Polyethylene terephthalate, commonly known as PET resin, is one of the most widely used polyester materials in global manufacturing. It is used to produce beverage bottles, food packaging, sheets, films, textile fibers, industrial filaments, strapping, and many other products. PET manufacturers offer different grades according to the required processing method, intrinsic viscosity, crystallization behavior, appearance,
From Commodity Polyester Yarn to Functional Fiber Opportunities The polyester industry has grown rapidly over the past decades. However, growing competition in conventional polyester yarn markets has pushed many manufacturers to explore differentiated, higher-value fiber applications. For polyester filament producers, developing functional fibers and specialty textile materials is becoming an important strategy to improve product
Method of Analysis (MOA) for Water-Soluble Polyester (WSP) Resin 1. Intrinsic viscosity Capillary viscometer method 1.1 Summary The flow times of a pure solvent and a specimen solution at a concentration of 0.005 g/mL are measured at 25 ℃. The intrinsic viscosity value is calculated from the measured flow time and the concentration of the specimen
The performance of textile sizing agents significantly impacts both production efficiency and product quality. Furthermore, as the proportion of synthetic fibers in textile production continues to rise, the overall demand for synthetic sizing agents is increasing. Traditional synthetic sizing agents, such as Polyvinyl Alcohol (PVA), cause significant environmental pollution. Consequently, driven by the dual requirements
Water soluble polyester resin is increasingly recognized as an essential, high-performance, and environmentally friendly material in the textile sector. By utilizing water as its dispersion medium, it aligns perfectly with the principles of green chemistry. Boasting exceptional adhesion and film-forming capabilities, this resin has become a cornerstone in various textile processes, ranging from yarn sizing
