Academy of Technical and
Art Applied Studies Belgrade

Textile Testing Course code: IST 003059 | 6 ECTS credits

Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 3
Semester: 5
Requirements: Knowledge of basics of mathematics, textile fibers, and textile material properties.
Goal: Introducing students to the properties of textile materials with a particular focus on their practical application. Training students to choose appropriate raw materialy; testing fibers, yarns and fabrics at the laboratory. Introducing students to the modern physical, chemical and mechanical methods for testing textiles. Training students to use statistical processing of the data obtained through measurements and testing with the goal of managing the production process.
Outcome: Upon fulfilling their pre-exam obligations and passing the exam, the students are trained to successfully perform textile testing and provide and evaluation of quality.
Contents of the course
Theoretical instruction:
  1. Methods and classification of testing. Standards in the textile industry. Fiber, yarn and fabric sampling.
  2. Introduction to the statistical processing of data in textile. Statistical set. Average values and dispersion measurements. Ranked data. Graphical and table representation of results. Asymmetry and excess.
  3. Interval estimation. Histogram. Graphical representation of results. Sample-based statistical evaluations. Humidity. The effect of humidity on textile.
  4. Fabric moisture. Conditioning the textile material. Testing for the presence of foreign matter in textile.
  5. Testing fiber length.
  6. Testing fiber fineness. Cotton maturity levels.
  7. Macroscopic fiber structure. Fiber resistance to force.
  8. Yarn testing. Yarn count. Testing yarn twist. Yarn irregularity. Yarn hairiness.
  9. Mechanical properties of yarn. Testing yarn strength, yarn tension, and resistance to abrasion.
  10. Testing textile surfaces. Geometric characteristics of fabric (length, width and thickness). Fabric mass and density. Calculating fabric mass.
  11. Mechanical characteristics of textile surfaces (strength, resistance to puncture, abrasion, seam slippage and creasing).
  12. Testing textile surfaces. Properties which influence wearing comfort (permeability for air and water vapor, fabric hygroscopicity).
  13. Testing textile surfaces. Color fastness.
  14. Fabric composition.
  15. Visit to the textile institute.
