Embodiment Construction

[0024] A kind of natural dyeing process of double-layer fabric is characterized in that: concrete steps are as follows:

[0025] (1) Pretreatment: Biological enzyme pretreatment on the double-layer fabric;

[0026] (2) Rinse: Rinse the pre-treated double-layer fabric, add 0.6-2g / liter of neutral soaping agent to the water during rinsing, raise the water temperature to 50-70°C, and discharge the soap after rinsing for 30-40 minutes Lotion;

[0027] (3) Pre-mordanting: place the double-layer fabric in an aqueous solution with mordant added, the mordant is controlled at 3-6g / liter, the temperature is controlled at 40-55°C, and soaked for 20-30 minutes;

[0028] (4) Dyeing: Add 0.8~5g / liter of natural plant dye and 1~5g / liter of mordant according to the depth of the color. After heating up the dye solution for 20 minutes, soak the double-layer fabric in the mordant solution for 30~90 minutes;

[0029] (5) Cleaning: Wash the soaked double-layer fabric with clean water at room tem...

Abstract

The invention relates to the technical field of dyeing, and particularly relates to a natural dyeing process of double fabric. The natural dyeing process of the double fabric comprises the following concrete steps: (1) pretreatment; (2) rinsing; (3) pre-mordanting; (4) dyeing; (5) cleaning; (6) drying; (7) dipping; (8) airing and sizing. Compared with the prior art, shortage of synthetic dyestuff materials is compensated by using the renewability of a natural plant and excellent dyeing property and health-care performance of vegetable dyes. The double fabric is environment-friendly in the dyeing process, and free of pollution on a production environment in the entire production process; the dyeing product does not generate any harm to health of a human body, and does not generate bad effects on the human environment; the printing and dyeing processes are ecological; no metal mordant is needed in the dyeing process. Thus, the requirements of modern ecological textiles are achieved; the dyed fabric has excellent color fastness; the textile has good anti-ultraviolet property.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a natural dyeing process for double-layer fabrics. Background technique [0002] Textiles are essential daily necessities for human beings, and the properties and quality of their dyes are directly related to human health and social development. The textile industry is a huge light industry in the world. It pollutes the environment seriously and endangers human health. The biggest source of pollution in the textile industry comes from dyeing and finishing. The European Union has announced that 23 intermediates containing azo dyes in textiles are not allowed to be used. If any of them are detected, it is a substandard product and cannot enter the EU market. China is a big textile country, and the export of printed and dyed textiles accounts for about 28% of the country's total export value. The disadvantages of synthetic dyes have attracted great attention from governments and sc...
