Polyester Yarn Supplier in Pakistan
Polyester is the most widely used synthetic fibre in textiles, and in Pakistan it is used alongside cotton in almost every part of the industry, from blended yarn and uniforms to sewing thread and sports goods. Soltex supplies polyester in the forms manufacturers actually buy: spun polyester yarn, continuous filament yarn, high tenacity industrial yarn, and woven polyester and poly cotton fabrics. We help buyers decide when polyester, cotton or a blend is the better fit, and we specify each yarn and fabric to suit the end use.
Spun Polyester Yarn
Spun polyester yarn is made from polyester staple fibre, typically cotton-type fibre of around 1.2 to 1.5 denier cut to a length similar to cotton, so it can be processed on the same ring and rotor spinning systems. The fibre ends give the yarn a soft, matt surface and a hand closer to cotton than filament yarn has.
Spun polyester is the main raw material for sewing thread and is used for knitted and woven fabrics where strength, low shrinkage and colour retention matter. It is supplied in single and plied forms, with counts written in the English cotton system (Ne), for example 20/2, 30/2, 40/2 and 20/3. For thread products made from this yarn, see our yarn and threads page.
Polyester Filament Yarn: FDY and DTY
Filament yarn is made of continuous fibres that run the full length of the yarn. It is specified by denier (the weight in grams of 9,000 metres) and filament count, written together as, for example, 75D/36F, 150D/48F or 300D/96F. More filaments at the same denier give a softer yarn with finer individual fibres; fewer filaments give a crisper, more durable yarn.
FDY (fully drawn yarn)
FDY is fully oriented, flat filament yarn. It is smooth, uniform and lustrous, and is used for woven fabrics such as linings, taffeta, satin and smooth outer fabrics, and as a base for embroidery and narrow fabrics.
DTY (draw textured yarn)
DTY is produced by drawing and texturing partially oriented yarn (POY), which crimps the filaments and gives the yarn bulk, stretch and a warmer, more natural hand. It is widely used in knitted sportswear, fleece, socks, upholstery and woven fabrics that need cover and comfort. DTY can be supplied intermingled (with tangled filaments for easier processing) or non-intermingled, and in semi-dull, bright or full-dull lustre.
Filament yarn can be raw white for later dyeing or dope dyed, where colour pigment is added to the polymer before spinning. Dope dyed yarn has very good colour fastness and avoids a separate dyeing step, which suits standard colours such as black and navy in larger volumes.
High Tenacity Polyester Yarn
High tenacity (HT) polyester yarn is an industrial filament yarn drawn and heat-set to achieve much higher breaking strength and lower elongation than regular textile polyester. Regular textile filament is typically in the range of about 3.5 to 5 grams per denier; industrial HT yarn is commonly in the region of 7 to 8.5 grams per denier. HT yarn is supplied in coarser deniers, such as 500D, 1000D and 1500D, and in low-shrink or standard-shrink versions depending on whether the end product will be coated or heat-treated.
Typical uses of high tenacity polyester yarn include:
- Industrial sewing threads and bonded threads for bags, footwear, upholstery and tents
- Webbing, straps, lifting slings and seat belts
- Ropes, cords and nets
- Base fabrics for PVC-coated tarpaulins, banners and truck covers
- Sports goods components, including stitching thread and bladder winding thread
When ordering HT yarn, give the denier, the required tenacity and elongation, the shrinkage level, and whether the yarn needs adhesion-activated treatment for coating or rubber bonding.
Polyester and Poly Cotton Fabric Supplier
We supply woven fabrics in 100% polyester and in polyester-cotton blends, in greige or finished form. The most common blends are PC 65/35, where polyester gives strength and easy care, and CVC (chief value cotton, more than 50% cotton), which keeps a more cotton-like hand. These blends are woven in the same weaves as cotton fabrics: poplin for shirting and uniforms, twill and drill for workwear and trousers, and canvas and duck for bags and covers. Construction notation, EPI, PPI and GSM are explained on our weaving and woven fabrics page.
Poly cotton fabric is the standard choice for workwear, corporate uniforms, school uniforms, chef wear, hospital and hotel linen, and any product that must survive frequent industrial laundering. It keeps its shape, resists creasing, dries quickly and holds its colour, while the cotton component adds comfort and absorbency. For heavier blends used in tents and covers, see our canvas and cotton fabric page.
Polyester vs Cotton: Key Property Comparison
Choosing between polyester, cotton and a blend starts with understanding how the two fibres differ. The table below summarises the main properties that matter in yarn and fabric selection. Values are typical textbook ranges for the fibres and will vary with fibre grade and processing.
