Method for dyeing mulberry silk fabric by using camphor tree pericarp pigment

Abstract

The invention relates to a method for dyeing a mulberry silk fabric by using camphor tree pericarp pigment. A mordanting solution with the mass concentration of 1%-7% is prepared, the mulberry silk fabric is put into the mordanting solution for pre-mordanting treatment, a camphor tree pericarp pigment extracting solution is added for dyeing at a bath ratio of 1: 50 and a dyeing temperature of 60 DEG C-100 DEG C, and after the dyeing is finished, the mulberry silk fabric is taken out, washed, and aired to obtain the dyed mulberry silk fabric. According to the method, fruits of camphor trees commonly used for urban landscaping are used for pigment extraction to obtain the dyeing solution, on one hand, waste of dropped camphor tree fruits and pollution of the fruits to the environment are reduced, on the other hand, the camphor tree fruits have many health-care effects on a human body, and the pigment extracted from the fruits is used for dyeing the fabric and is beneficial to the healthof the human body. The adopted dyeing solution is safe and environmentally friendly, the dyeing method is easy to operate, the dyeing effect is good, and the color fastness is high.

Description

technical field [0001] The invention relates to a method for dyeing mulberry silk fabrics, in particular to a method for dyeing mulberry silk fabrics with camphor tree peel pigment, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Mulberry silk fiber is a high-grade textile raw material, the fiber is thin and soft, and has good strength and stretchability. As a natural protein fiber, the fabric made of it has noble and elegant appearance, elegant and soft luster, smooth and delicate texture, elegant, smooth and breathable clothing, and is favored by consumers. Therefore, it is widely used in the field of clothing manufacturing and textiles. [0003] Most of the mulberry silk products currently on the market need to be dyed to obtain other colors. Common dyeing methods include the use of chemical dyes and the use of natural dyes. When chemical dyes are used for dyeing, due to the coloring requirements of chemical dyes, high ...

Problems solved by technology

When chemical dyes are used for dyeing, due to the coloring requirements of chemical dyes, high temperatures above 90°C are required during the dyeing process, which consumes a lot of energy, and because chemically synthesized dyes usually contain harmful substances, the pollution in the dyeing process will be serious and the after dyeing Mulberry silk may also have adverse effects on human health

In recent years, there have been more and more studies on extracting natural products from plants and applying them to textiles. Using natural dyes for dyeing, the color of the fabric will be more natural, and usually dyed at a lower temperature, so the requirements for equipment are also It is lower, and the energy consumption will also be reduced, but the dyeing effect of natural dyes is poor, and there are many problems such as low color fastness, not rich colors and color systems, and insufficient supply

[0004] Camphor tree, also known as camphor tree, is an excellent greening tree, street tree and shade tree in southern cities of my country. Camphor tree will produce a large amount of camphor tree fruit every year, and camphor tree fruit has many health care effects on human body, but the effective effect on camphor tree fruit is at present. Utilization is seldom, thereby the camphor tree fruit shedding that produces every year is extremely wasteful, and fruit shedding pollutes urban environment
