This document discusses trends in chemical finishing of textiles. The most important trend is improving cost-efficiency by reducing costs and improving effects while minimizing undesirable side effects. Another trend is developing finishes that are more permanent during washing and cleaning through chemical crosslinking or insoluble films. A third trend is creating finishes that make textiles easier to care for as they need only standard cleaning and are not very sensitive to factors like heat, light or rubbing. The goal of using fewer chemicals is also discussed as large amounts can increase costs and lower quality. The document also covers anti-static finishes, which reduce static electricity, and notes the most common type uses fabric softeners and needs moisture to be conductive.

2. ACTUAL AND FUTURE
TRENDS IN CHEMICAL
FINISHING

3. 1-COST REDUCTION AND GREATER EFFICIENCY
The most important trend in chemical finishing is
characterized by the key term
'BETTER COST-EFFICIENCY
RELATION'.
The general aims are lower costs for the finishing
processes and final products, preferably combined
with improved main effects and less undesirable
side effects of the finish.

4. 2- GREATER PERMANENCE IN WASHING AND
CHEMICAL CLEANING
Permanence in laundering and chemical
cleaning of many finishes has been
improved in the last few years
Mostly by chemical reaction with
functional groups of the fibers by:
 crosslinking of the effect chemicals
formation of insoluble films on the fiber
surface

5. 3-EASIER CARE OF THE FINISHED TEXTILES
Finished textiles with high
performance should need no
special care during their usage.
Standard cleaning methods should
be sufficient and these textiles
should not be very sensitive to
heat, light, rubbing

6. 4-USING FEWER CHEMICALS
Often large amounts of chemicals
are necessary for sufficient effect.
This is then not only a cost problem
for the product, but also a quality
problem for the finished textile.

8. ANTI STATIC FINISH
Reduce static electricity which may
accumulate on fibers.
The most common type of anti-
static finishes are fabric softeners.

9. 1. intermediate conductive
layer “hygroscopic”
2. moisture content
higher conductivity
N.B: lower humidity leads
to lower conductivity
(higher resistance) and
greater problems with static
electricity.
MECHANISMS OF ANTISTATIC FINISHES

10. ANTI STATIC FINISH
Polyether agents have been found to be
useful but should not affect the dye-
equilibrium on fiber.
Anti-static finish prevents dust from clinging to
the fabric.
