A novel ultrasonic oscillation-induced sericin extraction method produces ahigh-molecular-weightsericin solution from silk cocoon threads at room temperature. In oneembodiment, unique pH variation-resistant alkaline ionic water is producedfrom a novelstrongly-alkaline ionic water generator device, wherein the unique pHvariation-resistantalkaline ionic water is subsequently utilized as a beneficial solvent thatcontributes to thefeasibility of the novel ultrasonic oscillation-induced sericin extractionmethod at roomtemperature. The high-molecular-weight sericin solution produced and coated ina gloveprovides a high coating adhesion for economical manufacturing of sericin-coated gloves,while also providing superb skin moisturizing and protection properties.Furthermore,once coated in a glove, the high molecular weight of sericin beneficiallyresists a rapidskin seepage of sericin to human skin layers, thereby acting as naturalmoisturizing factor(NMF) simulants on top of the human skin layers when the glove is worn.
