BN.11050209 is a narrow-width lint-free roll cloth designed for precision cleaning in confined spaces. Constructed from 105g ultra-fine fiber twill, this product delivers excellent particle capture capability with a 10mm width that reaches tight areas.
The 50m length and compact 115mm outer diameter make this model ideal for applications with limited space or where frequent changeover is required. The standard 25.4mm (1 inch) core ensures compatibility with most roll holders.


Our clients from semiconductor, pharmaceutical, medical device, and aerospace industries trust our cleanroom wipers for consistent performance, high absorption, and low particle generation. Here’s what they have to say.

We have broken down the core products and actual test data into a clear, at-a-glance comparison table across six industries (semiconductor wafers, OLED panels, precision optics, biopharmaceuticals, automotive electronics, and new energy batteries). The table includes the wiper or cleanroom consumable model for each industry, key physical parameters (particle shedding, water absorbency, ionic residues, etc.), and applicable compliance standards (SEMI, GMP, IATF 16949, ISO 10993, etc.)
