Morphologically stable curtain, morphological evaluation method of curtain, morphological evaluation jig of curtain, and manufacturing method of morphologically stable curtain

摘要

PROBLEM TO BE SOLVED: To "improve shape-stability" and the like by having a maximum width difference of a curtain before/after predefined washing and drying is set 8 cm or less, by having a gap area between a crimp of a curtain which has been folded for storage and the like and an evaluation jig is set a predefined ration or less, and the like.;SOLUTION: In a curtain a which has been washed with a dehydration time of 7 minutes or less and/or dried without suspending after the washing, a maximum width difference Dmax of a curtain width in a curtain height direction position Pv of two different curtains is 8 cm or less. In a curtain 1 and the like which has been folded for storage of 10 days, crimps 3 are formed extending in a curtain height direction V. An evaluation jig 5 in which a substantially-semicircular cutout 4 having a diameter 4L which is substantially the same as a width 3W of the crimp 3 in a front view is brought into contact with the crimp 3. When a bottom 4a of the cutout 4 is in contact with a top 3a of the crimp 2, a gap ration H2 may be 5% or less, in which the gap ratio is obtained by having an area in plane view Ab of a gap B between the cutout 4 and the crimp 3 divided by an area in plane view A4 of the cutout 4.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
