Texwipe TX3224 Sterile TexTra 10 (9" × 9") is designed for controlled environments where a wipe is not just “clean”—it is part of the process control stack. When the work is aseptic or inspection-driven, the failure modes are predictable: edge-driven fibers, inconsistent wetness that changes soil removal and dry-down, and breaks in sterile handling that force rework or deviation documentation.

TX3224 addresses those risks with a thermally sealed border to reduce edge releasables, a high-absorbency polyester knit to stabilize wetness behavior, and a gamma-irradiated sterile presentation intended to support disciplined introduction into critical areas. SOSCleanroom supports program stability with reliable sourcing, consistent documentation handoff, and continuity of supply so teams are not pushed into unqualified substitutions when schedules tighten.

TX3224 is intended for aseptic and controlled wiping where sterile presentation and edge control matter: wipe-downs in ISO-class cleanrooms, cleaning work surfaces and equipment exteriors, and controlled application/removal of approved solutions where the wipe must maintain integrity and minimize releasables. It is commonly selected when teams want a sterile, sealed-border polyester knit that can absorb and hold liquid without turning into the uncontrolled variable.

TX3224 earns its place in a sterile wiping program based on a small set of technical controls:

• Sterility posture: gamma irradiated with a stated 10⁻⁶ SAL and method alignment to ISO 11137, supporting aseptic introduction and audit expectations when handled correctly.
• Edge strategy: thermally sealed border to reduce edge-driven fibers and particle release during folding and aggressive wipe patterns.
• Substrate and construction: 100% continuous-filament polyester, single-ply, double-knit designed for durability and low-linting behavior under wiping force.
• Absorbency as a control lever: high published sorptive capacity helps stabilize “damp vs. wet” outcomes in real workflows where over-wetting causes pooling and redeposit.
• Packaging discipline: sterile barrier packaging designed to support staged introduction and reduce handling exposure.
• Traceability: lot-level documentation posture supports investigations when a trend shifts and change control matters.

“Polyester sterile wipe” is still too broad. The contamination mechanism often comes from edges and abrasion, not the label. TX3224 uses continuous-filament polyester in a stable double-knit construction, then adds a thermally sealed border to reduce the loose ends and edge degradation that show up when operators fold aggressively, wipe quickly, and press into corners.

Practical outcome: the wipe is designed to stay intact and maintain low-linting behavior under real wiping force—especially important when the wipe is used near open product, critical surfaces, or validated cleaning/disinfection steps.

• Size: 9" × 9" (nominal).
• Material: 100% continuous-filament polyester; single-ply, double-knit construction.
• Edge/border: thermally sealed border for edge control.
• Absorbency framework: basis weight listed at 233 g/m², supporting the “high-absorbency knit” behavior expected for this family.
• Packaging (operational planning): commonly listed as 100 wipers per bag, 5 bags per case (total 500/case); inner presentation is often described as staged inner packs to support controlled introduction.
• Sterility: gamma irradiated; stated 10⁻⁶ SAL with ISO 11137 alignment.

For most sterile programs, the qualification lens is: releasables (particles/fibers), residues (NVR), and wetness behavior (how the wipe absorbs, holds, and releases liquid). TX3224’s published typical values should be treated as a starting point for validation and method suitability—not as a contractual per-lot specification.

• Sorptive capacity: 600 mL/m² typical; sorptive rate 0.3 seconds typical. Operational meaning: fast wet-out with strong liquid hold—useful for stabilizing damp wiping and avoiding “pool and streak” failures caused by over-application.
• Particles (LPC): typical counts reported across size bands (e.g., >0.5 µm, >5 µm). Technical meaning: supports placement discussions, but technique still dominates outcomes (face rotation, pressure, and surface texture).
• Fibers: very low published typical fiber levels for a sealed-border knit format; edge control is the key mechanism.
• NVR: typical NVR reported (IPA and DI water extractants). Technical meaning: for haze/streaking, first check wetness control, chemistry concentration, and “overworking one face” behavior before blaming the substrate.

Sterility is not a label—it is a handling system. A sterile, gamma-irradiated wipe reduces the facility burden of in-house sterilization cycles, packaging compatibility checks, and post-cycle performance verification (strength, shedding, residue). The operational win shows up during deviations: when a contamination event occurs, sterile packaging and lot traceability can narrow the variable window, shorten investigations, and reduce the risk of undocumented substitutions.

• Sterile transfer discipline: disinfect exterior packaging per SOP, open the outer bag in the correct zone, and present the sterile inner bag to the sterile field without cross-contact.
• Fold for control: quarter-fold into stable faces; treat each face as single-pass in higher-risk wipe-downs.
• Directional strokes: use straight-line, overlapping passes; avoid back-and-forth scrubbing that redeposits dissolved soils.
• Wetness control: target damp wiping; avoid over-wetting that causes pooling, seam wicking, and dry-down residue patterns.
• Change-out triggers: discard early when loaded; a saturated face becomes a redistribution tool.

A wipe becomes a process problem in repeatable ways: breaking sterile barrier handling, over-wetting and pooling, reusing a contaminated face, and edge degradation on abrasive features. TX3224’s sealed-border knit is designed to reduce edge-driven releasables during folding and wiping force, while the high absorbency helps stabilize wetness behavior. The remaining controls are procedural: sterile transfer discipline, face rotation, and chemistry management.

The most defensible comparisons are to other sterile, sealed-edge/sealed-border polyester wipes intended for similar ISO ranges and wiping tasks.

Contec Sterile Quiltec® I (two-ply quilted polyester with heatsealed edges) is a close comparator when maximum sorptive capacity is the priority. Quilted, multi-layer constructions often compete directly with high-absorbency knit wipes when teams are trying to reduce wipe counts during wet wipe-downs while staying in a sealed-edge, low-releasables posture.

Berkshire Choice® 900 (sealed-edge polyester category) is an appropriate comparator when the decision driver is sealed-edge polyester wiping economics and consistency for critical cleaning tasks. When sterility is mandatory, ensure you are comparing against the supplier’s sterile offering and documentation package—not just the base substrate family.

TX3224 fits as a sterile, sealed-border “daily driver” for programs that need controlled releasables and stable wetness behavior during wipe-downs. It is most valuable where sterile introduction, edge control, and absorbency must work together: aseptic suites, critical staging zones, and wipe-down steps close to product or high-defect-sensitivity surfaces. When the constraint shifts to ultra-low residue finishing, pair the wipe-down with a validated chemistry and technique strategy—and document the role separation between routine wiping, final-touch finishing, and sampling.
