Melt blown cloth spinneret plate mold

The spinneret is also called spinning cap. The function of the spinneret is to convert the viscous polymer melt or solution through micropores into a fine flow with a specific cross-section, and solidify it through a solidifying medium such as air or a solidifying bath to form a thread.

The spinneret can be divided into:

(1) ordinary type, which can be divided into melt-spinning spinneret (its shape is round, rectangular, fan-shaped) and wet-spinning spinneret (also known as spinneret);

(2)Special-shaped spinneret, the cross-section of the spinning fiber is non-circular;

(3) composite spinneret to manufacture composite fiber.

In order to spin nanofibers, the spinneret holes are much thinner than those on ordinary melt-blown equipment. NTI can be as small as 0.0635 mm (ie 63.5 microns) or 0.0025 inches. Into a total width of more than 3 meters. The diameter of the melt-blown fiber thus spun is about 500 nm. The finest single fiber diameter can reach 200 nanometers.

Due to the small orifice of the melt-blown equipment for spinning nanofibers, if no measures are taken, the output will inevitably be greatly reduced, so NTI adopts to increase the number of orifices of the orifice, each spinneret has 3 or more rows hole. By combining many unit components (depending on the width), the output can be greatly increased during spinning. The actual situation is that when 63.5 micron holes are used, the number of holes in a single row of spinneret per meter is 2880. If three rows are used, the number of holes per meter of spinneret can reach 8640 holes, so that its output can be combined with spinning It is equivalent to ordinary meltblown fiber.
