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.
