Hi, This is @mdyousufali, From Bangladesh
Bismillahir Rahmani Rahim Friends of the Steam world Greetings to all of you Salam Assalamu Alaikum wa Rahmatullah be well. By the infinite mercy of Almighty Allah, Allah Almighty has kept it very good. The topic that I will discuss or share today. Who and how to do the rubbing test. So we have to know that we must first know what is rubbing? . Running is how or how quickly a fabric's color will run out of it as a result of rape. Basically this is tried as if the garments we wear. These garments rub against our body and one garment rubs against another garment. As a result of this friction, what amount of paint is removed is basically what we call rubbing.

In fact, many of us do not know about this, so this Fastnest is a variant of Fastnest, which is Robi. So first let me discuss the first niski fast match is actually how or how much color can be removed from a fabric we call fastness. So let's discuss the first match fastnest basically four types of rubbing fastness two. Color Haasness. Perspiration first. and filling test. Out of all these, I will discuss the whole process of how to rub in front of you today and represent it through pictures.
This is the crop meter, we use this crop meter to test the rubbing fastness. The Tui Cook meter is a crop meter originally made in Germany. So here basically in the first condition to take two samples of the oven fabric. It is mainly provided by the mother and there are some standards to measure from that standard.
test specimen Or test paper

So first of all we will dabbing this sample in dry state and rubbing another sample in wet state. So basically we have cut the fabric in a certain shape for the rubbing test. Then we will stick the oven fabric to the brushing system or handle of the crock meter of the rubbing machine with a pin. Then there are some specific parameters of the machine, we will set those parameters according to the requirements of the ISO buyer. After that we will robin according to the requirement of 10 circles 15 circles or different circles outside.
So here's a screw and a date sample. We basically stick the HS paper in the Rabiul meter with the help of this school and then we start working.
finally test specimen are done , now we can ready for rubbing test report

So here's a clip of this click from that little sample of the machine brushing. By setting the machine parameters on it we will start rubbing. Then after the completion of the 10th day you can see one happening. The sample was prepared by soaking the other cup in water and then rabining it. Here I have added the same sample one by one, so many times multiple samples may need to be added according to external requirements.
Required Dead Weight for Rubbing Test

So finally many rubbings are done when the laboratory has a lot of juice. About 200 to 300 Ravans have to be done in about eight hour sector according to different requirements of different buyers. These Arabins of yours need to be maintained by one IS for each outside. So all in all we have done approximately 20000 Rabin from eight in the morning to six in the evening. So many times depending on the workload this rubbing may be done up to 300. We added these after wrapping and below are the agricultural resources we tested first miss. Among these can be station tests in alkaline medium in acid medium and one of them includes Saliva. Testing is done mainly here kits i.e. baby or garments for babies are sent to us for testing. So we're basically here with that baby's dress tear or half mouth saliva resistance. I test how much power is available. So that's it for today, then we close the work and go home. Everyone will be fine. Some other day we will discuss some other test in front of you, inshallah.
