LETS START WITH MYJOURNEY....

Objectives

There are two objectives in producing double cloths

(a) To improve the thermal resistance value of the fabric.

(b) To give a good appearance and feel.

What is Double Cloth

Double cloths are those fabrics which consist of two layers of threads that are woven one above the other and stitched together.

Characteristic

These fabrics consists of a minimum of two series of warp

threads, and two series of weft threads, face and back.

The upper layer is found by interlacing the face warp

threads with the face weft threads, and lower layer by

interlacing the back warp threads with back weft threads.

They are also known as two ply fabrics.

Classification of double cloth

Double cloths are classified into the following categories…

• Self thread stitching.

• Center thread stitching.

• Double cloths Stitched by threads interchange.

• Double cloths Stitched by Cloth inter-change.

• Alternate single and double ply cloths

Self stitched double cloth

these fabrics contain only two series of threads in

both directions.

one series of warp and weft interlace to form the

face fabric and the other series of warp and weft

interlace to form the back fabric.
