    Abstract: A hygroscopic polyester copolymer contains copolymerized units derived from (1) a hydrophilic compound and (2) a cross-linking agent and has a release parameter DELTA MR of at least 12% so as to be controlled in its moisture absorbing and releasing property. Fibers containing the polyester copolymer may be formed and these may be utilized in materials for underwear, sports wear, interlinings, etc. as highly hygroscopic woven and knitted fabrics, etc.

    Abstract: PCT No. PCT/JP90/01491 Sec. 371 Date Sep. 13, 1991 Sec. 102(e) Date Sep. 13, 1991 PCT Filed Nov. 15, 1990 PCT Pub. No. WO91/07529 PCT Pub. Date May 30, 1991.A rubber-reinforcing polyester fiber composed of a polyester prepared by using 30 to 150 ppm as antimony of an antimony compound and 5 to 60 ppm as germanium of a germanium compound as the polymerization catalyst. The fiber is characterized in that the terminal carboxyl group content is not larger than 25 eq/ton, diethylene glycol content (DEG) is not larger than 1.3% by weight, the intrinsic viscosity (IV) is at least 0.85, the sum (S) of the intermediate elongation and the dry heat shrinkage is lower than 8%, the product between strength and elongation (T 2ROOT E) is at least (2S+5), and the terminal modulus (TM) is not higher than 40 g/d. The polyester fiber is used as a rubber reinforcement.
