weaving, namely weaving the warp and the weft into a blank cloth in a set pattern, and carrying out weft straightening operation on the blank cloth by a weft straightening machine;
after-finishing, the gray fabric is soaked in the antifouling finishing liquid after being washed, kept stand for 30-60min, dried under the temperature regulation of 50 ℃, and opened and shaped;
compounding, namely flatly paving the grey cloth after the scutching and shaping on a standard horizontal plane, uniformly spraying or coating a photoinitiator on the surface of the grey cloth, and irradiating for 5-10 cycles by a photocuring instrument in a reciprocating displacement manner along the warp direction or the weft direction of the grey cloth to obtain a UV curing layer compounded on the surface of the grey cloth, so as to obtain a semi-finished product;
performing finish machining, namely cutting, edge covering and splicing the semi-finished product according to a designed style to obtain a finished product;
and (6) packaging a finished product.
6. The method for manufacturing an antibacterial and antifouling tablecloth according to claim 5, wherein: the pretreatment comprises the following specific steps:
pretreatment of hydrogen peroxide: preparing 30ml/L hydrogen peroxide, 1/L penetrant JFC1g/L and 3g/L sodium pyrophosphate into a solution with a bath ratio of 1:20, heating to 50 ℃, and soaking warp yarns and weft yarns for 45 min;
neutral protease treatment: adding sodium hydroxide to easily adjust the pH value of the solution to 7-8, standing the solution, cooling to 40 ℃, adding neutral protease with the concentration of 2-8%/owf, and treating for 30-50 min.
7. The method for producing an antibacterial and antifouling tablecloth according to claim 5, wherein: the post-finishing comprises the following specific steps:
preparing a finishing liquid, adding 1.8g of an emulsifier into distilled water, fully stirring to obtain an emulsifier aqueous solution, then adding 30g of a mixture of methyl methacrylate and lauryl methacrylate, 60g of dodecafluoroheptyl methacrylate and vinyltriethoxysilane, uniformly stirring, adding 1g of an initiator, dispersing at a high speed for 30min, finally emulsifying to obtain an anti-fouling finishing agent, and preparing to obtain the finishing liquid according to the mass of grey cloth in a bath ratio of 1: 10;
heating and dipping, namely putting the gray fabric into the prepared liquid for dipping for 10-15min, heating the liquid to 40-60 ℃ at the speed of 1-2 ℃/min, and dipping for two times, wherein the residual rate of the dipping is 60-70%;
dehydrating and curing, dehydrating the grey cloth in a squeeze roll mode, drying at the low temperature of 40-50 ℃ for 20min, and irradiating for 2-5 cycles by a photocuring instrument in a reciprocating displacement mode along the warp direction or the weft direction of the grey cloth.
8. The method for producing an antibacterial and antifouling tablecloth according to claim 7, wherein: the UV light intensity of the light curing instrument in the compounding step and the dehydration step is 300W/m 3 The wavelength is 365 nm.
