Process

Blowing is the first step in the yarn manufacturing process. The purpose is to open, clean and mix the raw materials to lay the foundation for subsequent processing.

• Opening : Loosely pack compressed fibers to separate them from each other and reduce clumping.

• Cleaning : Use special equipment to remove impurities from raw materials, such as leaves, dust and seed residues, to ensure pure fiber.

• Mixing : Evenly mixing fibers from different sources or properties to ensure the consistency of raw materials.

Carding is the process of further straightening and carding the cleaned fibers in order to form uniform slivers.

• Fiber carding : The carding machine uses metal card clothing to card the fibers into a parallel state to further eliminate fiber agglomeration.

• Short fiber removal : Filter out short fibers and small impurities in the fiber to improve yarn quality.

• Forming slivers : The straightened fibers are gathered into slivers.

These slivers have uniformity and moderate strength and are convenient for subsequent processing.

Although the carded fiber has begun to take shape, its uniformity still needs to be improved. The drawing process is precisely to further improve the stability of the fiber.

• Merge multiple slivers : put multiple slivers into the draw frame at the same time and mix them evenly through mechanical action.

• Draft adjustment : control the draft ratio, elongate the fiber, and ensure the uniformity and fineness of the yarn.

• Form new sliver : output smoother and more uniform new sliver to improve subsequent processing efficiency.

• Fiber separation : The fibers are loosened and separated through a high-speed rotating rotary cup to keep them in a loose state.
• Fiber arrangement : Use centrifugal force to evenly distribute fibers on
  the inner wall of the rotor, ready to form yarn.
• Yarn formation : The fibers are gradually drawn into yarn and wound on the spindle to form a certain length of yarn.
