarn pitch increases gradually from the inner layer part to the surface layer part of the pirn package. |
