Abstract

The invention discloses a method for dyeing silk broadcloth by using the pollen of lily as a natural dye and belongs to the technical field of textile dyeing and finishing. The method comprises the following steps of: soaking fresh or dried dark-red lily pistil, heating and performing suction-filtration to obtain a dye solution; adding silk broadcloth fabric which is refined, and dyeing the silk broadcloth fabric; and adding different mordants for mordanting and thus obtaining silk fabric with different colors. The method has the advantages of low cost, simple process, high performance, high additional value, non-allergic and non-carcinogenic to skin, and the like; raw materials are inexpensive, easy to get, and reproducible; and taking of dyeing products is safe. Particularly, by taking plant ash as a mordant, pollution is avoided. The method is environment-friendly and energy-saving, and clothes which are made of fabric dyed by using the method are natural, environment-friendly and nonirritating to the skin.
