ジャーナル フリーUsing a versatile friction tester, a human forefinger was slid against six kinds of plain weave fabrics. The fabric materials were cotton, cupra, nylon, silk, polyester and wool. Fifteen student men cooperated as an examinee in this test. Main aim of the test is to study the relationship between the characteristics feature of tactile sensing based on semantic differential method and the frictional characteristics. To this end, multivariate analysis method was employed. The results are summarized as follows : 1) In the range of the finger press force of 0.5 - 2N, the mean frictional coefficient was independent of the finger press force, of which Amonton-Coulomb's law of friction held. 2) The mean friction coefficient of silk averaged over 15 examinees was as high as 1.05, while that of nylon was as low as 0.70. 3) The human factor was appreciable for the frictional behavior ; i.e., for almost half of the examinees, the frictional signals of both cotton and cupra showed the stick-slip phenomena, but the rests were not. The mean friction coefficient of the finger/fabrics depended on the difference of finger characteristics of individuals. For some of the examinees, the friction coefficient was independent of the kind of fabrics. 4) The lower friction coefficient of the fabrics was recoded in the lower room temperature. 5) Based on the multivariate analysis of the touch sensory test results, the stick-slip type frictional characteristics of cotton and cupra is discussed in relation to the human factor.抄録全体を表示PDF形式でダウンロード (2829K) -

ジャーナル フリーPoly(L-lactic acid)(PLLA) and Pluronic surfactants (poly(ethylene oxide)(PEO)/poly(propylene oxide) (PPO) /poly(ethylene oxide)(PEO) triblock copolymer), with various compositions, were prepared by using the solventcast technique. Chloroform was used as a co-solvent. The effects of the addition of Pluronic on the properties of the PLLA film have been investigated with wide-angle X-ray diffraction, differential scanning calorimetry, in vitro degradation and gel permeation chromatography. As a result, we have the following conclusions : (1) the addition of Pluronic increases crystallinity of PLLA, (2) the addition of Pluronic influences the thermal properties of PLLA, and (3) the hydrolysis of PLLA/Pluronic blends depends on the composition of Pluronic. The decrease of the molecular weight of Pluronic or the increase of PEO contents in Pluronic components accelerates the hydrolysis of PLLA.抄録全体を表示PDF形式でダウンロード (963K) -

ジャーナル フリーTo develop new products, bamboo shijira fabric is compared with conventional cotton shijira fabric. Results show that in shijira fabric : 1) Cotton has more resistance to breaking and more resistance to surface abrasion than bamboo. 2) Compressibility ratio in cotton is higher than in bamboo. 3) Cotton is thicker than bamboo under lighter load and both are similar under heavier load. 4) Warp water absorption speed in cotton is faster and higher than in bamboo. 5) Drying property in cotton is higher than in bamboo. 6) Conventional cotton is superior to bamboo in emphasizing crepe produced by the rib weave of shijira fabric.抄録全体を表示PDF形式でダウンロード (939K)
