Ornamentation of Fabric

Chapter – 3

Self-Check Questions – 3

1. Define structural and decorative design.

Ans: (i) Structural design: In structural design, structure and design cannot be separated. The design is an integral part of the structure. If anything was taken away, it would not function. It is in its simplest form possible. 

(ii) Decorative design: This is the surface enrichment of structural design. Any lines, colour, or materials that have been applied to structural design for the purpose of adding a richer quality to it constitute its decorative design. Decorative design on the fabric can be produced by weaving, embroidery/ stitching, printing etc. the ornamentation of surface leads to increase the value of the product. 

2. Enlist the methods used in producing decorative design.

Ans: The methods used in producing decorative design are:

(i) Printing: Applying designs to fabric or other materials using various printing techniques.

(ii) Embroidery: Decorating fabric with needle and thread or yarn.

(iii) Painting: Applying paint to create unique, hand-painted designs.

(iv) Carving: Cutting into materials like wood, stone, or metal to create designs.

(v) Dyeing: Using color to create unique patterns and designs on fabric.

3. When and where do we use a dobby?

Ans: When the number of shafts to be controlled or the picks to a repeat of the design is beyond the range of tappet shedding, but is at the same time too small to be economically produced by a Jacquard, the dobby loom is used.

Uses: To produce stripes, checks, or designs of geometric character for dress materials.  

4. State the function of the following accessories of a draw boy loom: Overheald, Phoni, Ring.

Ans: The function of the following accessories of a draw boy loom are as follows: 

(i) Overheald: Overhalds are vertical cords connected with the sirash and warp threads. It is placed just at the back side of the ground heald. The ends of one dent is connected with one over heald to a single sirash. The overheald connections are done in accordance of the drafting of the design.

(ii) Pattern Former (Phoni): Phoni is a pattern forming unit which is produced in a wooden frame. In the phoni a pattern is prepared with required no of warp threads in the form of harness and required no of weft threads in ring form. The number of harness of the pattern former is depend upon the no of ends and drafting of the selected design. If the design is on straight draft the no of harness of the pattern former is equal to the no of ends of the design. On the other hand, if the design is on pointed draft the no of harness will be half plus one of the total no of ends of the design. The no of ring is depend on the no of picks (extra) of the design.

(iii) Ring: The ring is used to guide and manage the cords connected to the warp threads. It helps in keeping the cords organized and ensures smooth movement during the shedding process. It also helps the drawboy (assistant) identify and pull the correct set of threads for forming the pattern.

5. Which type of figuring is suitable by Draw boy loom?

Ans: The Drawboy loom is suitable for producing extra weft figuring designs, where additional weft threads are inserted selectively to create ornamental patterns over the ground weave. This type of figuring is commonly used in traditional handloom textiles such as chaddars, mekhela chadors, gamuchas, scarves, and sarees.

6. When and where do we use a Jacquard loom?

Ans: A Jacquard loom is used when highly intricate and large figured designs are required to be woven. It is a shedding device attached to the top of a handloom or power loom, designed to control a large number of individual warp threads independently. This allows the production of complex patterns without the limitations of traditional heald shafts.

The Jacquard mechanism was invented by Joseph Marie Jacquard in 1804. It operates using punched cards laced together in a continuous strip, with each card corresponding to one pick (weft insertion). This enables the loom to raise or lower specific warp threads to form detailed and decorative patterns.

Jacquard looms are widely used in the textile industry for producing decorative and elaborate fabrics, especially in home furnishings, upholstery, and fashion apparel. Common examples include brocade, damask, tapestry, brocatelle, and matelassé.

7. State any three comparisons between dobby and jacquard loom.

Ans: The three comparisons between dobby and jacquard loom are as follows:

(a) Design Complexity:

(i) Dobby Loom: Used for weaving small figured designs such as floral or geometric patterns, typically created by a combination of basic weaves. The designs are repetitive and simpler in structure.

(ii) Jacquard Loom: Can produce highly intricate and large designs using multiple weaves and colored yarns. The designs can be complex and varied, suitable for more elaborate decorative fabrics.

(b) Control of Warp Threads:

(i) Dobby Loom: Controls a limited number of warp threads, typically ranging from 6 to 48 heald shafts, with 16 to 20 shafts commonly used in industry.

(ii) Jacquard Loom: Controls individual warp threads separately and can handle a significantly larger number of warp threads, allowing for complex patterning on each thread, controlled by punched cards.

(c) Type of Fabrics Produced:

(i) Dobby Loom: Typically used for fabrics requiring smaller designs that are repeated throughout, such as chaddars, mekhela, gamuchas, and other traditional fabrics.

(ii) Jacquard Loom: Primarily used for producing elaborate and decorative fabrics, such as brocade, damask, tapestry, and matelassé, ideal for home furnishings and high-end apparel.

8. Write the uses of dobby loom.

Ans: The uses of dobby loom are: 

(i) Production of Small Figured Designs: Dobby looms are ideal for weaving small figured designs (floral, geometric, etc.), where the patterns are repeated throughout the fabric. These designs are created using a combination of two or more basic weaves.

(ii) Control of Limited Number of Heald Shafts: Dobby looms can control 6 to 48 individual threads (heald shafts), making them suitable for fabrics that do not require extremely intricate patterning like the Jacquard loom. In practical applications, it controls 24 to 36 heald shafts depending on the material (cotton, wool, or allied fibers).

(iii) Medium Complexity Designs: Dobby looms are used for fabrics that have a weave repeat of 6 to 24 ends. This makes them suitable for medium complexity designs, which involve moderate control of warp threads.

(iv) Weaving of Fabric with Multiple Picks per Repeat: While the number of picks per repeat can be high (several hundred), dobby looms are more effective for controlling a lower number of picks, making them best suited for designs that do not require extensive control over large numbers of picks.

(v) Cost-Effective Production of Repetitive Patterns: Dobby looms are used to create repetitive patterns on fabrics, making them ideal for applications where patterns need to be woven across the fabric at a reasonable cost and complexity.

9. Name any four CATD software used for developing woven design.

Ans: Textronics, GC Kala Brahma, Ned Graphics, Viable.

10. Enlist the main parts of the Piano Card Cutter.
