Carboxyl End Groups In PET Chips

Polyethylene terephthalate (PET) is synthesized through the condensation of terephthalic acid (PTA) and ethylene glycol (EG). Its molecular backbone comprises rigid benzene rings and flexible alcohols, making it a saturated linear polymer. PET is a milky white or light yellow, highly crystalline polymer with a smooth, glossy surface. It boasts excellent physical and mechanical properties

Easy Dyeing Fibers

The dyeing of fibers is an energy-intensive process. The most widely used regular polyester fibers face challenges such as difficult-to-control dyeing processes, increased dyeing costs, higher dye content in wastewater, and significant damage to fiber properties. Moreover, conventional dyeing methods pose environmental concerns. Easy dyeing fibers align with environmental requirements and aim to reduce costs and

Synthetic Fibers

Synthetic fibers are chemically manufactured fibers with suitable molecular weight and solubility (or meltability), obtained through the spinning and post-processing of linear polymers. Unlike natural and regenerated fibers, the production of synthetic fibers is not constrained by natural conditions. In addition to the general superior properties of chemical fibers, such as high strength, lightweight, easy

High Shrinkage Fibers

Fibers with a boiling water shrinkage rate of around 20% are referred to as regular shrinkage fibers, while fibers with a rate of 35-45% are called high shrinkage fibers. Classification  (1) Classified by composition, there are two types: high-shrinkage polyacrylonitrile fibers (PAN) and polyester fibers (PET). Our company can supply polymers for boiling water rate

Why Need Sizing?

The filament is composed of multiple individual fibers, such as 165dtex/48f, indicating that 48 individual fibers are combined to form a filament with a total denier of 165dtex. During the production process, the filament undergoes various processes such as winding, combining, twisting, and finishing while under tension. In the weaving process, it experiences repeated friction

Solid State Polymerization (SSP)

The Solid State Polymerization (SSP) process refers to the condensation polymerization reaction of solid chips, aiming to increase the 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 taken away by vacuum or inert
