    The influence of sewing factors on the blind stitch (type 103) seam characteristics such as the degree of needle penetration, strength at a penetrated part of fabric and its seam strength was discussed. The results obtained were as follows:
    1) The amount of needle penetration, l was affected by the sewing conditions and fabric properties. The mean values of l were estimated by the multiple regression analysis using explanatory variables such as the location of ridge forming disc, fabric thickness, cover factor, weight, bending rigidity and so on.
    2) A linear relationship was assumed between l and the strength at a penetrated part of fabric. The distribution of the strength can be approximated by either the normal distribution or Weibull distribution more accurately.
    3) When the blind stitch seams were broken due to yarn severance, the behaviors were different from the case of the lockstitch seams. The seam strength at the break of the weakest part was predicted by the theoretical equation.

  • Detachment of Solid Particulate Soils in Fluid
    Part 5: Removal Behavior of Spherical Glass Particles

    In order to estimate the force necessary to detach solid particulate soils, glass particles adhering to a glass plate were removed in the thirdly revised prototype of the washing device, as has already been reported, and the force necessary to detach the soils, FH1/2, was estimated. The particle behavior was recorded on a videotape recorder, and analyzed by VTR system and a personal computer.
    The following results were obtained:
    1) The removal percentage increased with increased washing time and particle size, and was proportional to flow speed.
    2) FH1/2increased with the size of the particle.
    3) The particle behavior was ascertained to be of the two types, that have already been reported, namely A type removal and B type removal.
    4) The particle behavior of type A removal was further identified as types A1and A2. Some particles disappeared from the monitor (removal of type A1), and others were redeposited after having moved from adhesive position (removal of type A2) . As for the flow speed, the A1type removal rate was higher than the A2type removal rate. The moving speed of particles of A1type removal particles was faster than that of A2type removal.

    In the previous paper, we proposed a method of analyzing fashion-style clusters of consumers by using a computer simulation method.
    In this study, we attempted to analyze consumer's fashion-style clusters and dress patterns in the near future by improvement of the simulation software. A questionnaire survey has been made concerning the sense and behavior of apparel fashion of students at T women's university and T women's junior college from the middle of September till the middle of October, 1989. The results of this questionnaire survey were analyzed with the simulation software that had been improved by authors.
    The results obtained were as follows:
    1) The simulation software was improved in the analytical functions for the consumer's dress patterns in the near future and in the form of the indication of the result.
    2) With the improved simulation software, the student's fashion-style clusters and dress patterns in near future were analyzed. Then, the fashion-style clusters to which each student belonged and the dress patterns in the near future were cleared.
    3) In the future, we wish to inquire into the algorithm among certain items with the simulation software in order to get a higher precision of intelligence.
