A process for the production of a composite textile article which includes at least a biopolymer layer, comprising the following steps: providing at least one textile article, in particular selected from a fiber, a yarn, a fabric and a garment; providing at least part of the textile article with at least a biopolymer layer; providing at least part of the biopolymer layer with at least a textile softening agent, to provide a composite textile article; and to a composite textile article as obtainable therefrom.

The present invention relates to a composite textile article which includes at least one textile, a biopolymer layer on the textile and a textile softening agent on at least part of the biopolymer layer. The textile article may be a fiber, a yarn, a fabric or a garment. The textile softening agent may be macro-silicone, semi-micro silicone, micro-silicone or nano-silicone. The biopolymer layer may comprise a sugar-based biopolymer, an amino acid-based biopolymer, or a mixture thereof. The composite textile article may be an elastic woven fabric or denim garment.

Provided is a process for forming a composite textile article that includes a biopolymer layer. The process includes providing a textile and contacting at least part of the textile with a culture comprising biopolymer-producing microorganisms and culturing the biopolymer-producing microorganisms to obtain a biopolymer layer on the textile. A silicone softening agent is provided to at least part of the biopolymer layer to obtain a composite textile, wherein the silicone comprises macro-silicone, semi-micro silicone, micro-silicone or nano-silicone. The composite textile article may be an elastic woven fabric or an elastic denim garment.

The present invention relates generally to compositions comprising polyelectrolytes complexes (PECs) of anionic and cationic biopolymers capable of forming barriers on fiber based materials. Also disclosed is a fibre based material with a barrier coating against oil and water, wherein the material is provided with a barrier from at least two layers formed from at least one composition comprising a polyelectrolyte complex (PEC) of a cationic biopolymer and an anionic biopolymer, The two layers result in improvements in both oil resistance and water resistance compared to the same material provided with a single layer of said at least one composition.

Provided is a composite fabric having a base fabric and at least one bacterial biopolymer layer. The base fabric is a woven fabric, and includes warp yarns and weft yarns. At least a first plurality of warp yarns and a first plurality of weft yarns form a base layer of the base fabric. A second plurality of warp yarns and/or a second plurality of weft yarns forms an additional layer of loop portions on at least one of the sides of the base fabric. The bacterial biopolymer layer is provided at least on part of the additional layer. Further provided is a process for the production of the composite fabric and a clothing article formed of the composite fabric.

An aqueous polyelectrolyte (PEC) composition for application to a fibre based material for use in obtaining a barrier coating resistant to oil and water, comprises from 0.1 to 20% (w/w) of carboxymethyl cellulose (CMC) and from 0.1 to 20% of cationic starch (CS), providing PECs with a charge ratio of 1; from 1 to 20% (w/w) of a plasticizer; and from 1 to 15% (w/w) of a pH adjusting agent selected from an acid, a buffering system and a base.

The present invention relates to a grown bioleather (1), which can be used in all sectors where animal skin and artificial leather are used, resembles a genuine leather both physically and optically, does not contain any chemicals, and has cellulose produced by microorganisms as its raw material and production method thereof. With the bioleather production method (100), a bioleather that can be named as vegan leather is obtained, which leather prevents climate change and environmental pollution by reducing carbon emissions and supports sustainable development and green economy. The said bioleather (1) involves a bacterial weaving process, can decompose in soil in a short amount of time, is highly environmentally friendly, flexible and has high tensile strength and high mechanical strength.

A wiping sheet includes a patterned part of a fiber assembling base material and a non-patterned part of the fiber assembling base material. The patterned part includes cellulose nanofiber; and the non-patterned part does not include the cellulose nanofiber.
