Texwipe TX7118M AlphaMop™ Microdenier Cleanroom Replacement Mop Covers — Fits 8" x 15" Flat Mop Heads, Non-Sterile
TX7118M is a microdenier (microfiber-style) mop cover engineered for critical cleaning where higher contaminant capture and streak-free solution application matter — including routine cleaning of walls, ceilings, and floors, plus applying and removing disinfectants (with specific design intent for quat-based cleaners). It is used with Texwipe’s AlphaMop™ 8" x 15" flat mop head systems (including TX7108 and TX7108A).

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 when you are standardizing cleanroom mopping: it supports continuity of supply, stable product lineage, and fast access to the manufacturer documentation your QA/QC team expects.
Published configuration (TX7118M)
  • System fit: Designed for 8" x 15" (20 cm x 38 cm) AlphaMop™ flat mop heads; works with TX7108 and compatible AlphaMop heads.
  • Cover material: 100% polyester microdenier (microfiber-style textile), never a blend.
  • Sterile / non-sterile: Non-sterile.
  • Inner packaging (as published): 25 mop covers and 1 pad per bag.
  • Case packaging (as published): 6 bags per case = 150 mop covers per case.
  • Pads included (as published): 6 polyester pads per case (used to cushion the head and help the cover conform to surfaces for consistent contact).
  • Cleanroom environment (as published for AlphaMop system): ISO Class 2–7 and ISO Class 3–7 are both published across AlphaMop technical documentation (programs should qualify to their own limits).
  • Shelf life (as published for AlphaMop covers): Non-sterile — 5 years from date of manufacture.
  • Autoclave: Microdenier covers are published as autoclave safe; cover-specific cycle conditions are not stated — qualify under your site’s autoclave recipe before standardizing for sterile transfer workflows.
Low particle/fiber intent — and the reality check
TX7118M is built to increase capture of fine contamination (microdenier construction with more fibers and more surface area than standard polyester covers). Even so, no textile cover is truly zero-shedding in every use scenario. Treat mop covers like process consumables: control how they are introduced, how often they are changed, and how aggressively they are used on abrasive surfaces.
Practical cleanroom use guidance (technicians and engineers)
  • Change-cover discipline (core control): Use the AlphaMop quick-change approach intentionally — replace covers frequently to avoid redepositing captured contamination. Define a change trigger in your SOP (area cleaned, time in use, or visible loading).
  • Clean-to-dirty pattern: Mop from the cleanest zone toward the dirtiest zone (or highest-risk product area outward) and avoid backtracking with the same cover.
  • Overlap and edge control: Use controlled, overlapping strokes (e.g., S-stroke) with consistent pressure. Avoid scrubbing the same line repeatedly; that can drive streaking and can increase mechanical shedding on rough surfaces.
  • Pad and conformity: Install the polyester pad correctly so the cover maintains full contact. Poor pad seating reduces contact area and increases streak risk, especially on walls/ceilings.
  • Residue removal approach: For disinfectants that can leave films, plan a defined removal step (fresh cover and appropriate removal chemistry per site policy) rather than trying to “buff out” residue with an overused cover.
Cleaner and disinfectant use notes (published intent)
  • Quat workflow: The microdenier AlphaMop M Series cover is engineered to work with quat-based cleaners/disinfectants and is positioned to help avoid performance loss associated with quat breakdown in some wiping substrates.
  • Application + removal: AlphaMop documentation positions the system for applying and removing solutions including disinfectants (walls, ceilings, floors). Validate contact time and removal practices under your SOP.
  • Solvent use: AlphaMop technical documentation references cleaning with solvents such as IPA, ethanol, acetone, and degreasers at the system level. Compatibility is process-dependent — qualify your chemistry and surface combination before broad release.
Why microdenier matters (mechanism-based)
Microdenier fabric is published as having increased capturing power versus standard polyester materials (more fibers and more surface area). The smaller filament diameter supports lifting and holding fine contamination (including particles as small as microbes) while improving solution coverage for large-surface cleaning.
Published mechanism What it helps with in the field How to operationalize
Higher fiber density / surface area (microdenier) Improved fine contaminant pick-up; reduced “push-around” behavior Define cover-change intervals; avoid overloading a single cover on high-soil passes
Enhanced sorption / wicking (published for microdenier covers) More uniform wet film; fewer dry streaks on large panels Pre-wet consistently or control dispense volume; avoid flooding edges and seams
Designed intent for quat cleaning Improved performance when using quat disinfectants in routine cleaning Use defined application/removal steps; do not “stretch” a cover through multiple rooms

