Functional textile preferences of elderly people

Aging is an inevitable stage of lifetime bringing along physical and emotional deterioration. Rate of aging population in the world has been constantly rising with the contribution of technological improvements on life quality, and medical services. Depending on the unavoidable physical and emotional changes of aging human body, clothing preferences and needs become different then needs of other textile and clothing consumer groups. Textile and clothing products are one of the basic needs of human kind. Sufficient and appropriate clothing is especially important for life quality improvement at elderly stage of human life. New generation functional and smart textile and clothing products bring new opportunities to improve life quality of elderly people with such wide range products of mobility support clothing, medical help, hygiene, and health monitoring textile and clothing products. This survey based research work is aimed to search the awareness level and priority of society about the functional and smart textile products for elderly people. It has been found that gender difference has significant influence on preference level of functional textile products, where women has higher interest then men about functional textiles. It can also be stated that comfort properties are primarily preferred preferences comparing to the fashion and functionality properties of textile products. © 2015, Mediterranean Center of Social and Educational Research.

FASHION INDUSTRY CHARTER FOR CLIMATE ACTION AND GLOBAL FASHION INDUSTRY

Fashion Industry Charter for Climate Action is consequence of a long-term international meeting chain, called the COP-Conference of Parties. The COP is an international climate conference that unites the signatory countries (195 countries + the European Union) of the United Nations Framework Convention on Climate Change (UNFCCC) since 1995. The goal of the consecutive meeting chain is to manage the interiorization of the Convention and negotiate new commitments. Fashion Industry Charter for Climate Action is prepared and launched by the patronage of UN Climate Change at COP24 in Katowice, Poland, in December 2018 and renewed at COP26 in Glasgow, UK, in November 2021. The stakeholder of the charter is the global fashion stakeholders including textile, apparel and clothing industries with a holistic commitment. The charter contains the vision to achieve net zero emissions by 2050 in line with keeping global warming below 1.5°C from pre-industrial levels defined in the COP 21 of Paris Agreement in 2015. In line with the launched charter, planned tasks of global fashion industry are focused on decarbonisation, reduction of greenhouse gas emission (GHG), renewable electricity utilization across supply chains, implementation of tools and measures about broadening climate actions. Therefore, the paper is aimed to inform and increase the awareness about current climate actions of global fashion industry

QUANTITATIVE ASSESSMENT OF POSTGRADUATE THESES IN TÜRKİYE ABOUT YARN PRODUCTION TECHNOLOGY

Yarn and spinning technology is a complex process that is a combination of raw materials, machinery, and automation technology where continuous improvements, researches and innovations run progressively. For the evolution of spinning technology, academic publications, postgraduate theses, and technological contributions of related shareholders must be considered as adherent supplements. Aim of this study is to examine the accomplished 236 postgraduate theses related to conventional and novel textile fibre types, staple spun/filament yarn technology and machinery, yarn types with structural and functional varieties, and modified spinning technologies in Turkish Universities. Moreover, it is aimed to reveal any trend in theses on yarn technology and the regional textile clusters in Türkiye. The methodology of the pursuit is a quantitative assessment where postgraduate level, thesis subject, year of thesis defence, and raw materials used in the theses are concerned. The findings showed that researchers focussed on conventional spinning systems and yarns in parallel with the spinning capacity and import potential of the country. Other extractions of the study are; classical ring system is mostly studied by the researchers, modern spinning technologies are included in many theses, reflections of global circumstances are distinguished in theses with keywords of manmade/recycled fibres, and blended yarns

Neden organik pamuk?

Günümüzde modern pamuk tarımında kullanılan gübre ve diğer yardımcı kimyasallar doğal hayat dengesini ciddi boyutlarda tehdit eder durumdadır. Dünya üzerinde tarım yapılan toplam arazi içinde, pamuk tarımının yapıldığı alan %3 oranında bir paya sahiptir. Bununla birlikte bu alanlarda kullanılan toplam kimyasallar, tüm dünyada kullanılan tarımsal amaçlı kimyasalların %25'ini oluşturmaktadır. Tarımsal kirliliğe yol açan kimyasalların yoğun olarak kullanıldığı modern pamuk tarımı yöntemlerine tepki olarak gelişen çevre bilinci ile birlikte yeni alternatifler aranmaya başlanmış ve alternatif olarak 4000 yıl sonra bir kez daha organik pamuk tarımı ortaya konmuştur

