Description
Technical Field
[0001] The utility model relates to the technical field of composite high-elastic non-woven fabrics, in particular to a spinneret structure. Background Art
[0002] Nonwoven fabric is a kind of non-woven fabric, which is made of high polymer chips, short fibers or fibers through air flow or mechanical web, and then reinforced by spunlace, needle punching or hot rolling to form non-woven fabric. Since traditional nonwoven fabrics have weak elasticity, high-elastic nonwoven fabrics made by spinning composite raw materials through spinnerets and then through web forming, spunlace and other steps can overcome the disadvantage of low elasticity. However, due to different production lines and scales, the existing nonwoven fabrics use spinnerets with circular or rectangular structures, but the spinnerets are difficult to be suitable for both circular or rectangular installation positions, and only a single device can match the spinneret; the silk threads sprayed by the spinneret are either circular or triangular, but the spinneret is difficult to meet the requirements of both circular and triangular spraying. Summary of the invention
