The spinning process usually includes core processes such as opening and carding, drawing, roving, and fine yarn. The spinning machine accessories of different processes play their respective roles, jointly ensuring the quality and production efficiency of the yarn. The specific applications are as follows:
1. Opening and sorting process
The core of this process is to loosen the block fibers into small fiber bundles and remove impurities. The application of key accessories is as follows:
Comb roller: The core component on the carding machine, covered with dense comb needles on the surface, can further loosen the loose fiber pieces into a single fiber state, while combing away small impurities. It can also make the fibers initially appear in a
straight arrangement, laying the foundation for subsequent processing.
Striker: a key component of the loosening equipment, which uses the impact force generated by high-speed rotation to tear the fiber raw materials into small pieces and bundles, weakening the connection between fibers and impurities, assisting in the subsequent removal of impurities, and also achieving preliminary mixing of different fibers during the striking process.
2. Union process
This process mainly involves merging and stretching multiple combed fiber strips to improve their uniformity. The core components include:
Rubber roller and roller: The two cooperate to hold the fiber strip. The roller pulls the fiber strip at different speeds, while the rubber roller tightly adheres to the fiber strip with its own elasticity, ensuring that the fiber strip is evenly stressed during the stretching process, avoiding problems such as breakage or uneven thickness, and making the merged fiber strip uniform in thickness and structure.
Pressure rod: As an auxiliary stretching component, it can generate friction at the fiber channel, control the fiber movement trajectory, stabilize the fiber speed change point, reduce the short and uneven segments of the fiber, further optimize the dry quality of the fiber, and provide excellent semi-finished products for subsequent spinning.
3. Roving process
This process requires further stretching and thinning of the merged fiber strips, and adding a small amount of twist to roll them into coarse yarn. The core accessories are applied as follows:
Ingot wing: It is the twisting and winding core component of the roving machine, which applies twist to the fiber strips through rotation, allowing the fibers to be held together while guiding the twisted roving to be evenly wound on the roving tube. Its rotational speed and structural design directly affect the twist uniformity and winding quality of the roving.
Roller: Similar to the roller function in the drawing process, but adapted to the stretching parameters of the roving process, the fiber strip is further refined through differentiated rotation speeds of multiple sets of rollers to meet the fineness requirements of the roving, while ensuring that the fibers do not become disordered during the stretching process.
4. Fine yarn process
This is the key process of spinning, which requires stretching the coarse yarn to the target fineness and twisting it into yarn. Many core components play a crucial role here:
Spindle: The core component responsible for twisting yarn, which drives the yarn tube to rotate synchronously during high-speed rotation, ensuring that the stretched fiber strands have sufficient twist and tightly embrace the fibers to form a yarn with a certain strength. Its rotational stability directly determines whether the yarn will have quality problems such as loose or tight twisting.
Steel collar and wire ring: they work together. The steel ring provides a motion track for the steel wire ring, and the steel wire ring slides at high speed on the steel ring, guiding the yarn to be evenly wound on the yarn tube. And the weight and shape of the steel wire ring need to match the model of the steel collar, otherwise it will affect the yarn tension and easily lead to yarn breakage or poor winding forming.
Rubber ring: often combined with rollers and rubber rollers to form a stretching mechanism, the inner layer runs synchronously with the rollers, and the outer layer holds the fibers for stretching. By applying mechanical pressure, the rubber ring can increase the grip force on the fibers and stabilize the movement speed of the fibers in the floating zone. The inner patterned rubber ring can also improve the synchronization with the roller speed, further ensuring the drawing accuracy.
