4.Functional finish and new technology in future |
The purpose of functional finishes is to allow all the textiles including
apparel and technical for all end-use, high-grade functions. The utilization
of so called nanotechnology can not be ignored to secure further advantages.
Nanotechnology is indispensable in the design of new products with specialized
features through the control of nano structures. Scientists expect that nano
structure will be used to build separate parts or to construct large particles
or fibers. It stimulates innovation in fiber, film and coating technology and
may help to make up large materials like building blocks.
Recently, a Japanese textile processor has developed a new technology, which
is the coating of a very thin (nano level ) metal film on a sheet consisting
of woven, knitted or nonwoven fabric. This method does not use any adhesive such
as a binder, and the metal attaches to the sheet only by physical energy, that
is, molecular or atomic attraction. By attaching the metal film on the surface
of the sheet, new performance of hydrophilic properties, electromagnetic shielding
and UV protection are attained. Further advantages such as high heat insulation
are also realized. Many creative nano technologies will be released in the future
market to differentiate the effects of functional finishes. It is undeniable
that functional finish is a technical bridge for harmonization with the environment
and production. |
