ANTI-MICROBIAL & ANTI-INSECT FINISHES

AGES
The textile materials are treated with anti-microbial and anti-insect finishing agents to :

a) protect the wearers or users of the textile product for aesthetic, hygenie or medical propose against
bacteria, dermatophytic fungi yeasts, viruses and other deleterious micro-organisms.
b) protect the fiber and the textile structure from bio-deterioration caused by mole, mildew and rot
producing fungi, and
c) protect the textile from insects and others for fibre preservation. Finishes that are employed for (a)
may be classified as either antibacterial and or antimycotic (antifungal). Those in the second end use
group (b) are commonly called anti-microbial or rot or mildewproofing finishes, while those in third
group (c) are denoted as anti-insect or more specifically mothproofing finishes when used to protect
wool fibers.
Different types of fibres have different susceptibilities to biological attack. Cellulosic fibres are usually
prone to attack by rot and mildew producing fungi while wool is susceptible to insect attack by moths and
carpet beetles. Both natural and synthetic fibres are susceptible to contamination and growth of patho-
EXECUTIVE P
genic and parasitic bacteria, fungi, viruses and microorganisms. The effect of biological agents on textile
is important for end use performance in three areas. Textiles will have desirable aesthetic qualities if they
can supress odour causing bacteria and other type of odour causing microorganisms. The hygienic and
medical effectiveness of textiles is required to prevent the growth of dermatophytic fungi (those that
cause skin diseases), pathogenic and potentially lethal microorganisms on fibers and to prevent their
infestation by insects.

To impart anti-microbial, anti-odour finish the following fabrics can be treated with ANTIMICROBIAL ZE.
- Sportswear, Socks, Uniforms; - Sheets, Towels; - Medical Disposable and - Carpet & Upholstery
APPLICATION

Anti-microbial ZE (1.0%) is applied to textile by exhaustion and pad-dry technique.
The effectiveness of treatment to control odour, growth of bacteria and durability during washing is
clear from the following two tables.
