The research performed in recent years regarding synthetic filament yarns is improving the structures and properties of such yarns, and diversifying their usage areas. Most of the current studies being carried out in this field are in the form of bringing functionality to filament yarns. And one of these functional properties is the production of flame-retardant yarns from different types of polymers. In this study, polypropylene (PP) raw material was mixed with organophos- phonate based flame retardancy additive at rates in between 1% and 8% in the feed hopper of a laboratory-type melt spinning machine during PP filament yarn production and then knitted fabric structures were obtained from these yarns. Then the flame retardancy properties of these PP knitted fabrics were tried to be determined by vertical flammability tests and Limit Oxygen Index (LOI) tests. Test results indicated that after flame time and char length values had significantly decreased and values of LOI had increased in knitted fabrics by the increase in additive rate. In conclusion, it was observed that the increase in the rate of flame retardancy additive had significantly improved the non-flammability properties of the PP samples.

Foreign trade is significant for open economies and has a critical place in the development of national economies in a globally competitive environment. Export has a key role as an important component in foreign trade transactions. In this study, Turkey's exports of HS-61 “Apparel and clothing accessories knitted or crocheted” and HS-62 “Apparel and clothing accessories not knitted or crocheted” products were examined. Turkey's exports of these HS codes to seven countries, which are mostly exported, EU27, OECD and the world were estimated for 2020–2025 using artificial neural networks (ANNs). The model was validated by measuring forecast errors (RMSE, MAE, and MAPE) to ensure that the model can recreate satisfactory results. The results reveal that the ANNs predicted the exports to the selected countries accurately. According to the findings from the NNAR (1,1) model, Turkey's exports of HS-61 coded products to Italy, the UK, France and EU-27 are expected to increase year-on-year from 2020 to 2025, while exports to the USA, Netherlands and Spain are expected to decrease. Exports from Turkey to Germany, the world and the OECD are projected to decrease first and then increase. In the NNAR (2,2) model, Turkey's exports to Italy, the UK and France are expected to increase year on year, while exports to other countries are generally estimated to decrease first and then increase. In the estimation made for the HS-62 product group with NNAR (1,1) model, it is predicted that TURKEY’s exports to Italy, the USA, the UK, France and Spain will increase year by year from 2020 to 2025. It is estimated that TURKEY's exports to the Netherlands, Germany, World, OECD and EU-27 will decrease year by year in the same period. In the NNAR (2,2) model, it is predicted that TURKEY's exports to UK, France and Spain will increase year by year, while exports to EU-27, OECD and World will decrease. However, TURKEY's HS-62 exports to Italy, the USA, the Netherlands and Germany are expected to follow a fluctuating course.

Today, with the development of technology, radiation exposure is more common. Therefore, alternative methods have been developed because shielding, which is used as the most effective method for radiation protection, has risks in terms of health. With the awareness of consumers, the use of antibacterial textile products has increased in terms of hygiene and comfort. In this study, for this purpose nano-silver which has antibacterial properties was applied to woven fabrics with the impregnation method and the fabrics were coated with tungsten and barium sulfate, which have radiation shielding properties. The radiation shielding properties of fabrics against 137 Cs source emitting γ radiation were investigated. In this study, woven fabrics with radiation protection and antibacterial properties, which are very important for the health sector, were obtained and compared with each other.

The present study aimed to investigate the permeability of dry-laid, mechanically bonded nonwoven fabrics for filters of five different samples. Various permeability properties were investigated in the experimental part, such as water vapour permeability, air permeability, thermal conductivity, porosity parameters, and surface openness, which affect the permeability properties. The results of the study and statistical confirmation showed that the nonwoven structure has a great influence on filtration performance. It was found that the sample with the largest mass and thickness had the optimal filtration properties, as it had the smallest open area and thus the lowest water vapour permeability, average air permeability, and highest thermal conductivity. Statistical analysis confirmed that water vapour permeability correlates strongly with fibre diameter and bubble point, air permeability correlates strongly with thickness and mass, and thermal conductivity correlates strongly with fibre diameter, thickness, and mass of the nonwovens studied.

In this study, a comparative assessment of the mechanical properties of chopped carbon fibre (CF) reinforced polypropylene (PP), polyethylene (PE), polyamide 6 (PA6), and polyamide 12 (PA12) composites was performed. A variation in the composites was obtained by changing the fibre volume fraction of the composite elements under the same manufacturing method and conditions. After blending reinforcement and matrix materials using the extrusion method, the composite materials were manufactured in the shape of plates with thermoforming. The composites’ tensile and 3-point bending tests were carried out, and the surface morphology of the fractured surfaces was examined by Scanning Electron Microscope (SEM). As the fibre content in all matrices increased, the efficiency of the fibre in the composites decreased. Finally, ANOVA analysis and mathematical model development by the least square optimization method were performed to analyse and fit experimental data. As a result of the ANOVA analysis, it was seen that the matrix type was more effective on the composite than the fibre type. The error of the modelling performed is less than 20% for the tensile and three-point bending tests.

