ECOFINISHING OF FABRIC

ANTI-BACTERIAL AND ANTI-MICROBIAL FINISH



INTRODUCTION

Increasing global competition in textiles

has created many challenges for textileresearchers and industrialists. The rapid

growth in technical textiles and their

end-uses has generated many

opportunities for the application ofinnovative finishes.

Anti-bacterial and Anti-microbial finishes

are one of the innovative finishes.

The use of natural products such aschitosan2 and natural dyes3-5 for

antimicrobial finishing of textile

materials has been widely accepted.



NECESSITY OF ANTIMICROBIAL AND

ANTIBACTERIAL FINISHES

To control microorganisms and

bacteria.

To reduce odour from perspiration,

stains and other soil on textilematerial.

To control spread of disease and

danger of infection.

To control the deterioration oftextiles particularly fabrics made

from natural fibre caused by

mildew.



ANTIMICROBIAL AND ANTI BACTERIAL

FINISHING METHODOLOGIES

The antimicrobial agents can be applied to the textile

substrates by exhaust, pad-dry-cure, coating, spray

and foam techniques.

The substances can also be applied by directly adding

into the fibre spinning dope.

Treating the fibre with resin, condensates or cross

linking agents.

Coating the fibre surface

Chemical modification of the fibre by covalent bond

formation



DIFFERENT TYPES OF ANTI- MICROBIAL AND

ANTI-BACTERIAL FINISHES FOR FABRIC

EUCALYPTUS Oil: Eucalyptus (Eucalyptus radiate) has

terrific cleansing properties. Eucalyptus oil has been

shown to fight against infection causing bacteria, fungi,and virus very effectively.

AZUKI BEANS: The water extracts of green, black and

red coloured Azuki beans shows antibacterial effectagainst Staphylococcus aureus.



SERICIN: Silk sericin is a natural

macromolecular protein formulation because

of its pest repellent properties. Most of the

sericin are used in textile application as an

antimicrobial agent.

CHITOSAN : Chitosan and its derivatives have

received a lot of biodegradable polymer.

.Chitin is one of the attention as antimicrobial

agents for use in textiles.



ALOE LEAF: Contains aloe vera also possesses antifungal

and antibacterial 75 nutrients and 200 active compounds,including properties.

NEEM EXTRACT:It has been recognized as one of the most

promising sources of compounds with insect control,

antimicrobial and medicinal properties. PRICKLY CHAFF FLOWER: Prickly chaff flower

is one of on textile substrates. It showed anti-microbial activity

on both the Gram positive and Gram negative bacteria.



TULSI LEAVES: The main constituents of tulsi are eugenol

which act as a antimicrobial agent. During studies it has been

seen that it has good effect on cotton.

TEA TREE: It has been recognized as a natural medicinal

product. It has antiseptic, dermatological and anti-fungal

benefits and can be also used to fight infection.

OTHER HERBAL PRODUCTS : The turmeric also imparts

antimicrobial property because of its bactericidal activity.



CONCLIUSION

There is a vast resource of natural antimicrobial

agents, which can be used for imparting useful

antimicrobial property to textile substrates.

Although, there are many cited literature, wherein

efforts have been made to exploit these ecofriendlybioactive natural products for textile application, but

there are very few studies which have carried out

systematic in-depth investigation.
