Problems solved by technology

At present, some dye companies in countries such as India, Italy, and Germany are developing and producing natural vegetable dyes, but there are serious problems in obtaining vegetable dyes. Due to the low pigment content in dye plants, they must be picked in large quantities if they want to obtain enough dyes. and cutting down plants, causing damage to the ecological environment, which violates the original intention of using plant dyes to achieve environmental protection
In addition, there are also some main problems in textile dyeing of plant natural dyes: ①Poor dyeing repeatability
The vast majority of commonly used natural dyes are plant dyes. Even if it is the same plant, the composition and color of the pigment will be affected by different origins, climate conditions and different collection times, making it diffic

Embodiment 1

[0025] (1) Preparation and extraction of biochrome

[0026] Preparation of pigment by microbial fermentation process: culture medium formula: peptone 16g / L, glycerin 20g / L, MgSO 4 1.2g / L, NaCl 2.0g / L, Gly 2g / L, shake flask liquid volume 50mL / 250mL (V / V), inoculate Serratia marcescens jx-01 (CGMCC 4074) red pigment strain 5% (V / V ), pH 5.7, culture temperature 28°C, shaker speed 170r / min, culture 72h. Take the above fermented liquid and put it at 10000r·m -1 Centrifuge for 10min, discard the supernatant, add acetone to the sediment for 10min, and extract the extract at 10000r·m -1 After centrifuging for 10 min, the supernatant was rotary evaporated to constant weight, which was the red pigment solid of prodigiosin.

[0027] (2) Preparation of dye

[0028] Red pigment solid, diffusing agent sodium methylene bis-naphthalene sulfonate and zirconium beads with a diameter of 1.43mm are mixed in a mass ratio of 1:0.2:100 and put into a grinding cup to stir evenly, and then use a ...

Embodiment 2

[0048] The dyestuff prepared by the present invention dyes polyester fabric

[0049] Dyeing conditions: the amount of dye is 1% (o.w.f), the liquor ratio is 1:30, the dyeing temperature is 100°C, and the dyeing time is 45 minutes.

[0050] Dyeing process: pour water into the dye vat, heat to 50°C, weigh the dye, add a small amount of hydration material (to disperse the dye evenly in water), add to the dye vat, run for 2 minutes, add fabric, heat up to 80°C at 2°C / min, Reduce the heating rate, raise the temperature to 100°C at 1°C / min, dye for 40 minutes, release the residual liquid, wash twice with warm water, take it out, dehydrate, and dry.

[0051] (4) Dyeing effect

[0052] The color fastness and antibacterial properties of the dyed fabrics were tested, and the test results are shown in Table 4.

[0053] The test method of fastness to washing is based on GB / T3921·1-1997, and the rating is evaluated according to GB / T25O-1995; the determination of fastness to rubbing is ba...

Abstract

The invention relates to a biological dye containing prodigiosins. The dye is prepared through mixing prodigiosins, a nonionic and/or ionic surfactant compound agent and zirconium beads with a mass ratio of 1:0.2:100, and a dispersion system has a mean particle size of less than 1 mum in water. The biological dye is mainly suitable for dying various chemical fibers. Dyed fabrics have the characteristics of good washing fastness and rub fastness, and brilliant color, and also have a favorable anti-bacterium performance with an anti-bacterial rate of more than 90%. The dye, which has the advantages of simple extraction technology, ecological environmental protection and convenient preparation, is the biological dye with good performances and has a good application prospect.

Description

technical field [0001] The invention relates to a composition for dyeing, in particular to a biological dye containing prodigiosin, a preparation method and its application in textile dyeing. Background technique [0002] Under the influence of the global wave of green environmental protection, natural plant dyeing has returned to people's vision. Natural dyes have the characteristics of ecological balance: natural and bright color, high safety, non-toxic and have certain nutritional value and pharmacological health effects, as bio-renewable resources, the production process is environmentally friendly, and there is no three-waste treatment problem, so it has re-emerged in the dye industry. focus on. At present, some dye companies in countries such as India, Italy and Germany are developing and producing natural plant dyes, but there are serious problems in obtaining plant dyes. Because the pigment content in dye plants is relatively small, if you want to obtain enough dyes...
