Wet processing has been and will remain important to
the textile industry in the future. However, economic forces, market demands,
and environmental concerns will shape the direction that chemical development
for wet processing will take.
General Trends
There are some clear trends apparent for chemical products
destined for the textile wet processing industry.
Global competition is requiring textile chemicals at lower
cost. One way to achieve this goal is to provide high solids concentrates. By
reducing the amount of water to be shipped, transportation costs can be
lowered, leading to lower cost products. One disadvantage of this approach is
the necessarily higher cost per kilogram of the shipped product. Although the
actual cost for use may be lower, the higher initial cost may be a deterrent to
sales.
Another approach to lower chemical costs is to provide the
chemicals in bulk or semi-bulk containers. In this way, the costs for drums and
drum disposal are eliminated.
If the performance of a chemical product can be enhanced,
then the amount of chemical needed for a specific property can be reduced.
Using a more efficient chemical can lower the cost per use and since less
chemical is being used, effluent problems can be minimized.
Combining several chemical auxiliaries into one product is
another approach to lowering overall chemical costs. By reducing the number of
individual products, shipping, storage, and disposal costs are significantly
lowered.
Often, the use of a textile chemical involves generating
undesirable side effects, such as foam and effluent problems. Overcoming these
difficulties is costly in terms of additional chemical requirements and reduced
productivity. One important requirement for competitive textile chemicals will
be fewer problems during use.
