AKTU Textile Testing-I (BTT501) Syllabus PDF – B.Tech 3rd Year

Course Outcome: After completing the course student will be able to:

CO1 Understand importance of textile testing and apply statistical techniques for collecting samples.

CO2 Understand the concept, significance and effect of environmental conditions on properties of textile materials.

CO3 Understand methods of measurement of various physical properties of cotton and man-made textile fibres CO4 Understand the concept of yarn count and twist and its methods of measurement.

CO5 Understand the concept of yarn unevenness, yarn imperfections, classimat faults and hairiness and its measurement techniques.

Unit (1): Introduction of textile testing, sampling techniques, random and biased sampling, square, cut square, zoning technique, selection of sample for testing, grading of cotton fibre with respect to staple length, understanding of national and international testing standards.

Total Lectures Required = 6 Unit (2): Atmospheric conditions for testing, absolute & relative humidity, moisture regain &moisture content, importance of moisture in textiles, measurement of moisture regain & content, effect of moisture on physical & mechanical properties of textile material, factors affecting the regain, correct numerical weight, oven dry weight, Dry and wet bulb hygrometer, control of testing room atmosphere.

Total Lectures Required = 6 Unit (3): Measurement of cotton fibre properties- length, length uniformity, span length, upper-half mean length, fineness, strength, maturity, trash, colour by conventional methods and using HIV, AFIS, determination of Fibre Quality Index, Spinning Consistency Index.
