摘要
The invention concerns a method for making industrial continuous filament yarn by entangling a polyester multifilament yarn at high temperature, under yarn traction force less than 140 cN. By means of a tangling cop tube consisting of a body (1) provided with a perforated plate (2) and a deflection plate (3), heat is directly transmitted to the polyester filament and the air passing through the cop tube body (1) is directly transmitted to a metal block (8) with high thermal conductivity directly connected to the deflection plate (3). In the device for implementing said method, the deflection plate (3) is directly connected to a metal block (8) with high thermal conductivity, wherein a bore (7) is provided for housing a heating element. The polyester continuous filament designed for spinning applications, with a yarn count of 500-2000 dtex, has a resistance of at least 70 cN/tex for a breaking elongation less than 24%, and a knot strength higher than 80% and a spacing between 2 knots more than 4.0 cm.
