water repellent finishing method of automobile kenaf interior material and automobile kenaf interior material thereby

摘要

The present invention relates to a water repellent treatment method of the automotive kenaf interior material and the interior material. For example, interior seating materials are formed on the headlining and sidewalls of automobiles. The present invention relates to a method for water repellent treatment on a kenaf material, which is an automotive interior material installed in an automobile headlining and the like, and a interior material material thereby. The main constitution of the present invention for achieving the object of the present invention, Kenap filament immersion step of immersing the kenaf filament of the form of thread in a immersion liquid containing a water repellent; And a drying step of drying the immersed kenaf filament, wherein the immersion liquid containing the water repellent comprises 95-98 wt% of water and 2-5 wt% of an emulsion water repellent, and 100 wt% of the emulsion water repellent. When the chloroalkyl acrylate copolymer 15-18% by weight, tripropylene glycol 2-6% by weight, emulsifier 2-3% by weight, the rest is characterized in that the water, the heat treatment step after the drying step To further include, the heat treatment temperature in the heat treatment step is characterized in that the drying for about 30 seconds to 2 minutes at 150 degrees Celsius to 160 degrees Celsius.
