The green chemistry or eco-friendly finishing one of the most
important considerations of the environmental requirements and
related legislations as important properties in the development of
textile industries. Our research is a trail to get a special ecofriendly bioactive performance of the cellulosic textile products
via microencapsulation technique.
Microencapsulation an interesting actual and probable future
trend for finishing, characterized by a long lasting, slow
continuous release and transfer of products to the human skin is
filling microcapsules with active agents(e.g. fragrances,
cosmetics, vitamins, and drugs and dyes are encapsulated in
the biopolymers e.g. Chitosan) and fixing them on the surface
of the fabric.
As a trail to get an eco-friendly finished product using:
Unconventional effectively (anti-microbial – anti-odour…) ecofriendly product (agriculture or marine algae and plants) as/or
leaves flowers pastes of plants & extract their effective alkaloids
or dyes via microencapsulation technique & other cores.
1- Collection of some agriculture plants and marine algae and
grass taking into consideration the collection period. The
Pelargonium hortorum selected as an agriculture plant,
Colpomonia sinousa, Ulva fasciata as algae. Helophelia
stapilecea as a sea grass.
2- Extract their active ingredients then identify the active
compounds included in their extractions. 3- Study the bioactive performance of the extractions
4- Encapsulation of active extracted ingredients using ecofriendly shell materials, the microcapsules shape and size
detected by TEM microscope and optical microscope) and
scanning microscope was used to evaluate microcapsules
on the surface of the fibers.
5- Apply the encapsulated products on cellulosic based textile
then the bioactive performance of treated samples
evaluated before and after washing cycles according to
antibacterial and anti-inflammatory stander methods.
6- Some samples post treated by 2% citric acid and others by
1% binder (Printfix binder MTBEG liq.)then the bioactive
performance of these samples evaluated before and after
washing cycles according to antibacterial and antiinflammatory stander methods.
7- The main results of this study mentioned below:-
a) The microcapsules were successfully prepared using
ethanolic extract of marine organisms and pelargonium
as a core material, sodium alginate and mybro gum as
b) The microencapsulated extract of different core
materials recorded a high antibacterial and antiinflammatory activity but the pelargonium extract gets
the highest results.
c) The samples post treated by citric or binder get higher
results than those treated by microcapsules only and
those post treated by citric recorded results higher than
post treated by binder (Printfix binder MTBEG liq.).d) The durability against washing cycles were examined,
the samples post treated with citric or binder (Printfix
binder MTBEG liq.) were durable to washing cycle
than the samples treated with microcapsules only.
e) The physico-mechanical properties of the samples
were evaluated before and after treatment. Tensile
strength, roughness properties of the samples enhanced
after treatment, but the stiffness was slightly increased
8- The optimum treatment condition applied on wound
dressing which recorded marked antibacterial activity after
4, 8 and 24 hours.
9- Whiteness and color strength of samples evaluated before
and after different treatment conditions and both affected
slightly by treatment.
10-Four designs of clothing as well as their patterns were
performed, using treated fabrics then printed by different
printing designs as end use of our work.
