This document discusses various textile testing methods. It provides details on breaking strength testing, including that it is mainly used for woven fabrics to test unidirectional strength. It also discusses the importance of breaking strength testing for end uses like safety belts. Abrasion resistance testing and its importance for fabrics used in garments is covered as well. Finally, it summarizes color fastness to dry cleaning testing and the equipment used.

3. BREAKING STRENGTH

4. BREAKING STRENGTH
• Mainly used for woven fabric because the tests
are unidirectional and woven fabrics have
unidirectional yarns.
• Factors that produce a strong fabric include fiber
content, yarn size and type, weave, and yarns per
inch.
• Breaking strength is expressed in pounds and the
elongation is expressed as a percent and in both
cases a number of warp tests and weft test are
performed.

5. IMPORTANCE OF BREAKING STRENGTH
TEST
• Breaking strength is important in various end
uses such as automotive safety
belts, parachute harness and pants.
• Breaking strength can also be used to test the
effects of destructive forces upon a woven
fabric including sunlight, abrasion, laundering
etc.

6. ABRASION RESISTANCE

7. ABRASION RESISTANCE
• Abrasion resistance is the wearing away of
any part of a material when rubbed against
any other material.
• Abrasion resistance is the wearing away of
any part of a material when rubbed against
any other material.

8. ABRASION RESISTANCE
• Garments that are made from fibres that
possess both high breaking strength and
abrasion resistance can be worn often and for
a long period of time before signs of physical
wear appear.. Nylon is extremely high in
abrasion resistance so it is used widely in
action outer whereas Acetate has poor
abrasion resistance so it does not last long
when used for lining in jackets and coats.

12. Color Fastness To Dry Cleaning
•

13. Color Fastness To Dry Cleaning
• Color may change due to dry cleaning too.
• This test indicates what will happen to the color
of textile materials after repeated commercial dry
cleaning.
• Perchlorethylene is used in the test:
• Commonly used dry cleaning solvents.
• It is slightly more severe in solvent action.
• A color that may get affected by perchlorethylene
will not get affected by Stoddard solvent
(petroleum base).

14. Color Fastness To Dry Cleaning
• Device used for this test is the launder-
• ometer.
• Dry cleaning solvent instead of water is used
as liquid.
