11. FUNCTION OF MOISTURE MANGEMENT
Regulation of body temperature – when the
human body core temperature exceeds 37 oC,
sweat is produced. Transporting the sweat
away from the skin & evaporating it to the
atmosphere, reduces body temperature
Control cloth weight increase – absorbing the
moist generated by the body increases cloth
weight, making it uncomfortable & with a
negative effect on performance. Moisture
management avoids this effect
Moisture
management
has the
following
functions:
Reducing Skin Damage

12. MMF model in clothing comfort
The one-way moisture capillary process.
Simple model of the moisture transfer of sweat in finished
fabric
• hydrophobic chemical finish applied to the
inner side (next to skin) of cotton fabric
• The dual functionality of the surface enhanced
capillary effects

13. Soil release finish
Fabric treated with soil release finish particularly
suited
• Active wear
• Industrial uniform
• Napery
• Other market area where soil release is required

14. Role of Soil release finish
• Protection from soil redeposition during
laundering
• Absorbency /or transport of liquid water
• Fabric that increased absorbency
provide more comfortable under
• Hot & Humid condition
• So it is also called comfort finish

15. Softening Finish
• With chemical softeners, textiles can achieve an
agreeable,
 soft hand
 (supple, pliant, sleek and fluffy),
 some smoothness,
 more flexibility
 and better drape and pliability.
• To achieve the desired quality of fabric handle or softness

16. INTRODUCTION
• The hand of a fabric is a subjective sensation felt by the skin when
a textile fabric is touched with
– the finger tips and gently compressed
• The perceived softness of a textile is the combination of
several measurable physical phenomena such as
1. elasticity,
2. compressibility
3. and smoothness.
• During preparation, textiles can become embrittled because
– natural oils and waxes or fibre preparations are removed.

17. • Softeners provide their main effects
» on the surface of the fibres.
• Small softener molecules, in
addition,
 penetrate into fiber
 provide an internal plasticisation of the fibre
forming polymer
Basic Mechanism
•Softeners orient themselves
toward the fibre creating a new
surface consisting of molecular
chains that provide the
characteristic softening and
lubricity.
•Small softener molecules
penetrate the fibre and provide
plasticisation of fibre forming
polymer

18. Crease recovery finish
The main objectives of wrinkle free finish keep the
fabric flat, smooth & free from undesirable creases
that helps in clothing comfort as well
• Improve drapability, resilience & handle property
of textile
• It imparts smoothness & quick drying properties which
improve hand properties of cloth

19. Medical cosmetics & Odor resistance finish
• Antimicrobials enhance the functionality & value of
textile products by keeping the microorganism that
cause odor & fiber degradation
• Textile goods (natural fibers), is an excellent media
for microorganisms to grow, because of their large
surface area & ability to retain moisture

20. • Several chemicals (such as inorganic
salts, organometallics, phenols &
thiophenols, onium salts, antibiotics
etc. ) have excellent antimicrobial
property
• chitosan is an excellent & eco-
friendly chemical which can provide
better odor comfort of textile clothing

21. WHERE WE ARE ???
