A method for making colored leaf veins for handicrafts

Abstract

The invention discloses a method for producing colored veins for artware. The method comprises the following steps of 1, leaf selecting, wherein high-quality leaves are selected; 2, enzymolysis, wherein after the leaves are boiled with clear water, compound enzyme is added for enzymolysis; 3, bleaching, wherein after veins obtained after enzymolysis are aired to be half-dry, light-shielded bleaching is conducted with a hydrogen peroxide solution; 4, dying, wherein after the veins obtained after bleaching are cleaned, the veins are aired to be half-dry, and dying is conducted with a natural pigment, so that the dyed veins are obtained; and 5, shaping, wherein the colored veins are dried and shaped. According to the method for producing the colored veins for the artware, a compound enzymolysis method is adopted, and after being dried, the veins can still maintain to be soft and is not likely to be fractured; and later-stage processing and shaping of the artware can be conducted conveniently. Meanwhile, safety in the production process is improved; required production time is shortened; and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of handicraft processing, and in particular relates to a method for making colored veins for handicrafts. Background technique [0002] The veins are the visible veins on the leaves and are the supporting structure of the leaves. After the mesophyll is removed, the veins of the leaves present an unbelievably beautiful structure, which can be prepared into various handicrafts with ornamental value through dyeing and shaping. [0003] Usually the method of preparing leaf veins is mainly alkaline hydrolysis, using sodium hydroxide to prepare 0.5-10% alkaline water to boil the leaves, corrode the mesophyll, and use the natural fermentation method to use the fermentation of microorganisms in nature to rot the mesophyll, and use active Yeast fermentation removes the mesophyll. Alkaline hydrolysis uses a strong alkali sodium hydroxide, which is a dangerous chemical. Improper operation is easy to cause injury, and...

AI Technical Summary

Problems solved by technology

Alkaline hydrolysis uses a strong alkali sodium hydroxide, which is a dangerous chemical. Improper operation is easy to hurt, and it needs to be stored properly, otherwise it will easily absorb moisture and agglomerate, which will affect the use

The natural fermentation method takes too long, generally takes 10-30 days. During the natural fermentation process, sewage and unpleasant odors are produced due to the corruption of the mesophyll

The yeast fermentation method is slightly shorter than the natural fermentation method, but it also takes 7-10 days

In addition, the leaf veins prepared by the above method tend to become hard and brittle after drying, and are not easy to shape. Not only the quality and shape are not good, but also the serious waste of products is caused, which increases the cost.

On the other hand, the colored leaf vein products on the market are mainly colored with pigments. These pigments are made by artificial chemical synthesis methods, which are inedible and harmful to the human body.
