TX1012 Alpha10 12" x 12" Polyester Cleanroom Wiper

TX1012 Vectra Alpha10 is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), sealed-border polyester knit wiper engineered for critical cleaning, spill control, and solution application where contamination control is paramount. It is made from a no-run interlock, double-knit 100% continuous-filament polyester and uses Texwipe’s sealed-border technology (four fully sealed borders) to help minimize fiber and particle release—especially during rigorous wiping or when working on more abrasive surfaces and process-tool interiors (process-dependent).

Best-seller note: TX1012 is widely specified when teams want a 12" x 12" sealed-border knit that supports repeatable wipe-down outcomes in high-sensitivity environments, with strong lot traceability and Bag-Within-A-Bag cleanroom packaging for audit readiness and transfer discipline.

About the Manufacturer:

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. In Vectra® Alpha® 10, that shows up in sealed-border knit construction (edge control as a contamination-risk lever) and an automated Vectra® cleaning approach intended to drive low levels of ions, nonvolatile residue (NVR), particles, and fibers for critical cleaning applications.

Texwipe also positions Alpha® 10 for broad chemical compatibility and program alignment in controlled environments, including published guidance that it meets USP <797> and USP <800> wiper expectations and is autoclave safe (site validation required). SOSCleanroom (SOS) supports that manufacturing 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 standardize wiping materials with predictable performance while maintaining procurement reliability and audit readiness.

Traceability confidence: Lot-to-lot traceability and clean packaging support audit readiness and controlled transfer

Common Applications:

Wiping interior of process tools and other equipment
General wiping where contamination control is of paramount importance
Applying and removing lubricants, adhesives, residues, and other solutions including disinfectants
Cleaning with solvents such as isopropyl alcohol (IPA), ethanol, acetone, and degreasers (verify compatibility to your chemistry and SOP)
Lining trays for holding, protecting, drying, and storing of parts, equipment, and devices
Use on abrasive surfaces where a sealed border helps reduce snag/abrasion-driven shedding (process-dependent)

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 avoid re-depositing contamination.
Wet vs. dry: For solvent wipe-downs, dampen—do not over-saturate—so you maintain control and reduce dripping.
Abrasive surfaces: Let the sealed border do the work—avoid aggressive scrubbing that can abrade residues into surfaces; increase wipe changes instead.
Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins to streak (surface and chemistry dependent).

Selection Notes (TX1012 vs. Other Options)

TX1012 vs. TX1010: Same Vectra Alpha10 sealed-border knit; choose TX1010 (9" x 9") for tight work areas and smaller parts; choose TX1012 (12" x 12") when coverage per wipe matters on larger panels, benches, and tool surfaces.
Sealed-border Alpha10 vs. cut-edge AlphaWipe (TX1013/TX1009/TX1009B): Choose sealed-border when edge control and abrasion-driven shedding risk are dominant; choose cut-edge knits when general-purpose wiping is the priority and your SOP/process limits permit.
Dry vs. pre-wetted: If you want consistent wetting and reduced solvent handling, consider pre-wetted AlphaSat with Vectra Alpha10 options (site validation required).

Sealed-Border Control at 12" × 12" Scale: Why TX1012 Alpha10 Is Built for High-Defect-Sensitivity Wipe-Downs

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

Texwipe TX1012 Alpha10 (12" × 12") is a dry, double-knit polyester cleanroom wiper engineered for programs where edge-driven releasables are a real defect mechanism—not a theoretical risk. The wiper uses a fully sealed-border strategy intended to prevent fiber and particle release from the perimeter during folding, corner work, and higher-force wiping. :contentReference[oaicite:1]{index=1}

In day-to-day terms, TX1012 is selected when teams want a larger-format wipe for tool interiors, equipment wipe-down stations, and broad-area passes—but do not want the larger wipe to introduce an “edge variable” as operators rotate faces and work into seams. It is positioned for critical environments and is commonly evaluated anywhere the wipe is physically stressed: brushed stainless, fasteners, access panels, and process-tool interiors. :contentReference[oaicite:2]{index=2}

Program note: Low-linting performance is an engineering target, not a promise of “zero lint.” No wiper is truly lint-free in every process condition.

What it’s for

TX1012 is positioned for Class 1–100 use and is described as ideal for wiping the interior of process tools, general wiping where contamination control is paramount, and multi-application use in critical cleanroom environments. :contentReference[oaicite:3]{index=3}

On the SOSCleanroom listing, TX1012 is also mapped across ISO classes ISO 2 through ISO 8, which is helpful for initial placement discussions— with final suitability still dependent on your surface sensitivity, chemistry, and acceptance criteria. :contentReference[oaicite:4]{index=4}

Decision drivers

TX1012 earns its place in a cleanroom wiping program based on a short list of technical controls:

Sealed-border edge strategy: four fully sealed borders intended to reduce edge-driven fiber/particle release during folding and forceful wiping. :contentReference[oaicite:5]{index=5}
Substrate and knit stability: a no-run interlock, double-knit made from 100% continuous-filament polyester, selected to resist unraveling and maintain integrity under abrasion. :contentReference[oaicite:6]{index=6}
Performance balance: positioned for an excellent balance of wiping efficiency, abrasion resistance, and absorbency for a dry polyester knit. :contentReference[oaicite:7]{index=7}
Contamination framework: positioned around ultra-low levels of ions/extractables and minimized fiber/particle release to support qualification conversations. :contentReference[oaicite:8]{index=8}
Packaging discipline: solvent-safe Bag-Within-A-Bag cleanroom packaging supports controlled introduction and staging. :contentReference[oaicite:9]{index=9}
Traceability: “complete traceability of each bag” is part of the posted benefit posture, which matters during investigations and change control. :contentReference[oaicite:10]{index=10}

