Overview of Herbal garments…
• In this work, an attempt is made to impart medicinal value
to cotton fabrics
• There is historical evidences that the great Tamil siddhar
“Agastya Muni” & “Thiruvalluvar” taught the basics of
medicinal cloth.
• In herbal garments development, all stages of processing
were done in a natural way
• Curative herbal garments have been developed to cure
Allergic Dermatitis, Psoriasis, Asthma, Liver Disorders,
Head Ache, Joint pain and Sinus Trouble/ Common cold.
Advantages of Herbal/Curative Garments
• It is anti-allergic, anti-microbial and has anti-septic
properties and dyes used are eco-friendly.
• Provides manure to the soil & plants because the waste
generated by herbal dyes would serve the same purpose
• Benefit children and the future generations by stopping
Air, Water and Soil pollution

Clinical Trials
Pre-Processing
• The material is first wetted in cold water solution
containing a natural mild detergent (10%) and left in this
bath for 24 hours.
•
The Scouring process was carried out in the solution
containing 15% natural scouring agent at the boiling
temperature for an hour and washed till the material
brought to neutural PH.
Natural Bleaching
• The scoured cotton fabrics
are exposed to direct
sunlight with use of a
natural grass base and
animal manure, which
carries out the natural
bleaching process.
• No chemicals are used in
this process.

Herbal Extraction
• Herbals are choosen according to the nature of the disease.
• Then it is powdered or wet ground then boiled for selected
duration depending on the hardness of the material.
•
Flower and fruit materials are soaked in sufficient amount of
water for the required duration and then the solution was
drained or filtered.
HERBAL EXTRACT APPLICATION PADDING
• Medicinally rich herbal extracts
are used for the
development of curative fabrics using Pad-Dry-Cure
technique.
•
The padding bath is set with required amount of water
and the herbal extract solution is poured into the padding
bath and the required temperature is maintained.
• The fabric is treated in the padding bath and Seven
varieties of curative fabrics were developed
• The process parameters varies according to the herbals
used .

DIFFUSION OF HERBAL MOLECULES
INTO THE SKIN
• The
herbal
molecule
responds to the warmth of
human skin and is
subsequently
absorbed
into the body through
sweat pores , after which it
gives
the
desired
medicinal quality.
• The cloth has to be in
direct contact with the
patient’s skin to work
Clinical Trials
• The Performance of the developed curative garments were
evaluated by conducting clinical trials at a Nature Cure Centre for
seven weeks.
• Patients with Allergic Dermatitis, Psoriasis, Asthma, Liver
Disorders, Head-Ache, Joint-Pain and Sinus Trouble/ Cold were
selected for the trials
• The patients were instructed to carry out the washing of the
curative garments with natural mild detergents
• Detailed feed back from the patients and the Doctor were collected
every week regarding the performance of the curative garments.
Testing of Curative Fabrics
•
AATCC Standard tests (American Association of Textile
Chemists and Colourists- Standard tests)
- Agar Diffusion Test,
- The Combined AATCC 100 and Hohenstein
modified test method: challenge test
– JIS L 1902
- Wash durability test (AATCC 124)
•
ISO Standard Wash fastness test
- (ISO-105 C06 A1M- washing at 40°C)

Evaluation of antimicrobial activity of curative
fabrics with agar diffusion test
•
The preliminary assessment of the antibacterial activity
of the curative fabrics confirm that the maximum
efficiency was found in the Neem-Portia treated fabric
followed by Tulasi-Malabar nut and Turmeric-Neem
treated fabrics.
•
The tests clearly confirm that the treated fabrics were
efficient in controlling the gram positive organism than
the gram negative organism.

Evaluation of antimicrobial Activity of curative fabrics with
Combined AATCC 100 And Hohenstein modified test method:
Challenge test JIS L 1902
• The results of the evaluation of antimicrobial efficacy
test shows that % bacterial reduction of curative fabrics
varies from 82-98% in the case of Staphylococcus
aureus (representation of gram positive bacteria) and 6882% in the case of Escherichia Coli (representation of
gram positive bacteria).
•
The results clearly shows that the curative fabrics has
got excellent antibacterial activity against the major
diseases causing bacteria such as Staphylococcus aureus
and Escherichia Coli.

Evaluation of wash durability of curative fabrics (AATCC 124)
• The results shows that the retention of anti microbial
activity was noticed up to maximum of 12 washes in the
case of Neem-Portia Tree fruit treated fabrics and followed
by Turmeric – Neem treated fabrics.
•
The results shows that the bonding of the herbal molecules
in the curative fabric structure is moderate. The above
property will help the herbal molecules in the curative fabric
to get diffused into the skin of the patients easily.

Evaluation of Wash Fastness of Curative Fabrics
(BS EN ISO-105 CO6 A1M- WASHING AT 40°C)
• The test results shows that all the above mentioned
curative fabrics are having low to medium wash fastness
properties.
• Since the above fabrics are mainly intended for curative
purpose, the low-medium fastness properties of the above
fabrics will help the herbal molecules in the curative
fabrics to get easily diffused in to the skin of the patient.

Evaluation of Clinical Trials
• The results of clinical trials shows that the curative
performance of the garments in all the cases were found to
be significant.
• The results shows that the maximum curative performance
was noticed in the case of Euca-Head band followed by
Turmo-Neem T-Shirt and Tulasi T-Shirt.
• The antibacterial assessment of the treated fabrics
confirmed the correlation between the curative property
and its antibacterial activity.
• The bio-chemical properties of the herbal extracts can be
elucidated and its exact role in the mechanism of curing
the disease can be well established.
CONCLUSIONS
•
100% Cotton fabrics (woven / knitted) have been selected and
are pre-processed without using any chemicals at any stage of
the pre-processing.
•
The identified herbal extracts of different formulations have
been derived and applied to the cotton fabrics by Pad-DryCure technique.
•
The developed curative fabrics of seven different varieties
have been tested as per AATCC Standards & ISO Standards
•
The antibacterial assessment of the treated fabrics confirmed
the correlation between the curative property and its
antibacterial activity.
Conclusions Contd…..
• The bio-chemical properties of the herbal extracts can be
elucidated and its exact role in the mechanism of curing the
disease can be well established.
• The results of the clinical trials shows that the curative.
performance of the garments in all the cases were found to be
significant.
