Abstract

The invention discloses a process for dyeing a silk fabric by using a tuber fern wood dye. The process specifically comprises the following steps: cleaning a tuber fern, naturally airing and then crushing to obtain tuber fern residues, pouring an alcohol solution in the tuber fern residues for performing ultrasonic standing to obtain a primary supernate extracting solution of the tuber fern, then performing high-speed centrifugation on the extracting solution of the tuber fern, removing remained tuber fern residues to obtain a secondary supernate, adding small-molecular weight chitosan in the secondary liquid supernatant, uniformly mixing and then vacuumizing and concentrating to obtain the tuber fern wood dye, padding the refined silk fabric in the tuber fern wood dye, dyeing, after taking out and drying, placing in a steam box for performing mordant-containing steam treatment, taking out and naturally airing to obtain the silk fabric dyed by tuber fern. According to the process, the raw material range is wide, the operation is simple; the prepared silk fabric is high in dyeing rate and color fastness, and is suitable for industrialized production.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, and in particular relates to a process method for dyeing silk fabrics with kidney fern plant dyes. Background technique: [0002] Vegetable dyes (Vegetable dyes) use the roots, stems, leaves, fruits and flowers of natural flowers and trees as raw materials, and the pigments extracted therefrom are used as dyes. Most of the plant dyes are important materials, non-toxic and harmless. The color of the fabric dyed by plant dyes is natural, the color fastness is good, and it also has health care functions such as antibacterial and insect repellent. Since ancient times, plant dyes have been widely used in dyeing processes. In recent years, with the enhancement of people's awareness of energy conservation and environmental protection, ecological textiles prepared with plant dyes have become more and more popular. [0003] The colors in plant dyes are usually prepared from plant extracts such as ...
