Texwipe TX743B Small Alpha Polyester Cleanroom Swab (Knitted Polyester, Thermally Bonded)

Texwipe TX743B is a small-format Alpha® polyester knit cleanroom swab engineered for precision cleaning in grooves, tracks, slots, and other tight geometry where wipes cannot maintain a stable contact face. It uses a double-layer knitted polyester head that is thermally bonded (no adhesive) to a virgin polypropylene handle for repeatable tip integrity, low-linting performance (no swab is truly ‘lint-free’ in every process condition), and compatibility with common cleanroom solvents such as IPA. Each bag is lot coded for traceability and packaged in a silicone-free and amide-free bag to support contamination-control workflows across ISO-class cleanrooms and controlled environments.

Texwipe (an ITW company) differentiates itself in cleanroom swabbing by treating the swab as an engineered contamination-control tool, not a commodity. For knitted polyester swabs, that means controlled materials, automated forming for consistent geometry, thermal bonding to remove adhesive as a residue variable, and packaging designed to reduce silicone/amide risk while supporting lot traceability.

SOSCleanroom (SOS) supports that documentation discipline and product consistency through a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (lot traceability and certificates when applicable), and practical application support—so customers can standardize swab materials with predictable performance while maintaining procurement reliability and audit readiness.

• Double layer of knitted polyester fabric for enhanced absorbency
• Thermal bond construction eliminates adhesive contamination at the bond line
• Engineered to resist snagging and abrading to help reduce particle and fiber release (process-dependent)
• Excellent chemical resistance for compatibility with a variety of cleanroom solutions (verify compatibility to your chemistry and SOP)
• 100% virgin polypropylene handle helps reduce the risk of introducing additional contaminants
• Cleanroom laundered and manufactured for ultra-low particles, ions, and NVR (typical values published)
• Autoclave safe in dry heat and steam (process-dependent)
• Lot coded for traceability and quality control
• Packaged in a silicone-free and amide-free bag
• Identification/traceability cue: Texwipe CleanTips® use trademarked light-green/green handles (e.g., Reg. No. 5,343,973) with “TEXWIPE” embossed on the handle for line-side identification and substitution control

• Precision control in tight geometry: Small head and rigid-core design help maintain consistent pressure and contact in grooves, slots, and corners
• Reduced residue variables: Adhesive-free thermal bonding helps reduce one common contributor to streaking, haze, or residue during solvent cleaning
• Low-linting performance: Knitted polyester is designed to resist snagging and shedding (note: no swab is truly “lint-free” in all conditions)
• Solvent compatibility: Polyester knit + polypropylene handle are commonly used with IPA and other cleanroom-compatible chemistries (verify with your SOP)
• Traceability and process stability: Lot coding and controlled packaging support receiving checks, investigations, and change control

• Precision spot cleaning of grooves, tracks, slots, recesses, and small interfaces
• Cleaning connector corners, ferrule shoulders, thread roots, seams, and tight wipe points
• Applying and removing lubricants, adhesives, coatings, and process solutions in critical environments
• Solvent cleaning (such as IPA) where controlled, repeatable swabbing is required
• Detail cleaning in microelectronics, semiconductor operations, optics/photonics handling, medical device assembly, pharma/biologics workflows, and other controlled environments

• Control wetness: Use a defined solvent volume (damp, not dripping) to lift and capture residues without pooling into corners or joints.
• Single-direction strokes: Use straight-line strokes; avoid scrubbing that can snag knit on sharp edges.
• Rotate and discard early: Rotate contact faces frequently; discard the swab once the head becomes visibly loaded or begins to streak.
• Avoid cross-contamination: Do not re-dip into shared solvent reservoirs; use controlled dispensing or aliquots to reduce carryback risk.
• Match tool to geometry: Use the smallest swab that maintains stable contact without bending, collapsing, or pushing soil deeper into seams.

• Knitted polyester vs. foam: Choose knitted polyester when you need durability, controlled geometry, and strong solvent compatibility; choose foam when a softer conforming face is needed for broader contact (verify residue/particle risk to your application).
• Small geometry fit: TX743B is designed for small spaces; for even tighter features, consider a smaller “micro” geometry; for more coverage per stroke, step up in head size (match swab size to feature size and risk).
• Cleaning vs. regulated sampling: If the task is compliance-driven cleaning validation sampling (rather than cleaning), use a validated sampling method and sampling-appropriate tools; align expectations to your quality system and applicable guidance (ISO cleanroom classification context: iso.org/standard/53394.html; regulatory and method context: fda.gov, astm.org, iest.org).
