Drum-shaped package formed of poly(lactic acid)-based monofilament

Abstract

A drum-shaped package formed of a poly(lactic acid)-based monofilament 50 wt. % or more of which is constituted from lactic acid monomer, the drum-shaped package being characterized in that the dry heat shrinking stress of the monofilament in the innermost layer section of the package is 0.04 cN/dtex or less. The drum-shaped package formed of a poly(lactic acid)-based monofilament for which gauze fabric quality and higher order passability during weaving are excellent.
