Abstract

The aim of this study is to investigate the effect of extraction treatment method on the properties of WPF (Washingtonia palm fibres). The employed treatment is a combined mechanical and chemical sodium hydroxide. The treatment processes was described and evaluated. The physical properties (linear density, diameter and extraction yield), and the mechanical properties (tenacity) of WPF were measured. The optimum extraction condition has been determined by a statistical study using desirability function. Obtained fibres under optimal conditions were characterized with morphological test (SEM), chemical tests (FT-IR spectra, X ray diffraction) and thermal test (TGA). Fibre obtained can be employed on technical textile applications and in particular drylaid nonwoven.

Abstract

With the rapid development of garments recommendation systems, more and more garment knowledge base have been widely developed. The research in this paper aims to build a garment knowledge base in order to help general consumers to identify the most relevant products satisfying their specific requirements. We design four experiments for building this knowledge base by 8 pairs of normalized sensory evaluation criteria for describing both consumers’ expectations and product profile. The theory of fuzzy composition technology is applied for setting up garment knowledge base which can be used for consumer-oriented intelligent garment recommendation system. Compared with the other knowledge base, this knowledge base is more robust and more interpretable owing to its capacity of handling vague, imprecise, uncertain, or ambiguous.

Abstract

Attempt has been made to assess the cotton/modal (60:40) blended woven fabric properties after mercerization with caustic lye of different strengths. Cotton/Modal (60:40) fabric was subjected to bulk mercerization process and subsequently dyed with reactive dyes. The colour strength, fastness properties (washing, staining and rubbing etc.), tensile and tear strength and shrinkage were characterized. The results of this study indicate that cotton/modal blended fabric that was considered in this study can be processed under similar conditions as those that are maintained for cotton fabrics generally and that the aforementioned properties are improved generally.

Abstract

Fabrics for electromagnetic shielding are especially relevant in nowadays context, contributing to human’s protection and wellbeing and to proper functioning of electronic equipment, in relation to electromagnetic compatibility. Fabrics with electromagnetic shielding properties employ two main technologies, namely insertion of conductive yarns and application of conductive coatings. Magnetron sputtering is a modern technology to enable conductive coatings with thickness in the range of nanometers onto fabrics. This paper aims to analyze contribution of various conductive textile structures out of both fabrics with inserted conductive yarns and coatings to Electromagnetic shielding effectiveness (EMSE). EMSE was measured in the frequency range of 0.1–1000 MHz by using a TEM cell according to standard ASTM ES-07. Results show a gain of 10–25 dB when introducing silver yarns in warp/ weft direction, a variation of 5–35 dB between conductive yarns out of silver and stainless steel and an up to 12 dB gain out of thin copper coating by magnetron plasma onto the fabrics with inserted conductive yarns.

Abstract

The paper aims to highlight the correlations between the physical-mechanical properties of woven fabrics made of combed wool yarn with different fibrous compositions, using the Principal Component Analysis (PCA) method. Based on the information on each fabric/assortment group, it is found that four main factors were extracted: durability, comfort, production price and fabric design. The extracted components explain 92% of the variability of the twelve initial inter-correlated variables, so that we can considerably reduce the complexity of the data configured using these components, with only 8% loss of information. This technique that follows the controlled reduction of the number of variables can be used subsequently for modelling the physical-mechanical properties of the fabrics and for selecting the most suitable fabrics to satisfy the requirements of a particular field of use.

Abstract

This paper presents multivariate analyses of the experimental parameters obtained in the scientific experiments on eight sample fabrics of 100% cotton with electrically conductive properties and electromagnetic achieved through traditional treatments such as padding with antistatic agents, and direct printing or scraping with a polymeric paste based on nickel (Ni). Textile printing was obtained using polymers such as polyethylene glycol (PEG), polyvinyl alcohol (PVA), polyacrylate, ammonium salt, carboxylic acid Copolymer polyester, and Ni microparticles. For the eight samples that have been analyzed, the morphology of the surfaces using SEM (scanning electron microscope) with magnification 2000–8000x and electronic magnification microscopy with 4x, assessed the resistance to wet rubbing and dry the resistance of the surface after treatment in the solution of alkaline and acid sweat. Also, the samples above referred have been analyzed by spectrophotometry to evaluate the transmittance, and reflectance of the electromagnetic waves. It can specify that after treatments in acid or alkaline sweat solutions, the resistance of the surface has decreased by 103–105. It has been observed that for samples treated with acid or alkaline sweat, the reflectance was increased in comparison with the reflectance obtained for the original samples. The multivariate analysis provided refers to the study of some physic-chemical and optical parameters, of the samples collected, such as thickness, pH, reflectance, and transmittance.

Abstract

Aerodynamic parts such as rocket nose and heat shield related composites are mainly produced with filament winding machines. Winding angle of the reinforcement filament is the main parameter to determine the thermomechanical properties of the final composite part. The angle adjustments on the machine cause the temporary response of the filaments. This study derives an analytical method to determine the real angle of the filaments on the mandrel.

