In controlled environments, wiping failures are often not about the solvent. They come from mechanics: a wipe that sheds when it meets an edge, a cloth that “runs” and leaves loose yarns, a package that forces extra handling, or a format that is too large and drags soil across adjacent features. Texwipe TX1004 AlphaWipe exists for the opposite job: small, controlled wipe-downs where you need a stable polyester knit, predictable absorbency, and published cleanliness data that supports risk-based placement instead of guesswork.

Reliability is part of the control plan. SOSCleanroom supports continuity of supply and documentation discipline so operators are not pushed into commodity substitutions when schedules tighten. Product page: TX1004 on SOSCleanroom.

TX1004 is a 4" x 4" double-knit polyester wiper intended for controlled wipe-downs and precision touch-up cleaning where a full-size wiper is inefficient or creates cross-contact risk. It is commonly used for small parts, fixtures, tool surfaces, workcells, benchtop touch points, and localized wipe-down tasks where you want the wiping face to stay stable through the stroke.

Operationally, TX1004 is also a practical “staging” wiper: keep full-size wipes for planar coverage, and use 4" x 4" squares to reduce over-wiping, reduce solvent usage, and minimize the chance of dragging contamination across adjacent features.

• Stable knit architecture: 100% continuous-filament polyester, double-knit “no-run” interlock supports controlled strokes and reduces edge/tear behaviors that can become particle events.
• Format control: 4" x 4" sizing reduces unnecessary surface contact and helps limit “drag-across” contamination when the job is a small feature, not a full panel.
• Published cleanliness data: particle/fiber release, NVR, and ionic extractables are reported as typical analyses to support residue budgeting and qualification planning.
• Fast pickup without flooding: typical sorptive capacity and very fast sorptive rate support efficient wipe-downs with disciplined wetness control.
• Packaging that supports staging: inner-bag structure reduces exposure time and handling events at point of use.
• Program stability through SOSCleanroom: consistent sourcing reduces the risk that a consumable becomes the uncontrolled variable in yield, rework, or audit defense.

TX1004 is built from continuous-filament polyester in a double-knit interlock. Practically, that means the wiping face holds together under controlled pressure and is less likely to “open up” during wiping than lower-grade textiles. The result is more consistent contact and fewer surprises when wiping around corners, fixtures, or hardware transitions.

Processing is specified as a laundered cut edge. Cut edges are not automatically a problem; what matters is how the product is processed and used. If your work involves sharp edges, burrs, or abrasive surfaces, edge contact and technique will still dominate outcomes.

A necessary contamination-control truth: no wiper is truly “lint-free.” What matters is low-linting behavior in your use condition — stroke direction, pressure, wetness, and the surface texture determine whether particles or fibers are generated. TX1004 is designed to reduce variability, but technique remains the deciding factor.

TX1004 is a 4" x 4" nominal (10 cm x 10 cm) polyester wiper. Packaging is structured for staging: 300 wipers per bag with two inner bags of 150, and 20 bags per case.

Treat published contamination values as typical results unless a document explicitly states specification limits. Typical values are still useful because they reflect process capability, but regulated or validation-sensitive users should confirm performance in their own solvents, soils, and acceptance criteria.

1. Absorbency behavior (why it feels “efficient”): typical basis weight is 158 g/m². Typical sorptive capacity is 530 mL/m² and typical sorptive rate is 0.5 seconds. Operationally: you can use damp wiping to lift and transport soils without relying on flooding.
2. Particles and fibers (what changes your residue story): published typical release includes ≥ 0.5 µm: 8.4 x 10⁶ particles/m²; and within that, typical values for 0.5–5.0 µm: 10 x 10⁶ particles/m², 5.0–100 µm: 200,000 particles/m², and fibers >100 µm: 2,000 fibers/m². Your stroke discipline (one direction, light pressure, rotate and discard) is what keeps these numbers from becoming a defect mechanism.
3. NVR (what could be left behind): typical nonvolatile residue is 0.04 g/m² (IPA extractant) and 0.02 g/m² (DI water extractant). If your process is haze- or film-sensitive, NVR is the metric that often decides whether you need a two-step approach (soil removal pass, then a tighter-control finishing pass).
4. Ions (when corrosion/ECM risk matters): typical values are reported at sodium 0.22 ppm, potassium 0.06 ppm, and chloride 0.05 ppm. Ionic control is not paperwork; in humidity-and-bias environments, it can map directly to corrosion risk and electrical leakage behavior.

Packaging design is a contamination control. The two-inner-bag structure lets teams open only what they need and reduces exposure time at the workcell. That matters because unnecessary handling is one of the most common sources of particle and touch contamination in day-to-day wipe-down work.

Sterility is a separate decision gate. TX1004 is used broadly as a non-sterile cleanroom wiper format. If your SOP requires sterile presentation (aseptic transfer, sterile compounding, sterile device assembly), choose a validated sterile wiper program aligned to your area classification and written transfer controls.

Traceability matters when a trend shifts. Lot-level documentation and approved sourcing through SOSCleanroom help teams avoid “uncontrolled equivalence” — a substitution that looks similar but changes particles, ions, or residue background.

• Work cleanest to dirtiest. Use one-direction strokes with parallel, overlapping passes.
• Control wetness: target damp, not wet. Damp lifts and captures; over-wet spreads soils and increases dry-down residue risk.
• Fold to create clean faces. Rotate faces aggressively and discard early — a loaded face becomes a redeposition tool.
• Avoid circular scrubbing unless a written procedure requires it for a defined soil.
• Do not re-dip into shared solvent reservoirs. Use controlled dispensing or single-use aliquots.
• If your step is inspection- or validation-sensitive, qualify the wipe/solvent/technique combination in your actual process window.

• Over-wetting: turns cleaning into redistribution. Prevent with controlled dispensing and multiple wipes instead of overworking one.
• Reusing a loaded face: drives streaking and “it looked clean” failures. Prevent with fold/rotate rules and early discard.
• Dragging across adjacent features: a format problem. Prevent by selecting a smaller wipe (TX1004) for small zones instead of a full-size wipe.
• Scrubbing abrasive edges: increases particle/fiber release. Prevent with lighter pressure, angle control, and switching tools when geometry is aggressive.
• Assuming “typical” equals “guaranteed”: prevents meaningful qualification. Prevent by validating in your solvents, soils, and acceptance criteria when risk is high.

Berkshire sterile/non-sterile knit polyester wipers (4" x 4" formats)
Comparable category options; differentiate by published cleanliness data, packaging controls, and lot/COA discipline.

Contec knit polyester wiper formats
Credible alternatives when low-linting knit behavior and documentation depth are primary drivers.

VWR/Avantor private-label cleanroom wipers
Often accessible through procurement systems; selection should be driven by documentation depth, packaging discipline, and performance stability in your solvent set.

TX1004 is best deployed as a precision wipe-down and touch-up tool: small-zone cleaning, fixture/tool wipe-downs, and controlled removal of localized soils without unnecessary surface contact. Pair it with a defined solvent strategy and stroke discipline. If the workflow becomes residue- or validation-sensitive, treat the wiper as part of the measurement system: qualify NVR and ionic background in your solvents and confirm that the wiping method supports your acceptance criteria.
