What is a two component spunbonded spunlaced nonwoven microfiber leather substrate? In fact, the production process of bicomponent superfine fiber spunbonded spunlaced nonwoven fabrics is a combination of filament spunbonded and spunlaced nonwoven fabrics. Two types of high polymer PET/PA6 are produced at a certain composite ratio through conjugated spinning, air flow drafting, web laying, spunlaced, drying, calendering, and winding to produce a new type of nonwoven fabric. The main process is to use the spunlace stripping technology in the two-component spunbonded nonwoven fabric. The hollow orange petal shaped superfine fiber filament is spunlaced through the back channel to complete fiber opening and consolidation, forming a two-component superfine fiber spunbonded nonwoven fabric.

"The production of high-grade artificial leather using superfine fiber spunlaced nonwoven fabrics as raw materials has formed a denser and disorderly three-dimensional structure than ordinary synthetic fibers. The leather produced can achieve a degree of authenticity, and the peeling strength and folding fastness are greatly improved, overcoming the shortcomings of natural leather that are prone to mildew, odor, embrittlement, and low strength, achieving excellent properties that natural leather cannot possess." Huang Youpei said. Therefore, superfine fiber spunlaced nonwoven fabrics can meet the needs of shoe leather, luggage leather, sofa leather, automotive interior leather, and other fields, providing a good foundation and development space for clothing leather, and are an upgraded product in the application field of nonwoven fabrics.
