Investigating the effect of recycled cotton included fabrics on the thermal behaviour by using a female thermal manikin

In recent years, with the increase in global awareness of environmental problems, the term “sustainability” became more important for apparel manufacturers and consumers. Therefore, recycling of wastes plays a significant role in environmental sustainability by converting the wastes into raw materials. This study focused on recycled cotton-included fabrics, to evaluate the effect of these fabrics on thermal comfort properties. In this context, first, the 45% recycled cotton/55% polyester blended yarns and 50% virgin cotton/50% blended yarns were obtained. Afterwards, single jersey and rib-structured fabrics were knitted using these yarns. The thermal comfort tests were performed on the fabrics and four long sleeve rounded neck shirts then were manufactured using these fabrics to test by the thermal manikin method. Results showed that the yarns including recycled cotton led to a decrease in the values in air permeability of the fabrics and in the effective clothing insulation of the garments. In contrast, it was observed that, including recycled cotton increased the thermal resistance values of the fabrics.The authors also would like to thank Kempaş İplik Tekstil Ürünleri San. ve Tic.

Review of Challenges and Advances in Modification of Food Package Headspace Gases

Modified Atmosphere Packaging (MAP) has been widely used as an effective way to preserve foods. Fresh produce, meat and meat products, seafood, and dairy products can benefit from modified gaseous atmospheres, which are usually achieved by reducing oxygen and increasing carbon dioxide concentrations, within limits, defined by product tolerances. MAP of fresh produce is particularly challenging because products are living and respiring. Respiration rates depend on several factors including temperature, oxygen, and carbon dioxide concentrations. Balancing package permeation with respiration is challenging, often due to limited selection of practical packaging materials. Failing to remain within tolerance limits of products leads to rapid quality loss. Gas barrier properties of packages determined rate of gas exchange with the external environment and is a critical factor for achieving tolerable levels. Availability of packaging materials that meet requirement of specific produce is essential. Relative permeability of common films to carbon dioxide is about 3 to 6 times of that to oxygen, often leading to package collapse for package atmospheres that benefit from carbon dioxide. Films often fail to provide desired oxygen transmission rates, high carbon dioxide to oxygen selectivity and desired mechanical properties simultaneously. Despite advances, minimal availability and high cost of selective barrier films limit applications of MAP for fresh produce packaging. Therefore, active packaging components and films are being developed and designed to overcome these limitations. Inserts or films that contain active mixtures as gas emitters and/or scavengers are now commercially available. “Clean label” trends are motivating alternative approaches using active packaging components

Effect of Red Cabbage Extract on Minced Nile Perch Fish Patties Vacuum Packaged in High and Low Oxygen Barrier Films

Oxidation of polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish causes loss of product quality. Oxidative rancidity causes loss of nutritional value and undesirable color changes. Therefore, powerful antioxidant extracts may provide a relatively low cost and natural means to reduce oxidation, resulting in longer, higher quality and higher value shelf life of foods. In this study, we measured synergistic effects of red cabbage antioxidant and vacuum packaging on lipid oxidation in fresh tilapia patties using thiobarbituric acid reactive substances (TBARS) assay, peroxide value (PV), pH and color analysis. Concentrated red cabbage extract was obtained using an efficient freeze/thawed method developed in our laboratory (citation). Fresh tilapia patties were prepared with solutions containing 68 ppm of extract concentrate for each 50 gr of fish patties. Samples were stored for 15 days at refrigeration conditions (4±1°C) and analyzed interval between two days for pH, color analysis, and lipid oxidation assessments. Results show that treated and vacuum packaged samples had lower oxidation levels than controls. Lipid peroxide values on treated samples showed benefits through day 12. This work shows that synergistic effect of red cabbage antioxidant extracts and vacuum packaging may represent an inexpensive and natural method for retarding oxidative spoilage of fresh fish

Investigation of phenolic compounds and antioxidant activity in red and yellow onions and a synergistic utilization of skin extract in modified atmosphere packaging of salmon (Salmo salar)

WOS:000628868100001This study investigated potentially synergetic effects of red onion skin extract and modified atmosphere packaging (MAP) on lipid oxidation of salmon. The skin and flesh of red and yellow onions were extracted with water at 25 degrees C, 45 degrees C, 65 degrees C and 90 degrees C, ethanol and acetone in water solutions. Total anthocyanin and polyphenol levels and antioxidant capacity were determined after extraction. Minced salmon samples were mixed with red onion skin extract (ROSE) and packaged under MAP at different O-2 concentrations (0%, 5%, 10% and 15% of total package gas composition) with 40% CO2 and balance N-2. Polyphenol recovery and antioxidant capacity increased for each sample as the extraction temperature increased with hot water use. Water extraction at 90 degrees C provided higher extraction yields than ethanol and acetone in water solutions. The ROSE treatment of fish with MAP reduced lipid oxidation rates as evidenced by a decrease in peroxide value (43%) and thiobarbituric acid reactive substance (TBARS) (30%). The ROSE might effectively suppress the free radicals in a MAP system. A skin extract and MAP application might increase the shelf life of salmon

Research on sportswear buying behavior of university students

Sport is a necessary element for maintaining life in a healthier and more balanced way. There has been a rising trend of wearing sportswear in daily life besides sports. Developments in technology have raised expectations from sportswear. Individuals expect not only durability, design and being fashionable, but also demand performance and clothing comfort. This study aims to investigate university students’ awareness while buying sportswear. Professional sportsmen from Physical Education and Sports School students and Textile Engineering students having technical knowledge about clothes are included in this study. 100 students from each group were interviewed face to face. Results showed that Textile Engineering students pay more attention to technical characteristics due to their knowledge, however, aesthetic properties are revealed to be another important factor affecting buying decision. Buying decision of Physical Education and Sports School students is expected to be positively affected if they are given a seminar about raw material properties
