Unit of competency details

Unit descriptor 

This unit covers the understanding and knowledge required to use and apply knowledge of the physical and chemical properties of textiles in processing applications.

Application of the Unit 

The application of this unit is to apply the knowledge and understanding of the physical and chemical properties of textiles and associated materials to the design, treatment and processing of textile materials. This includes the resultant effects on and behaviours of materials when subjected to various treatments including washing, drying and curing, dying, printing, finishing using chemical and mechanical means, heating, stretching, cutting, spinning, weaving, stitching, water proofing, flame proofing, colouring, printing, etc.

Work may be conducted in small to large scale enterprises and may involve individual and team activities.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

• requirements prescribed by legislation, awards, agreements and conditions of employment
• standard operating procedures
• work instructions
• oral, written and visual communication
• quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output
• housekeeping
• tasks related to environmental protection, waste disposal, pollution control, and recycling

This unit requires the application of skills associated with initiative and enterprise and problem solving in identifying textile properties and determining effects from textile processing. Learning skills will be used to interpret and apply new information and communication skills will also be used to interpret specifications and technical information.
