China Anti Scratch And Water Spunlace Nonwoven Factories & Company

Conventional spunlace nonwovens rely on standard parallel carding and moderate hydroentanglement pressures, which leave loose fiber ends on the fabric surface. Under shear friction, these loose ends pill, ball up, and cause microscopic surface scratching on delicate goods. Changshu Yongdeli utilizes cross-lapping technology coupled with multi-stage high-pressure injector bars (reaching up to 180 bar). This locks fibers into an interwoven 3D matrix. Furthermore, an in-line thermo-calender or polymeric sizing agent seals the outer boundary layer, achieving Martindale abrasion resistance above 60,000 cycles without fuzzing.

Rather than applying continuous impermeable film membranes (such as TPU coatings), we utilize continuous pad-cure impregnation with advanced C0 (fluorine-free) water-repellent dendrimers. This creates a monomolecular hydrophobic network around each individual fiber rather than sealing the interstitial micropores. Consequently, liquid water beads up with a contact angle > 120° (AATCC 22 rating > 95), while air and water vapor pass freely through the open porous matrix.

Yes. As an integrated producer operating dyeing and sizing lines under one roof in Changshu, we offer precise spectrophotometer color-matching (spectrally verified under D65, TL84, and A light sources). For polyurethane (PU) and PVC synthetic leather backing cloth, we adjust the sizing bath solids (acrylic, polyurethane, or starch-based formulations) to produce soft, medium-firm, or rigid hand feel specifications tailored to your lamination line tension.

For standard white base spunlace fabrics, MOQs start as low as 1,000 kg. For custom-dyed, sized, printed, or functional hydrophobic/flame-retardant configurations, our standard production batch MOQ is typically 2,000 kg to 3,000 kg depending on target basis weight (GSM) and slitting widths. Custom prototype samples are dispatched within 3–5 working days, while 40-foot high-cube export container orders are completed within 15–20 business days.

Every chemical auxiliary, pigment, and raw fiber bale undergoes stringent entry screening. Our products are formulated to be free of substances on the SVHC candidate list under EU REACH regulations, free of heavy metals under RoHS 2011/65/EU, and compliant with OEKO-TEX Standard 100 Class I (baby skin contact). Third-party test reports from accredited laboratories (SGS, Intertek, or TÜV) are available upon project specification.

In addition to staple virgin polyester (PET), high-wet-modulus viscose, and polypropylene (PP), YDL processes specialty high-performance fibers including pre-oxygenated PAN filaments (flame barrier with LOI > 45%), polyimide (PI) fibers for hot-gas filtration up to 260°C, basalt rock fibers for non-combustible insulation, glass fiber nonwovens, and elastic spandex filaments for 4-way stretch orthopedic substrates.
