  • Process for the production of filament yarns with statistically distributed, broken individual filaments
    Patent number: 4054025
    Abstract: The invention relates to the production of yarns with individual filaments broken in a purely random sequence. This object is achieved by initially interlacing the uniform filament yarns either during spinning and before winding or between the winding bobbin and the drawing zone and subsequently subjecting parts of the outer layers of the interlaced filament strand to brief heat treatment on a contact heater before stretching.

  • Preparation of high molecular polyesters of 1,4-butanediol
    Patent number: 3940367
    Abstract: Low-molecular polyesters prepared by the condensation of diols and dicarboxylic acid dialkyl esters show a substantially improved capactiy to undergo polycondensation in a susequent polycondensation below the melting point if said low-molecular polyesters are prepared from pressure trans-esterification products by polycondensation in the melt.
