Preparation method of silk-like cotton

The invention discloses a preparation method of silk-like cotton. The method comprises the following steps of water treatment, wherein water for artificial sericin making is precipitated, filtered andsterilized, and then the pH value of the water is detected and adjusted to 5.0-6.5; artificial sericin making, wherein the treated water is poured into a specific artificial sericin making machine, artificial sericin making is performed after raw materials are mixed, and prepared artificial sericin is stored in an artificial sericin sprayer; raw material selection, wherein 2.5D*51mm general two-dimensional hollow silicone and non-silicone fibers, 4D*64 mm three-dimensional hollow silicone and non-silicone fibers, 4080*2D low-melting-point filaments and a feather fabric are selected and preliminarily treated. The preparation method of the silk-like cotton has the advantages that the water for artificial sericin making is precipitated, filtered, sterilized and subjected to pH value adjustment, so that the quality o
