Abstract
This invention provides a punch carpet that is biodegradable and can be manufactured more easily, as well as a method for manufacturing the punch carpet. [Solution] The punch carpet has a single-layer structure in the nonwoven fabric region. The nonwoven fabric comprises a plurality of entangled rayon fibers 11 and polylactic acid fibers 12, and a binder 13. The binder 13 fixes the rayon fibers 11 and polylactic acid fibers 12 and is made of polylactic acid. The rayon fibers 11 and polylactic acid fibers 12 are non-melting at the melting point of the polylactic acid that constitutes the binder 13.
