Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and more specifically, to a polyester fabric. Background Technology

[0002] Polyester fabric is a type of synthetic fiber clothing material that is frequently used in daily life. Its biggest advantages are its excellent wrinkle resistance and shape retention, making it suitable for making outerwear, various bags, tents, and other outdoor products.

[0003] Breathability is an essential characteristic of clothing fabrics. Reducing the weave density of the fabric or creating several pores are common ways to ensure breathability. However, when people are outdoors in summer, external light can easily pass through these pores and come into contact with the skin. Therefore, a solution is needed to address the problem that some fabrics cannot simultaneously achieve both breathability and light blocking. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyester fabric.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester fabric includes a base layer, with a shielding piece and a contact piece fixedly connected to both sides of the base layer, the width of the contact piece being smaller than the width of the shielding piece, and a plurality of support blocks one and two that abut against the base layer being fixedly connected to the shielding piece and the contact piece, respectively, the contact piece having a plurality of through holes, the base layer having a plurality of through holes, and a breathable space one being formed between the contact piece and the base layer, the through holes, the through holes and the breathable space one being interconnected.

[0006] The present invention is further configured such that the distance between adjacent contact pieces is greater than the distance between adjacent shielding pieces, and there are ventilation channels between adjacent support blocks one and adjacent support blocks two.

[0007] The present invention is further configured such that the through hole and the through hole are misaligned, and the diameter of the through hole is larger than the diameter of the through hole.

[0008] The present invention is further configured such that: the shielding piece and the first support block, and the contact piece and the second support block are all integrally formed, and the shielding piece and the contact piece are both configured with a textured pattern.

[0009] The present invention is further configured such that the base layer, the contact sheet and the shielding sheet are all woven from composite yarn, and the composite yarn includes a yarn core and a covering yarn spirally wound on the outer peripheral wall of the yarn core.

[0010] The present invention is further configured such that: the yarn core is made of twisted polyester fibers, and the covering yarn is made of twisted polyester shaped fibers with a cross-shaped cross section.

[0011] In summary, this utility model has the following beneficial effects: the setting of the shielding sheet, the base layer and the contact sheet increases the overall thickness of the fabric, so that light is gradually absorbed and reflected inside the fabric, reducing the amount of light passing through the fabric and shining on the body surface. The smaller width of the contact sheet and the larger distance between adjacent contact sheets ensure that the contact sheet can block the through hole while increasing the air flow between the fabric and the body surface, so that the fabric can simultaneously achieve both light blocking and breathability.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] This type of polyester fabric, such as Figure 1 and Figure 2 As shown, the fabric includes a base layer 1, with a shielding piece 2 and a contact piece 3 sewn onto both sides of the base layer 1. Support blocks 1 4 and 2 5, which abut against the base layer 1, are integrally formed on the shielding piece 2 and contact piece 3, respectively. The shielding piece 2 and contact piece 3 increase the overall thickness of the fabric, allowing more light to be absorbed and reflected within the fabric, thus reducing the amount of light passing through the fabric and contacting the body surface, ensuring the overall light-blocking effect of the fabric. Both the shielding piece 2 and contact piece 3 are constructed with a patterned weave. The ground weave of the patterned weave consists of the shielding piece 2 and contact piece 3, while the patterned weave consists of several support blocks 1 4 and support blocks 2 5, ensuring the stability of the fabric during production and use.

[0018] like Figure 1 and Figure 2As shown, a first air-permeable space is formed between the contact piece 3 and the base layer 1, and a second air-permeable space is formed between the shielding piece 2 and the base layer 1. Both adjacent support blocks 4 and 5 have air-permeable channels. This structural arrangement increases the channels through which air flows within the fabric. The width of the contact piece 3 is smaller than the width of the shielding piece 2, reducing the distance between the base layer 1 and the body surface. The distance between adjacent contact pieces 3 is greater than the distance between adjacent shielding pieces 2, thereby increasing the amount of air flowing between the base layer 1 and the body surface, ensuring the overall breathability and comfort of the fabric. Several through holes 7 are provided on the base layer 1, and several through holes 6 are provided on the contact piece 3, offset from the through holes 7. During use, outside air will enter through the air-permeable channels. The light enters the second breathable space, then enters the first breathable space through the through hole 7, and finally passes through the through hole 6 to contact the body surface. The blocking plate 2 is located above the through hole 7, so external light shines on the blocking plate 2 instead of directly passing through the through hole 7. At the same time, due to the staggered setting of the through hole 7 and the through hole 6, when some light passes through the through hole 7, it will shine on the contact plate 3 instead of directly passing through the through hole 6 to contact the body surface. This allows the fabric to simultaneously achieve both light blocking and breathability. During the cutting and forming process, making the diameter of the through hole 6 larger than the diameter of the through hole 7 can reduce the amount of light entering the fabric through the through hole 7, and reduce the contact area between the contact plate 3 and the body surface while increasing the amount of air in contact with the body surface, thus enhancing the fabric's performance.

[0019] like Figures 1-3 As shown, the base layer 1, contact sheet 3, and shielding sheet 2 are all woven from composite yarn 8. The composite yarn 8 includes a yarn core 9 and a covering yarn 10 spirally wound on the outer periphery of the yarn core 9. The yarn core 9 and the covering yarn 10 are processed by a spinning process to form the composite yarn 8. The yarn core 9 is made of polyester fiber twisted by a twisting machine, and the covering yarn 10 is made of polyester profiled fiber with a cross-shaped cross section twisted. Polyester fiber not only has high structural strength but also good light resistance. The setting of polyester profiled fiber increases the channels for external air to flow through the inside of the yarn, ensuring the overall light-blocking and breathable effect of the structure.

[0020] like Figures 1-3As shown, when this fabric needs to be made, the composite yarn 8 is placed in a loom and woven to form a base layer 1. Several through holes 7 are made along the thickness direction of the base layer 1 using a laser perforation machine. The composite yarn 8 is placed in the loom and woven with a patterned weave to form a contact layer and several support blocks 2 5. Several through holes 6 are made along the thickness direction of the contact layer using a laser perforation machine. The contact layer is then cut with a laser cutting machine to form several contact pieces 3 with several support blocks 2 5. The composite yarn 8 is placed in the loom and woven with a patterned weave to form a shielding layer and several support blocks 1 4. The shielding layer is then cut with a laser cutting machine to form several shielding pieces 2 with several support blocks 1 4. Finally, the shielding pieces 2 and contact pieces 3 are sewn to both sides of the base layer 1 using a sewing machine. The fixing points of the shielding pieces 2 and contact pieces 3 are both set at both ends of their own length direction.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
