Texwipe TX701 Large Paddle Head Alpha® Polyester Knit Cleanroom Swab (Extra-Large Swab, Thermal Bond, Silicone-Free/Amide-Free Bag)

Texwipe TX701 is an extra-large, paddle-head Alpha® polyester knit cleanroom swab built for critical cleaning and controlled solution application/removal when a standard swab does not provide enough contact area per pass. The double-layer 100% polyester knit head increases absorbency and mechanical pickup for thin films, light residues, and particulate on broader flats, tooling faces, fixture lands, wide slots, and gently contoured surfaces. A complete thermal bond construction eliminates adhesive at the head/handle interface (a common source of residue variability in solvent work), and the virgin polypropylene handle provides chemical resistance and clean handling. TX701 is cleanroom laundered for ultra-low background contribution and is supplied lot coded in a silicone-free and amide-free bag to support contamination investigations, process standardization, and repeatable line-side execution. Low-linting performance is process-dependent (no swab is truly ‘lint-free’ in every surface condition and technique).

Texwipe (an ITW company) builds cleanroom swabs as engineered contamination-control tools—controlling substrate selection, laundering/cleanroom processing, thermal bonding (to eliminate adhesive contamination), and packaging chemistry aligned to critical cleaning realities. For Alpha® polyester knit swabs like TX701, the design intent is repeatability: consistent geometry, controlled absorbency, low background contribution (particles, ions, and non-volatile residue), and packaging discipline that supports line-side standardization.

SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship focused on continuity of supply, practical product selection support, and documentation-forward handling—so customers can keep validated cleaning steps stable over time and avoid uncontrolled substitutions that change process behavior.

• Extra-large paddle head increases contact area for faster coverage per pass on flats, fixture lands, and tooling faces
• Double-layer polyester knit head for enhanced absorbency and controlled wipe feel
• Engineered to resist snagging and abrading to help reduce particle/fiber release in practical use
• Complete thermal bond construction (no adhesive) to reduce bond-line residue variability in solvent cleaning
• 100% virgin polypropylene handle for chemical resistance and clean handling
• Cleanroom laundered for ultra-low levels of particles, typical ions, and typical NVR (method-dependent)
• Lot coded for traceability and quality control (supports investigations and change control)
• Packaged in a silicone-free and amide-free bag to reduce common transfer risks in film-sensitive work
• Autoclave safe in dry heat and steam (confirm your validated cycle)

• More area cleaned per stroke: Paddle-head geometry reduces the number of passes needed to achieve a clean result, supporting single-direction wipe discipline
• Cleaner solvent performance pathway: Adhesive-free thermal bonding helps prevent hidden residue sources at the head/shaft interface during IPA and other compatible solvent work
• Residue visibility control: Typical NVR is commonly reviewed for film-sensitive cleaning; TX701 typical NVR is 0.01 mg/swab (DI water extractant) and 0.03 mg/swab (IPA extractant) (typicals; method-dependent)
• Ionic background awareness: Typical ionic values are reported as very low (example typials include sodium 0.16 µg/swab, chloride 0.12 µg/swab, sulfate 0.11 µg/swab), supporting applications where salts can drive haze, corrosion, or measurement noise
• Packaging chemistry confidence: Silicone-free and amide-free bagging supports coating, optics, and surface-finish workflows sensitive to transfer contaminants
• Traceability for investigations: Lot coding supports faster containment and root-cause separation when inspection shifts flag residue or fiber changes

• Precision spot cleaning of grooves, tracks, slots, channels, and other small spaces that still benefit from a broader contact patch
• Cleaning broader flats: tooling faces, fixture lands, platen surfaces, gasket lands, and wide slots where a standard swab is inefficient
• Applying and removing lubricants, adhesives, and process solutions in a critical clean environment
• Solvent cleaning and wipe-down (IPA is common; verify compatibility to your chemistry and SOP)
• Maintenance and inspection cleaning where low background contribution and repeatable technique matter

• Think “paddle wipe,” not “swab scrub”: Align the long axis of the paddle with your stroke direction so the face stays flat and pressure stays distributed.
• One-direction strokes with overlap: Use parallel, overlapping passes. Avoid circular scrubbing unless your written procedure explicitly requires it.
• Wetness control: Damp lifts; over-wet spreads. Over-wetting increases pooling and can create dry-down rings or end-of-stroke residue lines.
• Single-pass discipline with face rotation: Rotate the paddle face frequently. Do not rework the same area with a loaded face.
• No re-dipping: Do not return a used swab into your solvent reservoir. Decant into a small working vessel and replace it frequently to prevent cross-contamination.
• Pressure control near edges: Burrs and sharp features can snag any knit. Reduce pressure near edges, adjust stroke direction, and deburr hardware where feasible.
• Standards awareness: Align classification, documentation, and cleaning verification expectations to your program (ISO: https://www.iso.org/standard/53394.html; FDA: https://www.fda.gov; ASTM: https://www.astm.org; IEST: https://www.iest.org).

• Choose TX701 when coverage per pass is the constraint: The extra-large paddle head is built for broader flats and wider wipe zones where smaller swabs increase stroke count and variability.
• Polyester knit vs. foam: Polyester knit is often preferred where snag resistance, low-linting behavior, and solvent versatility are primary drivers; foam may be preferred for different fluid-hold or “soft contact” behavior on certain geometries. Match head material to soil type, surface finish, and inspection method.
• Non-sterile vs. sterile: TX701 is non-sterile. If your introduction protocol or critical zone requires sterile packaging controls, specify a sterile Alpha® swab configuration aligned to your SOP.
• Packaging discipline matters: Use the inner 25-count bags as point-of-use packs to reduce repeated bag opening at the bench and to stabilize contamination direction control.
