To produce polyethylene fibers protected from breeding of seaweed, copper compound, Cu2O and Cu were mixed with polyethylene in the melt spinning process. The melt spinnabity, the mechanical properties of fibers and the elusion properties of copper ion from fiber were examined. Moreover, the chinning test textile made of molded fibers was carried out in the sea. The highest weight fraction of copper compounds to allow a good melt spinnabity was 25% for Cu2O and 30% for Cu, respectively. However, Cu2O was more effective antifouling material against the seaweed compared with Cu. It is due to the larger amount of copper ion eluted.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120993752","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}

Initial experiments were done on an intersecting gill. Various nip gauges were adjusted on the gill-box and the irregularity of the produced slivers were measured. Generally, in the most of the current reports, it was thought that the irregularity of the sliver increases as the nip gauge increases. The results of our experiments on the gill box do not show a significant change in irregularity of wool sliver when the nip gauge was changed. To investigate more detail about this result, we prepared an experimental apparatus with higher variable nip gauge than that of the gill-box. The withdrawing test was done for various distance between the first faller and withdrawer jaws. As a result, we found that the effect of nip gauge on the irregularity of the sliver depends on the fiber length distribution. In case of wool sliver, because of the fiber length distribution, the effect of nip gauge on the sliver irregularity is not significant in a conventional gill-box with its limited nip gauge range.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121753020","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}

Wetting rate and water remaining rate of the top sheet are also defined from the characteristic curves of remained water.

However modern textile machine systems cannot satisfy it. We have project to develop a spinning system that meets this demand by modeling a human hand spinning system with a spinning wheel and flyer.The purpose of this paper is to examine the principle of a hand spinning system with them from the point of view of control engineering. The rotational speed of the bobbin, position of the right hand, the clamping force of each hand, the thickness of the yarn, etc. were measured in real time. Experimental results revealed that the thickness of the yarn was controlled by the position of the right hand and the twist ratio of the yarn was controlled by the twisting time. Observation and experiment revealed several kinds of human skill such that a slight counter twist action by fingers of the left hand was effective for continuous normal draft operation. Obtained results are useful for the development of the new spinning system mentioned above.","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123260168","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}

Moreover, we derived estimation equation of mechanical parameters and hand values from the textile structure. It was found that there were effects of textile structure on both mechanical parameters and hand values. Those parameters could be estimated from the textile structure, using multiple regression equation. As a result of principal component analysis, 1 g and 2nd component were obtained which mean fabric softness and surface feeling, respectively. Further, it was found that fabrics were classified into three groups such as hard plain weave, soft satin weave, and other weaves.

The fastness of the agent to sunlight was not so excellent. 3) The screening effect of shoji paper can be evaluated by measuring its haze value obtained from the transmittance ratio of light. 4) Machinemade shoji papers using rayon, synthetic fibers, binding agents as well as wood pulp are usually produced under hot pressurized conditions. Thus, the surface of the papers tends to become smooth. Accordingly, the machine-made shoji papers reflect light more directly and luster artificially as compared with hand-made shoji papers prepared from broussonetia kazinoki (Kozo).","PeriodicalId":339262,"journal":{"name":"Sen'i Kikai Gakkaishi (journal of The Textile Machinery Society of Japan)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130508099","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}
