COTTON was the most common fiber used in multiple industry applications in the past. Cotton fibers are composed of pure cellulose, which gives the soft feeling, fluffy, comfortable and breathable. On the other hand, the cotton product’s life is not long-lasting also a commodity product and can fluctuate in price because it is a natural fiber.
Polyester Spun Yarn was created to imitate cotton fiber. However, Polyester Spun Yarn has appeared for more than half a century. The advantages of Polyester Spun Yarn is better wrinkle-resistant, fades less, long-lasting and durable.
Polyester spun yarn is made from polyester staple fiber (PSF) and passes through the spinning process. Polyester spun yarn is obtained from both virgin polyester staple fiber and recycled polyester staple fiber. Polyester spun yarn is mostly used for knitting, weaving fabrics, manufacturing sewing thread, and embroidery.
Thai Polyester Company is a professional manufacturer of 100% polyester fiber and yarn, the biggest Polyester Spun Yarn supplier in Thailand. Plus, Thai Polyester Company provides considerable quantities of Polyester Ring-Spun Yarn and Polyester OE Spun Yarn. National and international thread suppliers knitting and weaving manufacturers rely on us.
According to our company's sustainable concept, TPC has started producing recycled polyester fiber and yarn made from PET bottles and reduced using virgin polyester. The company has also certified the recycled international standard by Global Recycled Standard (GRS) to guarantee that our product has high-quality and genuinely recycled. The company provides recycled and virgin Polyester Spun Yarn to suit all customers’ usages.

Ring spinning is the oldest spinning system. It was based on the first spinning method that remains popular nowadays. Ring Spun production capacity is low compared to the rotor or open-end. However, the quality of the finished product is better than the others because the ring-spinning system continues using the widest range of yarn count as much as possible and produces the finest yarns.
Ring spinning requires a subsequent winding step. Full bobbin must be wound onto a cone to create a much larger package usable for weaving or knitting. These additional steps of roving and winding, combined with the slow production rate (compared to rotor), are the primary reasons for the higher cost differences for ring-spun yarn.
Rotor or open-end spinning is faster than ring spinning, up to 10 times per spindle. From a cost standpoint, it does not require the roving process and it does not require an extra winding step. Yarn is ready to use directly from the machine. Currently, the process is highly automated and includes automatic piecing (restarting of broken ends) and doffing (removal of complete packages).
The rotor spinning process is difficult to conceptualize. The sliver is the input fed into a small carding device called a combing roll (or opening roll). This process individualizes the fiber and performs the drafting. Next, the loose fibers are sucked into a rotating rotor cup where they are attached to the rolling, open-end of yarn found there, thus the name, open-end spinning. Finally, the yarn is withdrawn and the process becomes continuous.

1. Virgin Polyester Spun Yarn
Virgin polyester is made from a non-renewable resource using an energy-intensive
process. So, virgin polyester spun yarn is produced from PSF non-renewable polyester. The
colors we provide are:
1.1 Raw White (RW)
RW is the color of the nature polyester color
itself, not passing any color processes.
1.2 Dope-Dyed Black (DDB)
DDB is the black color that the masterbatch has been put since at the beginning of the
POY process with high temperature. Consequently, DDB spun yarn will have non-staining
function quality and pale color.
2. Recycled polyester spun yarn
Recycled polyester is made from 100% waste PET and post-consumer PET bottles
(flakes). Recycled polyester, also known as r-PET, is obtained by melting down existing
plastic and re-spinning it into new polyester fiber. Another good choice for diverting plastics
from the landfill and producing recycled polyester requires far fewer resources than new
fibers and generates fewer Co2 emissions.
Polyester Spun Yarn Product Polyester spun yarn has a long continuous length of fibers,
suitable for the textile industry such as sewing, crocheting, knitting, weaving, embroidery,
rope making, etc.
We provide:

2.1 Raw White (RW)
RW recycled polyester is slightly different from virgin polyester; its color is yellowish
naturally.
2.2 Dope-Dyed Black (DDB)
DDB recycled polyester looks exactly like virgin polyester because the black masterbatch
is mixed in the melting process before injecting. We cannot separate between DDB virgin
and DDB recycle by vision. But there is a mechanical test to detect which is recycled or
virgin. Our recycled product is certified by GRS, a voluntary product standard for tracking
and verifying recycled materials' content in a final product.
Luster refers to the degree of light reflected from fiber surfaces or the degree of gloss or sheen that the fiber possesses.
1. Full dull
Full dull yarns are manufactured from raw materials modified chemically and physically
to reduce their normal luster. A few of the qualities of full dull yarns have high tenacity and
strength and look like cotton fiber. In addition, these yarns are of good pendent, soft visual
appeal and a strong covering. Full dull yarns have various applications in manufacturing
apparel, home textiles, etc.
2. Semi-dull
Semi-dull yarn is manufactured from raw materials with low luster compared to partially
oriented bright yarns used to manufacture semi-dull polyester textured yarn. Semi-dull
partially oriented yarn has more durability properties. The end-user applications of semi-dull
partially oriented yarn are in the garment and apparel industries for weaving and
embroidery works. These semi-dull yarns are available in various deniers and filaments.
Polyester spun yarns are the long and continuous length of fibers, suitable for the production of textiles, sewing, crocheting, knitting, weaving, embroidery, rope making, etc.
