Operations takeaway: TX1009 is most effective when it is treated as part of your ISO 14644 operations control program—defined wipe technique, defined wetness (damp-film vs. wet), defined change-out triggers, and controlled introduction/storage to prevent “clean wipes” from becoming a contamination source.

Control point: Most “wiper failures” are technique failures—over-wetting, re-wiping with a loaded face, backtracking into clean areas, or using a wiper beyond its change-out point.

• Product: Texwipe AlphaWipe® TX1009
• Size: 9" x 9" nominal (23 cm x 23 cm)
• Material / structure: 100% continuous-filament polyester; double-knit, no-run interlock pattern
• Edge construction: Laundered cut edge (cut-edge knit processed for cleanroom use)
• Processing: Cleanroom laundered and packaged; solvent-safe packaging; lot-to-lot traceability
• Cleanroom use positioning: Commonly used across ISO Class 4–8 (confirm final suitability to your process and method)
• Packaging: 150 wipers/bag (2 inner bags of 75); 10 bags/case; 1,500 wipers/case
• Temperature note: Manufacturer guidance commonly references use below 400°F (205°C) (verify for your process and chemistry)

Documentation rule: For controlled/validated programs, always base acceptance criteria on current manufacturer documentation and lot records (not web summaries).

• Ions (typical): Sodium 0.22 ppm; Potassium 0.06 ppm; Chloride 0.05 ppm
• Test methods: Per ITW Texwipe published methods (see datasheet for TM references and program notes)

• General wiping of work surfaces, equipment, and parts in controlled environments
• Spill control where high sorbency and controlled pickup reduce spread and redeposit
• Applying and removing lubricants, adhesives, residues, and other process solutions
• Solvent wiping with common cleanroom chemistries (e.g., IPA; confirm compatibility to your SOP)
• Polishing/cleaning stainless steel and other durable substrates
• Lining trays to protect, dry, stage, or store parts and devices
• Protective covering for parts and product during transfer/staging (when allowed by your contamination controls)

Abrasion-resistant intent: Manufacturer guidance positions TX1009 for use on more abrasive surfaces where wipes that snag or abrade can become a particle source.

1. Control introduction: bring wipes into the cleanroom per your OCP rules (outer packaging removal, staging, and storage).
2. Use clean-to-less-clean flow: wipe from the cleanest zone to the dirtiest zone; do not backtrack.
3. Fold for control: fold to create multiple clean faces. Use one face per pass, then refold—do not “scrub forever” with a loaded surface.
4. Damp-film technique: if using solvent, wet the wiper to a controlled damp state (not dripping). Over-wetting is a primary cause of streaks/tide marks and redeposit.
5. Straight-line strokes: use consistent pressure and unidirectional strokes; avoid circular scrubbing that redistributes contamination.
6. Change-out triggers: replace when the wipe loads, smears, becomes tacky, or when the surface quality standard is at risk.
7. Dispose correctly: discard used wipers immediately into the designated waste stream (do not stage used wipes on benches/carts).

Method standardization tip: If outcomes differ by operator, lock four variables in the SOP: wetness target, stroke count, fold pattern, and change-out point.

• If sterility is required: do not substitute a non-sterile wipe. Use the designated sterile AlphaWipe® variant required by your workflow and transfer rules.
• If ultra-low residues are gating: confirm NVR/ionic requirements against the current datasheet and your internal limits; use the appropriate validated wipe/grade if your limits are tighter than the typical values.
• If the surface is easily scratched: validate on delicate coatings/optical finishes; use a validated low-risk method and avoid excessive pressure.
• If the chemistry is aggressive: verify compatibility and safety for your solvents/cleaners; do not assume universal compatibility.
• If you need pre-wetted control: consider pre-wetted AlphaWipe® options (e.g., 70% IPA) when process discipline requires fixed solvent loading.

Why this matters: Wipers and gloves function as a system. Using a cleanroom-grade wipe with a non-cleanroom glove introduces particles, fibers, and ionic contamination that can negate the benefit of low-lint polyester construction and controlled wiping methods.

Glove discipline: Change gloves when contaminated, solvent-wet, torn, or after contacting non-controlled surfaces. Treat gloves as a primary contamination vector during wiping operations.
