摘要： The present disclosure provides a collagen-infused composite material comprising an optionally functionalized armature including a base substrate and one or more and non-woven substrates. The non-woven substrate(s) can be directly coupled to a topmost surface and/or bottommost surface of the base substrate. The material properties and/or collagen infusion capacities of the base substrate and the non-woven substrate(s) can be tailored to create a collagen-infused composite material with characteristics that mimic those of a natural leather. In some embodiments, the base substrate can be spacer fabric. In some embodiments, the armature can be functionalized to facilitate the crosslinking the collagen to the armature during one or more tanning processes.

摘要： Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins. 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.

摘要： The present invention relates to a novel PVC-free plastisol composition that cures at a temperature much lower than conventional plastisols. The plastisol composition includes an acrylate polymer; and a plasticizer mixture comprising at least three plasticizers selected from the group consisting of 2,2,4-trimethyl-1,3 pentanediol diisobutyrate, dioctyl terephthalate, dibutyl terephthalate, and benzyl butyl 1,2-cyclohexyldicarboxylate. Also disclosed is a method of applying the composition.

摘要： A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers).

摘要： The invention is directed to 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.

摘要： 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.
