[0031] The drawings are only used for illustrative description, and cannot be understood as limitation to the patent; in order to better illustrate the embodiment, some components of the drawings are omitted, enlarged or reduced, and do not represent the size of the actual product.

[0032] It is understandable for those skilled in the art that some known structures in the drawings and their descriptions can be omitted. The technical scheme of the utility model is further described below in combination with the drawings and embodiments.

[0033] A composite anti-fouling type wrinkle-resistant fabric comprises a fabric body 1 and an anti-fouling layer 2 arranged on the surface of the fabric body 1; the fabric body 1 is provided with ridge areas 11 and flat areas 12; the ridge areas 11 are composed of densely arranged yarns and present arc-shaped raised shapes, and the ridge areas 11 are wrapped with shape memory yarns 111; the flat areas 12 are located between adjacent ridge areas 11 and are composed of relatively sparsely arranged yarns; the fabric body 1 is interwoven by warp yarns 121 and weft yarns 122, and the surfaces of the warp yarns 121 and the weft yarns 122 are fixed with anti-wrinkle microcapsules 13, and the anti-wrinkle microcapsules 13 are filled with anti-wrinkle liquid; the anti-fouling layer 2 is stacked by a plurality of nanofiber filaments 21, and the outer wall surface of the nanofiber filaments 21 is fixed with a plurality of microspheres 22.

[0034] Embodiment 1

[0035] The warp yarns 121 and the weft yarns 122 are selected from 100% polyester filaments with fineness of 150D; the shape memory yarns 111 are selected from thermally induced shape memory polyurethane yarns with fineness of 250D and recovery temperature of about 60℃, and the fabric body 1 is woven by a rapier loom.

[0036] Subsequently, the anti-fouling layer 2 is prepared by an electrospinning method; first, a core layer electrospinning solution is prepared, PA6 resin is dissolved in formic acid to prepare a 20wt% PA6 spinning solution, and ultrasonic treatment is performed for 30 minutes; then, a shell layer electrospinning solution is prepared, 5wt% SiO2 nanoparticles are dispersed in ethanol, ultrasonic dispersion is performed for 60 minutes, and then mixed with a 10wt% PVA solution.

[0037] The core layer and shell layer spinning solutions are injected into the syringes of the coaxial electrospinning equipment, and the spinning parameters are set. The nozzle voltage is 20 kV, the receiving distance is 15 cm, the core layer flow rate is 0.5 mL / h, the shell layer flow rate is 1.5 mL / h, the spinning time is 4 hours, and the receiving substrate is aluminum foil. After electrospinning, the collected anti-stain layer 2 is dried in a vacuum oven at 60°C for 24 hours.

[0038] Under the action of electrostatic field force, the coaxially sprayed core layer PA6 spinning solution and shell layer electrospinning solution are stretched into filaments. During the stretching and solvent evaporation process, the core layer PA6 solution solidifies to form a nanofiber filament 21 matrix, while due to the difference in electrical conductivity, the shell layer electrospinning solution droplets spread and solidify on the surface of the nanofiber filament 21, and finally form microspheres 22 on the surface of the nanofiber filament 21.

[0039] The main framework of the anti-stain layer 2 is a network structure formed by a large number of nanofiber filaments 21 stacked and interwoven with each other. The diameter of the nanofiber filament 21 is much smaller than that of ordinary fabric fibers, thus having a very high specific surface area and ultra-fine pore structure. The pores between the nanofiber filaments 21 are very small, much smaller than the size of liquid droplets of liquid stains. This structure can hinder the penetration of liquid stains, reduce the direct contact of stains with the fabric body 1, and reduce the adhesion of stains. The convex structure formed by the microspheres 22 on the surface of the anti-stain layer 2 can significantly reduce the actual contact area of the liquid droplets with the surface of the anti-stain layer 2. The reduction in contact area means that the adhesion of the liquid droplets to the anti-stain layer 2 is reduced, making it easier to roll or slide and less likely to spread on the surface, thereby reducing the adhesion and spread of stains.

[0040] Subsequently, the anti-stain layer 2 is placed on the surface of the fabric body 1 for hot pressing and compounding. The hot pressing parameters are set as follows: temperature 120°C, pressure 0.5 MPa, and time 30 seconds.

[0041] The wrinkle-resistant microcapsules 13 are made of chitosan by coacervation method. The coacervation method is a method of using the coacervation phenomenon of high molecular materials under certain conditions to wrap the core material dispersed in the medium to form microcapsules. Chitosan is used as the shell material of the wrinkle-resistant microcapsules 13, and a resin finishing agent is filled in the wrinkle-resistant microcapsules 13 as the wrinkle-resistant liquid. When the fabric is in the drying process and in an environment of 60°C or above, the shell material dissolves or swells significantly, causing the structure of the wrinkle-resistant microcapsules 13 to be damaged or the permeability to increase, releasing the internal solution and acting on the fabric fibers. The wrinkle-resistant liquid penetrates into the fabric fibers and forms a crosslinked network structure inside the fibers. This crosslinked network structure enhances the strength and rigidity of the fiber skeleton, making it less able to deform and more able to rebound when subjected to bending or compression, thereby reducing the formation of wrinkles. At the same time, the shape memory yarn 111 is subjected to thermal action during the drying process and returns to a straight state from a bent state, thereby eliminating wrinkles on the fabric.

[0042] Finally, the fabric body 1 passing through the hot-pressed anti-fouling layer 2 is placed in the anti-wrinkle microcapsule 13 dispersion liquid, the bath ratio is 1:20, and the room temperature is immersed for 30 minutes. The immersed fabric body 1 is taken out and dried in an oven at 45 DEG C to restore the moisture content to the normal level.

[0043] The utility model discloses a double effect of convex strip organization structure and shape memory yarn 111, effectively promote the wrinkle recovery ability of fabric. Convex strip organization structure provides structural support, resists the wrinkle production, and shape memory yarn 111 occurs shape recovery under specific conditions, initiatively eliminates the wrinkle, realizes the lasting flat effect. Meanwhile, the setting of anti-wrinkle microcapsule 13, through slow-release anti-wrinkle liquid, further enhances the wrinkle resistance of fabric. Meanwhile, through the anti-fouling layer 2 of nanometer fiber silk 21 and microsphere 22 construction, fabric is endowed with excellent hydrophobic and oleophobic properties, effectively resists water-based and oily stains. Compared with the traditional fluorine series anti-fouling finishing, the utility model is more inclined to the application of environment-friendly materials and technology in material selection and process design, such as environment-friendly shape memory polymer, nanometer material, microcapsule slow-release technology, reduces the influence on environment and human health.

[0044] Obviously, the above-mentioned embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the implementation mode of the utility model. For ordinary skilled in the art, on the basis of the above-mentioned explanation, other different forms of changes or changes can be made. Here, it is unnecessary and impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
