A kind of chip dyeing method and its application

Abstract

The invention discloses a wood chip dyeing method and its application. The wood chip is cleaned with clear water to remove surface dirt and floating dust; then placed in a hydrogen peroxide solution with a concentration of 8-12%, and soaked for 12-24 hours , and finally washed with water to remove residual hydrogen peroxide; soak 100g of Coptidis root in 1L of water for 1 to 2 hours, add 10L of water to boil for 1.5 to 2.5 hours to obtain a dark brown yellow berberine dye solution; The broken wood chips are placed in the obtained berberine dye solution for 16-24 hours of dip-dyeing treatment, taken out, rinsed, and dried to obtain golden yellow broken wood chips. Using the berberine dye solution to dye the broken wood chips into golden yellow is safe, pollution-free, simple and easy, and low in cost. Laying it around the planted plants can not only keep the soil moist, increase soil fertility, and promote tree growth, but also beautify the environment, increase visual experience, and improve its ornamental value.

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
