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 interior material of a vehicle includes: a fabric layer made of a tricoat fabric, a foam layer disposed on a lower surface of the fabric layer, and an antifouling layer disposed at least between an upper surface of the fabric layer or the fabric layer and the foam layer. The tricoat fabric includes a combination of at least one of a polyurethane yarn, a high-elongation polyester yarn, or a polyester yarn.

A surface treatment agent which is an aqueous emulsion containing: (a) a fluorine-free polymer including: (i) repeating units derived from a long-chain (meth)acrylate ester monomer represented by the formula: CH.sub.2═CA.sup.11-C(═O)—O-A.sup.12, wherein A.sup.11 is a hydrogen atom or a methyl group, and A.sup.12 is a linear or branched aliphatic hydrocarbon group having 10-30 carbon atoms; (b) a surface active agent including both of a nonionic surface active agent and an anionic surface active agent, wherein the amount of the anionic surface active agent is at least 22% by weight, based on the total of the nonionic surface active agent and the anionic surface active agent; and (c) a liquid medium comprising water.

The invention involves the technical field of daily necessities, and in particular, relates to an easy-to-clean waterproof and breathable bib fabric, a preparation method, and a bib. A layer structure of the bib fabric is as follows: a hydrophobic and oleophobic surface layer, a polyurethane waterproof layer, an antibacterial and antistatic layer, and a woven layer. The hydrophobic and oleophobic surface layer has waterproof and breathable properties, is not easy to be adhered to by dirt, and is easy to clean. The polyurethane waterproof layer keeps liquids from penetrating the fabric, and the porous structure also allows for breathability. The antibacterial and antistatic layer can remove the static electricity generated by the fabric, protect the polyurethane waterproof layer from being decomposed by molds, inhibit the growth of bacteria inside the woven layer, and produce antibacterial and deodorizing effects. Further, a bib using the fabric and a preparation method are provided.

A synthetic leather according to an embodiment includes: a fibrous substrate; an adhesive layer containing a yellowing-resistant polycarbonate-based polyurethane resin and/or a yellowing polycarbonate-based polyurethane resin; and a skin layer that contains a yellowing-resistant polycarbonate-based polyurethane resin and that is laminated on the fibrous substrate via the adhesive layer. The synthetic leather has excellent oleic acid resistance.
