Construction and Development of Double Cloth with 2 Distinct Jacquard Patterns without any Design Impact

Construction of Jacquard Designs:

The construction of jacquard designs include the preparation of a card cutting plan on squared paper, which in most cases when an ordinary jacquard is used shows the complete working of every thread in the repeat. As opposed to the above system of detailed designing there exist forms of condensed design preparation where only the main motif is shown in block outline, and where the detailed weaves for each part of the motif.

In general the detailed form of designing in the point-paper may be constructed from a basic artwork or original sketch, of which the woven sample is required to be reproduced.

Here assume that we involve an enlargement of the design and the degree of increase in size varying is in the same pitch of design paper.

It is a good method to decide upon a number of ends for a repeat which is a multiple of several smaller numbers, and to use this number for cloths which vary slightly in fineness.

The formula is:

Hooks in jacquard x sett of     warp in reed

                                            sett of harness

Gives the number of ends upon which the design should be made in order that the warp will be perfectly straight between the harness and the reed.

Development of Figures:

After a figure has been correctly painted the next process is usually to insert suitable weaves upon it. The designs should be selected with the following objects in view: (1) To produce a good compact fabric without any distraction the allover designs in which the threads arc interwoven to such a degree that they are not liable to slip or fray when the fabric is subjected to strain and friction (2) To develop the figure in such a manner that the form is shown two distinct designs for aesthetic variation.

Prevention of Long Floats:

In some designs given in the form breaks up the mass of the figure to such a degree that binding weave is required to be inserted either for stopping the floats of yarn or for developing the effect.
