Latex-free tufted carpet has second backing which is connected to carpet via intermediate nonwoven

摘要

The nonwoven is made of a first set of thermoplastic or non-thermoplastic fibers and a second set of thermoplastic fibers, and the second backing has a similar fiber structure. If the first set of fibers of the nonwoven are thermoplastic, they have a higher melt point than the second thermoplastic fibers. If the first st of fibers of the second backing are thermoplastic fibers, they also have a higher melt point than the second thermoplastic fibers, which are present in a 0-20% proportion to the first set of fibers.
