  • Method for removing aluminum from polyethylene teraphthalate (PET) bottle scrap
    Patent number: 4368274
    Abstract: A method for removing aluminum from PET bottle scrap flakes comprises:(1) mixing the scrap flakes with a solution containing a chemical that reacts with aluminum such that the aluminum in the scrap will completely dissolve into the solution; then(2) decanting off the solution with the aluminum dissolved in it, so as to leave behind PET flake; and finally(3) washing the PET flake.

  • Product comprising blend of hollow polyester fiber and crimped polyester binder fiber
    Patent number: 4129675
    Abstract: Blends of 55 to 97% by weight crimped hollow polyester fiber having a void content of from 8 to 30% by volume and 3 to 45% by weight of crimped lower-melting polyester binder fiber impart advantageous properties to bonded low density batts made therefrom, such as high filling power but low load bulk which makes the batt particularly useful as fiberfill for garments.
