As a common chemical fiber in textiles, polyester yarn has always been one of the most popular categories in the yarn market. There are many types of polyester yarns on the market, such as POY, DTY, FDY. Do you really know them?

What Is Polyester Yarn?

Polyester is an important variety of synthetic fibers. It is a fiber-forming polymer prepared from terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction – Polyethylene terephthalate (PET), fibers made by spinning and post-processing. Polyester yarn refers to yarn spun from polyester as raw material.

Varieties Of Polyester Filament Yarn

Primary Yarn:

Undrawn yarn (conventional spinning) (UDY), semi-pre-oriented yarn (medium-speed spinning) (MOY), pre-oriented yarn (high-speed spinning) (POY), high-oriented yarn (ultra-high-speed spinning) (HOY) ).

Drawn Yarn:

Drawn yarn (low-speed drawing yarn) (DY), full drawn yarn (spinning and drawing one-step method) (FDY), fully oriented yarn (spinning one-step method) (FOY).

Textured Yarn:

Conventional textured yarn (DY), drawn textured yarn (DTY), air textured yarn (ATY).

Polyester POY

Polyester poy is a polyester pre-oriented yarn ( high-speed spinning ), which needs to be stretched and deformed by a texturing machine to make polyester DTY. It is widely used in textiles, and polyester poy is not directly used for weaving.

According to statistics and forecasts, the global polyester pre-oriented yarn market sales will reach 211 billion US dollars in 2021, and it is expected to reach 332.8 billion US dollars in 2028. The compound annual growth rate region (CAGR) for the period 2022-2028 is 5.9%.

POY refers to pre-oriented yarn. The spinning speed is over 3000 m/min. The winding yarn has a higher degree of orientation than the conventional spinning and winding yarn, and has a certain storage stability than the drawn yarn, but the crystallinity is still very low. Compared with polyester undrawn yarn, polyester POY has a certain degree of orientation and good stability, and is often used as a special yarn for polyester drawn textured yarn (DTY).
The video below describes how polyester POY is processed into polyester high elastic DTY.

Characteristics Of Polyester POY

Polyester POY has high pre-orientation, stable properties, good mechanical properties, high uniformity and good processing performance.

The Use Of Polyester POY

Polyester POY can be made into products with different properties such as drawn yarn, texturized yarn, and air-textured yarn through the processes of drafting, texturing, and air deformation, and can be made into various wool-like, hemp-like, and silk-like products. Suitable for weaving and knitting industries .

DTY refers to drawn textured yarn, which is the finished yarn that is continuously or simultaneously stretched on a texturing machine and processed by a twister.

Polyester DTY uses polyester fiber thermoplastic, twisting first and then untwisting to obtain a spring-like shape, which is similar to twisting, but is actually false twist. Polyester drawn textured yarn is commonly known as polyester elastic yarn, which is divided into high elastic and bottom elastic. kind.

Characteristics Of Polyester DTY

The yarn of polyester DTY is curved, which can give the yarn a fluffy effect after twisting and texturing. Polyester DTY has high bulkiness, good heat insulation, comfortable hand feel, soft luster, high breaking strength and elastic modulus of general polyester, excellent heat setting, good resilience, heat resistance, light resistance, and strong corrosion resistance. , Easy to wash and quick dry and so on.

The Use Of Polyester DTY

Polyester DTY is an ideal raw material for knitting and weaving. It is suitable for making clothing fabrics, bedding, home decoration, clothing, industrial fabrics and automotive fabrics, and is used to weave various simulated silk fabrics.

Characteristic

Stable properties, good mechanical properties, high uniformity, and good processing properties.

High bulkiness, good heat insulation, comfortable hand feel, soft luster, high breaking strength and elastic modulus of general polyester, excellent heat setting, good resilience, heat resistance, light resistance, strong corrosion resistance, easy to use Features such as quick-drying.

High strength, good filament tube formation, small titer, strength, uneven elongation rate, uniform dyeing, etc.

Uses

Polyester POY is mainly used in post-processing production such as the production of DTY, DT, ATY, and can also be directly used in the silk textile industry.

Polyester DTY is an ideal raw material for knitting (weft knitting, warp knitting) or weaving, suitable for making clothing fabrics (such as suits, shirts), bedding (such as quilts, bedspreads, mosquito nets) and decorative items (such as curtain fabrics, sofas) cloth, wall cloth, car interior decoration cloth) and so on. Among them, fine denier silk (especially three-lobed special-shaped silk) is more suitable for silk-like fabrics, and medium and coarse denier silks can be used for wool-like fabrics.

Polyester FDY is mainly used in clothing, textile and industrial industries.

Generally speaking, the price of polyester yarn is DTY>FDY>POY.

The spinning speed of high-speed spinning is 3000-6000 m/min, and the winding polyester yarn with a spinning speed below 4000 m/min has a high degree of orientation, which is a pre-oriented yarn, commonly known as polyester POY (pre-oriented yarn). If stretching is introduced in the polyester spinning process, a wound yarn with high orientation and moderate crystallinity can be obtained, which is a polyester fully drawn yarn, commonly known as polyester FDY (fully drawn yarn).

The yarn raw material of polyester DTY generally uses polyester POY (spinning process is similar to FDY, but the elongation is higher). After twisting, the fibers of the yarn are separated into bulky and irregular cross-sections. The general conventional yarn of polyester DTY has better air permeability than FDY and softer hand feeling than FDY.

If you pull it by hand, generally polyester POY can be pulled longer, and polyester FDY can be pulled less. Because POY is a pre-oriented yarn, it is not fully stretched, and the remaining elongation is more than 50%; while FDY is a fully oriented yarn, and the remaining elongation is generally below 40%, which is relatively stable.
