In order to achieve the above object, the utility model provides a kind of square doughnut, it is characterized in that, and be that L shaped part forms by two cross sections, two described cross sections are that L shaped part is interconnected to form square structure.
The utility model also provides a kind of above-mentioned square doughnut spinnerets used of producing, and comprises spinnerets main body, in described spinnerets main body, has multiple spinneret orifices, it is characterized in that, described spinneret orifice is made up of two L shaped holes that are oppositely arranged.
Preferably, described L shaped hole length of side is 0.04～0.10mm; Another of L shaped hole length of side is 0.04～0.10mm, and width is 0.001～0.009mm; The outer wall of the coupling part on the both sides in L shaped hole forms one section of 1/4 circular arc, and the radius of this section of circular arc is 0.001～0.009mm, and the inwall of the coupling part on the both sides in L shaped hole forms one section of 1/4 circular arc, and the radius of this section of circular arc is 0.001～0.009mm.
Preferably, the minimum range between described L shaped hole is 0.001mm-0.008mm.
Preferably, between the both sides in described L shaped hole, angle is 90 °.
Preferably, described spinneret orifice, centered by the spinnerets center of circle, radially distributes in spinnerets main body.
Compared with prior art, good effect of the present utility model is:
The fiber cross section shape that spinnerets of the present utility model spinned the out hollow that is square, the fabric that square fiber surface structure can make fiber prepare has arranges effect closely, can play the function of windproof and rain proof in reality is used; There is hollow structure inside, hole, has improved the warming moisture-absorbing physical characteristic of fiber, can be widely used in civilian clothes, sportswear, medical supplies etc., has a extensive future.The regular easy processing of spinnerets spinneret pore structure of the present utility model, has reduced production cost.
