Abstract
The application of resin finishes to textile fabrics raises many interesting problems, and it was felt that a survey of the actual quality of finished fabrics supplied to the retail trade would provide interesting data. A detailed investigation was carried out on 260 fabrics crease‐resisted with urea‐formaldehyde resins. The results are summarised, and observations, of interest to the technician, are made on the possible causes of some of the more outstanding faults.The most important factor, from a consumer's point of view, is the ability of the fabric to recover from creasing; next comes wash fastness (in retention of colour, overall fabric dimensions, and crease‐resistant properties), followed by fastness to light, and the degree of freedom from chemicals which have been used in the process.The survey has shown that some fabrics could be regarded as quite satisfactory, and that a great many could have been considerably improved by adequate process control. On the other hand, a number were regarded as completely unsatisfactory.Those fabrics with a crease‐recovery of the order of 90.0% which were wash fast, dimensionally stable, dyed with dyes of good light fastness, and with a relatively low free formaldehyde figure were considered to be satisfactory. Failure in any one item of the foregoing was regarded as an undesirable feature.
