What are the two common process routes for creating a snowflake effect?

The snowflake effect in the spinning process typically follows two entirely different production routes, with the main distinction lying in *when* and *how* the "white dots" are added.

  1. Fiber Blending Process (Pre-Feeding Method)
    The millimeter-sized white short fibers (such as chopped-staple, reclaimed cotton, and reused cotton) are directly used as a "raw material," fed into the carding or combing stage alongside the main fibers. The key process involves "sealing the bottom opening and reducing drafting tension," ensuring that the short fibers remain intact—neither combed out nor pulled apart—and are ultimately embedded randomly within the yarn structure. As a result, the fabric surface features tiny white specks with softly blurred edges, resembling drifting snowflakes. This method has the advantage of requiring minimal modifications to existing equipment, making it compatible with both ring spinning and rotor spinning systems. However, a limitation is that the size of the white spots is constrained by the length of the short fibers, and the only available color option is "natural white."

  2. Yarn Bundle Composite Process (Post-Placement Method)
    The main fiber is first spun into a regular thick yarn, while the "white specks" are individually twisted into cotton knots or dyed particles. These two types of yarns are then combined during the drawing or spinning stages—either through blending in slivers, core-spun construction, or the SiroSpun process. The particles can vary in size and color, ranging from plain white to vibrant hues, and even include specially shaped polyester filaments for a three-dimensional, distinctly textured snowflake effect on the fabric surface. This method offers significant flexibility in color customization, allowing for everything from colorful snowflakes to mixed-size speckles. However, it also comes with a slight increase in production costs due to the additional steps involved in creating the particles or combining the yarns during the drawing process.