Materials and construction – explained like an engineer

“Polyester cleanroom wiper” is a category label—not a spec. What matters for releasables is continuous-filament construction (long filaments) and knit stability under stress. TX1012 is described as 100% continuous-filament polyester in a double-knit, no-run interlock. That “no-run” behavior is the control: when a wipe is snagged, folded into corners, or dragged along a textured surface, the knit is intended to resist unzipping and shedding spikes. :contentReference[oaicite:11]{index=11}

The second control is the border. In many real workflows, edge degradation is the start of the failure chain—especially when operators pinch-fold, wipe into seams, or use high contact pressure to remove films. TX1012’s sealed-border strategy is positioned specifically to reduce that edge-driven risk. :contentReference[oaicite:12]{index=12}

Specifications in context

Size: 12" × 12" (larger format supports broader-area, fewer-pass wiping when technique is disciplined). :contentReference[oaicite:13]{index=13}
Material: Polyester (continuous-filament, double-knit; no-run interlock). :contentReference[oaicite:14]{index=14}
Edge: Sealed border (control for edge-driven releasables during folding and higher-force wiping). :contentReference[oaicite:15]{index=15}
Packaging: 100 wipes per bag (double-bagged); 10 bags per case; solvent-safe Bag-Within-A-Bag packaging is called out. :contentReference[oaicite:16]{index=16}
Use environment mapping: Listed across ISO 2–ISO 8 on the SOSCleanroom page; also described for Class 1–100 use in the manufacturer-positioned application list. :contentReference[oaicite:17]{index=17}

A practical note for SOP writers: a 12" × 12" wipe increases the probability of accidental contact with adjacent surfaces if folding discipline is casual. If you standardize TX1012, standardize the fold and the “face life” rules with it.

Cleanliness and performance metrics

For most facilities, the qualification discussion clusters into three risk categories: releasables (particles/fibers), residues (NVR), and ions (corrosion/ECM sensitivity). TX1012 is positioned around minimized fiber/particle release and ultra-low ions/extractables, which is the right framework for determining where it belongs in your process flow. :contentReference[oaicite:18]{index=18}

Treat published values as qualification starting points, then validate in your window: your chemistry, your wipe pressure, your dry-down behavior, and your defect modes. Many “wipe failures” trace back to technique drift (overworking a face, circular scrubbing, inconsistent wetness) more than the substrate itself.

Why sealed-border matters operationally

If your operators fold and pinch into corners (which they will), the wipe’s perimeter becomes a working surface. A sealed-border design is meant to reduce the chance that the edge turns into a generator—especially during aggressive wipe patterns or on rougher finishes. TX1012’s border strategy is called out as a key control to prevent release of fibers and particles. :contentReference[oaicite:19]{index=19}

Rule of thumb: When edge control becomes the acceptance driver, sealed-border/sealed-edge is typically the next technical control step. When wetness repeatability becomes the constraint, consider a controlled pre-wetted system.

Best-practice use

TX1012 performs best when technique is as controlled as the wipe:

Quarter-fold consistently to create multiple clean faces; treat each face as single-pass for critical wipe-downs.
One-direction, overlapping strokes reduce redeposit and help you see when the wipe face is loaded.
Control wetness if using solvents/cleaners: aim for damp wiping that lifts and captures, not over-wet wiping that pools and spreads.
Change-out early: a loaded face is a redistribution tool, regardless of how engineered the wipe is.
Protect defect-sensitive surfaces: use lighter pressure and avoid dry scrubbing on textured finishes.

Common failure modes — and how TX1012 helps

A wiper becomes a contamination source in predictable ways: edge degradation during rough wiping, snagging and knit damage, reusing a contaminated face too long, and leaving residues due to inconsistent solvent loading. TX1012’s sealed-border strategy and no-run knit are positioned to reduce edge-related and snag-related degradation, while the remaining controls are procedural: face rotation, directional strokes, and chemistry discipline. :contentReference[oaicite:20]{index=20}

Closest comparators

The most defensible comparisons are to other 12" × 12" polyester knit cleanroom wipes intended for similar ISO ranges and defect-sensitivity.

Berkshire MicroSeal 1200 (sealed-edge polyester knit) is the right comparator when edge-driven releasables are the primary risk. Sealed-edge formats are often selected when folding and perimeter contact dominate the wiping pattern.

Contec Polynit (knife-cut edge polyester knit) is a practical comparator when surface gentleness and “hand feel” are priority constraints, with the trade-off that edge strategy differs from sealed-border controls.

Where TX1012 fits in a cleanroom wiping program

TX1012 is a strong selection for critical wipe-downs where you want a larger-format polyester knit wiper with a deliberate edge-control strategy: process-tool interiors, equipment wipe-downs, and broader-area wiping where folding and perimeter contact are unavoidable. It is best deployed with standardized folding, face-life rules, and chemistry discipline—so the engineered controls in the wipe translate into repeatable outcomes on the floor. :contentReference[oaicite:21]{index=21}

Terminology note: TX1012 is engineered for low-linting performance; no wiper is truly “lint-free” in every process condition.
