Description

Technical Field

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

[0002] Polyester fabric is woven from polyester yarn. Polyester fiber has good structural strength and shape retention, and is a common material used to make clothing and home textiles. Composite polyester fabric is formed by weaving polyester fabric with fibers from other materials.

[0003] Curtain fabric is a common home textile fabric made of polyester. Curtain fabric needs to have a good light-blocking effect, so the light transmittance of the fabric is reduced by increasing the thickness or weaving density of the fabric. However, the fabric woven in the above way will reduce the porosity inside the fabric, making it more difficult for outside air to pass through the fabric into the room, resulting in poor air circulation and a stuffy feeling in the room.

[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 composite polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The composite polyester fabric includes an inner layer and an outer layer that are fixedly connected to each other. A plurality of through holes are opened along the length direction of the outer layer. A plurality of contact piles corresponding to the plurality of through holes and abutting against the outer layer are fixedly connected to the inner layer. A blocking strip located on both sides of the contact piles is fixedly connected to the side of the outer layer near the inner layer. The thickness of the blocking strips is less than the height of the contact piles. The air permeability of the side of the adjacent blocking strips that is close to each other is greater than the air permeability of the side that is far away from each other.

[0007] The present invention is further configured such that: the blocking strip is composed of a plurality of blocking fibers, the blocking fibers are fixed on the outer layer by bamboo charcoal fiber flocking, and the flocking density of the blocking fibers near the contacting fibers is less than the flocking density of the blocking fibers away from the contacting fibers.

[0008] The present invention is further configured such that: two sets of ventilation holes are provided on the inner layer, and each set of ventilation holes is located on the side of the blocking strip away from the contact pile, and the distance between each set of ventilation holes and the blocking strip is the same as the width of the blocking strip.

[0009] The present invention is further configured such that the flocking density of the blocking flock on the side close to the contact flock is 500-800 flocks / square centimeter, and the flocking density of the blocking flock on the side away from the contact flock is 1000-1300 flocks / square centimeter.

[0010] The present invention is further configured such that: the inner layer is made of twisted polyester profiled yarn with a Y-shaped cross-section.

[0011] The present invention is further configured such that: the outer layer is made of polyester profiled yarn with a Y-shaped cross-section and bamboo charcoal yarn twisted together.

[0012] In summary, this utility model has the following beneficial effects: When external light enters the fabric through the through holes, it directly contacts the contact pile. A larger number of contact piles increases the surface roughness of the inner layer, allowing the light to be dispersed. By controlling the flocking density of the blocking pile, a channel for external air to enter the fabric is provided. With different flocking densities, when light is dispersed inside the fabric and shines on the blocking pile with a higher flocking density, the blocking pile can better block the light, thereby reducing the amount of light that can pass through the ventilation holes and enter the room, ensuring the overall sun protection and breathability of the fabric. At the same time, the blocking pile can absorb dust that enters the fabric through the through holes, so that the dust can be confined within a number of blocking piles and cannot move inside the fabric and enter the room through the ventilation holes.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] This composite polyester fabric, such as Figure 1As shown, the fabric includes an inner layer 1 and an outer layer 2 that are sewn together. Several through holes 3 are arranged in an array along the length of the outer layer 2, providing a channel for outside air to pass directly through it. The inner layer 1 is napped using a napping machine to form several contact piles 4 that correspond to the through holes 3 and abut against the outer layer 2. Light entering the fabric through the through holes 3 directly illuminates the contact piles 4, preventing outside light from diffusing directly between the inner layer 1 and the outer layer 2. The contact piles 4 increase the thickness of the inner layer 1, reducing the amount of light that can pass through it and enter the room. The inner layer 1 is napped using a napping machine... After the contact pile 4 is formed, the inner layer 1 is then sized. The sizing material adhering to the fabric surface increases the hardness of the inner layer 1 and the contact pile 4, thereby ensuring the stable support of the contact pile 4 to the outer layer 2. In order to prevent the sizing material from causing some of the contact pile 4 to stick together, a brushing machine can be used after sizing to loosen the stuck pile and restore the fluffiness of some of the contact pile 4, thereby ensuring the stable light diffusion of the contact pile 4. At the same time, the friction between adjacent contact pile 4 can adsorb the dust that enters the fabric through the through hole 3, preventing it from shifting inside the fabric under the action of flowing air and finally entering the room through the ventilation hole 6.

