AKTU Carpet & Textile Testing - I (BCT501) Syllabus PDF – B.Tech 3rd Year

Course Objectives

To learn the importance of testing, role of environmental conditions on testing results, measurement of fibre length, fibre fineness, fibre maturity, yarn twist, yarn irregularity and their effects on end product quality. Also, to get an understanding of the terminology related to construction and testing of carpets and to acquire knowledge on fire testing of carpets.

Objectives of Testing, selection of samples for testing, Random and biased sampling, Principles of sampling for fibre/yarn/fabric/carpet testing, Effect of moisture on different fibre properties, moisture content & regain; measurement of atmospheric conditions, Brief description and working principle of moisture meter.

Importance of fibre length measurement, Concept of Baer Sorter Diagram, Analysis of effective length, modal length, Average length and short fibre% using Baer Sorter Diagram, Concept of span length and Uniformity ratio. Importance of fibre fineness measurement, Determination of fibre fineness using air flow method, Fibre maturity: methods of determination of fibre maturity. Salient features of modern testing instruments like HVI, AFIS, WIRA FDM.

Importance of yarn Twist & its measurement, Measurement of yarn hairiness, Type of irregularity and its expression; Index of irregularity; limit irregularity; Principles of measurement of Evenness Testing (Sliver, Rove & Yarn), nature of irregularity; periodic irregularity, random irregularity.

Terminology related to construction and testing of carpets, Measurement of carpet thickness, Pile height, Knots per square inch, Tuft density, Carpet wear & abrasion, Thickness & compression recovery, Tuft Withdrawal force etc.

Terms & definitions related to Fire Testing of carpets, Factors affecting behavior of carpet against flame, Various Carpet Flammability Testers
