发明名称 Disposable cleaning implement
摘要 The present invention relates to an improved disposable cleaning sheet for removing debris, especially hair from a non-smooth or rough surface, especially fibrous type surfaces such as carpeting or upholstery. The cleaning sheets comprise a fibrous substrate and a plurality of protrusions extending from strand elements embedded within fibrous substrate. The cleaning sheets use the protrusions to dislodge the debris from the surface being cleaned, and the fibrous substrate captures the dislodged debris without a backing for the protrusions interfering with the particle capture of the fibrous substrate. Further, the protrusions are firmly embedded within the fibrous substrate such that they cannot be dislodged from the substrate in use.
