Brochure

The filaments in Fusible Polyester yarns are comprised of two different melting temperature polymers in a coaxial, or core-sheath, configuration. The sheath polymer melts at about 100° C less than the core polymer, allowing the tensile properties of the core to remain intact. Thermal bonding is achieved from about 160 through 190° C.

Fusible Polyester yarns can be heat activated to...

• bond fibers together
• seal yarn or fabric interstices
• bond materials together
• laminate film to fabric
• improve fabric ravel and fray resistances
• improve sewn seam performance
• prevent yarn slippage
• seal knots
• weld splices
• mold fabrics
• pleate fabrics

Fusible Polyester is well suited for

• Knitting
• Braiding
• Weaving
• Sewing
• Laminating
• Molding
• Pleating
