Problems solved by technology

The current natural pigments of oak husks can only be applied to cotton plants, wool and other easily dyed fabrics. The direct dyeing effect is not good, and the improvement of color fastness is mainly mordant dyeing of metal ions, which is not friendly to the environment.
The application of quercus husk dyes on real silk fabrics has not been reported at present, and it has been found in the research process that using the above methods (strong acid and iron media) will greatly damage the quality of real silk, affect the color and luster of real silk, and Not suitable for silk dyeing
[0005] With the continuous and in-depth research on Quercus husk dyes, it was found that Quercus husk dyes have significant antibacterial effects on Staphylococcus aureus, but in practical applications, it was found that when Quercus husk dyes were used in fabrics, their antibacterial properties were significantly reduced. So how can this performance be applied in fabric, make fabric also can reach better antibacterial, this is also one of the problems that the present invention needs to solve

Embodiment 1

[0021] Take 100 g of evenly pulverized Quercus husks (from Yunnan plant Quercus), the liquor ratio is 1:40, soak for 2 hours, decoct for 1.5 hours, filter, and use the same method to repeat the extraction of the obtained filter residue once, filter, and combine the filtrates , concentrated to 1 / 3 of the volume of the filtrate, placed in an oven, and dried at 65° C. to obtain Quercus quercus husk extract powder. When preparing the Quercus quercus husk dye solution, measure the powder, dilute it with distilled water to the required concentration, and sterilize it at 115°C for 30 minutes to obtain the Quercus quercus husk dye solution.

[0022] Take the Quercus quercus husk extract in Example 1, and carry out the minimum inhibitory concentration analysis of Staphylococcus aureus and Escherichia coli by double dilution method.

[0023] Pipette 1 mL of a certain concentration of Quercus hemp extract (diluted one by one by a double dilution method), 8 mL of sterile nutrient broth an...

Embodiment 2

[0032] Urea mordant dyeing process: the silk fabric (source of silk: Zhejiang Tonghui Textile Co., Ltd.) is completely soaked with water (complete soaking is for good subsequent dyeing uniformity), and then the bath ratio is 1:40, and the dye mass fraction is 5% (omf) in the hemp oak shell dye solution, dyed at 90°C for 40min; then added 2% (omf) urea mordant, mordant at 50°C for 40min, washed with water, air-dried, and dyed brown.

[0033] The picture of the silk sample after dyeing is shown in figure 1 .

Embodiment 3

[0035] Urea mordant dyeing process: soak the silk fabric completely with water, then put it into the Quercus oak shell dye solution with a liquor ratio of 1:40 and a dye mass fraction of 5% (omf), and dye at 95°C for 40 minutes; then add 2% (omf) The urea mordant was mordant at 50°C for 40min, washed with water, air-dried, and dyed brown.

Abstract

The invention discloses a dyeing process of an antibacterial type real silk dyed fabric with quercus acutissima shells. The preparation method comprises the following steps of drying and crushing cleaned quercus acutissima shells, carrying out extracting and filtering to obtain a quercus acutissima shell pigment stock solution, carrying out concentrating, drying and crushing to obtain a powdery natural quercus acutissima shell pigment; and finally, applying the quercus acutissima shell pigment to fabric dyeing, and selecting urea as a mordant, wherein the mordant not only enables the fabric toobtain more excellent dyeing color, but also promotes the antibacterial property of the quercus acutissima shell dye. The fabric dyed by the method provided by the invention is brown, and has good color fastness and a certain antibacterial effect on staphylococcus aureus.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a dyeing process of hemp oak shell antibacterial silk dyed fabric. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people are paying more and more attention to a healthy and safe way of life. A large number of pathogenic bacteria are attached to all kinds of fabrics that people wear daily, and these pathogenic bacteria are important sources of infection for many diseases; in addition, people are constantly pursuing new fabric colors. Therefore, the development of antibacterial colored fabrics has both social meaningful and economical. [0003] Quercus is also known as oak, the fruit is also called acorn, and the fruit shell is also called the shell of Quercus. in. Quercus husk is the shell of the husk tree seeds, a common nut by-product, which is not used because of its hardness, resulting...
