Description

Technical Field

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

[0002] Synthetic fiber fabrics are made from chemical fibers and can be pure, blended, or interwoven. The properties of synthetic fiber fabrics are determined by the properties of the chemical fibers that make them up. Synthetic fiber fabrics are characterized by high strength, high abrasion resistance, crispness, and resistance to shrinkage. These properties have led to their widespread use in clothing, home decoration, medical fields, and other areas.

[0003] When wearing clothing made of synthetic fibers for outdoor activities, the clothing will rub against objects in the external environment. Therefore, it is necessary to use fabrics with good abrasion resistance to increase the service life of the fabric. In the production of fabrics, a high weaving density is usually used to increase the abrasion resistance of the fabric. However, this method will affect the breathability of the fabric. Therefore, a new solution is needed to solve the problem that synthetic fiber fabrics cannot balance abrasion resistance and breathability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-layer polyester fabric, which reduces the contact between the inner layer and the body surface by hot pressing to make the inner layer have a wavy cross section, thereby enhancing the wear resistance of the fabric.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The double-layer polyester fabric includes an outer layer and an inner layer that are fixedly connected to each other. The cross-sectional shape of the outer layer is wavy. Several air vents are provided on the bottom surface of the trough of the outer layer. Several convex strips corresponding to the crests of the outer layer are fixedly connected to the side of the inner layer near the outer layer. The side of the convex strip away from the inner layer abuts against the inner top surface of the crest of the outer layer. The height of the convex strip is greater than the wave height of the outer layer, so that an air vent is formed between the inner layer and the outer layer.

[0006] The present invention is further configured such that: a plurality of second ventilation holes are provided on the inner layer directly below the trough of the outer layer, and the second ventilation holes are offset from the first ventilation holes.

[0007] The present invention is further configured such that: the outer layer and the vent holes are integrally formed, the outer layer is formed by alternating plain weave and perforated weave, the crests of the outer layer are woven with plain weave, and the troughs of the outer layer are woven with perforated weave.

[0008] The present invention is further configured such that: the outer layer is woven from composite yarn, the composite yarn includes composite core yarn one and composite core yarn two, the composite core yarn one is made of polyester fiber twisted and the composite core yarn two is made of nylon fiber twisted.

[0009] The present invention is further configured such that: the inner layer and the raised strip are integrally formed, the inner layer is woven by longitudinal stripe structure, the inner layer is woven by breathable yarn, the breathable yarn includes breathable core yarn one and breathable core yarn two, the breathable core yarn one is made of polyester profiled fiber twisted together, and the breathable core yarn two is made of flax fiber twisted together.

[0010] In summary, this utility model has the following beneficial effects: The fabric adopts a double-layer structure with an inner layer and an outer layer fixedly connected to each other. The outer layer adopts a sizing process, which enhances the overall wear resistance. The outer layer has a wavy interface shape. When the fabric comes into contact with an object, the crest of the outer layer will preferentially contact the object. The crest of the inner layer adopts a perforated weave to form several air holes. The raised strips on the outer layer create an air passage between the outer and inner layers. The moisture absorption performance of the raised strips is greater than that of the inner layer, which can absorb the moisture in the inner layer and reduce the time that moisture stays in the inner layer. The outer layer has air holes. The air holes and the air passage between the outer and inner layers work together to accelerate the air circulation speed on both sides of the fabric and increase the breathability of the fabric.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This double-layer polyester fabric, such as Figure 1 , Figure 2 and Figure 6 As shown, the fabric includes an outer layer 1 and an inner layer 2 that are fixedly connected to each other. The double-layered fabric can improve the abrasion resistance of the fabric. The outer layer 1 is formed by alternating plain weave and perforated weave. It is hot-pressed by two interlocking trapezoidal grooves and protrusions of hot press rollers to make the cross-sectional shape of the outer layer 1 wavy. The parts of the outer layer 1 woven with plain weave form the crests, and the parts woven with perforated weave form the troughs. Therefore, several ventilation holes 5 are evenly distributed in the troughs of the outer layer 1. The abrasion resistance of the outer layer 1 is increased by sizing the outer layer 1. The wavy cross-sectional shape of the outer layer 1 can reduce the contact area between the outer layer 1 and the body surface. When in contact with an object, the crests of the outer layer 1 will contact the object first. The plain weave weave has more interlacing times and a more stable structure than the perforated weave weave. Therefore, the crests of the outer layer 1 can protect the troughs of the outer layer 1, thus increasing the abrasion resistance of the fabric.

[0020] like Figure 3 As shown, the inner layer 2 is woven with longitudinal stripes to form several raised stripes 3 on the side near the outer layer 1. The structure of the raised stripes 3, which are integrally formed with the inner layer 2, has better stability. The raised stripes 3 correspond one-to-one with the troughs of the outer layer 1, and the side of the raised strip 3 away from the inner layer 2 abuts against the inner top surface of the crest of the outer layer 1. The height of the raised strip 3 is greater than the height of the outer layer 1, so that a breathable channel 4 is formed between the inner layer 2 and the outer layer 1. Several second breathable holes 6 are opened on the inner layer 2 directly below the trough of the outer layer 1. The first breathable hole 5, the second breathable hole 6 and the breathable channel 4 work together to accelerate the air circulation speed on both sides of the fabric and increase the breathability of the fabric. The second breathable hole 6 is staggered with the first breathable hole 5, which reduces the probability of light passing through the first breathable hole 5 and the second breathable hole 6 and directly contacting the skin surface.

[0021] like Figures 3-5As shown, the outer layer 1 is woven from composite yarn 7, which includes composite core yarn 1 8 and composite core yarn 2 9. Composite core yarn 1 8 and composite core yarn 2 9 are twisted together by a twisting machine to form composite yarn 7. Composite core yarn 1 8 is made of polyester fiber and composite core yarn 2 9 is made of nylon fiber. Both polyester and nylon fibers have good abrasion resistance, increasing the abrasion resistance between the fabric and the body surface. The inner layer 2 is woven from breathable yarn 10, which includes breathable core yarn 1 11 and breathable core yarn 2 12. Breathable yarn 10 is formed by twisting yarn 11 and breathable core yarn 12 through a twisting machine. Breathable core yarn 11 is made of polyester profiled fiber with a Y-shaped cross-section through a twisting machine. Polyester profiled fiber has good breathability and increases the breathability of the fabric. Breathable core yarn 12 is made of flax fiber through a twisting machine. Flax fiber has good moisture absorption and breathability. On the one hand, it accelerates the absorption of moisture from the inner layer 2 to the outer layer 1 and reduces the time that moisture stays in the outer layer 1. On the other hand, it further increases the breathability of the fabric.

[0022] like Figures 1-6 As shown, when this fabric needs to be made, the composite yarn 7 is fed into the loom and formed by alternating plain weave and perforated weave to form the outer layer 1 and the first ventilation hole 5. Then, a hot press is used to heat press the plain weave area on the outer layer 1 to make the cross-sectional shape of the outer layer 1 wavy. The outer layer 1 is then sized. The breathable yarn 10 is fed into the loom and woven by longitudinal stripe weave to form the inner layer 2 and the raised stripe 3. Then, a laser perforation machine is used to open the second ventilation hole 6 on the inner layer 2. Finally, the inner layer 2 and the outer layer 1 are sewn together by 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.