[0017] A blocking strip 5 is fixedly connected to the outer layer 2 on the side near the inner layer 1, located on both sides of the contact pile 4. The blocking strip 5 is composed of several blocking piles, which are fixed to the outer layer 2 by electrostatic flocking of bamboo charcoal fiber. The flocking density of the blocking piles on the side near the contact pile 4 is less than that on the side away from the contact pile 4. Because the distance between the blocking piles on the side near the through hole 3 is larger, the degree of obstruction of the outside air by the denser contact pile 4 is reduced, increasing the flow space of outside air inside the fabric in the initial state. Because the flocking density of the blocking piles on the side away from the through hole 3 is larger, the blocking piles at this location can restrict light. The further divergence of the threads reduces the light transmittance of the fabric. The flocking density of the blocking pile on the side close to the contact pile 4 is 500-800 piles / square centimeter, and the flocking density of the blocking pile on the side away from the contact pile 4 is 1000-1300 piles / square centimeter. The distance between adjacent blocking piles can be increased or decreased by controlling the flocking density. The length of the blocking pile is less than the length of the contact pile 4. Therefore, there is a channel for air to flow between the bottom surface of the blocking pile and the inner layer 1. Since both the blocking pile and the contact pile 4 are made of pile, the outside air can blow the blocking pile and the contact pile 4, thereby flowing inside them, allowing the fabric to take into account both sun protection and breathability.

[0018] Two sets of ventilation holes 6 are provided on the inner layer 1. Each set of ventilation holes 6 is located on the side of the blocking strip 5 away from the contact pile 4, and the distance between each set of ventilation holes 6 and the blocking strip 5 is the same as the width of the blocking strip 5. By setting the position of the ventilation holes 6, the distance that light needs to travel to enter the ventilation holes 6 can be increased. At the same time, this light will be gradually dispersed and absorbed during its flow, reducing the amount of light that can pass through the ventilation holes 6. However, the air that enters the fabric through the through hole 3 can stably pass through the ventilation holes 6 and enter the room, ensuring the overall breathability and comfort of the fabric. Since the blocking pile is fixed to the outer layer 2 by electrostatic flocking of bamboo charcoal fiber using a flocking machine, and the bamboo charcoal fiber itself is dark in color, the blocking pile can absorb the light passing between the bottom surface of the blocking pile and the inner layer 1, further enhancing the light-blocking effect of the fabric.

[0019] The inner layer 1 is made of twisted polyester profiled yarn with a Y-shaped cross-section, and the outer layer 2 is made of twisted polyester profiled yarn with a Y-shaped cross-section and bamboo charcoal yarn. After the polyester yarn is profiled, it increases the channels for air to flow through the yarn while ensuring its own light resistance. The bamboo charcoal yarn is placed in the outer layer 2, which can reduce the amount of light entering the inner layer 1 by utilizing its own light absorption effect, thus enhancing the overall sun protection and breathability of the fabric.

[0020] When weaving this fabric, polyester profiled yarn 1 is placed in a water jet loom to weave into inner layer 1. Inner layer 1 is then placed in a napping machine to nap and form several contact piles 4. Several ventilation holes 6 are then made along the thickness direction of inner layer 1 using a laser punching machine. Polyester profiled yarn 2 and bamboo charcoal yarn are placed in a water jet loom to weave into outer layer 2. Several through holes 3 are then made along the thickness direction of outer layer 2 using a laser punching machine. Several bamboo charcoal fibers are then fixed onto outer layer 2 by electrostatic flocking using a flocking machine. Finally, inner layer 1 and outer layer 2 are sewn together using a sewing machine.

All technical solutions falling within the scope of this utility model's concept are protected.
