Description
This unit covers the skills and knowledge associated with selecting, developing and testing dyes, chemical and auxiliaries and developing a dye specification and recipe for the production of textiles.
Notes
Elements and Performance Criteria
1 Identify properties of textile
  • 1.1 Specifications and or sample of textile material product is confirmed with originator and client
  • 1.2 End use and performance standards expected of finished product are clarified and determined with appropriate personnel
  • 1.3 Sample is analysed to determine type and composition using appropriate techniques, if required
2 Perform preliminary selection and evaluation of dyes
  • 2.1 Preliminary selection of dyes and chemicals and auxiliaries is undertaken with reference to specifications and or previous product dyeing references
  • 2.2 Expected textile production and reproduction processes are identified based on preliminary dye selection and appropriate personnel advised
  • 2.3 Preliminary dye selection is determined for the sample of textile
  • 2.4 Dye selections and specification and recipe are trailed using laboratory-based production facilities and results evaluated against requirements of originator and client, as required
  • 2.5 Dye selection and recipe is reviewed, and re-developed and re-tested as required
  • 2.6 Approval of preliminary dye specification by originator and client is sought prior to implementing limited production run
3 Perform final selection and evaluation of dyes and specification and recipe
  • 3.1 Sampling and testing techniques are selected appropriate to evaluation of product during limited production run
  • 3.2 Tests are implemented using established enterprise procedures and quality standards
  • 3.3 Results are analysed and preliminary dye selection and recipe reviewed, modified and re-tested as required
  • 3.4 Dye selection checked against original client specifications and requirements and enterprise production process and requirements
  • 3.5 Approval of colour specification by originator and client is sought prior to implementing bulk production run
  • 3.6 Environmental requirements and procedures concerned with waste, pollution, storage and recycling of materials are correctly applied at all stages of the process
4 Prepare final dye specification and recipe
  • 4.1 Samples from bulk production run are tested using appropriate techniques
  • 4.2 Results are analysed and dye recipe reviewed, modified and re-tested as required
  • 4.3 Dye specification and recipe is developed, checked and filed in accordance with workplace requirements and industry and quality standards
  • 4.4 Reports and documentation are prepared
  • 4.5 Dye specification and recipe is monitored to ensure continuity and repeatability of colour and test results
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

OHS practices
OHS practices must include hazard identification and control, risk assessment and implementation of risk reduction measures specific to the tasks described by this unit, and may include:
manual handling techniques
standard operating procedures
personal protective equipment
safe materials handling
taking of rest breaks

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects of evidence to be considered
Demonstrates skills and knowledge to:
identify textile characteristics
establish and confirm criteria for tests
set up and calibrate test equipment
develop and plan tests
ensure tests are conducted against specified quality standards
collate, analyse and interpret tests
develop dye formula and specifications
communicate effectively with design team, customers, etc.
maintain accurate records

Consistency in performance
Consistently applies skills and knowledge when:
organising work
completing tasks
identifying improvements
using workplace practices
using OHS practices
recording and reporting accidents and incidents
assessing operational readiness of equipment used and work processes
recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions
completing work systematically with attention to detail without damage to goods and equipment

Resource implications
Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Context for assessment
Assessment may occur on the job or in an appropriately simulated environment.

Interdependent Assessment
This unit may be assessed independently or in combination with other relevant units.
