Composite spining module

A composite spinning and assembly technology, which is applied in the direction of feeding solution to the spinneret, etc., can solve the problems that the fiber cannot produce ultra-fine fibers, the quality of the fabric is poor, and the energy consumption increases, so as to reduce equipment and manpower investment and improve health. Bone and stiffness, the effect of shortening the process

Problems solved by technology

Its disadvantage is that the component cannot produce ultra-fine denier blended filaments, and the fineness of the thinnest single filament is usually above 0.55dtex. Although the fleece effect is achieved in the post-processing, the hand feeling of the fabric produced is compared with that of ultra-fine fibers. worse
[0005] Therefore, among the existing three kinds of spinning components, the fibers produced by the single component components cannot produce ultrafine fibers; The softness of filaments and fabrics cannot meet the requirements of downstream users; while the ultrafine fibers produced by composite spinning components can reach very fine single filament fineness, but the fabric body is very poor and cannot be directly used for weaving. It must be combined with thicker monofilament fibers to make mixed fiber yarns to meet the requirements of subsequent users. This virtually increases the process and equipment, increases investment, and increases energy consumption.

Embodiment 1

[0032] There are 72 grooves such as: figure 2 and image 3 As shown in the bosses, there are two melt channels inside each boss, and 72 bosses are distributed in a ring, of which 18 bosses are located in the inner ring (center position) of the composite plate, and the other 54 bosses are They are located in the outer two circles respectively. A closed metal ring is arranged on the outer rings of the 18 bosses at the center of the composite plate, so that only one kind of melt can flow through the 18 bosses. Then the composite plate and spinneret, distribution plate and other parts are packed into a complete composite spinning assembly, and the two polymer melts of PET (polyester) and PA-6 (polyamide 6) are as follows Process conditions for spinning: PET melt can flow through all bosses, while PA-6 melt can only flow through 54 bosses that are not isolated, PET melt temperature (main box temperature) 286 ~ 296 ° C , PA-6 melt temperature 258 ~ 275 ℃, PET melt extrusion volu...

Embodiment 2

[0035] There are 72 grooves such as: figure 2 and image 3 As shown in the bosses, there are two melt channels inside each boss, and 72 bosses are distributed in a ring, of which 18 bosses are located in the inner ring (center position) of the composite plate, and the other 54 bosses are They are located in the outer two circles respectively. Randomly select 18 bosses from the 72 bosses, and add a metal ring around them. These metal rings isolate these 18 bosses from the other 54 bosses. The interior of these 18 bosses is Only one kind of melt is allowed to flow through, and the spinneret hole above the spinneret below it is designed as a special-shaped hole. Then the composite plate and spinneret, distribution plate and other parts are packed into a complete composite spinning assembly, and the two polymer melts of PET (polyester) and PA-6 (polyamide 6) are as follows Process conditions for spinning: PET melt can flow through all bosses, while PA-6 melt can only flow thro...

Abstract

The present invention relates to one composite spinning module for producing superfine blended fiber. The composite spinning module has inside its casing an upper cover plate, a filtering net, an upper distribution plate, a lower distribution plate, a compounding plate and a spinning plate, and features that some of the bosses below the compounding plate have inside passage for two different kinds of melt to pass through while the others have inside passage for only one kind of melt to pass through. Using the composite spinning module can produce superfine blended fiber in one-step process, and the superfine blended fiber may be used in making product with high stiffness and soft hand feeling, including superfine suede fabric, cleaning cloth, quick dry towel, etc. The technology of the present invention may be also applied in other composite spinning modules.

Description

technical field [0001] The invention relates to a spinning assembly, in particular to a composite spinning assembly, in particular to a composite spinning assembly for producing superfine fiber mixed filaments, and belongs to the technical field of synthetic fiber production. Background technique [0002] At present, there are three types of spinning components for the production of fine denier filaments. One is to produce single-component spinning components (the shape of the spinneret hole is round or shaped), and the fibers spun by this component contain only one polymer and the monofilament fineness is large, generally greater than 0.55dtex, the fiber cannot be used in fabrics such as ultra-fine suede fabrics, cleaning cloths, and quick-drying towels. [0003] The other is a composite spinning component used to manufacture composite fibers, which can produce stripped or island-in-the-sea composite fibers, which are stripped or dissolved by chemical or mechanical methods ...
