Abstract

The invention provides a method for preparing dyed fabrics, comprising the following steps: obtaining tung leaves, placing them in water at 85-95°C, refluxing and extracting them to obtain tung leaf dyes; arranging the embryos in a modifier solution for Modified treatment to obtain a modified gray cloth; take another tung leaf, lay it on the modified gray cloth, arrange the modified embryo with the tung leaf in a hot press for heating Pressing, printing the tung leaf pattern on the modified gray cloth; placing the modified embryo with the tung leaf pattern in the tung leaf dye for dyeing; the dyed The above-mentioned modified embryos are arranged in a color-fixing agent solution for color-fixing treatment to obtain the product. The dyed fabric prepared by the above method has large dyeing capacity, high color fastness to washing and sun resistance.

Description

technical field

[0001] The invention relates to the field of textile printing and dyeing, in particular to dyed fabrics and a preparation method thereof. Background technique

[0002] In the field of printing and dyeing, especially in the field of clothing washing and dyeing, the pursuit of ecological protection and returning to nature has become a new fashion. People not only pursue the style and effect of ready-made clothing, but also pursue natural ecology. As more and more people pay more attention to their own health, the pursuit of green products and green consumption has become an important demand. Natural dyes have natural and elegant colors, natural fragrance, and certain antibacterial and health care functions. They are derived from nature, are harmless to human health, have good compatibility with the environment, do not pollute the environment, and are biologically Degradation, endowing people with physical and psychological comfort, is deeply favored by people....

Examples

Embodiment 1

[0035] The present embodiment provides a kind of preparation method of dyed fabric, comprises the following steps:

[0036] Step 1. Put 50 g of tung tree leaves in 300 ml of water, heat to 85° C., reflux and extract for 30 minutes, repeat twice and filter to obtain the tung oil tung leaf dye.

[0037] Step 2. Arranging the silk embryos in the MAR aqueous solution, and modifying them at 80° C. for 20-min to obtain a modified gray cloth, wherein the liquor ratio is 1:50, and the concentration of the MAR aqueous solution is 10 g / L.

[0038] Step 3, take another tung leaf, spread the tung leaf combined with the design pattern on the above-mentioned modified embryo cloth, and arrange the modified embryo with the tung leaf on the hot plate of the hot press, The press is heated so that the tung leaf pattern is printed on the modified gray cloth, such as figure 1 As shown, the hot-pressing temperature is 60°C, and the imprinting time is 30s.

[0039] Step 4. Arrange the modified emb...

Embodiment 2

[0042] The present embodiment provides a kind of preparation method of dyed fabric, comprises the following steps:

[0043] Step 1. Put 50 g of tung tree leaves in 300 ml of water, heat to 95° C., reflux and extract for 60 minutes, repeat twice and filter to obtain tung oil tung leaf dye.

[0044] Step 2. Arrange the cotton embryos in the MAR aqueous solution, and modify them at 80°C for 20 minutes to obtain a modified gray cloth, wherein the liquor ratio is 1:50, and the concentration of the MAR aqueous solution is 15g / L.

[0045] Step 3, take another oil palm leaf, spread the tung leaf combined with the design pattern on the above-mentioned modified embryo cloth, and arrange the modified embryo with the tung leaf on the hot plate of the hot press, The press is heated so that the oil palm leaf pattern is printed on the modified gray cloth, the hot pressing temperature is 110°C, and the embossing time is 60s.

[0046] Step 4. Arrange the modified embryos with the tung leaf pa...

Embodiment 3

[0049] The present embodiment provides a kind of preparation method of dyed fabric, comprises the following steps:

[0050] Step 1. Put 50 g of tung tree leaves in 300 ml of water, heat to 95° C., reflux and extract for 45 minutes, repeat twice and filter to obtain tung oil tung leaf dye.

[0051] Step 2. Arrange wool embryos in MAR aqueous solution, and modify them at 80° C. for 20 minutes to obtain modified gray cloth, wherein the liquor ratio is 1:50, and the concentration of MAR aqueous solution is 15 g / L.

[0052] Step 3, take another tung leaf, spread the tung leaf combined with the design pattern on the above-mentioned modified embryo cloth, and arrange the modified embryo with the tung leaf on the plate of the hot press, pass through the hot press Heat to make the tung leaf pattern printed on the modified gray cloth, the hot-pressing temperature is 70°C, and the embossing time is 40s.

[0053] Step 4. Arrange the modified embryos with the tung leaf pattern in the tung...
