A process for manufacturing substantially 100% nylon 6 carpet provides a nylon 6 face yarn to a nylon 6 support means so that the yarn and the support means form a carpet having a face side which is displayed when the carpet is installed and a back that binds the face yarn to the support means wherein said binding is with molten or dissolved nylon 6.

Recyclable carpet

.epsilon.-Caprolactam is continuously recovered from carpet made from nylon 6 face fibers and a backing. The carpet is fed to a separator to prepare scrap containing nylon 6 and auxiliary materials. The scrap from the separator is fed to a depolymerizing reactor to produce an .epsilon.-caprolactam containing distillate and more auxiliary materials. The .epsilon.-caprolactam in the distillate is separated from other volatiles and purified. The auxiliary materials are also recovered or re-used.

A process for the continuous recovery of .epsilon.-caprolactam provides a carpet made from nylon 6 fibers and having a backing to a separator to prepare scrap containing nylon 6 and waste. The scrap from the separator is fed to a depolymerizing reactor where the scrap is subjected to a depolymerization catalyst, temperatures of at least the melting point of nylon 6 and superheated steam to produce an .epsilon.-caprolactam containing distillate and more waste. The .epsilon.-caprolactam in the distillate is separated from other volatiles therein; and purified.

The present process and apparatus are directed to the continuous spinning and drawing of polyamide yarn wherein an aqueous emulsion spin finish is applied to undrawn yarn and the yarn liveliness on the first or winding godet is significantly reduced by use of a first and substantially unheated godet having an increase in diameter from the first to at least the second yarn wrap prior to drawing and take-up.
