The characteristics of polyester filament

The characteristics of polyester filament

The characteristics of the terylene yarn can withstand chemicals and frequent washing, reduce clothes fade and fade, so, hotel uniforms, sportswear, denim Stonewash or children's clothing are made of polyester filament. Comparatively, polyester fiber is more tough than rayon. When embroidering, the machine runs at a high speed, and the polyester wire with high tenacity can bear greater tension. Moreover, it has high fire resistance. Even if the clothing is close to the flame, it is not easy to touch the fire.

1 Introduction editor

Polyester fiber is an important variety of synthetic fiber, and it is the commodity name of polyester fiber in our country. It is a pure terephthalic acid (PTA) or terephthalic acid methyl ester two (DMT) and ethylene glycol (EG) as a fiber polymer, polyethylene terephthalate as raw materials by esterification or transesterification and polycondensation prepared (PET), the spinning and postprocessing fibers.

2 feature editor

The yarn quality of polyester fiber is not more stable than rayon, but more elastic. Can cut a rayon thread to do the test, pull, and then relax, find embroidery line won't shrink; on the contrary, the polyester yarn, after pulling once relaxed, it will return to its original length, which sometimes leads to flower fold, so online tension adjustment, need to be more accurate.

3 category editor

1. primary filaments: Virgin silk (conventional spinning), UDY, semi pre oriented silk (medium speed spinning) (MOY), pre aligned silk (high speed spinning) (POY), high orientation yarn (ultra high speed spinning) (HOY).

2. stretch wire: stretch silk (low speed stretch yarn), (DY), full stretch silk (spinning stretch one-step method) (FDY), all take silk (spinning one-step) (FOY).

3. textured yarns: conventional textured yarn (DY), stretch textured yarn (DTY), and air textured yarn (ATY).

Among them, DTY, Draw, texturing, yarn stretch textured yarn, also known as polyester low stretch yarn, is a machine on a continuous or simultaneous tensile deformation processing of finished silk.

FDY, Fully, drawn, yarn full stretch yarn. Has nothing to do with the production process but widespread, turn it into a spinning one-step process code, can use low-speed and high-speed spinning drawing winding, two steps to complete in a spinning machine, the production cost is low, and the product quality is stable, less broken filament head, dyeing uniformity.

DTY fibers are crimped and FDY fibers are straight.

4 major application editors

Polyester silk products are mainly used in covering yarn, socks, yarn, gloves, carpets, curtains and other fields.

5 identification methods editor

Identification of rayon, silk, polyester silk artificial mercerized Ze bright, feel slightly rough, and clammy feeling, let go, hand clenched after more wrinkles, there are still leveled marks, with tongue wet rub out of silk, rayon straight easily broken and broken, the elastic is not dry the same. Silk soft luster, soft, delicate texture, rubbing can emit special sound, commonly known as the "silk scrooping" or "sound", let go with hand clenched, wrinkles and is not obvious, silk goods dry silk elastic consistency. Polyester filament reflecting strong stiffness, rebound quickly, crisp, good wrinkle resistance, strong, not easy to break.

6 knowledge editor

Polyester fiber belongs to the characteristics of chemical fiber, chemical fiber and natural fiber;

Polyester silk chemical fiber has a wide range of applications in the application, in addition to traditional clothing, is the industry, such as automobiles, buildings, buildings, indoor and outdoor decoration, labor protection and other fields of development. The development direction of chemical fiber application turns to non clothing field. The proportion of non chemical fiber used for clothing in East Asia is increasing year by year, especially for some excellent properties of chemical fiber, which is suitable for the choice of the specific industries, and is in a special important position.

1, recycled fiber: his chemical composition is the same as natural cellulose, and the physical structure has changed, so it is called regenerated cellulose fiber. Such as viscose fiber, acetate fiber, copper ammonia fiber and so on, China mainly produces viscose fiber. Features: soft feel, good luster, good moisture absorption, good air permeability, good dyeing property (not easy to fade). The disadvantage is that wet fastness is poor, that is, when the water strength is low.

2, synthetic fibers, polyester, features: strength and good wear resistance, stiffness, deformation, not easy to wash and wear reputation, not easy to fade. The disadvantage is poor water absorption. Nylon: features: high strength, good wear resistance, ranking first in the fiber. The disadvantages are as good as moisture absorption and breathability of polyester. Acrylic fiber features: polished than wool, silk fiber good. But the wear resistance is poor. In addition, vinylon polypropylene, spandex etc..
