Texwipe TX7070 BetaMop® Microdenier String Refill Heads — Tubular Knit, Non-Sterile (Case of 6)

TX7070 is a microdenier, 100% polyester string mop head refill engineered for controlled-environment floor cleaning where streak-free results and high particle pickup matter (pharma, biologics, medical device, microelectronics, and semiconductor programs). The microdenier knit is designed to increase lifting and capture of small particles and support repeatable solution application/removal in critical environments.

For over 35 years, SOS and Texwipe have been close partners, and SOSCleanroom is the authorized Master Distributor of ITW Texwipe for the United States market. That relationship matters for cleanroom mopping programs: it supports continuity of supply, stable product lineage, and fast access to manufacturer documentation for qualification, change control, and audit readiness.

Low contamination control depends on technique, not just materials

A microdenier polyester knit can help improve pickup and reduce streaking, but performance in critical environments is driven by handling discipline: controlled wetting, two-bucket logic (where required), defined pass patterns, and strict change-out rules. Treat mop heads as contamination-controlled components.

Practical cleanroom use guidance (technicians and engineers)

Pre-wet consistency: Standardize the load (target wet pickup) so each head delivers the same film thickness. Over-wetting is a common root cause of residues and streaking.
Pass pattern discipline: Use defined, overlapping passes and a consistent direction to avoid re-depositing fines. Do not “scrub” in place unless the SOP calls for it (scrubbing increases abrasion risk and can mobilize debris from floor coatings).
Edge control: Keep the head face flat to the floor; avoid rolling the head onto its side where higher fiber contact can smear soils and push liquid into seams/edges of flooring.
Two-bucket logic (when used): Rinse/wring in the dirty bucket first, then recharge in the clean bucket. This reduces carryover and helps keep disinfectant concentration closer to target.
Change-out triggers: Replace the head when it becomes visibly loaded, begins streaking, loses wetting uniformity, or after the time/area limit defined by your contamination-control plan.

Key technical attributes (as published)

These items are published characteristics used for planning, qualification, and SOP development. Validate under your site conditions and disinfectant set.

Attribute	Published value	What it means on the floor
Material / construction	Knitted, tubular microdenier, 100% polyester	Microdenier knit is used to improve pickup of small particles and support streak-free cleaning when wet load and technique are controlled.
Capacity (typical)	1.8 liters/head	Supports stable solution delivery over a defined area. Use capacity as a planning number; actual delivered film depends on wringing method and floor texture.
Packaging	6 heads/case; non-sterile, double-bagged	Double-bagging supports controlled introduction and staging outside the clean area without exposing the inner bag until point of use.
Cleanroom environment	ISO Class 3–7; EU Grade A–D	Appropriate for critical environments when paired with the correct bucket/wringer controls and room-specific technique.
Disinfectant compatibility	Compatible with most disinfectants (as published)	Helps programs standardize across common chemistries. Always confirm compatibility with your strongest oxidizers and any specialty formulations.
Autoclave	Autoclave safe (as published)	If your program uses autoclaving, qualify cycle parameters (time/temperature/dry) and define max cycles in the SOP.

Process control table (for SOP writers)

Control point	Recommended practice	Risk if missed
Introduction to clean area	Keep the inner bag closed until point of use; stage in a designated clean storage location.	Particulate and residue pickup on the mop head before first use; avoidable contamination events.
Wetting / charging	Standardize dwell time in solution and wring pressure; target repeatable wet pickup across operators and shifts.	Streaking, residues, disinfectant under-dosing, or excessive pooling that drives slip hazards and corrosion concerns.
Area limits / change-out	Define max area or time per head and enforce a hard replacement rule when loading is visible or performance changes.	Soil re-deposition, bioburden spread, and inconsistent disinfectant contact time delivery.
Reuse / laundering (if permitted)	If your program rewashes, track cycles by lot/head and set a maximum cycle count; verify cleanliness after laundering.	Loss of pickup, increased shedding from abrasion, detergent residues, and uncontrolled variability across mop heads.

Compatibility and solution notes

Disinfectants: Published as compatible with most disinfectants. Standardize your wet load and wring method to keep concentration and contact time consistent across the floor.
Residue control: Many “streaking” events are actually chemistry residue plus over-wetting. Tighten wring consistency, then validate rinse steps (if your SOP includes them).
Autoclave use: If autoclaving is part of your program, qualify the cycle and document the max number of cycles allowed under your process controls.
DI water / aqueous rinsing: Not published as a specific protocol for this refill. If your SOP requires aqueous rinse or neutralization, qualify under your site conditions and floor finishes before full rollout.

