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.
The Density of silk measured by momme.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 boast of a thread count of 750, while our 22Momme silk pillowcase has a thread count of 600+ and 19mm silk pillowcase, has a thread count of only 400. More threads = more durable and expensive.
Yes and no. It depends. Normally, 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. This can vary even between the same kind of silk. For example, lightweight Charmeuse is translucent when used in clothing, but 30-momme charmeuse is opaque. Therefore, it does not mean that you must always buy silk products with higher momme weight. For instance, it would be too heavy to put on 25mm silk sleepwear for the night, but 19mm silk sleepwear is not that durable, though. In a word, it is a question of making proper choices according to your own needs.
For bedding, the higher the weight in momme, the better the silk bedding is. Sheets between 19-25 momme are considered ideal. silk with momme weight lower than 19 are not suitable for the production of quality silk bedding linen. Beware of sellers trying to trick you into buying inferior quality sheets without declaring the momme weight. Always ask for this measurement before you buy.
Here at Orosesilk, we offer 3 different momme weight classes. Starting from the entry-level 19 momme, Orosesilk also offers intermediate 22 momme and luxury 25 momme weight classes for your choosing.
Thread count or threads per inch (TPI) is a measure of the coarseness or fineness of certain fabrics, most notably cotton. While it is not the definitive measurement of the quality of silk fabrics, it is good for reference when you purchase silk online. It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length (warp) and width (weft) threads. The thread count is the number of threads counted along two sides (up and across) of the square inch, added together.
