Title:
FABRIC YARN FOR PAPER MAKING AND WOVEN FABRIC FOR PAPER MAKING MANUFACTURED USING THE YARN
Document Type and Number:
WIPO Patent Application WO/2007/029752
Kind Code:
A1
Abstract:
Disclosed is a fabric yarn for use in paper making, which is excellent in abrasion resistance,
stiffness and morphologic stability. Also disclosed is a woven fabric for use
in paper making, which is manufactured using the yarn. The fabric yarn comprises
a base resin having a viscosity average molecular weight of 500,000 or lower,
a high molecular weight resin having a viscosity average molecular weight of
500,000 or lower and contained in the base resin, and an ultra-high molecular weight
resin having a viscosity average molecular weight of 1,000,000 or higher and
contained in the base resin. In the fabric yarn, the sum of the high molecular weight
resin content and the ultra-high molecular weight resin content is 30% by mass
or less based on the mass of the finished yarn. The woven fabric comprises the fabric
yarn as at least a part thereof. In the fabric yarn, the base resin is preferably
at least one reactive resin selected from a polyamide resin and a polyester resin,
and the high molecular weight resin and the ultra-high molecular weight resin
are preferably modified with an unsaturated carboxylic acid compound.
