1, generally one side of the wool quilt will have a zipper. After opening it, first, look at the color of wool. Not as white as possible. The wool of an authentic Australian 9-month-old lamb is gray. If it is too white, it means that the quality of wool is not very good, and there are many procedures for decontamination and impurity removal, which may damage the surface protein.
2, it depends on the fiber thickness. According to the certification of the International Wool Bureau, wool with a length of 2~3 inches and a fineness of 28~32 microns is the most suitable wool quilt, and it is not good to be too fine or too thick.
3, look at the package fabric. The outer cloth must not have a coating similar to the light-proof curtain, so it is very likely that the oil rate and impurity removal of the inner wool are not enough, and the outer layer is used to prevent extravasation.
4. smell the wool quilt. The carbonized, washed and combed wool will not have any peculiar smell, including the smell of mutton.
5. Feel the softness of the fabric. If the quilt is hard or brittle, it may be that the fabric has a sponge or coating, so the comfort of the quilt is poor and formaldehyde may exceed the standard.
6. As long as it claims to be 100% pure wool, it must be the wool of a live sheep.
7, it is best to be the wool of the lamb. It is said that this kind of hair is the softest and warmest.
According to the above points, I believe you can definitely choose a satisfactory wool quilt.