Abstract

The purpose of the present study is to provide further evidence of the weak form efficiency of the Bahrain Bourse. The research methodology is based on daily closing index values of the Bahrain Bourse from 2011 to 2015 in order to test the efficiency of the stock market while runs test, Autocorrelation Function, and advance tools such as ARCH and GARCH models and Hurst Index to provide further evidence of the weak form efficiency of the Bahrain stock market. For instance, a volatile and inefficient stock market has a negative impact on textile and apparel industry in the Kingdom of Bahrain, which is one of the most prosperous and attractive industries in the country. The empirical results revealed that Bahrain stock market does not follow normal distribution and the successive price changes are not independent. Further, ARCH effect is significant and indicative of a time-varying conditional volatility. There is an arbitrage opportunity and extreme mispricing in the Bahrain stock market as indicated by the GARCH (1, 1) model. The results of the Hurst exponent also confirm the inefficiency of the market. The results of these tests are consistent indicating that the Bahrain stock market is inefficient.

Abstract

This study emphasizes the factors that may lead to increase the employee performance in the textile sector in Pakistan. The study observes an impact of capacity building, alignment of interest and manager support in employee performance through the moderating role of employee retention. The approach consists in survey questionnaire used to collect data. Data was analysed through SPSS 23 and Smart-PLS 3. The results indicate that manager support, capacity building and the alignment of interest have a noteworthy influence on employee performance. Additionally, if employee retention is considered as a moderator then the overall impact would be more significant to employee performance. According to these results, capacity building, manager support and alignment of interest contribute positively to employee’s performance. The results encourage the managers to invest in training their employees to improve their organizational performance/productivity as well as to consider the alignment of interest as a tactical and operational strategy to retain their key employees.

Abstract

In the fashion, industry brands are especially important, because the competition is high, and companies need to attract new customers and keep them. Successful branding requires a good knowledge of consumers and their purchasing processes. Brands have an important function in the fashion world, both for businesses and consumers. The brand is assured to the consumers by the quality and by acquiring some image and status in the company. A strong brand makes a profit for the company. In addition, a strong brand enables setting high prices and expansion of product range and introducing new products. In the survey, we wanted to examine the behaviour of customers in the clothing brands in the Slovenian market. We used a survey questionnaire to get the appropriate answers. The survey found that most respondents want to buy clothes in larger shopping centres and in the Internet, most often during the sale after the season.

Abstract

The yarn quality depends on many parameters: characteristics parameters, mechanical and physical properties. Making the hypothesis that the quality of the yarn is a multicriteria problem, in this paper, we propose a new method to determine the Quality Yarn Index QYI based on Analytic Hierarchy Process AHP and Fuzzy theory. A questionnaire was designed for experts of each field (weaving and knitting) to evaluate the relative importance for each property to determine coefficients of the AHP matrix. Results revealed that matrix coefficients changed with yarn application (weft or warp weaving and knitting) The QYI can be used in any application, where a rapid decision is needed, to evaluate the global quality of yarn and to make a comparison between different yarn qualities.

Abstract

The present paper proposes a method for an effective analysis of Romanian folk motifs using two basic algorithms – Radius-Vector function (RV) and Principal Component Analysis (PCA). For a better accuracy of the analysis, a combination of these methods has been proposed. The authors selected few Romanian folk motifs (embroidered on blouses, skirts called “poale”, front aprons called “zadii”, sleeveless vest) from Bihor, Arad, and Maramures Counties. The vectorization of traditional motifs was made by GIS software.

Abstract

At European level, there are concrete measures regarding waste management in the circular economy, and these refer to: mandatory recycling rates for different categories of waste: plastics, glass, metals, paper and cardboard as well as biodegradable waste; the obligation to redesign the products in order to increase the proportion of raw materials resulting from recycling and to increase the degree of recycling of products, in order to consider them as secondary raw materials; promoting and stimulating the reuse of products; increasing the recycling rate of municipal waste by 2030 to a minimum of 65%; increasing the recycling rate of packaging waste by 2030 to a minimum of 75%; reduction of food wastage and implicitly of the resulted food waste by 50% by 2030. The large amount of packaging waste determined the taking of legislative measures that defined the obligations of packaging producers/distributors, recycling objectives and the waste management hierarchy. New targets for the recycling of packaging waste predict a growth to 65% in 2025 and 70% in 2030. Textile packaging waste is an important link in the integrated management of waste whose recovery contributes to the conservation and improvement of natural capital.

Abstract

Sustainability in the textile and clothing industry is seen as a subject of the major producers, with many brands divulging their concern about protecting people and the environment and adopting an environmental friendly communication approach. For companies in the textile and clothing sector (especially SMEs), the circular economy provides an opportunity to create new profit streams, increase their resilience to volatile input costs, and support their efforts to become completely sustainable and socially responsible. EU textile and clothing industry needs a flexible workforce that can respond to the development and to the globalised market and the need for sustainable design and manufacturing in order to respond to the global demand for sustainable creative products. In this frame, it is important to have suitable tools to train the employees, to prepare them to deal with these new challenges, to enhance their knowledge, and to develop new skills and competencies for this new type of business. This paper introduces a new training toolkit, which will contribute to the training process of the personnel involved in the textile and clothing industry. This toolkit contains e-learning courses in six European languages, mainly various sources (books, video) and activities (quizzes and forums), which are uploaded and available on the Udemy platform.
