Abstract
This study presents a strategy to obtain textile materials with hydrophobic/oleophobic effect by applying hybrid coatings
based on a mixture of flower-like ZnO nanoparticles and organically modified SiO2 nanoparticles (ORMOSIL). The
obtained dispersions based on both types of nanoparticles are stable, with unimodal distribution of smaller quasi
spherical shape and average size of 158 nm for SiO2 nanoparticles and respectively, with bimodal distribution with a
broad distribution of particle size and average size of 144 nm and 435 nm for ZnO flower-like nanoparticles. The
ZnO/SiO2 NPs based dispersions were then applied on 100% cotton fabrics on a laboratory scale by padding method
in two successive phases. The functionalized cotton fabrics were evaluated in terms of surface morphology changes,
whiteness degree and water and oils repellent properties. The developed textile materials exhibited a low wetting
capacity, with high values of water absorption time (> 15 minutes) and a water-repellent degree of 75 (AATCC photo -
graphic scale) and 2.5 respectively (ISO scale) showing an acceptable hydrophobic effect. The functionalization
treatment based on mixture of ZnO/SiO2 nanoparticles led to obtaining an efficient cotton substrate for the rejection and
protection against the oily substances which exhibit an oil repellency degree of 6. Also, the functionalization treatments
did not significantly change the surface morphology of the fibres, suggesting that the bulk properties of the cotton fibres
remained undamaged.

Abstract
Turkish traditional Buldan weavings are known as special fabrics in terms of providing comfortable clothes which are
known to be natural and healthy in Denizli, Turkey. The research presented in this paper assesses the effects of different
fabric structural parameters of Buldan fabrics on comfort properties such as thermal resistance, thermal absorptivity,
water vapour permeability and air permeability. Five different Buldan fabrics woven with different fabric structural
parameters were produced. According to test results, cotton/Tencel Buldan fabrics indicated similar comfort properties
with the 100% cotton Buldan fabric properties. Additionally, the lowest thermal absorptivity was observed from 100%
cotton Buldan fabrics which give the warmth feeling among the evaluated samples.

Abstract
The field of mechatronic/robotic wearable exoskeletons, specifically those designated for assistance/rehabilitation in
severe neuro-/locomotor disabling conditions in the lower limbs, is considered to have a great potential for radically
changing the harsh condition of wheelchairs users, by restoring their defining human traits: bipedal, vertical, stance and
gait. But even the most advanced such complex devices, are not yet effectively able to largely replace the wheelchairs.
Therefore, until the overall complete wheelchairs’ substitutes, will meet, in this purpose, all the necessary related
requirements, we have determined, and accordingly, designed – from a double perspective: of professionals and of (a)
consumer – a series of necessary and rather accessible/feasible, consistent: mechanical and electro-mechanical
improvements, to the current common type of wheelchairs, in order to improve the global functioning, autonomy and
consequently, the quality of life in the needing people, with severe mobility restraints. These, for now, narratively
innovative concepts and specifically designed, practical/technological-constructive solutions, target 10 main kinds of
beneficial outcomes, i.e. a decalogue and their derivatives to be expected (most of them previously imagined by us but
not completely designed until now, two of them already achieved but which need updating and other four entirely new),
that could result in an “all-in-one” product paradigm which, to our knowledge, is not available at present. This model of
wheelchair we propose is, at the same time, modular, so a certain consumer can purchase/ be offered only his/her own
case-specific needed optimization components of it.

Abstract
The fabrics used to manufacture parachutes and paragliders must have several specific characteristics: the mass of
fabric per unit of surface must be low while the other physical-mechanical characteristics (the axial breaking strength
load, the relative and absolute elongation, the tear resistance of the fabric and the assemblies, air permeability) must
have high values. The paper deals with the analysis of qualitative aspects of several parachute fabrics that are used as
a baseline in the development of a novel fabric. The results of experiments have materialized in statistical data, diagrams
and graphs and their interpretation leads to the determination of the fabric variant that best meets the requirements of
the destination. The destination is a patent pending inflatable wing design that utilizes a single skin construction and
solid reinforcements in the sewing for shape stability. It is worth noting that the experimental results were compared with
values indicated in specific international testing norms.

Abstract
This research paper examines the holiday effects presence on the Bombay Stock Exchange (BSE), which is a major
Indian stock exchange. Textile and clothing industry in India is one of the most important producers in the world, but also
the second exporter of textile and apparels globally. The empirical analysis investigates the impact of holiday effect on
the development of textile and clothing industry in India. The holiday effect is one of the most important calendar
anomalies identified in the financial markets. The methodological approach includes the non-parametric Mann-Whitney
U-test used to test the equality of means for different sub-sets. The findings revealed that the mean returns for
pre-holiday and post holidays were greater compared to that of remaining days, but the empirical results showed that
they were not statistically significant for selected stocks of BSE based on daily stock returns data for Ruby Mills and
Mafatlal Industries.

