。As mentioned above, in the technique of applying an epoxy compound to polyester*1t and subsequently heat-treating it, the epoxy compound adheres to the surface of the heating roller used for heat treatment, and the epoxy copolymer resin is deposited on the surface of the heating roller. A film is formed. When polyester fibers are wound around a heating roller on which this resin film is formed and subjected to hot stretching or heat treatment, the thermal conductivity of the Bossester fibers increases as the frictional resistance between the heating roller and the polyester fibers increases. decreases,
The physical properties of the resulting polyester fibers, particularly their strength, elongation, and adhesion to rubber, change, making them less homogeneous, and single yarn breakage increases on the heating roller, increasing the frequency of cutting the entire yarn. It had drawbacks. Furthermore, if a fat film is formed on the surface of the heating roller and it becomes clear that the thermal conductivity has decreased, the heating roller must be cleaned. However, it has the drawbacks of lowering the temperature and requiring removal of the 161 oil film.
