With a remarkable structure and versatility, silk has emerged as a topic of scientific study perennially because of its chemical, physical and biological properties. Meanwhile, in order to have an omnifaceted understanding of silk, the environmental performance of silk production is also worthy of attention. With the concern of global warming, efforts are increasingly focused on understanding and addressing carbon emission in the life cycle of silk products. However, the majority of current studies give priority to the carbon emission of either just one or a few stages of silk products’ life cycle, or to a specific type of silk product. On the basis of a review of literature on the life cycle assessment of silk products, this study presents a full-scale review of the quantification of the carbon emission and carbon neutrality of cocoon acquisition, industrial production of silk products, distribution, consumption, and recycling. The analysis revealed that the carbon sequestration by photosynthesis at the stage of cocoon acquisition could not be ignored. It is of importance to establish complete and unified system boundaries when quantifying carbon emissions in the industrial production of silk products. Reasonable models of washing times and washing modes are needed to assess carbon emissions in the domestic laundry of silk products. At the end of life phase of silk products, the positive impact on carbon emission in the phase of silk recycling is noteworthy. This study will help interested scholars, manufacturers and consumers to gain an in-depth understanding of the carbon emissions and carbon neutrality of silk products, and it is also of great value for exploring new production processes for reducing carbon emissions of silk products.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Surface Treatments of Natural Fibres in Fibre Reinforced Composites: A Review<abstract> <title style='display:none'>Abstract</title> <p>The use of natural fibres in fibre-reinforced composites comes with drawbacks. They are highly hydrophilic, leading to high moisture absorption and poor interfacial adhesion in matrix-reinforcement bonds. This affects the fibres’ thermal stability as well as mechanical properties, hence limiting their wider application. This paper reviewed different ways in which natural fibres have been treated to improve hydrophobicity, reinforcement-matrix interfacial adhesion and thermal stability. It will investigate. among others, treatments like alkali, acetylation, bleaching, silane, benzoylation and plasma, which have been found to improve fibre hydrophobicity. The literature reviewed showed that these methods work to improve mechanical, chemical, and morphological properties of natural fibres by removing the amorphous surface, thus allowing for more efficient load transfer on the fibre-matrix surface. Studies in the literature found alkali treatment to be the most common surface modification treatment due to its simplicity and effectiveness. However, plasma treatment has emerged due to its lower processing time and chemical consumption. A comparative analysis of other improved properties was also investigated.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Prioritisation and Analysis of Faults in Shirt Production by the A3 Technique<abstract> <title style='display:none'>Abstract</title> <p>In this study, it was aimed to solve the problems occurring in a clothing company’s shirt manufacturing line. For this Pareto charts and A3 reporting philosophy were used to organise the process in the best way. In line with the examinations and analyses made, an apparatus was developed to shorten the unit time and standardise the quality for the collar preparation process, which is the fault with the highest frequency. Afterward, the collar preparation process was compared according to the situation with the apparatus, manual and automat. As a result of the implementation of the Pareto charts and A3 reporting technique, it can be seen that while the total time spent on the process with the automat is 24.6 seconds, this time is 87% quicker than the apparatus developed, which is 46.2 seconds; however, it needs 95% more investment.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Effects of Covid-19 Pandemic on Supply Chain Management in the Clothing Sector and Possible Solutions<abstract> <title style='display:none'>Abstract</title> <p>The clothing sector is one which possesses significance in global trade. The sector has been negatively affected by the pandemic due to its labor-intensive structure and possession of a relatively long and global supply chain. At this point, the Turkish clothing sector, which is the sixth biggest clothing supplier in the world, the third biggest clothing supplier in the European Union, and comprised 10% of Turkey’s general exports in 2019, should be investigated. In this context, this research aims to determine the effects of the COVID-19 pandemic on supply chain management in the Turkish clothing sector. Also, it aims to specify possible solutions against the negative effects of the COVID-19 pandemic.</p> <p>In accordance with the aim of the research, a survey was conducted in clothing enterprises. 391 survey questionnaires were incorporated into the research. According to the research results, it is determined that supply chain management in the Turkish clothing sector has been negatively affected by the COVID-19 pandemic. Order disruptions and cessations have ruined employment, production, procurement and investment processes resulting in financial disruptions. The most significant possible precautions that can be taken by enterprises that can be indicated as follows: benefiting from government support, heading towards online trade and an omni-channel strategy, actualising necessary alterations in product ranges, giving essential importance to innovation, efficient use of occupational health and safety systems, shortening the supply chain as far as possible, integrating digitalisation into all processes of the supply chain, and increasing the efficiency of marketing activities.