Abstract
The utility model discloses a trilobal profile spinneret with high hollow ratio and good bulkiness, which comprises a trilobal profile spinneret body provided with a central spinneret orifice, the periphery of the central spinneret orifice is provided with three long spinneret orifices in a radial shape, the distances from the farthest ends of the three long spinneret orifices to the center of the central spinneret orifice are different, the central spinneret orifice and the three long spinneret orifices are not connected, and the length-diameter ratio of the central spinneret orifice and the three long spinneret orifices is 2 to 2.5. The utility model is applicable to the spinning of the hollow fiber.
Description
Technical field
The utility model relates to a kind of spinnerets that is used for spinning, relates in particular to a kind of spinneret orifice and is the spinnerets that trilobal cross distributes.
Background technology
Because the vertical face of traditional nylon fibre long filament is straight smooth, the cross section is rounded, be mainly used in traditional garment materials such as quilt cover, cheongsam, though by technological transformation to production process, solved from thick dawn-technological problemses such as thin dawn, can produce slim lining, but this kind facing fabric deficiencies such as wearing next to the skin the not good and perspiration discharging performance difference of high humidity, comfortableness can't be overcome, thereby high-grade fabric processing can't be applicable to.In order to improve the performance of nylon fibre long filament, manufacturer develops a kind of doughnut long filament, but since in the production technology to the having relatively high expectations of spinnerets, cause the hollow rate of fiber can't reach desirable effect.
The utility model content
The technical problems to be solved in the utility model provides a kind of hollow rate height, trilobal cross profile spinneret that bulking intensity is good.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises body, described body is provided with the center spinneret orifice, it is characterized in that described center spinneret orifice periphery is provided with three long spinneret orifices radially, described three long spinneret orifice distal-most end have nothing in common with each other to the distance at spinneret orifice center, center, are not connected between described center spinneret orifice and the long spinneret orifice.
As preferably, described center spinneret orifice is 2～2.5 with the draw ratio of long spinneret orifice.
The utility model compared with prior art has obvious advantage and beneficial effect:
1, hollow rate height.Because the utility model adopts the design that is not connected between porous combination, hole, wire vent pressure and variation of temperature reach the automated closed-loop purpose when relying on shaping, can effectively improve the hollow rate of fiber.
2, bulking intensity is good.The utility model adopts the inconsistent design of length of long spinneret orifice, and what make the fiber made is polygon irregular, can effectively improve bulking intensity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: preferred embodiment one: comprise body 1, body 1 is provided with center spinneret orifice 2, spinneret orifice 2 peripheries in center are provided with three long spinneret orifices 3 radially, three long spinneret orifice distal-most end have nothing in common with each other to the distance at center spinneret orifice 2 centers, be not connected between center spinneret orifice 2 and the long spinneret orifice 3, center spinneret orifice 2 is 2 with the draw ratio of long spinneret orifice 3.
Preferred embodiment two: comprise body 1, body 1 is provided with center spinneret orifice 2, spinneret orifice 2 peripheries in center are provided with three long spinneret orifices 3 radially, three long spinneret orifice distal-most end have nothing in common with each other to the distance at center spinneret orifice 2 centers, be not connected between center spinneret orifice 2 and the long spinneret orifice 3, center spinneret orifice 2 is 2.2 with the draw ratio of long spinneret orifice 3.
Preferred embodiment three: comprise body 1, body 1 is provided with center spinneret orifice 2, spinneret orifice 2 peripheries in center are provided with three long spinneret orifices 3 radially, three long spinneret orifice distal-most end have nothing in common with each other to the distance at center spinneret orifice 2 centers, be not connected between center spinneret orifice 2 and the long spinneret orifice 3, center spinneret orifice 2 is 2.5 with the draw ratio of long spinneret orifice 3.
Claims (2)
1, a kind of trilobal cross profile spinneret, comprise body, described body is provided with the center spinneret orifice, it is characterized in that described center spinneret orifice periphery is provided with three long spinneret orifices radially, described three long spinneret orifice distal-most end have nothing in common with each other to the distance at spinneret orifice center, center, are not connected between described center spinneret orifice and the long spinneret orifice.
