<P>PROBLEM TO BE SOLVED: To provide a bed sheet, especially a bed sheet which is optimal for a bed for care, in which wrinkles are difficult to be generated. <P>SOLUTION: In the bed sheet consisting of three-dimensional knitting comprising connecting yarn coupling a knitted fabric of an inside and an outside layers and the knitted fabric of the two-layers, the total cover factors (TCF) of the surface knitted fabric is 750-1,250. However, the total cover factor (TCF)=course cover factor (CCF)+wale cover factor (WCF). The course cover factor (CCF) =(the number of courses; pieces/ 2.54 cm)×(thickness of a filament which composes the surface knitted fabric; dtex)<SP>1/ 2</SP>. Wale cover factor (WCF)=(the number of wale; pieces/ 2.54 cm)×(thickness of a filament which composes the surface knitted fabric; dtex)<SP>1/ 2</SP>. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
