Embodiment 1
[0024] The first step: natural pomegranate peel extraction
[0025] Extract fresh or dried natural pomegranate peels with deionized water. The extraction process is as follows: the solvent mass is 30 times the mass of pomegranate peels, the extraction temperature is 100°C, and the extraction time is 120 minutes;
[0026] Step 2: Filtration of pomegranate peel extract
[0027] The pomegranate peel extract is coarsely filtered with a 80-mesh metal screen to remove the filter residue;
[0028] The third step: centrifugation of pomegranate peel extract
[0029] Use a centrifuge to centrifuge the pomegranate peel extract at room temperature, with a rotating speed of 5000 rpm and a centrifugation time of 15 minutes, and collect the supernatant to obtain a transparent and clear pomegranate peel extract;
[0030] Step 4: Direct dyeing of wool and silk fabrics with pomegranate peel extract
[0031] The technical parameters of direct dyeing of wool fabric and silk fabric by using pom...
