Carpet industry experts do not recommend washing hand-woven carpets at home due to the high risk this practice has for maintaining the health and longevity of the carpet, because this is usually done with common household materials that contain sodium bicarbonate, caustic soda. and the uncontrolled amount of hydrosulfite and cause the loss of the natural fat of wool fibers and make them too dry and brittle and cause color changes in the carpet, in addition, household washing tools are not suitable for this task, for example, if Washing the carpet requires the use of a brush. The hardest type of this brush that can be used to wash the carpet is made of horse tail and mane hair, while the brushes in the market that are for home use are made of plastic. Also, the space and environmental conditions are important for washing the carpet; For example, to dry a hand-woven carpet, it should not be exposed to the sun, although most people think that sunlight is useful for drying the carpet due to its disinfecting properties.
Now we will discuss the correct and principled way of washing handwoven carpets in an authorized and expert carpet cleaner, from the first step of collecting and transporting to the end of the washing operation, when the clean, ironed and covered carpets reach the owner of the carpet.
" جمعآوری و حمل و نقل "
Handwoven carpets must be separated from wet carpets, and handwoven carpets that are damp and wet are prioritized for transportation to the factory, and carpets must be protected from weather and environmental conditions such as snow, rain, and storms during their journey to the factory. because humidity causes color mixing in most handwoven carpets.

After the dust removal operation and damage detection (rotting, tearing, staining), it is time to wash the carpet, which is the most important and sensitive part of the work, because there are many factors involved that can be harmful to the handwoven carpet and must be carefully examined. to be placed, we mention a few of them; First of all, the amount of coloration of the carpet exposed to water should be tested and tested so that the necessary measures are taken. And shower with low temperature.
Alkaline and acidic materials should not be used in washing, especially materials that contain disodium carbonate, caustic soda, or a high amount of hydrosulfate, so the washing output water must be controlled during washing, color control visually and PH control using a litmus lamp. It should be done and if the effluent is not neutral, water and acid solution with suitable concentration should be used.
Sharia and Islamic rinsing should be done uniformly with appropriate water pressure so that when hanging the carpet, water collects in its lower part. Do not let yellowness and subsequent decay occur in this area.
At the end of the washing operation, the carpets are spread on a surface covered with coarse sand for 1-2 hours, which is called the period of carpet rest or recovery, so that they are prepared for water removal and drying.

At this stage, the remaining water on the surface of the carpet is separated and then the moisture of its fibers is removed, so it should be noted that during the washing operation, the amount of intertextured water in the fibers also increases (especially if it is wool) and should not decrease in the short term because It will cause its brittleness, so at this stage the temperature of the carpet should not exceed 40 degrees Celsius, and the carpet should not be exposed to direct sunlight because this will change the color of the carpet and the water droplets on the surface of the carpet will act like a lens, which will cause Sunlight is concentrated and burns the entire surface of the carpet in the micron dimensions of the fibers, which reduces the life of the carpet and damages it in subsequent washings.
In authorized carpet cleaners and experts in handwoven carpet washing, this step is performed using standard equipment and tools for drying and moving carpets so that during the washing and drying stages, the carpet is never exposed to direct sunlight and its temperature is constantly controlled. to be Also, in order to create uniformity on the surface of the carpet, a polishing machine is used with a low cut and it is ironed at the end, which is specific to first-class carpet cleaning factories.
