For silk dyeing Basic dyes are especially convenient, as they are well absorbed by the fiber and produce beautiful, bright colors, although they will fade in direct sunlight.

Before dyeing, contaminated silk products are washed in a warm, about 50-60 °C, solution of soap in water (50-60 g of soap per bucket of water).

Raw silk obtained by unwinding silk cocoons, as well as fabrics made from it, must be boiled in a soap solution before dyeing. For 1 kg of silk, take about 30 liters (2,5 buckets) of water and dissolve 250 g of good soap in it (Marseille soap is best). The silk is boiled in this solution for 1-2 hours until the threads are no longer sticky. Then the removed and slightly wrung out silk is transferred to a fresh soap solution, but weaker, and boiled for another 1 hour. After cooking, the silk is rinsed well and dried.

Hard, rustling silk products require special processing, and therefore you should not attempt to dye them without experience. The dye bath is prepared as follows:

For 1 kg of silk, take 1 bucket of water, certainly soft, and add about half a bucket of silk soap, that is, the soap broth remaining after boiling raw silk. Then add acetic or tartaric acid until the litmus paper moistened with the resulting solution begins to slightly turn red.

By pouring the dye, previously dissolved in a small amount of water, into the resulting solution in parts and stirring well, dyeing is done, starting at 40 ° C and gradually heating to a boil. Dyeing takes from half an hour to an hour. The amount of dye depending on the color is taken per 1 kg of silk from 5 to 20 kg.

At the end of dyeing, the silk is washed, soaked in water with the addition of acetic acid (5-7 g per bucket) and dried without washing.

Examples of dyeing recipes for 1 kg of silk:

Yellow

Chrysoidin 10 g;
Acetic acid about 20 cm3;
Glauber's salt 100 g.

Brown color

Bismarck brown extra 20 g;
Glauber's salt 150 g;
Acetic acid 20 cm3,

Green

Malachite green 10 g;
Acetic acid 20 cm3;
Glauber's salt 100 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 ... >>

Lynx in the water 01.07.2000

The amphibious hovercraft service boat was created by the joint efforts of specialists from the Neptune Central Design Bureau and the Almaz shipbuilding company (St. Petersburg). Thanks to ingenious design solutions, this boat can be operated in the most adverse conditions.

At a speed of about 60 km / h, it moves through shallow water and swamps, through snow and over ice (including broken ice). along hummocks and along rivers during ice drift and freeze-up, along water areas overgrown with algae and reeds. Its air cushion is 0,7 meters.

The vessel is even capable of climbing a long slope with a steepness of up to 5 degrees and overcome individual obstacles up to 0.5 meters high. . Even if both propulsion systems are damaged, the boat can be easily towed in hover mode. In the same mode, he is able to perfectly maneuver without a move, both on ice and on water.

Both the pilothouse for the crew (captain and mechanic) and the saloon for 14 passengers are comfortable, well-heated, equipped with ventilation and soundproofing.
