Description

Technical Field

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

[0002] Polyester is a fiber with good elasticity and high strength. The fabric is crisp and has good shape retention. It is a widely used fiber with high consumption.

[0003] Polyester fabric is woven primarily from polyester yarn. Due to the relatively tight fiber structure of polyester, the flow of air and moisture between the fibers is restricted. Furthermore, the surface of polyester fibers is relatively smooth, making it difficult for sweat to flow through the surface of the woven polyester fabric. As a result, clothing made of polyester fabric cannot evaporate sweat in time after absorbing it, affecting the comfort of wearing the clothing.

[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 quick-drying polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-drying polyester fabric includes an inner layer and an outer layer that are fixedly connected to each other. The inner layer has a plurality of grooves formed by a honeycomb structure on the side near the outer layer. The outer layer has a contact piece corresponding to the grooves on the side near the inner layer. The contact piece extends into the contact piece on the side near the inner layer. A moisture-dissipating space is formed between the outer layer and the inner layer by a plurality of support lines. The plurality of support lines are arranged on both sides of the width direction of the outer layer. The inner layer has a plurality of through holes communicating with the moisture-dissipating space. The outer layer has a plurality of through grooves communicating with the moisture-dissipating space.

[0007] The present invention is further configured such that: the contact piece is composed of a plurality of contact fibers, the length of the contact piece is the same as the length of the inner layer and is greater than the length of the groove, and the width of the contact piece is greater than the width of the groove.

[0008] The present invention is further configured such that the diameter of the through hole is greater than the width of the through groove and less than the length of the through groove.

[0009] The present invention is further configured such that: the inner layer is woven from polyester profiled yarn and polypropylene yarn, wherein the ratio of polyester profiled yarn to polypropylene yarn is 7:3.

[0010] The present invention is further configured such that: the surface layer is woven from quick-drying yarn, the support line is also made of quick-drying yarn, and the quick-drying yarn is made by twisting polyester profiled yarn and ramie yarn.

[0011] In summary, this utility model has the following beneficial effects: Since the diameter of the through hole is smaller than the length of the through groove, and the number of through holes is less than the number of through grooves, the contact area between the inner layer and the body surface is increased while ensuring the basic breathability of the inner layer. This allows sweat to be discharged from the body surface through the inner layer, shortening the time the inner layer is in a damp state. The grooves integrally formed on the inner layer reduce the thickness of the inner layer, allowing air to exchange quickly on both sides of the inner layer. Furthermore, the use of contact pieces to increase the contact area between the outer layer and the grooves further enhances the quick-drying effect of the fabric. Attached Figure Description

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

[0016] A type of quick-drying polyester fabric, such as Figure 1 and Figure 2 As shown, the fabric includes an inner layer 1 and an outer layer 2 sewn together by a sewing machine. On the side of the inner layer 1 near the outer layer 2, several grooves 3 are formed using a honeycomb weave. The grooves 3 reduce the thickness of the inner layer 1 and accelerate the exchange of air between the two sides of the fabric. On the side of the outer layer 2 near the inner layer 1, a contact piece 4 corresponding to the grooves 3 is formed. The contact piece 4 is composed of several contact fibers, which are formed by napping the outer layer 2 using a napping machine. The length of the contact piece 4 is the same as the length of the inner layer 1 and greater than the length of the grooves 3, ensuring complete contact between the contact piece 4 and the inner layer 1. During contact, a portion of the contact fleece extends into the groove 3 and contacts the inner wall of the groove 3. The width of the contact piece 4 is greater than the width of the groove 3 to ensure that the contact piece 4 can completely cover the groove 3. The contact fleece increases the contact area between the outer layer 2 and the inner layer 1. The contact fleece absorbs the sweat of the inner layer 1 and quickly dissipates it on the outer layer 2, shortening the time that the inner layer 1 is in a damp state. After the outer layer 2 is napped, the fibers inside the outer layer 2 can be better exposed to the air, accelerating the overall moisture wicking and quick-drying effect of the fabric.

[0017] Several support lines 8 are sewn onto both sides of the outer layer 2 using a sewing machine. These support lines 8 are positioned on both sides of the outer layer 2 in the width direction, creating a moisture-wicking space 5 between the outer layer 2 and the inner layer 1. This moisture-wicking space 5 prevents the inner layer 1 and the outer layer 2 from completely adhering together after fixing. The moisture-wicking space 5 allows outside air to flow stably between the inner layer 1 and the outer layer 2, carrying away sweat from the inside of the moisture-wicking fleece and ensuring its moisture-wicking effect. Several through holes 6 communicating with the moisture-wicking space 5 are cut into the inner layer 1 using a laser cutting machine, and several through grooves 7 communicating with the moisture-wicking space 5 are cut into the outer layer 2 using a laser cutting machine. The through-slot 7 provides a channel for outside air to enter the fabric, allowing outside air to enter the moisture-wicking space 5 and flow between the inner layer 1 and the outer layer 2. It can also pass through the through-hole 6 to contact the skin, ensuring the overall breathability and comfort of the fabric. The diameter of the through-hole 6 is larger than the width of the through-slot 7 but smaller than the length of the through-slot 7. The number of through-holes is greater than the number of through-holes 6, thereby increasing the amount of air entering the fabric. The fewer through-holes 6 ensure the basic breathability of the inner layer 1 while increasing the contact area between the inner layer 1 and the skin, allowing the inner layer 1 to absorb more sweat from the skin and guide it to the outer layer 2, keeping the inner layer 1 dry and comfortable for a long time.

[0018] The inner layer 1 is woven from polyester profiled yarn and polypropylene yarn. The cross-sectional shape of the polyester profiled yarn is cross-shaped. By profiled the polyester yarn, grooves are added to the yarn surface to allow air and sweat to flow through. At the same time, the good moisture-wicking properties of polypropylene fibers are used to guide sweat from the inner layer 1 to the outer layer 2, thus optimizing the quick-drying performance of the inner layer 1. The ratio of polyester profiled yarn to polypropylene yarn is 7:3. The outer layer 2 is woven from quick-drying yarn, and the support thread 8 is also set as quick-drying yarn. The quick-drying yarn is woven from polyester profiled yarn 2 and ramie yarn. The cross-sectional shape of polyester profiled yarn 2 is also cross-shaped. Ramie yarn has the characteristics of good moisture absorption and fast moisture dissipation. The use of ramie yarn allows the surface layer 2 and contact sheet 4 to stably absorb the sweat of the inner layer 1 and quickly dissipate it into the air, enhancing the overall moisture absorption and quick-drying effect of the fabric. The ratio of polyester profiled yarn 2 to ramie yarn is 7:3. Increasing the polyester yarn content can increase the overall wear resistance and durability of the fabric.

[0019] When the fabric needs to be made, polyester profiled yarn and polypropylene yarn are placed in a loom and woven in a honeycomb weave pattern to form an inner layer 1 and several grooves 3. Several through holes 6 are made along the thickness direction of the inner layer 1 using a laser cutting machine. Quick-drying yarn is placed in the loom and woven to form an outer layer 2. Several through grooves 7 are made along the thickness direction of the outer layer 2 using a laser punching machine. The outer layer 2 is then placed in a napping machine to napp and form several contact pieces 4. Quick-drying yarn is sewn onto the outer layer 2 using a sewing machine to form support lines 8. Finally, the inner layer 1 and the 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. 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.
