To effectively use these resources, an well-organized design database must be constructed and a useful searching method must be studied. As to design searching method, searching methods that deal with human subjective information is requested. As a technique for these searching methods, one method to characterize visual feature of textile designs is proposed. In this study, a correspondence was examined between the subjectivity like \"strong impact\" for textile designs and spatial frequencies that are objective visual features for them. In this examination, genetic algorithm was introduced in order to increase the efficiency of processing time. It was presumed that the subjective impressions of \"strong impact\" were related to lower components of spatial frequencies of textile design images. In this result, the textile designs that impress human when human compare designs are similar to the textile designs that are made up of lower spatial frequency components. As to design searches from subjective impressions of \"strong impact,\" lower spatial frequency components that are objective visual features are available for one of subjective searching item.","PeriodicalId":17585,"journal":{"name":"Journal of the Textile Machinery Society of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87685531","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 optimum coating condition for the concentration of metal alkoxide and silane coupling agent make it possible to uniformly coat alumina precursor film on the glass fiber. The organic contents in alumina precursor on the glass fiber increased with the concentration of metal alkoxide. The addition of silane coupling agent led adhesive force between glass fiber and ceramics precursor films to be higher. The alkali-resistance, heat resistance and tensile strength of ceramics precursor coating glass fibers were superior to original glass fiber. The surface of glass fiber was eroded by curing in NaOH aqueous solution at 40°C. However, the morphology of fiber coated by alumina precursor was retained in NaOH aqueous solution. The crack on the surface of glass fiber was formed by heating at 800°C, but, the crack was not observed in the glass fiber coated by alumina precursor. The tensile strength of glass fiber and alumina precursor coating fiber was 60×103and80×103kgf/cm2, respectively.

(2) The end breakage due to an air-splice in the plain-weft knitting zone hardly occurs under every knitting condition. (3) The rate of jammed knots, the end breakage rate for jammed knots and that for knots increase with the increase of the depth of stitch draw, the input tension and the take-down weight for any knot.

Empirically, however, this deflection is considered to be closely related to sewability, but without defining the proper correlation they may have. A series of studies are, therefore, undertaken to find out the correlation between sewabiliity and needle deflection in sewing operation. The present paper is aimed at a proposed method for evaluating the needle deflection. In the method, the deflect-ing force is measured by two gauges attached to the lateral surfaces of a needle shank, and then the deflection is estimated by using a simple needle model.
