CARBON FIBER PACKAGE AND CARBON FIBER PACKAGE BODY |
摘要 |
A carbon fiber package in the form of cheese winding or inside-pull package is made of carbon fibers having a fineness of at least 25,000 deniers. The outer diameter, the bobbin diameter or inner diameter of the package, and the winding width are in specific ranges. A square end type package has a yarn width per fineness, an angle of wind at the start and end of winding, and a winding irregularity in specific ranges. A carbon fiber package body has a mean bulk density in a specific range. Troubles and disadvantages during use are eliminated, a high winding density is achieved, and winding collapse hardly occurs.
