High-Performance Medical & Functional Substrates
Engineered hydroentangled webs specifically manufactured for medical diagnostic testing, urological barrier laminates, and clinical personal hygiene platforms.
China Factory 4.0: Supply Chain Resilience & Efficiency Advantages
Deep vertical integration eliminating multi-tier subcontractor variance, delivering real-time metric tracking, high dimensional stability, and dependable delivery schedules.
All-Under-One-Roof Processing
Unlike conventional contract converters who outsource chemical dyeing, sizing, and anti-bacterial topical application across multiple vendors, YDL Nonwovens operates an interconnected hydroentanglement, continuous drying, and functional sizing line directly in Changshu, Jiangsu.
AI-Assisted Optical Defect Detection
Online high-resolution CCD cameras continuously scan every running meter for fiber clustering, pinholes, lint slubs, and grammage deviations down to ±1.5 GSM. Sub-standard sections are automatically tagged in real time before roll slitting.
Raw Material Upstream Leverage
Positioned strategically in China’s premier textile industrial corridor, our facility leverages immediate rail and port access to high-grade virgin polyester, bamboo fiber, and Lenzing certified viscose bales, shielding contract buyers from volatile global freight surges.
Macro Industry Solutions: Precision Urinary Nonwoven Media
Custom cross-lapped matrices balancing high void volume, directional wicking kinetics, and superior rewett resistance for global clinical device manufacturers.
Acquisition Distribution Layers (ADL)
By tuning fiber denier profiles and hydroentanglement jet pressure, our urinary nonwovens achieve instantaneous fluid intake rates, rapidly dissipating urine volume longitudinally into absorbent core systems while preventing surface pooling.
Odor Neutralization & Antibacterial Control
Infused with zinc ricinoleate and broad-spectrum antimicrobial finishes, our substrates inhibit the microbial breakdown of urea into volatile ammonia gas, sustaining skin-neutral pH levels and mitigating catheter-associated skin dermatitis.
Diagnostic & Test Strip Carrier Webs
Ultra-pure, binder-free hydroentangled webs providing zero chemical leachables. Serving as structural backings and pre-filter matrixes in urinalysis dipstick applications where reagent inertness and consistent fluid flow rates are mandatory.

| Ultrasonic Hydrophobic Barrier | 100% Polypropylene (PP) | 25 - 55 GSM | 1.5 : 1 to 1.9 : 1 | Anti-leak leg cuff barrier, hydrostatic head > 350 mm |
Global Enterprise Procurement: Rigorous Compliance Safeguards
Navigating strict cross-border regulatory frameworks with complete documentation, lab batch testing, and certified biocompatibility.
ISO 10993 Biocompatibility
All medical and urinary contact nonwovens undergo rigorous cytotoxicity, skin sensitization, and intracutaneous irritation assays, validating safe prolonged skin and mucosal membrane exposure.
EU MDR & FDA Master File Dossiers
Providing technical documentation, REACH compliance certification, SVHC non-use declarations, and complete lot traceability files from fiber sourcing to container loading.
Custom Slit-Width & Core Packaging
Engineering roll lengths up to 4,500 meters with automated tension monitoring, ensuring zero web flutter or edge curling on high-speed continuous diaper and pad assembly equipment.
Technology Roadmap: Next-Generation Urinary Nonwovens
How Changshu Yongdeli is pioneering sustainable biopolymers and intelligent biosensing fabric architectures.
100% Circular Bio-Degradable PLA Webs
Deploying hydroentangled webs synthesized entirely from poly-lactic acid (PLA) and certified lyocell. Achieving 100% industrial compostability without sacrificing tensile wet strength or capillary liquid conveyance.
Smart Biosensor Substrate Integration
Formulating chemical micro-reagent finishes capable of colorimetric shift responses upon detection of elevated protein, ketone, or leukocyte markers in urine, transforming routine incontinence pads into proactive diagnostic screens.
Zero-Carbon Water-Recycling Hydroentanglement
Scaling closed-loop vacuum filtration systems that recover and sterilize 98.5% of high-pressure process water, minimizing environmental footprints across global medical product supply chains.
Functional, Technical & Eco-Friendly Nonwoven Series
Explore specialized nonwoven materials ranging from aroma-infused wipes to photo-reactive, flame-retardant, and carbon/bamboo matrices.
