Description
Technical Field
The utility model relates to a spinneret specifically is a line and triangle-shaped blending acetate fiber spinneret.
Background
Cellulose acetate is an abbreviation of cellulose acetate, and refers to a thermoplastic resin obtained by esterification of acetic acid as a solvent and acetic anhydride as an acetylating agent under the action of a catalyst, and is a cellulose organic acid ester which is produced commercially at the earliest and is developed continuously in cellulose derivatives.
The spinneret plate of the conventional acetate fiber is in a round hole shape, so that the brightness and rigidity of the prepared tow are insufficient;
therefore, how to improve the brightness and rigidity of acetate fibers is a problem that researchers in the field need to solve urgently.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to improve the brightness and rigidity of acetate fiber;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a line and triangle-shaped blending acetate fibre spinneret, include: the spinneret plate is provided with an elongated slot, and the bottom of the elongated slot is provided with a plurality of micropores in a penetrating manner; the micropores comprise a plurality of triangular holes and straight holes; wherein, two triangular holes and one-to-one shaped hole are in one group, and a plurality of groups of holes are arranged at the bottom of the elongated slot in a circumferential and equal division manner; triangular holes are respectively arranged on two sides of the linear hole;
in the scheme, acetate fiber spinning is carried out by adopting two different hole shapes, namely a straight hole and a triangular hole, so that two different cross sections are obtained in a bundle of acetate fibers; the combination utilizes the characteristic that the fibers with the two cross sections of the straight-shaped hole and the triangular hole have better brightness, so that the fiber bundle has brighter appearance and can obtain high-grade feeling when being used for weaving clothes; the straight-line-shaped hole is adopted because the fiber with the cross section has the best brightness, and the fiber with the triangular cross section can be endowed with higher rigidity while maintaining higher brightness, thereby being beneficial to the shape maintenance of the clothes and enhancing the wrinkle resistance;
the two cross-section hole shapes are usually arranged on the spinneret plate in a staggered manner, so that the two fibers with different cross sections can be conveniently and fully mixed, and the prepared filament bundle can show the effect after mixing in all directions.
In order to concretely explain the arrangement structure of the triangular holes and the linear holes, the utility model adopts the shape of the triangular holes as equally divided triangles; the height direction of the two triangular holes in the same group is collinear with the length direction of the linear hole;
the triangular holes are formed in the two sides of each straight-shaped hole, so that the two fibers with different sections can be fully mixed.
The utility model has the advantages that: the utility model discloses a line and triangle-shaped blending acetate fibre spinneret can increase the luminance of tow through setting up the line hole, can increase the luminance and the rigidity of tow through setting up the triangle-shaped hole to reach acetate fibre shape-keeping, crease-resistant effect.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the utility model discloses a line and triangle-shaped blending acetate spinneret, include: the spinneret plate 1 is provided with a long groove, and the bottom of the long groove is provided with a plurality of micropores 2 in a penetrating way; the micropores comprise a plurality of triangular holes 3 and straight holes 4; wherein, two triangular holes 3 and one-to-one shaped holes 4 are in a group, and a plurality of groups of holes are equally arranged at the bottom of the long groove in a circumferential manner; triangular holes 3 are respectively arranged on two sides of the straight hole 4;
in the scheme, acetate fiber spinning is carried out by adopting two different hole shapes, namely a straight hole and a triangular hole, so that two different cross sections are obtained in a bundle of acetate fibers; the combination utilizes the characteristic that the fibers with the two cross sections of the straight-shaped hole and the triangular hole have better brightness, so that the fiber bundle has brighter appearance and can obtain high-grade feeling when being used for weaving clothes; the straight-line-shaped hole is adopted because the fiber with the cross section has the best brightness, and the fiber with the triangular cross section can be endowed with higher rigidity while maintaining higher brightness, thereby being beneficial to the shape maintenance of the clothes and enhancing the wrinkle resistance;
the two cross-section hole shapes are usually arranged on the spinneret plate in a staggered mode, so that two fibers with different cross sections can be conveniently and fully mixed, and the prepared filament bundles can have the effect after mixing in all directions.
As shown in fig. 2, in order to specifically describe the arrangement structure of the triangular holes and the linear holes, the triangular holes 3 of the present invention are equally divided into triangles; the height direction of the two triangular holes 3 in the same group is collinear with the length direction of the straight hole 4;
the triangular holes are formed in the two sides of each straight-shaped hole, so that the two fibers with different sections can be fully mixed.
As shown in FIGS. 3 and 4, the width W of the linear hole can be varied between 0.02 mm and 0.1mm according to different requirements of fineness, hand feeling, luster and the like of the spun fiber; in order to ensure that the obtained fiber has better profile tolerance, the ratio of the leaf length L to the leaf width W is more than or equal to 2.5 times (namely L/W is more than or equal to 2.5); the side length A of the triangular hole can be changed between 0.03 and 0.2 so as to prepare the acetate fiber with proper fineness.
The utility model discloses a line and triangle-shaped blending acetate fibre spinneret can increase the luminance of tow through setting up the line hole, can increase the luminance and the rigidity of tow through setting up the triangle-shaped hole to reach acetate fibre shape-keeping, crease-resistant effect.
