Fabric and Apparel

The One Thing

Fabric and apparel decisions must be based on the relationship between fibre and fabric properties, design requirements, production methods, care needs, and sustainability. Effective clothing therefore combines function, comfort, appearance, durability, appropriate maintenance, and responsible resource use.

Reactions, Processes and Experiments

Key Terms

• Fibre: A thin, flexible strand used as the basic raw material for making yarn and fabric.
• Natural fibre: A fibre obtained from plants or animals, such as cotton, linen, wool, and silk.
• Man-made fibre: A fibre produced through chemical or technological processes, such as rayon, nylon, polyester, and acrylic.
• Yarn: A continuous strand made by twisting or combining fibres for use in weaving, knitting, or other fabric construction.
• Spinning: The process of drawing out and twisting fibres to form yarn.
• Weaving: The interlacing of two sets of yarns, called warp and weft, at right angles to produce fabric.
• Warp: Yarns placed lengthwise on a loom during weaving.
• Weft: Yarns passed across the width of the fabric during weaving.
• Knitting: The construction of fabric by forming loops of yarn that are linked together.
• Non-woven fabric: Fabric made by bonding, felting, or pressing fibres together without weaving or knitting.
• Fabric finish: A treatment applied to improve a fabric's appearance, performance, texture, durability, or care properties.
• Apparel: Clothing and accessories designed to cover and protect the body or enhance appearance.
• Elements of design: Visual components used in clothing design, including line, shape, colour, texture, and space.
• Principles of design: Guidelines for arranging design elements, including balance, proportion, rhythm, emphasis, harmony, and unity.
• Balance: The visual distribution of weight in a design; it may be symmetrical, asymmetrical, or radial.
• Proportion: The relationship between the sizes of different parts of a garment and between the garment and the wearer.
• Rhythm: The repeated use of lines, colours, shapes, or details to create visual movement.
• Emphasis: The creation of a point of visual importance that attracts attention.
• Harmony: The pleasing relationship among the colours, textures, shapes, and details of a design.
• Pattern: A paper or digital template used to cut fabric pieces accurately for garment construction.
• Grain: The direction of yarns in a fabric; correct grain placement helps a garment hang and fit properly.
• Seam allowance: The extra fabric provided beyond the stitching line so garment pieces can be joined securely.
• Dart: A folded and stitched wedge of fabric used to shape a garment around the body's curves.
• Ease: The extra room added to a garment for comfort, movement, and wearing over other clothing.
• Bias: The diagonal direction of fabric, approximately 45 degrees to the warp and weft, which provides greater flexibility.
• Garment production: The planned sequence of activities through which fabric is converted into a finished garment.
• Quality control: The inspection and testing of materials, construction, measurements, appearance, and performance to maintain required standards.
• Care label: A label giving instructions for washing, bleaching, drying, ironing, and professional cleaning.
• Laundering: The cleaning of textile articles using suitable water, detergent, mechanical action, temperature, and drying methods.
• Stain: An unwanted mark or discolouration on a textile that should be treated according to its nature and the fibre.
• Sustainable apparel: Clothing produced, used, maintained, and discarded in ways that reduce environmental and social harm.

Easily Confused

• Natural fibre and man-made fibre: Natural fibres come from plants or animals, whereas man-made fibres are produced through chemical or technological processes.
• Warp and weft: Warp yarns run lengthwise on the loom, whereas weft yarns pass across the width.
• Weaving and knitting: Weaving interlaces warp and weft at right angles, whereas knitting forms linked loops of yarn.
• Elements and principles of design: Elements are the visual components of a design, whereas principles govern how those components are arranged.
• Grain and bias: Grain follows the direction of the fabric yarns, whereas bias lies diagonally at approximately 45 degrees and provides greater flexibility.
• Seam allowance and finished measurement: Seam allowance is added beyond the stitching line and is not included in the finished measurement.
• Ease and seam allowance: Ease provides extra room for comfort and movement, whereas seam allowance provides fabric for joining garment pieces.
• Washing and bleaching: Washing removes soil through water, detergent, temperature, and mechanical action, whereas bleaching uses a chemical treatment that must be compatible with the fibre and dye.
• Heat-sensitive and heat-tolerant fibres: Heat-sensitive fibres require low ironing temperatures, whereas heat-tolerant fibres may require moderate or higher settings.
• Functional and aesthetic requirements: Functional requirements concern comfort, protection, fit, and durability, whereas aesthetic requirements concern colour, style, proportion, and attractiveness.

What Gets Asked

• Explain the usual sequence of apparel production. Marks depend on stating the specific order from design development through fabric and trim selection, measurement, pattern making, marker planning, spreading, cutting, bundling, sewing, pressing, finishing, inspection, and packing.
• Compare fibres or select a suitable fabric. The answer must connect fibre properties to use: cotton is comfortable and absorbent but may wrinkle and shrink; wool provides warmth and resilience but may felt or shrink; silk is lustrous and delicate; polyester is strong, wrinkle-resistant, and quick-drying; nylon is strong and elastic; acrylic resembles wool and is lightweight.
• Explain the effect of design elements and principles. Specific effects may be required, such as vertical lines suggesting height, horizontal lines suggesting width, and diagonal or curved lines adding movement or softness. Warm colours generally appear advancing and energetic, while cool colours generally appear receding and calming.
• Calculate or explain fabric requirements and garment fit. Use fabric required = garment length + required allowances, adding extra length where necessary for sleeves, matching, shrinkage, and pattern placement. Do not include seam allowance in the finished measurement.
• Describe stain removal or laundering. State the ordered stain-removal stages, treat stains promptly, and consider the fibre, fabric construction, colour, finish, soil, stain, and care label. Heat, time, and pressure may set stains permanently.
• Interpret care requirements and sustainability practices. Follow the care label before selecting washing, bleaching, drying, ironing, or professional cleaning methods; avoid overloading washing machines, unsuitable bleach, excessive sunlight, and excessive heat, and identify practices such as repair, reuse, donation, recycling, and resource conservation.
