Method for dyeing rattans with plant-based black dye

Abstract

The invention discloses a method for dyeing rattans with plant-based black dye. The method is characterized by comprising the steps that (1), softening is performed, wherein the rattans are soaked in warm water firstly and then soaked in a softener solution to be subjected to ionization treatment; (2), dyeing is performed, wherein the rattans are soaked in an active agent solution for 2-3 h, and then dyeing and drying are performed and repeated for 3-4 times; (3), color protection treatment is performed, wherein the rattans are subjected to atomization treatment with a color fixative; (4), fixation is performed, wherein the fixation treatment is conducted on the rattans needing color protection by ultraviolet light and mixed mud; and (5), air-drying is performed, wherein the dye-fixed rattans are dried to the moisture content of 7%-10%, and then the rattans are coated with paraffin oil and air-dried. Compared the rattans produced through the method with a control group, the content of the dye in the rattans is increased by 61.5 mg / 100 g, the discoloration test time is prolonged by 55 h, and the bending rate is increased by 7.8%.

Description

technical field [0001] The invention belongs to the technical field of rattan processing, and in particular relates to a method for dyeing rattan with vegetable black dye. Background technique [0002] Rattan is a natural weaving material, which has smooth hand feeling, good elasticity and good processing performance. Rattan weaving is mainly made of rattan branches, rattan core or bamboo as the skeleton, and then woven with rattan bark or young rattan core. Soft and not easy to break; rattan can be processed into daily necessities and handicrafts such as rattan chairs and rattan boxes. It has become a high-end furniture and handicraft product, and is loved by more and more people. The traditional craft of rattan mainly includes processes such as drying rattan, twisting rattan, pulling rattan (planing rattan), cutting rattan, bleaching, dyeing, weaving, and painting.

The traditional craft of rattan mainly includes processes such as drying rattan, twisting rattan, pulling rattan (planing rattan), cutting rattan, bleaching, dyeing, weaving, and painting. However, chemical dyes are generally used for rattan in traditional methods, and their price is low. The effect is good, and the long-term contact of organic components with the human body will cause harm to human health; the dyeing method, the rattan cane is sprayed and colored, the thickness of the dye layer is uniform, but there are dead spots in the contact area after weaving, and the coating formed by the dipping method cane layer, it will produce uneven thickness, and there will be color difference after the finished product; and whether it is spraying or dipping dyeing, the dye only forms a coating layer on the surface of the rattan, which will dry and fall off after long-term use; and the use of vegetable dyes has a higher Safety, but high temperature treatment will reduce its activity, poor dyeing effect, and easy to fade when exposed to air for a long time