Abstract
This work presents several aspects of the multivariate regression importance in the analysis of the parameters (dependent
and independent variables), which characterize the 3D composite materials with electroconductive properties. The
experimental part was developed by using fabrics from 100% cotton, 100% polyamide, and 100% polypropylene fabrics
to obtain the electroconductive and electromagnetic properties based on classical technologies and 3D digital printing
advanced technology. The fabric was printed with paste containing zinc, copper, nickel, iron oxide II, III, silver, and
Graphite microparticles content. Initially, the fabric has coated using the standard technologies implemented by padding
(Flame Retardants), scraping, and 3D printing advanced technology for submission of the ESD filaments. For flame
retardancy properties, the fabric has been impregnated in a solution of 50% Aflamit and dried at a temperature of 120°C
for 3 minutes.

Abstract
Textile’s primary hand (HV) and total hand values (THV) are very important parameters and are used to identify the
quality of clothing comfort. This paper aims to predict the HV and THV of the fabrics finished with functional polymers
by applying Kawabata’s translation equations. The mechanical properties were achieved using Kawabata’s fabric
evaluation system (KES-F) and the inference/interpretation was drawn. Then, HV and THV predictions were performed
by applying Kawabata’s translation equations of the KN-101 and KN-301 series. The KES-F result confirmed that it is
possible to observe the operative finishing effect on the mechanical properties of fabrics. The prediction results show
that the total quality comfort of the functional fabrics could able be estimated by the equation developed by Kawabata;
the calculated errors (~0.66) were within the range of the standard deviations (~0.78) of the samples between the
predicted and ranked THV. The experimental and the calculated primary hand values showed strong correlation
coefficients up to ~0.98 which is significant at 0.001 confidence levels. As actual functional fabrics with various surface
properties were provided to estimate their tactile comfort via the equations, the result verified that the equation is reliable
for the tactile comfort evaluation and grading.

Abstract
The use of natural dyes for textiles has attained attention due to their ecology, minimum impact on the environment and
pollution. Therefore the objective of this study is to dye Lyocell fabric with natural dye extracted from orange peel for
comparative analysis of colour efficiencies (K/S), CIE L*a*b* values and the colour fastness properties. The mordants
applied were ferrous (II) sulphate and copper (II) sulphate. For the extraction of the dye, the aqueous extraction method
was used. The pre-mordanting method was used and the dyeing effect on Lyocell fabric was analyzed at concentrations
of 2% and 4%. It was observed that the mordant type employed had an influence on the colour efficiency and the colour
coordinates of fabric dyed with Citrus aurantium dye. The colour efficiency (K/S: 4) and colour fastness to washing, light,
rubbing and perspiration in all the dyed samples were better and excellent (grade 4–5) at 4% concentration. In overall
results, the pre-mordanting method at 4% concentration gives the best results of colour efficiency and colour fastness
properties. The performance analysis of colour fastness was also statistically significant at the 0.05 level.

Abstract
In a sustainable society, the integration into the activity of entities of the actions from the sphere of social responsibility
becomes more and more evident.
The study analyzes the textile industry in Romania in terms of social responsibility, the involvement of companies in this
industry in asserting the values of this level. Thus, a quantitative marketing research is carried out at the level of the
population in Romania, a piece of research which is aimed at identifying the opinions and attitudes of the citizens
regarding the social responsibility adopted by the Romanian companies, with emphasis on the companies in the textile
industry. In this research, particular attention was given to the comprehension of the reality of the aspects in which
consumers perceive the requirements of social responsibility and of the way in which they function in practice. The
results of this research can be used by the companies in the textile industry as well as by all the companies interested
in this aspect in order to improve the quality of the services and of their implications in the social life and in order to
respond to the needs of the citizens as well as possible.

Abstract
The paper dealt with the existence of causality in Granger’s sense between competitiveness and market share, and vice
versa, on emerging markets so as to answer the question whether it is possible to forecast the movement of the market
share of an enterprise based on the data about the movement of the competitiveness of that enterprise. The research
study was carried out on 96 textile companies from Serbia, Montenegro, and Bosnia and Herzegovina. The results of
research have shown that relationship between competitiveness and market share is generally weak and in many
industrial sectors it is nonexistent. In other words, the research results reveal that the existence of causality in Granger’s
sense between competitiveness and market share on the selected emerging markets depends on the branch of textile
industry.

