Abstract

The invention discloses a natural lotus leaf dye and a dyeing and color fixing method, and mainly relates to the technical field of natural dyes. The natural lotus leaf dye is prepared by the following steps: weighing 1 part by weight of dry lotus leaves, and mashing; measuring to take 30-50 parts by weight of water, and heating to be boiled; adding the mashed lotus leaves into boiling water, keeping boiling for 50-70 minutes, and filtering to obtain the natural lotus leaf dye. The natural lotus leaf dye is good in color fixing property, stable in dyeing, uniform in color, free of pollution and capable of achieving full circulation of plant dyeing.

Description

technical field [0001] The invention relates to the technical field of natural dyes, in particular to a natural lotus leaf dye and a dyeing and fixing method. Background technique [0002] Since chemical dyes were introduced to China in 1902, they quickly replaced the traditional Chinese plant dyeing process with its advantages of complete color spectrum, simple technique, good color fastness, and low cost, and the traditional plant dyeing process gradually declined. However, with the development of the economy, the environmental pollution is becoming more and more serious, the disadvantages of chemical dyes are becoming more and more obvious, industrial wastewater leads to ecological imbalance, and chemical carcinogens such as aromatic amines seriously affect human physical and mental health. China has a vast territory, rich plant species, complete dye chromatograms, superb dyeing technology, and a long history of plant dyeing culture. Lotus dyeing is a branch of plant dyei...
