Title:
THERMOPLASTIC FIBER PACKAGE AND WINDING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2017214185
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic fiber package and a winding method thereof comprising thermoplastic fiber having a low yarn-to-yarn dynamic frictional coefficient, hardly causing yarn drop, excellent in unwindability, as well as in high-order passability during warping and weaving.SOLUTION: A thermoplastic fiber package comprises thermoplastic fiber having a yarn-to-yarn dynamic frictional coefficient equal to or less than 0.60 formed in a cheese shape. An initial winding width is between 60 and 130 mm, with its twill angle increasing as approaching from a winding start part to a winding end part of the package, and a winding start twill angle θ1 and a winding end twill angle θ2 satisfy the following formula: 4.0°<θ2-θ1<7.0°.SELECTED DRAWING: Figure 1
