Part 1 : Effect of Flow Pattern in Yarn Guide Pipe on Flying Behaviour of YarnTsuneo Hirai, Naomichi Heya, Teruo Kimura, Mitsuo Koukawa, Sadasuke Fu ...1983 Volume 36 Issue 9 Pages T135-T143

JOURNAL FREE ACCESSThe dynamic behaviour of the yarn conveyed with the flow of air in the curved yarn guide pipe is studied in the present paper. Several different radiuses of curvature of pipes whose cross section remain uniform are used for the test. The results obtained are as follows :
(1) The yarn flies along the side edge of the slot in the pipe, since the jet inhaled through the slot pushes the yarn aside. It is necessary and also sufficient conditions to jump the yarn out of the pipe used to the test that the ten sion developed in the yarn amounts up to the value in which the yarn can penetrate into the jet.
(2) The jumping behaviour is affected principally by the air flow pattern in the section near the upstream edge of the slot, especially by the development of the separation of flow near the upstream edge of the slot and the secondary flow in the cross section of the pipe. When the tension of the yarn reaches the sufficient value to bring the yarn itself into the jet, the yarn begins to jump out of the pipe in the section near the upstream edge of the slot.
(3) The value of the tension of the yarn to jump out of the pipe varies proportionally with the yarn diameter, and is scarcely affected by the feeding speed of the yarn.
(4) The result obtained from the one dimentional analysis for the flow of fluid along the pipe axis is also appli cable for the prediction of the value of tension in the flying yarn.View full abstractDownload PDF (3657K) -
Part 4 : Effect of Water on the Dye Promoting Efficiency of Nonionic SurfactaIsamu Hashimoto, Yoshihiko Imai1983 Volume 36 Issue 9 Pages T144-T150

JOURNAL FREE ACCESSThe effects of water on the dye promoting efficiency of nonionic surfactants for polyethylene terephthalate dyeing with a disperse dye were studied, and the following results were obtained :
(1) Comparing with the hot air treatment, superheated steaming at atmospheric pressure gave much more rapid and high levels of fixation at the same temperature.
(2) Nonionic surfactants greatly accelerated the rate of dyeing and promoted the degree of fixation in both super heated steaming and hot air treatment.
(3) The behavior of disperse dye in the nonionic surfactant system containing a little water closely correlated with the quantity of water involved. The rate of diffussion and the partition coefficient increased with increasing the quantity of water, but the solubilities of dye in nonionic surfactant decreased with increasing the quantity of water.View full abstractDownload PDF (828K) -

JOURNAL FREE ACCESSIn this paper, behavior of Glyezin CD®has been studied when cotton and polyester fibers were dyed with Cellestren®dyes. The following results are obtained :
(1) Dye promoting effects of Glyezin CD was obtained only when cotton was prewet with water before hot air fixation of Cellestren dyes.
(2) Glyezin CD little or does not promote for hot air fixation of polyester fibers with disperse dyes.View full abstractDownload PDF (848K) -
Part 5 : Wear Trials of Underwears in a Climatic ChamberTakashi Harada, Kazuyoshi Tsuchida1983 Volume 36 Issue 9 Pages P392-P399

JOURNAL FREE ACCESSThe wear trials of underwears were performed in a climatic chamber at 10°Cand 25°C. Relations were studied between the temperature and humidity within clothing, the surface temperature of clothing and the residual sweat content of clothing, and wear sensations. A correlation has been investigated between the test results on the simulator and those by the wear trials. The results are summarized as follow :
(1) The temperature and humidity within clothing, the surface teperature of clothing and the residual sweat content of clothing on the wear trials are related to the wear sensations that are influenced by the microclimate within clothing.
(2) The variation of the temperature and humidity within clothing on the simulator is similar to those on the wear trials.
(3) The significant correlation was not found between the wear sensations on the wear trials and the moisture regain, water absorption property and clo value of clothing materials.View full abstractDownload PDF (3871K) -

JOURNAL FREE ACCESSThis study reports the modern womens' consciousness and behaviour of kimono, the Japanese traditional costumes. The investigation has revealed following results :
(1) As shown in the category distribution classified by the wearing frequency of kimonos, women who wear western garments in daily life and kimono on a formal occasion are placed in a highest category of 54.4%. Modern Japanese women wear either kimonos or western garments depending on their social circumstances.
(2) Women's knowledge of wearing ability of and de gree of consciousness of kimonos decreases with lowering womens' age up to 40 years old.
(3) Womens' rating revealed that kimonos were rated low from the view point of practical use. Women regarded kimono impractical in the every day living. By contrast, kimonos were rated high from the social, aesthetical and fashionable point of view. Women regarded kimono as an important medium to most express the beauty of Japanese women. Kimonos have their significance in cere monial garments or fashionable dresses to enjoy the life for modern Japanese women.View full abstractDownload PDF (1230K)
