TX8944 TexVantage 4" x 4" sealed-edge polyester wiper: abrasion-ready small format for controlled wipe-downs
Last reviewed: Jan. 4, 2026 | Audience: contamination control, cleanroom operations, EHS, quality
TX8944 TexVantage is a dry, sealed-edge, 100% polyester cleanroom wiper designed for spill control, cleaning, and solution application where edge integrity matters. The 4" x 4" format is commonly selected for tight work zones (fixtures, tooling, corners, small panels) where a larger wipe becomes awkward and encourages re-contact.
In a wiping program, TX8944 is best understood as a “high-contact control wipe”: small, durable, and chemically compatible, with a sealed-edge strategy intended to reduce fraying and edge-shed when surfaces are more abrasive or have sharp features. Typical contamination metrics from Texwipe testing provide a starting point for qualification, not a substitute for your process validation.
What it’s for
Controlled wipe-downs of work surfaces, equipment, and parts; spot cleaning and spill pickup; and applying/removing solvents, disinfectants, lubricants, and residues when you need a sealed edge for better durability on higher-friction features. Common use cases include benches and carts, tool wipe-downs, fixtures, machine guarding, and “touch-point” cleaning where repeat strokes occur.
Decision drivers
Select TX8944 when the main risk is not “coverage per wipe,” but edge durability, access, and consistent wipe mechanics on smaller targets.
- Sealed-edge durability: Helps maintain edge integrity during repeated strokes on abrasive or sharp-featured surfaces, reducing fray-driven shedding risk.
- Small-format control: 4" x 4" supports disciplined wipe patterns (single-pass, controlled overlap) in confined areas and reduces accidental re-contact of a “dirty” zone.
- Chemical compatibility: Polyester is widely used with IPA, ethanol, acetone, and degreasers; confirm compatibility with your specific chemistry and surface materials.
- Contamination starting point: Typical particles/fibers, NVR, and ionic residues inform qualification and change-control discussions (they are not product specifications).
- Packaging + traceability: Lot coding and inner-bag strategy support controlled dispensing, segregation by line/area, and audit readiness.
Materials and construction
TX8944 is constructed from 100% polyester with a sealed edge. In practical terms, the sealed edge is the control feature: it is intended to prevent the cut perimeter from unraveling or “feathering” under friction, which is a common pathway for edge-generated debris during aggressive wiping.
The polyester substrate also tends to tolerate a broad range of common cleanroom solvents. That matters when wipe-downs shift between wet cleaning (to dissolve and lift residues) and dry finishing passes (to remove remaining solvent film without leaving fibers behind).
Specifications in context
Size: 4" x 4" (10 cm x 10 cm) nominal. Edge: sealed edge. Material: 100% polyester. Packaging: 300 wipers/bag (2 inner bags of 150); 20 bags/case. The inner-bag format is useful operationally: it reduces repeated exposure of the full case quantity and supports “one inner bag per line/shift/area” controls when needed. Typical physical characteristics reported by Texwipe for the TexVantage Polyester family include a basis weight of 120 g/m², sorptive capacity of 330 mL/m², and a sorptive rate of ~0.5 seconds—helpful when you are balancing pickup speed against residue control.
Cleanliness and performance metrics
For qualification discussions, break the metrics into three buckets: (1) particles/fibers released during wiping, (2) nonvolatile residue (NVR) that can dry down as a film, and (3) ionic residues that can matter for sensitive electronics and certain surface chemistries. “Typical” values are a starting point—expect your actual results to depend on solvent system, surface roughness, contact pressure, and wipe technique.
Texwipe’s published typicals for TexVantage Polyester include (family-level testing): LPC ≥0.5 µm on the order of 12 x 106 particles/m² and fibers >100 µm around 800 fibers/m²; NVR on the order of 0.06 g/m² (IPA extractant) and 0.02 g/m² (DI water extractant); and ions reported in ppm for sodium, potassium, and chloride. Treat these as comparative signals when selecting between polyester sealed-edge options and higher-absorbency blends.
Packaging, traceability, and lot control
TX8944 is packaged as 300 wipers per bag with two inner bags of 150, and is described by the manufacturer as individually lot coded for traceability and quality control. In regulated or audit-sensitive programs, this supports segregation by area (ISO zone), equipment family, or campaign—especially when a deviation triggers “what lots were used where” questions.
Rule of thumb: If you cannot trace a wipe lot to a cleaning record, treat the cleaning event as “not fully documentable.” Keep outer bags in the receiving quarantine area; only inner bags enter the controlled zone.
Best-practice use
TX8944 performs best when the wipe technique prevents re-deposition and limits “over-scrubbing” that can drive frictional shedding on rough features.
- Fold to create clean faces: Quarter-fold (or smaller) so you can rotate to a fresh face frequently; do not “wipe until it feels dry” on critical surfaces.
- One-direction strokes with overlap: Use single-pass strokes and a consistent overlap (think: mowing a lawn). Avoid circular wiping unless you are intentionally emulsifying a stubborn residue and will follow with a controlled finishing pass.
- Wet-clean, then dry-finish: Dissolve and lift residues with a wet pass, then use a fresh wipe/face for the final dry pass to prevent leaving a solvent film or streaking.
- Pressure discipline: Use only the contact force needed to maintain full surface contact; excessive pressure increases friction and can raise particle release on rough fixtures.
- Point-of-use control: Dispense from the inner bag only; reseal or recontain to reduce exposure and accidental contact contamination.
Common failure modes
The most common program failures are technique-driven: re-deposition from overusing a single wipe face, “polishing” a dissolved residue into a thin film by wiping while it is drying, and snag events on sharp features that can create localized debris. Prevent these by enforcing face-rotation rules, using a wet-to-dry sequence, and switching to a fresh wipe immediately after any snag or edge damage. If a surface is rough enough to repeatedly catch a wipe, treat the surface condition as a maintenance issue—not a wiping problem.
Closest competitors
Berkshire MicroSeal® 1200 (ultrasonically sealed, 100% polyester knit): Typically positioned for ISO Class 3+ environments and emphasizes high absorbency plus sealed-edge durability. Knit construction can feel more “cloth-like” than some polyester wipes and may be preferred for certain critical wipe-downs, but your residue profile and surface friction will determine which performs better in practice.
Valutek laser-sealed polyester wipers (laser-sealed edge, double-knit interlock): Often targeted at ISO 3–4 / Class 1–10 programs with an emphasis on very low particulate and extractables. If your specification is driven by the tightest cleanliness targets rather than general-purpose wipe-downs, laser-sealed knit options are common alternatives.
Contec Polynit Heatseal wipes (sealed edges, knit polyester): Another sealed-edge knit polyester approach, typically marketed around very low particles/fibers and chemical resistance. These are often considered when teams want a sealed-edge knit fabric and are comparing “edge technology + knit pattern” as the main performance levers.
Where it fits in a cleanroom wiping program
TX8944 fits as a small-format sealed-edge polyester wiper for day-to-day controlled wipe-downs, spot cleaning, and higher-contact cleaning of fixtures and tools—especially where sharp edges, fasteners, and rough surfaces make edge durability a deciding factor. If your program shifts toward more critical product-contact surfaces or higher sensitivity to ions/NVR, escalate by qualification results: tighten wipe-face change rules, consider alternative polyester sealed-edge knit constructions, or step into higher-cleanliness tiers as your risk assessment requires.
Terminology note: Engineered for low-linting performance; no wiper is truly “lint-free” in every process condition.
