The fabrics of 8 structures, containing plain, twill, sateen and basket weaves, were made from the identical spun yarn, but varying the yarn density. Half of each sample fabric was treated with a urea-formaldehyde resin. The crease resistances of the samples, treated and untreated, were measured, as described in the preceding papers.
In general, the crease resistance decreased and approached to a constant value, but in some cases it increased through a minimum with the increase of the yarn density.
These results may be explained from a viewpoint that the yarns under stress displaced to the least strain and the freedom of the filaments and yarns in a fabric was dependent on the structure meaand the yarn density.
Among the samples, the crease resistances of the sateen and basket were excellent, but they could be improved slightly by the resin treatment, while the plain, which was improved remarkably, had a lower resistance before the treatment, compared with these of the 1/7-twill, sateen and basket.
Yarn density changes often during the treatment, so the evaluation of the eflect of the resin finish must be made with precaution.
