Provided is a polyethylene yarn having improved post-processability, and more particularly, a polyethylene yarn which maintains excellent mechanical properties even in a harsh environment such as a high temperature to have improved post-processability such as dyeing or coating is provided.
One embodiment of the present invention provides a method for manufacturing a light-transmissive film, a light-transmissive film manufactured by the manufacturing method, and a display device comprising the light-transmissive film, the method comprising the steps of: preparing a light-transmissive resin powder; preparing a light-transmissive resin solution by dissolving a first amount of the light-transmissive resin powder in a first solvent; preparing a filler dispersion solution by dispersing a filler in a second solvent; preparing a first mixture solution by mixing the filler dispersion solution and the light-transmissive resin solution; and preparing a second mixture solution by adding a second amount of the light-transmissive resin powder to the first mixture solution and dissolving same.
