Ne 30/1 polyester ring spun yarns with knitted twist were produced and some of the PCM nanocapsule and produced yarn properties were analyzed. According to the results, PCM nanocapsules had dimensions around 200-400 nm, uniform size distribution and spherical morphology. They could store approximately 100 j/g heat and had sufficient thermal resistance. With the developed capsule application method, nanocapsules were successfully applied to spun yarn structure and produced polyester yarns exhibited temperature differences in the range of 2-5 °C compared with undoped reference ring spun yarns. The results of the study indicated that this application method could be an alternative to fabricate thermo-regulating fabric surfaces and such integrated yarn materials have demonstrated promising potential for the production of thermoregulating textile material.","PeriodicalId":505914,"journal":{"name":"Tekstil ve Mühendis","volume":"423 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177986","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}

Various concentrations of carvacrol:lanolin were added to the PVP polymer solutions such as 2.5, 5, 7.5, 10, 12.5 and 15 wt %. Solution properties such as viscosity, conductivity, and surface tension were measured. In terms of characterization studies, SEM, FT-IR, TGA and DSC analysis were carried out. According to the results of the study, viscosity increased and conductivity decreased with carvacrol:lanolin concentration increasement. However, surface tension was not affected from carvacrol:lanolin concentration. Nanowebs quality improved with carvacrol:lanolin concentrations. Generally, nanofibers are quite fine, smooth, and uniform. FT-IR spectrums verified that PVP, carvacrol and lanolin exist in the structure of nanofibers chemically. DSC and TGA results demonstrated that the thermal stability of carvacrol and lanolin, which have poor thermal stability, was enhanced by incorporating them into the PVP nanofiber structures. Considering antibacterial properties of carvacrol and wound healing properties of lanolin, these composite nanofiber surfaces have a high potential for use in the biomedical field, especially as a wound dressing.","PeriodicalId":505914,"journal":{"name":"Tekstil ve Mühendis","volume":"27 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139178856","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}

The relation between the dynamic yarn tension (DYT), yarn quality, and production efficiency of the spinning frame cannot be established conclusively. Artificial neural network (ANN) is a promising step in this filed. In this research work, ANNs simulation and modeling is applied for the optimization of the DYT n to improve the production efficiency and quality of yarn. The research to date in DYT is insufficient to meet the developmental requirement of the high-speed and efficient ring spinning frame. One of the major problems facing the effective use of the ANN is the correct selection of the input parameters to be fed for the training of ANNs. Data of various input variables such as count, traveler no., spindle speed and dynamic yarn tension etc., was used for ANN modeling and simulation. DYT plays a significant role in the determination of yarn quality and its productivity in terms of end breakage rate. However, it has never been explained in terms of displacement from the original yarn path. This work is aimed to the determination and optimization of DYT at ring spinning frame. The influence of different yarn geometry parameters on DYT, measured by the tensiometer was investigated. The optimized DYT values for the machines, running at different speed and different counts were determined using ANN modeling. It is found that the optimized values predicted from ANN resulted in better quality, high production, and decreased end-breakage at industrial ring spinning frames. By the implementation of ANNs the optimum speed and effective utilization of textile raw materials can be achieved.","PeriodicalId":505914,"journal":{"name":"Tekstil ve Mühendis","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139307499","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}
