摘要： An elastic fibre dry spinning mechanism and a maintenance control method for a spinning assembly. The elastic fibre dry spinning mechanism comprises: a spinning assembly (1), comprising a temperature control portion (13) and a spinneret portion (14) detachably overlapped with each other; and a rotary movement control portion, used for allowing the spinning assembly to lift and drop, move horizontally and rotate around the horizontal movement direction, so as to change the facing direction of the spinning assembly into a facing direction facilitating the maintenance of the spinneret portion. The spinning mechanism and the maintenance control method therefor achieve convenient, quick and efficient maintenance such as online replacement of a spinneret portion.

摘要： A spinning pack for dry-wet spinning is provided with a spinneret having not less than 6,000 spinning holes and having an aspect ratio Ra of not less than 2.5 for a spinning hole array of the spinning holes. In a device and method for producing a fiber bundle, a drawing angle of single fibers formed by the single fibers and a spinneret surface of a spinneret is in a range from 87° to 92°, the single fibers being fibers discharged from the outermost spinning holes located in the long side direction of the spinneret and running to a fiber bundle diverting guide provided in a coagulation bath. Further, a drawing angle of single fibers formed by the single fibers and the spinneret surface of the spinneret is in a range from 83° to 87°, the single fibers being fibers discharged from the outermost spinning holes located in the short side direction of the spinneret and running to the fiber bundle diverting guide provided in the coagulation bath.

摘要： The invention relates to a device for melt-spinning synthetic filaments, comprising a spin-die manifold for holding at least one bank of spinnerets and heating means for heating the bank of spinnerets. At least one spinneret with second heating means for heating the spinning pump is allocated to the bank of spinnerets and the spinning pump and bank of spinnerets are interconnected by a melt line. To achieve the most user-friendly arrangement possible for the bank of spinnerets and the spinning pump, said pump and the second heating means are held by a separate pump support which is placed at a distance from the spin-die manifold. This allows the spinning pump to be heated independently of the spin-die manifold.

摘要： The invention relates to a spinneret for spinning thermoplastics. Said spinneret comprises a central polymer inlet channel, a filter assembly (2), consisting of one or more filter plates of various filtration grades, a spinneret plate (3) and a housing (1) which receives and tightly surrounds the filter assembly (2) and the spinneret plate (3). The selection of suitable materials and tolerances for the individual parts of the spinneret enables the sealing effect to be achieved at operating temperature by the increased expansion of the internal components, in relation to the external housing.

摘要： The invention relates to a spinneret of a very specific geometry which provides more strength compared with the commonly applied spinnerets, and to a spinneret made of a specific metal alloy which also provides a further high strength. In combination, a spinneret is resistant to spinning pressures up to 60.000 kPa if it is made of the specific geometry and made of the preferred metal alloy of gold, platinum, rhodium and palladium, which does not comprise contaminations and which material is very homogeneous and thus does not show an obvious second phase.
