In this framework, the evolution of the orientation of thin micro-particles such as talc and mica, which were modeled by a disk-like particle, in a flow through a slit channel was analyzed to obtain the knowledge of the processing operations of thin micro-particle reinforced composites.The thin disk-like particles were subjected by a planar extensional flow in a reservoir, then by a simple shear flow through a slit channel in the experimental apparatus used. The evolution of the orientation of thin disk-like particles was, therefore, studied in both a planar extensional and simple shear flows by numerical calculation of the Jeffery equation: thin disk-like particles aligned in a parallel orientation to upper- and lower-walls of the slit channel in a planar extensional flow through the reservoir, then entered into the inlet of the slit channel. On the other hand, in a simple shear flow through the slit channel, the disk-like particles kept this parallel orientation except the occurrence of a flip-over phenomenon. The period of the flip-over became longer with a decrease in the aspect ratio of the disk-like particles.Furthermore, the measurements of the orientation of the talc particles in a suspension flow through the slit channel clearly showed that almost the same period of the flip-over was found although the particle size was different. These experimental results arise from complex geometries and no accurate data of the thickness of the talc particles.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129493758","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 the authors' previous paper, characteristics of the biodegradation and strength for the biodegradable plastic, Poly (butylen succinate) (PBS), and the PBS composite reinforced by cotton (PBS/CO) were examined.In this study, using a PBS composite material strengthened by silk fiber (PBS/SI), biodegradation and tensile tests were carried out as well as PBS/CO, and the properties of biodegradation and tensile strength for the PBS composites were examined. The mechanisms of the biodegradation and the property change in the tensile strength due to the biodegradation test were also discussed from the observation of surface and fracture surface of specimen after the biodegradation and tensile tests.Tensile strength in PBS/SI is much higher than that in PBS before the biodegradation test but decreases drastically after the biodegradation test. The reduction in strength attributes to the adhesion between fiber and matrix interface rather than the biodegradation.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115351307","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 relative velocity of airflow around a yarn was expanded up to 300 m/s. Previously, this had been investigated up to 100 m/s. Both the supplying air pressure and combinations of nozzles and pipes changed diffusion of the flow in a pipe. Air drag force increased extremely if the primary stream acted on the yarn directly when the jet from the nozzle was directed at very high speed (around sonic velocity). Yarn was often stuck inside the pipe by the airflow when very thin pipes were used. When this occurred, air drag force was reduced to half. The air drag coefficient Cf for monofilament yarn has been arranged using the radius Reynolds number, Rea, for suction flow with lower than 100 m/s. The formula, Cf = KRea-n, has been applied for suction flow under 500 in Rea. Cf could be arranged in the same manner for annular jet or confined jet if airflow acted on a yarn in the pipe uniformly. This formula, then, is also available even for very high velocity over 100 m/s. According to these results, we were able to calculate air drag force on monofilament yam. We anticipate applying this to the other kinds of yarn, and expect air power savings and improvement in yarn operation.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130579544","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}
