What is spunlace nonwoven fabric?

Spunlace (hydroentangled) nonwoven is made by carding staple fibers into a web and bonding them with high-pressure water jets instead of chemical binders or heat. The result is a soft, drapeable, low-lint fabric with good tensile strength, widely used in medical, wipes, beauty and synthetic leather applications.

Which fibers can YDL Nonwovens process?

YDL purchases and processes polyester (PET), viscose/rayon, polypropylene (PP), polylactide (PLA) and other fibers, as well as specialty fibers such as glass fiber, basalt, polyimide and pre-oxidized filament for technical and high-temperature applications.

Can color, hand feel, pattern and function be customized?

Yes. YDL runs base fabric production plus dyeing, sizing, printing and functional finishing in-house, so color, hand feel, printed pattern and functional effects such as water repellency, flame retardancy, cooling or thermochromic finishing can be matched to the buyer's specification.

Is YDL Nonwovens ISO 9001 certified?

Yes. YDL operates an ISO 9001 quality management system with documented quality control procedures from fiber intake to finished roll inspection.

Where is YDL Nonwovens located and which markets does it serve?

YDL is located in Changshu, Jiangsu Province, China, and has served global buyers since 2007 in medical and hygiene, beauty and skincare, faux leather, home textile, cleaning and filtration markets.

Single-Facility Production: Opening, Weaving, Functional Finish

In the global Personal Protective Equipment (PPE) landscape, non woven coveralls represent the critical junction between operator safety and ergonomic wearability. Operating from our manufacturing base in Changshu, Jiangsu Province, YDL Nonwovens (Changshu Yongdeli Spunlaced Non-woven Fabric Co., Ltd.) provides an integrated supply chain model. From high-purity virgin polymer selection to continuous carding, cross-lapping, high-pressure water jet entanglement, and chemical immersion or spray treatments, every variable is calibrated under strict quality controls.

Advanced Web Uniformity

Utilizing high-pressure multi-stage hydroentanglement systems, our webs achieve uniform fiber distribution without binders, optimizing cross-directional (CD) to machine-directional (MD) tensile ratios for exceptional seam integrity in finished coveralls.

In-House Chemical Finishing

Unlike standard converters dependent on third-party finishers, our facility runs continuous pad-dry-cure and functional spray operations for anti-static (surface resistivity 10⁸–10¹⁰ Ω), flame retardancy, and fluid repellent barriers.

Cost-Resilient Raw Sourcing

Direct supply contracts with premium domestic polyester (PET), polypropylene (PP), and renewable PLA fiber producers insulate our global procurement partners against market price shocks, ensuring rapid sample iteration and scaled lot production.

Strategic Procurement

Global Enterprise Demands & Industry Macro-Trends

Analyzing key shifts in industrial supply chains, cleanroom governance, and ESG mandates.

Demand for Dual-Standard Convergence

Global procurement offices increasingly mandate single coverall SKUs that satisfy both European CE certifications (EN Standards) and North American ANSI/NFPA specifications, eliminating redundant inventory allocations across distribution channels.

Circular Nonwovens & PLA Integration

Environmental policies such as the EU Corporate Sustainability Due Diligence Directive are driving corporate buyers toward biodegradable Polylactic Acid (PLA) and recycled rPET webs that minimize microplastic shedding during industrial incineration.

Supply Chain Audits & Lot Traceability

Enterprise sourcing protocols require end-to-end digital roll traceability. Each batch must include certified test reports covering filtration efficiency (BFE/PFE), hydro-head ratings, seam shear resistance, and zero cytotoxic leaching.

Regulatory Framework

Localized Compliance & Regulatory Alignment

Facilitating seamless market clearance across North America, Europe, the Middle East, and Asia-Pacific.

European Union (CE MDR / PPE)

Comprehensive technical documentation for PPE Regulation (EU) 2016/425 (Category III protection), supporting our OEM conversion clients with accredited notified body certification files.

North American (OSHA / FDA)

Formulations adhering to OSHA 1910 Subpart I and 510(k) fluid-resistant testing (ASTM F1671), ensuring zero phthalate additives and low VOC emission profiles in enclosed industrial cleanrooms.

Customs Documentation Support

Factory QA & Technical FAQ

Frequently Asked Technical Questions

Clear, unvarnished guidance on fiber chemistry, regulatory audits, and roll goods engineering for purchasing directors.

What sets hydroentangled spunlace coverall fabrics apart from standard SMS or spunbond materials?

Spunlace fabrics bond staple fibers mechanically using high-velocity deionized water needles rather than thermal bonding or latex adhesives. This creates an exceptionally soft, drapable substrate with near-zero chemical off-gassing and superior tear resistance. In coverall construction, spunlace serves as an optimal substrate for breathable lamination, providing high tensile stability at sewn seams without shedding lint.

Can YDL Nonwovens customize antistatic and flame-retardant (FR) properties in a single roll good?

Yes. Through our integrated chemical finishing lines, we perform multi-bath or pad-dry-cure applications. We can combine non-migratory antistatic agents (achieving surface resistivity down to 10⁸ ohms per square according to EN 1149-1) with durable organophosphorus flame-retardant chemistries (meeting EN ISO 14116 Index 1 criteria) without degrading fabric hand feel or seam weldability.

How does your mill guarantee lot-to-lot consistency across large-volume export orders?

Our ISO 9001 quality framework incorporates real-time radiometric beta gauges for continuous basis weight tracking across machine and cross directions. In-line machine vision cameras monitor roll surfaces for defects at 0.5mm resolution. Each slit roll is tagged with a digital barcode tracing back to specific raw fiber bale lots and finishing chemical batches.

What are the standard lead times for custom functional spunlace trial lots and full 40' HQ containers?

Standard prototype hand sheets and sample yardage (20–50 meters) are dispatched within 5 to 7 business days. Full industrial trial rolls (500–1,000 kg) typically require 10 to 14 days. Full container load (40' HQ) production runs standard at 20 to 25 calendar days, supported by direct container staging from our Changshu plant to Shanghai Port.

Which fiber blends are available for biodegradable or sustainable cleanroom coverall applications?

We offer 100% certified Polylactic Acid (PLA) spunlace, 100% Lyocell/Viscose webs, and specialized PLA/Viscose blends. These cellulosic and bio-based fibers achieve complete industrial compostability according to EN 13432 and ASTM D6400, while preserving the low-linting and tensile metrics required for critical environment cleanrooms.

Can roll widths and master roll diameters be adapted to automated high-speed ultrasonic cutting lines?

Yes. Our high-precision slitting-rewinding equipment handles finished widths from 50 mm up to 3,200 mm with edge tolerances within ±1.5 mm. Outer roll diameters can be wound up to 1,200 mm on heavy-duty 3-inch or 6-inch reinforced cardboard or plastic cores, optimized for high-speed automated PPE unwinding equipment.
