  General Course Instruction:

  ·         This course is of 3 credit hour so three classes (each class of 1 hour) per week.

  ·         DIU BLC will be the only platform beside regular classes.

  ·         Every students must be enrolled in DIU BLC.

  ·         DIU BLC is the platform for submitting assignment & presentation. Presentation may prepared in video format so that Students can upload it on BLC.

  ·         Best three class test should be counted for final evaluation among four class test.

  ·         Sometimes students will get opportunity for carrying bonus marks by engaging themselves in forum discussion, instant quiz and other group activities.

  ·         Course will be conducted according to course plan. So Students are requested to follow course instruction. 

  General Course Description : 

  Course Title: Textile Physics

  Course Code: TE-317

  Credit Hours: 3 (Theory, 3 contact hours per week) 

  Course Level: Level 3 Term 1

  Rationale: 

  All courses reflect curriculum for excellence values, purposes and principles. As a

  Textile Engineer, every student should have the ability to relate physics and textile fiber. They should know about effect of bending, torsion, friction, heat on textile material .After this course; students will have a brief idea about implementation of physics on textile fiber.
  
  Course Objectives :
  

  By the end of the course it is expected that the students will be able to,

  • Explain about the mechanical properties (Tensile, Flexural, Torsional, Frictional) of the textile materials.
  • Explain about swelling, optical & thermal properties.
  • Know about static charge & its formation and effects on textile materials.
  • Know about physical structures of the fibres.
  • Learn about yarn geometry & fabric geometry.
  • Learn about yarn jamming & crimp% in to the fabric.

  Course outcomes (Cos):
  

   After completing the course students will able to:

  ·         Learn the mechanical properties of textiles, including tensile, flexural, torsional and frictional properties and identify the difficulties of working with fibres, yarns, fabrics, and garments having poor mechanical properties.

  ·         Learn about swelling, thermal and optical properties, and its effects in textiles processing.

  ·         Identify the physical structure of textile fibres and know the influences of fibre migration during the spinning process.

  Analyze the geometry of yarns and fabrics which has more significance in setting required cover factor, air permeability, drape ability and other properties of cloths.

  Midterm Examination	25
  Final Examination	40
  Total Points	100

   

  Class Attendance

  Class attendance is an essential requirement and a student attending all the classes will be awarded 07 points.

  Class Test

  Short or MCQ questions must be answered in 30 minutes. Number of class tests would be 3. Class tests must be attended and makeups would be allowed only under special circumstances with a depreciation of 10% points.

  Assignment

  This will be assigned on every topic for which a student will work regularly and then submit an assess able document through Google Classroom or BLENDED Learning Centre. Assignments must be submitted by the given deadline or special permission must be requested before the due date.

  Presentation

  Power Point presentation of 5 minutes duration on selected title to be delivered and relevant questions should be answered satisfactorily before the students and teachers in the classroom for assessment before Final examination. Organize and practice your presentation in advance; make sure you don’t exceed the time limit.

  Final Examination

  This examination will consist of short and essay type questions. Questions will be provided and must be answered in 120 minutes. Makeups would be allowed only after acceptance of application and on payment of prescribed fees.

  Letter Grade 

  Daffodil International University has adopted Uniform Grading Policy as suggested by University Grants Commission of Bangladesh. Final grades assigned for this course will be based on the percentage of total points earned and are assigned as follows:

  Letter Grade	Percentage	Numerical Equivalent	Performance
