HIGHLY HEAT-RESISTANT POLYESTER DIP CODE AND METHOD FOR PRODUCTION THEREOF

WIPO Patent Application WO/2008/018244

A1

[PROBLEMS] To provide a highly heat-resistant, rubber-reinforcing polyester dip code which causes no melt breakage and can retain its mechanical properties at a higher temperature, particularly a temperature equal to or higher than the melting point of a conventional polyester, and to provide a method for producing the polyester dip code. [MEANS FOR SOLVING PROBLEMS] A highly heat-resistant polyester dip code comprising a polyester fiber having an ethylene terephthalate unit as the main repeating unit and satisfying all of the following requirements (a) to (c): (a) the melt breakage temperature as measured by a heating creep measurement approach is 275˚C or higher; (b) the strength is 4.0 cN/dtex or more; and (c) the degree of elongation under loading of 2.0 cN/dtex is 5.0% or less.
