Nonwoven
- Any carpet manufactured by a method other than weaving, but particularly
those composed of fibres held together by chemical, mechanical,
adhesive or fusion means;
- Any primary backing material manufactured by a method other than
weaving (example - Typar® carpet backing).

Nylon
A petrochemical-based fibre invented in 1938.
There are two basic types of nylon: Type 6,6 nylon and Type 6 nylon.
Nylon is produced in bulked continuous filament for use in loop carpets
and cut pile carpets; and staple nylon which is spun into yarn for
use in cut pile carpets. Nylon is the dominant fibre choice for commercial
use due to its wear characteristics.
|
Nylon flake (or chip)
Polymer that has been cut into small pieces for storage
or for immediate melting in the fibre extrusion process.
|
Nylon—Type 6
Made from one base ingredient: caprolactam. Compared
to Type 6,6 nylon, Type 6 nylon accepts dye at a faster rate. The
more open molecular structure of Type 6 nylon allows dye stuffs (and
stains) in more readily. Common spills and stains such as coffee,
soda, foodstuffs and medicine will stain Type 6 nylon more readily
than Type 6,6, whether solution dyed or conventionally dyed.
|
Nylon—Type 6,6
Made with two base chemical ingredients:
adipic acidand hexamethylene diamine. Type 6,6 nylon
has a tighter molecular structure, making it harder, more resilient
and more resistant to stains than Type 6 nylon. In the U.S., where the
highest commercial carpet standards are set, over 60% of all nylon carpets
installed are Type 6,6 nylon.
