Method of making a carpet |
摘要 |
A removable foam backed carpet may be prepared by laminating a non-woven scrim, having a cohesive strength less than the cohesive strength of the foam, to the back of a foam backed carpet. The foam backed carpet is gelled, crushed and vulcanized to produce a resilient backing having a good delamination strength. The carpet is particularly useful when it is cut into tiles. The carpet tile may be easily removed to install wiring of if wear is excessive.
