In the prior art, in order to enable the fibers to bond to each other during heating, a binder is generally added or a sheath-core fiber (including a high-melting component and a low-melting component) is prepared. However, the preparation of sheath-core fibers has higher requirements on fiber materials and composite spinning equipment, and the conventional common adhesive usually adopts solvent adhesives, so that the pollution is strong and the toxic and side effects are large.
