Chemical Lace (sometimes referred to as Schiffli Lace) is a form of machine-made lace. This method of lace-making is done by embroidering a pattern on a sacrificial fabric that has been chemically treated so as to disintegrate after the pattern has been created.
This embroidery is typically done on a multi-head or multi-needle Schiffli machine or loom that has a very large, continuous and overlapping embroidery field. The lace pattern is designed such that the embroidery thread creates an interlocking series of threads that will, in essence, become a "stand alone" piece of lace.
After the embroidery is completed the embroidered fabric is immersed in a solution that will not harm the embroidery thread but completely dissolves the sacrificial fabric leaving just the lace.
Utilizing these large machines and this technique a single piece of lace could be, using today`s state-of-the-art machines, over 60" wide by 15yards long. In practice, this system is used to produce many smaller items with one setup.
