  • understand the factors which constitute suitability/ fitness for purpose, i.e. wearability, warmth, comfort, absorbency, durability, after care, safety, flammability, stain resistance, aesthetic qualities.

 

Finishing Processes

Candidates should be taught to:

Dyeing and printing

  • have a knowledge and understanding of one basic commercial method and one hand method of dyeing and printing fabric.

Decoration and enhancement

  • select and know how to use a variety of appropriate surface decorative techniques in order to improve the aesthetic qualities of textiles, fabrics and products.

Finishes

  • have a working knowledge of finishes (to include stain resistance, water resistance, flame retardancy, crease resistance) applied to fabrics in order to improve their performance; evaluate the effects of these fabric finishes paying attention to use, comfort, safety, maintenance, manufacturing costs and retail price; 
  • have knowledge of at least one modern 'Smart' finish to fabrics (to include thermochromatic printing);
  • have knowledge of emerging technologies: nano materials and integrated electronics within textiles designs.

 

 

 

Components

Candidates should be taught to:

Manufactured Components 

  • select, use and evaluate the function, suitability and safety of manufactured components in design and make tasks; identify and have a working knowledge of components including fastenings (to include zips, buttons and Velcro), threads, trimmings, interfacing, motifs, labels and electronic components; be aware of the technological advancements in component design.

Design and market influences

Design and market influences

 Candidates should be taught how to analyse textile products and processes. They should consider how design and technology affects the manufacturer, user and environment, and the importance of health and safety issues. They should be aware of new developments in technology and current social issues that may influence product design.

Product analysis

Candidates should be taught to:

Product Design

  • understand the influence of trend forecasts when designing textiles products; 
  • analyse past and present textile designs and products in order to evaluate shape, style, aesthetics, choice of materials and components, construction techniques, decorative techniques, fitness for purpose, marketability; and use the findings of this research to generate new and original design ideas.

Evaluation Techniques 

  • check of design proposals against design criteria; 
  • use disassembly to make critical judgements about the design, manufacture and performance of existing products; 
  • list design criteria that influence textile product design and use this to test and evaluate the final design proposal; 
  • understand the purpose and value of a design specification to guide design thinking; 
  • quality assurance through testing and evaluation of quality and fitness for purpose; 
  • use ongoing evaluation to make judgements and to suggest improvements during design development and making activities;
  • consider other peoples' views when selecting and refining product designs, to include user trials.

Evaluation of quality of own product compared with market alternatives 

  • compare design proposal to a similar commercial product in order to review and modify design;
  • evaluate the appeal, quality and fitness for purpose of the design proposal against consumer expectations.

Social, Cultural, Moral, Health and Safety and Environment Issues

Candidates should be taught to:

Social and cultural influences on the consumer market 

  • understand the role of the designer and consider the impact of design proposals on society; 
  • identify developments in technologies, social and cultural ideas, fashion trends and economic factors that influence consumer choice and product design.

Consumer choice and ethical issues 

  • understand the influence of ethical trading and the consumers' role in social and environmentally sustainable design.

Moral and environmental issues

  • understand the moral and environmental issues associated with textiles production;
  • understand what is meant by the recycling of textiles, waste reduction, organic and Fair Trade cotton, bio fibres, biodegradable fibres/fabrics.

Environmental effects: the disposal of chemicals used to manufacture products; the need to dispose of waste in a safe and environmentally friendly way

Candidates should be taught to:

Health and Safety issues 

  • understand that the health and safety of both consumers and the work force is important.

As designers and consumers:

  • select the appropriate materials and components;
  • consider safety in terms of function;
  • be aware of consumer rights and safety warnings on textile products.

As manufacturers: 

be aware of and understand Risk Assessments in relation to:

  • the correct and safe use of tools and equipment;
  • the correct and safe usage of materials, chemicals, solvents, flammable and toxic substances used in textile manufacture; 
  • the need for correct protective clothing and safe working practices.

Processes and manufacture

Processes and manufacture

Candidates should be aware of, and use appropriate, manufacturing processes and techniques including CAD and CAM. They should be aware of industrial and commercial practice and know about the processes involved in the commercial manufacture of textile products.

Candidates should be taught to:

Techniques And Processes
