What is challis? Challis is a lightweight woven fabric that was originally made by blending silk and wool, but there were also cases where a single fabric such as silk, cotton, or wool was used in creating it. Rayon, which is known to be a synthetic fiber, is now the most commonly used material in making challis because it is easier to obtain and more durable than the others.

What is Challis - Origin?
The origin of the word Challis is actually from the Anglo-Indian word “shallee” which means ‘soft’. According to history, Challis was first produced in Norwich, England during the early 1830s.
This type of fabric has been specifically designed to be soft and thin, much like the Norwich crepe, but rather than having a glossy texture, the Challis fabric has a matte texture and has been known to be more pliable. The traditional design for Challis comes with a paisley and floral patterns.
What is Challis Used For?
Challis was once extremely popular and has been casually used as a fabric for making dirndls, shawls, bed jackets, and even babushkas.

Due to the high popularity of challis, most fashion designers would use this fabric in making their clothing line. These ranges can be from loose-fitting tops to dresses, to skirts and even pants.

What is Challis – Stretching Property?
Since challis is a type of woven fabric, it won’t be as stretchy as other clothes, so it won’t be a good match if you are planning to use this for tight-fitting clothes. Any type of clothes that won’t be using a button or zipper will usually be a bad match for this type of fabric.
What is Challis – Is it good for the environment?
Since Challis is typically made by using natural and organic materials, it is deemed to be environmentally friendly. Depending on the type of material that was used to making the challis, it should degrade in about one to five years. There are some instances though in which non-organic cotton is used in making challis. Usually, non-organic cotton is treated with harmful chemicals and pesticides which are quite dangerous for the environment.

If silk was used in the making of this fabric, then it is not considered vegan. Silkworms would have been used and killed for obtaining the silk. To harvest silk from the silkworms, silk producers would usually boil the silkworms while inside their cocoons, killing the worms in the process. Just like most animals, silkworms also feel pain.
Using wool in making challis isn’t also animal-friendly because there are times that wool harvesters would hurt the woolen animals during the harvesting process. During the harvesting of their wools, the animals would sometimes get cuts or scratches in their skin, tails, ears, teats, and some other parts of the body.
The only time that this type of fabric will be considered animal-friendly or vegan is if it was made using only cotton.
