Silk crepeline is a thin and transparent silk fabric having a plain weave. It is often used in Europe and America for textile conservation, especially for fragile objects. China in recent years has witnessed the introduction of and the ever increasingly wide usage of crepeline. But the product has never been locally made in China, so the China National Silk Museum has cooperated with Zhejiang Science and Technology University to research, to develop, and to produce this fabric. This paper introduces the characteristics of the developed fabric and the ways to use it in the conservation of ancient Chinese textiles. This fabric usually covers the ancient textiles and is sewed to the objects with stitches. There are two ways of covering depending on the state of preservation of ancient textiles. One is to cover the whole object, and the other is to cover the damaged area only. And there are three methods to use the silk crepeline in layers. One is to sandwich the ancient fabric between an overlay of silk crepeline. The second is to use only one layer of silk crepeline on the top and to use a support fabric that is the similar to the ancient object. The third is to use more than one layer of crepeline in different colors as the support fabric in order to get a color close to that of the ancient textile.The use of crepeline is a very good textile conservation method.It is especially good for the treatment of objects that are too fragile to be stitched. One problem of this method is the loss of edge threads after the final cut.
