virgin polyester staple fiber

In the past, cotton is the fiber that common used in multiple industry applications. Cotton fibers are composed of pure cellulose which gives the feeling of soft, fluffy, comfortable and breathable. On the other hand, the cotton product’s life is not long. Cotton is a commodity and can fluctuate in price. This is because it is nature fiber.

Polyester spun yarn has been created in order to imitate cotton. Polyester spun yarn has been appeared for more than half a century. The advantage of Polyester Spun Yarn is more wrinkle resistant than cotton, fades less, and is long lasting and durable.

Polyester spun yarn is made from polyester staple fiber (PSF) and pass through 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 and weaving fabrics, and also used for manufacturing of sewing thread and embroidery yarn.

polyester ring spun yarn, polyester OE spun yarn

Thai Polyester Co., Ltd. is the professional 100% polyester fibers and yarns manufacturer in Thailand, we are also recognize as the biggest 100% polyester spun yarn manufacturer in Thailand. Thai Polyester provides numerous quantities of polyester ring spun yarn and polyester OE spun yarn to the local customers and export to thread suppliers, knitting and weaving manufacturers around the world every year.

According to, the sustainable concept of our company, TPC has started producing recycled polyester fiber and yarn,which made from PET bottles, and reduced using virgin polyester. The company has certified the standard of recycled standard names Global Recycled Standard (GRS) to warrantee our product quality. This indicates that our company also provides both recycled polyester spun yarn and virgin polyester spun yarn which made more choices for our various customers.

A. 2 types of yarn spinning techniques

1. Ring Spinning

Ring spinning is the oldest spinning system. It was based on the first spinning method used and remains popular to this day. The production capacities of ring spinning are low, comparing to rotor, or open-end. However, the quality of final product is the better than the other. The ring spinning system continues to use the widest range of yarn counts as much as possible and can produce very fine yarns.

Ring Spinning

      The ring spinning process is simple. The roving is the input for the process and passes through a basic, usually 3 roll, drafting system. After drafting, the fiber is twisted into a yarn structure by a whirling spindle, which has a removable bobbin on it. The winding of the yarn onto the bobbin takes place due to the traveler and ring combination.

Ring spinning requires a subsequent winding step. That is the full bobbins must be wound onto a cone to create a much larger package that is then usable for weaving or knitting. These additional steps of roving and winding, combined with the slow production rate (when compared to rotor), are the primary reasons for the higher cost differences for ring-spun yarn.

2. Rotor or Open End(OE) Spinning

Rotor or open-end spinning is a faster process than ring spinning, up to 10 times per spindle. From a cost standpoint, it does not require the roving process step and it does not require an extra winding step. Yarn is ready for use directly from the machine. The process today is highly automated and includes automatic piecing (restarting of broken ends) and doffing (removal of full packages).

Rotor or Open End(OE)

The rotor spinning process is difficult to conceptualize. A sliver is used as the input and is fed into a small carding device called a combing roll (or opening roll). This individualizes the fibers and performs the drafting. 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. 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 which is non-renewable polyester. The colors that we provide are:

Raw White (RW)

1.1 Raw White (RW)
      RW is the color of the nature polyester color itself, not pass any color process.

1.2 Dope Dye Black (DDB)
      DDB is the black color that we put black master-batch since the beginning of POY process with high temperature. DDB spun yarn will have non-staining function quality and pale color.

Recycled polyester spun yarn

2. Recycled polyester spun yarn
      Recycled polyester is made from 100% of PET/Polyester waste and post consumed 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. It is a great way to divert plastic from our landfills and the production of recycled polyester requires far fewer resources than new fibers and generates fewer Co2 emissions. The colors of our recycled polyester staple fiber that we provide are: E.

2.1 Raw White (RW)
      RW for recycled polyester is a bit difference from virgin polyester. Its color looks a bit yellow which is natural from the process.

2.2 Dope Dye Black (DDB)
      DDB for recycled polyester looks alike virgin polyester. It also contains black master-batch since the process of melting before injecting. So, we cannot separate between DDB virgin and DDB recycle by vision. But there is a mechanical test to detect that which one is made from recycle and which one is made from virgin. It has a standard to test as well. Normally, we will give third party which qualified by GRS to test and give us certification to prove that fibers or yarns.

C. Spun yarn luster

C. Spun yarn luster

      Luster refers to the degree of light that is reflected from the surface of a fiber or the degree of gloss or sheen that the fiber possesses.

1. Full dull
      Full dull yarns are manufactured from the raw materials which are modified chemically and/or physically to reduce their normal luster. Few of the qualities of full dull yarns are, they have high tenacity, strength and look like cotton fiber. These yarns are of good pendent, soft visual appeal and a strong covering. Full dull type of yarns have various applications in manufacturing apparels, home textiles etc.

2. Semi-dull
      Semi-dull yarn are manufactured from the raw materials which have low luster as compared to partially oriented bright yarns are used to manufacture semi dull polyester textured yarns. Semi dull partially oriented yarns have more strength and durability. The end user applications of semi dull partially oriented yarns are in the garment and apparel industries for weaving and for doing embroidery works. These semi dull yarns are available in various deniers and filaments.
