Method for preparing dye by plum peel and application thereof

Abstract

The invention discloses a method for preparing dye by plum peel and application thereof, which is characterized in that industrial salt or acetin and water are used for preparing the fixative of dye. The method for preparing the dye comprises the following steps: peeling the plum by a fruit huller; separating out the plum peel; pulping the plum peel into fine slurry by a beater; adding 6-8 times of water in a reaction kettle; and filtering impurities by a filter screen to prepare dye solution. The application of preparing dye by the plum peel is characterized in that natural cellucotton, hemp, silk and the like which are to be dyed are dipped into the prepared fixative and are slowly decocted with slow fire for about one hour, and then the obtained product is cleaned; and the cleaned natural fiber is dipped ito plum dye solution and is slowly decocted for one hour until the fiber is dyed into red.

Description

technical field [0001] The invention relates to a method for preparing dyes from plum peels and its application. Background technique [0002] There are four main aspects of textile and clothing affecting human safety and health during wearing or use: First, free formaldehyde on fabrics can cause headaches, weakness, body temperature changes, sensory disturbances, irregular perspiration, rapid pulse, dermatitis, skin allergies, etc. symptom. The second is that some aromatic amine intermediates left in the process of printing and dyeing synthesis of azo dyes have carcinogenic effects on the human body. Third, heavy metals that may remain in textiles include: mercury, nickel, chromium, lead, arsenic, etc. These heavy metals mainly come from dyes, catalysts and clothing buttons, zippers and other accessories in the printing and dyeing process. If the content of heavy metals in clothing is too high, it will not only weaken people's immune function and induce cancer, but also ...

Second, some aromatic amine intermediates remaining in the process of printing and dyeing synthesis of azo dyes have carcinogenic effects on the human body

It should be pointed out that in general, azo dyes themselves will not have harmful effects on the human body, but some azo dyes synthesized with carcinogenic aromatic amine intermediates will interact with the normal metabolic process of the human body after long-term contact with human skin. Combining with the substances released in the body, a reduction reaction occurs to break the azo group, and regenerate carcinogenic aromatic compounds. These compounds are reabsorbed by the human body, and after activation, the structure and function of human cells are changed, thereby transforming into human diseases. Predisposing factors, which increase the susceptibility of carcinogenesis
