Class Code: 2288
Per NCCI's Scopes Code Description:
Code 2288 is applicable to the manufacture of felt or felt-like material. Felt is described as a mat-like material which is manufactured by the pressing of raw materials into desired dimensions. The raw materials consist principally of raw wool, cotton, nylon, textile scraps, etc. The raw materials are mixed in the required proportions and, after picking and dusting, they are passed through breaker, intermediate and finisher cards where the material is carded and laid in layers forming felt. The felt is then pressed and hardened by a hardening machine and, after fulling, is scoured and washed, dyed and finally dried. After drying the felt is pressed and trimmed in shearing machines and is folded or rolled preparatory to shipping. Products subject to Code 2288 include automobile floor and trunk mats, automobile interior trim and headliners and padding used as filler for sleeping bags and mattress pads.
The manufacture of non-woven air conditioning filter media is assigned by analogy to Code 2288.
