Abstract
This  paper  presents  aspects  concerning  the  life  cycle  assessment  of  the  electroconductive  textile  functionalized  by advanced RF plasma technology based on argon and oxygen gases and deposition of the metallic micro/nanoparticles. In order to obtain the textiles with electroconductive properties, the preliminary plan consisted functionalization of the textiles by using RF plasma technology based on argon and oxygen gases and processes for micro/nanoparticles deposition suchas foulard, direct printing, and thin film position. It was analyzed the life-cycle inventory (LCI) and was provided the studyfor life-cycle assessment (LCA) using SimaPro software and Eco-indicator 99. In order to obtain the LCI, we used to input and output technical data, from the plasma process, and the SimaPro software for generating the LCI and LCA. The input data about raw material, energy, chemical substances, have been collected by direct measurements on machinery, device log, and specifications of the equipment (technical books) and processes. The output data was obtained using SimaProsoftware  connected  to  internet-specific  databases.  The  purpose  of  our  research  has  been  to  study  the  life  cycle assessment  of  the  electroconductive  textiles  functionalized  by  RF  plasma  technology  in  comparison  with  classical functionalization treatments.

 Abstract 
This  research  aims  to  analyze  certain  effects  of  yarn  characteristics  such  as:  cotton  type,  yarn  quality,  yarn  spinning technique, yarn twist and linear density and yarn finish on coefficient of friction of yarn by using Taguchi approach. For evaluation of levels and response factors, 72 experiments are performed by using L36 orthogonal design twice for Taguchi approach. The results show that yarns comprising of finer fibers, combed, waxed, Rotor spun, optimum twist and low linear density have lowest coefficient of friction of yarn, which ultimately improves subsequent textile processes and improve product qualities.

 Abstract 
The use of recycled materials has gained massive importance in textile sector as well as in other sectors as the effects of reduction of natural sources are felt all over the world. In this study, it was aimed to analyse the effects of recycled cotton usage on properties of OE-rotor spun yarns and knitted fabrics produced from these yarns. For this purpose, OE-rotoryarns were produced at different proportion levels of virgin cotton and waste cotton that derived from blowroom 25%, 50%,75%,100%, respectively. For better assessment, properties of OE-rotor yarns that contain waste cotton were compared with 100% virgin cotton OE rotor yarn. Physical, structural and mechanical properties such as unevenness, imperfections,hairiness,  breaking  force,  elongation,  yarn-to-yarn  friction,  yarn-to-metal  friction  and  yarn-to-ceramic  friction  were measured by Uster Tester 4 SX, Uster Zweigle Hairiness Tester 5, Uster Tensorapid 3 and CTT by Lawson Hemphill. Atthe second part of the study, single-jersey knitted fabrics were produced from OE-rotor spun yarns. Effects of waste cotton proportion on knitted fabric properties such as pilling, abrasion resistance, bursting strength and air permeability were also evaluated.  Results  showed  that,  the  use  of  up  to  75%  per  cent  of  waste  cotton  blended  yarns  show  no  statistically significant differences on yarn and fabric properties.

 Abstract 
This  paper  presents  several  aspects  concerning  the  life  cycle  assessment  (LCA)  for  100%  cotton  fabric  treated  with different types of Fluor compounds using RF plasma technology and foulard technology, in order to obtain the hydrophobic effect. To highlight the effects obtained by RF (radio frequency) plasma technology was conducted in parallel a study about hydrophobic effect obtained using a dispersion of fluorine compound (NUVA TTC) on foulard. The conclusions of the study were that if we use the plasma treatment for hydrophobic effect then this would influence the environment negatively by warming generated by gases and power consumption, when using the foulard method and chemical substances already established, the impact would consist of increasing the consumption of fossil flues, respiratory in organics, and climate change.  We  analyzed  the  life-cycle  inventory  (LCI)  and  life-cycle  assessment  (LCA)  using  SimaPro  software  andEco-indicator 99. For obtaining the LCI, we used to input and output technical data, from the plasma / foulard process, and the SimaPro software for generating the LCA based on these data. The input data about raw material, energy, chemical substances, have been collected by direct measurements on machinery, device logs and specifications of the equipment(technical books) and processes. The output data (waste energy and chemicals) were obtained using statistics, internet databases,  and  SimaPro  software.  The  objective  of  our  scientific  initiative  has  been  to  study  the  sustainability  of  the RF plasma technology used for hydrophobization, and we obtained that plasma technology used for hydrophobic effect isless eco-friendly than foulard technology for a functional unit of 1 kg treated material.