| Property | Polyester | Cotton | What it means in use |
|---|---|---|---|
| Moisture regain (standard conditions) | About 0.4% | About 7–8.5% | Cotton absorbs sweat and feels cooler; polyester dries much faster. |
| Strength when wet | Essentially unchanged | Increases slightly | Both perform when wet; polyester keeps its higher dry strength. |
| Tenacity (regular grades) | Higher, roughly 3.5–5.5 g/den for textile grades | Lower, roughly 3–5 g/den | Polyester allows lighter fabrics and threads for the same strength. |
| Abrasion resistance | Very good | Moderate | Polyester and blends last longer in workwear and bags. |
| Shrinkage and creasing | Low after heat setting | Higher unless pre-shrunk | Polyester holds its size and shape through washing. |
| Heat behaviour | Softens and melts at about 250–260 °C | Does not melt; scorches at high temperature | Cotton tolerates hot ironing; polyester needs lower iron settings. |
| Density | About 1.38 g/cm³ | About 1.52–1.54 g/cm³ | Polyester gives slightly more cover per gram. |
| Dye class | Disperse dyes, high-temperature dyeing | Reactive, vat, direct and sulphur dyes | Blends need two dye classes to colour both fibres. |
| Sunlight and mildew | Good resistance | Weakens in UV; prone to mildew when damp | Polyester suits outdoor products and storage in humid conditions. |
| Comfort and static | Can feel warm and build static | Breathable, low static | Blends combine comfort with durability. |
In practice, neither fibre is better in every way. Cotton is preferred for next-to-skin comfort and high absorbency; polyester for strength, shape retention and outdoor durability. Blends let you balance the two for the job in hand.
Uses of Polyester Yarn and Fabric
Sports goods
Pakistan's sports goods industry, centred in Sialkot, relies heavily on polyester. Polyester and poly cotton woven fabrics are laminated behind PU and PVC panels to give footballs their shape and durability; multi-ply polyester thread is used for hand-stitching panels; and high tenacity filament is used for winding bladders. We supply these materials together; see our football fabric page for laminating fabrics.
Outdoor and covering products
Because polyester resists sunlight, rot and mildew far better than cotton, it is used in tents, awnings, tarpaulins, truck covers, flags and banners, either as a woven fabric or as the base cloth for coatings.
Workwear and uniforms
PC drill, twill and poplin are the standard fabrics for industrial workwear, security and corporate uniforms, and hospitality wear, because they withstand repeated industrial laundering with low shrinkage and good colour retention.
Threads
Most sewing thread in modern garment production is spun polyester or core-spun polyester, and most heavy industrial threads are bonded polyester or nylon filament. Polyester gives the strength, consistency and colour fastness needed for high-speed sewing.
Home textiles and bags
Poly cotton sheeting is used in hotel and hospital linen; polyester and blended canvas and oxford fabrics are used in school bags, travel bags and luggage linings.
Dyeing Polyester and Colour Fastness
Polyester has a compact, water-repellent fibre structure, so it is dyed with disperse dyes, usually in pressurised high-temperature dyeing machines at around 130 °C, or by thermosol methods for continuous dyeing. After dyeing, a reduction clearing process removes surface dye and improves wash and rub fastness. Poly cotton blends need both a disperse dye for the polyester and a reactive or vat dye for the cotton, applied in one or two baths. Good shade matching on blends depends on a consistent blend ratio in the yarn, which is why we control blend percentages closely.
Colour fastness is assessed by standard laboratory methods and rated on grey scales from 1 (poor) to 5 (excellent), or 1 to 8 for light fastness on the blue wool scale. Commonly specified tests include:
- Washing fastness: colour change and staining after a standard wash cycle.
- Rubbing (crocking) fastness: colour transfer under dry and wet rubbing.
- Light fastness: fading under artificial daylight, important for outdoor products and uniforms.
- Perspiration fastness: colour change and staining with acidic and alkaline perspiration solutions.
- Sublimation fastness: dye migration under heat, relevant for polyester that will be heat-pressed or printed.
We agree the test methods and minimum ratings with you before production, and third-party laboratory reports can be arranged on request where applicable.

Ordering Polyester Yarn and Fabric: Frequently Asked Questions
What is the difference between spun and filament polyester yarn?
Spun polyester is made by spinning short staple fibres into yarn, so it has a soft, cotton-like surface. Filament polyester is made of continuous fibres, so it is smoother, more lustrous and stronger at the same weight. Spun yarn is used for cotton-like fabrics and sewing thread; filament yarn for smooth fabrics, technical uses and bonded threads.
What do FDY and DTY mean?
FDY is fully drawn yarn, a smooth, flat continuous filament yarn. DTY is draw textured yarn, which has been crimped to give it bulk, stretch and a softer, more natural hand. FDY suits smooth woven fabrics; DTY suits knitwear, sportswear and fabrics that need comfort and cover.
What is high tenacity polyester yarn used for?
High tenacity polyester yarn is a filament yarn drawn to give much higher breaking strength than regular textile polyester. It is used for industrial sewing threads, webbing and belts, ropes and nets, coated fabrics, tarpaulins and sports goods components such as winding and stitching threads.
Why choose poly cotton fabric instead of 100% cotton?
Poly cotton fabric is stronger and more abrasion-resistant than cotton of the same weight, shrinks and wrinkles less, dries faster and keeps its colour better through repeated washing. It is the standard choice for workwear, uniforms and hospitality linen, while the cotton content keeps it comfortable to wear.
How is the colour fastness of polyester fabric tested?
Colour fastness is tested with standard laboratory methods for washing, rubbing, light and perspiration, and rated on a grey scale. We agree the test methods and minimum ratings with you before production and can arrange third-party test reports on request where applicable.
How do I specify polyester filament yarn when ordering?
State the denier and filament count, for example 150D/48F, along with FDY or DTY, the lustre (semi-dull, bright or full dull), raw white or dope dyed, intermingled or not, and the quantity and packing. A sample cone or a test report helps us match your current yarn exactly.
