[0021] The drawings are only used for illustrative description, and cannot be understood as the limitation of the patent; in order to better illustrate the embodiment, some components of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0022] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] As attached Figs. 1-3 The composite fabric shown includes a base fabric layer 1, on which storage grooves 11 are spaced apart. The storage grooves 11 are filled with insulating wadding 12, which are made of multiple polysulfone fibers with a diameter of 10-50 μm stacked together. The base fabric layer 1 is also connected to a surface layer 2. On the side of the surface layer 2 facing the storage grooves 11, there is a ventilation groove 21 perpendicular to the length direction of the storage grooves 11. The width of the ventilation groove 21 is smaller than the width of the storage grooves 11, and the ventilation groove 21 is connected to the storage grooves 11. A first moisture-wicking line 31 is also provided, which extends along the length direction of the storage grooves 11 and repeatedly passes through the base fabric layer 1, the insulating wadding 12 and the surface layer 2. A second moisture-wicking line 32 extends along the length direction of the ventilation groove 21 and repeatedly passes through the base fabric layer 1, the insulating wadding 12 and the surface layer 2.

[0024] The insulating wadding 12 in the storage tank 11 has a low moisture regain rate, remaining dry even in high humidity environments without compromising warmth. The first moisture-wicking line 31 and the second moisture-wicking line 32 together form a highly efficient moisture-wicking network, further accelerating the transfer of moisture from the fabric's interior to its surface. This helps prevent moisture buildup within the fabric and enhances its moisture-wicking properties. After absorbing moisture, the first and second moisture-wicking lines 31 and 32 can dry on the ventilation slot 21 or the fabric's surface, continuously removing moisture from the fabric's interior. Furthermore, both the first and second moisture-wicking lines 31 and 32 pass through the insulating wadding 12, which has good hydrophobicity and does not absorb moisture from either the first or second moisture-wicking lines 31 or 32. Simultaneously, the insulating wadding 12 has shape stability, helping the first and second moisture-wicking lines 31 and 32 maintain their optimal alignment, preventing them from becoming entangled after washing or bending, which would reduce the moisture-wicking effect.

[0025] The following is the manufacturing process of the thermal insulation wadding block 12:

[0026] A 22 wt% precursor solution was prepared by adding PSU particles and PAA solution to DMAc solvent, wherein the mass ratio of PSU / PAA was 8 / 2. A 15 wt% PSU / PAA / FPU spinning solution was prepared by dissolving FPU in the PSU / PAA solution.

[0027] The spinning solution is transferred to the electrospinning machine to start spinning, and the spinning process lasts for 1.5 hours, during which the perfusion speed is 5 ml / h and the spinning voltage is 30 KV. After the spinning is completed, a plurality of fiber assemblies are obtained, which are sequentially heated at 160°C, 180°C and 200°C for 30 minutes to obtain PSU / PI / FPU fiber batts. Finally, the fiber batts are cut into the shape of the storage tank 11 by laser cutting technology, and the warm-keeping batts 12 are obtained.

[0028] The fabric organization of the base fabric layer 1 is a raised stripe organization, and the double weave of the raised stripe organization is selected as 4 / 4 double weave, so as to form the storage tank 11 on the surface of the base fabric layer 1. The surface layer 2 is a plain fabric, and the ventilation groove 21 is formed on the surface by a hot pressing process.

[0029] In some embodiments, the first moisture-conducting line 31 and the second moisture-conducting line 32 are both composed of the core yarn 41 and the sheath layer 42, and the sheath layer 42 is composed of ramie fibers 421, viscose fibers 422 and polypropylene fibers 423 twisted in a spiral shape. The first moisture-conducting line 31 and the second moisture-conducting line 32 both adopt a core-sheath structure, the core yarn 41 provides a certain supporting strength, and the sheath layer 42 is twisted in a spiral shape by ramie fibers 421, viscose fibers 422 and polypropylene fibers 423 to form a porous structure, effectively increasing the moisture-conducting area and accelerating the transmission of moisture. The ramie fibers 421 have excellent moisture absorption, the viscose fibers 422 have good hydrophilicity, and the polypropylene fibers 423 provide certain strength and elasticity. The structure twisted in a spiral shape by the three can quickly absorb moisture and quickly transmit moisture to the surface of the fabric, realizing efficient moisture conduction.

[0030] In some embodiments, the core yarn 41 is internally provided with high-elasticity spandex fibers. In the sheath layer 42, the proportion of the ramie fibers 421 is greater than the proportion of the viscose fibers 422 and the proportion of the polypropylene fibers 423. The core yarn 41 internally provided with high-elasticity spandex fibers has excellent elasticity, which can maintain the stability of the moisture-conducting line when the fabric is stretched or bent, preventing the moisture-conducting line from affecting the moisture-conducting performance due to deformation. The ramie fibers 421 have good mildew resistance, and increasing the proportion of the ramie fibers 421 can enhance the mildew resistance of the fabric and avoid the occurrence of mold spots.

[0031] The high-elasticity spandex fibers are used as the core yarn 41, and the ramie fibers 421, viscose fibers 422 and polypropylene fibers 423 are fed into a vortex spinning machine. Under the action of the vortex, the ramie fibers 421, viscose fibers 422 and polypropylene fibers 423 are wrapped around the outside of the core yarn 41 in a spiral shape, thereby forming the sheath layer 42.

[0032] In some embodiments, the thickness of the thermal wadding 12 is 1.5-3mm, and the length of the thermal wadding 12 is consistent with the length of the storage groove 11. The thickness of the thermal wadding 12 is controlled to be 1.5-3mm, which not only ensures sufficient warmth, but also avoids the bulkiness of the fabric caused by excessive thickness. Such thickness can effectively block the invasion of cold air while keeping the fabric light and soft. The length of the thermal wadding 12 is consistent with the length of the storage groove 11, which ensures that the thermal wadding 12 can completely fill the storage groove 11 and fully play its role in keeping warm. At the same time, such design also makes the structure of the fabric more compact, improving the overall strength of the fabric.

[0033] In some embodiments, the thickness of the base cloth layer 1 is 1-2mm, and the side of the base cloth layer 1 away from the thermal wadding 12 is provided with skin-friendly fluff 13, and the length of the skin-friendly fluff 13 is 2-4mm. The base cloth layer 1 not only ensures the strength and durability of the fabric, but also does not increase excessive weight, improving the wearing comfort. The skin-friendly fluff 13 not only effectively blocks cold air and increases warmth, but also has soft touch and good skin-friendliness, improving the wearing experience.

[0034] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model claims.
