Briefly describe the basic principle of spinning.

Primary processing: fiber raw materials are processed preliminarily before spinning to meet the requirements of spinning processing.

Selection and mixing of raw materials: rational use of raw materials to stabilize yarn quality.

Cleaning: the process of removing impurities from large groups into small pieces and bundles at the same time.

Carding: transverse connection basically eliminates single fiber with hook, and removes impurity mixing.

Combing: further combing to remove short fibers and fine impurities.

Drafting: Stretch the slender strip, straighten the fiber and remove the hook.

And mixed with a plurality of strips to improve uniformity.

Twisting: rotating and fixing the longitudinal connection between fibers and endowing them with certain physical and mechanical properties.

Winding: the transitional form of semi-finished products in each process to ensure the continuity of spinning.

What are the main spinning systems?

According to different spinning objects (fiber raw materials), spinning systems include cotton spinning, wool spinning, hemp spinning and silk spinning.

What is the initial processing of fiber raw materials?

What kind of primary processing do you have?

The primary processing of fiber raw materials is the primary processing of fiber raw materials before spinning, and removing non-fiber substances in raw materials as much as possible is beneficial to spinning processing. At present, the primary processing mainly includes cotton ginning, wool washing, (hemp) degumming and (silk) refining.
