Ingrain and wilton rugs

Ingrain

A flat-woven fabric made of two or three layers of cloth which interchange to form a pattern. Ingrain is not made at all today.

Wilton
A cutpile carpet woven on a Jacquard loom. This loom has anywhere from two to six boxes (or "frames") containing spools of varicolored yarn all feeding simultaneously into the fabric. The color which is required to make the design is pulled up to the surface, the selection being governed by a series of pierced cards which work somewhat on the principle of a player piano roll.
