Abstract: A white polyester film and a method for manufacturing the same are provided. The method for manufacturing the white polyester film includes: providing a recycled polyester material; physically regenerating a part of the recycled polyester material to form physically regenerated polyester chips having a first intrinsic viscosity; chemically regenerating another part of the recycled polyester material to form chemically regenerated polyester chips having a second intrinsic viscosity less than the first intrinsic viscosity; mixing white regenerated polyester chips, the physically regenerated polyester chips, and the chemically regenerated polyester chips according to a predetermined intrinsic viscosity so as to form a polyester masterbatch material; melting and extruding the polyester masterbatch material to obtain the white polyester film having the predetermined intrinsic viscosity.

Abstract: A breathable and waterproof membrane and a method for manufacturing the same, and a breathable and waterproof fabric are provided. The breathable and waterproof membrane is formed by stretching a polyolefin material. The breathable and waterproof membrane has a density ranging from 0.6 g/cm3 to 0.8 g/cm3. A plurality of micropores are formed on the breathable and waterproof membrane, and the plurality of micropores each has a size smaller than 500 nm. The polyolefin material includes: 60 wt % to 80 wt % of a first polypropylene resin, 15 wt % to 30 wt % of a second polypropylene resin, and 1 wt % to 10 wt % of inorganic particles. The second polypropylene resin is a modified polypropylene resin having a hydrophilic group. The second polypropylene resin is different from the first polypropylene resin.

Abstract: A white polyester film with a specific weight of 0.6-1.2 has a three-layered structure containing two outer layers (A) having a combined thickness taking up 2% to 30% of an overall thickness of the film and a middle layer (B), and having air-bubble cells in both the outer layers (A) and the middle layer (B). The outer layers (A) are formed from a polyester resin and inorganic particles. The middle layer (B) is formed of a polyester resin, modified polypropylene resin having a heat distortion temperature above 120° C. and a melt flow index (MI) of 0.2-1 g/10 minutes (at 230° C., with a load of 2.16 kg) via crosslinking with 0.1-3 wt % of peroxide with respect to the weight of the polypropylene resin, and inorganic particles.
