Provided is a method of dyeing or otherwise surface treating a polymer part so as to provide a treated polymer part with a surface additive which has wash fastness with respect to alcohol solutions and therefore does not leach or transfer in response to contact with alcohol. The method includes preparing a surface treatment solution comprising a solvent and the surface additive; submerging a polymer part in the surface treatment solution for a set time period before in order to coat the surface of the part with the additive; air drying the part; vapor polishing the part by exposing an outer surface to vaporized hexafluoroisopropanol in order to bind the additive within the polymer; and finally washing the fixed coated part in a surfactant and water solution to produce a finished surface treated polymer part.

Disclosed is a method of producing a fabric product, the method comprising preparing an upper; preparing a lining fabric; layering a thermoplastic hot-melt film between the upper and the lining fabric for bonding the upper and the lining fabric; bonding a lining fabric to the upper, wherein the thermoplastic hot-melt film consists of the composition selected from the group consisting of thermoplastic polyurethane, ethylene vinyl acetate, polyamide and polyester compositions, wherein the thermoplastic hot-melt film further contains nanosilica, wherein a content of the nanosilica is 0.1 to 5.0 Parts per Hundred Resin (phr) and a size of the nanosilica is less than 100 nm.

The present invention relates to a method of producing a prepreg, in which a matrix resin is applied to a reinforcing fiber sheet, where the sheet can continuously run without clogging due to generated fuzz, even at a high running speed, and where the sheet can be efficiently impregnated with the matrix resin. The prepreg is produced by a method which includes a step of allowing a reinforcing fiber sheet to pass horizontally or slantingly through the inside of a coating section storing a matrix resin to apply the matrix resin to the reinforcing fiber sheet, where the coating section includes a liquid pool and a narrowed section which are in communication with each other, where the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the reinforcing fiber sheet, and wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the largest cross-sectional area of the liquid pool.

A process including providing a three-dimensional printing powder dispersion comprising a three-dimensional printing powder, an optional dispersing agent, and water; providing an emulsion of an organic polymeric additive; combining the three-dimensional printing powder dispersion and the emulsion of organic polymeric additive to form a mixture comprising the three-dimensional printing powder dispersion and the emulsion of organic polymeric additive; and drying the mixture of the three-dimensional printing powder dispersion and the emulsion of organic polymeric additive.
