TEXTILE FINISHING

APPLICATION TECHNOLOGY OF SOFTENERS IN TEXTILES
FOULARD VS. SPRAY TECHNOLOGY

SOFTENER IMPREGNATION WITH 2 FOULARDS

The most common method of impregnating chemicals in knits and fabrics (immersion) uses two pads. The material squeezes at the first pad’s outlet for the bath’s removal and equalization; the fabric softener is applied on the second pad.

Benefits:

  • Good penetration of the bath in the fiber;
  • Simple process.

Disadvantages:

  • Problems with a dilution of the chemical bath, causing a difference in touch during the process;
  • High frequency of bath changes depending on fiber and color, increasing consumption of fabric softeners;
  • High pick-up foulard output 80% or more! Increases drying energy cost;
  • Use of two foulards increases maintenance costs and occupied area.

HYBRID SYSTEM – FOULARD VS. SPRAYTEX

Optimized process: pre-equalization of moisture on the impregnation pad and then applying the concentrated softener with the SPRAYTEX® applicator. The chemical bath (softener) is covered with spray technology – without physical contact – on the surface of the textile material, with penetration into the fibers. Penetration is a function of the rotary disc’s angular velocity (rpm). This alternative allows you to apply as little as possible and as much as necessary. Less is more!

Benefits:

  • The second pad is dispensed, reducing maintenance costs, the area occupied, and the problems with a dilution of the chemical bath;

  • Reduction in the consumption of fabric softeners due to the change of bath resulting from the fiber and color (compared to the traditional system with two foulards);

  • Uniformity in the application of fabric softener:
    In applying the softener, the conventional system (two foulards) has a dilution factor of the chemical bath, causing a difference in touch during the process. However, every system compensates for such dilution with inherent deficiencies;
  • Reduction in the number of times to prepare the fabric softener bath;

  • Reduction in the volume of effluents, lower content of oils and greases, concomitantly reducing the consumption of fabric softeners significantly;

  • Ease of correction of the final touch of the knit/fabric (new article, different yarn).
    – The adjustment performed on the SPRAYTEX® equipment through the correction of the percentage of application is very simple (no need to keep correcting the bath concentration).
