Dyeing fabric or yarn produced in a clean enameled cauldron or saucepan. Copper utensils can cause a dirty cast in the coloring. The bath is made up of hot water (1 liters of water per 20 kg of yarn or fabric), in which soda ash is dissolved. Glauber's salt or table salt replacing it is also added here. The dye solution is prepared separately by dissolving it in a small amount of hot water.

The amount of soda, salt and dye depends on the color, namely:

For dark shades it is necessary to take from 20 to 50 g of dye, for black ones 60-70 g per 1 kg of material to be dyed, soda 30 g and Glauber's or common salt 200-300 g.

For medium shades (red, light blue, gray, etc.) - dye 10-20 g per 1 kg of fabric, soda 20 g and Glauber's salt 100 g.

For light shades (pink, blue, cream, etc.) - dye 5 g, soda 10 g, Glauber's salt 30-50 g and soap 10-20 g.

The latter is added along with soda. To achieve uniform dyeing, the dye should not be absorbed by the fiber too quickly, and therefore its solution is added to the solution of soda and Glauber's salt not all at once, but in two or three steps. Bleaching of linseed oil Before immersing the fabric or yarn, the bath with a given dye is well stirred, and when pouring the second half of the dye, the material is removed from the bath and immersed again only after a new portion of the dye is evenly distributed throughout the bath. If these precautions are not followed, the dye will stain the fabric. For the same purpose, during dyeing, the material is turned over more often at the beginning, less often at the end of dyeing.

A bath for dyeing is prepared by dissolving a weighed amount of soda in hot water, then Glauber's salt or table salt is added by direct pouring into the boiler, after which the first half of the dye solution is added. The fabric or yarn, previously moistened and wrung out, is immersed in a bath and kept at a low boil for about half an hour. Then add the rest of the dye and continue dyeing for about an hour or more, until the material takes on the desired color. It should be noted that after drying, the color is lighter than in its raw form. The dyed material is rinsed in cold water, then in warm soapy water and again in cold water. The pressed material is then hung out to dry.

For example, here are a few recipes for 1 kg of fabric or yarn:

Red

Aniline of strong red F 20 g;
Soda ash 20 g;
Glauber's salt 100 g.

Blue

Aniline pure blue FF 5 g;
Soda ash 10 g;
Soap 10 g;
Glauber's salt 50 g.

Black color

Aniline dark black E extra 60 g;
Soda ash 30 g;
Salt 260 g.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Hydrogen fuel from sea water 30.03.2019

Hydrogen fuel is becoming increasingly important in today's world. So scientists at Stanford University and Peking University have figured out how to turn seawater into hydrogen fuel using a chemical reaction from a high school course.

So, according to the researchers, if you run an electric current through water, it splits into oxygen and hydrogen - the latter can be used as a reliable source of fuel with zero emissions.

Experts have developed a new metal coating for the electrodes used in the experiment, which would allow them to withstand the chemical reaction that occurs in salt water. Since an electric charge is needed to separate water into hydrogen and oxygen, scientists tried to make their device as environmentally friendly as possible by installing solar panels on it.

Chemist Hongjie Dai said the system could be installed on submarines or diving gear.

Hydrogen fuel cells can power a submarine or diver's equipment, while oxygen produced by a chemical reaction can be supplied to a person, replenishing his reserves so that he can breathe. At the same time, experts note that any practical application is not possible soon, since the study only demonstrates that such a technology, in principle, can work.

Until now, the processes have been based on purified fresh water, which is quite expensive. Producing hydrogen fuel from fresh water sources could create problems for those who have a life-saving need for the liquid, scientists say. This is especially true as climate change could soon exacerbate drought around the world.
