Module summary

This module will cover material parameters, process steps and technologies employed to convert fibres (staple/filaments) into yarns, in the context of global environmental, social, and economic impacts. You’ll be able to classify yarn in reference to intended application, demonstrate methodical understanding of the manufacturing process, and explore the key methods to assess yarn quality and its implications on product performance. This module will also cover the sustainable and technological innovations and the future direction of the research/industry.

Objectives

The objectives of the module are to
1) introduce yarns, their types and applications, and role in the textile manufacturing chain;
2) introduce fundamental concepts of key staple and filament yarn manufacturing technologies and achieved yarn structures
3) understand the structure-property relationships of yarns and the impact of material and yarn manufacturing variables on the properties of the yarns and subsequent textiles;
4) provide opportunities for students to develop key skills in manufacturing, testing and characterisation of staple and filament yarns.

Learning activities are varied. To achieve objective 1 and 2, students will learn key principles informed by a series of lectures. The objective 3 will be covered by lectures and seminars. To achieve objective 4, there will be laboratory sessions and industrial visit.

Learning outcomes

On successful completion of the module students will have demonstrated the following learning outcomes relevant to the subject:
1. Classify yarns according to manufacturing technology and in reference to intended application.
2. Describe the processes used for manufacturing and testing/characterising yarns.
3. Explain the effects of the main material and manufacturing variables on the characteristics of the yarns produced,
4. Recognise the role of yarn manufacturing in the use of innovative and/or sustainable and/or recycled materials.

On successful completion of the module students will have demonstrated the following skills learning outcomes:
5. Problem solve by inferring solutions to technical challenges associated with the formation of yarns.

Opportunities for Formative Feedback

1) Formative Assessment 1 – Online MCQs Real-time assessment technology (such as Mentimeter) will be employed to embed MCQs/short questions throughout the module lectures.
2) Formative Assessment 2 – Mock Class Exam This activity will help students to prepare for the exam and promote assessment literacy. The feedback will be given by peers, with the aid of model answers. The peer feedback is known to encourage deep learning.
