INDUSTRIAL APPLICATION OF CONTINUOUS WET-ON-WET TREATMENTS OF FABRIC WEBS
The impregnation of a fabric is often carried out on a pad. For this process use is made of a dry fabric. If use could be made of a wet fabric, energy savings could be obtained as a result of the omission of a drying stage. The investigation deals with an impregnation process, frequently carried out in the textile finishing industry. It includes the impregnation of a dry fabric with a resin to make the fabric crease resistant. It has been examined in which way this impregnation can be carried out in practice without applying a preliminary drying stage. The following methods have been tested in Dutch textile finishing mills: - impregnation of wet fabric on a pad in a modified way; - impregnation of wet fabric by means of engraved rollers. Before padding wet fabric it is necessary to determine parameters. These parameters enable the calculation of the conditions to obtain a uniform impregnation of a batch of fabric. The parameters depend on the type of chemical, fabric and on the fabric speed. The impregnation process using engraved rollers is significantly less dependent on different factors.
