The manufacturing process of conductive fiber-coated wires
2025-07-30
Mix conductive fibers (such as stainless steel fibers and carbon fibers) with base fibers (such as acrylic and cotton fibers) in a certain proportion. The conductive fibers need to be pre-treated, such as opening and impurity removal, to ensure even mixing with the base material.
The process flow for conductive fiber-coated wires mainly includes the following steps:
Raw Material Preparation
Conductive fibers (such as stainless steel fibers, carbon fibers, etc.) and base fibers (such as acrylic, cotton fibers, etc.) are mixed in a certain proportion. The conductive fibers need to be pre-treated with opening and impurity removal to ensure uniform mixing with the base material.
Spinning Process
Cleaning: After mixing the conductive fibers and base fibers, they are opened and impurities are removed by a cleaning machine to produce cotton rolls.
Carding: The mixed fibers are combed into single fibers in a carding machine, using a “multi-carding, low-speed” process to ensure uniform distribution of the conductive fibers.
Combing: Short fibers and impurities are removed, improving the straightness and parallelism of the fibers to form a combed sliver.
Drawing and Roving: The combed slivers are combined and twisted into roving.
Spinning: On a ring spinning machine, the speed difference generated by the stepped front rollers quickly wraps the outer fibers (such as acrylic) around the conductive core yarn (such as stainless steel) to form a core-sheath composite yarn.
Post-processing
After spinning, the semi-finished products need to undergo quality inspection to ensure conductive performance and structural stability.
