| titleOfInvention | A process for preventing laddering in knitted fabrics |
| abstract | In the manufacture of knitted fabrics from single filaments of a synthetic resinous material in which the filaments cross without being actually knotted or tied, the filaments are treated, before or after knitting, with a solution containing at least one solvent for the filament, at least one liquid diluent miscible with the solvent but incapable of dissolving the filament, and a water-insoluble polymer miscible with the synthetic resinous material of the filament and soluble in the solvent-diluent mixture, and thereafter the treated filament or fabric is dried. The filaments may be of a polyamide and the treating polymer may be the same or another polyamide, polyvinyl formal, polyvinyl acetate or polyvinyl butyral. The liquid mixture may be such that the diluent evaporates more quickly than the solvent or vice versa, and in the latter case the mixture may be incapable of dissolving the filament at room temperature but will do so at raised temperatures, in which event the material may be dried at the temperature at which the liquid will exert a dissolving action. In Example (1) nylon stockings are treated according to a pattern with a solution containing a polyamide 6-6, phenol and acetic acid and dried at 60-70 DEG C., and nylon stockings are similarly treated in Example (2) with a solution containing a polyamide, formic acid and acetic acid and in Example (3) with a solution containing acrylonitrile - butadiene copolymer, phenol, acetic acid, toluene, and methyl ethyl ketone. In Example (4) a nylon filament is treated at intervals along its length with a solution containing polyvinyl formal, formic acid and acetone. A stocking, knitted from the treated filament, is stretched and treated in this condition with a mixture of toluene and ethanol by immersion or with their mixed vapours at 50 DEG to 80 DEG C. The toluene may be replaced by dichloroethane or cyclohexanone. Specification 685,623 and U.S.A. Specification 2,308,593 are referred to. |