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Modification of PP Fabric with Polyols by the Plasma Composite Technique<abstract> <title style='display:none'>Abstract</title> <p>In order to endow polypropylene (PP) fabric with hydrophilic and antistatic properties, PP was grafted with polyols (sorbitol, maltitol and polyethylene glycol (PEG)) by the oxygen plasma treatment and subsequent bridging process, where ethylene glycol diglycidyl ether (EGDE) and trimethylolpropanetris (2-methyl-1-aziridinepropionate) (TTMA) were used as crosslinkers. The highest grafting rate was 7.48%. The chemical structure changes were analysed by Fourier transform infrared spectroscopy (FTIR). A scanning electron microscope (SEM) was used to observe the changes in polypropylene fiber surface morphology. The hydrophilicity was characterized by testing loose fiber suspension and moisture retention. The modified PP was more easily immersed in water and the desorption behaviour continued for 2h without equilibrium. The half-life of the grafted PP was reduced to 7s. The results showed that the modified PP with polyols possessed hydrophilicity and antistatic properties.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Analysis of the Correlation Between Crimp Parameters and its Effect on Yarn Strength and Hairiness<abstract> <title style='display:none'>Abstract</title> <p>The objective of this paper is to analyse the correlation between crimp parameters and the effect of crimps on yarn strength and hairiness. Crimp is an essential property for natural and man-made fibres. Crimps always form with different parameters as they are very much irregular in size and shape. So, if the crimps are regular in size and shape, the end products like yarn and fabric properties will improve. Jute is a natural fibre with no natural crimp. In this research work, the gear crimping method was used as a mechanical crimping system to impart a regular size and shape of crimps into jute sliver. As a result, crimp parameters like the crimp length and crimp angle become uniform, and it is then easy to measure them. Results also showed that the crimp length is directly proportional and the crimp angle is reversely proportional to the number of crimps per unit length, and they are highly correlated. It was also shown that crimp and crimp parameters also affect the yarn strength and hairiness. In conclusion, it is revealed that with an increase in the number of crimps, the yarn strength was increased and hairiness was decreased.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Indigenous Costume Color of Bangladesh: A Traditional Context for Cultural Revival<abstract> <title style='display:none'>Abstract</title> <p>Traditional elements are generally influenced as the symbols of cultural context that contains the sign of the past.

Four kinds of composites with the following laying angles: [0°]<sub>8</sub>, [0°/45°/90°/−45°]<sub>s</sub>, [0°/90°]<sub>4</sub> and [45°/−45°]<sub>4</sub> were prepared and tested in three-point bending experiments. The results obtained showed that the bending resistance performance was the best when the laying angle was [0°]<sub>8</sub>, while it was the worst when the laying angle was [45°/−45°]<sub>4</sub>. Besides, it was found that the tensile performance was the best when the fibers were arranged in the 0° direction when the strength utilisation rate was the highest. In addition, by observing the failure morphologies of the composites, the delamination and foam cracking were found in the four groups of composites. In contrast, the phenomenon of significant fracture was found on composites with a laying angle of [45°/−45°]<sub>4</sub> only, indicating it had a poor bending resistance performance.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Effect of ISO (9001) Certification and Article Type Produced on Lean Six Sigma Application Successes: a Case Study Within Textile Companies<abstract> <title style='display:none'>Abstract</title> <p>This study focused on how the ISO 9001:2008 standard has influenced organisational Lean Six Sigma (LSS) implementation success. Data were collected through a survey, followed by interviews with the quality managers/representatives of 85 small and medium enterprises (SMEs) in the textile industry. Additionally, case studies on four of the textile SMEs were carried out to validate the results. Our analysis revealed that the main benefits of LSS, among others, are problem solving improvement, reduction of the quality problem, waste reduction, and increase of productivity. However, certified companies are aware of continuous improvements to tools, which ensures the continuity of improvements made by the LSS project and facilitates the integration of Lean Six Sigma tools, which can help to make better use of the Lean Six Sigma project. The type of article produced was also found to have a considerable effect on the success of the Lean Six Sigma project.