Abstract
To improve the efficiency of the sewing and handling of soft and flexible fabrics, nine temporary finishing agents for sewing, i.e., trioxymethylene, DL-malic acid, maleic acid, dimethyl oxalate, p-dichlorobenzene, oxalic acid, phthalic acid, naphthalene and benzoic acid were selected taking account of their thermal properties. They were evaluated by measuring the flexural rigidity of the treated fabrics and removal rate of these agents on plain knitted fabrics.
All compounds contributed to increase the rigidity by an application to fabrics. Trioxymethylene, p-dichlorobenzene and dimethyl oxalate were recommended for use in a short duration. Benzoic acid, oxalic acid, maleic acid and phthalic acid were, by contrast, recommended for use in a long duration. All of the latter had carboxy groups in their structure. It was found that all of the latter were very useful as a finishing agent for limp fabrics.
