The OEKO-TEX® standards 100 is developed and managed by the International OEKO-TEX® Association, a group of 16 textile research and test institutes in Europe and Japan, with representative agencies and contact offices in over 60 countries worldwide.

Products that pass the test in this system are allowed to carry a certification label that guarantees that the product does not contain harmful substances at levels that can be dangerous to the human body. No matter beddings or sleepwears， most of Lilysilk's products own the OEKO certification and are safe and healthy for your skin.

1. Flames:

Genuine quality silk: Burning genuine silk produces a smell very similar to that of burning human hair. The flame is close to invisible when burning the edge of the natural silk fabric. Very soon after the flame source is taken away from the fabric, the silk will self-extinguish.

Fake silk: Most fake silk is, in fact, petroleum-based polyester products. When burned, these materials tend to combust rapidly in intense flames and smell burning plastic.

2. Ashes

Genuine silk: The ash from burning is black, crispy, and turns to powder quickly when ground.

Fake silk: The ash of artificial silk tend to be sticky, twisted, and difficult to break apart.

Mommes (mm) is a unit traditionally used to measure the quality of silk fabrics. One momme = 4.340 grams per square meter; 8 mommes is approximately 1 ounce per square yard or 35 grams per square meter. Momme is used to measure the density of silk.

The density of the threads in the 25 momme variety of silk is also significantly higher than that of the 22 momme or 19 momme. Our 25 momme silk pillowcase boasts a thread count of 750, while our 22Momme silk pillowcase has a thread count of 600+ and 19mm silk pillowcase, with a thread count of only 400. More threads = more durable and expensive. Usually, the higher the momme weight, the more durable the weave, the more luxurious the fabric is, the more suitable it is for heavy-duty use, and the longer the shelf-life. Generally, all silks can be washed and the heavier ones can be washed repeatedly. The heavier the silk, the more opaque it becomes.

1. Mulberry silk

Mulberry silk is the long silk fiber produced by matured and domesticated silkworms when they secrete liquid silk, also known as “natural silk fiber”. It is the earliest animal fiber used by human beings and the most genuine silk fiber for all kinds of silk clothes, which is lightweight, soft, and absorbent of moisture. In addition, mulberry silk contains over 18 amino acids and protein fibers which is healthy for human skin and hair. For example, the hygroscopicity of the mulberry silk comforter is 1.5 times higher than that of cotton comforters. Besides, mulberry silk is pretty hypoallergenic, and as a consequence, many dermatologists recommend silk bedding and apparel for aged and sick people. Compared to other silk fibers, mulberry silk is more luxurious and breathable. It may not be that durable, but who’s going to use the same bedding for life?

2. Tussah Silk

Tussah silk, also known as ‘shantung,’ is a type of wild silk produced by tussah silkworms that feed on oak and juniper leaves. The silk has a feel and quality different from the mulberry silk. As the worm is not grown in a controlled environment, the moth hatches from the cocoon and interrupts the filament length, resulting in short and coarse fibers instead of long and lustrous ones. Usually, it is widespread in China and other Asian countries like India, difficult to dye, and most often available in its natural color, a creamy tan. It is also lightweight and airy, as well as dressy, giving excellent comfort to the wearer. Moreover, it does not wrinkle easily, which makes it suitable for traveling.
