Wholesale Cloth TENS Electrodes | White Cloth Pads | TOP-RANK
B2B white cloth TENS electrodes. Engineered with multidirectional spunlace non-woven backing for extreme joint conformability without edge-lifting or hydrogel delamination during kinematic therapy.
Product Overview
The "White Cloth" TENS electrode represents the absolute baseline standard for professional physiotherapy clinics and high-volume medical distributors. Diverging from rigid PE foam pads, this transdermal interface utilizes a medical-grade spunlace non-woven fabric backing. It is specifically formulated to handle high-kinematic areas of the human body, such as articulating knees, elbows, and cervical curves. The soft, cloth-based architecture allows the pad to stretch and conform to dynamic muscular topography, ensuring the underlying hydrogel maintains uninterrupted Z-axis electrical contact. We mass-produce these high-turnover consumables in bulk for global physical therapy networks and OEM hardware brands.
Technical/Engineering Description
The structural integrity of this pad begins with the hydroentanglement process of the spunlace fabric. High-pressure water jets mechanically interlock the polyester/viscose fibers without the use of chemical binders. This yields a backing that is soft, highly breathable, yet structurally resistant to diagonal tearing. To convert this fabric into an electrode, a highly conductive carbon-loaded polymer film is hot-melt laminated to the underside. This film acts as an absolute barrier; it distributes the electrical charge evenly while physically preventing the aqueous hydrogel from bleeding through the porous cloth fibers. The final product is die-cut into 50x50mm, 50x100mm, or custom geometries. Standard commercial output mandates a minimum order quantity (MOQ) of 20,000 units for unbranded wholesale.
Key Features
-
Multi-Directional Spunlace Conformability
Applying electrotherapy to a moving joint (like a flexing knee) creates massive shear stress on the pad's perimeter. A standard PE foam pad possesses high rigidity; when the joint bends, the foam resists deformation, acting as a mechanical lever that forcefully pries the hydrogel off the skin (edge-lifting). The spunlace fabric in these cloth pads features a multi-directional structural yield. As the skin stretches, the fabric lattice expands harmoniously. The edge tension drops to near zero, eliminating the lever effect and ensuring 100% of the active conductive area remains anchored to the epidermis during kinetic movement.
-
Passive Vapor Transmission (Breathability)
During prolonged 60-minute therapy sessions, the covered stratum corneum naturally secretes sweat and radiates body heat. Waterproof foam pads trap this moisture, creating a localized greenhouse effect. The hydrogel absorbs the trapped sweat, over-hydrates, and loses its internal cohesive strength (turning into a slimy mess). The micropores inherent in the spunlace cloth matrix act as passive thermal exhaust vents. They allow gaseous moisture to continuously escape the boundary layer, maintaining the exact hydrogel hydration equilibrium required for repeated 20-cycle use.
-
Anti-Bleed Carbon Lamination
A critical failure mode in low-tier cloth electrodes is "gel bleed." Because the cloth is naturally porous, exposing the pads to high temperatures during maritime shipping causes the liquid humectants in the gel to migrate upward, soaking through the cloth and ruining the product. We prevent this by extruding a hydrophobic, cross-linked carbon film directly onto the fabric under precisely calibrated calender rolling. This intermediate layer seals the porosity of the Z-axis, confining the hydrogel strictly to the skin-facing side regardless of ambient warehouse temperatures.
Applications
High-Turnover Physiotherapy
Bulk-packed unbranded pads favored by large-scale clinics where patient volume necessitates cost-effective, universal conformability.
Kinematic Joint Rehabilitation
The primary choice for post-op orthopedic TENS routing over knees, shoulders, and elbows where rigid foam pads fail to maintain contact.
Dynamic Work/Wear Stimulation
Wearable pain-gating for patients who require electrotherapy while walking, working, or performing daily physical tasks.
OEM & Private Label
-
Backing Silk-Screen Printing : The white spunlace surface is an ideal canvas for OEM branding. We utilize specialized medical-grade, non-toxic elastomeric inks to print client logos, L/R placement indicators, or instructional vectors directly onto the cloth. The ink formula flexes with the fabric, preventing the logo from cracking or flaking during pad stretching.
-
Logistics Routing : Spunlace lamination and carbon extrusion operate in our China facility. High-speed multi-cavity die-cutting, automated foil pouch sealing (e.g., 4 units per pack), and carton staging execute through our Vietnam hub, navigating specific international B2B medical consumable tariffs.
Certifications
-
Cytotoxicity Cleared : Hydrogel and fabric components are evaluated against ISO 10993-5 and ISO 10993-10 endpoints to ensure prolonged topical wear without inflammatory immune responses.
-
Systems : Material tracing, ink curing, and cleanroom web cutting operate entirely under our ISO 13485:2016 and MDSAP regulatory frameworks.
FAQ
Q: Are cloth TENS pads waterproof? Can patients wear them in the shower?
A: No. Spunlace cloth is highly breathable and microporous, making it excellent for sweat evaporation but strictly non-waterproof. If the patient showers, external water will instantly penetrate the fabric backing, dissolving the hydrogel lattice and destroying the pad. For hydro-therapy or aquatic environments, clients must specify our closed-cell PE Foam or PET Film backing options.
Q: We notice some cloth pads shed white fibers when peeling them off the plastic liner. Does your cloth do this?
A: Fiber shedding (linting) is a symptom of cheap, low-density non-woven fabrics that bypass proper hydroentanglement. The friction of peeling tears the loose surface fibers. We specify high-denier spunlace that undergoes a secondary thermal calendering process to lock the surface fibers down. This yields a clean, lint-free edge that will not shed particulates into clinical environments or onto the patient's clothing.
Physiotherapy clinic networks and commercial hardware OEMs can request physical samples of spunlace cloth pads to evaluate multi-directional stretch and carbon bond integrity.
