Have you heard of bamboo dyeing? I believe most people have never heard of it. In fact, many bamboo products involve dyeing. There are usually three methods for dyeing bamboo products, namely chemical dyeing (or food dye). Dyeing), ink staining and natural plant staining. Most bamboo products are dyed with chemical dyes. I believe many people will have doubts about this. Why not dye them with food dyes? Combined with the understanding of the local market, industrial dyes of the same weight only cost more than ten yuan, and dyes are used. But it should be as high as a few hundred yuan, and it is natural to use that kind of dye. Next, Xiaobian will explain carefully the characteristics and frequency of the above dyes.
Chemical dyes can dye bamboo products into various colors. Chemical dyes are cheap, easy to use, and the cost is naturally low. Chemical dyes are easily bleached after staining; but the most deadly problem of chemical dyes is unhealthy. Slightly harmful to the human body. Chemical dyes are generally used on purely decorative bamboo products, but some merchants are not excluded from using industrial dyes for bamboo tableware in order to save costs.
Ink dyeing is the simplest way to dye, but it is also the most undesirable way to dye. It is easy to fade, and there is no way to dye bamboo products evenly. Very few people use it.
Plant dyeing is difficult to collect dyeing materials, and the dyeing and fixing color is complicated. It takes a long time to go back in one step, which takes a long time. If labor and cost are calculated, the cost of this dyeing method will not be lower than the cost of edible dyes; The benefits of dyeing are never faded, safe and non-toxic, and can be used on decorative bamboo products or on bamboo tableware.
The above is the current mainstream bamboo product dyeing method, I hope everyone can carefully select when buying dyed bamboo products.