</p> </abstract>ARTICLE2022-06-08T00:00:00.000+00:00Removal of Heavy Metals from Aqueous Solutions with the Use of Lignins and Biomass<abstract> <title style='display:none'>Abstract</title> <p>The overproduction of pollutants resulting from the development of industry causes the deposition of large amounts of toxic and carcinogenic substances, including heavy metals, in the aquatic ecosystem and other ecosystems. This is a civilisation problem of the present times, posing a serious threat to the natural environment, including humans. For this reason, it has recently become extremely important to develop effective methods to minimise the concentration of heavy metal ions in the aquatic systems and thus reduce their negative impact on the environment. One such technique is adsorption, which is believed to be an effective method of removing contaminants such as heavy metal ions from aqueous solutions. Looking at the available literature of the last few years, it can be concluded that adsorbents of natural origin are becoming more and more important. These are agricultural waste, all kinds of biomass, and waste from various industries. The study attempts to present and evaluate the sorption capacity of materials of natural origin, including oat bran, chitosan, alginate, tree bark, coconut fibre, and lignin. The use of such biosorbents is more friendly for the environment compared to their synthetic counterparts and perfectly fits the concept of sustainable development and the circular economy.</p> </abstract>ARTICLE2022-06-02T00:00:00.000+00:00Research on the Heating of Woven Carbon Fiber Fabrics Using Thin-Film Solar Cells<abstract> <title style='display:none'>Abstract</title> <p>This study attempted to fabricate heating fabrics using thin-film solar cells. A lightweight and flexible thin-film solar cell was used as the power supply, and fabric samples made of carbon fiber heating lines were used as heating elements. Single-factor experiments of three factors (solar cell voltage, heating time, and carbon fiber heating line arrangement) were conducted, and their influence on the heating effect was analysed. Orthogonal experiments and variance tests were used to determine the influence of the three factors and the optimal heating process. All influential factors were shown to be statistically significant. This kind of heating fabric can be used in warm clothing or for heated clothing.</p> </abstract>ARTICLE2022-06-02T00:00:00.000+00:00Multi-criteria Decision Making Using Hybrid methods for Supplier Selection in the Clothing Industry<abstract> <title style='display:none'>Abstract</title> <p>Supplier selection and evaluation are among the most critical issues in supply chain management, affecting companies’ performance because of the important role of suppliers in the chain’s profitability. For this reason, it is important for companies to have an objective methodology to evaluate and choose an appropriate supplier based on convenient criteria in a competitive market. Determination of a convenient supplier selection is a multi-criteria decision-making (MCDM) problem. In the literature, several applications of the MCDM methods for supplier evaluation and selection can be found; however, research studies in the clothing industry are still limited. Indeed, apparel supply chain managers have to consider their supplier-related decisions to reduce risks affecting the company’s performance. This study aims to fill this gap by providing apparel manufacturers with different hybrid models for selecting the best supplier. According to a literature review and questionnaire conducted, the main criteria related to supplier selection were identified and determined. Then, the analytic hierarchy process method was performed to determine the criteria’s weights, and then suppliers were ranked using hybrid multicriteria decision-making models (AHP-TOPSIS, AHP-WSM, and AHP-WPM) to select the suitable one in the apparel chain. This research methodology can be considered useful for apparel companies and other industries.</p> </abstract>ARTICLE2022-06-02T00:00:00.000+00:00Decorative Image and Cultural Implication of Embroidery in Jinnan (Southern Shanxi)<abstract> <title style='display:none'>Abstract</title> <p><italic>Jinnan</italic> (<italic>Southern Shanxi</italic>) embroidery is a traditional Chinese folk handicraft.

Physically disabled persons face many occupation related obstacles at work, mainly connected with the presence of architectonic barriers and the occupational environment. An important part of the employment process of locomotor disabled workers is the adjustment of work stations to the worker’s needs, providing workwear, rooms and work plant surrounding adaptation. Analysis of workwear available on the market shows that commercial offers do not cover workwear dedicated especially for physically disabled persons. The main goal of workwear design and construction is to provide complex comfort for the user, whose needs and expectations differ from able-bodied employees. In this study the general assumptions of textile material selection for workwear dedicated for locomotor disabled employees are presented, together with the results of tests carried out for selected textile materials.</p> </abstract>ARTICLE2022-05-28T00:00:00.000+00:00Fabrication and Properties of Self-crimp Side-by-Side Bicomponent Filaments Composed of Polyethylene Terephthalates with Different Intrinsic Viscosity<abstract> <title style='display:none'>Abstract</title> <p>Self-crimp side-by-side bicomponent filaments (SBSBFs) were prepared via melt spinning using two kinds of polyethylene terephthalate (PET) with great disparity of intrinsic viscosity. The influence of the volume ratio on the surface morphology, crystallinity, crimping properties, mechanical properties and shrinkage properties of the bicomponent filaments was investigated using wide-angle X-ray diffraction, a differential scanning calorimetry (DSC), scanning electron microscope, etc. As the proportion of the low-viscosity component increases, the shrinkage in boiling water or hot air, as well as the shrinkage force and the sonic orientation factor of the bicomponent filaments decrease, and the DSC heating curves change from double peaks to a single peak. These phenomena should be ascribed to the high orientation and low crystallinity of the high-viscosity PET component and low orientation and high crystallinity of the low-viscosity PET component. Moreover, the crimp property of the bicomponent filament with a volume ratio of 50:50 is superior to those with other volume ratios.</p> </abstract>ARTICLE2022-05-28T00:00:00.000+00:00en-us-1
