Description Today eco-friendly has become the buzz word and eco-friendly fabrics are given
paramount importance. The less exported natural fibres belonging to bast and leaf fibre
category are now receiving greater importance in the context of biodegradability and
eco-friendly nature. One such eco-friendly fibre is the banana fibre which has high
potential as a textile fibre. However, improvement in characteristics i.e. required to make
it suitable for various end uses. As the fibre is extracted from waste, the farmers will be
benefited through extraction and sale of the fibre. With the above concept, this study was
undertaken with the major objective of developing eco-friendly banana blended textiles.
The use of enzymes in textile wet processing was well taken due to safety, energy
water conservation and environmental responsibility that make its use more prevalent.
Hence, enzyme treatment for banana fibre was considered to improve its pliability.
Accordingly softening treatment was carried out on banana fibre in order to impart the
smooth feel, lusture and handle of the fibre. Popular varieties of banana in Andhra
Pradesh namely Pusavalli, Amruthapani, Bontha, karpura and Chakarakeli were
considered for study and four laboratory grade cellulose enzymes such as Sibasof,
Microsil, New smooth and Biozin (Britacel Limited, Mumbai) were selected for study.
Three concentrations of enzyme of 1%, 1.5% and 2% were selected based on the
minimum and maximum recommended levels of enzyme concentration by the
manufacturing company, Britacel.
Based on subjective and objective evaluation of the treated fibre, new smooth
enzyme was selected and concentration levels were also optimized. Among all the fibre
varieties pusavalli variety was found to have better physical characteristics before and
after pretreatment. Raw fibre was processed to get yarns that were used for making
control fabrics. Enzymes treated fibre was processed separately to produce yarns that
were used for making treated fabrics.
The performance characteristics of the enzyme pretreated and control fabrics of
banana and its blends were assessed by subjective and objective evaluation techniques.
The test fabrics were subjected to various laboratory tests to evaluate the geometrical,
handle, comfort, absorbency, tensile, pilling, abrasion and dimensional properties of the
fabrics following the standard procedures laid down by BIS and ASTM. The data
obtained was compiled, tabulated and statistically analyzed using frequency and
percentages. Statistical tools such as ANOVA (Two factorial, CRD) was selected for
assessment of significant differences between samples and treatments. Where as
correlation was used for quantifying the dependency of various characteristics on one
another and percentages were calculated for the subjective evaluation.
The yarn count of the samples was high in control fabrics and it had decreased in
the pretreated fabrics. Yarn count had good correlation with fabric weight, thickness,
stiffness and thermal conductivity. No change was observed in the fabric count in both
control and pretreated samples. Fabric weight was very high in control fabrics and it had
decreased in the pretreated samples. It has positive correlation with fabric thickness,
stiffness, drape co-efficient and thermal conductivity.
The thickness and stiffness was decreased and crease recovery increased for the
pretreated fabrics. Thickness had good correlation with stiffness and thermal
conductivity. Good correlation was observed with drape co-efficient for stiffness. Crease
recovery enumerates negative correlation with stiffness, thickness, drape co-efficient and
thermal conductivity. The drape co-efficient of the fabric was decreased which implied
that the drape of the fabric was increased for pretreated fabrics and very high correlation
has emerged with fabric weight, stiffness and thermal conductivity. Considerable
changes were noticed in the comfort properties, but water repellency remained the same.
Tensile properties of the fabrics were decreased due to the treatment confirming the
changes in the molecular structure and arrangement it had negative correlation with
thickness of the fabric. Pilling has no change in both the fabrics. The Abrasion resistance
was decreased in the pretreated fabrics and emerged positive correlation with thickness
and air permeability. No change was observed in the dimensional stability of the banana
fabrics and its blends. Among all the pretreated fabrics sample B (60:40) banana, jute
showed better improvement in textile properties than other samples with this treatment.
The subjective evaluation on the aesthetic qualities of fabrics reveled that
pretreated fabrics received high ranking than the control fabrics. The cost of the finishing
was economically viable for adoption at the commercial level. Sample B (60:40) bananajute
blend was found to be better in all its characteristics than other two blend samples.
From the above data it is clearly evident that the enzyme pretreated samples of
banana and banana blended textiles showed improvement in several properties such as
surface smoothness, handle, comfort, pilling and abrasion properties, which inturn
enhanced their suitability in the area of furnishings.
