Embodiment 1

[0031] Using bright red, silk wool plain weave fabric (raw silk 20%, Eco-wash wool 80%)

[0032] The dyeing process formula is:

[0033]

[0034] According to the above dyeing formula, add reactive scarlet FN-3GL and leveling agent O to prepare the dyeing liquor, add citric acid to adjust the pH value of the dyeing liquor to 5.4-6.3; -2°C / min heating rate to 90°C, start to keep warm, add 1 / 2 of the sodium bicarbonate when keeping warm for 15 minutes, add the rest of sodium bicarbonate when keeping warm for 30 minutes, and keep warm for 60 minutes.

[0035] Take out the fabric after dyeing and carry out soaping, soaping process formula is:

[0036]

Embodiment 2

[0038] Dyeing process is identical with embodiment 1, difference is:

[0039] Rose red, silk wool plain weave fabric (raw silk 20%, Eco-wash wool 80%)

[0040] The dyeing process formula is:

[0041]

Embodiment 3

[0043] Dyeing process is identical with embodiment 1, difference is:

[0044] Light blue, silk wool plain weave (raw silk 20%, Eco-wash wool 80%)

[0045] The dyeing process formula is:

Abstract

The invention discloses a method suitable for union dyeing of a raw silk / Eco-wash wool interwoven fabric. The method comprises the steps of pretreatment, dyeing and soaping. The dyeing step is performed through adding a reactive dye and a leveling agent O according to a dyeing formula in order to prepare a dyeing solution, adding citric acid to adjust the pH value of the dyeing solution, heating the dyeing solution, adding the fabric when the temperature rises to 30 DEG C, and dyeing the fabric for a certain time while rising the temperature to a heat insulation temperature at a certain heating rate. The method effectively solves the technical difficulties of low color fastness and poor homochromatism of the raw silk / wool interwoven fabric and sericin dissolving loss of a raw silk component in the dyeing process, overcomes the shortcoming of low one-bath dyeing fastness of acidic dyes, and overcomes the shortcomings of poor alkali-bath dyeing homochromatism and large sericin dissolvingrate of reactive dyes. The method has the advantages of simple and convenient process, good homochromatism, high color fastness and wide application values.

Description

technical field [0001] The invention belongs to a dyeing and finishing method of multi-component fabrics, in particular to a method suitable for same-color dyeing of raw silk / Eco-wash wool interwoven fabrics. Background technique [0002] Silk is a natural protein fiber, known as the "fiber queen" and "the second skin of the human body". It not only has a soft and elegant appearance, but also has the inner quality of skin care and health care, and has incomparable advantages of other fibers. [0003] At present, most of the silk fabrics on the market have been degummed and soft to the touch. They are mostly used to make underwear, silk scarves, and light and thin summer clothes, etc., and the style is relatively simple. Degumming not only causes a waste of sericin resources, but also increases the burden of wastewater treatment. If the raw silk is directly dyed, sericin is fixed on the silk fibroin while dyeing, so that the silk fabric feels stiff, has a strong three-dimens...