 Abstract 
Using prosthesis to replace weaken tissues or fascia in pelvic is accepted by more people in present medicine field. PDO is also considered to be an ideal degradable material such as PP, which was the most popular used type in medical area. The paper prepared macro-porous structure PDO meshes using an armor plate model of square-pore structure and raw material of PDO monofilaments. Fabrication parameters including monofilament diameter, pore size, pore shape were discussed based on a suitable mechanical properties of PDO meshes. The optimal fabrication processes were obtained after then. The results revealed that PDO mono filaments of 0.23 mm diameter could make mesh to own moderate weight,thickness  and  tensile  strength,  as  well  as  the  largest  suture  pulling  out  force.  Square-pore  shape  strengthened  mesh tensile force, maintaining larger suture pulling out force especially compared to that of rhombus-pore shape. As for poresize,  PDO  mesh  with  5  mm  pores  had  larger  strength,  also  satisfying  requirement  of  mesh’s  lightweight.  In  vitro degradation  of  PDO  mesh  was  measured  using  3  different  diameter  monofilaments.  All  samples  were  significantly degraded  only  after  10  weeks,  with  weight  loss  rate  reaching  to  about  30%  after  16  weeks.  Finally,  PDO  mesh  was assessed to have an obvious lightweight advantage, but low strength risk by comparison to several commercial mesh products.

 Abstract 
The aim of this study was to investigate the influence of new hybrid composites of TiO2 or SiO2 nanoparticles with poly(2,2’-bithiophene) on 50% cotton/50% polyester fabric and sheep skin leather surface properties. The dispersion-based newlymade  nanocomposites  were  analyzed  to  determine  conductivity,  particle  size,  polydispersity  and  Zeta  potential.  The finished textile and leather materials were characterized in terms of functionalization treatments performance by: surface resistivity, water contact behaviour, physical-mechanical characteristics and photocatalytic properties. SEM analysis wasused to investigate the distribution of nanoparticles on the textile and leather materials surface. Textile materials treatedwith SiO2/poly(2,2’-bithiophene) nanocomposite with concentration 98 wt% nanoparticles of SiO2 and leather treated withpoly  SiO2/poly(2,2’-bithiophene)  nanocomposite  with  concentration  of  95  wt%  nanoparticles  of  SiO2 showed  lower resistivity values, confirming the conductive properties of silica. The higher photodegradation efficiency of functionalized materials  has  been  obtained  for  textile  material  treated  with  poly  TiO2/(2,2’-bithiophene)with  concentration  of  95  wt% nanoparticles  of  TiO2 and  for  leather  material  treated  with  TiO2/poly(2,2’-bithiophene) with  concentration  of  98  wt% nanoparticles of TiO2, respectively.

 Abstract 
Reconstructive surgery of the abdominal and thoracic wall frequently utilizes various materials in order to repair large defects.  Polypropylene  meshes  are  an  example.  In  nasal  reconstructive  surgery  they  are  rarely  used  for  cartilage restoration. The purpose of this paper is to demonstrate the utility of the collagen-coated polypropylene meshes in nasal reconstructive surgery, as they are easy-to-use materials, with reduced incidence of foreign body reactions and with a very small price compared with other compounds. We  conducted  a  literature  review  on  the  usage  of  the  collagen-coated  polypropylene  meshes  which  also  includes  acomparison with other types of materials applied for nasal cartilage reconstruction. Moreover, we performed a retrospec -tive study, on the patients hospitalized in the Plastic Surgery Department of the Clinical Emergency Hospital, Bucharest.  The best option and in the same time the gold standard for nasal cartilage reconstruction is considered to be autologouscartilage transplantation. In our clinic we observed good results when autologous septalor auricular cartilage grafts wereused. Polypropylene is seldom used in nasal reconstructive surgery, having been conducted so far, a limited number of studies related to benefits and disadvantages of this type of material in the accomplishment of the medical devices used as a nasal implant.  Polypropylene  meshes  are  largely  used  in  abdominal  wall  reconstruction  and  in  the  surgery  for  pelvic  organprolapse. In this surgical field, collagen-coated polypropylene meshes are also used, but future studies will demonstrate if they are effective enough in the nasal reconstructive surgery as well.

 Abstract 
Four colour difference formulae [CIELAB (1976), CMC (2:1), CIE94 (2:1:1) and CIEDE2000 (2:1:1)] were assessed in CIELAB colour space for regular changes in colour coordinates. L*, a* and b* coordinates were changed regularly both as increasing and decreasing steps in different lightness and hue regions of the colour space. The dependence and consistency of the four formulae were researched depending on regular and constant colour coordinate changes. The aim of the empirical study was to determine if there could be a possibility of using different colour difference formulae indifferent hue regions of CIELAB colour space; in the region of bulk that each formula would give the best fitting and themost reliable results. The empirical study was carried out by using a special software which was prepared for the purpose. The results showed that CIELAB and CIE94 gave corresponding results with each other in the computing ranges. All the formulae showed different computing characteristics in the computation ranges. CMC formula gave the highest colour differences when computing near the grey point. It was concluded that CIEDE2000 formula suited itself the best accordingto the changes in computing steps. A more complicated software would be necessary to determine the sensitivity of the formulae by which the computing would be performed by changing all the coordinates (L*, a* and b*) at the same time.

