Silk, being a natural product, should have an ivory hue to it and be slightly iridescent. Many manufacturers bleach their silk to enhance its look as well as remove some of the order of the residual serecin. However, although bleaching makes the silk look nicer appearance-wise, the nice looks will be short-lived as bleach-induced fiber damage will soon take its toll on the fabric as it becomes brittle and easy to break. Good silk filled comforters such as ours should always have a small zip opening on the shell of the comforter, allowing easy inspection of the silk filling.
