  • Spandex covered tightly with shrinkable nylon and process for producing it
    Patent number: 7152390
    Abstract: A process is provided for making a yarn with improved properties, such as lowered susceptibility to picks and snags. The yarn consists of a spandex core that is tightly covered with a nylon fiber, which tight covering is achieved by heat treatment. A knitted fabric is further provided, that is made of yarn consisting of a spandex core and a nylon fiber, which has low susceptibility to picks, as well as to tears during its production and its use.

  • Process for the manufacture of polyamide yarns dyeable in melange shades
    Patent number: 6524503
    Abstract: A process for the manufacturing of a differentially dyeable yarn includes the steps of: a) producing two polymers having a different concentration of amine end-groups; b) spinning yarns from said two polymers; and c) producing a yarn by intermingling said spun yarns made from said two polymers, in texturing, or draw twisting, or draw winding processes.
