  • Preadhered melt spun spin-drawn polyester filaments
    Patent number: 5403661
    Abstract: The present invention discloses preadhered, melt-spun, spin-drawn polyester filaments having improved adhesive properties towards rubber and processes for making the same. The process for making these filaments include the following steps:(a) spin-drawing polyester filaments at an up-take speed ranging between about 2,000 and about 6,000 meters per minute by using an integrated spin-drawing process; and(b) immediately after spin-drawing, applying to the polyester filament a composition which has simultaneously about 0.05 to about 0.5% by weight of a polyepoxide and about 5 to about 140 ppm of a tertiary amine with linear functional groups.The resulting polyester filament has a minimum adherence towards rubber in the Strip-test of about 16.0 to about 21.5 daN.
    Type: Grant
    Filed: March 15, 1994
    Date of Patent: April 4, 1995
