The method for chlorine-free anti-felting treatment of wool comprises the steps of: (a) applying a solution to the wool, the solution containing oxidizing agents based on peroxymonosulfuric sulphuric acid and a surfactant, (b) allowing the solution to act on the wool so as to complete the oxidation process, (c) washing the reaction products out of the wool, (d) treating the wool with a reducing agent, and (e) rewashing; wherein the steps are carried out continuously.

Disclosed is a method for the production of two- or three-dimensional silk products, wherein native silk fibres are formed to a two- or three- dimensional silk product and the silk product formed is subjected to a degumming step wherein a borate buffer is used as degumming agent and wherein the silk product formed is preferably contacted with an aqueous ethanol buffer prior to the degumming step.

In one aspect, the invention provides a method for making a hydrophilic-silk composition. The method includes providing at least one strand of silk fiber, treating the silk fiber with an alkaline solution to provide at least one strand of degummed silk fiber, and treating the degummed silk fiber with a treatment solution to provide a hydrophilic-silk composition. The degummed silk fiber or the hydrophilic-silk composition is further immobilized with at least one reagent to make a silk-based diagnostic composition. The invention provides a silk-based diagnostic composition made by the method of the invention, and a diagnostic device that comprises the silk-based diagnostic composition. In another aspect, the invention provides a method of making a diagnostic device. The method includes providing at least one strand of a diagnostic-fiber composition, providing at least one strand of a hydrophobic-fiber composition, inter-weaving the at least one strand of the diagnostic-fiber composition and the at least one strand of the hydrophobic-fiber composition. In one embodiment, the diagnostic-fiber composition and the hydrophobic-fiber composition are both based on silk.

Film, fibre, foam and adhesive materials are produced from soluble S-sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S-sulfonate group by treatment with a reducing agent, treatment with an acid or treatment with a common protein crosslinking agent or treatment with a reduced form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein.

Modified silk materials (i.e., incompletely carbonized silk) useful for various fields, which are produced by heating silk under comparably mild conditions to control the degree of carbonization and which have not only properties inherent in carbonized silk but also those inherent in silk itself and thus permit an enlargement in the field of application wherein the characteristics of carbonized silk are utilized; and a process for the production of the modified silk materials, which can lower the energy cost of the heating step and can be industrially carried out. Specifically, modified silk materials having various colors can be produced by heating undegummed, half-degummed or degummed silk or a composite thereof under a pneumatic pressure of 0.5 to 1.5 atm at a temperature of 150 to 500 DEG C in an air stream for a predetermined time.
摘要:
A wool or the like fibre scour including at least one of the following: (a) scouring process wherein the fibre is subjected to an acid extraction process to remove absorbed iron, and thereby to greatly improve the brightness (Y tristimulus value) of the wool; (b) a scouring process wherein a bleaching process is carried out part way through the wet process, following by drying, rewetting, and chemical reduction, therefore stabilising the bleached colour to prevent subsequent reversion in the dyebath; or (c) a scouring process wherein scoured clean fibre is dried and dusted, and then reimmersed in liquors containing detergents and dispersants, thereby effectively removing extra amounts of residual dirt. The scour produces an improved quality of fibres.

The invention relates to a method for cleaning textile fibres or other materials which comprises contacting said textile fibres or other materials with a finely-divided particulate material, the particles of which have a capacity to adsorb oil, grease and other contaminants. The invention also relates to a method for controlling parasitic infestations in animals involving the finely-divided particulate material and an apparatus for cleaning textile fibres or other materials.

Developed and provided is a method of collecting a large amount of high-quality bagworm silk threads comprising no contaminant from bagworm nests in a convenient manner and at low cost. The habit of bagworms is utilized to allow a bagworm to build a nest using solvent-soluble substances or thermally meltable substances as nest materials, followed by dissolving or melting the nest materials to separate the nest material from the bagworm silk threads, whereby only pure bagworm silk threads constituting the bagworm nest can be obtained.
