STITCHED DOUBLE CLOTHS Introduction: 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 two layers may be only loosely connected together in which case each may be readily identified as a different entity or they may be so intricately stitched or tied together that they appear to form a complex single structure. The purpose of the construction may be entirely utilitarian, such as the improvement of the thermal insulation value of a fabric in which a fine, smart face appearance is necessary; or it may be aesthetic in intention for which purpose the existence of two series of threads in each direction improves the capacity for producing intricate effects dependent upon either colour, or structural changes. Double cloth produced by back to the face stitching system: In order to prevent confusion the different stages in working out a double cloth design should be represented by different kinds of marks, as shown in the following figures, which illustrates, step by step, the construction of a 5/3 and 4/4 twill structure in which the ends and picks are arranged 1 face, 1 back. A and B represent the face and the back weave respectively. At C an area equal to one repeat of the double weave is marked out with the order of arrangement of the face ends and picks and the back ends and picks indicated clearly at the margins. C shows the first stage of actual double cloth construction which may be defined as: Insert the face weave on the face ends and face picks only, according to the original design. The second stage is similar except that it refers to the back weave: Insert the back weave on the back ends and picks only, according to the original design. D shows the marks for the separating lifts which ensure that each series of yarns weaves only with its own kind and this may be stated as: Lift all face ends on back picks. Similarly, to complete the sequence, all back ends must be left down on all face picks which means an absence of marks, i.e. all back ends down on face picks. These are called mutual points. D also represents a stage in which two separate fabrics are produced one above the other. As there is no particular reason for producing two disconnected cloths in this manner, it will be realized that this stage is the intermediate point in the construction reached prior to the insertion of stitches or ties to bind the two cloths together. Before the stitch marks are inserted it must be decided which method of stitching is to be used and how frequently the cloths are to be stitched. Assuming that it is required to stitch by lifting the back ends on the face picks and that each back end is to stitch once in the repeat, the correct positions of the ties are shown by the crosses at figure D. The following figure D represent the final weave plan. End uses: Double cloths are used as different types of decorative cloth such as — sofa cover, furnishing cloth, curtain fabric, bed cover, pillow cover, and other home textile, etc. It is also used for the production of winter garments, quilts, belts, different types of industrial fabrics etc.