Common failure modes 
  • Streaking / film trails: Typically from inconsistent wetting, overloaded covers, or uneven pad seating. Prevent with controlled dispense volume, correct pad installation, and more frequent cover changes.
  • Residue carryover: Caused by continuing to mop after the cover is loaded (or moving between rooms/grades with the same cover). Prevent by defining area-per-cover limits and enforcing clean-to-dirty zoning.
  • Particle shedding on abrasive surfaces: Triggered by aggressive scrubbing on rough coatings, damaged epoxy, or sharp edges. Prevent by reducing mechanical aggression and addressing the surface defect as a maintenance item.
  • Cross-contamination from handling: Touching the working face during installation or setting the mop head down on non-controlled surfaces. Prevent with glove discipline and controlled staging (clean cart, clean tray, or hanging storage).
  • Coverage loss in corners/edges: Poor conformity when the pad is missing, worn, or incorrectly installed. Prevent by verifying pad presence and replacing pads when compression set is observed.
Storage and handling best practices
  • Keep covers and pads in original packaging until introduced into the controlled area; open bags at point-of-use to minimize airborne deposition.
  • Store cases in a clean, dry location; avoid humidity extremes that can complicate controlled wetting and can drive inconsistent wipe film.
  • Stage only the quantity needed for the shift to reduce repeated bag opening and handling events.
  • If your program autoclaves covers, segregate “to-be-autoclaved” inventory and apply clear status labeling to prevent mix-ups.

The Technical Vault Flat Mop Microdenier Performance Control (Applied Use Case: Texwipe™ TX7118M AlphaMop™ Microdenier Replacement Covers)

Purpose & Scope

The TX7118M AlphaMop™ covers use a microdenier cleaning surface designed to increase effective contact area and improve pickup of fine residues and particulates during controlled mopping. Microdenier can be a performance advantage—but it also raises the importance of solution control, lane discipline, and change-out rules because higher capture ability often means the cover loads sooner than operators expect.

Visual Aids (Technique, Zoning, Lifecycle)

Use this graphic as a training reinforcement tool: unidirectional strokes, zone-based tool control, and cover 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 + Risk Controls)

Microdenier surfaces increase available fiber surface area and can improve pickup of fine residues on smooth floors and process areas. However, that improved pickup often results in faster loading, which increases the importance of objective cover-change rules. The outcome you want is improved capture without turning the cover into a vehicle for redeposition.

  • Higher surface area: potential for improved fine-particle pickup and thin-film removal.
  • Higher retention: the cover may hold soils effectively—do not “stretch” usage beyond SOP limits.
  • Drag sensitivity: microdenier can show streaking sooner if over-wet or if pressure varies.

Technique Guidance (Microdenier Flat Mop Covers)

Unidirectional Lanes & Overlap

  • Use unidirectional strokes with 10–20% overlap to prevent missed lanes.
  • Avoid back-and-forth scrubbing that can redeposit captured soils and create drag lines.
  • Keep the head flat and avoid edge riding; microdenier can “print” edge bias into the lane.

Saturation Control (Damp-to-Wet, Not Dripping)

  • Target a consistent damp-to-wet load to avoid pooling and haze.
  • Over-wetting is a common cause of streaking with microdenier covers on smooth floors.
  • If your SOP requires dwell + removal, define the removal step clearly to prevent residues.

Pressure (Keep It Consistent)

Microdenier covers can be more sensitive to pressure variation. Excess downforce can create drag lines and squeeze captured soils back onto the surface. Apply consistent, moderate pressure and let lane discipline do the work.

Cover Change-Out Discipline (Microdenier Loads Faster Than “It Looks”)

Treat each cover as a finite-capacity capture medium. In ISO-controlled environments, soil loading can be invisible. Strong programs define a change-out rule based on zone boundary, time, or area covered, rather than “when it looks dirty.”

  • Change by boundary: do not take a used cover from entries/thresholds back into cleaner field areas.
  • Change early in high-soil areas: corners, drains, door tracks, and perimeters load microdenier quickly.
  • Segregate by chemistry: avoid cross-chemistry carryover unless explicitly permitted by SOP.

Details Most Sites Skip (But They Explain Streaking)

  • Pad seating: a mis-seated foam pad can create pressure gradients that appear as repeating rail lines.
  • Floor finish interaction: microdenier can “grab” more on some finishes; reduce downforce and control wetness.
  • First-lane bias: the first lane after loading may be wetter; avoid flooding the first pass.
  • Glove transfer: handling clean covers with wet/dirty gloves can contaminate covers before surface contact.

SOP & Audit Readiness Checklist (Microdenier Covers)

  • Define technique: unidirectional strokes, overlap, and head-flat expectations.
  • Define saturation rules (damp-to-wet; no dripping) and validated dwell/removal steps if applicable.
  • Define change-out rules by zone/time/area (not appearance alone), with stricter limits for high-soil areas.
  • Define segregation by room/zone and chemistry family where applicable; label storage and transport.
  • Train troubleshooting: check technique, cover change-out, foam pad seating, and head flatness before changing chemistry.

Disclaimer: This Technical Vault content is provided for educational purposes only. Manufacturer instructions, facility SOPs, and site-specific risk assessments must always take precedence. Cleanroom suitability and contamination performance are determined by the complete system configuration (cover + pad + head assembly + chemistry + handling) and validated site practice.
