Description

Technical Field

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

[0002] Fabric is the material used to make clothing, while yarn is the material used to make fabric. Therefore, the characteristics of fabric are determined by the characteristics of the yarn that weaves it.

[0003] Polyester composite fabric is woven from polyester yarn and other chemical or natural yarns to give the fabric more properties at the same time. Breathability is a necessary feature of clothing fabrics, and adding pores to the fabric can enhance its breathability. However, during the use of clothing fabrics, external light can directly shine through the pores onto the skin.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide polyester composite fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the polyester composite fabric includes a base layer, on which a plurality of through grooves are arrayed, and a plurality of shielding pieces are sewn onto the base layer. The shielding pieces are provided with through grooves that are offset from the through grooves, and a support line is sewn onto the shielding pieces between the through grooves and the through grooves. The support line abuts against the base layer, and a plurality of light-absorbing fibers are provided on the side of the base layer near the shielding pieces between the through holes and the through grooves.

[0007] The present invention is further configured such that: the light-absorbing velvet is made of bamboo charcoal fiber, and the flocking density of the light-absorbing velvet on the base layer is 100-125 fibers per square centimeter.

[0008] The present invention is further configured such that: the support line forms a breathable channel between the base layer and the shielding sheet, and the through groove and the through groove are connected through the breathable channel.

[0009] The present invention is further configured such that: the cross-sectional area of ​​the through groove is smaller than the cross-sectional area of ​​the through slot, and the distance between adjacent through grooves arranged along the length direction of the shielding piece is greater than the distance between adjacent through slots.

[0010] The present invention is further configured such that: the base layer and the shielding sheet are both woven from composite yarn, the composite yarn including a yarn core and a covering yarn spirally wound on its outer peripheral wall.

[0011] The present invention is further configured such that: the yarn core is a polyester profiled yarn with a cross-shaped cross section, and the covering yarn is a bamboo charcoal yarn.

[0012] In summary, this utility model has the following beneficial effects: the setting of the shielding sheet increases the overall thickness of the fabric, allowing the light shining on the fabric to be better absorbed. Since the through slots and the through grooves are connected through the ventilation channel, while preventing external light from shining on the body surface through the through slots and the through grooves, it ensures stable communication of external air, allowing the fabric to simultaneously take into account sun protection and breathability.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] This polyester composite fabric, such as Figure 1 and Figure 2 As shown, the system includes a base layer 1. Several through-slots 2 are cut into the base layer 1 using a laser cutting machine array. The through-slots 2 reduce the contact area between the fabric and the body surface, while providing a channel for direct contact between outside air and the body surface. Several shielding sheets 3 are sewn onto the base layer 1 using a sewing machine. Several through-slots 4 are cut into one side of each shielding sheet 3. The side of the shielding sheet 3 without through-slots 4 is positioned corresponding to the through-slots 2 to seal them, preventing outside light from directly passing through the through-slots 2 and illuminating the body surface. The staggered through-slots 4 and through-slots 2 ensure that light entering the fabric along the through-slots 4 can illuminate the body surface. On the base layer 1, instead of passing directly through the through groove 2 and contacting the body surface, the setting of the shielding piece 3 also increases the overall thickness of the fabric, allowing more sunlight to be absorbed inside the fabric. By reducing the light shining on the body surface, the overall sun protection and light-blocking performance of the fabric is enhanced. The cross-sectional area of ​​the through groove 4 is smaller than that of the through groove 2, reducing the amount of light that can pass through the through groove 4 and enter the fabric. The distance between adjacent through grooves 4 along the length of the shielding piece 3 is greater than the distance between adjacent through grooves 2, which can increase the area of ​​the part of the shielding piece 3 without through holes and enhance the overall light-blocking effect of the fabric.

[0019] Figure 1 and Figure 2 As shown, a support line 5 is sewn onto the shielding piece 3 between the through groove 2 and the through groove 4 by a sewing machine. The side of the support line 5 closest to the base layer 1 abuts against the base layer 1. Therefore, a breathable channel is formed between the base layer 1 and the shielding piece 3 through the support of the support line 5. The through groove 2 and the through groove 4 are connected through the breathable channel. Therefore, outside air will enter the fabric through the through groove 4, circulate inside the breathable channel, and finally pass through the through hole to contact the body surface. This ensures the light blocking effect while enhancing the overall breathability and comfort of the fabric.

[0020] like Figure 1 and Figure 2 As shown, the base layer 1 near the shielding sheet 3 is flocked with several light-absorbing fibers 6 by a flocking machine. The light-absorbing fibers 6 are located between the through groove 2 and the through groove 4. Light entering the fabric through the through groove 4 will diffuse inside the fabric. The light-absorbing fibers 6 located between the through groove 2 and the through groove 4 can absorb this diffused light inside the fabric, further reducing the light that shines on the body surface through the through groove 2. The flocking density of the light-absorbing fibers 6 on the base layer 1 is 100-125 fibers per square centimeter. By reducing the number of fibers in the unit fabric, while ensuring the basic light-blocking effect of the structure, more outside air can flow more easily through the light-absorbing fibers 6 and through the through groove 2 to contact the body surface. Since the light-absorbing fibers 6 are made of bamboo charcoal fiber, the good light absorption and breathability of bamboo charcoal fiber can be used to ensure the overall light absorption and breathability of the fabric.

[0021] like Figure 1 and Figure 3 As shown, both the base layer 1 and the shielding sheet 3 are woven from composite yarn 7. The composite yarn 7 includes a yarn core 8 and a covering yarn 9 spirally wound on its outer periphery. The yarn core 8 and the covering yarn 9 are processed by a spinning process to form the composite yarn 7. The yarn core 8 is set as a polyester profiled yarn with a cross-shaped cross section. After the polyester yarn is profiled, it can increase the grooves inside the yarn for outside air to flow through while ensuring the yarn's light resistance and durability. The bamboo charcoal yarn has a darker color, so it can absorb the outside light that comes into contact with it. At the same time, the bamboo charcoal yarn itself also has good breathability. The use of polyester profiled yarn and bamboo charcoal yarn can ensure the overall sun protection and breathability of the fabric.

[0022] like Figures 1-3As shown, when making this fabric, composite yarn 7 is placed in a loom and woven to form a base layer 1 and a shielding layer. Several through grooves 2 are opened along the thickness direction of the base layer 1 using a laser cutting machine, and several bamboo charcoal fibers are flocked to form several light-absorbing fibers 6 using a flocking machine. Several through grooves 4 are opened along the thickness direction of the shielding layer using a laser cutting machine. Then, the support thread 5 is sewn onto the shielding layer using a sewing machine. The shielding layer is cut along the thickness direction using a laser cutting machine to form several shielding pieces 3. Finally, the shielding pieces 3 are sewn onto the base layer 1 using a sewing machine.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
