Texwipe TX8691 Vectra® QuanSat™ LT 9" x 9" Low-TiO2 Polyester Cleanroom Wipers - Sealed Border - Pre-Wetted 6% IPA / 94% DIW - 50/Bag - 600/Case
Texwipe TX8691 Vectra® QuanSat™ LT is a non-sterile, pre-wetted cleanroom wiper manufactured from 100% polyester engineered for reduced titanium dioxide (TiO2) content. Developed for contamination-sensitive applications, TX8691 combines a sealed-border polyester substrate with Texwipe's automated Vectra® cleaning process and a factory-prepared 6% isopropyl alcohol (IPA) / 94% deionized water (DIW) cleaning solution.
Each nominal 9" x 9" wiper features thermally sealed borders designed to reduce fiber release from the edges. The continuous-filament polyester fabric provides mechanical strength and controlled wiping performance for compatible equipment, components, fixtures, and surfaces where particles, fibers, ionic residues, and material-derived contamination are important selection considerations.
The Vectra® LT substrate is specifically positioned by Texwipe for applications where titanium dioxide contamination may adversely affect a process or finished product. TiO2 is used in certain polyester manufacturing processes, and unwanted transfer of titanium-containing material may be a concern in sensitive applications. Texwipe describes TX8691 as a low-TiO2 wiper; however, the published technical sheet does not establish a numerical TiO2 concentration, detection limit, or guaranteed release threshold.
TX8691 is factory pre-wetted with 6% semiconductor-grade IPA and 94% DIW. The wetting solution is filtered to 0.2 µm before packaging. This formulation supports approved wet-cleaning procedures where a predominantly water-based cleaning solution is preferred and reduces the need for operators to prepare alcohol mixtures or wet individual dry wipers at the point of use.
The sealed-border polyester construction and automated Vectra® processing are designed to provide low levels of releasable particles, fibers, ions, and nonvolatile residues. These characteristics are useful when selecting cleaning materials for semiconductor, microelectronics, data-storage, precision manufacturing, and other controlled-environment applications requiring careful management of wiping-material contamination.
Texwipe identifies the Vectra® LT family for ISO Classes 1 through 6 and EU GMP Grades A through D. These manufacturer application designations are not certifications of a facility's cleanroom classification or evidence that the finished wiper is sterile. TX8691 is supplied non-sterile and must be qualified for the actual process.
TX8691 is supplied in reclosable slider bags containing 50 pre-wetted wipers each. Each manufacturer case includes 12 bags, totaling 600 wipers. SOSCleanroom offers both individual-bag and full-case purchasing options. The reclosable package helps protect unused wipers and limit evaporation when properly closed after dispensing.
Low-TiO2 Cleaning Advantage: TX8691 combines a reduced-TiO2 polyester design, thermally sealed borders, automated Vectra® cleaning, and factory-prepared 6% IPA / 94% DIW. It is intended for qualified wet-cleaning processes where substrate cleanliness, controlled solvent application, and titanium-containing contamination are important considerations.

Titanium Dioxide (TiO2) Control and Material Qualification:
Titanium dioxide is used in some polyester manufacturing applications, including as a pigment or delustering additive. In processes sensitive to titanium-containing contamination, the wiper substrate itself can become a material-selection consideration.
Texwipe identifies Vectra® LT QuanTex™ as a low-TiO2 polyester material. This is a documented design characteristic, but the published TX8691 technical sheet does not include a numerical TiO2 concentration, maximum release value, analytical detection limit, or batch-specific TiO2 acceptance criterion.
- Manufacturer Positioning: Low titanium dioxide polyester.
- Exact TiO2 Percentage: Not numerically established by the published TDS.
- Guaranteed Maximum: No ppm, ppb, or weight-percent limit stated in the reviewed TDS.
- Detection Method: No TiO2-specific analytical method is identified in the reviewed TDS.
- Lot-Specific Release: Do not assume each lot is certified to an unpublished titanium limit.
- Particle Characterization: General LPC and fiber counts do not separately identify titanium-containing particles.
- Residue Analysis: Total nonvolatile-residue measurements do not identify the chemical composition of the residue.
- Critical Applications: Request manufacturer evidence when a qualified process specifies numerical titanium contamination limits.
- Substitution Control: Do not assume ordinary polyester and low-TiO2 polyester are equivalent in titanium-sensitive processes.
Important TiO2 Qualification Guidance: TX8691 is described by Texwipe as low in titanium dioxide, not as analytically proven TiO2-free. When titanium limits are critical, request a numerical manufacturer specification, test method, reporting limit, and relevant lot documentation before approval.
Sealed-Border Polyester and Vectra® LT Processing:
TX8691 combines low-TiO2 polyester with thermally sealed borders and automated Vectra® processing. These features address different potential contamination sources and should be evaluated together during wiper qualification.
- Polyester Structure: Provides strength and flexible contact for controlled wiping.
- Thermally Sealed Borders: Reduce exposed fiber ends and associated edge shedding.
- Automated Cleaning: Helps lower removable particles, fibers, ions, and nonvolatile residues.
- Low-TiO2 Design: Addresses potential titanium-containing material contribution from the substrate.
- Abrasion Resistance: Designed for normal wiping of compatible abrasive surfaces.
- Surface Compatibility: Verify the substrate and chemistry with plastics, coatings, adhesives, and sensitive components.
- Wiping Limitations: Sharp edges, aggressive rubbing, and improper technique can still damage the material.
- Cleanliness Qualification: Compare the applicable manufacturer values with the facility's process limits.
Contamination-Control Guidance: Sealed borders, controlled cleaning, and reduced-TiO2 substrate design are complementary features. None independently guarantees an absence of contamination or replaces verification against the process's actual acceptance limits.
6% IPA / 94% DIW Chemistry and Comparison with 70% IPA:
TX8691 uses a factory-prepared 6% semiconductor-grade IPA / 94% DIW solution filtered to 0.2 µm. It is intended for qualified cleaning procedures requiring a predominantly water-based pre-wetted wipe, rather than procedures specifying the higher-alcohol chemistry of 70% IPA or 100% IPA products.

