Abstract

The invention relates to a spinneret plate for spinning. The spinneret plate comprises a spinneret plate body, wherein spinneret orifices are uniformly distributed on the spinneret plate body densely; the cross section of each spinneret orifice comprises a round hole at the center and three strip holes extending outward by taking the round hole as the center; and the three strip holes are uniformly distributed annularly. The spinneret plate provided by the invention is suitable for spinning.

Description

A kind of spinnerets for spinning

Technical field

The present invention relates to a kind of spinnerets for spinning.

Background technology

In spinning process, the melt of molten condition is conveyed into spinning manifold through transfer passage, form tow behind the spinnerets in spinning manifold, then through the cooling air cooling, final by the coiling groove coiling and molding on the groove moving axis.The structure of present employed spinnerets comprises a spinnerets body, evenly is densely covered with spinneret orifice on the spinnerets body, and usually spinneret orifice is shaped as circle.But the smooth surface of the prepared fiber of spinnerets that is shaped as pure circle of spinneret orifice easily form diffuse reflection when light shines the surface, so its prepared fabric sheen is relatively poor, is difficult to satisfy people's demand; In addition, the hygroscopicity of its prepared fabric is relatively poor, chromatophilia is also relatively poor.

Summary of the invention

Technical problem to be solved by this invention is: a kind of spinnerets for spinning is provided, and the fabric sheen of its prepared fiber is better, and hygroscopicity is strong, chromatophilia is better.

For addressing the above problem, the technical solution used in the present invention is: a kind of spinnerets for spinning, comprise a spinnerets body, evenly be densely covered with spinneret orifice on the spinnerets body, the cross section of described spinneret orifice comprise the circular hole that is positioned at the center and centered by circular hole outward extending three strip holes, three strip holes evenly distribute along annular.

The invention has the beneficial effects as follows: the above-mentioned spinnerets that is used for spinning, the special shape of its spinneret orifice, so the cross-section center of its prepared fiber is circular, and there are three strip shape bifurcateds the outside, with the prepared Fiber Phase ratio of circular spinneret orifice, its surface is difficult for forming diffuse reflection, so its prepared fabric sheen is better, and hygroscopicity is strong, chromatophilia is better.

Description of drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is the cross sectional representation of spinneret orifice among Fig. 1;

Among the figure: 1, spinnerets body, 2, spinneret orifice, 3, circular hole, 4, strip hole.

The specific embodiment

Below by specific embodiment a kind of spinnerets for spinning of the present invention is described in further detail.

As shown in Figure 1, a kind of spinnerets for spinning, comprise aspinnerets body 1, evenly be densely covered withspinneret orifice 2 on thespinnerets body 1, as shown in Figure 2, the cross section of describedspinneret orifice 2 comprisescircular hole 3 and 4, three strip holes of outward extending three strip holes, the 4 evenly distributions of edge annular centered bycircular hole 3 that are positioned at the center.

The invention has the beneficial effects as follows: the above-mentioned spinnerets that is used for spinning, the special shape of its spinneret orifice, so the cross-section center of its prepared fiber is circular, and there are three strip shape bifurcateds the outside, with the prepared Fiber Phase ratio of circular spinneret orifice, its surface is difficult for forming diffuse reflection, so its prepared fabric sheen is better, and hygroscopicity is strong, chromatophilia is better.

Claims (1)

1. spinnerets that is used for spinning, comprise a spinnerets body, evenly be densely covered with spinneret orifice on the spinnerets body, it is characterized in that: the cross section of described spinneret orifice comprise the circular hole that is positioned at the center and centered by circular hole outward extending three strip holes, three strip holes evenly distribute along annular.
