[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0030] As shown in the drawings, Figures 1-4 The utility model provides a technical scheme: a thin and warm polyester fabric resistant to dirt, comprising: a polyester fabric body 1, the polyester fabric body 1 is composed of a fiber layer assembly 2;
[0031] As shown in the drawings, Figure 2As shown in the figure, the fiber layer assembly 2 includes a core yarn 23 and a lower fiber layer 21 and an upper fiber layer 22 woven by the core yarn 23, the lower fiber layer 21 is located at the bottom of the upper fiber layer 22, and the lower fiber layer 21 and the upper fiber layer 22 are staggered along the X-axis and the Y-axis. By using the plain weave weaving method to weave the core yarn 23 into the lower fiber layer 21 and the upper fiber layer 22, the lower fiber layer 21 is stacked at the bottom of the upper fiber layer 22, and the lower fiber layer 21 and the upper fiber layer 22 are staggered, so that the two fiber layers form relatively complex air flow channels, and the air flows relatively slowly in these channels, which can effectively prevent heat loss through air convection, and the two fiber layers cooperate with each other, so that even if one of the fiber layers is tangled or deformed, the other fiber layer can compensate for the gap caused by tangling and deformation, thereby enhancing the warmth retention effect and making the warmth retention performance relatively stable.
[0032] Further, as shown in the figure, Figure 3 The lower fiber layer 21 and the upper fiber layer 22 are provided with connecting lines 24, and the lower fiber layer 21 and the upper fiber layer 22 are fixedly connected through the connecting lines 24. By using the connecting lines 24 to sew the lower fiber layer 21 and the upper fiber layer 22 together, the firmness of the connection between the lower fiber layer 21 and the upper fiber layer 22 is increased, and the mutual adhesion of the lower fiber layer 21 and the upper fiber layer 22 is ensured, thereby increasing the warmth retention performance.
[0033] Further, as shown in the figure, Figure 4 The core yarn 23 includes a core yarn body 25 and an outer wrapping fiber 27 outside the core yarn body 25, and the core yarn 23 is twisted by the core yarn body 25 and the outer wrapping fiber 27. Due to the relatively stable structure of the core yarn 23, compared with ordinary yarn, the weaving difficulty of the core yarn 23 is not increased too much when weaving plain fabric, and the core yarn body 25 of the core yarn 23 provides stable support, and the outer wrapping fiber 27 can be uniformly covered on the surface, so that the appearance of the fabric is smoother and more uniform.
[0034] Further, as shown in the figure, Figure 4 The core yarn body 25 is made of polyester fiber, and the outer wrapping fiber 27 is made of natural cotton fiber.

At the same time, it also solves the problem of poor moisture absorption of polyester, avoids the feeling of stuffiness and discomfort when wearing, and is conducive to improving the wearing comfort.
[0035] Further, as shown in the figure, Figure 4As shown, the cross section of the core yarn body 25 is cross-shaped, the cross-shaped cross section fiber has a larger specific surface area, and more air retention spaces can be formed inside the fiber, which can prevent heat loss and play a good heat insulation role, thereby improving the warmth retention performance of the fabric.
[0036] Further, as shown in the drawings, Figure 4 As shown, the core yarn body 25 is provided with a through hole 26 inside, and the through hole 26 is provided on the core yarn body 25 along the central axis, which reduces the weight of the fiber, reduces the overall mass of the material while maintaining a certain strength, reduces the weight of the lower fiber layer 21 and the upper fiber layer 22, avoids the polyester fabric body 1 being too heavy, and the air forms a good heat insulation layer after entering the inside of the through hole 26, which can effectively prevent heat conduction, thereby further improving the warmth retention performance of the fiber.