ANALYSIS OF RIBBONING ON CONICAL YARN PACKAGE WOUND BY OPENEND SPINNING MACHINES

In this paper, Ribboning , one of the common faults in yarn packages, is mathematically analysed. If yarn is repeatly laid on top of or along the same path as the previously wound yarn, this duplication of yarn path on the package creates a defect known as ribboning. The number of turns of package (n) per double traverse of yarn guide is calculated in two different way One is calculated the length of a coil on the package and total length of yarn in a double traverse; the other is considered transmission rate between drum and conical yarn package The result of two different approach is similar and the probable diameter of conical yarn package which ribboning is occurred is calculated and used on Schalafhorst-Autocore OE spinning machines

Synthesis of a new dobby mechanism

In this paper the newly designed dobby construction is introduced. Dobby mechanisms are used to control elevation of frames which designate directly the warp motion and indirectly the structure of fabric on some types of weaving machines. The proposed mechanism is an electronically controlled, sixteen harnesses, middle closed, and positive dobby construction. Experimental working speed of the proposed mechanism has been reached up to 604 rpm, with convenient manufacturing cost and acceptable level of working noise. Main innovative value of the proposed dobby is absence of any reciprocating knife-hook pair in the mechanism

Moisture management and antimicrobial performance of collagen peptide enriched knitted fabrics

Knitted fabrics made of natural, synthetic and regenerated fibres are presented to the final consumers at different fabric constructions. Reason to select different fibre types, fibre blends, and knitting constructions utilisation is to optimize consumer demands of comfort, functionality, fashion and price. Continuous fibre improving studies are one driving factor behind the fabric and clothing design possibilities. Collagen peptide added fibres are one recent fibre type in the regenerated cellulosic fibre family. Collagen peptide addition to the regenerated cellulosic fibre has been reported to improve fibre properties of moisture management, thermoregulation, anti-static, ultraviolet protection, biodegradable properties which make the fibre preferable material for active wear clothes. This study involves with the influence of new fibre type addition on moisture management, antimicrobial, and air permeability properties of the plated knitted fabric structures. Within this work; one plain knitted fabric is knitted using 100% collagen peptide added regenerated cellulosic yarn and polyamide yarn grounded six different plated knitted fabrics were studied. Moisture management transport (MMT) properties, antimicrobial properties (against Escherichia coli, Staphylococcus aureus and Candida albicans) and air permeability properties of those knitted samples were evaluated comparatively. Gathered results are statistically evaluated using one-way Anova test; it was determined that there was a significant difference on MMT and air permeability properties of knitted samples at significance level of 0.05. Additionally, presence of collagen peptide added fibre exhibits considerable level of antimicrobial effect against included microorganisms. The results of the experimental work represent an initial phase towards a better understanding of the influence of different fibre blended yarn utilization on plated knitted fabrics which would be appropriate for active wear cloth manufacturing. © 2020 The Textile Institute

PHYSICAL PROPERTIES OF ANTIBACTERIAL TREATED COTTON FABRICS AND EFFECT OF LAUNDRY CYCLE

During daily usage of textiles, humidity and warmth conditions provide appropriate living conditions for bacteria and microorganisms in textile products. Bacteria growth, infection and cross infection by pathogens might develop due to usage of textile products. Especially since World War II, antibacterial textile products have developed as a result of the hygiene demand of the society. In this study, triclosan (sample A), quaternary ammonium plus triclosan (sample B), dichlorophenol (sample C), silver (sample D), quaternary ammonium (sample E) and chitosan (sample F) based six different antibacterial additives were applied on 100% cotton fabrics for antibacterial treatment. All six treated fabrics and the untreated fabric (control sample) were washed for 40 cycles; the antibacterial efficacies were tested; changes in tear strength and Berger whiteness values of the samples were recorded prior to washing and after 1st, 5th, 10th, 20th and 40th washing cycles. Regarding all washing cycles, a decrease in tear strength results is observed between unwashed and 40 cycle washed samples. Textile materials such as bedlinen, pillow cases, surgeon gowns for which tear strength values are important and that have antibacterial treatments should be tested for tear strength values for different washing cycles to see if they meet minimum tear strength requirements. The change in tear strength and Berger whiteness of samples shows differences according to the antibacterial agent treated and washing cycle applied. Generally, slight decreases in tear strength values are observed. And slight decreases in whiteness, except for sample F which is treated with chitosan, are observed as well. Textile materials having antibacterial treatments should be tested for the special antibacterial agent they are treated and for the number of washing cycles that is required for their product life