Abstract
Customized clothing manufacturing is a clothing manufacturing method realized and performed in collaboration between
the manufacturer and the customer. In this manufacturing method, the customer is offered a basic piece of clothing and
various options (fabric, model, color, style, accessories, printing on clothing, etc.) so that the customer can modify the
clothing and design the most suitable garment. Thanks to this manufacturing method, the customer has the opportunity
to purchase the most appropriate personalized clothing while, at the same time, the manufacturer achieves a high profit
margin by making a customized product. Customized clothing production is an important method in the industry because
it increases both the profit margin of the enterprises and the level of customer satisfaction. Although it is not yet a very
common method, it is expected that it will become widespread in the future with technological developments. Within the
framework of this study, we focused on online customized T-shirt manufacturing. The study was carried out in three
stages. In the first stage, the design options that young consumers prefer and/or need for online customized T-shirt
design were determined. In the second stage, websites that perform the manufacturing of customized T-shirt that are
available online in Turkey were determined. In the third stage, online T-shirt design options determined in the first stage
were presented to the customers by the websites determined during the second stage. According to the assessment,
customized T-shirt design websites active in Turkey were found to be adequate in terms of the “design with respect to
body sizes” option. In addition, some design options that online personalized T-shirt design websites intend to offer
change according to the gender and education of young consumers.

Abstract
In this paper, the effect of degumming processes on the physical performance, surface properties and colour
coordinates of silk fabrics at high temperature and enzymatically, which was developed as an alternative to conventional
method, has been investigated. Degummed silk fabrics were compared in terms of weight loss, bending length, tear and
breaking strength, surface roughness and friction coefficient. After these tests, acid dyeing was performed to observe
different degumming methods effect on dyeing behaviour of degummed silk fabric. The colour coordinates were
evaluated by L*, a*, b*, C*, h0, K/S, and ΔE* values. The results revealed that despite insignificant differences between
conventional and alternative methods in terms of physical performance and surface properties, the conventional method
gave slightly better results than the others. There were no significant differences in colour depth between the two
processes. These reasons showed that the alternative method could be used instead of the traditional method and a
more sustainable process has been designed.

Abstract
The recent studies report an increase in the percentage of newborns diagnosed with cerebral palsy (CP) in industrialized
countries due to the increased survival rate of infants with low birth weight. The assessment of the upper limb motor
function and manual skills are important steps in achieving a suitable multi-modal therapeutical plan, aiming at gaining
functional independence and early integration into society. The study seeks to identify how the motor deficiency present
at the level of the upper limbs influences the manual skills of CP patients reflected in daily activities (Activities of Daily
Living – ADL) and using medical textiles. 35 patients diagnosed with CP were assessed during hospitalization using, for
the comparative reflection of ADL dexterity assessment results, at the same patient, quantified, the Action Research Arm
Test (ARAT) scale and ABILHAND-Kids. A highly significant correlation was found, the ABILHAND-Kids score being
moderately correlated with the ARAT score, obtained in the upper limb with more deficient functionality (0.578) and
respec tively with better functionality (0.570). The assessment of the child suffering of CP, using the ABILHAND-Kids
questionnaire and the ARAT test provides to the rehabilitation team useful information, with the benefit of complemen -
tarity for the elaboration, based on several correlated elements, of the case management plan and methodology. Proper
treatment, instituted early, can have a favorable influence on the social integration of these people. A remarkable
contribu tion has been made by the textile domain which, through its sustained concerns regarding the research and
development of biotechnologies and biomaterials, proves its permanent concern in supporting and integrating these
people.

Abstract
The purpose of the present study was to investigate the heat transfer through a system of two consecutive textile layers
with woven macrostructures by numerical simulation, using FLUENT CFD software package. A novel approach for
modelling of the textile structure was applied, based on jet systems. The heat transfer through the systems of layers was
studied for indoor conditions, simulating skin and indoor air temperature, as well as the effect of the convective cross
flow around the human body. The results of the study showed that the heat transfer through a system of two layers is
strongly influenced by the porosity and thickness of the fabrics, as well as their arrangement in the systems as an
insulating barrier between the body and the environment.

Abstract
This paper proposes an optimization model for the Assembly Line Balancing Problem (ALBP) in order to improve the
work group choice in clothing industry. Traditionally, ALBP deals with several objectives like minimization of workstations
number, minimization of cycle time, maximization of workload smoothness, and maximization of work relatedness…but
neglect operators’ performance. As the worker competence is crucial to both product quality and productivity, an
approach is proposed to balance production line through optimal operators’ assignment with the consideration of their
skill levels. Based on two criteria, which are the Quality Index “QI” and the Activity “A”, each worker was evaluated in
each executed operation. From these individual criteria, global indicators of the work group selected were proposed.
Applying the Weighted Sum Model (WSM) a more general indicator which is the global Competence Index “CIg” was
presented. Using simple linear regression model, the global competence was modelled. Thereafter, the model was
validated and justified. The resulting performance indicator allowed predicting the global competence level, comparing
different balancing proposals and making an optimal choice. So, a new objective function to maximize can be used in
ALBP resolution in order to optimize the selected group capability.
