  • Melt spinning of synthetic fibers
    Patent number: 4446299
    Abstract: Improved synthetic spun fibers are disclosed. The fibers have improved properties, especially with respect to the strength-elongation properties, the texturability by means of friction units or gas jet turbulence and the subsequent treatability of the fibers without the interpolation of a separate stretching operation. The fibers are produced from polyester and polyamides.
