Design for Fabric and Apparel
Chapter – 8
| PART – ⅠⅠ HUMAN ECOLOGY AND FAMILY SCIENCES |
| Unit – IV Fabric and Apparel |
Review Questions:
1. What do you understand by the term ‘design’?
Ans: Design implies intention, meaning, and purpose; The planning and patterning of any act toward a desired, foreseeable end constitutes the design process; Design is creative problem solving.
2. What are the factors that affect the texture of a fabric during its manufacture?
Ans: The factors that affect the texture of a fabric during its manufacture are mentioned below:
(i) Fibre content: fibre type (natural or man-made), its length and fineness and its surface characteristics.
(ii) Yarn processing and yarn type: method of processing, twist inserted during processing, fineness of the yarn and yarn type (simple, complex, novelty or textured).
(iii) Fabric construction technique: weaving (type of weave and its compactness), knitting, felting, braiding, lace-making etc.
(iv) Fabric finishes: stiffening (starching, sizing or gumming), ironing, calendaring and tentering, napping, fulling.
(v) Surface ornamentation: tufting, flock printing, embroidery, and stitched effects.
3. How does the application of colour during the different stages of fabric manufacture affect the design in fabric?
Ans: The application of color during the different stages of fabric manufacture plays a significant role in the final design and appearance of the fabric are mentioned below:
(i) Fiber Stage (Solution Dyeing):
(a) Effect on Design: Solution dyeing is done at the fiber stage before the yarn or fabric is formed. This allows for uniform and long-lasting colors that do not fade easily.
(b) Design Implications: Limited to solid colors or slight blending effects in the fabric. Ideal for creating consistent and durable designs.
(ii) Yarn Stage (Yarn Dyeing):
(a) Effect on Design: Yarns are dyed before weaving or knitting. This method provides vibrant, long-lasting colors.
(b) Design Implications: Allows for intricate patterns like stripes, checks, and plaids since colored threads can be woven into detailed designs.
(iii) Fabric Stage (Piece Dyeing):
(a) Effect on Design: The fabric is dyed as a whole after weaving or knitting. This provides flexibility in choosing colors after the fabric is created.
(b) Design Implications: Ideal for creating solid-colored fabrics. It is less effective for intricate, multicolored patterns but allows for large areas of uniform color.
(iv) Garment Stage (Garment Dyeing):
(a) Effect on Design: The fully constructed garment is dyed. This is often used for small production runs or to achieve specific color effects on completed items.
(b) Design Implications: Best for simple, solid colors with unique finishes like a washed or faded look. Not suitable for complex designs.
(v) Printing (Post-Fabric Stage):
(a) Effect on Design: Colors are applied in specific patterns on already dyed or undyed fabric.
(b) Design Implications: Allows for highly detailed and vibrant multicolor designs, such as florals, geometric shapes, and illustrations. Printing is crucial for achieving intricate and varied fabric designs.
4. What are the different types of lines and shapes? How do they create different effects and moods?
Ans: There are two basic types of line-the straight line and the curved line.
Straight Lines: The straight line is a rigid unbroken line. Straight lines create different effects depending on their direction. They can also express Mood.
(i) Vertical lines stress up and down movement, emphasise height and give the effect that is severe, dignified and reserved.
(ii) Horizontal lines stress side to side movement and create a illusion of width. Since they repeat the ground line, they give a stable and placid Effect.
(iii) Oblique or diagonal lines increase or decrease width and height depending on the degree and direction of angle. They can create an active, startling or dramatic effect.
Curved Lines: The curved line is one with any degree of roundness. The curved line can be a simple arc or a complicated free hand curve. The degree of roundness determines the curve. A slight degree of roundness is called a restrained curve; a great degree of roundness gives a circular curve. Certain objects are associated with these curves and named as such, for example, parabola, scroll, meander, hairpin, whiplash, or serpentine, figure of 8, ogee, etc.
(i) Long and flowing curved lines appear most graceful and rhythmic.
(ii) Large rounded curves lend a dramatic touch and tend to exaggerate Size.
(iii) Tiny, puffy curves are youthful and gay.
Line expresses visual meaning; straight lines indicate force, strength and rigidity, whereas, curved lines appear soft and graceful when used in design. If straight lines are more dominant, the design effect is masculine. Curved lines give the impression of feminity and daintiness.
Shapes or Forms: These are made by connecting lines. Shapes can be two dimensional, as a drawing or a print on paper or fabric. They can be three dimensional as an object that can be viewed from three or more sides, like a human body or the garments on it. Since shapes are formed by connecting lines, the characteristics of the lines used will determine the characteristics of the shape. If only straight lines are used the shape will be different than if only curved lines are used. By using different types of lines in different combinations, numerous varieties of shapes can be created.
There are four basic groups of shapes:
(i) Natural shapes are those that copy nature or common shapes of man-made objects.
(ii) Stylised shapes are simplified or modified natural shapes. They may have some part distorted or exaggerated.
(iii) Geometric shapes are those that can be mathematically formed, or gives a similar impression. They can be formed by using rulers, compasses, or other measuring instruments.
(iv) Abstract shapes are free-form. They do not resemble any specific object but, may represent different things to different people because of personal association.
5. How do you achieve rhythm and harmony in dress?
Ans: Rhythm is repeating of lines, colours, other elements of design or details to create a pattern by which the eye can flow through the material or article/garment. Rhythm can be created by use of lines, shapes, colours and textures in such a way that it gives visual unity. It can be created by:
(i) Repetition of embroidery laces, buttons piping, colour, etc. at necklines, sleeves and hemlines.
(ii) Cordation by gradual increase or decrease in size of motifs, lines, buttons, colours and textures.
(iii) Radiation where eyes move in an organised way from a central point e.g., gathers in waist, yolk or cuffs, etc.
(iv) Parallelism where elements lie parallel to each other e.g., tucks in a yoke or knife pleats in a skirt. Bands of colour also create a rhythm effect in a dress.
Harmony: Harmony or unity is created when all elements of design come together to give a pleasing harmonious effect. It is a critical factor in producing marketable (publicly acceptable) designs. Harmony by shape is created when all areas of a garment reflect the same shape. The collar, cuff and hem are curved and it square pockets are given they would interrupt the continuity of the design. Harmony by texture can be created by using the right kind of texture for a dress when dress is in several pieces as in salwar kurta and dupatta. A silk kurta and salwar will show bad harmony by use of cotton dupatta.
