Cleaning mop (1) or cleaning cloth including non-woven material, said mop or cloth being preferably used for floor cleaning and including an outer cleaning layer (5) that includes one or more layers (31) that themselves include natural and/or synthetic fibres, where: the layer (5) has an A thickness of > 2 mm - calculated as the distance between the outer surfaces of the upper layer (4) and of the lower layer (5) - said layer (5) having a combination of elastic properties where Kbel > 25% and Kavl < 10%, these values being measured using the Shirley stiffness tester, a test method as per SS-EN ISO 5084:1996 and a measurement surface of 50 cm2 (circular plate), the measurement being of the relative change in the thickness of the layer (5) in relation to the A thickness and being carried out in accordance with the adaptation of the test method set out below. The material is loaded with a compressive weight of 0.050 kg on the measurement surface. No more than 5 seconds after this, the material thickness is measured (the A thickness). The compressive weight of 1.050 kg on the measurement surface is maintained for 10 minutes. No more than 10 seconds after this, and with the load maintained, the material thickness (B) is measured. The percentage compression after 10 minutes subject to the load (Kbel) is calculated using: formula (I). The compressive weight on the measurement surface is decreased to 0.050 kg and maintained for 10 minutes. No more than 10 seconds after this, and with the load maintained, the material thickness (C) is measured. The percentage compression after 10 minutes subject to this lower load (Kavl) is calculated using: formula (II). |
