Spunlace nonwoven fabric — also called hydroentangled nonwoven — is a soft, textile-like sheet material produced by mechanically bonding loose fiber webs using high-velocity jets of water rather than heat, chemicals, or binders. The result is a fabric with a uniquely soft hand-feel, good drapability, and a clean surface entirely free of adhesive residues — making it the gold standard substrate for premium wet wipes worldwide.
As the global wet wipes market continues its strong growth trajectory — driven by heightened hygiene awareness, expanding baby care segments, and increased demand for medical and industrial disposable wipes — the quality, consistency, and sustainability profile of the substrate fabric have become critical differentiators for brands. Spunlace wipes fabric sits at the intersection of all these demands.
Unlike thermally bonded or chemically bonded fabrics, hydroentangled fabrics contain no foreign materials beyond the selected fibers. This purity translates into better skin compatibility, lower chemical migration risk, and greater compatibility with preservative and active-ingredient formulations in the wet wipe solution.
Understanding the manufacturing process is essential for any specifier who wants to evaluate fabric quality, interpret data sheets, and make informed purchasing decisions. Aojia Nonwoven operates two fully integrated, high-precision spunlace production lines with a working width of 3.5 metres, enabling consistent, large-format production.
Raw fibers (viscose staple, polyester, or a combination) are opened, cleaned, and blended in controlled ratios. Homogeneous blending at this stage is critical for uniform GSM and consistent performance across the roll width.
Opened fibers are combed into a fine, parallel or cross-lapped web on a moving conveyor belt. The carding step controls fiber orientation — influencing the final fabric's MD (machine direction) vs. CD (cross direction) tensile ratio.
The loose web passes under arrays of fine-diameter nozzles (typically 0.10–0.15 mm orifice diameter) injecting water jets at pressures of60–300 bar. These high-velocity streams mechanically interlock fibers without any adhesive. Multiple jet heads — each with hundreds of orifices — entangle the web progressively. Jet pressure, number of passes, and belt speed determine fabric density, tensile strength, and surface character.
Excess water is removed via vacuum extraction and through-air dryers or heated drum dryers. This step also locks in dimensional stability and, where required, sets a surface pattern from an embossed drum (pearl pattern, 3D texture).
The finished roll (up to 3,200 mm wide at Aojia's lines) is slit to customer-specified widths — from 100 mm to 3,200 mm — wound onto cardboard cores, and prepared for export in moisture-barrier packaging.
The fibers selected for a spunlace wipe substrate decisively shape its hand feel, absorbency, strength, and environmental profile. Aojia's wipes products are available in viscose (rayon), polyester, and custom blends — each with distinct performance characteristics:
A common formulation for personal care wet wipes is a 70% viscose / 30% polyester blend. The viscose dominates the soft, absorbent character while polyester provides the wet tensile strength needed to survive aggressive dispensing, wringing, and wiping without tearing. For flushable applications, 100% viscose or viscose/lyocell blends are specified to ensure the fabric disperses in wastewater systems.
The technical specification of spunlace nonwoven for wet wipes encompasses a wide range of measurable parameters. Understanding these ensures that the substrate performs correctly after saturation, packaging, and the end-user's wiping action.
Surface texture is not merely aesthetic — it influences the mechanical cleaning efficacy, liquid release behaviour, and perceived quality of the finished wipe. Aojia's wipes fabric is available in three principal surface configurations:
The flat, smooth surface of plain spunlace offers maximum skin contact area, fast liquid absorption, and a premium soft touch. It is the dominant choice for baby wipes and premium facial wipes where gentleness is paramount.
The pearl pattern is embossed on the fabric during production using an engraved drum. The raised circular elements create a subtle grip texture that improves the user's hold on the wet wipe, slightly increases the fabric's perceived thickness, and adds a premium visual cue associated with quality personal care products.
Three-dimensional or apertured spunlace variants are formed by entangling the web over a patterned mesh drum. The resulting open apertures or raised ribs increase surface roughness for mechanical cleaning efficacy, improve liquid strike-through for high-capacity wipes, and create distinctive visual differentiation on shelf.
Flushability has become one of the most scrutinised technical and regulatory dimensions in the wet wipes industry. Growing consumer confusion between "flushable" labelling and actual drain-safe performance has prompted stricter testing frameworks and increased demand for genuinely dispersible substrate materials.
True flushability requires the fabric to rapidly lose structural integrity on contact with water movement — dispersing into fibres that will not accumulate in pipes, pumps, or wastewater treatment screens. This behaviour depends entirely on fibre composition: only materials that swell and lose entanglement strength in water qualify. 100% viscose (regenerated cellulose) spunlace is the primary substrate meeting current flushability benchmarks, since the hydroentangled cellulose fibres disengage under turbulent water flow.
Beyond flushability testing, brands are increasingly required to demonstrate full lifecycle biodegradability — including in home compost conditions, marine environments, and managed landfill. Viscose-based spunlace performs well across all these environments. When combined with a plant-based or alcohol-free wipe solution formulation, the entire wipe product can qualify for eco-labelling under programmes such as the EU Ecolabel or Nordic Swan.
The single most important mechanical performance criterion for wet wipes fabric is wet tensile strength — because the fabric must withstand dispensing forces, consumer handling, and a vigorous wiping stroke while fully saturated with the wipe solution. Solutions containing alcohol, surfactants, or preservatives may also chemically plasticise the fiber matrix, slightly reducing strength versus dry testing. Fabric specification sheets should always include wet strength data at the specific saturation level of the intended wipe formula.
Lint — microscopic fiber fragments released from the fabric surface — is a critical quality criterion, particularly for medical wipes used in wound care or sterile environments, and for cosmetic wipes applied near the eyes. Lint is evaluated per EDANA WSP 40.3 by pressing the fabric against a black surface and measuring transferred fibres gravimetrically. Premium-grade medical spunlace from Aojia targets lint values below 0.5 mg/m².
