Select dyes and develop dye specification and recipe for production

Assessment tool

Version 1.0
Issue Date: May 2024


This unit of competency covers the skills and knowledge associated with selecting, developing and testing dyes, chemicals and auxiliaries, and developing a dye specification and recipe for the production of textiles.

This unit of competency applies to textile material and products for which product specifications are developed in the textile sector, including fibres, fabrics, yarns and finished products.

Judgement may be required in planning and selecting appropriate processes or procedures for self and others.

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

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

developing, checking and filing dye specification and recipe in accordance with workplace procedures and industry and quality standards

preparing reports and documentation

monitoring dye specification and recipe to ensure continuity and repeatability of colour and test results

complying with environmental requirements and workplace procedures at all stages of the process.

Evidence must be provided that demonstrates knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

relevant Australian Standards

fibres, yarns and end products and their properties

dye stuffs and classes

chemistry of dyes and relevance to processing and fastness properties

dyeing processes and dyeing machinery

relation between dye machinery and selection of dye stuffs and classes

tests applicable to the dyeing of textiles

Assessors must:

satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator

have vocational competency in selecting dyes and developing dye specifications and recipe, at least to the level being assessed, with relevant industry knowledge and experience.

Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
