It is twisted and processed. Wherein, the liquid auxiliary bundling state means that the fiber sliver is in a liquid-assisted wetting, absorbing and bundling state of the liquid, for example, so that the fiber sliver is wetted or the fiber sliver is immersed in the liquid. In the spinning process, depending on the situation and requirements, selective liquid-assisted bundling of the pre-draw zone, the main draft zone and the twist zone can also be carried out. For example, in the pre-draw process or the main draft process, the fiber sliver is placed in a liquid auxiliary bundle state. Of course, the spinning method may also cause the fiber slivers to be in a liquid auxiliary bundling state during the pre-draw process and the main draft process. That is to say, the spinning method of the present invention only needs to ensure that the fiber sliver is in a liquid auxiliary bundling state during the twisting treatment, and further, the fiber sliver can be further in the liquid state during the pre-draw processing. Auxiliary bundling state, or in the main drafting process, the fiber sliver is also in a liquid auxiliary bundling state, and even in the pre-drawing process and the main drafting process, the fiber slivers are in a liquid auxiliary bundling state, that is, from the In the pre-draw process, the main draft process to the twisted yarn, the fiber sliver is always in a liquid-assisted, infiltrated, adsorbed and bundled state of the liquid.
