Few advanced materials have expanded as rapidly — or as quietly — as spunlace nonwoven fabric. Once confined to niche medical and industrial uses, hydroentangled nonwoven is now woven into the fabric of daily life: the face mask sheet soaking in essence on a bathroom shelf, the antibacterial wipe in a hospital ward, the plush lining of a car's headliner, and the durable substrate beneath a premium synthetic leather sofa.
Global demand for spunlace nonwoven is growing at a projected CAGR of approximately 7–9% through 2030, driven by the convergence of hygiene awareness, cosmetics innovation, sustainable packaging trends, and tightening medical standards. At the center of this expansion stands a sophisticated manufacturing ecosystem — and choosing the right spunlace nonwoven manufacturer matters enormously for product quality, compliance, cost efficiency, and supply chain resilience.
This guide explores the complete technical and commercial landscape: how spunlace fabric is made, how it is specified, which applications demand which properties, and what distinguishes leading manufacturers like Zhejiang Aojia Nonwoven Technology Co., Ltd. from commodity producers.
The process begins with raw fiber selection — typically viscose (rayon), polyester (PET), wood pulp, lyocell (Tencel), or blends thereof. Fibers are opened, cleaned, and blended to the specified ratio before being fed into a carding machine. The carding process aligns or randomizes fibers into a continuous, uniform web. Web formation method determines the directional properties of the finished fabric:
Before the fiber web reaches the main entanglement zone, it passes through a pre-wet section where vacuum suction removes trapped air pockets. This ensures the high-pressure water jets penetrate the web uniformly rather than "bouncing off" air pockets — a critical step for consistent entanglement depth and fabric integrity.
In the hydroentanglement zone, the web passes over a perforated drum or flat belt while fine nozzle strips — each with orifice diameters of 0.10–0.15 mm spaced 0.5–1.0 mm apart — deliver focused water jets at pressures from 30 to 200 bar. The jets force fibers to mechanically interlock around each other. Multiple jet passes (typically 2–6 passes, alternating on each face) achieve increasing fiber cohesion, tensile strength, and surface smoothness.
After hydroentanglement, the water-saturated fabric is dewatered by suction and then passed through a through-air dryer or cylinder dryer to reach the target moisture content (typically below 8% for packaging). Post-processing options available from leading manufacturers include: calendering (heat/pressure for surface smoothing), embossing (pearl pattern, jacquard, wavy texture), printing, functional coating application, slitting, and conversion to finished rolls or cut sheets.
The fiber selection decision is the single most consequential technical choice in spunlace product development. Aojia Nonwoven's manufacturing capability encompasses all major fiber types, enabling precise customization for each end-use:
The cosmetology product line is arguably the most technically demanding in the spunlace sector. Skin-contact applications require compliance with ISO 10993 biocompatibility standards and rigorous testing for residual chemicals, heavy metals, and fluorescent brighteners (which must be zero-detectable in baby and sensitive-skin products).
Facial Mask Cloth: Typically produced from 100% lyocell or viscose at 35–55 GSM. The wet-laid or spunlaced structure must deliver tight, uniform serum distribution across the face — meaning excellent capillary wicking uniformity is as important as total absorbency. Serum retention under gentle compression (simulating face contact) is measured by the "retention ratio after centrifuge" test method.
Face Towels: At 60–80 GSM, reusable face towels require good wet tensile strength (to withstand repeated laundering at 60°C), fast drying behavior, and lint-free surface quality. The standard measurement is the ISO 9237 air permeability test alongside Martindale abrasion resistance.
Depilatory Cloth: Engineered for a specific controlled surface roughness that ensures uniform adhesion of wax strips without air pockets or edge lifting. Surface texture is created through the embossing calendar during post-processing, with Ra (average surface roughness) values specified to micron tolerances.
The global wet wipes market exceeded USD 14 billion in 2025 and continues to expand, with spunlace nonwoven being the substrate of choice for premium and professional applications. The Aojia wipes series addresses the full spectrum.
Wipes substrates must meet several simultaneous demands: hydrophilic surface treatment (contact angle typically below 20°) enabling rapid liquid absorption; wet tensile strength sufficient to resist tearing during use (typically ≥15 N/5 cm in MD direction); low linting to prevent residue on cleaned surfaces; and compatibility with preservative systems used in the wetting formulation.
Wavy-Textured Spunlace Kitchen Wipes: A standout product that illustrates the potential of surface engineering in nonwoven development. The wavy or ridged texture is produced via a specifically profiled embossing roll that creates mechanical scrubbing channels, increasing effective cleaning surface area by 30–50% compared to a flat structure, while maintaining the gentle absorbency of the spunlace substrate.
The medical spunlace segment demands the most stringent quality infrastructure. Manufacturing must take place under controlled environment conditions, with rigorous incoming material qualification and in-process monitoring.
Wound Dressings: The wound contact layer must achieve a sterility assurance level (SAL) of 10⁻⁶ or better. Fabric construction must balance two competing requirements: high absorbency to manage wound exudate, and minimal adherence to prevent wound bed disruption on removal. Low-adherence wound contact layers are frequently produced from hydrophobically treated polyester or silicone-coated viscose spunlace.
Face Mask Cloth (Medical Grade): Surgical and respirator mask substrates require validated particulate filtration efficiency (PFE) and bacterial filtration efficiency (BFE) testing per EN 14683 and ASTM F2100. Breathability is measured by differential pressure (ΔP) per unit area — balancing filtration efficiency against wearability.
The home improvement series demonstrates the versatility of polyester-dominant spunlace in architectural and interior applications. These products must satisfy demanding physical durability requirements while maintaining aesthetic qualities.
Wall Cloth: Used as a decorative or reinforcing layer on interior walls, wall cloth spunlace must exhibit excellent dimensional stability under adhesive application, resistance to humidity-induced expansion/contraction, and zero fiber shedding that could penetrate paint layers. Weight range is typically 50–120 GSM with polyester content of 80% or higher.
Curtain Fabric: Commercial-grade nonwoven curtain material offers UV-resistance and optional flame retardancy treatment compliant with EN 13773 — the European standard for textile flame spread behavior. The drapability of spunlace (its ability to hang naturally without stiffness) is quantified by the Kawabata Evaluation System (KES-F) bending rigidity value.
The base cloth series represents some of the most technically complex nonwoven products, serving industrial substrate applications where the nonwoven is not the end product but the structural foundation of a composite.
Leather Base Fabric: The substrate for PU or PVC synthetic leather must endure the coating and embossing process (temperatures up to 180°C, pressures up to 400 kN/m²) without dimensional change or delamination. Key technical metrics include: peel strength between nonwoven and coating layer (typically ≥30 N/cm), MD/CD tensile ratio (preferably below 1.5 for isotropic behavior), and surface uniformity measured by optical profilometry.
Car Roof Lining Fabric: Automotive OEMs impose among the most stringent specifications in the entire nonwoven industry. This substrate must meet:
The wiping cloth series, centered on pulp cleaning cloths, addresses the industrial and professional cleaning sector. Wood pulp / polyester composite spunlace combines wood pulp's outstanding absorbency (up to 10× own weight) with polyester's mechanical durability in a single structure. The co-form production process — where wood pulp fluff is pneumatically injected into the fiber web during web formation — distributes pulp particles uniformly throughout the nonwoven matrix for consistent performance across the full area of each wipe.
