Wood chip dyeing method and application of dyed wood chips

Abstract

The invention discloses a wood chip dyeing method and an application of dyed wood chips. The method comprises steps as follows: the wood chips are cleaned up with clear water, and dirt and floating dust on the surfaces are removed; the wood chips are put in a hydrogen dioxide solution with the concentration of 8%-12% and are soaked for 12-24 h, and finally, the wood chips are cleaned with clear water to remove hydrogen dioxide residues; 100 g of coptis roots are put in 1 L of water and soaked for 1-2 h, then 10 L of water is added for boiling for 1.5-2.5 h, and deep brownish yellow berberine dye liquor is obtained; the treated wood chips are put in the berberine dye liquor for dip dyeing treatment for 16-24 h, then the wood chips are taken out, washed and air-dried, and golden yellow wood chips are obtained. The wood chips are dyed into golden yellow through the berberine dye liquor, the method is safe, pollution-free, simple and easy, and the cost is low. When the golden yellow wood chips are laid around transplanted plants, effects of soil moist maintenance, soil fertility increase, tree growth promotion and the like are realized, meanwhile, the environment can be beautified, the visual perception is increased, and the ornamental value is improved.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to a method for dyeing wood chips. Background technique [0002] Wood chips have been widely used as organic mulch in foreign urban greening. Among them, the organic mulch is made of various organic biological materials through crushing and processing, and then laid around the planted plants to keep the soil moist, increase soil fertility, inhibit weeds, and promote tree growth. Organic mulch can be made from a wide variety of materials, including shredded bark, wood chips, shredded leaves, compost, pine needles, sawdust, wheat straw, straw, and fruit husks. At present, there are as many as 15 kinds of organic mulch materials used in foreign urban greening, but they are mainly bark pieces and wood chips. From the perspective of the source of organic mulch, one type is made by professional organic mulch processing enterprises using forest harvesting residues. The mulch p...

Problems solved by technology

The current existing product is the organic mulch of Carolanti plants, which is unique in the market due to the introduction of American mulch production technology, high product cost, and technical monopoly

[0003] The traditional wood chip dyeing is dyed with dye, the color after dyeing is too bright, or it is difficult to achieve the expected dyeing effect, especially it is difficult to dye golden yellow, and it is difficult to meet people's aesthetic standards in the end, so it is not widely accepted. application

[0004] The use of vegetable dyes for dyeing can effectively solve the problem of chemical dye pollution, but there is no standardized production process and industry standards for vegetable dyes, and even the same dye plant, due to different origins, climates or collection times, will cause vegetable dyes The pigment content, pigment composition and pigment color are very different, so the dyeing reproducibility is poor

In practical application, most vegetable dyes are used in fabric dyeing, but the problem of poor color fastness is common

And, utilize vegetable coloring agent to dye wood and also have no report
