Abstract: To provide a biaxially stretched polyester resin film that has excellent properties equal to or better than those of biaxially stretched polyester film that does not use recycled raw material, and in particular that has an excellent flexural resistance in low-temperature environments. A biaxially stretched polyester resin film that characteristically satisfies both of the following properties (1) and (2): (1) in differential scanning calorimetry (DSC), after heating from 25° C. to 300° C. at a heating rate of 20° C./minute and holding for 10 minutes at 300° C., the temperature of crystallization during cooling at a cooling rate of 40° C./minute is 160° C. to 180° C.; and (2) the number of pinholes after the execution of 200 repetitive cycles of a flexural fatigue test in a ?10° C. atmosphere using a Gelbo Flex Tester is not more than 10/500 cm2.
Abstract: A water-repellent knitted fabric is a knitted fabric which comprises a multifilament made of a thermoplastic resin and has a water repellent imparted to a surface of the knitted fabric or the multifilament, and satisfies the following conditions (1) to (4): (1) the number of voids between stitches of the knitted fabric is 20 to 40/[12 cm×12 cm], and the voids have a size of 7 to 25 mm2; (2) initial water repellency measured in accordance with a spray method described in JIS L-1092 is at a grade 3 or higher; (3) initial Water drainage is 70% or more; and (4) initial Bursting Strength measured in accordance with a method A described in JIS L-1096 is 200 kPa or more and 500 kPa or less.
