3. Microbe: is a living body not visible with naked eye can be seen
under the microscope such as bacteria, fungi, mildew, mold and
yeasts, found everywhere in nature.
 Conditions for their growth on human bodies are suitable
temperature, moisture, dust and receptive surface.
Effects of micro-organisms on textiles
 bad odour
 discoloration or staining of the fabric
 slick slimy hand
 loss of elasticity and tensile strength
Introduction

4. Antimicrobial agents

6.  to avoid infection by pathogenic micro organisms.
 to control growth of microbes on fabrics worn close to skin
 to arrest metabolism (break down) in microbes in order to
reduce the formation odour.
 safeguard the textile products from staining, discolouration
and loss in strength and othter useful physical and chemical
properties
NEED OF ANTIMICROBIAL FINISHES

7. Requirements for Antimicrobial
Finishes

8. Antimicrobials delivery Technologies

9. Antimicrobials Mode of Action

10. Controlled - Delivery Systems

11. Preparation Methods of Microspheres /
Microcapsules

12. Microspheres by Solvent Evaporation

13. Microspheres by Precipitation
Polymerization

14. Microspheres by Suspension
Crosslinking

15. Microcapsules by Phase Separation

16. Alkyl ammonium Cations

17. Formation of chloramines on cellulose. Few structures of
antimicrobial agents

18. Chitosan

19. Antimicrobial Activity Tests

20. Microbes can be a source of many problems to human beings,
 Unpleasant Body Odour
 Physical Irritation,
 Allergy,
 Toxicity(poisoning)
 Infection And Diseases.
Dust mites are eight legged creatures and occupy the household textiles
such as blankets bed linen, pillows, mattresses and carpets. dust mites
feed on human skin cells and liberated waste products can cause
allergic reactions and respiratory disorders.
Effect of Microorganisms on Human
being

21.  protection of textile from decay or degradation
 control of staining caused by microbial growth
 added freshness to the fabrics
 elimination of smells created by microorganisms
 protection of human health from diseases
Benefits of Antimicrobial Finishes

22. In general effects of micro-organisms on textiles results bad
odor, discoloration or staining of the fabric, slick slimy hand,
loss of elasticity and tensile strength also they affects Physical
Irritation, Allergy, Toxicity (poisoning), Infection And Diseases
on human being so we should remove this by using anti
microbial and by storing appropriately.
