HSC Textiles and Design cheat sheet

Design process stages: identify need or problem, research, design brief and specification, idea generation, development, prototyping, evaluation, production.

Elements of design: line, shape, form, colour, texture, space, value; principles: balance, rhythm, proportion, emphasis, unity, contrast.

A design brief states the problem, target market, constraints and purpose; a design specification lists measurable criteria (dimensions, cost, performance) used to evaluate the final product.

Colour schemes: monochromatic (one hue), analogous (adjacent hues), complementary (opposite hues), triadic (three evenly spaced hues); value is lightness/darkness, intensity is saturation.

Ergonomic and anthropometric data (body measurements, reach, movement) drive garment fit; functional design prioritises use, aesthetic design prioritises visual appeal.

Target market segmentation uses demographics (age, income, gender), psychographics (values, lifestyle) and geographics; user-centred design tests prototypes with end users.

Evaluation compares outcomes against the specification using criteria and evidence; iterative redesign follows feedback rather than ending at first prototype.

Fibre classification: natural (cotton, linen, wool, silk) versus manufactured (regenerated such as viscose, synthetic such as polyester, nylon, elastane).

Staple fibres are short and spun into yarn; filament fibres are continuous. Longer staple and finer fibre give smoother, stronger yarn.

Yarn properties: twist direction (S or Z), twist level, count (fineness); higher twist increases strength and firmness but reduces softness and loft.

Fabric structures: woven (plain, twill, satin), knitted (weft/weft-knit, warp-knit), nonwoven (bonded, felted); structure governs stretch, drape, stability and fraying.

Performance properties: absorbency, moisture regain, tenacity, abrasion resistance, elasticity, flammability, thermal insulation, colourfastness, pilling.

Cotton: absorbent, breathable, comfortable, low elasticity, wrinkles, weak when wet. Polyester: strong, quick-drying, low absorbency, thermoplastic, resists wrinkles, can pill.

Wool: hygroscopic, insulating, elastic, flame-resistant, felts with heat and agitation; silk: strong, lustrous, low elasticity, sensitive to sunlight.

Care and finish: mechanical finishes (calendering, brushing), chemical finishes (water repellent, flame retardant, easy-care); care labels reflect fibre and finish behaviour.

Performance testing includes abrasion (Martindale), strength (tensile, tear), colourfastness (wash, light, rub) and pilling (Pilling box), reported against standards.

Sectors: textile production (spinning, weaving, knitting, finishing), clothing manufacture, footwear, and allied industries (machinery, chemicals, retail, design services, education).

Industry structure ranges from large-scale manufacturers to small-to-medium enterprises (SMEs) and micro design businesses; many firms specialise in niche, high-value or technical products.

Supply chain stages: fibre and yarn supply, fabric production, design and product development, cut-make-trim (CMT), logistics, wholesale/retail, and end-of-life disposal or recycling.

Competitive pressures: low-cost overseas labour, globalisation, tariffs and trade agreements, exchange rates, and fast-changing consumer demand; local firms compete on quality, speed, innovation and sustainability.

Employment roles include designers, patternmakers, garment technicians, machinists, quality controllers, merchandisers, buyers and supply-chain managers.

Legislation and compliance: consumer law on product safety and labelling, mandatory care labelling, country-of-origin labelling, workplace health and safety, and environmental regulation of waste and chemicals.

Sustainability responses: ethical sourcing and supply-chain transparency, Australian cotton and Merino programs, recycled fibres, circular design, reduced waste through efficient cutting and zero-waste patternmaking.

Technology adoption: computer-aided design (CAD), computer-aided manufacturing (CAM), digital printing, automated cutting, and e-commerce reshaping production and retail.

The project comprises a designed and made textile item plus a supporting documented report; the item and report are assessed together.

A clear design brief and specification must be established first; every later decision and evaluation is judged against those stated criteria.

Documentation should show evidence of the design process: research, idea development, experimentation with techniques and materials, decisions with justification, and testing.

The report must include a materials and components list with reasons for each choice, linked to performance requirements of the item.

Technique selection needs justification: for example, why a particular seam, knit, print method or embellishment suits the function, aesthetics and target user.

Evidence of quality: samples, test results (e.g., wash or abrasion), photographs of stages, and records of modifications made during making.

Evaluation must be critical, referencing the specification, user feedback and the strengths and limitations of the finished item, plus suggested improvements.

Presentation and communication matter: logical structure, accurate terminology, labelled visuals and a coherent link between the written report and the made item.
