View SpecificationsEngineering Nonwoven Fabrics for Next-Generation Hygiene Applications
Modern hygiene goods demand strict control over chemical purity, mechanical durability, and touch softness. At Changshu Yongdeli Spunlaced Non-woven Fabric Co., Ltd. (YDL Nonwovens), our manufacturing philosophy merges hydroentanglement science with customized fiber formulation to create high-performance rolled goods for the hygiene, cosmetic, and medical sectors.
Hydroentanglement utilizes ultra-high-pressure micro-jets of recirculated, deionized water—ranging from 80 bar to upwards of 220 bar—to physically entangle carded fiber webs without the addition of chemical binders, polyvinyl alcohol (PVA), or synthetic resins. This ensures that the resultant fabric remains zero-cytotoxic, hypoallergenic, and inherently lint-free, satisfying the rigid biological evaluations mandated by international healthcare agencies.
- Cross-Lapping Web Architecture: Minimizes anisotropy, eliminating longitudinal necking during high-speed diaper and pad converting operations.
- Binder-Free Pure Bonding: Preserves fiber softness, skin biocompatibility, and instantaneous fluid strikethrough times.
- Full Lot Traceability: Continuous electronic defect inspection (optical cameras) from raw fiber bale opening to finished reel slitting.

China Integrated Manufacturing & Supply Chain Advantages
Positioned in the Yangtze River Delta industrial hub (Changshu, Jiangsu), YDL Nonwovens leverages world-class polymer ecosystems, direct port access, and unified finishing lines under one roof.
Direct Polymer & Staple Fiber Access
Direct supply contracts with upstream petrochemical producers (PET, PP) and global viscose leaders (FSC-certified regenerated cellulose, Lenzing, Sateri) guarantee competitive baseline pricing, raw material uniformity, and uninterrupted container volumes during market disruptions.
All Downstream Processes Under One Roof
Unlike factories that subcontract post-processing, YDL maintains internal web opening, high-pressure carding, hydroentanglement, continuous stenter drying, pad dyeing, functional coating, sizing, rotary printing, and precision slitting. This single-point accountability lowers lead times and prevents secondary contamination.
Rapid Logistics & Seaport Infrastructure
Located within 100 kilometers of the Port of Shanghai and Port of Ningbo-Zhoushan, finished ocean-ready containers are loaded directly from our climate-controlled warehouse, providing optimal freight schedules, reduced drayage costs, and direct export lanes to North America, Europe, Southeast Asia, and LATAM.
Meeting Global Enterprise Hygiene Procurement Demands
Enterprise procurement managers in the personal care, medical, and FMCG sectors operate under tight zero-defect tolerance frameworks. Our engineering and compliance protocols harmonize with international trade standards.
OEM & ODM Formulation Flexibility
We formulate custom fiber blends according to regional compliance needs: 100% natural viscose for European eco-label wipes, polyester/viscose blends for industrial hospital disinfectants, or PLA-infused webs for compostable top-sheets. Basis weights from 25 gsm to 200 gsm are tuned with customized aperture designs (22 mesh, 28 mesh, embossed, pearl weave).
OEKO-TEX & REACH Chemical Compliance
Every dye, chemical agent, and functional treatment (such as water-repellent fluorocarbon-free formulations, flame-retardant chemistries, or antimicrobial agents) undergoes complete toxicological screening. Our rolled goods comply with REACH SVHC limits, RoHS directives, and OEKO-TEX Standard 100 Class I (safe for infant skin).
Automated Defect & Particle Detection
Production lines are retrofitted with high-resolution line-scan CCD cameras to detect micro-contaminants, dark spots, foreign fibers, and pinholes larger than 0.5 mm in real time. Defective areas are automatically logged in roll-mapping data sheets, allowing convertors to manage line splicing without unplanned machine stops.
Localized Applications & Future Industry Trajectories
From flushable bio-substrates answering the European Single-Use Plastics Directive to electrostatic hospital filtration webs, our nonwoven platforms align with shifting consumer demands and regulatory frameworks.
Clinical & Personal Hygiene Scenarios
Feminine Care Top-Sheets: Engineered apertured spunlace webs allow viscous menstrual fluids to pass directly into absorbent core substrates (SAP/fluff pulp) without surface re-wetting, protecting delicate skin from irritation.
Baby & Sensitive Skin Wipes: Utilizing soft, cross-lapped 100% viscose or bamboo fibers, our wipe substrates provide water retention, soft dermal feel, and chemical inertness to balance water-based lotions.
Hospital Infection Control: Hydrophobic polyester/cellulose barrier spunlace used in surgical gowns and drape perimeters prevents liquid strike-through of blood-borne pathogens while maintaining breathable comfort.
Sustainable Trends: Plastic-Free Transition
EU SUPD-Compliant Solutions: With tightening global legislation on synthetic wipes, our R&D focus is accelerating bio-degradable, flushable webs combining short-staple Lyocell and natural cotton without microplastic shedding.
Low-Carbon Circular Fibers: We offer certified Post-Consumer Recycled (rPET) spunlace options for industrial wipes, insulation, and automotive backing, reducing virgin crude reliance without compromising tensile parameters.
High-Speed Multi-Jet Efficiency: Next-generation high-pressure filtration manifolds optimize water recycling, reducing energy consumption per metric ton of spunlace roll goods by 22% compared to historical baselines.

View SpecificationsProcurement & Engineering Frequently Asked Questions
Key information regarding production minimums, physical testing methods, biological hygiene safety, and supply chain timelines for OEM purchasers.
What is the standard MOQ and container loading volume?
For custom production runs of specified fiber ratios, our standard Minimum Order Quantity (MOQ) is 1,000 kg for in-stock trial fibers and 3,000 kg for custom-dyed or functional blends. A standard 40-foot High Cube (40' HQ) container typically accommodates between 10,000 kg and 14,000 kg of hydroentangled roll goods, depending on compression parameters and roll diameter.
How is parallel-laid spunlace distinguished from cross-lapped spunlace?
Parallel-laid spunlace directs carded fibers in the machine direction, providing high MD tensile strength but lower cross-direction (CD) stability (often a 4:1 or 5:1 ratio). In contrast, cross-lapped spunlace folds carded webs diagonally, generating near-isotropic tensile strength (close to 1:1 or 1.5:1 ratio), preventing elongation or distortion during high-speed hygiene converting.
Can you provide batch-level Certificate of Analysis (COA) data?
Yes. Every batch roll shipped is accompanied by an inspection report certifying Grammage (GSM) under ISO 9073-1, MD and CD Tensile Breaking Force and Elongation under ISO 9073-3, Liquid Absorbency Capacity and Rate under ISO 9073-6, plus bioburden testing documentation confirming bacterial colony count < 100 CFU/g for medical-grade rolls.
How does your mill address bioburden and hygiene safety?
Our hydroentanglement clean-lines use closed-loop multistage water purification, which eliminates microbial vectors, biological biofilms, and particulate minerals. Reels are dried at temperatures exceeding 130°C and undergo continuous online optical inspection before being shrink-wrapped in heavy-gauge polyethylene packaging to prevent ingress during sea transit.
