About the Manufacturer:

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. Its manufacturing approach starts with fiber and fabric selection (here, continuous-filament nylon for a soft-but-strong knit), then controls construction (no-run interlock), cleanroom laundering/processing, and protective packaging aligned to contamination-control use cases—including Bag-Within-A-Bag® handling discipline and statistical quality control.

Texwipe also supports verification through contamination and extractables testing (particles/fibers, NVR, and ions are commonly reported as typical values in manufacturer literature) to help teams standardize wiping materials with predictable performance. SOSCleanroom (SOS) supports that documentation discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so customers can maintain procurement reliability and audit readiness while standardizing critical wiping steps.

TX4009 Features:

100% synthetic fiber — double-knit nylon
Continuous-filament, no-run interlock pattern
Cleanroom laundered and packaged
Solvent-safe Bag-Within-A-Bag® cleanroom packaging

TX4009 Benefits:

Strength and durability: Excellent tensile strength, elasticity, and durability for repeated folding and pressure wiping
Low-linting performance: Ultralow particulate generation and low extractable levels help reduce product and cleanroom contamination contribution (process-dependent)
Soft, nonabrasive surface: A strong option for sensitive optical and photomask surfaces where scratch risk is a control point
Fast uptake / high sorption (typical): Manufacturer literature reports rapid sorptive rate (<1 second) and strong sorptive capacity (typical 530 mL/m²)—useful for controlled spill pickup and wet wipe-down steps
Lot-to-lot traceability: Supports controlled-environment documentation expectations

Common Applications:

Superior for spill control and general wiping in critical environments
Cleaning and polishing metallic and nonmetallic magnetic media disk surfaces
Cleaning sensitive optical and photomask surfaces
Abrasive surface cleaning where a durable knit is preferred

Best-Practice Use:

Fold for control: Fold into quarters to create multiple clean faces; rotate faces instead of re-wiping with a loaded surface.
Wipe pattern: Use straight-line strokes (top-to-bottom or left-to-right) to reduce re-deposition—especially on optical and inspection-critical surfaces.
Pressure discipline: Let the knit do the work; use controlled, consistent pressure to avoid driving trapped particles across sensitive surfaces.
Wet vs. dry: For solvent wipe-downs, dampen—do not over-saturate—to maintain control and reduce dripping; verify chemical compatibility to your SOP.
Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins to leave streaks/residue—or after any contact with a suspect debris source.

Selection Notes (TX4009 vs. Other Options)

TX4009 vs. TX4004: Same MiracleWipe® nylon knit; TX4004 is the smaller 4" x 4" format typically used for tight spaces, small tools, and detail cleaning.
TX4009 vs. TX4012: Same MiracleWipe® nylon knit; TX4012 (10" x 12") is often chosen when coverage per wipe matters and you want fewer wipe changes on larger surfaces.
Nylon vs. polyester knits: Nylon is commonly selected when you want a soft-but-strong knit for optics/media use cases; polyester knits are often selected for broad chemical compatibility and general wipe-down standardization (verify based on your chemistry and surface sensitivity).

Nylon as a Process Control: Why TX4009 MiracleWipe Is the Right Knit for Smear-Sensitive Surfaces and High-Handling Cleanroom Wiping

Last reviewed: Jan. 2, 2026 | Audience: contamination control, cleanroom operations, optics/metrology, EHS, quality

Texwipe TX4009 MiracleWipe (9" × 9") is a dry, knitted 100% continuous-filament nylon cleanroom wiper built for a very specific reality: some “cleaning” failures are not chemistry failures — they are surface-interaction failures. Softness, smear behavior, and how a wipe releases or retains films can matter as much as particle and residue numbers, especially on optics, coated features, and media-like surfaces where the first visible defect shows up after dry-down.

TX4009 is positioned as an ultra-clean, nonabrasive nylon knit that is also moderately adsorbent and mechanically stable under handling. In controlled programs, it is most valuable when teams want a knit wiper that behaves predictably on sensitive surfaces, while still maintaining packaging discipline and lot traceability to reduce “untracked substitution” risk in audits and investigations.

What it’s for

TX4009 is typically selected for general wiping and spill control in controlled environments, plus the use-cases where surface gentleness and smear control are part of the acceptance criteria. Manufacturer positioning includes use on magnetic media disk surfaces, optics/photomask workflows, and cleaning tasks that may involve more contact events than a final-pass wipe — as long as technique and wetness are controlled.

Decision drivers

TX4009 earns its place when the program’s constraints are driven by surface behavior, not just “wipe availability”:

Nylon knit for surface interaction: selected when the wipe’s hand-feel and smear tendency matter on sensitive finishes.
Continuous-filament construction: long filaments in a stable knit support low-linting behavior under normal wiping force (no wiper is truly “lint-free” in every process condition).
Nonabrasive posture: positioned for surfaces vulnerable to scratching or micro-marring where rougher architectures can create cosmetic defects.
Published typical contamination context: typical values for particles/fibers, NVR, and ionic extractables support qualification discussions and change-control documentation.
Cleanroom laundering and packaging discipline: helps reduce handling-driven contamination and improves consistency across shifts and operators.
SOSCleanroom supply continuity: stable sourcing and documentation handoff reduce the risk of unqualified substitutions when demand spikes.

