How to choose cleanroom wiper for electronic screen industry?

Electronic screen industry on the cleanliness of the dust-free cloth, abrasion resistance, liquid absorption and other requirements are extremely high, the choice should focus on the following core elements: 1. Material selection – ultrafine fiber: preferred 70% polyester + 30% nylon blended material, fiber diameter is fine (usually ≤ 0.1 denier), can effectively capture the tiny dust, and liquid absorption, do not fall off the chip, suitable for screen Cleaning and wiping. – Avoid natural fibers, such as cotton, which is easy to drop flakes, poor moisture absorption, and may retain impurities, affecting screen cleanliness. 2. Cleanliness level – according to the cleanliness level of the screen production environment (such as Class 10, Class 100) to choose the corresponding level of clean cloth, should be through the laser edge sealing and other processes to reduce fiber shedding, and after rigorous cleaning (such as 18MΩ deionized water cleaning), to ensure that there is no residual contaminants (such as particles, ions, micro-organisms). 3. Size and Weave – Size: Choose according to the wiping scenario, e.g. small size (3×3 inches) for precision parts, large size (6×6 inches) for overall cleaning of the screen surface. – Weave: ◦ Plain: flat surface, suitable for general cleaning. ◦ Mesh: breathable, fast liquid absorption, suitable for removing water or oil stains. 4. Edge treatment – Prefer laser edge sealing or ultrasonic edge sealing to avoid fiber shedding caused by traditional needle and thread edge sealing and to reduce secondary pollution to the screen. 5. Liquid absorption and abrasion resistance – the requirements of the dust-free cloth high liquid absorption (can quickly absorb detergent or water), at the same time have a certain degree of abrasion resistance, not easy to break after repeated wiping, lint. 6. Compliance with industry standards – the need to comply with the relevant standards of the electronics industry (such as ISO 14644 clean room standards), to ensure that the number of particles of the cloth, the ion content (such as chlorine, sodium, etc.) to meet the requirements to avoid corrosion of the screen or to affect the display effect.
