Q polyester resin production process

WendellToland Release Time: June 21, 2024, 6:18 PM

Polyvinyl chloride (PVC) is a popular plastic used in a wide range of products from piping to clothing. Its density plays a key role in determining whether it floats. Typically, PVC has a density around 1.3 to 1.45 g/cm³. Since the density of water is 1 g/cm³, PVC does not naturally float because its density is higher than that of water. However, PVC’s buoyancy can be altered when formed into certain shapes or combined with air pockets, which can reduce its overall density making it capable of floating. For instance, PVC pipes might float when they are not filled with water due to the air inside, but in solid form, PVC tends to sink due to its inherent density.

Q how long does polyester last

Blocking polyester yarn involves reshaping and setting your knitted or crocheted project through heat, as polyester, a synthetic fiber, doesn’t respond to blocking in the same way natural fibers do. Begin by pinning your project to a blocking board according to the desired dimensions. Instead of using water or steam directly, place a damp cloth or towel over your project to protect the yarn. With your iron set to a synthetic setting or the lowest steam setting, gently press the iron over the cloth without directly touching the yarn. This allows the heat to gently reshape the item without damaging the fibers. Allow your project to cool and dry completely before removing it from the blocking board. This method is especially useful for projects that need a little shaping or where stitches need evening out, but always test on a swatch first to ensure the heat does not adversely affect the yarn.