Common failure modes

Streaking / filming: Typically from inconsistent wringing, over-wetting, or chemistry residue. Prevent with wet pickup targets, standardized wring pressure, and defined pass patterns.
Cross-contamination carryover: Dirty-bucket drift, wrong bucket order, or extending head life beyond limits. Prevent with two-bucket discipline (where used) and hard change-out rules.
Particle re-deposition: Caused by using a loaded head past its effective capacity or reusing heads without validated laundering controls. Prevent with area/time limits and documented reuse limits.
Head damage / shedding risk: Abrasion against floor damage, sharp debris, or aggressive scrubbing. Prevent by removing sharp debris first and using the correct tool for stuck soils.
Residue transfer to critical zones: Mop head touches carts, wheels, or dirty staging areas between passes. Prevent with defined staging zones and “clean side/dirty side” handling.

Storage and handling best practices

Keep refills in original packaging until point of use; open the inner bag only in the controlled area (or per your material transfer SOP).
Segregate clean and used heads immediately after use (dedicated bags/containers). Do not place used heads on carts or benches.
If reusing, document cycle counts and laundering conditions; do not exceed the site-approved maximum cycles.
Store dry, protected from dust and chemical vapors; avoid compressing heads under heavy loads that can deform the knit and change wetting behavior.

The Technical Vault Cleanroom Mopping Systems & Techniques (Applied Use Case: Texwipe™ TX7070 BetaMop™ Tubular Microdenier String Refill Heads)

Purpose & Scope

TX7070 are replacement mop heads for the Texwipe™ BetaMop™ system, using a tubular microdenier polyester string format designed to improve fine-particle pickup while maintaining controlled-environment compatibility. This Technical Vault entry focuses on what matters operationally: solution control, lane discipline, change-out rules, and why microdenier behavior changes both performance and risk.

Visual Aids (Technique, Zoning, Lifecycle)

Use this graphic as a training reinforcement tool: stroke discipline, zone-based tool control, and mop head lifecycle management.

Implementation note: Diagram intent is educational. Align technique, zoning, and change-out rules to your facility SOP and validated cleaning program.

What “Microdenier” Changes (Performance + Handling)

Microdenier fibers have a finer filament structure that can improve pickup of smaller particles and thin films. In practice, microdenier string heads can feel “grabbier” on some floor finishes and may hold contaminants more effectively—meaning change-out discipline becomes even more important. The goal is improved capture without increasing redeposition risk through overuse.

Higher surface area: potential for improved fine-particle pickup.
Higher retention: can hold residues/soils effectively—do not “stretch” usage beyond defined limits.
Different drag behavior: may increase streaking if over-wet or if pressure becomes inconsistent.

Technique Guidance (Microdenier String Heads)

Saturation & Drip Control (Critical)

Target damp-to-wet loading; avoid visible dripping before entering the controlled area.
Over-wetting increases pooling and can create drag lines; microdenier heads may show this sooner on smooth floors.
Use a controlled loading method (bucket/wringer procedure or defined pre-wet method) to reduce operator variation.

Lane Discipline & Change-Out Logic

Work in defined lanes; avoid random “wandering” that spreads loaded soils across zones.
Define maximum area/time per head in SOP (risk-based by traffic and soil load).
Do not re-enter cleaner zones with a head used in thresholds, drains, door tracks, or perimeter edges.

Pressure

Avoid aggressive scrubbing. Excess downforce can squeeze captured soils and solution out of the fibers and increase redeposition risk. Apply consistent, moderate pressure and let chemistry + controlled passes drive removal.

Mop Head Lifecycle Control (Microdenier-Specific Notes)

Microdenier heads can remain visually intact while performance shifts. Define objective triggers for change-out and investigate streaking/haze as a possible overuse or over-wetting indicator.

Change-out triggers: increased streaking, slower drying, loss of pickup, persistent residue odor, or validated maximum-use limits.
Segregation: dedicate heads by zone and chemistry family where applicable.
Do not “save it for later”: leaving damp, used heads in storage increases residue set and can degrade performance.

Storage, Segregation & Handling

Store heads dry and protected; avoid contact with floors and uncontrolled surfaces.
Label storage by zone and chemistry to prevent cross-use.
Do not transport used heads through cleaner zones without containment controls defined by SOP.
Inspect attachment points and tailbands for integrity; uncontrolled flaring reduces lane control and can increase redeposition.

Frequency & Standards Context (ISO & USP)

Cleaning frequency is typically established as a risk-based program supported by SOPs, training, and effectiveness monitoring. ISO-classified operations generally expect documented rationale and repeatable execution. USP-regulated compounding spaces commonly require routine floor cleaning and strict tool segregation aligned to the facility contamination control strategy.

SOP & Audit Readiness Checklist (Microdenier String Heads)

Define solution loading method and acceptable wetness (no dripping; no pooling).
Define lane discipline and maximum area/time per head (risk-based) plus disposal rules.
Segregate by zone and chemistry; label storage and transport to prevent cross-use.
Define lifecycle triggers and investigate streaking/haze as potential over-wetting or overuse indicators.
Document training and periodic effectiveness review (visual inspection + EM trend review where applicable).
