TX7031 is a long-format AlphaSat® polyester wiper that also functions as a mop cover, pre-wetted with a 0.2 µm filtered 6% IPA / 94% DI water blend to standardize wetness and reduce operator-dependent variability. For many facilities, the real win is not “more alcohol” — it is process control: consistent wet-out, consistent wipe feel, and repeatable surface coverage when you are cleaning larger panels, benches, stainless, carts, or pass-through interiors.

From a contamination-control standpoint, TX7031 sits in a practical middle ground: a cleanroom-laundered, continuous-filament, double-knit polyester substrate with a cut edge, paired with a low-IPA, DI-water-dominant chemistry that supports particulate pickup while moderating evaporation, odor, and rapid dry-down. Used correctly, it is a strong “standard work” consumable for routine wipe-downs, spill response, and controlled mopping where you want repeatable wetness without the variability of open buckets or hand-mixing.

Routine cleaning and spill control on large surfaces in cleanrooms and controlled environments using a controlled 6% IPA / 94% DI water pre-wet. Typical use cases include benches, stainless panels, carts, pass-throughs, gowning fixtures, equipment covers, and mopping-style wipe-downs where a 9" x 32" format improves reach and reduces changeouts.

Select TX7031 when your cleaning goal is repeatability: consistent wetness, predictable residue behavior, and reliable contamination control on larger surfaces.

• Wetness control: 0.2 µm filtered 6% IPA / 94% DI water supports consistent wet-out and coverage without hand-mixing variability.
• Residue and VOC management: Lower IPA concentration reduces rapid flash-off and odor while still supporting wipe-down intent; validate residue acceptability for your process surfaces.
• Format efficiency: 9" x 32" improves reach for panels and mop-style passes; fewer seams and fewer “wipe starts” can reduce re-deposition risk.
• Substrate integrity: Continuous-filament, double-knit polyester is designed to resist abrasion and shedding during rigorous use; cut-edge strategy is supported by cleanroom laundering and knit structure.
• Cleanroom compatibility: Broad compatibility across ISO-classified environments (confirm your room classification and task criticality).
• EHS and flammability controls: Pre-wetted IPA wipes still require ignition-source controls, glove/eye protection expectations, and compliant waste handling.
• Documentation discipline: Lot coding and controlled packaging support investigations, deviations, and audit readiness when wipers are treated as controlled consumables.

TX7031 uses an AlphaWipe®/AlphaSat® family substrate: 100% polyester, continuous-filament, double-knit construction that is cleanroom laundered and packaged. Continuous filament helps reduce fiber breakage compared with staple fibers, while the knit structure supports sorption and abrasion resistance for rigorous wipe-downs.

The edge strategy is listed as a cut edge. In practice, cut-edge performance is strongly influenced by laundering, knit stability, and how the operator uses the wipe (pressure, directionality, and how long the wipe is overworked). For abrasion-prone tasks, use controlled pressure and change wipes before they “go dry and grabby.”

Size: 9" x 32" (long-format wipe/mop cover). Wiper family: AlphaSat®. Material: Polyester. Edge: Cut edge. Cleanroom range (listed): ISO 4 (Class 10) to ISO 8 (Class 100,000). Case pack: 4 bags/case, 25 wipers per reclosable bag (100 wipers per case). The 9" x 32" format is most valuable when your SOP calls for long, straight passes (wipe-down “lanes”) or mop-style patterns where fewer wipe changes reduce handling and re-contact.

Cleanroom wiper “typicals” should be treated as a starting point for risk assessment and qualification — not as a blanket guarantee for every task. The most useful way to interpret metrics is by mechanism: particles/fibers (shedding), NVR (residue risk), and ions (surface/compatibility risk).

Typical contamination and performance (AlphaWipe®/AlphaSat® family): LPC (≥0.5 µm) 8.4 x 10⁶ particles/m²; fibers (>100 µm) 2,000 fibers/m². NVR (IPA extractant) 0.04–0.06 g/m²; NVR (DIW extractant) 0.01–0.02 g/m². Ions (typicals): sodium ~0.15–0.22 ppm, potassium ~0.03–0.06 ppm, chloride ~0.05–0.10 ppm. Physical typicals: sorptive capacity ~530 mL/m²; sorptive rate <0.3–0.5 seconds; basis weight ~158 g/m². For TX7031 specifically, the pre-wet is identified as 6% IPA / 94% DI water and filled using semiconductor-grade IPA for the 9" x 32" format.

TX7031 is packaged for operational control: reclosable packaging intended to slow evaporation and preserve consistent wetness across the bag, along with lot-to-lot traceability for quality control and investigations. In controlled environments, those two features reduce the chance that “the wipe itself” becomes the variable (dry-out, inconsistent saturation, or unidentified lots).

Good wiping is about controlling re-contact. Your goal is to pick up contamination and keep it in the wipe, not smear it across the surface.

• Fold and present clean faces: Fold the 9" x 32" wipe into manageable sections; rotate to a clean face after each lane or panel segment to prevent redeposition.
• One-direction passes: Wipe in straight, overlapping lanes (10–20% overlap). Avoid circular scrubbing unless your SOP requires it for a defined reason.
• Pressure discipline: Use controlled, moderate pressure. Excess force can increase mechanical shedding risk and can push soils into microtexture on sensitive finishes.
• Mop-cover mode: If used as a cover, use an “S-pattern” with consistent overlap, then step back and “close out” with a final straight pass. Replace the cover when visibly loaded or when drag increases.
• Chemistry segregation: Do not mix presaturated wipes with other chemistries in the same task unless your SOP explicitly allows it (incompatibilities can create residues or reduce cleaning efficacy).
• EHS controls: Even at 6% IPA, treat as a flammability-managed consumable: keep away from ignition sources and dispose per your facility waste stream controls.

The most common failure mode with presaturated wipes is overworking a wipe as it dries — drag increases, pickup efficiency drops, and soils can redeposit as streaks. Other frequent issues include leaving bags partially open (evaporation and wetness drift), using the wipe on incompatible or highly sensitive coatings without prior validation, and “double-dipping” behavior (re-contacting a cleaned area with a loaded wipe). Prevent these by enforcing clean-face rotation, lane discipline, and clear changeout triggers in the SOP.

Contec presaturated polyester wipes (large-format equivalents): Similar “process-control” logic (presaturated formats reduce wet-out variability). Compare on solution filtration/grade, packaging closure design, available formats, and validation documentation for your industry.

Berkshire presaturated cleanroom wipers: Often comparable for general wipe-downs. Differences typically show up in substrate knit behavior under abrasion, residue profiles, and how consistently wetness is maintained across time-in-use. For regulated programs, compare available certificates/lot traceability support and how your site qualifies wipe performance on target surfaces.

TX7031 is a strong candidate for routine, repeatable wipe-down and mop-style coverage on larger surfaces in ISO-classified environments where consistent wetness is valued. It can serve as a default consumable for benches and stainless wipe-downs, cart and fixture cleaning, and controlled spill response, especially when your program emphasizes reduced variability versus open-container wetting. For high-criticality surfaces, qualify wipe-and-dry behavior (streaking/residue) and confirm that the 6% IPA / DI water blend aligns with your residue and compatibility requirements.
