发明名称 Cleaning implement
摘要 A cleaning implement includes a fabric layer made from a splittable conjugate fiber, a sponge wiper layer made of melamine foam, and a reinforcing layer made of a non-melamine foam material and disposed between the fabric and sponge layers. The non-melamine foam material has higher water-absorbing and elastic properties than the melamine foam.
