Provided is a waterborne polyurethane dispersion. The waterborne polyurethane dispersion is prepared in the presence of a hydrophilic amino siloxane compound and exhibits good anti-stickiness while retaining superior mechanical properties. A laminated synthetic leather article prepared with said waterborne polyurethane dispersion as well the method for preparing the synthetic leather article are also provided.

The present invention refers to a process for the elaboration of a formulation based on polyurethane and mucilage of Opuntia ficus-indica with applications in the manufacturing of synthetic skin-like flexible coatings, in combination with textile substrates such as polyester, cotton, polyester and cotton10 or, with polymers such as PVC, polyurethane, among others, independently of whether it is water-based or oil-based, so that the warp of the substrate allows the generation of rolls of the coating for multiple uses and applications such as tapestry, book cover or as a substitute for coating covers for different objects that require a coating providing an external protection; this formulation has multiple applications since it has the advantage of being biodegradable and it lowers the use of contaminating plastics that contaminate the environment

The present disclosure relates to a silicone elastomeric coating composition for synthetic leather, particularly silicone-based synthetic leather, a silicone elastomeric coating (e.g., a topcoat) formed as a reaction product of the cure of the coating composition, methods of making the topcoat and synthetic leather utilizing the same and uses of synthetic leather products. The topcoat is designed to provide synthetic leather with an improved abrasion and scratch resistant topcoat.

The present invention pertains to a new shoe comprising a sole of a thermoplastic material adhered to an upper shoe with a hot melt adhesive that is applied between the sole and the upper shoe, wherein the hot melt adhesive is fused with the thermoplastic material. Advantageously, the fusion is brought about by heating the hot melt adhesive to a temperature THM such that it softens, heating the second body such that the thermoplastic material that has a melting temperature TM obtains a temperature T.sub.SUB below T.sub.M while making sure that (T.sub.HM+T.sub.SUB)/2 is equal to or higher than (T.sub.M−10° C.).

A method for producing a knitted fabric part which is knitted from at least one thread and which in one or a plurality of regions on the knitted fabric external side and/or the knitted fabric internal side is equipped with a coating, wherein, for configuring the coating, a material comprising free-flowing particles is applied in the region to the knitted fabric, said material subsequently being melted or fused by heating, whereupon the material is cooled while forming the coating.

A method for manufacturing a closed porous composite material includes 1) preparing a mixture that has 30 to 70 parts by weight of water-dispersed resin, 10 to 300 parts by weight of unexpanded thermal expansion microspheres, and 100 to 550 parts by weight of water, and stirring the mixture thoroughly; 2) preparing a carrier; 3) coating the carrier with the mixture acquired in step 1; 4) heating the carrier so that the unexpanded thermal expansion microspheres expand; and 5) repeating steps 3 and 4 multiple times to acquire a closed porous composite material. The closed porous composite material has a large number of closed cavities and polymer walls separating the closed cavities. The closed cavity is 20 μm to 800 μm in size. The ratio of a total volume of the closed cavities to a total volume of the polymer walls is greater than 16.

A method for manufacturing waterproof and breathable shoes includes manufacturing of a shoe sole, manufacturing of a shoe upper, and bonding of the shoe upper and the sole. The specific steps are as follows: S1: manufacturing of a shoe sole: subjecting shoe sole materials to plastication and mixing using an open mill, cutting into pieces according to set requirements, and compression molding to obtain the shoe sole; S2 manufacturing of a shoe upper: stacking a knitted fabric as an outer layer (1), a polyurethane (PUR) layer, and a knitted fabric as an inner layer (3) sequentially into a molding die in a nested fashion, and hot-pressing and shaping; and S3: bonding of the shoe upper and sole: bonding the shoe upper and sole for the waterproof and breathable shoes with an adhesive glue according to a size.

The invention provides aflame retardant composition comprising and ammonium polyphosphate a silane functionalised ethylene copolymer.

The present invention provides a synthetic leather including at least a base material (i), an adhesive layer (ii), and a skin layer (iii), wherein both the adhesive layer (ii) and the skin layer (iii) are formed of a urethane resin composition containing an anionic urethane resin having an anionic group concentration of 0.25 mmol/g or less, water, and an anionic surfactant. Preferably, the anionic surfactant is an alkylsulfosuccinate. The anionic group concentration of the anionic urethane resin is preferably within the range of 0.005 to 0.25 mmol/g and more preferably within the range of 0.01 to 0.2 mmol/g.

The present disclosure provides an artificial leather including a fabric layer and an ethylene-propylene copolymer (EPM) layer attached to the fabric layer. The EPM layer is an EPM composite layer including an EPM foaming layer and an EPM surface layer. The present disclosure further provides a method for manufacturing the artificial leather, and a shoe structure including the artificial leather.
