Abstract
The present invention is polyester tape yarn excellent in mechanical strength and dye affinity, and, therefore, suitable as fancy work yarn formed through uniaxial orientation of polyester having the ultimate viscosity of 0.7 or more, and has the tensile strength of 1.0 cN/dt or more, the Knot strength represented by the below-mentioned formula (1) of 0.8 cN/dt, the Loop strength represented by the below-mentioned formula (2) of 1.8 cN/dt or more, and the yarn width of 0.5 mm or more.Knot strength:Knot strength(cN/dt)=node strength(N)×100/fineness(dt)  Formula (1)Loop strength:Loop strength(cN/dt)=scratch strength(N)×100/fineness(dt)  Formula (2)
