Summary:The invention relates to the technical field of spinning, in particular to an anti-permeable polyamide fiber with a caterpillar skin-core structure and a preparation method. The cross section of the anti-permeable polyamide fiber is of a caterpillar structure, and the anti-permeable polyamide fiber is of a skin-core structure. The anti-transparent polyamide fiber is prepared by adopting a spinning assembly, the spinning assembly comprises a spinneret plate and a distribution plate, the bottom of the distribution plate is in sealing fit with the top of the spinneret plate, and a flow guide cavity for melt to pass through is formed between the bottom of the distribution plate and the top of the spinneret plate; the spinneret plate comprises a spinneret plate body, a plurality of spinneret cavities penetrating through the top of the spinneret plate body are formed in the spinneret plate body, caterpillar-shaped spinneret holes are formed in the bottom in each spinneret cavity, the spinneret holes comprise a plur