The increasing use of high-value carbon fibre in composites is linked with increasing waste generation. A simple and feasible chopped/hot-press method was proposed for multiple recycled carbon fibre-reinforced thermoplastic composites. The effect of regeneration times on the tension and impact properties of carbon fibre-reinforced polypropylene thermoplastic composites was investigated experimentally. The results showed that the r1-CFRTP specimen decreased by 69.34% in tensile strength and 48.66 % in tensile modulus compared with v-CFRTP. However, its tensile properties were improved with the increase of regeneration times (before 3 times). The impact strength of r2-CFRTP and r3-CFRTP is 12.65%, 20.85% higher than v-CFRTP, while r1-CFRTP and r4-CFRTP are 8.02% and 7.06% lower than v-CFRTP. When the third regeneration makes relatively excellent mechanical properties for recycled carbon fibre/PP composite, the chopped/hot-press method is a meaningful attempt at recycling and reusing the thermoplastic composites.

The Information and Communications Technology sector may be organized into individual technologies or solutions. Theoretical literature review argues digitalization technologies make up enterprise architecture and shape business processes or business models. It also shows contemporary business models market solutions for a given value or impact, rather than sell individual technologies per se. Empirical data confirms enterprise architecture is the market for system integration. Market data shows the market leader is Software AG. The goal of this article is to build a theory with an emerging case example of more technologically and business model sophisticated solutions than the theoretical and market benchmark. The methodology is a dual case study on important market players, Siemens and PTC. The standalone cases allow for similar solutions which cannot be otherwise tested or validated. Reference is also paid to other market players within the article. The empirical data analysis is compared to acceptable benchmarks, theoretical literature review and the enterprise architecture market leader Software AG. Findings show emerging technologies add capability maturity levels to accepted system integration. Network business models with a quantifiable and provable customer value proposition: bespoke or personalized products, reasonable cost per item, and zero inventory achieve the vision of mass customization. The business models are enabled by the highest level of digitalization capability maturity, not considered in the status quo literature review and at the leading enterprise architect. They place the textile industry at the forefront of technological innovation and extended reality-based marketing.

In the present work, the drape characteristics of second-hand textile fabrics were determined. The results can be used to implement the concepts of the circular economy. Automated software tools have been adapted and researched to apply the proposed methods and procedures for digital image analysis of used textile drape, which will be utilized to describe their shapes and predict their characteristics, as well as their classification into groups and assessment of classification accuracy in recognizing their elements. A radius-vector function was used to determine the main drape characteristics, such as the number of peaks, their size, and their location. Analytical models have been created for automated forecasting of the drape characteristics from used textiles, which can be applied to predict changes in these characteristics. It obtained an accuracy of 68–92% in the prediction of the main drape characteristics of used textiles. Due to changes in their main characteristics, the errors in classification and prediction increased by 10–15%. More complex computational procedures have been implemented to obtain a higher predictive power for second-hand textile fabrics. The results can be applied in the manufacture of new products such as curtains, tablecloths, napkins and fashion accessories.

The results can be applied in the manufacture of new products such as curtains, tablecloths, napkins and fashion\u0000accessories.","PeriodicalId":13638,"journal":{"name":"Industria Textila","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48600854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investments in digital technologies are expected to soon have a major impact on the textile and fashion companies’ sustainability and competitiveness. Motivated by these trends empirical research on investments of the fashion and textile companies in ICT technologies-based advancement in the Serbian case was provided in 2022. Representatives of 423 textile and fashion companies were asked about their investments in various digital technologies in the previous three years and their digital transformation status. The research findings show that investments in cloud computing, IT, energy management, automation, robotics, and machine learning technologies have a significant impact on the digital transformation of companies. Most of them reached a medium level of transformation, fewer than a high level, with many textile and fashion companies just defining digital transformation. The contribution of the research findings to the investments in the companies’ digital transformation can be seen in the significance of the textile’s digital technology implementation, which enables manufacturers and retailers to respond directly to market demand by reducing product lead time and cost, increasing supply chain efficiency and profitability, and promising in terms of ensuring competitive advantage in the risk and challenging business environment.
