Description

Technical Field

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

[0002] Polyester fabric utilizes the high strength and good abrasion resistance of polyester fibers, resulting in high strength, abrasion resistance, and good elasticity. By adding fibers with different properties and adjusting the proportion of different fibers, the functional focus of polyester fabric can be varied. Polyester fibers have poor moisture absorption and breathability, and a higher proportion of polyester fibers will lead to a decrease in the moisture absorption and breathability of the polyester fabric. Therefore, it is necessary to design composite polyester fabrics to ensure that the polyester fabric has good moisture absorption and breathability while also having good structural strength. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide composite polyester fabric.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite polyester fabric, including a base layer, wherein a plurality of moisture-absorbing strips are provided on both end faces of the base layer, the moisture-absorbing strips are arranged linearly along the warp direction of the base layer, a plurality of moisture-dissipating holes are opened on the base layer, the moisture-dissipating holes are located between adjacent moisture-absorbing strips, and a plurality of obliquely arranged moisture-absorbing strips are fixedly connected to one side surface of the base layer, some of the moisture-absorbing strips abut against the moisture-absorbing strips and form a plurality of protrusions on the base layer.

[0005] The present invention is further configured such that: a plurality of the moisture-absorbing strips 2 are arranged in a linear array on the base layer, the spacing between adjacent moisture-absorbing strips 2 is greater than the spacing between adjacent moisture-absorbing strips 1, and a plurality of moisture-absorbing strips 1 and a plurality of moisture-dissipating grooves with horizontal cross sections in the base layer are formed, and some of the moisture-dissipating holes are located in the moisture-dissipating grooves.

[0006] The present invention is further configured such that the horizontal projection surface of the second moisture-absorbing strip completely overlaps or partially overlaps with the horizontal projection surface of some of the moisture-dissipating holes.

[0007] The present invention is further configured such that: the fabric structure of the base layer is a double-sided jacquard structure, the first warp and weft yarns of the double-sided jacquard structure are nylon-polyester-viscose yarns, the second warp yarn of the double-sided jacquard structure is a viscose yarn, the yarn count of the viscose yarn is less than the yarn count of the nylon-polyester-viscose yarn, and a plurality of the moisture-absorbing strips are formed by the second warp yarn of the double-sided jacquard structure.

[0008] The present invention is further configured such that: the second moisture-absorbing strip is sewn from moisture-absorbing yarn, the moisture-absorbing yarn is made by twisting several bamboo fibers and several nylon profiled fibers, and the cross section of the nylon profiled fibers is cross-shaped.

