Description

A soft low-twist yarn air-end spinning equipment and its textile process

Technical field

The invention relates to the field of textiles, and in particular to an air-end spinning equipment for soft low-twist yarn and its textile process.

Background technique

Air-jet spinning is a new spinning technology that uses airflow to condense and twist fibers in a high-speed rotating spinning cup and output them into yarn. It does not use spindles, but mainly relies on multiple components such as opening rollers, spinning rotors, and false twisting devices. The opening roller is used to grab and comb the fed sliver fibers. The centrifugal force generated by its high-speed rotation can throw out the captured fibers. The spinning cup is a small metal cup. Its rotation speed is more than 10 times higher than that of the detangling roller. The resulting centrifugal effect discharges the air in the cup outward; based on the principle of fluid pressure, the cotton fibers enter the airflow cup. , and form a fiber flow, which continuously moves along the inner wall of the cup.

Existing air-jet spinning equipment uses a carding roller to separate the cotton sliver fibers, and a negative pressure is formed inside the high-speed rotating rotor, which absorbs the separated cotton sliver into the spinning rotor and follows the high-speed rotation of the spinning rotor. A fiber flow is formed, and finally output into yarn under the tension of the yarn tube. A high-count air-jet spinning equipment and process with patent number 2022109500394 discloses an air-jet spinning equipment.

When existing factories perform open-end spinning, they need to prepare the cotton material into thick slivers first before using the air-end spinning equipment for spinning operations. The cotton material that has not been prepared into thick slivers cannot be directly prepared into yarn, which increases the cost. The first step will undoubtedly increase the cost of purchasing equipment and maintenance costs of the factory. Therefore, an equipment and textile process that can directly air-spun cotton materials are needed.
