Title:
ELECTRICALLY CONDUCTIVE COMPOSITE FIBER AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/046296
Kind Code:
A1
Abstract:
This invention provides an electrically conductive composite fiber comprising
an electrically conductive layer formed of a polyester polymer (A) containing
23 to 33% by weight of an electrically conductive carbon black and having a melting
point of 200˚C or above and a protective layer formed of a polyester polymer
(B) having a melting point of 210˚C or above, wherein the difference in
SP value between the polyester polymer (A) and the polyester polymer (B) is brought
to a predetermined value or less and, further, the fiber strength and ductility
are brought to a given range. According to the above constitution, despite the
fact that the amount of the electrically conductive carbon black is only a relatively
small amount, an electrically conductive composite fiber can be provided which
has excellent electricity removing properties, does not significantly cause
a deterioration in electricity removing properties even after wearing for a
long period of time, and is suitable for a clothing field such as wears for clean
rooms and working wears.
