High-efficiency healthy environment-friendly dyeing method for reed stalks

Abstract

The invention especially relates to a high-efficiency healthy environment-friendly dyeing method for reed stalks, belonging to the technical field of dyeing. The method comprises the following concrete steps: (1) immersing the reed stalks in an aqueous solution of maltitol, picking up the reed stalks, carrying out draining until no water drop drips, putting the reed stalks into a freezer for freezing treatment, taking out the reed stalks, treating the reed stalks with constant-temperature steam, then taking out the reed stalks, and carrying out cooling at room temperature so as to obtain pretreated reed stalks; and (2) subjecting the pretreated reed stalks to electric field treatment, immersing the reed stalks in a dyeing agent, taking out the reed stalks, carrying out draining until no water drop drips, and then drying the reed stalks. The dyeing agent is prepared from the following raw materials: fresh rose petals, fresh mint leaves, fresh violet petals, fresh rhododendron petals, cellulase, nanometer calcium carbonate, nanometer silica, goat milk, taurine, polyvinyl alcohol, ethyl acetate and water. The method provided by the invention effectively improves a dyeing rate and dyeing stability, allows the dyed reed stalks to have strong anti-fading ability, effectively enhances the strength and toughness of reed stalks, improves the usage performance of the reed stalks, and increases the utilization rate of resources.

[0002] Reed, perennial aquatic or wet-growing tall grass, grows beside irrigation ditches, riverbanks and swamps, etc. Reed stalks can also be made into handicrafts. There are many types of reed weaving, such as mats, mats, baskets, baskets or foils. The finished products have unique craftsmanship and distinctive local color retention; in addition, the color of reed woven products is also an important factor that determines the impression of consumers. In order to improve the decorative effect and product value of reed woven products, reed stems should be dyed to improve The use value of reed woven products meets people's requirements for color diversity; however, the current dyeing technology of reed stems is not ideal, not only is it not easy to color, but it is easy to fade after dyeing, and most of the dyeing materials used are harmful to human health. impact, the smell is pungent, therefore, there is an urgent need to invent a method for dyeing reed stalks to solve the above problems
