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
Antimicrobial agents
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
Requirements for Antimicrobial Finishes
Antimicrobials delivery Technologies
Antimicrobials Mode of Action
Controlled - Delivery Systems
Preparation Methods of Microspheres / Microcapsules
Microspheres by Solvent Evaporation
Microspheres by Precipitation Polymerization
Microspheres by Suspension Crosslinking
Microcapsules by Phase Separation
Alkyl ammonium Cations
Formation of chloramines on cellulose.
Few structures of antimicrobial agents
Chitosan
Antimicrobial Activity Tests
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
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
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.
