product details
Introduce our products
A fine-surface polyurethane synthetic leather with controlled low-luster finish and compression-set resistance, engineered for applications requiring sustained tactile softness under repeated loading. Constructed on a high-density microfiber nonwoven with an aliphatic PU topcoat, the material delivers peel adhesion ≥18 N/3cm and maintains surface integrity through 50,000 Bally flex cycles at both ambient and sub-zero conditions. Solamni provides full color development services with 24-hour sample response and REACH/RoHS documentation per shipment.

Solamni operates an ISO 9001:2015-certified in-house laboratory. Validation protocols for smooth soft grain microfiber PU leather address surface uniformity, tactile consistency, and mechanical durability for apparel and contact applications.
Surface Uniformity & Tactile Consistency:
Surface Profilometry: Surface roughness measured using a contact profilometer, with Ra (arithmetical mean roughness) values maintained within ±8% tolerance across the full roll width. The fine grain structure is mechanically embossed, not surface-printed.
Hand-Feel Validation: Shore A hardness (ISO 7619-1) and compressibility measured to ensure consistent softness across batches. Silicone-free surface treatment ensures compatibility with subsequent coating and lamination processes.
Gloss Control: Specular gloss measured at 60° per ISO 2813; each batch verified against approved standard for consistent matte finish.
Mechanical & Durability Testing:
Tensile & Tear Performance: Validated per ISO 13934-2 and ISO 13937-2 using Universal Testing Machine. The microfiber nonwoven substrate delivers balanced warp/weft strength with minimal anisotropy.
Peel Strength: Coating-to-substrate adhesion per GB/T 8949; acceptance ≥18 N/3cm. Low peel values indicate inadequate interfacial bonding.
Abrasion Resistance: Martindale per ISO 12947-2 at ≥50,000 cycles under 9 kPa pressure. Post-test inspection verifies surface fiber raising, pilling, and grain retention.
Flex Resistance: Bally flex per ISO 5402-1 at both ambient (50,000 cycles) and sub-zero (-10°C) conditions.
Pilling Resistance: Evaluated per ASTM D3512 using random tumble pilling tester; acceptance Grade 4 or higher, ensuring the soft surface does not develop unsightly pills or fuzz balls during use.
Environmental & Chemical Validation
Hydrolysis Aging: Jungle test per ASTM D3690 at 70°C / 95% RH for 36+ months.
Restricted Substances: Third-party GC-MS and ICP-MS screening for REACH SVHC, RoHS, and phthalates (6P/7P Free).
Formaldehyde Content: Verified below 20 ppm per ISO 17226-2.
Azo Dyes: Tested per ISO 17234-1, acceptance below 30 ppm for each restricted aromatic amine.
Low VOC: Water-based PU formulation minimizes volatile organic compound emissions.
Industrial Application Scenarios
Apparel & Garments: Applied in fashion jackets, skirts, trousers, and performance wear where a soft, pliable material with a premium tactile feel is required. Suitable for direct skin contact applications due to the fine-grain surface and non-irritating texture.
Footwear & Accessories: Optimized for sneaker uppers, casual shoe panels, boot linings, and bag exteriors requiring a smooth, refined surface appearance. The soft grain structure provides a premium aesthetic without compromising stitch-tear strength.
Furniture Upholstery: Used in residential sofas, headboards, ottomans, and occasional chairs where tactile comfort and visual refinement are primary considerations. Suitable for light to medium-traffic residential settings.
Automotive Interiors: Applied in car seat upholstery, armrests, headliners, and door panel inserts where a soft-touch surface enhances passenger comfort.
Packaging & Display: Suitable for luxury packaging, jewelry boxes, bookbinding, and display cases requiring a refined, elegant surface texture with consistent appearance.
FAQ
Q:What is the difference in surface abrasion resistance between 0.8mm and 1.2mm thickness grades?
Q:Can silicone-based surface treatments be applied for additional softness without affecting subsequent lamination?
Q:How does the smooth fine-grain surface behave under automated cutting compared to embossed textures?
Smooth fine-grain surfaces provide consistent friction against cutting tables and nesting dies, enabling precise registration and cut-edge clarity. This translates to approximately 2-3% higher cutting yield compared to heavy-textured surfaces where die slippage occurs.
