The ‘mm’ (millimetre) of silk fabric is a unit of measurement of the thickness and weight of silk, which represents the grams of silk per square metre. Specifically, 1 mm is equal to 4.3056 grams per square metre. This unit is usually used to indicate the quality and thickness of silk fabrics. The higher the value of mmm, the thicker the silk fibres are and the thicker and tighter the fabric will be.
When purchasing silk products, the value of the mm can be used as an important indicator of quality. For example, common silk garments are mainly made of 16mm, 19mm and 22mm, while loungewear may use 19mm, 22mm or even thicker fabrics. The mm value not only relates to the thickness of silk, but also affects its durability and feel. Generally speaking, silk fabrics with a high mm value are more durable, have a thicker hand, and have a better sheen.
However, a higher mm value is not better, as too high a mm value may result in a fabric that is too heavy and stiff for all purposes. For example, silk garments with a high mm value may be uncomfortable to wear in summer. Therefore, when choosing silk products, the appropriate mm value should be determined according to the actual needs and occasions of use.