- Quantitative Wetness: Do not infer exact mL-per-wipe fill from sorptive-capacity data.
- Disinfection: No universal disinfectant contact time is established for TX8691.
- Sporicidal Requirements: Use a separately qualified sporicide when required.
- Safety: The lower concentration does not remove the manufacturer's flammable-solid classification.
Chemistry Guidance: TX8691 is a low-TiO2 polyester cleaning wiper pre-wetted with 6% IPA / 94% DIW. It should not be treated as a direct replacement for a sterile wipe, 70% IPA procedure, registered disinfectant, or qualified sporicidal treatment.
Recommended Contamination-Control Wiping Procedure:
The following general practices support consistent wiping but do not replace the facility's approved cleaning procedure or material qualification requirements.
- Verify Product Approval: Confirm TX8691 is qualified for the environment, chemistry, surface, and required titanium-contamination control.
- Inspect the Package: Check product identification, lot, expiration date, and bag integrity.
- Prepare the Work Area: Follow controlled-area material-transfer and equipment-cleaning procedures.
- Use Appropriate PPE: Wear suitable cleanroom gloves and protective equipment.
- Open the Slider Bag: Open only enough to remove the required wipe.
- Protect Unused Material: Avoid contact with contaminated gloves and work surfaces.
- Reseal Promptly: Close the bag to reduce evaporation and unnecessary exposure.
- Fold for Control: Create manageable clean wiping faces as specified by the SOP.
- Use Directional Strokes: Apply controlled, overlapping passes in the prescribed direction.
- Maintain Suitable Pressure: Avoid aggressive abrasion or damage to the substrate and equipment.
- Rotate Wiping Faces: Reduce redeposition by changing to clean surfaces of the wipe.
- Monitor Residue: Replace wipes when they become contaminated, damaged, dry, or begin leaving unacceptable residue.
- Observe Drying Requirements: Confirm the required final surface condition before restarting production.
- Discard After Use: Never return a used wipe to the original bag.
- Document the Process: Record lot and cleaning details where required.
Operational Guidance: Texwipe does not establish a universal wipe coverage area, cleaning-pass count, or TiO2 transfer limit for every TX8691 application. Define these parameters through actual process qualification, wiping studies, and contamination-control requirements.
Packaging, Evaporation and Lot Control:
TX8691 uses reclosable bags intended to help preserve the factory-prepared solution condition. Proper dispensing and storage are particularly important because evaporation, external contamination, and unapproved solvent additions can alter the wiping material during use.
- Close the Bag: Reseal immediately after dispensing.
- Minimize Air Exposure: Avoid prolonged open-package periods.
- Prevent Cross-Contamination: Keep unused wipes away from used gloves and uncontrolled surfaces.
- Inspect Wetness: Remove unexpectedly dry or compromised wipes.
- Do Not Top Off: Avoid adding solvent unless an approved process specifically permits it.
- Maintain Lot Traceability: Preserve original labeling and lot records.
- Follow Open-Pack Limits: Apply the facility's defined in-use controls.
- Check Expiration: The manufacturer specifies a one-year shelf life from manufacture for TX8691.

The TDS provides general particle, fiber, residue, and ion measurements, but it does not identify the titanium content of released particles or quantify TiO2 concentration in the finished wiping material. Earlier manufacturer documents published different typical measurements; use the current manufacturer-linked technical sheet for qualification planning.
Performance Data Guidance: Typical cleanliness measurements are not batch-specific guarantees. Low-TiO2 positioning must be assessed separately from general particles, fibers, and nonvolatile residues when a process has a numerical titanium-contamination limit.
