High Tenacity Polyester Yarn

A yarn containing filaments made from synthetic polymers has a cross-section having at least 5 vertices, a titer of 1 to 7 dtex and a tenacity of at least 60cNtex. The filaments of the high tenacity yarn preferably have a cross-section having 5 to 8 vertices, possibly with indentations between the vertices. The high tenacity yarns has high durability, toughness and chemical resistance, and withstands extremely hot environments that can stress conventional multi-filaments to their performance limits and is also available in different variant like normal shrinkage, low shrinkage & super low shrinkage depending upon the suitable end-use.
