These secondary flow regions depended on the first normal stress differences of the fluids. The pressure drop per slit, however, was the same through the channel.

In addition, the Y-value of loop pile carpet shows the average Y-value of each monochrome of loop pile carpet. The colorimetry of bright portion (top of the loop) and dark portion (darker portion between the two tops of loops) has shown the remarkable color difference between bright and dark portion.

The effects of shear thinning and elasticity on the fiber orientation have been discussed.The fibers lie tangent to the streamlines with an increase in viscoelasticity in the flow through a parallel plate channel and a channel with an abrupt contraction. This phenomenon is essentially equivalent to the phenomenon that a slender body, namely a straight circular cylinder with a large length to diameter ratio, rotates towards a vertical orientation when falling through a quiescent polymer solution. High fiber alignment to the streamlines, thus, is attributed to the shear thinning and elsticity of the suspending fluids; however, elastic effect is most dominant.The state of fiber orientation is strongly influenced by the drastic change of the velocity field due to viscoelasticity and flow rate: the fibers align in a manner of wine-glass shape as the contraction is approached and then the distribution of fibers abruptly expands in the immediate downstream region of the contraction in a highly elastic fluid flow.","PeriodicalId":17585,"journal":{"name":"Journal of the Textile Machinery Society of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76306059","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}

End breakage in the plain-weft knitting zone due to an air-splice hardly occurs under any knitting condition. Therefore, the air-splice is a very useful yarn joint in weft knitting. The knitting defect due to a weaver's knot or a fisherman's knot is almost always caused by end breakage in the plain-weft knitting zone. This end breakage occurs near the knot on the take-down side. The end breakage rate in the plain-weft knitting zone due to a weaver's knot or a fisherman's knot increases with the increase in the depth of stitch draw, the machine gauge, the input tension, and the take-down weight. Under every knitting condition, the end breakage rate due to a fisherman's knot is more than that due to a weaver's knot.","PeriodicalId":17585,"journal":{"name":"Journal of the Textile Machinery Society of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73883141","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}
