Monday Silks are very committed to high quality 6A long strand, 22 momme mulberry silk. If you're new to silk, it's highly likely you are asking 'what is high quality?' and 'what should I be looking when buying a silk pillowcase?'.
Below are some tips to help you understand how to pick high quality durable silk:
What is Mulberry Silk?
Firstly its important to understand Mulberry Silk is created by silkworms (Bombyx mori) who feed on especially grown mulberry tree leaves. The silk they spin their cocoons into is then used to produce silk products. Mulberry Silk is a natural fibre and regarded as the best silk you can buy for bedding and clothing.
Grades of Mulberry Silk
Silk is generally graded on an A, B, and C scale, with A referencing the highest quality. Grade A silk has long strands, contains almost no impurities and has a pearly white color with a healthy sheen to it. The number eg 3A, 5A, or 6A take the grading and makes it a step further, 6A being the highest. 3A are commonly used as filling in comforters and pillows, where as 6A is what Monday Silks use for their silk pillowcases and sheets.
What is 22-Momme?
Momme(mm) is used to measure density of silk fabrics and provide understanding of the quality in a silk fabric. Silk is an incredibly fine thread and therefore using thread counts would give an extremely high measure, compared to other materials such as cotton. Momme describes the silk’s weight and density. Higher momme means there is more strands of silk per 100 yards of fabric, therefore making the product heavier.
For silk bedding, you’ll want to get something with at least 19mm so it can withstand daily use and regular washing.
