3003

COURSE OBJECTIVES:

• Understand the construction and classification woven fabrics.
• Understand the concept of design elements and features of basic weaves
• Construct the different kinds of basic weave structures
• Develop toweling, fancy weaves and color and weave effect

UNIT I	INTRODUCTION TO TEXTILE DESIGNING	9

Classification of textile fabrics; classification of woven fabrics - simple, compound and complex; fundamental aspects of woven fabrics-count of graph paper, Methods of representing design on graph paper; Principle of Design, draft, denting, lifting & tie-up plans. Types of draft - straight draft, skipped draft, pointed draft, herring bone draft, mixed draft etc. Plain weave - ornamentation of plain weaves; study of derivative structures of plain weave – regular and irregular warp rib, weft rib, hopsack and basket weaves. Catch-cord technique; design, draft, denting, peg/tie-up plan and thread interlacing diagram of above weaves

UNIT II	TWILL WEAVES AND ITS DERIVATIVES	9

Study of twill weaves up to 12 threads; classification of twills - warp faced twill, weft faced twill and equal faced twill, Left hand twill and Right hand twill; angle of inclination of twill diagonals- Steep twill and Flat twill; influence of the twist direction of yarn over prominence of twill lines; study of derivatives of twill weaves - wavy twill, herringbone, transposed twill, broken twill, elongated twill, combined twill, figured twill– Drafts, lifting plan & tie up, treadling plan for the above designs

UNIT III	DIAMOND AND SATIN WEAVES	9

Diamond weave, twill dice check, diaper; regular and irregular sateen and satin up to 12 threads, satin dice check weaves; design, draft, denting, peg/tie-up plan and thread interlacing diagram of above weaves. Difference between diamond and diaper, satin and sateen.

UNIT IV	TOWELLING WEAVES	9

Study of honey comb weaves– ordinary honey comb, stitched honey comb and Brighton’s honey comb designs- cell formation; study of Huck-a-Back weave- Construction of Standard Huck- a - Back (10 X 10), Devon’s Huck– a– Back ; mock-leno and corkscrew weaves. Design, draft, and peg/tie-up plan and thread interlacing diagram of above weaves

UNIT V	FANCY AND COLOUR AND WEAVE EFFECTS	9

Crepe weaves – construction upon sateen base, by combination of floating weaves with plain thread, by reversing and by insertion of one weave over another. Combination of weaves – twill and plain, mock-leno and plain, honey comb and plain, stripe and check effect by these combinations; Introduction to colour and weave effects- continuous line effect, hounds tooth patterns, bird’s eye and spot effects, hairline stripes, step patterns and all over effects. Distorted thread effects – salient feature, warp and weft distortion.

TOTAL: 45 PERIODS

COURSE OUTCOMES:: Upon completion of the course, students will be able to

Upon the completion of this course the student will be able to CO1: Identify and construct plain weave and its derivatives. CO2: Create different twill weaves structures and its derivatives. CO3: Draw the designs of Diamond and satin weaves. CO4: Develop woven fabric designs suitable for towels. CO5: Create fabric designs using different color and weave effects.
