Part 3 : Frictional Property of Pile FabricsToyonori Nishimatsu, Teiji Sawaki1982 Volume 35 Issue 12 Pages T167-T172

JOURNAL FREE ACCESSThe frictional forces between pile yarns and the frictional slider were measured in order to study the frictional mechanism of pile fabrics.
The results are as follows.
(1) The frictional force (F) is expressed by the following experimental equation :
F=fAYA+bW
Where, A is the real contact area between the surface of the pile yarns and the surface of the frictional slider, W is the loss energy and fAY and b are constants.
(2) The relation between the frictional force (F) and the pressure (R) is expressed by the following experimental equation :
F=K1Rm+K2Rn
where, K1, K2, m and n are constants.View full abstractDownload PDF (942K) -
Part 4 : An Investigation of the Factors Affecting Frictional Propertieson the Pile FabricsToyonori Nishimatsu, Teiji Sawaki1982 Volume 35 Issue 12 Pages T173-T180

JOURNAL FREE ACCESSThis study aims to investigate experimentally the frictional properties of pile fabrics by changing the sliding speed, the relative humidity, the number of twists of the pile yarns and the frictional direction.
The results obtained are as follows :
(1) The frictional force is affected by the sliding speed and decreases as the sliding speed increases.
(2) As it is found that the fricional force is affected by the relative humidity, the assumption is made that :
F (H) = fAY·A (H) + bW (H)
where, fAY is constant and H shows the relative humidity. The assumption was confirmed experimentally.
(3) The frictional force increases as the number of twists of the pile yarns decreases.
(4) The coefficient of friction obtained by the sliding opposite to the pile lay (μa) is higher than that obtained by the sliding to the same direction as the pile lay (μw).View full abstractDownload PDF (942K) -

JOURNAL FREE ACCESSA test method of crease in wearing was studied on many kinds of textile fabrics using the Monsant Crease Tester prescribed in Method B, JIS L1096.
First, a set of ten photographic standards ranking from class 10 to 1 has been prepared. Then, test conditions and methods of evaluation were investigated to establish a method which has a good correlation with an actual crease in wearing.
On the basis of the experimental results, the atmos pheric condition of 35°C/90% RH for creasing and 20°C/65% RH for recovering has been chosen as the test condition.
It has been found that this test method under these test conditions has a good correlation with an actual crease in wearing.View full abstractDownload PDF (378K) -

JOURNAL FREE ACCESSIn this paper, the effects of dyeing processes on the colourimetric behavior of the disperse-dyed polyester has been studied and following results are obtained.
(1) The saturation and the darkness of the DIN system were remarkably dependent on the dyeing method and after-treatment, i. e., rinsing, soaping and reduction clearing.
(2) The order of decreasing saturation is : dip dyeing > pad steam >pad thermosol, and reduction clearing >soaping > rinsing.
(3) The order of increasing darkness is : dip dyeing pad steam < pad thermosol, and reduction clearing < soaping < rinsing.
(4) A brilliant shade is obtained by the dip dyeing compared with the pad method (steam, thermosol).View full abstractDownload PDF (521K) -
