Method for coloring surface of bamboo strip

Abstract

The invention discloses a bamboo strip surface coloration method, which is performed according to the steps of: production of bamboo strips, in which a bamboo material is cut into sections and hacked, and is scraped with bamboo green skin and bamboo yellow liner to be processed into the bamboo strips; cooking, in which dirt on the surfaces of the bamboo strips is removed, the bamboo strips are cooked in boiled water, and grease, sugar and bamboo pulp of the bamboo strips are removed; drying treatment, in which the bamboo strips are taken out and then are baked until the water content is between 8 and 12 percent; coloration, in which the bamboo strips are soaked into a boiled coloring liquid for 60 to 220 minutes, and the coloring liquid comprises the following components (according to weight percentage): 2 to 7 percent of ferrous sulfate, 0.1 to 0.25 percent of direct black, and the balance being water; and drying treatment, in which the bamboo strips are taken out and then are baked until the water content is between 8 and 12 percent. The method has the advantages of safe and simple production process, low production cost, and firm coloration.

Description

technical field [0001] The invention relates to a method for coloring the surface of bamboo strips. Background technique [0002] Bamboo is processed into bamboo strips, which can be woven into various production tools or daily necessities, and are widely used in decoration. But, because the color and luster of bamboo itself has determined bamboo strip to be close to light yellow color, caused the handicraft color that bamboo strip weaves or bamboo strip production is monotonous. In order to solve the problem of the single color of bamboo strips, there are two methods in the existing technology: 1. Bamboo strips are baked at high temperature and carbonized; 2. Paint is sprayed on the surface of bamboo strips; 3. Dyeing. Its disadvantages are: the temperature and time during carbonization are not easy to control, and it is easy to cause safety hazards such as fire, the paint layer of spray paint is easy to fall off, the dyed color cannot penetrate into the inside of the bamb...

Problems solved by technology

But, because the color and luster of bamboo itself has determined that bamboo strip is close to light yellow color, has caused the handicraft color of bamboo strip weaving piece or bamboo strip production to be monotonous.

In order to solve the problem of the single color of bamboo strips, there are two methods in the existing technology: ① Bamboo strips are baked at high temperature and carbonized; ② Paint is sprayed on the surface of bamboo strips; ③ Dyeing

Its disadvantages are: the temperature and time during carbonization are not easy to control, and it is easy to cause safety hazards such as fire, the paint layer of spray paint is easy to fall off, the dyed color cannot penetrate into the inside of the bamboo strips, and the production cost is relatively high.
