[0018] The utility model will be described in detail in combination with the drawings and examples.

[0019] A polyester fabric, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a surface layer 1 and an inner layer 2 fixedly connected to each other, and a plurality of moisture-dissipating parts 4 are fixedly connected to the end surface of the inner layer 2 close to the surface layer 1. The moisture-dissipating parts 4 are composed of a main bar 401 and a plurality of branch bars 402. The plurality of branch bars 402 are fixedly connected to the main bar 401, and the angles formed between the plurality of branch bars 402 and the main bar 401 are the same. The moisture-dissipating effect of the moisture-dissipating parts 4 is better than that of the inner layer 2. A plurality of support bars 102 are fixedly connected to the end surface of the surface layer 1 close to the inner layer 2, and the support bars 102 are offset against the end surface of the inner layer 2 close to the surface layer 1. The length between adjacent support bars 102 is greater than the length of the moisture-dissipating parts 4. The surface of the surface layer 1 has an uneven structure, and a plurality of moisture-dissipating cavities 3 are formed between the inner layer 2 and the surface layer 1. The moisture-dissipating parts 4 are located in the moisture-dissipating cavities 3. 1 and the inner layer 2 are respectively provided with a plurality of ventilation holes 101 and a plurality of ventilation holes 201, which are connected to the moisture dissipation cavity 3. After the inner layer 2 absorbs sweat from the skin, it is conducted to the moisture dissipation component 4, and the moisture dissipation component 4 with a better moisture dissipation effect is used to dissipate the absorbed sweat, and the humid gas is sent to the outside of the fabric through the plurality of ventilation holes 101 and the ventilation holes 201 on the surface layer 1 and the inner layer 2. The exchange rate of the internal and external air can be accelerated through the ventilation holes 101 and the ventilation holes 2 201, and the moisture dissipation cavity 3 of the fabric is deformed during the pressure process, which further accelerates the exchange rate of the air on both sides of the fabric. The setting of the cross section of the moisture dissipation component 4 increases the contact area between the moisture dissipation component 4 and the air, thereby improving the moisture dissipation and quick-drying effect.

[0020] like Figure 1 、 Figure 2 and Figure 3As shown, the fabric organization of the inner layer 2 is set to the warp jacquard, the ground weft and the warp weft of the warp jacquard adopt moisture-dispersing yarn, the pattern warp of the warp jacquard adopts moisture-dispersing yarn, and the plurality of moisture-dispersing elements 4 on the inner layer 2 are formed by the pattern warp. The moisture-dispersing yarn is twisted by a twisting machine from a first strand and a second strand, the first strand is twisted by a twisting machine from a plurality of ramie fibers, and the second strand is twisted by a twisting machine from a plurality of polyester profiled fibers. The cross section of the polyester profiled fiber is in the shape of a cross. Compared with a circular cross section, the surface area of the cross-shaped cross section is improved, and a plurality of grooves are formed on the surface, which improves the air permeability and moisture-dispersing performance of the polyester profiled fiber. In addition, the polyester profiled fiber has good strength, which, combined with the good moisture absorption and moisture dispersion of the ramie fiber, makes the moisture-dispersing yarn have good yarn strength and moisture-dispersing effect. The moisture-absorbing yarn is set to a core-spun yarn. The core yarn of the core-spun yarn is twisted by a twisting machine from a plurality of polyester fibers, and the covering yarn of the core-spun yarn is twisted by a twisting machine from a plurality of wool fibers. The core yarn and the covering yarn are fed into a walking spindle spinning machine, and the covering yarn is spirally wound outside the core yarn through a walking spindle spinning process to obtain the moisture-absorbing yarn. The high strength of the polyester fiber and the excellent moisture absorption of the wool fiber ensure that the moisture-absorbing yarn has good yarn strength and moisture absorption performance. The moisture absorption of the wool fiber is better than that of the ramie fiber, which can better absorb sweat. The moisture-absorbing yarn and the moisture-dispersing yarn are fed into a dobby weaving machine, and the inner layer 2 with protrusions on the fabric surface is woven according to the warp jacquard as shown in the drawings. The protrusions are used as the moisture-dispersing elements 4, and the protrusions are formed by the pattern warp. The horizontal cross-sectional shape of the moisture-dispersing element 4 is similar to a fishbone, including a main stem 401 and a plurality of branch stems 402. There is a horizontal flip angle between adjacent moisture-dispersing elements 4, and the horizontal flip angle is 180°. The included angle between the branch stem 402 and the main stem 401 on the adjacent moisture-dispersing elements 4 is complementary, and the included angle is between 30° and 60°. Since hot air rises upward, the main stem 401 and the branch stem 402 with the included angle can guide the warm airflow. The moisture-dispersing element 4 with the horizontal flip angle can make the fabric not need to consider the orientation of the branch stem 402 when making clothes, and has better practicality. The flow rate of the warm airflow inside the fabric makes it flow out to the outside of the fabric through the air permeable hole 101 or the air permeable hole 201. Figure 4 As shown in the drawings, the inner layer 2 with protrusions on the fabric surface is woven according to the warp jacquard. The protrusions are used as the moisture-dispersing elements 4, and the protrusions are formed by the pattern warp. The horizontal cross-sectional shape of the moisture-dispersing element 4 is similar to a fishbone, including a main stem 401 and a plurality of branch stems 402. There is a horizontal flip angle between adjacent moisture-dispersing elements 4, and the horizontal flip angle is 180°. The included angle between the branch stem 402 and the main stem 401 on the adjacent moisture-dispersing elements 4 is complementary, and the included angle is between 30° and 60°. Since hot air rises upward, the main stem 401 and the branch stem 402 with the included angle can guide the warm airflow. The moisture-dispersing element 4 with the horizontal flip angle can make the fabric not need to consider the orientation of the branch stem 402 when making clothes, and has better practicality. The flow rate of the warm airflow inside the fabric makes it flow out to the outside of the fabric through the air permeable hole 101 or the air permeable hole 201.

The polyester fiber can provide good yarn strength for the wear-resistant yarn, and the nylon fiber can provide good wear resistance for the wear-resistant yarn. The wear-resistant yarn is fed into the rapier loom, and the surface layer 1 is woven out in a stable manner according to the structure of the satin structure. Compared with the plain weave and twill weave, the satin structure has better air permeability. The plurality of support strips 10 on the surface layer 1 2 is embossed and formed by a silicone embossing machine, and the embossed shape is rectangular. The silicone is embossed on the surface layer 1 to form a plurality of long strips of support strips 102. The length between the support strips 102 is greater than the length of the moisture-dissipating member 4. When the support strips 102 are against the inner layer 2, since the length between adjacent support strips 102 is greater than the length of the moisture-dissipating member 4, and the position where the support strips 102 contact the inner layer 2 is located between the adjacent support strips 102, a moisture-dissipating cavity 3 can be formed between the inner layer 2 and the surface layer 1 through the support strips 102, and the moisture-dissipating member 4 is located in the moisture-dissipating cavity 3.
