Given the extensive applications of mop materials in diverse settings, including homes, offices, and industries, rigorous quality testing is essential. While their ease of washing and high absorbency are valuable traits, consistent performance over time is vital. Quality testing ensures mops retain their absorbency and durability, upholding their effectiveness in tasks such as cleaning kitchen surfaces, windows, and furniture. This process identifies and addresses potential issues, maintaining the reliability and functionality of mops across various uses.

Application

COF-S1 is a specialized Mop Cloth Coefficient of Friction Tester for mop and cleaning materials like microfiber mop pads and sponge mops with foam blocks (cellulosic, rubber, or plastic). Friction varies based on usage for liquids, dust, and dry surfaces. The mop's friction coefficient affects its cleaning efficiency and usability. Excessive friction raises labor intensity, while too little hampers cleaning, thus requiring a balanced coefficient for optimal performance.

Formula

The Mop Cloth Coefficient of Friction (COF) is determined by dividing the force needed to move one surface across another by the force perpendicular to the surfaces. It has two kinds: Static and Kinetic. Static COF (µs) is a measure of force required to begin movement, while Kinetic COF (µd) is a measure of force required to maintain movement.

Test Method

To test the Mop Cloth Coefficient of Friction, fix the sample cloth to its aluminum or plastic frame, then place the total assembled part under a certain weight. The block, together with the sample and its frame, is pulled at a speed of 500mm/min, over a 500mm distance. The static and kinetic coefficient of friction are recorded.

The COF-S1 Mop Cloth Coefficient of Friction Tester is a PLC controlled and HMI screen operated equipment with industrial-level stability. Equipped with a user-designated test range and variable test speed, it’s ideal for mop manufacturers to control quality and develop new products. This ensures that mops meet the required standards for efficiency and durability.
