The invention relates to a planar textile substrate comprising on a surface a coating that contains a water-activated adhesive, said adhesive representing an aqueous dispersion of the following composition.

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.

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.

An object of the present invention is to provide a composition capable of realizing an excellent matt tone of a leather surface in a case of being used as a synthetic leather or an artificial leather, a sheet-shaped molded body, an artificial leather, and a manufacturing method of a sheet-shaped molded body. The composition of the present invention is a composition used for a synthetic leather or an artificial leather, the composition containing a polypeptide, a fibrous substance other than the polypeptide, and, a plasticizer.

The present invention relates to a process for the production of a dyed biopolymer comprising the steps of providing at least one biopolymer-producing microorganism, providing at least one dye-producing microorganism, culturing said at least one biopolymer-producing microorganism to produce at least a biopolymer, and culturing said dye-producing microorganism wherein said dye-producing microorganism produce at least a dye suitable to dye at least part of said biopolymer, whereby a dyed biopolymer is obtained. The present invention also relates to a dyed biopolymer, to process for the production of a dyed composite article comprising at least the dyed biopolymer and to articles comprising the dyed biopolymer.

The present invention provides a process for the production of a fabric having a unique appearance and the fabric so obtained. Also provided is the clothing articles, i.e. garments, including the fabric. More particularly, the present invention relates to a process for producing a woven fabric having a unique, e.g. “used” (i.e. worn-out) or “multi-shaded” appearance and the process includes a step of providing a woven fabric with a layer of bacterial biopolymer, dyeing at least part of the fabric together with the biopolymer layer, and then removing at least part of the bacterial biopolymer layer from the fabric.

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.

Coated and expanded, nanofiber structures are provided and methods of use thereof.

The present invention relates to a process for producing an electrically conductive composite textile article, comprising a step of providing at least part of a textile article with a biopolymer, wherein at least part of said biopolymer comprises an electrically conductive material. The invention also relates to an electrically conductive composite textile article comprising a textile article and a biopolymer, wherein at least part of said biopolymer is provided with an electrically conductive material; and to a yarn, or a fabric, or a garment, consisting of, or essentially consisting of a biopolymer that can be produced by a microorganism, wherein at least part of said biopolymer is provided with an electrically conductive material.

Coated and expanded, nanofiber structures are provided and methods of use thereof.
