Methods of using of natural or engineered proteins such as collagen to form tanned and/or crosslinked fibers suitable for a wide range of textile manufacturing processes, including non-woven, woven and knitted fabrics. In particular, described herein are methods of forming collagen fibers formed from cell-cultured materials by forming a solution of collagen, tanning agent and in some variations cross-linker, and shortly thereafter, extruding collagen fibers. Also described herein are collagen fibers formed by these methods.

Disclosed herein are synthetic leathers, artificial epidermal layers, artificial dermal layers, layered structures, products produced therefrom and methods of producing the same.

A method for processing plant material for converting such material into a product with leather-like properties comprises chemical processing, or tanning, of the plant material to convert same into a feather-like material. The method comprises at least the steps of chemical processing, drying, and welding. The end-product is characterized by its similarity to leather and may be used in diverse areas of industry, such as clothing, footwear, bags, accessories, furniture, inter alia.

A method of preparing recycling leather sheets comprise: pre-processing where leather wastes are neutralized and fatliquoring agents are adhered; separating leather fibers from the leather wastes that has undergone the pre-processing; mixing the separated leather fibers with fibers for improving a tensile strength of the separated leather fibers; and forming sheets by combining the mixed leather fibers and raw fabrics for floor. The method of preparing recycling leather sheets in the present invention may reduce environmental pollution by preparing recycling leather sheets through physical combination without using adhesives.

Use of probiotic technology to support tanners to reduce waste and increase the value of by-products reducing the need of synthetic chemicals, improving the quality of effluents and reducing the carbon footprint to the environment. Probiotics or beneficial microorganisms are used to obtain biochemicals through a controlled fermentation of natural ingredients. The result of the process is a consortium of metabolites including viable probiotic microorganisms with properties very similar to traditional leather auxiliaries extensively needed during leather production, eliminating or reducing the need for use of toxic chemicals and compositions.

There is provided a process for tanning animal hide comprising treating an animal hide with at least one tanning agent and exposing the treated hide to a dose of ionising radiation of from 1 to 500 kJ/kg wherein the ionising radiation is in the form of a charged particle beam.
