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...
