Standard for Rotor Spinning Machines and Wipers Made in Japan

Standard of rotor spinning: the main task of this process, the production index of groups and individuals, the basic content of working methods of this type of work and the grading standard of operation technology, and the relevant technical regulations of spun varieties. Five, the types and causes of defects in the previous process, prevention methods and their influence on the next process, the basic knowledge of production technology in the spinning department, as well as the safety operation procedures and fire protection knowledge of this type of work.

Joining, reversing, changing strips, cleaning, preventing defects and ensuring quality.

1, carding, impurity removal, twisting and winding forming: carding: carding the fed sliver into a single fiber state by a serrated carding roller.

2. Impurity removal: the air spinning machine is equipped with an impurity removal mechanism, which removes impurities from the sliver while carding the sliver into a single fiber state by the carding roller.

3. Drafting: The drafting of air spinning machine is different from the roller drafting of roving and spinning. It is characterized in that the feeding roller slowly feeds the sliver, and the sliver is combed into a single fiber and accumulated in the spinning machine, and then the fiber bundle twisted by the spinning cup is drawn by the speed difference between the feeding roller and the drawing roller.

4. Twisting: Under the condition that the spinning rotor rotates at a high speed, appropriate twist is added to the yarn to make it have a certain strength, so that it can be processed in the next process.

5. Winding forming: the yarn drawn by the yarn guide roller is guided by the forming mechanism and wound into a package, which is convenient for subsequent processing, transportation and storage.
