A Study of Comfort of Slacks Across Knees

摘要

This paper discusses the degrees of comfort of slacks across the knees，the mostelastic parts of them，in order to clarify what slacks could be easier to wear.1.Three pairs of three-quarter Slacks were prepared on the basis of the followingconditions：（a）Knitted textures were selected as clothing materials to test.（b）The pattern design was based on the so-called Bunka-Shiki．（c）In the case offinal sewing，five seams／cm，a needle ＃9 for the knitted textures，and polyesterthreads for the knitted textures were selected．（d）The cuffs measure was thesame in all the cases as what was taken by actual measurement．（e）The easeacross the knees was set variable：8cm，4cm，and 0cm．2.The wearing time lasted eight hours．3.Experimental check points were as fo1lows：（a）Pictures were taken of theexternal changes in form．（b）The subject，having worn the slacks，was interviewedconcerning how comfortable each of them was．（c）The measurements were takenof in the length of the fore parts of the slacks，in the width of the slacks aroundthe knees，and in the thickness of the texture across the knees．4．The findings were as follows（a）The length of time that the slacks wereworn had greater effects on the good-or-bad of the external appearances in form ofslack．than on the degree of comfortin wearing them．（b）Concerning the degreeof comfort，0cm ease was felt to be tight，while 4cm was comfortale，even if thetest textures were readily elastic．（c）The sma11er the dgree of comfort became，the longer the fore part of the slacks became．The same could be found in thetexture around the knee．And the less the degree of comfort was，the worse therecovery of elasticity was，into the so-called knee deformation．
