The growth of these technologies has been exponential and the application of AM in the textile industry has also been a subject of increased interest in the past few years. The applications are not only for decorative purposes, but also for biomedical and other uses in e-textiles. However, a crucial point for making such assembly is the adhesion between the material and the textile substrate, as well as the premise of meeting demanding wash resistance requirements. This work aims to investigate the possibility of creating sensors by combining textiles with conductive polymeric filaments used in 3D printing. Merging the flexibility of use, mechanical properties and electrical conductivity of the polymeric filaments with the comfort and physical properties of the textiles can be a promising approach to create novel sensing structures. In this document, we give an overview of the recent state of the art of experimental research on adhesion in textile and polymer composites as well as an optimization of the printing parameters with a conductive filament, PI-ETPU. Some results from the printed samples in terms of print quality and electrical resistance are presented. Combining both topics, further work will include printing with conductive filament on textile substrates to study the possibly of creating sensing and electrical connections.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44558690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From this point of view, it can be said that our domestic sheep breeds are meat or dairy sheep breeds. It can be said that the breed with the highest potential to obtain quality fleece in Turkey is Karacabey merino (Turkish merino). The two most critical parameters that determine the quality of a fleece are fineness and length. In order for a fleece to be usable in the worsted weaving industry, its fineness must be 24.94 microns and below, and its length must be longer than 8 cm. However, studies have shown that the percentage of Karacabey merino sheep with wool with a fineness value of less than 24 microns is very low. For this reason, it is thought that sheep breeds with high quality wool yield can be developed in our country with multidisciplinary projects to be carried out especially by textile engineering, zootechnology department of agricultural engineering, and veterinary faculties. In this review article, information is given about the history of merinoization in Turkey, our native merino breeds and previous studies on the fleece characteristics of the Karacabey merino breed.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41829549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the energy savings achieved by using lighter tube in ring spinning machines were examined under spinning mill conditions. Light tube produced by using lower density composites and with thinner wall thickness provides significant energy saving. Another advantage is ability of winding more yarn on the same size tube thanks to thinner wall thickness. As a result of the comparative energy analysis over 1000 hours; Energy saving up to 33.5 MWh/year/machine was found possible with the use of lighter tubes. With the contribution of the advantage of being able to wind more yarn on the tube, the total savings can reach 1825 USD/machine/year.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43404506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not only in the form of plastic bottles, but the microplastics formed from these bottles threaten many areas of life such as soil and ocean pollution. Converting plastic bottle wastes into textile products is one of the effective methods that not only prevents environmental pollution caused by these materials but also ensures the reuse of raw materials. In this study, the properties of blended yarns produced using viscose fibers and recycled polyethylene terephthalate fibers (r-PET) obtained from recycling plastic bottles were investigated. Within the scope of the study, blended yarns at the ratios of 33-67%, 50-50%, 67%-33% r-PET/viscose fibers, and also 100% r-PET yarns were produced. The physical, mechanical, and structural properties and also cross-sectional images of the yarns examined. The results show that the blending ratio is statistically significant on the yarn properties in general. Among the measured properties, yarns containing 33% and 50% r-PET fibers generally show similar physical, structural and mechanical properties. It is revealed that blended yarns consisting of 67% r-PET have generally better properties in comparison with other types of blended yarns. Therefore, it is possible that higher r-Pet fiber fraction in yarn can create more positive effects on yarn properties and the results are comparable with 100% r-PET yarns.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46486441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to identify fabric-related defects at a facility that manufactures garments and reveal the efficiency of a 4-Point Fabric Inspection System (4P-FIS) that aims to minimize potential losses by the identification of fabric-related defects before the cutting process of the fabric. For this purpose, data were collected through the classification department of a facility that manufactures trousers from woven fabrics that is placed after the cutting department and functions as an additional inspection unit. Accordingly, the cutting department of the studied facility was monitored for 10 days, and the numbers of defects in each defect class were determined by inspecting the cut pieces in the classification process. In the second 10-day period, the necessary inspections were made based on 4P-FIS while the fabrics were still in storage, and the numbers of defects in each defect class were determined. The SPSS Version 22 program was used to analyze the data. The data were subjected to One-way analysis of variance (Oneway Anova), Duncan’s test, correlation analysis and paired-samples t-test to determine the efficiency of the system.

In order for businesses in the ready-made clothing sector to increase their level of competition, they should closely follow the demands and requirements of their customers. Today, it is impossible for businesses to meet customer needs by themself. Therefore, businesses need suppliers in the production process and they need to choose suppliers by taking many criteria into account. For this reason, it is very important for businesses to choose the best supplier that will meet the needs of their customers and can provide high quality products at low prices and at the desired time. Based on this importance, the aim of the study is to choose the best fabric supplier for a business operating in the ready-made clothing sector in Giresun. As a result of the literature research and interviews with the experts in the business, 13 criteria were determined. An integrated approach, in which DEMATEL and COPRAS methods are used together, has been adopted in order to determine the best supplier for a business operating in the ready-made clothing industry.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47766651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon nanotube (CNT), Poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS), and CNT/PEDOT:PSS composites were used as temperature sensitive materials. Performance comparison of three different types of sensors was discussed. To evaluate the sensor sensitivity, the electrical resistance of the sensors was measured at temperatures ranging from 25 to 50 o C and under 65% and 85% relative humidity. Experimental results show that the sensor resistance can vary depending on the relative humidity and the selected material properties. Although the lowest measurement sensitivity in different humidity environments is in the CNT ink printed sensor, when the relative humidity rises from 65% to 85%, the change in temperature resistance coefficient (TCR, α) was found to be higher compared to the CNT/PEDOT: PSS composite ink printed sensor. The temperature sensor that exhibits the best stability to the change against 65-85% relative humidity is found to be CNT/ PEDOT: PSS composite ink printed temperature sensor (TCR change = 0.02 ° C -1 ). Therefore, it is more suitable to use CNT/ PEDOT: PSS composite ink printed temperature sensor for temperature sensor applications where the environmental conditions include 65-85% relative humidity. In general, it is concluded that temperature sensors containing CNT are less affected by humidity than temperature sensors containing PEDOT: PSS.","PeriodicalId":35281,"journal":{"name":"Tekstil ve Muhendis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46478264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
