What is it and what does it do?

Imagine you have a tangled ball of yarn or a clump of cotton. A carding machine is like a super-precise “comber” for fibers. Its main job is to take the opened and blended fibers from the previous machines (like the bale opener and blending hopper) and align them into a continuous, thin web or sliver.¹

Think of it like carefully brushing your hair to remove knots and make the strands lie smoothly in the same direction. The carding machine does this for the tiny fibers, making them organized and ready for the next steps in the non-woven process.

How is it done?

Carding machines use a system of rotating cylinders and surfaces covered with very fine teeth or wires.² Here’s a simplified explanation:

1. Feeding: The loosened fibers are fed into the carding machine, usually in the form of a continuous lap (a sheet of loosely matted fibers).
2. Carding: The fibers pass through a series of rotating cylinders or flats covered with these fine teeth.³ These teeth work like tiny combs, gently teasing the fibers apart, removing any remaining clumps or tangles, and aligning them in the same direction.⁴
3. Web Formation: As the fibers are carded, they form a thin, delicate web of parallel fibers.⁵ This web can be further processed or condensed into a thicker strand called a sliver.⁶
4. Delivery: The carded web or sliver is then delivered out of the machine, ready for the next stage of the non-woven manufacturing process.⁷

Use in the Non-Woven Sector

Carding machines are essential in non-woven manufacturing because:

1. Fiber Alignment: They create a uniform, aligned fiber structure, which is crucial for the strength, evenness, and overall quality of the final non-woven fabric.⁸
2. Web Formation: The carded web is the foundation for many non-woven products. It can be used as is or further processed into different types of non-woven materials.
3. Improved Properties: By aligning the fibers, carding improves the web’s tensile strength, tear strength, and other important properties.⁹
4. Versatility: Carding machines can process a wide variety of fibers, including natural fibers (like cotton) and synthetic fibers (like polyester and polypropylene), making them suitable for various non-woven applications.¹⁰

Think of it this way:

Imagine you’re making felt. You start with a pile of wool fibers. You need to comb and align those fibers before you can felt them into a fabric. The carding machine is like a mechanized, highly efficient “wool comber” in the non-woven industry.

In short, the carding machine is a critical step in transforming opened and blended fibers into a well-organized web or sliver, which is the basis for many non-woven products.¹¹ It’s all about achieving the perfect fiber alignment for the desired properties and performance of the final non-woven material.
