Polyester Filament is made of polyester filament. Polyester is an important variety of synthetic fibers, and is the trade name of polyester fibers in my country. It is a fiber-forming polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation. - Polyethylene terephthalate (PET), fibers made by spinning and post-processing.
Dtex (dtex), referred to as decitex, the symbol is dtex, refers to the weight of 10,000 meters long fiber or yarn under the specified moisture regain, dtex=dg/(L*100000), dtex=g/( L*10000), where dg is the weight of the yarn (or silk) in grams, 1 decigram = 0.1 grams, that is, 1dg=0.1g), and L is the length of the yarn (or silk) (m)
Monofilament: Its fineness is thicker than that of a single filament in a multifilament. The melted synthetic resin is condensed through a thin stream of raw liquid pressed out of the capillary hole of the spinneret. Or spin with a multi-hole spinneret (for example, up to 50 holes), and then wind it into a monofilament bobbin through untwisted drawing and splitting.
Multifilament: It is a twisted or untwisted bundle of filaments spun from a multi-hole spinneret. Multifilaments composed of multiple single fibers are softer than monofilaments of the same denier.
Single yarn: It is a very simple thread.
Multi-plied yarn: The strands are plied and twisted in a certain way to obtain multi-twisted strands, such as double-strand, triple-strand and multi-strand. Mainly used for sewing thread, braided thread or medium-thick and strong fabrics.
Industrial brush filament and Paint brush filament belong to Multifilament.