Materials and construction – explained like an engineer

“Nylon wiper” should not be treated as a commodity label. TX4009 is described as 100% continuous-filament nylon in a double-knit, no-run interlock pattern. That knit choice is not cosmetic — it is a mechanical control. Interlock knits resist unraveling, hold up under folding and edge handling, and tend to remain stable when pressed into corners or dragged across equipment surfaces where weaker fabrics can distort, snag, and shed.

Nylon’s practical value shows up in two places: surface gentleness (reducing scratch risk) and film behavior (how the wipe picks up, holds, and releases thin residues). If a process is sensitive to smear, streaking, or “looks clean until it dries” outcomes, nylon knit can be a defensible substrate choice — provided solvent loading and wipe-face discipline are controlled.

Specifications in context

TX4009 is supplied in a 9" × 9" format. In practice, 9 × 9 is a “control size”: large enough for quarter-folding into multiple clean faces, small enough to limit overreach and unintended contact with adjacent areas during wiping.

Packaging is listed as 150 wipers per bag with 12 bags per case, and a bag-within-a-bag presentation intended to support controlled introduction and staging. Treat the received case labeling and bag configuration as the governing control for kitting and SOP language.

Cleanliness and performance metrics

For most facilities, qualification risk reduces to three categories: releasables (particles/fibers), residues (NVR), and ions. TX4009’s published results should be treated as typical manufacturing capability data — useful for placement decisions and validation planning, not a substitute for process-window confirmation.

Particles (≥0.5 µm): typical 9.0 × 10⁶ /m².
Fibers (≥100 µm): typical 5,000 /m².
NVR: typical 0.020 g/m² (DI water) and 0.005 g/m² (IPA).
Sorptive capacity: typical 215 mL/m²; sorptive rate listed as <1 second.
Absorbency: listed as 1.5 mL/g.

Operational translation: TX4009 is designed to wet quickly and support film pickup without aggressive scrubbing. If streaking or haze appears after dry-down, the main levers are wetness control, fresh-face rotation, and single-direction stroke discipline — not more pressure.

Why packaging and traceability matter

Wipes become contamination variables through handling: open stacks, cross-station carry, reusing a loaded face, and “last wipe in the bag” behavior. The practical goal of double-bag style introduction is to reduce exposure time and touch events, and to keep lot identity intact for investigations. When a residue trend shifts, traceability and consistent sourcing shorten the variable window and keep corrective actions focused.

Best-practice use

Nylon knit performs best when technique is controlled. For smear-sensitive surfaces, the process goal is consistent pickup with minimal redeposition.

Quarter-fold for control: create multiple clean faces; treat each face as single-pass on critical surfaces.
One-direction strokes: use parallel, overlapping passes; avoid back-and-forth scrubbing that reworks dissolved soils.
Wetness discipline: aim for damp, not flooded. Over-wetting increases pooling and streak risk on dry-down.
Light pressure on optics/media-like surfaces: let chemistry and contact do the work; pressure is a defect mechanism on sensitive finishes.
Early discard rules: once a face is loaded, it becomes a redistribution tool.

Common failure modes — and how to prevent them

A wipe becomes a defect source in predictable ways: reusing a loaded face too long, inconsistent solvent loading, wiping abrasive textures with excessive force, and relying on “more pressure” to fix a film problem. TX4009’s knit stability and nonabrasive posture help, but procedural controls remain decisive: face rotation, directional strokes, and chemistry discipline.

Closest comparators

The most defensible comparisons are to other knit cleanroom wipes selected for surface gentleness, low-linting behavior, and documented cleanliness frameworks.

Contec Polynit Wipes (knife-cut edge polyester knit) are a close comparator when a facility wants an exceptionally soft knit for scratch-vulnerable surfaces, with published low particle/fiber positioning and cleanroom laundering/packaging controls.

Berkshire MicroSeal 1200 (sealed-edge polyester knit) is the appropriate comparator when edge-driven releasables dominate the risk model. If fibers/stringers trace back to folding and edge contact, sealed-edge formats are often the next technical step.

Rule of thumb: When surface gentleness and smear control are the constraint, evaluate knit selection and wetness discipline. When edge control becomes the acceptance driver, sealed-edge/sealed-border is typically the next control step.

Where TX4009 fits in a cleanroom wiping program

TX4009 fits as a specialty knit “surface-behavior” control in programs where gentle contact, smear risk, and consistent film pickup matter — commonly alongside a broader set of wipes used for spill control, general wipe-downs, and higher criticality finishing. When the program’s risk shifts to edge-driven fibers or the most defect-sensitive surfaces, the technical step-up is typically a sealed-edge or sealed-border knit. When wetness repeatability is the constraint, the step sideways is a controlled pre-wetted system designed to reduce operator variability.

Terminology note: TX4009 is engineered for low-linting performance; no wiper is truly “lint-free” in every process condition.
