The clean room has extremely high requirements for environmental cleanliness. If the mop has fiber shedding, it will directly destroy the dust-free environment and affect the production quality. In terms of design, the clean room mop needs to start from material selection, process treatment, structural optimization, production process control, use and maintenance design, testing and verification, and auxiliary design to avoid fiber shedding and polluting the environment in all aspects.
In terms of material selection, the clean room mop needs to use special low-dust materials. Ordinary mops often use cotton or ordinary chemical fiber materials, which are very easy to produce fiber shedding during use. Clean room mops mostly use polyester filament fibers, which do not have short fiber ends, which reduces the possibility of fiber shedding from the root. In addition, there are specially treated ultra-fine fibers with a tight structure, smooth surface, and low friction between each other. During the wiping process, the fibers will not be easily broken and shed due to friction, which provides a basic guarantee for avoiding pollution.
The process treatment link is crucial to preventing fiber shedding. The edges of traditional mops are mostly cut in a simple way, which is very easy to cause burrs and cause fiber scattering. Clean room mop will carry out special treatment on the edges, such as using hot-melt edge sealing technology, which melts the edges of the mop cloth at high temperature and then bonds them together to form a solid edge, effectively preventing fibers from falling off from the edges. There is also an ultrasonic welding process, which uses high-frequency vibration to fuse material molecules with each other, which can not only ensure the sealing of the edges, but also enhance the overall strength of the mop cloth, further reducing the risk of fiber shedding.
In terms of structural design, clean room mop also has unique considerations. The connection method between the mop cloth and the mop rod abandons the traditional simple bundling or sewing, and adopts a more stable snap-on or magnetic connection. This connection method is not only convenient for replacing the mop cloth, but also during use, even if it is subjected to a large tensile force, the mop cloth will not loosen or deform, thereby avoiding fiber shedding due to fabric displacement friction. At the same time, a lining cloth or reinforcement layer is added to the back of the mop cloth to enhance the integrity and tear resistance of the mop cloth, so that the fibers are more firmly fixed in the cloth.
Strict control of the production process is also key. From the inspection of raw materials entering the factory, the quality of the fibers must be strictly controlled to ensure that each batch of materials meets the low dust generation standard. During the production process, the environmental cleanliness of each link such as cutting, sewing, and processing is strictly controlled to prevent external dust and impurities from adhering to the mop, and to prevent the fibers from being damaged and falling off due to improper operation during the processing. After each process is completed, a detailed inspection must be carried out to promptly discover and deal with the potential risks of fiber shedding.
In terms of use and maintenance design, clean room mop has also been optimized in a targeted manner. The mop cloth structure is designed to be easy to disassemble and install, so that it is convenient to replace and clean it in time after use. At the same time, the mop is equipped with special cleaning tools and cleaning processes to avoid fiber shedding due to excessive rubbing and pulling during the cleaning process. For example, mild detergents and special cleaning equipment are used to remove stains by gentle stirring and rinsing, rather than strong friction. In addition, a storage device for the mop will be designed to keep the mop dry and flat when idle to prevent the fibers from loosening due to moisture and wrinkles.
The testing and verification link provides the last line of defense for the quality of the mop. After the mop is produced, professional testing equipment and methods will be used to simulate the use environment of the clean room and test the dust generation of the mop. The testing equipment will capture the number and size of fibers shed by the mop under certain time and certain actions. Only mops that meet strict standards can enter the clean room for use. At the same time, aging tests will be carried out to simulate the state of the mop after long-term use and detect its fiber shedding under wear and tear to ensure that the mop can meet the cleanliness requirements of the clean room throughout its service life.
In addition to the above main design points, there are some auxiliary designs that can also effectively avoid fiber shedding pollution. For example, an anti-slip and anti-static grip area is designed on the mop rod to prevent the operator from applying improper force to the mop due to hand slip during use, resulting in fiber shedding. In addition, the mop is treated with anti-static treatment as a whole to prevent dust and fibers from being adsorbed by static electricity and reduce the possibility of secondary pollution. Through these all-round and multi-level designs, the clean room mop can minimize fiber shedding and maintain the clean environment of the clean room.
