Chemically modified seacell fibres, wound dressing made therefrom and preparation method thereof

A chemically modified cellulose/alginate co-spun (seacell) fiber, a wound dressing made therefrom and a preparation method thereof. The seacell fiber is subject to a chemical modification through which a hydrophilic carboxymethyl group is introduced into the cellulose structure making the chemically modified seacell fiber more absorbent. The modified cellulose has a degree of substitution of 0.05-0.5; the seacell fiber has a linear density of 0.5-5 dtex and a fiber length of 5-180 mm. The seacell fiber has hygroscopic and gel-forming properties, while retaining its active ingredient of algae particles.

Method for biofabricating composite material

The invention is directed to a method for producing a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrils and provides strength, elasticity and an aesthetic appearance to the composite material.

Method of collecting bagworm silk thread

Developed and provided is a method of collecting a large amount of high-quality bagworm silk threads having 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.

Method for the chlorine-free anti-felting treatment of wool

The method for the chlorine-free anti-felting treatment of wool comprises the steps of: f) applying a solution onto the wool, wherein the solution has an oxidizing agent based on peroxomono sulphuric acid and a tenside, g) exposing the wool to the solution in order to complete the oxidation process, h) washing out the secondary reaction products from the wool, i) treating the wool using a reduction agent and j) post-washing,
wherein the steps are carried out continuously.

Method for making a biofabricated material containing collagen fibrils

Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins which are recombinantly produced and which contain substantially no 3-hydroxyproline. The collagen or collagen-like proteins are isolated from animal sources, or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.
