Definitions

• the present invention relates to the technical field of maintenance articles for cleaning floor surfaces as well as cleaning devices for the implementation of such maintenance articles.
• cleaning articles comprising, according to their lower cleaning surface, a textile consisting of loops and / or microfibre bristles and fibers having a titration greater than 1 dtex, also referred to as scraping fibers.
• Microfibers are known to form an extremely dense capillary network which gives them excellent liquid absorption and good recovery of smaller particles such as dust.
• Microfibers in the present text include all fibers whose titration is less than 1 dtex.
• the loops or bristles formed by fibers having a titration greater than 1 dtex confer an abrasive or scratching power to said maintenance article in order to detach any dirt disposed on the surface to be cleaned.
• microfibres have an absorbing power such that if they constitute the entire cleaning surface, the maintenance article handled remotely using the tray of a broom adheres so strongly on the floor to be cleaned, especially when the maintenance item is wet, that the user no longer manages to move the article (it speaks of "suction effect" generated by the capillary network).
• scraping fibers having a titration greater than 1 dtex are alternately arranged with said microfibers.
• Scraping fibers having a higher titration than microfibres are stiffer and form fulcrums according to the so-called cleaning surface on which the maintenance article can slide on the floor surface to be cleaned.
• such maintenance articles comprise according to their lower surfaces - intended to form the so-called cleaning surface coming into contact with the ground - about 50% by weight of microfibers with respect to the proportion by weight of fibers on said lower faces, the remainder being fibers having a titration greater than 1 dtex.
• These maintenance articles may be laminated with a foam or comprise other absorbent textile panels disposed on their upper faces.
• Such maintenance articles are thus limited in the amount of microfibers that their cleaning surfaces may have as well as in their fineness (or titration in dtex).
• the finer the microfibers i.e., the lower their titration (dtex)
• microfibers have a higher absorption and recovery capacity than scratching fibers, there is therefore an interest in seeking the optimization of their quantity and / or fineness according to the cleaning surface of the articles. interview.
