The yarn structure analysis method is based on HPD-analysis. In this analysis, HPD (Helical Path Difference) is defined as the accumulation of difference between the mean helical paths of two fiber assemblies consisting of the two-layered yarn. The yarn structure change is caused by the variation of mutual dynamic balance of two fiber assemblies. Then it can be analyzed by investigating the mutual relation between two helical paths that represent these two fiber assemblies. It is proved experimentally that the doubling of two fleeces gives no particular influence on the yarn structure formation in spinning process. Our results therefore may be useful and valuable in controlling the yarn structure.","PeriodicalId":17585,"journal":{"name":"Journal of the Textile Machinery Society of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88043817","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}

Results obtained are as follows. The number of tangles measured with the sensor agrees excellently with that by eye when yarns are well interlaced. The relation between the distance between tangling parts and its relative frequency is discussed, and the frequency obtained with the sensor almost agrees with that by eye. Yams with a large number of tangles have not only a small standard deviation of the distance between tangling parts but also a large interlacing effect index, which represents both the number of tangles and the distinction between opening and tangling parts. Therefore, it can be said that interlaced yarns are qualitatively evaluated from only the number of tangles.","PeriodicalId":17585,"journal":{"name":"Journal of the Textile Machinery Society of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73534384","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}
