Tufting carpet |
摘要 |
A tufting carpet is described which comprises a tufting base, a pile material and a carpet back and essentially consists exclusively of polyamide 6. Through the use of a chemically uniform material in all components of the tufting carpet, the latter can be recycled as a whole for recovery of the monomeric starting material without the need for separation into the individual components, which has hitherto hampered the recycling of tufting carpets and led to major waste disposal problems.
