Description

Technical Field

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

[0002] Polyester fabric is woven from polyester yarn or polyester blended yarn, with polyester yarn making up the majority of the polyester blended yarn.

[0003] Polyester fiber has good structural strength and shape retention, so polyester fabric is a common material used to make clothing. However, polyester fiber itself has poor breathability. Therefore, when polyester fabric is used to make clothing, in order to improve the breathability of the fabric, the weaving density of the fabric is reduced or the number of pores in the fabric is increased. So when people are outdoors, outside air will pass through these pores and shine on their 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 a breathable polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable polyester fabric includes an inner layer and an outer layer that are fixedly connected to each other. A plurality of protruding strips are fixedly connected to the side of the inner layer near the outer layer. A plurality of through grooves are opened on the protruding strips and the inner layer. A plurality of support strips are fixedly connected to both sides of the outer layer along the length direction, with the protruding strips abutting against each other and arranged perpendicularly thereto. A plurality of blocking strips are fixedly connected to the side of the outer layer near the inner layer, with the protruding strips abutting against each other. Through holes are opened on the outer layer between adjacent blocking strips.

[0007] The present invention is further configured such that: the thickness of the blocking strip is the same as the thickness of the support strip, the blocking strip is composed of a plurality of blocking fibers, and the light transmittance of the blocking fibers is less than that of the surface layer.

[0008] The present invention is further configured such that: the weft yarn of the surface layer is polyester yarn one, the warp yarn of the surface layer includes polyester yarn two and bamboo charcoal yarn, and a number of polyester yarn two are followed by bamboo charcoal yarn of the same number.

[0009] The present invention is further configured such that: a plurality of air-permeable channels are formed inside the blocking strip, and the plurality of air-permeable channels are connected to a plurality of through holes and a plurality of through grooves.

[0010] The present invention is further configured such that: the inner layer is woven from polyester profiled yarn, and the cross-sectional shape of the polyester profiled yarn is cross-shaped.

[0011] In summary, this utility model has the following beneficial effects: the blocking fleece reduces the light transmittance of the fabric while allowing air entering the fabric through the through holes to pass through the ventilation channels and then through the grooves to contact the body surface, thus ensuring the breathability of the fabric itself. The blocking fleece and raised strips reduce the range of light scattering in all directions as it enters the fabric. Several blocking fleece strips abut against each other, thus blocking the opening of the grooves, thereby reducing the amount of light that can enter the fabric through the grooves and contact the body surface, and enhancing the overall sun protection and breathability of the fabric.

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

[0016] A breathable polyester fabric, such as Figure 1 and Figure 2As shown, the fabric includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The inner layer 1 has several protruding strips 3 integrally formed on the side near the outer layer 2. The inner layer 1 is configured with a protruding strip structure, and several through-grooves 4 are formed along the thickness direction of the protruding strips 3 and the inner layer 1. The through-grooves 4 provide channels for concentrated contact between outside air and the body surface, ensuring the comfort of the fabric during use. The outer layer 2 has several support strips 5 integrally formed on both sides along its length direction, abutting against and perpendicular to the protruding strips 3. The outer layer 2 is configured with a protruding strip structure, and the support strips 5 and the protruding strips 3 support the inner layer 1 and the outer layer 2. Due to the perpendicular arrangement of the protruding strips 3 and the support strips 5, a channel for outside air to flow is formed between the top surface of the protruding strips 3 and the outer layer 2. The outer layer 2 has a blocking strip 6 formed on the side near the inner layer 1, abutting against the protruding strips 3. The blocking strip 6 contains several permeable... The air passage is formed by the fact that the blocking strip 6 is composed of several blocking fibers, allowing outside air to blow and circulate between adjacent blocking fibers. Simultaneously, since the blocking strip 6 is located directly above several through-grooves 4, the air flowing between the blocking fibers can pass through the through-grooves 4. Through-holes 7 are formed along the thickness direction of the surface layer 2, located between adjacent blocking strips 6. The through-holes 7 allow outside air and light to enter the fabric. Due to the presence of the air passage, outside air can pass through the air passage and through the through-grooves 4 to contact the skin surface, ensuring the overall breathability and comfort of the fabric. Because the blocking strip 6 and the opening of the through-grooves 4 abut against each other, light needs to be absorbed and reflected within the blocking strip 6 before entering the through-grooves 4, thus reducing the amount of light that passes through the through-grooves 4 and reaches the skin surface, ensuring the overall sun protection and breathability of the fabric.

[0017] The blocking strip 6 is composed of several blocking piles. The surface layer 2 is placed in a napping machine to form several blocking piles. The thickness of the support strip 5 is reduced by decreasing the diameter of the yarn used to weave it, thus ensuring that the blocking strip 6 and the support strip 5 have the same thickness. Therefore, the bottom surface of the blocking strip 6 can stably abut against the top surface of the convex strip 3. Since the several through grooves 4 and several through holes 7 are staggered, light that shines directly into the fabric through the through holes 7 cannot pass through the through grooves 4, but will directly shine on the inner layer 1. When the light diffuses or obliquely enters the fabric, it is blocked. When light enters the fabric, it shines on a large number of barrier fibers. Some of the barrier fibers can absorb some of the light. Since the through groove 4 is opened on the ridge 3, and the ridge 3 is higher than the inner layer 1, the opening of the through groove 4 is raised. When the light enters from the through hole 7, it needs to go through a longer non-linear path to pass through the through groove 4 and shine on the body surface. During the process of light diverging inside the fabric, it will come into contact with the inner layer 1, the ridge 3 and some barrier fibers, which will cause the light to be absorbed and diffused, further enhancing the overall sun protection effect of the fabric.

[0018] The weft of surface layer 2 is set as polyester yarn one, and the warp of surface layer 2 includes polyester yarn two and bamboo charcoal yarn. Several polyester yarn two are followed by several bamboo charcoal yarns of the same quantity. Polyester yarn one and polyester yarn two not only have high structural strength but also good light resistance, utilizing the characteristics of polyester fibers to extend the fabric's lifespan. The bamboo charcoal yarn has a darker color, thus it can absorb external light shining on its surface. Due to the darker color of the bamboo charcoal yarn and the parallel arrangement of multiple bamboo charcoal yarns, a darker area can be formed on the surface of surface layer 2. To facilitate the use of bamboo charcoal yarn, darker areas are brushed to create several blocking fibers. These fibers absorb some light, reducing the amount of light passing through the slot 4. The bamboo charcoal yarn has many tiny pores, thus providing good breathability and ensuring the fabric's excellent sun protection and breathability. The inner layer 1 is woven from polyester profiled yarn with a cross-shaped cross section. This profiled shape increases the channels for airflow within the yarn, ensuring breathability and comfort during use.

[0019] When weaving this fabric, polyester profiled yarn is placed in a water jet loom and woven using a raised stripe weaving method to form an inner layer 1 and several raised strips 3. Several through grooves 4 are cut along the thickness direction of the raised strips 3 using a laser cutting machine. Polyester yarn one, polyester yarn two, and bamboo charcoal yarn are placed in a water jet loom and woven using a raised stripe weaving method to form an outer layer 2 and several support strips 5. The outer layer 2 is then napped using a napping machine to form several blocking piles. Finally, the inner layer 1 and the outer layer 2 are sewn together using a sewing machine.

[0020] 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.
