Embodiment 1

[0017] (1) Treatment of persimmons: choose unripe green persimmons, wash them, dry them, and crush them to 0.8-1.2cm 3 After the granules were obtained, the obtained green persimmon granules were soaked in deionized water for natural fermentation, the water temperature was controlled at 35°C, the fermentation time was 4 days (96h), and the water consumption was just enough to submerge the green persimmon granules.

[0018] After the fermentation is completed, filter, and the obtained filtrate is a solution of green persimmon extract, and freeze-dry the obtained filtrate to obtain green persimmon extract powder, which is sealed and protected from light;

[0019] (2) Dyeing process: add the green persimmon extract powder obtained in step (1) into deionized water for dilution to obtain a uniform dilution, and control the mass concentration of the green persimmon extract in the dilution to be 1%, and adjust The pH value of the diluent is 4; immerse the clean linen bed sheet in th...

Embodiment 2

[0021] (1) Treatment of persimmons: choose unripe green persimmons, wash them, dry them, and crush them to 1.0-1.5cm 3 After the granules are obtained, the obtained green persimmon granules are soaked in deionized water for natural fermentation, the water temperature is controlled at 32°C, the fermentation time is 4 days (96h), and the water consumption is just enough to submerge the green persimmon granules.

[0022] After the fermentation is completed, filter, and the obtained filtrate is a solution of green persimmon extract, and freeze-dry the obtained filtrate to obtain green persimmon extract powder, which is sealed and protected from light;

[0023] (2) Dyeing process: add the green persimmon extract powder obtained in step (1) into deionized water for dilution to obtain a uniform dilution, and control the mass concentration of the green persimmon extract in the dilution to be 1%, and adjust The pH value of the diluent is 5; immerse the clean linen bed sheet in the obta...

Embodiment 3

[0025] (1) Use the conventional "alcohol extraction" method to extract green persimmons. The specific steps are: select unripe green persimmons, wash the green persimmons, dry them, and crush them to 0.8-1.2cm 3 After the granules are obtained, the green persimmon granules obtained are added to reflux extraction with a pH value of 9 and a volume percentage concentration of 50% ethanol aqueous solution. The mass ratio of the green persimmon granules to the ethanol aqueous solution is 1:40; the extract is heated to 90° C., Insulate for 1.5 hours; filter and freeze-dry the obtained filtrate to obtain green persimmon extract powder, and store in a sealed and dark place;

[0026] (2) The dyeing process in this embodiment is consistent with the dyeing process in Example 1, and the dyed fabric is very light pink, and the specific performance is shown in Table 1.

Abstract

The invention belongs to the field of fabric dyeing, and in particular relates to a fabric dyeing process adopting a persimmon extract as a dye and an application of a related dyed fabric. According to the process, persimmons are subjected to special process treatment to obtain a dyeing solution, and the dyeing treatment of a fabric by using the dyeing solution can be performed without a mordant and can achieve a good dyeing effect. Adverse effects of heavy metal ions in the mordant on human bodies and environments are avoided; and compared with 'alkali extraction', 'alcohol extraction' and the like in the prior art, the fabric dyeing process disclosed by the invention is simple in treatment process of the persimmons and low in cost, and after dyeing, the dyeing fastness of various fabrics can achieve good use characteristics.

Description

technical field [0001] The invention belongs to the field of fabric dyeing, in particular to a fabric dyeing process using persimmon extract as a dye and the application of related dyed fabrics. Background technique [0002] With the strengthening of people's awareness of environmental protection and the increasing attention to human health, the negative effects of some synthetic dyes on human health and ecological environment have attracted more and more attention. Early studies have shown that there are more than 100 commonly used dyes that may produce carcinogens. In 1994, developed countries such as Germany promulgated regulations to ban these dyes. Not only that, with the consumption of the earth's oil resources, the problem of raw materials for synthetic dyes has gradually been exposed. Therefore, researchers have begun to devote themselves to the development of "natural and environmentally friendly dyes" and "environmentally friendly and clean dyeing and finishing pr...
