Title:
HIGH-DENSITY WOVEN FABRIC AND PRODUCTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2008/056406
Kind Code:
A1
Abstract:
A high-density woven fabric having excellent wind breaking properties which
is a woven fabric comprising, as the warps and/or the wefts, polytrimethylene
terephthalate multifilaments having a single-fiber fineness of 0.01-0.5 dtex,
characterized in that the total cover factor of the warps and wefts is 1,700-3,500
and the air permeability is less than 1.0 cc/cm2·s. This high-density
woven fabric can be obtained by weaving a fabric out of sea-island type composite
fibers in which the sea-component polymer is constituted of polylactic acid
and the island-component polymer is constituted of polytrimethylene terephthalate
and then subjecting the woven fabric to a dissolution treatment to dissolve away
the polylactic acid.
