Definitions

• artificial silk fabric is treated with a dilute aqueous solution or dispersion of an alkaline salt of a resin acid, or with a dilute solution of an alkaline salt of a resin acid in an organic solvent, it is subsequently subjected to a hydrolyzing treatment so as to deposit the resin acid on the fabric.
• the hydrolysis of the resin acid salt may becarried out bytreating the fabric with a large volume of water at a comparatively high temperature, and good results may also be obtained by treatment with a dilute acid. If the ammonium salt of a resin acid be employed, the hydrolysis can be effected by heating the fabric. When according to this invention a dilute solution or dispersion of a resin acid is employed, instead of a salt thereof, no hydrolysis is necessaryand the material, after impregnation, can be merely squeezed and dried.
• the treatment according to this invention is applicable to fabrics made from all types of artificial silk.
• Example 1 Common resin (colophony resin) is dissolved in just sufficient warm sodium hydroxide solution to give a clear solution and this is then diluted with cold water until the concentration of the resin is reduced to about 2 per cent. The fabric to be treated is soaked in this solution at ordinary temperature and the excess squeezed out.
• the fabric is passed several times through a large volume of water at from to centigrade.
• the fabric is then rinsed and dried at a moderate temperature.
• Example 2 Colophony resin is dissolved in just suflicient warm sodium hydroxide to give a clear solution which is then diluted until the concentration of the resin is reduced to about 2 per cent.. The fabric is soaked in this solution at ordinary temperature and the excess squeezed out. It is passed through a bath of hydrochloric acid of from 0.2 to 0.5 per cent strength, washed until free from acid and dried at a gentle heat.
• Example 3 1 part of colophony resin is dissolved in 5 parts of industrial methylated spirit; 0.5 part of strong ammonia diluted with three or four times its weight of water is then added at I finally the remainder of the water making a total of parts. The final solution is clear or slightly cloudy. The fabric is immersed in this, the excess of the solution squeezed out, and the fabric dried at a moderate heat.
• Example 4 the excess, the cloth is dried at a gentle heat.
• Process of treating artificial silk fabric to give it a non-slip finish comprising treating said fabric with a dilute alkaline salt of a resin acid containing not more than 4 per cent of the resin acid, and hydrolyzing the salt by treatment with dilute acid.
