Abstract
In this work, cognitive behaviour and electroencephalography (EEG) of 16 subjects applied colour matching and contrast
colour matching to silk fabrics had been measured. The results showed that, the exogenous components P1 (100 ms)
and P2 (200 ms) were mainly produced in the frontal, temporal, apical, and occipital regions, while the endogenous
component P3 (300 ms) was mainly produced in the front-top area, the front-central area, the central-top area, and the
top-pillow area. Regarding P1, the information transmission speed was faster than contrasting colours with matching
process. Regarding P2, external and internal factors and their interactions significantly affected amplitude, whereas only
interactions affected latency, and the interaction was stronger with colour matching. Regarding P3, colour matching type,
involved brain area, and interactions had no significant effect on amplitude and latency. The information processing of
same colour system in brain has shorter information processing time and faster information transmission. That indicated
the EEG technology could provide objective visual cognitive aesthetic rules for silk fabric colour matching, and provide
reference value for fabric manufacturers to timely understand consumers’ preference for fabric colour categories.

Abstract
Clothing comfort is very important feature which is considered as a result of different process of heat exchange between
human body, clothing and environment. The purpose of this paper is to analyse the impact of clothing insulation on the
heat transfer. The measurements were carried out on commercially 1x1 RIB knitted fabrics used for the production of
next-to-skin shirts. The one group of samples are made from 100% cotton yarn and another with 96% cotton and 4%
lycra. It is noticed that knitted material composition affected the change in heat resistance. Also, this paper presents and
verifies the correlation between the measured values of thermal resistance (Rct) and the knitwear thickness (dpl), the
covering factor (K), the porosity of the twists (ε) and the surface coefficient (δp). Based on these results, a mathematical
model for calculating thermal resistance is proposed. Comparing the results obtained with the proposed equation
and the measured results, we can see that the deviations are minimal. The highest deviation for sample C4 is 0.05%,
while the largest deviation for sample CL4 is 4.6%.

Abstract
Sanitary napkins are technical textile products which are used by women. They are designed as layered structures to
fulfil several end–use properties at the same time. One of the most important properties of sanitary napkins is absorption
property and this is widely studied in the literature. On the other hand, formability and sensorial comfort of sanitary
napkins are of great importance but they are ignored during scientific researches. During daily life, women sit or sleep
for certain time intervals and their sanitary napkins are exposed to compressional forces. If the sanitary napkin will
squeeze and not recover, this can result with poor sensorial comfort and low formability. Also, wetting of sanitary napkins
during usage can worsen the compressional properties. Therefore in this study, effect of wetting and
compression/recovering time on the compressional behaviours of sanitary napkins was evaluated. Study was focused
on separate sanitary napkin layers in order to detect the most problematic layers. Two compression times and four
recovering times were applied to samples for compression tests. Also, sanitary napkin layers were characterised by
scanning electron microscopy, unit mass, thickness and bending measurements. According to results, top sheet layer
was the most compressible layer in dry and wet states. This is expected to give a soft and resilience sense to the
sanitary napkin. Absorbent layer was responsible for low compressibility of sanitary napkins under different
compression/recovering times. Bending rigidity of absorbent layer was the highest in dry state but it exhibited a dramatic
decrement after wetting.

Abstract
The aim of this paper was to analyse the impact of service marketing mix (promotion, price, place, product, people,
process, physical evidence and after sale service) on customer retention towards clothing store brands in China. Based
on the analysis of past literature, it appeared that there were only few studies examining the empirical relation between
the two constructs, particularly in the clothing sector in China. A comprehensive survey approach was used to collect
data from a total of 385 customers visiting clothing stores in the middle part of China (Hubei). SPSS and PLS were used
to analyse the obtained data. The findings showed that there were significant positive effects on customer retention in
all dimensions of the service marketing mix. Finally, the findings suggested that after-sales service plays an important
role in impacting the retention of customers. The contribution of this research was supporting the significance
relationship of the marketing mix elements in influencing the retention of customers in the clothing industry with empirical
data from China.

