The differences between Silk and Satin. Silk is a naturally made animal protein fiber, whereas satin is an industrially produced fiber made from petroleum. Silk offers significantly good affinity to the skin due to similar chemical compositions. Each silk fiber is produced from 3-5 of these silk filaments which are subsequently spun together to produce silk fabric in an assortment of momme weights. Whereas the quality of stain(polyester) can vary from cheap to luxurious with the country of origin playing a large role in the quality of the product.
In short, silk is made from what is produced from silk worms and takes an incredibly large amount of animal proteins to make a small amount of silk fabric. This is why real silk pajamas can range from $100 to a few thousand while quality satin pajamas tend to start around $20.
