textiile texting instruments

1. PRINCIPLES OF VARIOUS FIBER
TESTING INSTRUMENTS

2. TEXTLE TESTING
• Testing for FIBERS,YARN,FABRIC and
GARMENT.
• Testing means to check the quality of the
product.
TYPES OF TESTING:-
• Objective testing.
• Subjective testing.

3. TYPES OF ERROR
• Consumer risk.(sample)
• Producer risk.(lot)

4. CONDITIONING OVEN
PRINCIPLE:-
• REGAIN is the weight of the material.
• The weight of the material is measured under
a standard condition.
• The instrument is must calibration.

6. PURPOSE
• To measure the amount of moisture present in
the given material.
• THERMO STAT - to control the
temperature.
• LIMITATIONS - difficult to connect the
perforated tray to physical balance for
normally.

7. • The performance of textile fibers (or) yarn (or)
fabric is differ in wet and dry conditions.
• Moisture regain=wt of water/oven dry wt x
100
• Moisture content=wt of water/total wt of
material x 100

8. SHIRLEY TRASH ANALYSER
PURPOSE:-
• To measure the amount of trash content
present in the cotton fiber.
• TRASH means broken seeds.
• TRASH + COTTON KAPPAS.
• CLEAN COTTON LINT.

9. SHIRLEY MOISTURE METER
PRINCIPLE:-
• The electrical resistance of textile fibers
various with different regain values.

10. DISADVANTAGE
• If the using this instrument is that the dyeing
and chemical treatments alter the electrical
properties of the material and it is not to
possible to calibrate the instrument.

11. BAER SORTER:-
• To measure the fiber length in a old type
model.
DIGITAL FIBRO GRAPH:-
• To measure the fiber length value in digital
form and more accuracy.

12. AIR FLOW AND FIBER FINENESS
• Air flow according to total gape in the base.
PRINCIPLE:-
• Rate of air flow ᾀ 1/surface area of fibers.

13. • A sample of known weight is compressed in a
cylinder to a known volume and subjected to
an air current at a known pressure.
• The rate of air flow through this porous plug
of fiber , related to the fineness of the cotton
fiber is measure.

14. MICRONAIRE
PURPOSE:-
• To measure the fineness of the fiber.
FIBER FINENESS RATING:-
• Below 3 - very fine.
• 3 to 3.9 - fine.
• 4 to 4.9 - average fine.

15. • 5 to 5.9 - coarser.
• 6 and above - very coarser.
FINENESS:-
• Number of the fibers in the yarn is depends on
fiber fineness.
• Fineness denotes the size of cross sectional
dimensions.

16. • Linear density (or) weight/unit length of fiber
is more commonly used index of fineness.
METHOD OF FINENESS MEASUREMENT:-
• Optical.
• Unidimensional.
• Bidimensional.
• Air flow method.

17. COTTON FIBER
CROSS SECTIONAL VIEW:-
• lumen - empty space in cotton fiber.
• Lumen part ↓ maturity ↑ dyeability↑
METHOD OF DETERMINATION OF MATURITY:-
• Indirect method → CAUSTIC SODA SWELLING
METHOD

18. • Direct method →
1. Differential dyeing method.
2. Polarified high method.
3. Causticaire method.

19. ABRASION RESISTANCE
• The Abrasion Tester cum Pilling Tester is used
to determine abrasion as well as pilling
resistance of any type of woven, non-woven,
knitted, and coated fabric.

21. COLOR MATCHING CABINET
• The Color Matching Cabinet is used for visual
inspection of any colored material like textile,
paper, paint, ink, automotive etc.
• Standard Light sources are used for accurate
testing and inspection.
