The plant-based composition further comprises a textile support coupled to the mixture, wherein at least a portion of the textile support is saturated by the mixture.

An aqueous polyurethane dispersion includes particles of polyurethane in water, wherein the polyurethane is derived from an organic diisocyanate, a hydrophilic monomer, a neutralizer, a chain extender, and a polyester resin, the polyester resin being a random copolymer having randomly distributed subunits of formula 1: ##STR00001##
where: R is ethylene, octylene, or decylene, a is from about 40 to about 100 mole % of the polyester resin, b is from 0 to about 30 mole % of the polyester resin, c is from 0 to about 30 mole % of the polyester resin, and a+b+c=100 mole % of the polyester resin.

The present invention relates to an adhesive silicone patch to be applied to a wearable product. The adhesive silicone patch provides the function of assisting the musculoskeletal system and ligaments for each part of the human body, the function of preventing secondary damage, the function of supporting the injured part, and the function of promoting blood circulation. In addition, the adhesive silicone patch dramatically reduces the concentration of lactic acid generated during exercise. The present invention also relates to a wearable product provided with the adhesive silicone patch. The adhesive silicone patch is applied to the inner surface of a wearable product such as clothing and includes a first functional layer. The first functional layer includes a two-component liquid silicone rubber (LSR) and a silicone-based pressure-sensitive adhesive (PSA). The LSR is composed of a main component and a crosslinking agent. The PSA is included in an amount of 50 to 200 parts by weight with respect to 100 parts by weight of the LSR.

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.

The present disclosure relates to an step artificial leather having visual penetration and a manufacturing method thereof. The artificial leather includes a thermoplastic substrate, a thermoplastic adhering layer, and a thermoplastic surface layer. The thermoplastic substrate has fiber net shape, and has visual penetration. The thermoplastic adhering layer is disposed on the thermoplastic substrate. The thermoplastic surface layer is disposed on the thermoplastic adhering layer. The thermoplastic surface layer and the thermoplastic adhering layer are transparent. Therefore, the artificial leather of the present disclosure has visual penetration effect. The product made from the artificial leather of the present disclosure has attractive appearance and diversity.

The present invention relates to a modified polyvinyl butyral material, comprising a polyvinyl butyral composite material, a filler, an anti-hydrolysis agent, a first plasticizer, zinc stearate, calcium stearate, and a polymeric dispersant; wherein the polyvinyl butyral composite material is obtained by plasticizing a composition comprising polyvinyl butyral and a second plasticizer. The present invention also relates to a preparation method of the modified polyvinyl butyral material, a modified polyvinyl butyral product comprising at least one modified polyvinyl butyral layer prepared from a material comprising the modified polyvinyl butyral material, and the preparation method of the modified polyvinyl butyral product.
