Course : Knitting Technology
Course description:
In this course the students will study a brief introduction to basic principles of knitting; basic weft and warp knitted constructions, sequence of loop formation on warp and weft knitting machines. Relation between knitting machines and yarn quality, features and productivity of different types of machines; geometry of loops; control of loop length, fabric weight and dimensions; structure property relations of knitted fabrics
Focus of the course:
The courses mainly focus on the one of important segment of textile technology i.e. knitting process and construction of knit fabric which plays an imperative function to produce garments.
Learning objectives:
In this course you will be able to develop the following program objectives:
1. Problem solves and applies sustainable practices related to fashion and textiles issues.
2. Utilizes a systems approach to design and operational performance, have the technical and relevant process skills, in both analysis and synthesis to be able to exercise technical judgment in decision making.
3. You have the ability to undertake problem identification, formulation and solution.
Learning outcomes:
After completion of the course, students will become aware of the technical aspects of the knit fabric formation, properties and follows:
ü Prerequisites process to produce knit fabric.
ü Different characteristics of knit fabrics.
ü Understanding about physical properties of knit fabrics
ü Identify the manufacturing process at sector and enterprise level.
ü Outline the fundamentals of the knitting process.
Course requirements:
No prerequisite is necessary for this course as this course include principle of knit fabric and basic properties. Introductory study about textile is preferable
Exams:
There will be two class tests one will be before midterm exam and another one after midterm exam based on class lectures.
A one hour thirty minutes midterm examination and two hour final examination administered by the University Examinations Office will be held after lectures have ceased. The final examination covers lectures and assigned textbook readings. Nearer the time, you will be advised of the date, time and venue of the examination by the Examinations Office.
Classroom rules and conduct:
