<p>A lint-free wiper formed of an edge of cloth which does not contain in its structure a sectional surface of a cloth edge that may otherwise constitute a dust making source such as lint and separated fiber, whereby the wiper can be used reliably in a clean room of a high cleanliness level of not higher than class 100 with dust making significantly suppressed. Since a dust suppressing function is based on a cloth edge structure featuring an edge side formed in a loop, the wiper can be prepared without requiring welding nor bonding on a cloth sectional surface and therefore the lint-free wiper is virtually not restricted by material such as non-thermoplastic cellulose fiber.</p> |
