Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, and more particularly to breathable and comfortable polyester fabrics. Background Art

[0002] Polyester fiber, commonly known as polyester, is a common synthetic fiber. Polyester fiber not only has good wrinkle resistance and shape retention, but also has certain strength and elastic recovery properties. Therefore, polyester fiber is a common material used to make clothing.

[0003] In order to ensure the breathability and comfort of clothing fabrics during use, a large number of holes are often opened inside the fabrics. External light will pass through the holes and illuminate the user's body surface. In order to reduce the light transmittance of the fabric, the weaving density of the fabric is increased to reduce the channels for light to pass through the fabric. This will make the user feel stuffy. Therefore, a structure is set up to solve the problem that the fabric cannot take into account both breathability and sun protection. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a breathable and comfortable polyester fabric, which can improve the overall breathable and comfortable performance of the fabric through structural settings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] This breathable and comfortable polyester fabric, as Figure 1 and Figure 2 shown, includes a base layer 1. The single-layer arrangement of the fabric speeds up the air circulation and exchange on both sides of the fabric, ensuring the overall breathable comfort of the fabric. A plurality of through grooves 2 are formed in the thickness direction of the base layer 1 by a laser drilling machine. The setting of the through grooves 2 provides a stable channel for outside air to enter the fabric interior, enabling the fabric interior to have outside flowing air for a long time, and further enhancing the breathability during the use of the structure.

[0020] As Figure 1 andFigure 2 As shown, a shielding piece 3 is sewn on the base layer 1 by a sewing machine. The width of the shielding piece 3 is greater than the width of the through groove 2, thus ensuring the stable shielding of the through groove 2 by the shielding piece 3 and reducing the external light directly irradiating on the user's body surface through the through groove 2. On the other hand, the setting of the shielding piece 3 reduces the contact area between the base layer 1 and the user's body surface, enabling the external air to better carry away the sweat on the shielding piece 3 and the user's body surface. Through the structural setting, the structure can take into account a certain breathability while ensuring the sun protection performance.

[0021] As Figure 1 and Figure 2 shown, the surface roughness of the shielding piece 3 is greater than that of the base layer 1. By increasing the surface roughness of the shielding piece 3, the light irradiating on the shielding piece 3 can be better diffused and reflected, further reducing the amount of light passing through the shielding piece 3. On the side of the base layer 1 away from the shielding piece 3, a breathable piece 4 is sewn by a sewing machine. The setting of the breathable piece 4 increases the thickness of the fabric, enabling the external light to be better absorbed and reflected inside the fabric. A breathable cavity is formed between the breathable piece 4 and the base layer 1, and the setting of the breathable cavity increases the amount of external air flowing inside the fabric, enhancing the breathability of the fabric.

[0022] As Figure 1 and Figure 2 shown, several reinforcing pieces 5 are integrally formed on both sides of the shielding piece 3. The light absorption property of the reinforcing pieces 5 is greater than that of the base layer 1. By setting the reinforcing pieces 5, the surface roughness of the shielding piece 3 is increased. The setting of the reinforcing pieces 5 can support the shielding piece 3 and the base layer 1, enabling a channel for the external air to flow between the shielding piece 3 and the base layer 1. On the other hand, the setting of the reinforcing pieces 5 further reduces the contact area between the shielding piece 3 and the user's body surface, increasing the channel for the external air to flow between the base layer 1 and the user's body surface, ensuring the breathable and sun protection performance of the fabric.

[0023] As Figure 1 and Figure 2 shown, on the side of the breathable piece 4 close to the base layer 1, breathable grooves 6 are formed by hot pressing with a hot press. The breathable cavity is formed by enclosing through the breathable grooves 6 and the base layer 1. The setting of the breathable grooves 6 reduces the thickness of the breathable piece 4, thereby accelerating the flow rate of the air on both sides of the fabric and enhancing the breathable comfort of the fabric.

[0024] As Figure 2 shown, several light-absorbing fluffs 7 are fixedly connected to the inner wall of the breathable grooves 6. The light-absorbing fluffs 7 include several bamboo charcoal fibers I. The bamboo charcoal fibers I are fixed on the inner wall of the breathable grooves 6 by the electrostatic flocking method of a flocking machine. The bamboo charcoal fibers I are often in a darker gray color. Therefore, the light-absorbing fluffs 7 can further absorb the light entering the breathable cavity under the action of the bamboo charcoal fibers I, reducing the divergence amount of the external light in the breathable cavity.

[0025] As Figures 1-3 shown, the shielding sheet 3 is woven by shielding yarns 8. The shielding yarns 8 include a first shielding yarn core 9 and a second shielding yarn core 10. The first shielding yarn core 9 and the second shielding yarn core 10 are twisted by a twisting machine to form the shielding yarns 8. The diameter of the first shielding yarn core 9 is larger than that of the second shielding yarn core 10. By increasing the diameter of the first shielding yarn core 9, a reinforcing member 5 can be naturally formed on the surface of the shielding sheet 3 during weaving, ensuring the stability of the structure during production and use.

[0026] As Figures 1-4 shown, the first shielding yarn core 9 is twisted by bamboo charcoal fiber two by a twisting machine. Bamboo charcoal fiber two not only has good light absorption, but also has good air permeability, enabling external air to better pass through the shielding sheet 3 and contact the user's body surface, ensuring the overall sun protection and air permeability of the structure. The second shielding yarn core 10 is twisted by polyester fiber by a twisting machine. The polyester fiber has good abrasion resistance and shape retention. The durability of the overall structure is enhanced by the setting of the polyester fiber.

[0027] As Figure 2 and Figure 4 shown, the breathable sheet 4 is woven by breathable yarns 11. The breathable yarns 11 include a first breathable yarn core 12 and a second breathable yarn core 13. The first breathable yarn core 12 and the second breathable yarn core 13 are twisted by a twisting machine to form the breathable yarns 11. The first breathable yarn core 12 is twisted by polyester profiled fiber with a cross-sectional shape by a twisting machine. The setting of the polyester profiled fiber increases the channels for external air to flow through inside the breathable yarns 11 and the breathable sheet 4, further enhancing the breathable comfort of the overall structure. The second breathable yarn core 13 is twisted by acrylic fiber by a twisting machine. The acrylic fiber has good sunlight resistance, and the structural strength will not decrease even when the acrylic fiber is exposed to light for a long time. The characteristics of the acrylic fiber are used to ensure the light resistance and durability of the fabric.

[0028] As Figures 1-4 shown, the base layer 1 is formed by weaving polyester yarns in a loom. A number of through slots 2 are cut along the thickness direction of the base layer 1 by a laser cutting machine. The breathable yarns 11 are put into a loom to weave a breathable layer. A number of breathable slots 6 are hot-pressed along one side of the breathable layer by a hot press. A light-absorbing fleece 7 is flocked on the inner wall of the breathable slots 6 by a flocking machine. The shielding yarns 8 are put into a loom to weave a shielding layer and a reinforcing member 5. The breathable layer and the shielding layer are respectively cut by a laser cutting machine to form a number of breathable sheets 4 and shielding sheets 3. Finally, the breathable sheets 4 and the shielding sheets 3 are sewn on both sides of the base layer 1 by a sewing machine.

[0029] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