Abstract
Electromyography (EMG) test, the recording of electrical activity in muscle, is a main tool usually used to evaluate the
muscle’s activation. This study aims to discuss and analyse the effect of woven compression bandage (WCB) on
muscles’ activation. Flexor Carpi (FC), Soleus (SO), and Medial Gastrocnemius (MG) muscles were selected to
represent the wrist, ankle, and mid-calf muscles respectively, which were then evaluated by EMG electrical voltage test
with and without wearing WCB. The standardized activities used to test the FC muscle were flexion-extension and
squeezing a soft roll. While the protocol activities for MG and SO muscles were flexion-extension and walking actions.
Wearing WCB significantly decreased the muscle’s activation and was associated with higher median frequency for both
SO and MG muscles during the tested activities. The EMG signals were analysed and filtered using MegaWin and
MATLAB software. Root mean square (RMS) values confirmed that wearing WCB could improve the performance of FC,
SO, and MG muscles and might reduce the muscle’s fatigue during the selected activities.

Abstract
Denim fabrics became a preferred product by many people, because of especially being a symbol of comfort. In this
study, the aesthetic and physical design of denim fabrics were carried out. It was aimed to compare the surface designs
and structural parameters of denim fabrics obtained by weaving and laser technologies. Besides the design steps of
weaving and laser technologies were explained and compared. Twelve denim fabrics having different surface designs
were obtained with the intersection of indigo dyed warp and non-dyed weft yarns based on the theme of “contrast” by
using derivatives of twill weave. Besides, these surface patterns were applied to classical denim fabrics by laser
technology. The surface properties of denim fabrics produced by weaving technology were different for each surface
designs because of different floatings. However, weaving is a time-consuming method and the design steps are more
complicated. On the other hand, surface patterns of fabrics obtained by laser technology were found similar to woven
ones and it had advantages as having greater design capacity, being a simpler, faster and eco-friendly method.

Abstract
Currently, the issues related to environmental pollution with plastics are a major concern. Agriculture is a vital area for
human existence, but it generates large amounts of plastic waste. These result from agricultural practices that use
systems and support materials which help facilitate the work of farmers and offer a better yield of production and quality
of crops, in relation to the smaller areas of agricultural land. An alternative can be the use of sustainable textiles that
can bring multiple benefits to the agricultural sector, including: pollution reduction, biodegradation potential, reduced
consumption of agricultural inputs like pesticides, herbicides, fertilizers and water, high retention potential for water and
good ventilation, increased productivity and quality for the agricultural crops, etc.
First of all, this paper discusses the potential use of bio-based and eco-friendly polymers, such as polylactic acid (PLA),
in the form of fibres for the production of non-woven textile structures that can be used as a support element in
agricultural practices and for the replacement of conventional plastics obtained from oil resources. Secondly, considering
the advantage of the biodegradation property of this material, the durability and the influence of the location depth in a
degrading natural environment such as soil, were the target of experiments to highlight the positive aspects of polylactic
acid use in the context of the circular economy. To demonstrate the proposed objectives, different physico-mechanical
analyses were performed to determine the morphological characteristics of the fibres, the tensile strength, the material
thickness and the possible loss of mass due to microbial activity.

Abstract
Agglomeration is an important characteristic in China’s textile industry development. But regional textile industry is
seriously unbalanced, only eastern location entropy (LQ) is greater than 1 and is the highest of all, followed by the
central, western and north-eastern regions. Total factor productivity (TFP) is an important indicator to measure the
economic growth efficiency. The average annual growth rate (AAGR) of eastern textile industry TFP is the least and
central TFP growth rate is the fastest. In order to investigate the relationship between agglomeration and TFP of China’s
textile industry, especially at region level, this paper applies panel model to study how agglomeration influences TFP
during 2005–2018. The results show that increasing agglomeration degree restrains the TFP growth of China’s textile
industry. The coefficients of LQ on textile industry in China and four regions are all negative. There exists crowded effect
in eastern textile industry. It has not formed the significant agglomeration effect in western and north-eastern textile
industry for very low agglomeration degree. So it implies that eastern textile industry can accelerate the implementation
of industrial transfer and structural adjustment to lower agglomeration and maintain sustained profitability of textile
enterprises. Western textile industry can strengthen agglomeration by undertaking industrial transfer from eastern region
to form agglomeration effect to promote TFP growth.

