Problems solved by technology

[0003] At present, the raw materials, intermediates or dyes of synthetic dyes used in textiles are carcinogenic substances, which not only seriously pollute the environment, but also harm the wearers and producers, and are banned. The main source of synthetic dyes that are not currently banned is petroleum. , and the world's resources are becoming increasingly scarce, which does not meet the requirements of sustainable development

Abstract

The invention discloses a method for dyeing fabrics with persimmons, which comprises a cooked dyeing method that comprises the following steps: fresh persimmons are cut up and placed into a boiler, water is added, the fresh persimmons are boiled so as to produce dyeing liquid, the dyeing liquid is filtered, boiled and further filtered, and the obtained twice dyeing liquids are mixed for use; a fabric to be dyed is placed into a dye vat for dyeing, and taken out from the dye vat then placed into a mordant vat for mordanting, the fabric to be dyed after mordanting is taken out from the mordant vat and further placed into the dye vat for redyeing, the fabric to be dyed that finishes the dyeing is taken out from the dye vat and water cleaned, and the dyeing process is finished after softening and drying; the method for dyeing fabrics with persimmons further comprises an ingrain method that comprises the following steps: juice of the fresh persimmons is squeezed, the fabric to be dyed is placed into a dye vat with persimmon juice for dyeing, taken out from the dye vat with persimmon juice, dehydrated, laid open and dried in the sunshine; the dried fabric to be dyed is taken back, water cleaned and redyed, and the dyeing process is finished after water cleaning and drying. The two methods of the persimmon dyeing technique can realize the dyeing with colors in multiple hues, and have the advantages of environment protecting and energy saving, etc.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing industry, in particular to a preparation method for dyeing by using natural fruit persimmon as a dyeing material. Background technique [0002] Plant dyeing has existed since ancient times, but with the development of chemical science and the widespread use of chemical fuels, plant dyeing technology is almost extinct. In the vast cultural ocean of China, there is no book that records plant dyeing in detail. Plant dyeing technology relies on words and deeds. [0003] At present, the raw materials, intermediates or dyes of synthetic dyes used in textiles are carcinogenic substances, which not only seriously pollute the environment, but also harm the wearer and producers. , and the world's resources are becoming increasingly scarce, which does not meet the requirements of sustainable development. Therefore, in recent years, natural vegetable dyes have become more and more popula...
