Textile Fiber || General Properties Of Textile Fiber

We know that, fiber is that which is 100 times longer than its width. A fiber which could be spun for yarn production that is called textile fiber. Textile fiber is used for producing different types of woven, non-woven and knitted fabrics.

Textile fiber which is used for yarn or fabric production that should have some properties. Generally physical, chemical and structural properties is important to know for know the textile fiber. Here, I have given a list of properties name which is required to know.

Physical Properties: I have given the physical properties name with their unit. A textile fiber should have the following physical properties. They are as follow:

  1. Tenacity / Specific Strength (g/den)
  2. Length (cm/inch)
  3. Fineness (mic-value)
  4. Moisture Regain (MR %) and Moisture Content (MC %)
  5. Specific Gravity (g/cc)
  6. Elongation (cum/inch)
  7. Elastic Recovery (%)
  8. Initial Young Modulus (g/den)
  9. Breaking Length (km)
  10. Extension (%)
  11. Maturity
  12. Swelling R Water Relation %
  13. Static Electrification
  14. Glass-Transmission Temperature (T9)
  15. Crystalline Melting Point (Tm)
  16. Discoloration
  17. Specific Heat
  18. Burning Behavior
  19. Thermal Conductivity
  20. Pilling Behavior
  21. Limited Oxygen Demand (LOI %)
  22. Degradation

Chemical Properties: To identify a textile fiber, following properties plays an important role. Chemical properties are-

  1. Chemical Composition
  2. Effects of Acids
  3. Effects of Alkalis
  4. Effects of Organic Solvents
  5. Effects of Insects
  6. Effect of micro-Organism

Structural Properties: All of textile fibers have its own structure by which it can be identify.

I.  Fine Structure and Appearance

II.   Micro Structure

  • X-Sectional View
  • Longitudinal View

So, when we will describe about any textile fiber we have to determine the above physical, chemical and structural properties.
