To mitigate the risk of fire accidents caused by flammable textiles and reduce the potential harm to life and property, the assessment of the burning performance of textile materials has garnered considerable attention worldwide. This article will discuss Textile Flame Retardancy Evaluation. Judging the flame-retardant performance of fabrics generally relies on two aspects. Firstly, the
The Solid State Polymerization (SSP) process refers to the condensation polymerization of solid chips, aimed at increasing molecular weight and intrinsic viscosity (IV). The normal PET Chips are heated to the glass transition temperature (usually 10-40° C below the melting point). The small molecular products are removed by vacuum or inert gas protection (generally high-purity
PET film (polyethylene terephthalate film) is a commonly used plastic film material with excellent physical properties and chemical stability. There are various processes to choose from, among which the coating process is the most common production method. This article will make a comparison of three different PET Film production processes, coating, extruding, and stretching process.
