  • Process and equipment for bulk-texturing and simultaneous interlacing of thermoplastic yarns, using heating fluids
    Patent number: 6199250
    Abstract: Process for bulk-texturizing and simultaneous interlacing of medium or high-shrinkage multi-filament yarns carried out with a device in which the yarns are made to pass into single or multiple chambers where the yarns come under jets of steam or other gaseous fluid that cause simultaneously their shrinkage, bulk-texturizing and interlacing.
    Type: Grant
    Filed: October 12, 1999
    Date of Patent: March 13, 2001
    Assignee: G.I.B.A. S.p.A.
    Inventor: Vito Ballarati

    Inventor: Vito Ballarati
  • Process for the production of multifilament yarn drawn in the interlacing stage, from partially oriented thermoplastic yarns
    Patent number: 5634249
    Abstract: A process and apparatus for simultaneously drawing and interlacing partially oriented thermoplastic yarns. The process is carried out in a single apparatus by maintaining the yarn under drawing tension and simultaneously contacting the tensioned yarn with a gaseous fluid at an angle, temperature and pressure such that the yarn is simultaneously drawn and interlaced at the point it is being drawn.

    Inventor: Vito Ballarati
  • Method for on-line process control of yarn package
    Patent number: 5399815
    Abstract: Method for on-line process control of yarns wound upon reels intended for yarn package classification and sorting into homogeneous classes of predetermined quality standards. This method consists in the determination of the specific weight of the yarn bundling on the reel. This value is utilized to check the yarn package compliance with preset standard values of the technological properties, in particular of the dyeing affinity.

    Assignee: Val Lesina S.p.A.
    Inventor: Vito Ballarati
  • Method for preparing warp wound on beams, starting from a series of continuous, partially-drafted thermoplastic yarns
    Patent number: 4669158
    Abstract: A procedure for the drafting and interlacing of a series of continuous, thermoplastic yarns, consisting of filaments which are substantially parallel to one another, in the manufacture of warp wound on beams.

  • Fabrics with a crepe effect constituted by continuous texturized synthetic yarns of high yarn/count/no. of filaments ratio
    Patent number: 4537227
    Abstract: Chain-weft fabrics and knitted fabrics, with a crepe effect, are obtained from continuous texturized synthetic yarns, substantially non-twisted, having a high "yarn count/no. of filaments" ratio, and a high shrinkage under hot conditions, and particularly yarns of 30-160 Dtex comprising filaments of between 5 and 19 Dtex.
