When pressing HTV (Heat Transfer Vinyl) on polyester fabric, it’s essential to follow specific guidelines to prevent damage to the material due to its heat sensitivity. Generally, the recommended temperature for pressing HTV on polyester is between 275°F to 300°F (135°C to 148°C), with a pressing time of about 10 to 15 seconds. Using a heat press that allows for temperature and time settings adjustment is advisable. It is also important to pre-press the fabric for a few seconds to remove wrinkles and moisture, lay the HTV, and then press according to the suggested settings. A protective sheet or parchment paper between the HTV and the heat press plate is recommended to prevent melting or scorching the polyester. Let the design cool before peeling off the carrier sheet, following the HTV manufacturer’s instructions on whether it should be a warm or cold peel.

Polyvinyl chloride, commonly known as PVC, is a popular and versatile synthetic polymer. Its structure is based on the polymerization of vinyl chloride monomers (VCM), resulting in a linear backbone of -CH2-CHCl- repeating units. The presence of the chlorine atom in each repeating unit gives PVC its distinctive properties, such as rigidity, flame resistance, and compatibility with various additives. PVC can be modified into a more flexible form by adding plasticizers, leading to a wide range of applications from rigid piping and window frames to flexible cables and flooring. The structure of PVC can be further modified to improve its heat stability, capacity for blending with other polymers, and processing characteristics, illustrating its adaptability and utility in diverse industrial sectors.