Abstract
This paper depicts the early phase in the research development for an integrated UAV (Unmanned Aerial Vehicle)
support system tailored for emergency response actions and remote sensing. The support system is envisioned as an
integrated Unmanned Aerial System (UAS) system that consists of one or more ultralight multifunctional aerial units with
a configuration that can be adapted to the nature of the intervention: monitoring, mapping, observation, logistics etc.
These aerial units comprise of para-motor type UAVs that use textile paraglider wings of a special design.
The overall development and theoretical design aspects that are involved in this research is subject of change been part
of an ongoing research study. Starting from wing airfoil and material selection, a design phase is under development for
a single sail paraglider wing that can meet the operational demands for the envisioned system. The wing is designed
mainly to have an easy handling, predictable deployment at all times and good aerodynamic characteristics. The paper
tackles in particular the stretch effect on the wing and the influence on these aerodynamic characteristics as well as
means of minimizing the adverse effects.

Abstract
The clothing and fashion industry is known as a wasteful industry. Despite its target, producing fashionable and beautiful
items to fulfil the needs of different consumer categories consumes a considerable quantity of raw materials, energy,
water, labour force, etc. Every year, natural resources become more limited, hard to find and expensive; in these terms,
the producers are forced to find either alternative solutions to replace as much as they can the needed primary raw
materials or to try to maximise their use (which means to reduce the quantity of waste) or to use the waste to produce
other things. The consumption of raw materials is determined during the development stage of the new model: the
designer analyses the sketch of the selected model, then establishes and applies the needed steps to design the model
pieces, creates the 3D virtual or supervises the manufacturing process of the physical prototype to verify the design
solution, applies changes after analysing the prototype if it is necessary, obtains the production patterns and then he/she
is doing the markers to determine the consumption of raw materials for one item and the whole order. Garment models
with creases, pleats or folds are the most challenging ones because the designer has to have the ability to understand
and to evaluate the shadows or the number of grouped lines of the model into values of distances or angles, to be used
to change the element surface for their realisation. In these cases, it is essential to balance what the model requires and
the needed amount of raw materials to produce it. This paper proposes some variants of how to resize the surfaces of
the elements for designing creases but with an optimal raw material consumption level. The results are based on the
analysis of different men jacket models’, with straight silhouette and creases between the hemline and its hem band.

Abstract
This study presents the comparative analysis of production, characterization and absorption properties of
Polyvinylpyrrolidone (PVP) and Polyacrylic acid (PAA) nanofibres. Firstly, optimization studies about polymer (PVP and
PAA), superabsorbent additive (waterlock)(WL) and crosslinker agent (sodium persulfate and glutaraldehyde)
concentrations were achieved. Then solution properties such as conductivity, surface tension and viscosity were
determined. Electrospinning was carried out under the optimum process parameters (voltage, distance between the
electrodes, solution feed rate etc.) to obtain superabsorbent nanofibrous surfaces. Surface and fibre morphologies were
analysed with Scanning Electron Microscopy (SEM) and thickness of nanoweb and weight in grams of nanofibres were
also measured. Lastly, optimized PVP and PAA nanofibres were compared in terms of absorption properties with water
and synthetic urine with various times from 5 to 86400 seconds. According to the results, generally fine, smooth and
uniform nanofibres were obtained. It was observed that the solution viscosity, conductivity, and average fibre diameter
increase with waterlock (WL) and cross-linker additions while surface tension was not change. In addition, PAA
nanofibres’ absorption capacity with water and synthetic urine was higher than PVP nanofibres, while PVP nanofibres’
absorption rate is higher. It is possible to say that electrospun nanofibrous surfaces that are ultra-thin, light, porous and
with high specific surface area to volume ratio are promising for new superabsorbent materials.
