The purpose of the present invention is to provide a health food containing silkworm cocoon-derived ingredient(s), said health food being efficacious for diabetic patients, pre-diabetic patients and those with metabolic syndrome, with the use of silkworm-derived ingredients (silkworm cocoons and mulberry leaves) that are easily available for sericulturists such as silk-raising farmers and silkworm breeders. A health food containing silkworm cocoon-derived ingredient(s) which contains, as active ingredients, fibroin obtained from silkworm cocoons and/or sericin obtained from silkworm cocoons together with mulberry leaves.
The purpose of the present invention is to provide a method for processing silk fiber to give highly durable and highly shrink-resistant silk fiber, said silk fiber little suffering from wearing or pilling even if being washed at home, maintaining the elegant gloss, smooth texture and wear comfort inherent to silk, having an extremely small shrinking percentage and, therefore, showing little dimensional change. The method for processing silk fiber, whereby washability and antifouling property are imparted to a woven silk cloth, comprises subjecting the silk fiber to a treatment for preventing degradation using a water soluble vinylsulfone derivative or a water soluble cyanuric chloride derivative as a crosslinking agent, a no-shrink treatment using a method selected from among blowing method, vacuum blowing method and sanforizing method, and a water-repellent finishing treatment using a fluorine-based water repellent agent.
Provided is a method for producing a functional polyester fiber that can be utilized in a broad range of areas, including lifestyle materials and industrial materials. By adding a reactive group to a polyester fiber and binding a crosslinking agent to the reactive group, functional agents can easily be bound to the polyester fiber. In addition, a polyester fiber with outstanding functional durability can be achieved without destroying the stability of the polyester fiber. The method for producing the functional polyester fiber involves: adding a hydroxyl group and/or a carboxyl group and/or an amino group to the polyester fiber as a reactive group; adding a crosslinking agent to the polyester fiber, to which the reactive group was added, that will react with the reaction group; and adding a functional agent that reacts with the crosslinking agent.

A process for production and hydrophobization of polyester textiles which makes it possible to produce an easy-care polyester textile which is reduced in static electrification (which is causative of the adhesion of dirt or dust in conventional dyeing and drying steps of polyester) and is therefore resistant to soil and which is improved in the friction durability in washing with an aqueous washing solution and thus exerts hydrophobicity -retaining function (soil resistance in aqueous media). A process for the production and hydrophobization of polyester textiles which comprises making both a dihalogenotriazine compound having a hydrophilic substituent and a polyamino compound coexist in dyeing a polyester textile with a disperse dye to impart a function for hydrophobization to the polyester textile.
