Superwash wool (or super wash wool) is wool that has been treated to avoid some of the problems with caring for wool garments. This relatively new process, called "bio-polishing", was developed by the USDA's Agricultural Research Service.
Have you ever pulled a sweater out of the wash to find it many sizes too small, and maybe several times too thick? This is the result of a process called fulling (sometimes erroneously called felting). It is generally caused by a combination of agitation, heat, and (possibly harsh) detergent. Fulling can also occur when cooler water is introduced suddenly, such as hot wash water followed by warm or cool rinse water, as many automatic washing machines do. The reason hand washing is traditionally recommended for non-superwash wool is to avoid these temperature changes and agitation. Fulling can be done on purpose to create a stronger, thicker fabric that resembles actual wool felt; it has become a popular craft in its own right. Felting is a different process entirely.
Superwash wool, thanks to the bio-polishing process, is machine-washable. At the same time, the process removes some of the damaged tips of the wool (which can cause itching) and makes the wool smoother and softer in general.

Yes you can wash a wool jacket or any wool clothing. You have to hand wash it ( I do it in the sink ) and then let it air dry on a flat surface ( dont hang it the fibers will stretch )
You should wash in cold water and use low spin on your washer.
You can wash worsted wool pants by hand. Washing them in the washing machine can cause them to become damaged or misshapen.
Yup.
cold
Yes, you can use vinegar in the final rinse of a wool wash. It will not damage the fibers if you don't wash it out, it actually fluffs them up.
It is advisable to hand-wash pure wool, just to be absolutely safe. However, many modern washing machines have a "wool" cycle which is gentle enough to handle pure wool. Place the garment in a mesh washing bag (usually found in the laundry section of a supermarket) and use Wool Wash. It should be fine.
you wash it
Yes you can wash pashmina. You just need to first know what pashmina is made of. If it is pure pashmina wool then you should wash it using various wool wash products available in the market. Just take care of following things: Don't wring pashmina while washing Dry flat Don't rub too hard while washing, just gentle wash with wool wash should be fine.
If you want to wash your wool coat at home you should think about purchasing an at-home dry cleaning kit such as Dryel then follow the instructions on the package.
