Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a breathable polyester filament. Background Art

[0002] Fibers are not only the basic components of textiles, but also determine the functionality of the final product. Breathability is an important characteristic of fibers. Fibers with good breathability can allow air to circulate between fibers, thereby regulating gas exchange and humidity balance inside the fabric, providing a comfortable feeling for the wearer. The quality of breathability directly affects the wearing experience of textiles, especially in hot or humid environments. Fibers with good breathability can effectively reduce the feeling of stuffiness and sweat, and improve the comfort of the wearer.

[0003] The realization of breathability usually depends on the unique structure and processing technology of the fiber. For example, natural fibers such as cotton, linen and silk usually have good breathability due to their natural porous structure and low density. There are many tiny gaps in the microstructure of these fibers, allowing air to pass freely.

[0004] However, for chemical fibers, which are obtained by hot-melt spinning or wet spinning, their structure itself is relatively strict, and there are no tiny pores for air to pass through and circulate, thus ensuring their breathability.

[0005] Therefore, a breathable polyester filament is proposed to solve or alleviate the above problems. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and provides a breathable polyester filament.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A breathable polyester filament comprises an inner ring portion, an outer ring portion coaxially arranged on the outer ring portion, and a plurality of connecting portions connecting the two, wherein the inner ring portion has an inner ring forming a hollow portion, and an outer hollow portion is formed between adjacent connecting portions, and the outer ring portion is provided with a plurality of through holes 1 connected to the outer hollow portion, the connecting portion is provided with a through hole 2 connected to adjacent outer hollow portions, and the inner ring portion is provided with a through hole 3 connecting the outer hollow portion and the inner hollow portion.

[0009] Preferably, the inner ring of the outer ring portion is flush, and the outer ring thereof is arranged in a concave-convex manner, and the concave portion and the convex portion of the outer ring portion are arranged alternately in sequence, and the through hole is opened in the concave portion of the outer ring portion.

[0010] Preferably, the thickness of the connecting portion, the thickness of the recessed portion of the outer ring portion, and the thickness of the inner ring portion are the same.

[0011] Preferably, the inner ring portion is composed of a plurality of inner polyester filaments, and the connecting portion is composed of a plurality of connecting polyester filaments.

[0012] Preferably, the outer ring portion is composed of an equal number of external connecting polyester threads and external receiving polyester threads, and the cross-sectional area of ​​the external connecting polyester threads is greater than the cross-sectional area of ​​the external receiving polyester threads.

[0013] Preferably, the inner ring portion, the outer ring portion, and the connecting portion are all integrally formed structures.

[0014] The utility model has the following beneficial effects:

[0015] The utility model combines an integrally formed structure, and through the three key components of an inner ring portion, a connecting portion and an outer ring portion, a polyester filament with a complete structure is formed. The polyester filament has a plurality of recesses on its surface, and a through hole 1 is provided in these recesses, while a through hole 2 and a through hole 3 are respectively located on the connecting portion and the inner ring portion. The provision of these through holes increases the air permeability of the polyester filament, connects it with the external environment, and allows air to flow freely.

[0016] This improvement in air permeability is a proper improvement for traditional chemical fiber materials such as polyester. Polyester filaments can maintain their original strength and durability while introducing good air exchange capabilities through these through holes. These through holes play a key role in the process of polyester filaments forming a fluffy structure. They not only help the air flow inside the fiber, but also guide the air to circulate along the fiber surface, thereby effectively improving the air permeability of the fiber.

[0017] In addition, this design also takes into account the actual application needs of the fiber, especially in textiles that require good breathability. Through this structure of polyester filaments, textiles can maintain their original appearance and feel while having better wearing comfort and breathability.

[0018] In summary, the polyester filament of the utility model, through its unique structural design and through-hole layout, improves its breathability while maintaining the inherent advantages of polyester material, so that this chemical fiber material can better meet the requirements of modern textiles for breathability.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] A breathable polyester filament, such as Figure 1 and 2 As shown, it includes an inner ring portion, an outer ring portion coaxially arranged on its outer ring, and a plurality of connecting portions connecting the two. The inner ring portion, the outer ring portion, and the connecting portions are all integrally formed structures.

[0025] The inner ring part is composed of a plurality of inner polyester yarns 1, the inner circle of the inner ring part forms a hollow part 5, and a through hole three connecting the outer hollow part 6 and the inner hollow part is opened on the inner ring part.

[0026] The connecting part is composed of a plurality of connected polyester yarns 2, an outer space 6 is formed between adjacent connecting parts, and a through hole 2 for connecting adjacent outer space 6 is opened on the connecting part.

[0027] The inner circle of the outer ring part is flush, and its outer circle is concave and convex, and the concave part and the convex part of the outer circle of the outer ring part are arranged alternately in sequence. The outer ring part is composed of the same number of external connecting polyester yarns 3 and external supporting polyester yarns 4. The cross-sectional area of ​​the external connecting polyester yarns 3 is larger than the cross-sectional area of ​​the external supporting polyester yarns 4, and a plurality of through holes 1 connected to the outer space 6 are opened on the outer ring part, and the through holes 1 are opened in the concave part of the outer ring part.

[0028] The thickness of the connecting portion, the thickness of the recessed portion of the outer ring portion, and the thickness of the inner ring portion are the same.

[0029] The utility model forms a complete polyester filament through an integrally formed inner ring portion, a connecting portion, and an outer ring portion, and the polyester filament can be connected to the outside, the hollow portion 5, and the outer hollow portion 6 through a through hole 1 in the concave portion on its surface, a through hole 2 on the connecting portion, and a through hole 3 on the inner ring portion, so that the polyester filament can have good air permeability. When the polyester filament forms a fluffy structure, it can also guide air to circulate through the polyester filament, thereby ensuring that it has acceptable air permeability, so that the chemical fiber made of polyester material can also have sufficient pores for ventilation.

[0030] When you need to get this polyester filament, Figure 3As shown, only the special-shaped spinneret 7 is needed to perform the spinning. There are 11 inner holes 8 on the spinneret 7 for ejecting the inner polyester yarn 1. At the same time, there are 6 groups of connecting holes 9 distributed in the outer circles of the inner holes 8 in an annular array. The number of each group of connecting holes 9 is 2.
