[0003] Common polyester fabrics have the advantages of being easy to wash and dry, not easy to wrinkle, and having good stiffness, but the macromolecules of polyester fibers have a symmetrical structure, the phenylene groups are very rigid, and lack hydrophilic groups, so they are prone to static electricity during use. In daily life, the static electricity generated on the surface of polyester fabrics easily absorbs dust and microorganisms, affecting the performance of the fabric. Utility Model Content

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] Combination Figure 1 This embodiment is described in detail. An antistatic mixed polyester fiber cloth includes: a composite easy-to-remove layer 1, a base fabric layer 2 and an antistatic layer 3; the base fabric layer 2 is arranged between the easy-to-remove layer 1 and the antistatic layer 3; the easy-to-remove layer 1 is interwoven with warp yarn and weft yarn, the warp yarn is cationic polyester filament, and the weft yarn is celes staple yarn; the base fabric layer 2 is interwoven with polyester-cotton blended yarn. Specifically, the polyester-cotton blended yarn is a polyester / cotton 65 / 35 blended yarn.

[0018] The cationic polyester filament has excellent antistatic properties. In a dry environment, polyester fibers are prone to generate static electricity due to friction, which causes the fibers to adsorb each other and form pills, affecting the quality and appearance of the textiles, and are prone to adsorb dust. Since the cationic polyester filament has a positive charge on its surface, it can effectively reduce the frictional electrification phenomenon between the fibers, thereby reducing static electricity accumulation, improving antistatic properties, and reducing dust adsorption.

[0019] The celis staple yarn is spun from celis biodegradable fiber, and has the advantages of soft cotton feel, quick moisture absorption and drying, not easy to pilling, and dyeable at room temperature and pressure, etc. The easy-to-remove dirt layer is woven using celis staple yarn as the weft yarn, and the hydrophilic group and pore structure of the celis biodegradable fiber are utilized to make it have excellent hydrophilicity, so when the sample meets water, the celis biodegradable fiber interacts with water, the interfacial tension of the fiber / water phase is weak, and the interfacial tension of the oil / fiber phase is strong, and the dirt is easily separated from the fabric through external mechanical action, thereby achieving a good easy-to-remove dirt function.

[0020] Furthermore, the dirt-removing layer 1 is a two-up-one-down twill weave. Compared with the honeycomb weave with a concave-convex effect, the two-up-one-down twill weave has a relatively flat surface, is not easy to hide dirt, and has better dirt-removing performance.

[0021] Furthermore, a hydrophilic and easy-to-remove finishing agent is attached to the side of the easy-to-remove layer 1 away from the base fabric layer 2. The hydrophilic and easy-to-remove finishing agent adopts a special modified polyether polyester, which has both hydrophilicity and oleophobicity, so that the surface oil stains of the fabric can be easily washed off when the fabric is washed with water, achieving an easy-to-remove effect. The hydrophilic and easy-to-remove finishing agent cooperates with the easy-to-remove layer 1, and the fabric can still maintain a good easy-to-remove effect even after multiple washings.

[0022] Furthermore, the antistatic layer 3 is sericin modified antistatic polyester fabric.

[0023] The preparation method of the sericin modified antistatic polyester fabric is as follows: firstly, the polyester is subjected to an alkali reduction treatment, a hydroxyl reaction site is introduced on the surface of the polyester fabric, and then methacrylic anhydride is used for grafting reaction on the surface of the polyester fabric to obtain a vinyl-containing polyester fabric; at the same time, vinyl is introduced into the sericin to improve its reaction activity, and under the catalytic action of ultraviolet light, the sericin is grafted on the surface of the polyester fabric through free radical polymerization. Sericin is a protein macromolecule rich in serine, aspartic acid and glycine. Most of the polypeptides have polar side groups, such as hydroxyl groups, carboxyl groups, etc. The spatial structure is mainly irregular curling and has good hydrophilicity. The discharge of wastewater containing sericin not only increases the COD value of the wastewater, harms the natural environment, but also causes a great waste of natural resources. Sericin has good hydrophilicity and biosafety. Therefore, the modification of polyester fabric with sericin realizes the recycling of sericin on the one hand, and improves the antistatic performance of polyester fabric by utilizing the hydrophilic hygroscopicity of sericin on the other hand.

[0024] Embodiment 2

[0025] Combination Figure 2 This embodiment is described in detail. The difference from the first embodiment is that a thermal insulation layer 4 is provided between the base fabric layer 2 and the antistatic layer 3 .

[0026] Furthermore, the thermal insulation layer 4 is a sodium alginate carboxylated cellulose composite aerogel.

[0027] Specifically, the preparation process of the sodium alginate carboxylated cellulose composite aerogel is as follows: a carboxylated cellulose nanofiber suspension with a mass fraction of 4.0% and glutaraldehyde with a mass fraction of 5% for the carboxylated cellulose nanofibers are prepared into glutaraldehyde cross-linked aerogel; a sodium alginate and glutaraldehyde cross-linked aerogel with a mass fraction of 4% are mixed in a ratio of 4:6, and calcium carbonate with a mass fraction of 10% for the sodium alginate and glutaraldehyde cross-linked aerogel is added, and the aerogel is prepared by the calcium carbonate ice template method. The surface of the sodium alginate carboxylated cellulose composite aerogel is relatively uniform, without obvious cracks and loose void structures, which is conducive to locking the internal static air and has a stable warming effect.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
