A method for pretreatment of cellulose-containing textiles characterized by applying an aqueous solution with a pH between 1 and 7 and containing at least one agent for durably changing the surface morphology of the cellulose, preferably a neutral salt.

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.

Described herein are apparatuses and methods for dyeing garments. An exemplary apparatus comprises a dye injection system configured to dispense concentrated liquid dye; a dyeing machine comprising a dyeing chamber configured for dyeing at least one garment in a dyebath; and a controller in communication with the dye injection system and the dyeing machine, wherein the controller is configured: to receive at least one garment parameter corresponding to the at least one garment; based at least in part on the at least one received garment parameter, cause the dye injection system to dispense a volume of concentrated liquid dye containing an amount of dyestuff that can be substantially absorbed by the at least one garment; and cause the dyeing machine to execute a dye cycle such that substantially all of the dyestuff in the dispensed concentrated liquid dye is absorbed by the at least one garment within the dyeing chamber.

A method for improving mycelial leather replacement compositions includes providing a mycelium material substrate, deacetylating chitin to chitosan enzymatically in a deacetylating unit, treating the deacetylated mycelial material substrate with cationic chlorohydrin in a cationization unit, combining deacetylation and cationization processes to improve the interaction with anionic aqueous treatment using an affinity enhancement mechanism, implementing a homogeneity control unit for ensuring uniform distribution of aqueous anionic treatment, creating bonding between the cationized mycelial material substrate and cellulosic fibers resulting in a positively charged fiber that maintain its charge in aqueous solution and optimizing dyeing processes for dye uptake and color fastness in mycelial leather replacement composition. Thus, the chemical penetration and homogeneous distribution of reactive sites with substantive fillers create a leather-like material in terms of texture, appearance, and performance characteristics.
