Jinyi Nonwoven Fabric Machinery

Web Formation

Carding is the heart of the drylaid web formation process and serves as the critical foundation for producing high-quality nonwoven fabrics. As the core technology in staple fiber processing, carding transforms baled fibers—whether natural, synthetic, or specialty materials—into a uniform, coherent fibrous web that determines the fundamental characteristics of the final nonwoven product. This process essentially creates the “skeleton” upon which all subsequent bonding technologies build to impart final fabric integrity.

The core principle of carding involves mechanical fiber processing through a series of rotating cylinders and rolls covered with card clothing—specialized wire surfaces with precisely angled teeth. As fiber tufts pass between these closely spaced surfaces operating at different speeds, they undergo a series of opening, individualizing, and parallelizing actions. The carding machine progressively breaks down fiber clusters into single fibers and ultimately deposits them as a uniform thin web with controlled fiber orientation.

Jinyi Machinery offers comprehensive carding solutions through several specialized series designed for different end-product requirements:

• JY-PC Series Single-Cylinder Cards: These versatile machines feature one main carding cylinder and are ideal for producing lightweight webs for hygiene and medical applications. They offer excellent flexibility and ease of operation, delivering consistent web quality for standard nonwoven production requirements.
• JY-HC Series High-Speed Cards: Specifically engineered for demanding applications such as hydroentangling and spunlace lines, these machines feature optimized cylinder configurations and advanced doffing systems. They maintain exceptional web quality at high production speeds, making them ideal for wipes and hygiene applications.
• JY-WC Series Multi-Cylinder Cards (Tandem Cards): Equipped with advanced cylinder arrangements, these high-performance machines provide extended carding action and superior fiber blending. They deliver excellent carding and blending performance, consistently achieving high web quality on production lines. This configuration is particularly valuable when processing challenging fiber blends or when maximum throughput is required.
• JY-RC Series Random Cards: Incorporating specialized randomizing rolls that disrupt the preferential fiber orientation created by traditional carding, these machines produce webs with more isotropic properties—similar strength characteristics in all directions—which is essential for applications requiring uniform dimensional stability.

Technical Specifications
