Abstract
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.
Claims1
A process for manufacturing substantially 100% nylon 6 carpet, comprising:
- a) weaving a nylon 6 face yarn into a nylon 6 support means so that the yarn and the support means form an unbound carpet having a face side which is displayed when the carpet is installed and a back;
- and
- b) then passing the unbound carpet over a textured calendar roll such that the unbound carpet and the textured calendar roll contact each other at spots and spot melting nylon 6 at the spots where the textured calendar roll contacts the unbound carpet to bind the face yarn to the support means and form a bound carpet which is substantially 100% nylon 6 wherein said textured calendar roll is maintained at a temperature sufficient to spot melt nylon 6 at said spots where the calendar roll contacts the unbound carpet.