[0009] In summary, this utility model has the following beneficial effects: The plurality of moisture-absorbing strips 1 and 2 arranged in different array directions on the base layer increase the rate at which sweat soaks into the fabric after absorption. Furthermore, the moisture-absorbing strips 1 and 2 increase the surface area of ​​the fabric, thereby improving the overall moisture-wicking area and performance. The protrusions formed by the overlapping of the moisture-absorbing strips 1 and 2 reduce the contact area between the fabric and the skin. The obliquely arranged moisture-absorbing strips 2 and 1 form a mesh structure, which can improve the overall structural strength and tensile strength of the base layer. The moisture-wicking holes located in the moisture-wicking grooves ensure good breathability of the fabric. The moisture-wicking holes, which are completely or partially blocked by the moisture-absorbing strips 2, increase the contact area between the moisture-absorbing strips 2 and the outside air, thus improving the moisture-wicking effect of the moisture-absorbing strips 2.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Composite polyester fabric, such as Figure 1 , Figure 2 and Figure 3 As shown, the material includes a base layer 1. Several moisture-absorbing strips 2 are arranged on both ends of the base layer 1, linearly arrayed along the warp direction of the base layer 1. Several moisture-dissipating holes 4 are opened on the base layer 1, located between adjacent moisture-absorbing strips 2. Several obliquely arranged moisture-absorbing strips 3 are also fixedly connected to one end of the base layer 1. Some of the moisture-absorbing strips 3 abut against the moisture-absorbing strips 2 and form several protrusions 301 on the base layer 1. By using several moisture-absorbing strips 2 and 3 arranged in different array directions on the base layer 1, the wetting speed of sweat on the fabric after absorption is increased. Furthermore, the moisture-absorbing strips 2 and 3 increase the surface area of ​​the fabric, thereby improving the overall moisture-dissipating area and performance. The protrusions 301 formed by the overlapping of the moisture-absorbing strips 3 and 2 reduce the contact area between the fabric and the skin. The obliquely arranged moisture-absorbing strips 3 and 2 form a mesh structure, which can improve the overall structural strength and tensile strength of the base layer 1.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the fabric structure of the base layer 1 is a double-sided jacquard weave. The yarns used to weave the base layer 1 are nylon-polyester-viscose yarn and viscose yarn. The nylon-polyester-viscose yarn serves as the first warp and weft yarns of the double-sided jacquard weave, while the viscose yarn serves as the second warp yarn. The viscose yarn is thicker than the nylon-polyester-viscose yarn and is used to form the moisture-absorbing strips 2 on both sides of the base layer 1. Due to the higher proportion of viscose fibers in the viscose yarn, its moisture absorption and breathability are superior to those of the nylon-polyester-viscose yarn. As the main yarn forming the base layer 1, the nylon-polyester-viscose yarn primarily provides better functionality to the base layer 1. The viscose yarn is fed into the jacquard loom and woven into the base layer 1 according to the double-layer jacquard structure. Because the viscose yarn is relatively thick, it will form several moisture-absorbing strips 2 arranged along the weft direction on both sides of the base layer 1. After obtaining the base layer 1 with several moisture-absorbing strips 2, several moisture-dissipating holes 4 are laser-drilled on the base layer 1 by a laser punching machine or a laser burnishing machine. The laser-drilled holes are located between two adjacent moisture-absorbing strips on the base layer 1. The moisture-dissipating holes 4 are linearly arrayed along the warp direction of the base layer 1. The opening of several moisture-dissipating holes 4 can effectively improve the air exchange efficiency on both sides of the base layer 1.

[0017] Several moisture-absorbing strips 3 on the base layer 1 are sewn together using moisture-absorbing yarn. This yarn is made by twisting several bamboo fibers and several nylon profiled fibers. The nylon profiled fibers have a cross-shaped cross-section, which creates grooves on the surface of the fibers, increasing their bulk and moisture absorption. The nylon profiled fibers also possess good abrasion resistance and elasticity. Combined with the cooling sensation, good moisture absorption, and breathability of bamboo fibers, the moisture-absorbing yarn exhibits both excellent abrasion resistance and moisture absorption. The moisture-absorbing yarn is sewn together using an automatic sewing machine. The automatic sewing machine, which is installed on the base layer 1, has its sewing direction intersecting with the length direction of the moisture-absorbing strip 2. The sewing path of the automatic sewing machine is straight. The moisture-absorbing yarn is sewn onto the base layer 1 by the automatic sewing machine, forming several obliquely arranged moisture-absorbing strips 3. When the moisture-absorbing strips 3 intersect with the moisture-absorbing strip 2, some of the moisture-absorbing strips 3 float on the surface of the moisture-absorbing strip 2, forming several protrusions 301. When the base layer 1 with several moisture-absorbing strips 3 is used as the side facing the skin, the several protrusions 301 on its surface can reduce the contact area between the base layer 1 and the skin, thus achieving the effect of preventing sticking.

[0018] During the sewing process, several moisture-absorbing strips 3 and 2 form several horizontally parallelogram-shaped moisture-absorbing grooves 5 on the base layer 1. The moisture-absorbing strips 2 pass through moisture-absorbing holes 4 during sewing, resulting in some strips 2 not intersecting with the holes 4, and some strips completely or partially blocking one end of the hole 4. This structure increases the contact area between the moisture-absorbing strips 2 at the opening of the hole 4 and the air, improving the moisture-absorbing effect of the localized area and thus enhancing the fabric's quick-drying performance. The strips 2 that do not intersect with the holes 4 primarily serve to ensure the structural strength of the base layer 1. The several moisture-absorbing strips 3 and 2 form a mesh structure on the base layer 1, thereby improving the fabric's tensile strength and structural strength.

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.
