3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Low melting point polyester composite fiber lowmeltingpointpolyestercomplexfiber In the component to a certain percentage from the melt mixing of the two components, the inner core phase (conventional polyester HMPET) evenly coated skin deep (modified poly Ester LMPET), the composite fibers are formed and ejected from the nozzle plate. Wherein the melting point is significantly lower than skin deep portion of the polymer relative to the inner core portion Melting point score. Principle 4 In polyester fibers identified as the basis, depending on the characteristics of low melting point polyester composite fiber, followed by microscopic observation experiments, fusion bonding test Inspection, melting point test, the test results by the provisions of Appendix A were compared, to achieve identification of a low melting point polyester composite fiber.
