The present invention relates to a natural dye-based wood fiber dyeing method. According to the present invention, a wood fiber produced by means of wood grinding and defibration is dyed with a vegetable-extracted natural dye without a chemical mordant being used at all and the resultant naturally-dyed wood fiber is used in the production of a wooden plate-shaped product having various colors and a uniform dyeing concentration with volatile organic compounds harmful to the human body and released when a chemical dye or paint is used for the dyeing prevented from the beginning. The natural dye-based wood fiber dyeing method according to the present invention, which is a method for dyeing a wood fiber obtained by wood being ground in a predetermined size and being subjected to defibration, includes: a step in which a plant having a pigment is put into water for the pigment to be squeezed out; a step in which a the wood fiber is put into the pigment-squeezed water and dyeing is performed based on massaging for a predetermined period of time at a room temperature and at a bath ratio of 46 to 60:1; a step in which the dyed wood fiber is dehydrated in a dehydrator; and a step in which the dehydrated wood fiber is naturally dried. 본 발명은 목재를 파쇄하고 해섬(解纖)시켜서 만든 목섬유(wood fiber)를 화학매염제를 전혀 사용하지 않고 식물계에서 추출한 천연염료로 염색해서, 천연염색된 목섬유를 사용하여 다양한 색상 및 염색농도가 균일한 목질판상제품을 제조할 수 있고, 염색에 화학염료나 안료를 사용했을 때 방출되는 인체에 유해한 휘발성 유기화합물을 원천적으로 배제할 수 있는, 천연염료에 의한 목섬유 염색방법을 제공하기 위한 것이다. 본 발명에 따른 천연염료에 의한 목섬유의 염색방법은, 목재를 일정 크기로 파쇄하고 해섬(解纖)시켜서 얻은 목섬유를 염색하는 방법인데, 상기 염색방법은, 색소를 가진 식물을 물에 넣어 색소를 우려내는 단계; 색소가 우러난 물에 목섬유를 넣어, 욕비(浴比) 46∼60:1로 하여 상온에서 일정 시간 동안 주물러서 염색하는 단계; 염색된 목섬유를 탈수기에 넣어 탈수하는 단계; 탈수된 목섬유를 자연건조시키는 단계를 거쳐서 염색하는 것을 특징으로 한다.
