More specifically, the present invention relates to a drum-shaped package made of polylactic acid monofilaments that can provide excellent silk fabric quality and is excellent in high-order passage during warping and weaving.

- a polylactic acid monofilament is produced by a two-step method (Patent Document 1) in which an unstretched yarn is wound once and then stretched, or a one-step method in which a polymer is melted and then directly stretched and wound (Patent Document). 2) There is a straight splitting method (patent document 3) for splitting multifilaments. From the viewpoint of the production cost of polylactic acid monofilament, the one-step method is superior to the two-step method and the straight splitting method.
- Patent Document 2 proposes a one-step process in which a polylactic acid monofilament package has no yarn drop on the end face, and has a drawing tension of 0.04 cN / dtex to 0.35 cN / dtex and a winding tension of 0. There has been proposed a manufacturing method for controlling the pressure to 0.04 cN / dtex to 0.20 cN / dtex.
- Patent Document 3 Since the polylactic acid monofilament described in Patent Document 3 divides a multifilament drawn yarn, there is a problem that fineness spots are likely to occur when a high-density woven fabric is used. Moreover, since it is a straight splitting method, there has been a strong demand for further cost reduction in terms of manufacturing cost.
- An object of the present invention is to provide a drum package made of polylactic acid monofilaments that overcomes the above-mentioned problems of the prior art, is capable of obtaining excellent silk fabric quality, and is excellent in high-order passage during weaving. .

The optical purity of D-lactic acid or L-lactic acid in the polylactic acid polymer decreases, the crystallinity decreases and the melting point drop increases.
- the optical purity is preferably 90% or more in order to improve heat resistance.
