Habutai Habutai Habutai or habotai (from the Japanese , literally "feather-two-layer") is one of the most basic plain weaves of silk fabric. While it was traditionally woven in Japan, most habutai is today woven in China. It is normally a lining silk but can also be used for T-shirts, lampshades, summer blouses or very light lingerie. It is quite easy to dye and can be found in many stores. Like other kinds of silks, habutai comes in a variety of weights/ thicknesses which is measured in mommes (abbreviated "mm"). A lightweight and sheer habutai silk might be 8 mommes ("8mm"); a
Waterproof fabric Standard laboratory testing protocols define the performance of these fabrics. Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. Breathability or Moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m/d), often abbreviated to just "g". In recent years some, but not all, sporting goods manufacturers have begun including this information on their product labels. Typical mid-range fabrics tend to have values of 5,000 mm of water resistance
