Abstract

The invention provides a bamboo fiber dyeing method based on a natural mangosteen dye. The method comprises the following specific operational steps: (1) after fresh mangosteen is eaten, cleaning the remaining fresh mangosteen shells for drying in the sun, crushing to obtain mangosteen shell powder, then putting the obtained mangosteen shell powder in an ethanol aqueous solution containing sodium hydroxide, performing ultrasonic treatment for 15-20 s, performing reflux extraction twice, combining the two obtained filtrates, adding citric acid, and concentrating to obtain the natural mangosteen dye; (2) dipping natural bamboo fibers in a 1-5% sodium hydroxide aqueous solution at a bath ratio of 1:40, soaking at the room temperature for 5-10 min, taking out the soaked natural bamboo fibers, and washing with water till the natural bamboo fibers are neutral, so as to obtain the alkaline pretreated natural bamboo fibers; and (3) soaking the alkaline pretreated natural bamboo fibers in the natural mangosteen dye at a bath ratio of 1:100, performing oscillation at constant temperature, taking out the treated natural bamboo fibers, and washing with water and drying to obtain the dyed natural bamboo fibers. According to the method, the natural mangosteen dye is adopted for dyeing treatment on the natural bamboo fibers, so that the natural bamboo fibers are endowed with an environment-friendly natural color character, the excellent environment-friendly antibacterial property is preserved, and the hand feel is unaffected.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a bamboo fiber dyeing method based on mangosteen natural dyes. Background technique: [0002] With the continuous development of science and technology, technology has brought convenience to people, but also brought corresponding side effects, and then more and more people began to pay attention to health and nature. Natural pigments are favored by people because of their safety, greenness, and non-toxicity. Natural dyes prepared from natural pigments are loved by consumers because of their elegant and soft colors and natural features. [0003] Mangosteen, also known as mangosteen, mangosteen, wind fruit, etc., is native to Indonesia and Malaysia, and is also planted in Yunnan, Guangxi, Guangdong, Fujian and other places in my country. Mangosteen is a typical tropical fruit, known as the queen of fruits. The seeds of mangosteen are arranged radially, rich ...
