Car seat finishing auxiliaries of Takamatsu Oil & Fat
Seat comfort improver "EX-700T"
It improves seat comfort without inhibiting flame resisting
property
“Seat comfort,” being comfortable to sit in, is
essential for car seats.“Seat comfort” is, in other
words, flexibility, smoothness and volume.Obviously, a flame
resisting property is essential for car seats.
“EX-700T,” polyester resin based polymer finishing
auxiliaries of TAKAMATSU Oil & Fat, is a high functional
finishing auxiliary that can be used in various processes like
in dye-bath, RC one-bath, usual finishing and spraying (dump-roller)
to produce excellent flexibility because it has a remarkable
affinity with fibers, owing to its similar structure to polyester
fibers.
Moreover, while silicone-based and fluorinated auxiliaries harm
the flame resisting property of polyester, “EX-700T” has
advantages to maximize effects of resin combined flame retardants
for backing, by exercising its characteristic that does not inhibit
the flame resisting property in isolation, being a polyester
resin-based auxiliary.
By using “EX-700T” with silicone-based auxiliaries,
it can cover the distinct waxy hand and flatness of silicone,
producing a soft and voluminous hand.
By using “EX-700T” with fluorine-based water repellent
agents, it can prevent hardening caused by them to minimize degradation
of water repellency, and produce good hand.
The following are treatment recipes for car seat comfort improver “EX-700T” and
the test results of the flame resisting property.

As can be seen in the image, polyester taffeta
finished with “EX-700T” for seat comfort did not
harm the effect of the flame retardant, being able to exercise
the maximum flame resisting property.