 Abstract 
Coating technology is an increasingly popular method for creating special designs and getting different appearance to denim fabrics. Depending on the expected properties from denim fabrics, the process parameters of coating can be changed. It is important issue how process parameters affect the comfort characteristics of denim fabrics. The present study is aimed at optimizing the various coating process parameters for the air permeability properties of denim fabrics by using Taguchi method. The parameters selected for optimization are squeeze pressure, viscosity of coating fluid, fabric passing speed, drying temperature and weft density of fabrics. An L27 (35) orthogonal design was chosen as experimental plan. In the evaluations with Taguchi Method, analyses of the signal to noise ratio (S/N) and variance (ANOVA) were used. The results show that weft density and viscosity have significant influence on the air permeability properties of coated denim fabrics.

 Abstract 
Scholars have supported the idea that interorganizational knowledge networks are a key factor for firms’ innovation inclusters. Yet, existing empirical evidence suggests that, while networks can enhance firms’ innovative performance, not all network linkages influence to the same extent. On this basis, this paper aims to explore in a Spanish textile cluster how the involvement in business and technical knowledge networks influences textile firms’ innovation. The results reveal the influence of the firms’ connectedness to the cluster knowledge network on their innovative results, although only in the case of the technical knowledge network. These findings provide relevant insights for an efficient management of territorial networks at the firm level and for a better definition of textile clusters’ industrial policies.

 Abstract 
Assessing the financial performance of a firm or sector is an important issue for managers, investors and business partners. The basic information used for financial performance assessment is found in financial statements. The accuracy of the method used for this evaluation depends on the accuracy of financial statements provided by firms that reflect the activity developed. In this paper we propose an aggregated index for evaluation the financial performance, based on 11 selected financial rates. The method was applied on a sample of 82 medium-sized companies acting in the Romanian textile sector. Textile industry is an industry with tradition and an important sector of Romanian economy, both in terms of the contribution to gross domestic product and export growth; it has undergone in the last 20 years a difficult period of transformation and adaptation to a changing market, but has a competitive advantage reported to the European one, mainly due to low-cost labour force. The research results show the hierarchy of the textile firms after financial performance score, 42.68% of firms having a score above sector average. The results are useful, especially to managers, by improving decision making of business funding and development, forecasting the future financial performance, selecting business partners, making profitable investments, and to financial analysts in fulfilment of business objectives.

 Abstract 
Softeners are of great importance in textile processing. The aim of this treatment is to achieve a soft handle to facilitate the processability and improve wettability. In this study, it was aimed to investigate the effect and washing durability of various softeners on handle properties of cotton and bamboo knitted fabrics. Six types of softeners were applied to the fabrics. Moreover, the washing durability of the softeners after 5, 10 and 20 washing cycles were tested. Handle characteristics such as drapeability, kinetic friction coefficient and circular bending rigidity were measured. The results were statistically evaluated. It was determined that softening treatment does not have a successful performance in bamboo fabrics as it has in cotton fabrics.

 Abstract 
The  present  paper  aims  to  investigate  the  practice  of  upcycling  and  redesign.  The  study  draws  on  the  multiple organizations involved in the redesigning activities. The organizations selected for the study are located in the northern part of Romania. Semi-structured interviews along with direct observations were used to collect information. The paper provides practical insights to upcycling process. Various kinds of redesigned products are made out of consumer and industrial  wastes  such  as  redesigned  clothes,  accessories  for  ladies,  handbags,  ladies  purses  and  office  stationery. Upcycling is generally considered as economically non-feasible. However, this study has found contradictory results. The demand-based redesign activities can help an organization to earn a profit. Two out of three selected organizations areable to self-sustain. One of the organizations is newly entered into the Romanian used clothing markets and ables to compete with existing players. This study could be seen as one of the early attempts to empirically explore the practice of textile and accessories upcycling practice in Eastern Europe. The findings from the current case study can provide several useful insights for other similar companies to make redesign activities profitable.

 Abstract 
Due to importance of global supply chain and high-tech exports, importance of new developing markets is gradually increasing. Turkey keeps the strategic importance for textile sector being in the center of Balkans, Asia, Middle East, North Africa, Eastern Europe and Russia. The geographical location allowing trade in the region makes the country much more advantageous than its competitors. However, devaluation and the exchange rate volatility of Turkish Lira in 2018 have been seriously affecting Turkish textile sector. This study aims to determine the impact of exchange rate fluctuation on Turkish textile firms’ performance between the years of 2013 and 2017. Additionally, multiple regression analysis was done in order to investigate the impact of firms’ performance such as firm age and firm size on performance of the textile firms. According to results, it was observed that exchange rate volatility had a negative effect on the firm performance and the firm size hada negative effect on firm performance while the firm age did not have any influence on firms’ performance significantly.
