equipment cleaning, hardware plating, mold cleaning, electronic product cleaning, etc. B. Sub-fine dust-free cloth is suitable
for: printer nozzles, digital inkjet paintings, ordinary lenses, touch screens, LCD screens, glossy panels, etc. C. Ultra-fine
dust-free cloth is suitable for: precision instruments, high-end optics, polished electroplating measuring instruments, auto
parts, cameras and glasses, etc. Q2. What material is the dust-free cloth made of? What is the difference between general energy and ultrafine? A.Basic weight:
Whether the basis weight of the same kind of fabric is the same B. Type and quality: Microfiber is of higher quality, sub-fine
fiber is second, and polyester fiber is lower. Choose the appropriate one according to your needs. C. Softness: The softer, the
better D. Wear resistance: The stronger it is, the less likely it is to lose fiber. E. When purchasing a product, the first thing

Q3. What are the differences in the amount of dust generated by different edge sealing methods: Dust-free cloth can be divided
into: thermal cutting, ultrasonic cutting, laser cutting and general cold cutting according to the edge sealing method:
A. Ultrasonic cutting: The edge sealing degree reaches 99%, the edge sealing is soft and even, not easy to tear, does not shed
chips, and has no dust. The technology and cost are relatively high.
B. Laser cutting: The edge sealing degree is less than 80%, and no chips are shed. After cleaning, the edge sealing is easy to
tear and chips are shed.
C. Thermal cutting: The edge sealing degree is less than 75%, and no chipping occurs. After cleaning, the edge sealing is easy to
tear and chipping.
D. General cold cutting: no edge sealing, easier to chip, lower technology and cost.
