Abstract

The utility model provides a heavy denier round hollow fiber spinneret plate. The hole shape of the spinneret plate is of a cirque shape; a gap is arranged on the cirque; the gap size of the cirque is between 0.2 and 0.4mm; the inner diameter forming the cirque is between Phi 1.6 and 3.6mm, and the outer diameter is in the range of Phi 2 and 4mm; a normal conical lead hole is employed. The fiber section shape is changed through the heavy denier round hollow fiber spinneret plate, thus leading the section of the spun fiber to be of a round hollow shape; meanwhile, the size of the fiber is above 6.67 dtex; as an empty hole is arranged in the fiber, the fiber has the advantages of light weight, fluffy and good spreadability. Meanwhile, the inside of the fiber does not generate convective air, thus generating the function of an isolation chamber. The fiber product is suitable for decorative materials and carpets, and can play the role of sound insulation and heat preservation.

Description

A kind of spinnerets of thick dawn circle doughnut

Technical field

The spinnerets of thick dawn circle doughnut of the present utility model relates to the synthetic fiber production field in the textile industry, particularly the production equipment field of polyester staple fiber.

Background technology

Terylene has just begun the paces of imitated natural fabric since invention, by the analysis to the fibre section, people have developed various profiled filaments, and the circle doughnut is wherein a kind of.By adopting the spinnerets of thick dawn circle doughnut, change the fibre section shape, make the fibre section that is spun into be round hollow type, the fiber number of fiber is more than 6.67dtex simultaneously, this fiber is owing to have the cavity in the middle of the fiber, so fiber has light weight, fluffy, advantage that spreadability is good.The doughnut of Sheng Chaning is the porous coarse denier fiber in the market, and thick dawn doughnut is exactly to have a plurality of cavitys in the middle of a crude fibre, is generally four holes, seven apertures in the human head, nine holes etc., because fiber is thick, the flexibility of fiber is poor, only is suitable for doing bedding, as hollow warm-keeping quilt, pillow.

Summary of the invention

The purpose of this utility model provides a kind of spinnerets of thick dawn circle doughnut, produces the fiber product that its cross section is round hollow type through supporting spinning and draft process; Make and be rich in the air that does not produce convection current in the fiber, thus the function of generation isolation ward, and this fiber product is applied to ornament materials, carpet, can play the effect of sound insulation, insulation.

For achieving the above object, the utility model has designed following technical scheme: (1) circle hollow type single hole is of a size of: be designed to a kind of annular by traditional circle hole shape, on annulus 2, have breach 3, breach is one, breach size on the annulus is 0.2～0.4mm, the interior diameter of forming annulus is φ 1.6～3.6mm, and overall diameter is in φ 2～4mm scope, adopts conventional taper guide hole; (2) arranged distribution of justifying the hollow hole shape is: on spinnerets, be the multilayer concentric circle and distribute, and each circle hollow type silk hole, its breach is docile and obedient the tangential direction that clockwise points to circumference, and the adjacent holes spacing equates; (3) spinneret orifice on the spinnerets is 120～150 holes.

The beneficial effects of the utility model are, owing to adopted the spinnerets of thick dawn circle doughnut, change the fibre section shape, make the fibre section that is spun into be round hollow type, the fiber number of fiber is more than 6.67dtex simultaneously, this fiber is owing to there is the cavity in the middle of the fiber, so fiber has light weight, fluffy, advantage that spreadability is good, make simultaneously and be rich in the air that does not produce convection current in the fiber, thereby produce the function of isolation ward, this fiber product is applicable to ornament materials, carpet, can play the effect of sound insulation, insulation.

The specific embodiment

Embodiment 1:

When producing the 6.67dtex staple fibre, the concrete size of its spinneret orifice is as follows:

Breach size on the annulus is 0.2mm, and the interior diameter of forming annulus is φ 1.6mm, and overall diameter is φ 2mm.

The geometric position in silk hole is: the silk geometric position of hole on spinnerets of described round hollow type cross-section fibers is each circle hollow type silk hole, and its breach is docile and obedient the tangential direction that clockwise points to circumference.

Silk hole count on the spinnerets is 150 holes.

The process technology of spinnerets is common prior art.

Embodiment 2:

When producing the 11.11dtex staple fibre, the concrete size of its spinneret orifice is as follows:

Breach size on the annulus is 0.35mm, and the interior diameter of forming annulus is φ 2.6mm, and overall diameter is φ 3mm.

Silk hole count on the spinnerets is 120 holes.

The process technology of spinnerets is common prior art.

Embodiment 3:

When producing the 13.33dtex staple fibre, the concrete size of its spinneret orifice is as follows:

Breach size on the annulus is 0.3mm, and the interior diameter of forming annulus is φ 3.6mm, and overall diameter is φ 4mm.

Silk hole count on the spinnerets is 120 holes.

The process technology of spinnerets is common prior art.

The spinnerets of a kind of thick dawn circle doughnut of the present utility model is not limited to above fact Example.
