Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

It is strongly advised that students complete the following units prior to enrolling in Select dyes and develop dye specification and recipe for production

MKTG 5756C Identify fibres, yarns & textile

Course Description

This unit covers the skills and knowledge associated with selecting, developing and testing dyes, chemical and auxiliaries and developing dye specifications and recipes for the dyeing of textiles for self and others. Textile materials for which dye specifications are developed include fibres, yarns and fabrics, and tasks may involve individual and group activities.

1.3 Sample is analysed to determine type and composition using appropriate techniques, if required

Element:

2 Perform preliminary selection and evaluation of dyes

Performance Criteria:

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

Element:

3 Perform final selection and evaluation of dyes and specification and recipe

Performance Criteria:

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

Element:

4 Prepare final dye specification and recipe

Performance Criteria:

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


Learning Outcomes


On completion of this course students will be able to demonstrate skills and knowledge to identify the correct dye class for a given fibre, to formulate appropriate dye recipes and to successfully apply the dye to fibre, yarn or fabric in accordance with correct OHS procedures.


Details of Learning Activities

Blended learning, consisting of classroom activities, practical workshops, individual and group presentations and individual preparation of a comprehensive folio of dye samples.

Overview of Assessment

To achieve successful completion of this course students must demonstrate an understanding of all elements of Competency.
Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks.

Assessment may  incorporate a variety of methods including in-class exercises, quizzes, written reports, documentation of technical requirements, practical problem solving exercises and practical applications of knowledge. As well as in-class activities you will be required to undertake research and assessment practice outside of regular class time and participate in formal assessment tasks.

Detailed course information and assessment requirements will be available in the first week of class.
Specific details will be explained during scheduled classes.

Students are advised that they are required to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

Work that has not been authenticated during class as students own work will not be considered for assessment.


Assessment Tasks

Textile Colouration Quiz. A question and answer overview of textile colouration, to be completed by students for in-class review.


‘3 fabrics’ dyeing process and written report. A piece of fabric will be allocated in class and each student is expected to dye it to a pre-determined colour. Each student is to select the appropriate dyes and chemicals required to successfully dye the fabric to the desired colour using the most appropriate method learnt in this semester. The process used to produce the end result must be documented and described precisely in a written report covering what was done and why it was done that way.


Report on a source of natural dyes. Students select a natural dye stuff to investigate and research. Relevant research including history, illustrations and examples are to be included in an introductory 1 page report. Individual reports to be compiled into a class discussion board on black board.


Observation Checklist. Ongoing observation of Occupational Health and Safety demonstrating that set tasks, equipment maintenance and clean up are conducted by each student in accordance with OH&S practices.


Client Project. In collaboration with a selected client each student is required to conduct a series of dye tests towards achieving a specified colour and complete a written report, including dye recipes, procedures and specifications.


Technical Folio of dye samples.  A comprehensive folio is to be presented neatly, clearly and concisely showing all class notes collected during the semester together with correctly labelled samples for all different dyes. Any additional notes and further research undertaken is to be included.
