Abstract
The utility model discloses a spinneret realizing staggering of two components. The spinneret comprises a spinneret core, a spinneret plate, a left pipeline and a right pipeline, wherein the spinneret core is communicated with the left pipeline and the right pipeline respectively. The spinneret is characterized in that the spinneret holes in the left half area of the spinneret plate are communicated with the left pipeline; the spinneret holes in the right half area of the spinneret plate are communicated with the right pipeline; the spinneret holes in the left half area are inclined right and down and run through the spinneret plate; the spinneret holes in the right half area are inclined left and down and run through the spinneret plate. According to the spinneret, the left and right pipelines are arranged in the spinneret, so that the two components of different materials can be extruded out from the spinneret plate through respective melt channels; the spinneret holes are formed in the directions which form a certain angle with the vertical direction, so that the newborn fibers, formed by the two materials, are staggered but not intersect with each other after being extruded out to form a bunch of fibers, and thus are mixed uniformly to form the bunch of fibers while not sticking to each other.
Description
Technical field
The utility model belongs to synthetic fiber spinning field, relates in particular to the staggered spinning head of a kind of two component.
Background technology
Spinning head is the integral part for producing continuously the melt spinning device of composite yarn.Spinning head makes that polymer melt is squeezed into many wire long filaments becomes possibility, and long filament some strands is combined to form composite yarn.Therefore such spinning head conventionally has the spinnerets that comprises multiple spinneret orifices on their bottom side, and polymer melt is extruded by this nozzle plate to squeeze out long filament.The material of two kinds of different performances mixed in spinning head or do not mix, obtaining the special fibrous material of performance from spinnerets ejection.The composite fibres such as current sea island filament have been two components or even multi-component material, but how the fibrous material of two components is fully arranged in pairs or groups evenly after spray silk forms tow, particularly just carrying out the mixing of two kinds of spun filament but do not produce adhesion in fibroblast process is current a difficult problem.
Summary of the invention
In order to overcome this problem, the utility model provides a kind of two component staggered spinning head, does not produce adhesion for the polymer melt of two kinds of different materials is fully mixed spun filament but mixed in the time just extruding.
The technical solution of the utility model is to provide the staggered spinning head of a kind of two component, comprise spinning head core body, spinnerets, left pipeline and right pipeline, described spinning head core body respectively with described left pipeline and described right pipeline communication, it is characterized in that, in half region, described spinnerets left side, spinneret orifice is communicated with described left pipeline, in half region, right side, spinneret orifice is communicated with described right pipeline, described left side spinneret orifice tilts to run through described spinnerets to lower right, and described right side spinneret orifice to left down square neck tiltedly runs through described spinnerets.
As preferred version, the spinneret orifice extension line in half region, described spinnerets left side and the spinneret orifice extension line in half region, the described spinnerets right side woven areas that is staggered is positioned at described spinnerets front.
As preferred version, the extension line of all described spinneret orifices is staggered and interweaves but non-intersect.
As preferred version, between described spinneret orifice axis and vertical curve, angle is 15 °-45 °.
As preferred version, in described spinnerets, be also provided with distribution plate and filter screen, what described left pipeline and described right pipeline below walked abreast respectively is provided with the described distribution plate of two covers and described filter screen, and described filter screen connects respectively the left and right two halves of described spinnerets.
The of the present utility model pair of staggered spinning head of component, two pipelines in left and right are set in spinning head inside, two kinds of different material components are extruded from spinnerets by melt canal separately, spinneret orifice setting and vertical direction have the direction of certain angle, the spun filament of bi-material is interweaved but a branch of tow of disjoint composition after ejection, and spun filament mixes bunchy can not adhesion in the situation that like this.

Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the staggered spinning head of the two components of one of the present utility model, comprise spinning head core body 1, spinnerets 2, left pipeline 3 and right pipeline 4, spinning head core body 1 is communicated with left pipeline 3 and right pipeline 4 respectively, in spinnerets 2 half regions, left side, spinneret orifice 7 is communicated with left pipeline 3, in half region, right side, spinneret orifice 7 is communicated with right pipeline 4, in spinnerets 2, be also provided with distribution plate 5 and filter screen 6, what left pipeline 3 and right pipeline 4 belows walked abreast respectively is provided with two cover distribution plates 5 and filter screen 6, and filter screen 6 connects respectively the left and right two halves of spinnerets 2.
Spinneret orifice 7 extension lines in spinneret orifice 7 extension lines in spinnerets 2 half regions, left side and spinnerets 2 half regions, the right side woven areas that is staggered is positioned at spinnerets 2 fronts, but non-intersect, left side spinneret orifice 7 tilts to run through spinnerets 2 to lower right, right side spinneret orifice 7 to left down square neck tiltedly runs through spinnerets 2, and between spinneret orifice 7 axis and vertical curve, angle is 30 °.
When the utility model work, the melt high polymer of two kinds of different materials compositions enters after distribution plate 5 and filter screen 6 by left pipeline 3 and right pipeline 4 respectively, enter corresponding spinnerets 2 half regions, left side and half region, right side, and extrude from spinneret orifice 7, between spinneret orifice 7 axis of left side half and vertical curve, angle is 30 ° and tilts towards right side; Equally, between spinneret orifice 7 axis of right side half and vertical curve, angle is 30 ° and towards left side.Due to the setting that is staggered of the spinneret orifice 7 of the left and right sides, the spun filament in all spinneret orifices 7 is interweaved but non-intersect at spinnerets 2 front areas, after cooling processing, and a branch of two component tow that mix of fully crossing silk thread composition.
The feature that spinnerets 2 of the present utility model designs due to spinneret orifice 7 makes silk thread can not produce contact in the process of being interweaved to stick together, can fully mix in the spun filament stage again simultaneously, make a branch of silk thread fully demonstrate the advantage of bi-material characteristic.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
