Double cloths are fabrics in which there are at least two series of warp and weft threads, each of which is engaged primarily in producing its own layer of cloth, thus forming a separate face cloth and a separate back cloth.
The purpose of the construction may be:
a. To improve the thermal insulation value of a fabric in which a fine, smart face appearance is necessary.
b. To improve the aesthetics
Classification of Double cloths
1. Self stitched double cloths:
These fabrics contain only two series of threads in both directions.
The stitiching of the face cloth layer to the back layer is accompalished by occasionally dropping a face end under a back pick, or by lifting a back end over a face pick or by utilizing both the systems.
2. Centre stitched Double Cloth:
In these fabrics a third series of threads is introduced either in warp or in weft direction whose entire function is to stitch the two otherwise separate layers of cloth together.
3. Double cloth stitched by thread interchange
In this cloth sometimes one thread acts as face thread and sometime acts as back thread. For this in the fabric parts, face warp becomes interlacement back weft and in some portion back warp becomes interlacement of face weft.This process goes on continuously and stitching is performed in the point of interchange position of threads.
4. Double cloths stitched by cloth interchange.
In these complete cloth layers are made to change places as shown:
5. Alternate single ply and double ply construction.
