Embodiment 1

[0018] Raw materials are pulverized by a micro-plant pulverizer→soaked in pure water for 1h→ultrasonic water extraction, the extraction power is 250w, the extraction temperature is 60°C, the extraction material-liquid ratio is 1:20, and the extraction time is 20min→obtain a reddish-brown solution→vacuum concentration Dried, reddish-brown lotus shell pigment powder, the calculated pigment yield is 21.55%. (Pigment yield / %=mass of pigment powder / mass of lotus shell powder*100%)

Embodiment 2

[0020] Raw materials are pulverized by a micro-plant pulverizer → soaked in pure water for 2 hours → ultrasonic water extraction, the extraction power is 250w, the extraction temperature is 70°C, the extraction material-liquid ratio is 1:30, and the extraction time is 30 minutes → reddish-brown solution is obtained → vacuum concentration Dried, reddish-brown lotus shell pigment powder, the calculated pigment yield is 22.34%.

Embodiment 3

[0022] Raw materials are pulverized with a micro-plant pulverizer → soaked in pure water for 3 hours → ultrasonic water extraction, the extraction power is 250w, the extraction temperature is 80°C, the extraction material-liquid ratio is 1:40, and the extraction time is 40min → reddish-brown solution is obtained → vacuum concentration Dried, reddish-brown lotus shell pigment powder, the calculated pigment yield is 22.67%.

Abstract

The invention belongs to the field of natural pigment, and particularly relates to a preparation method and a dyeing method of natural lotus receptacle pigment. The invention adopts the following practical technical scheme: according to the preparation method of the natural lotus receptacle pigment, a lotus receptacle raw material is pulverized via a micro plate pulverizer, the pulverized lotus receptacle raw material is immersed in pure water and then is extracted by using ultrasound to obtain a reddish brown solution, the reddish brown solution is concentrated via vacuum and dried, so that reddish brown pigment powder is obtained. The invention discloses the preparation method of the natural lotus receptacle pigment, which has the advantages that the pigment is high in extraction yield; the natural lotus receptacle pigment prepared by the preparation method is used as a dye for fixing a textile, the fixed texture is natural reddish brown, has mild color and luster, has antiseptic performance, can be applicable to textiles including goggles, underwear, socks, pajamas, domestic textiles and the like, has excellent antiultraviolet performance, and is suitable for summer clothes and summer sun-shield clothes for babies, and the like.

Description

technical field [0001] The invention belongs to the field of natural pigments, in particular to a preparation method and a dyeing method of natural lotus shell pigments. Background technique [0002] Synthetic dyes have the advantages of brilliant color, good color fastness, and mass production, so they are widely used. However, synthetic dyes have caused a lot of environmental pollution due to their complex structures, various varieties, and low biodegradability. They also have defects such as carcinogenicity and allergic reactions. Today, when advocating returning to nature and protecting the environment, natural dyes have become the new darling of the textile industry because of their natural hues, soft tones, soft and non-irritating to the skin, and their own functional health benefits. [0003] The lotus shell, also known as the lotus pod, is the receptacle of the lotus of the Nymphaeaceae plant, which is in the shape of an inverted cone or funnel, and is mostly torn. ...
