Spunlace nonwoven technology has revolutionized the textile and manufacturing industries, and one of its most critical applications today is its use as a base fabric for synthetic leather, also known as faux leather or PU/PVC leather. This specialized material, often referred to as leather fabric spunlace nonwoven, provides a superior foundation that is transforming the automotive, upholstery, and fashion sectors.
This article explores the unique characteristics, core benefits, and wide-ranging applications that make spunlace nonwoven fabric the preferred substrate for high-performance synthetic leather manufacturers.
Core Characteristics and Manufacturing Excellence
The superior performance of leather fabric spunlace nonwoven stems directly from its manufacturing process.
The Hydro-Entanglement Advantage
Unlike traditional nonwovens that rely on chemical binders, the spunlace process uses high-pressure water jets to mechanically entangle fibers (typically a blend of polyester and nylon). This process achieves high strength and structural integrity without compromising the fabric’s soft drape.
The resulting material exhibits several key properties vital for synthetic leather production:
Exceptional Uniformity: The fibers are distributed evenly, eliminating weak spots and ensuring the final leather product has a smooth, consistent surface for coating.
High Purity: The absence of chemical glues means the base fabric is cleaner and free from undesirable chemical residues, which is crucial for subsequent coating processes (like $\text{PU}$ or $\text{PVC}$ application).
Dimensional Stability: The tightly entangled structure provides excellent resistance to stretching and shrinkage, ensuring the synthetic leather maintains its shape during processing and end-use.

Their commitment to quality control ensures that the dimensional stability and purity of the nonwoven base are consistent across large production volumes.
Why Spunlace Nonwoven Excels as a Leather Base
The features inherent in spunlace technology offer distinct performance advantages over older substrates like woven fabrics or needle-punched nonwovens.
Superior Physical Properties
Leather fabric spunlace nonwoven is prized for its ability to mimic the feel and performance of genuine leather.
High Strength and Durability: The mechanical entanglement ensures robust tensile and tear strength, allowing the synthetic leather to withstand the friction and stress encountered in high-traffic applications like car seats or furniture.
Softness and Breathability: The fabric has a non-directional fiber orientation and a soft hand-feel that closely resembles natural leather. Its open, porous structure provides a degree of breathability that is often lacking in standard synthetic leathers, enhancing comfort.
Excellent Coating Adhesion: The surface of the spunlace fabric offers a superior anchor for the PU or PVC coating. This excellent bond prevents delamination (the separation of the coating from the base) and extends the life of the final product.
Processing Efficiency and Aesthetics
Using spunlace as a base simplifies the manufacturing process for synthetic leather:
It reduces the need for extensive pretreatment or binding agents before coating.
It easily accepts dyeing and finishing treatments, allowing for a wider range of colors and aesthetic textures on the final PU surface.
Key Applications Transforming Global Markets
The reliability and versatility of leather fabric spunlace nonwoven have made it the go-to substrate for various high-value applications across global industries.
Automotive Interior: This is a crucial application. The spunlace base provides the necessary high durability, dimensional stability, and resistance to temperature fluctuations required for car seats, door panels, and dashboards. Its high strength ensures the upholstery remains intact under constant use.
Furniture and Upholstery: For couches, chairs, and other household items, the softness and superior coating adhesion of the spunlace base result in synthetic leather that is both comfortable and highly resistant to peeling and cracking.
Footwear and Fashion: Used in the manufacture of sneakers, boots, and handbags, the material offers a light yet strong base that can be molded, stitched, and dyed effectively, offering designers flexibility while ensuring product longevity.
Apparel and Accessories: Used in jackets, belts, and gloves, the spunlace base provides the desired combination of flexibility and structure.
Conclusion
The rise of leather fabric spunlace nonwoven represents a significant step forward in synthetic material science. Manufacturers like Changshu Yongdeli Spunlaced Non-woven Fabric Co., Ltd. are successfully leveraging this advanced base fabric to produce PU and PVC leathers that are not only more sustainable and cost-effective than natural hides but also surpass traditional synthetic alternatives in terms of comfort, durability, and aesthetic quality.
